1pid label text239424767 0 android studio emulator: WARNING: Increasing RAM size to 1024MB <p>I am trying to build my first android application in Android Studio, following the tutorial <a href="https://developer.android.com/training/basics/firstapp/creating-project.html" rel="nofollow">https://developer.android.com/training/basics/firstapp/creating-project.html</a>, using AndroidStudio 2.1.2. </p> <p>Whenever I run the emulator, I get this error message:</p> <blockquote> <p>Android Emulator could not allocate 1.0 GB of memory for the current AVD configuration. Consider adjusting the RAM size of your AVD in the AVD Manager. Error detail: QEMU 'pc.ram': Cannot allocate memory</p> </blockquote> <p>Decreasing the size of the memory on the Nexus5x emulator has no effect, so the error message still says "could not allocate 1.0 GB", even when I adjust the memory of the AVD to 256MB. The app needs to run on Android 6.0, with a Nexus5x emulator, so I can't try with a different emulator.

They work OK in that they function correctly and when I <code>exit 0</code> the build succeeds and when I <code>exit 1</code> the build fails with an error. However, that error is enormous, and goes something like this:</p> <pre><code>The command "if Release == Debug goto Foo if Release == Release goto Bar exit 0 :Foo mkdir "abc" copy "$(TargetDir)file.dll" "abc" [...] " exited with code 1. </code></pre> <p>You get the idea. The entire script is always dumped out as part of the error description. The entire script is also dumped out in the Output window while the build is happening, too. So, why have I seen various references on the web to using <code>echo</code> in these scripts? For example, here's part of an example on one particular site:</p> <pre><code>:BuildEventFailed echo POSTBUILDSTEP for $(ProjectName) FAILED exit 1 :BuildEventOK echo POSTBUILDSTEP for $(ProjectName) COMPLETED OK </code></pre> <p>Is there a way to get Visual Studio to suppress all script output apart from what is <code>echo</code>ed (and therefore using <code>echo</code> only to output what you want would make sense), or are these examples just misguided and they don't realize that the whole script is always dumped out?</p>2834633552 0 <p>There are a few ways to do this:</p> <p>1) PHP: Using PHP, you can simply include an html file into another one</p> <pre><code><?php include('fileOne.html'); ?> </code></pre> <p>2) jQuery: Using jQuery, you can load an HTML page dynamically into another (this is kind of hacky in my opinion):</p> <pre><code><html> <head> <script src="jquery.js"></script> <script> $(function(){ $("#includedContent").load("b.html"); }); </script> </head> <body> <div id="includedContent"></div> </body> </html> </code></pre> <blockquote> <p>Source: <a href="http://stackoverflow.com/questions/8988855/include-another-html-file-in-a-html-file">Include HTML Page via jQuery</a></p> </blockquote> <p>3) Framework: Using a framework like Python/Django, you can use {% include %} blocks to create standalone html files that can be reused like blocks.</p> <pre><code><html> {% include 'navbar.html' %} </html> </code></pre> <p>My honest recommendation is #2 if you have to stay with just raw html, otherwise, if you are using PHP then includes are a no brainer.

Please be gentle, I am a noob, so, this might be a duplicate. Still, even hinting to that might help me and others finding an appropriate answer.</p> <p><strong>The Function</strong></p> <pre><code>$.fn.facebookEvents = function(options){ var fbEvents = 'https://graph.facebook.com/'+options.id+'/events/?access_token='+options.access_token+'&since=now&limit=500'; var events = []; $.when($.getJSON(fbEvents)).then(function(json){ $.each(json.data, function(){ $.getJSON('https://graph.facebook.com/'+this.id+'/?access_token='+options.access_token, function(jsonData){ events.push(jsonData); console.log(events); // here array "events" is filled successively }); console.log(events); // here array "events" remains empty }); }).done(function(){ $("#fb_data_live").html( $("#fb_events").render(events) ); }); }; </code></pre> <p>What happens in this function, is an AJAX Call (via jQuerys getJSON shorthand) for the event list of a Facebook Page. This will return a list of JSON objects representing each date. Example of one object as response:</p> <pre><code>{ "end_time": "2017-03-16T23:00:00+0100", "location": "Yuca K\u00f6ln", "name": "K\u00f6rner // G\u00e4nsehaut Tour 2017 // K\u00f6ln", "start_time": "2017-03-16T20:00:00+0100", "timezone": "Europe/Berlin", "id": "985939951529300" }, </code></pre> <p>Unfortunately, these are missing the details we need. They are hidden (nested) and can be found, after making a second getJSON (line 8 in the function), using the individual "id" of each object. Now Facebook replies:</p> <pre><code>{ "description": "http://www.eventim.de/koerner\nTickets ab sofort exklusiv auf eventim.de und ab MI 07.09. \u00fcberall wo es Tickets gibt sowie auf contrapromotion.com.", "end_time": "2017-03-16T23:00:00+0100", "is_date_only": false, "location": "Yuca K\u00f6ln", "name": "K\u00f6rner // G\u00e4nsehaut Tour 2017 // K\u00f6ln", "owner": { "name": "K\u00f6rner", "category": "Musician/Band", "id": "366592010215263" }, "privacy": "OPEN", "start_time": "2017-03-16T20:00:00+0100", "timezone": "Europe/Berlin", "updated_time": "2016-09-28T10:31:47+0000", "venue": { "name": "Yuca K\u00f6ln" }, "id": "985939951529300" } </code></pre> <p>Et voila, the details I was looking for. After making this second (nested) AJAX call, I push the JSON data in the array "events" (line 12). </p> <p><strong>The Problem</strong></p> <p>This should fill up the array with every .each iteration.

The system I work on uses version numbers such as 11.50.UC3, where the U indicates 32-bit Unix, and the C3 is a minor revision (fix pack) number; other letters are used for other platform types. (I'd not recommend this scheme, but it works.)</p> <p>There are a few golden rules which have not so far been stated, but which are implicit in what people have discussed.</p> <ul> <li>Do not release the same version twice - once version 1.0.0 is released to anyone, it can never be re-released.</li> <li>Release numbers should increase monotonically. That is, the code in version 1.0.1 or 1.1.0 or 2.0.0 should always be later than version 1.0.0, 1.0.9, or 1.4.3 (respectively).</li> </ul> <p>Now, in practice, people do have to release fixes for older versions while newer versions are available -- see GCC, for example:</p> <ul> <li>GCC 3.4.6 was released after 4.0.0, 4.1.0 (and AFAICR 4.2.0), but it continues the functionality of GCC 3.4.x rather than adding the extra features added to GCC 4.x.</li> </ul> <p>So, you have to build your version numbering scheme carefully.</p> <p>One other point which I firmly believe in:</p> <ul> <li>The release version number is unrelated to the CM (VCS) system version numbering, except for trivial programs. Any serious piece of software with more than one main source file will have a version number unrelated to the version of any single file.</li> </ul> <p>With SVN, you could use the SVN version number - but probably wouldn't as it changes too unpredictably.</p> <p>For the stuff I work with, the version number is a purely political decision.</p> <p>Incidentally, I know of software that went through releases from version 1.00 through 9.53, but that then changed to 2.80. That was a gross mistake - dictated by marketing. Granted, version 4.x of the software is/was obsolete, so it didn't immediately make for confusion, but version 5.x of the software is still in use and sold, and the revisions have already reached 3.50. I'm very worried about what my code that has to work with both the 5.x (old style) and 5.x (new style) is going to do when the inevitable conflict occurs. I guess I have to hope that they will dilly-dally on changing to 5.x until the old 5.x really is dead -- but I'm not optimistic. I also use an artificial version number, such as 9.60, to represent the 3.50 code, so that I can do sane <code>if VERSION > 900</code> testing, rather than having to do: <code>if (VERSION >= 900 || (VERSION >= 280 && VERSION < 400)</code>, where I represent version 9.00 by 900. And then there's the significant change introduced in version 3.00.xC3 -- my scheme fails to detect changes at the minor release level...grumble...grumble...</p> <p><em>NB</em>: Eric Raymond provides <a href="http://en.tldp.org/HOWTO/Software-Release-Practice-HOWTO/naming.html" rel="nofollow noreferrer">Software Release Practice HOWTO</a> including the (linked) section on naming (numbering) releases.</p>1026556981 0 <p>The <code>using</code> statement is really the preferred solution.

This means that say you go from <code>yoursite/page.html#page1</code> to <code>yoursite/page.html#page2</code> you can track that change, and because we are using hashes it can be picked up by bookmarks and back and forward buttons.</p> <p>You can find a great way to bind to hash changes using the jQuery History project <a href="http://www.balupton.com/projects/jquery-history" rel="nofollow noreferrer">http://www.balupton.com/projects/jquery-history</a></p> <p>There is also a full featured AJAX extension for it, allowing you to easily integrate Ajax requests to your states/hashes to transform your website into a full featured Web 2.0 Application: <a href="http://www.balupton.com/projects/jquery-ajaxy" rel="nofollow noreferrer">http://www.balupton.com/projects/jquery-ajaxy</a></p> <p>They both provide great documentation on their demo pages to explain what is happening and what is going on.</p> <p>Here is an example of using jQuery History (as taken from the demo site):</p> <pre><code>// Bind a handler for ALL hash/state changes $.History.bind(function(state){ // Update the current element to indicate which state we are now on $current.text('Our current state is: ['+state+']'); // Update the page"s title with our current state on the end document.title = document_title + ' | ' + state; }); // Bind a handler for state: apricots $.History.bind('/apricots',function(state){ // Update Menu updateMenu(state); // Show apricots tab, hide the other tabs $tabs.hide(); $apricots.stop(true,true).fadeIn(200); }); </code></pre> <p>And an example of jQuery Ajaxy (as taken from the demo site):</p> <pre><code> 'page': { selector: '.ajaxy-page', matches: /^\/pages\/?/, request: function(){ // Log what is happening window.console.debug('$.Ajaxy.configure.Controllers.page.request', [this,arguments]); // Adjust Menu $menu.children('.active').removeClass('active'); // Hide Content $content.stop(true,true).fadeOut(400); // Return true return true; }, response: function(){ // Prepare var Ajaxy = $.Ajaxy; var data = this.State.Response.data; var state = this.state; // Log what is happening window.console.debug('$.Ajaxy.configure.Controllers.page.response', [this,arguments], data, state); // Adjust Menu $menu.children(':has(a[href*="'+state+'"])').addClass('active').siblings('.active').removeClass('active'); // Show Content var Action = this; $content.html(data.content).fadeIn(400,function(){ Action.documentReady($content); }); // Return true return true; </code></pre> <p>And if you ever want to get the querystring params (so <code>yoursite/page.html#page1?a.b=1&a.c=2</code>) you can just use:</p> <pre><code>$.History.bind(function(state){ var params = state.queryStringToJSON(); // would give you back {a:{b:1,c:2}} } </code></pre> <p>So check out those demo links to see them in action, and for all installation and usage details.</p> <hr> <p>Edit: After seeing your code, this is all you would have to do to use it with jQuery History.</p> <p>Change:</p> <pre><code>$('.tabbed_content .tabs li a').live('click', function (e){ e.preventDefault(); switchTab($(this)); }); </code></pre> <p>To:</p> <pre><code>// Bind a handler for ALL hash/state changes $.History.bind(function(state){ switchTab(state); }); </code></pre> <p>Or if you plan to use jQuery History for other areas too, then we would want to ensure that we only call switchTab for our tabs and not all hashes:</p> <pre><code>// Bind a handler for ALL hash/state changes $.History.bind(function(state){ if ( $('.tabbed_content > .content > li[id='+state+']').length ) switchTab(state); }); </code></pre> <p>We no longer use a onclick event, instead we bind to jQuery History as that will detect the hashchange. This is the most important concept to understand, as for instance if we bookmark the site then go back to it, we never clicked it. So instead we change our clicks to bind to the hashchange. As when we click it, bookmark it, back or forward, the hashchange will always fire :-)</p>11412627676 0 Passing Html tag in Update query <p>There is an existing table in database where I want to update one column.

As an example, if a table has two rows, it may choose a sequential table scan for the portion of the JOIN that uses that table, whereas if it has 10000+ rows, it may choose to use an index or hash scan (if either of those are available.) Incidentally, it used to be possible to trigger poor query plans in Postgres by joining VIEWs instead of actual tables, since there were no estimated sizes for VIEWs.</p> <p>Part of how Postgres constructs its query plans depend on tunable parameters in its configuration file.

There are certain circumstances with the other solution proposed where the label colours appear incorrect (using the system default instead of the overridden colour). This happens while scrolling the list of items.</p> <p>In order to prevent this from happening, we can make use of method swizzling to fix the label colours at their source (rather than patching them after they're already created).</p> <p>The <code>UIWebSelectSinglePicker</code> is shown (as you've stated) which implements the UIPickerViewDelegate protocol. This protocol takes care of providing the NSAttributedString instances which are shown in the picker view via the <code>- (NSAttributedString *)pickerView:(UIPickerView *)pickerView attributedTitleForRow:(NSInteger)row forComponent:(NSInteger)component</code> method. By swizzling the implementation with our own, we can override what the labels look like.</p> <p>To do this, I defined a category on UIPickerView:</p> <pre><code>@implementation UIPickerView (LabelColourOverride) - (NSAttributedString *)overridePickerView:(UIPickerView *)pickerView attributedTitleForRow:(NSInteger)row forComponent:(NSInteger)component { // Get the original title NSMutableAttributedString* title = (NSMutableAttributedString*)[self overridePickerView:pickerView attributedTitleForRow:row forComponent:component]; // Modify any attributes you like. The following changes the text colour. [title setAttributes:@{NSForegroundColorAttributeName : [UIColor redColor]} range:NSMakeRange(0, title.length)]; // You can also conveniently change the background of the picker as well. // Multiple calls to set backgroundColor doesn't seem to slow the use of // the picker, but you could just as easily do a check before setting the // colour to see if it's needed. pickerView.backgroundColor = [UIColor yellowColor]; return title; } @end </code></pre> <p>Then using method swizzling (<a href="http://stackoverflow.com/a/5372042/1270148">see this answer for reference</a>) we swap the implementations:</p> <pre><code>[Swizzle swizzleClass:NSClassFromString(@"UIWebSelectSinglePicker") method:@selector(pickerView:attributedTitleForRow:forComponent:) forClass:[UIPickerView class] method:@selector(overridePickerView:attributedTitleForRow:forComponent:)]; </code></pre> <p>This is the Swizzle implementation I developed based off the link above.</p> <pre><code>@implementation Swizzle + (void)swizzleClass:(Class)originalClass method:(SEL)originalSelector forClass:(Class)overrideClass method:(SEL)overrideSelector { Method originalMethod = class_getInstanceMethod(originalClass, originalSelector); Method overrideMethod = class_getInstanceMethod(overrideClass, overrideSelector); if (class_addMethod(originalClass, originalSelector, method_getImplementation(overrideMethod), method_getTypeEncoding(overrideMethod))) { class_replaceMethod(originalClass, overrideSelector, method_getImplementation(originalMethod), method_getTypeEncoding(originalMethod)); } else { method_exchangeImplementations(originalMethod, overrideMethod); } } @end </code></pre> <p>The result of this is that when a label is requested, our override function is called, which calls the original function, which conveniently happens to return us a mutable NSAttributedString that we can modify in anyway we want.

Make the command you run be some type of wrapper that redirects it's own stdout and stderr to files in whatever fashion you want (i.e., your broken down directory structure) before it execs the real job.</p>15632902868 0 Swift set variable to another ViewController <p>I have two tabs.

However what you're talking about requires knowledge of one of the fundamental tennets of PHP and programming in general aka scope, namely what the global scope is.</p> <p>So, if you declare this in the global scope:</p> <pre><code> $uom = new UOM_Class(); </code></pre> <p>Then in any file afterwards you write:</p> <pre><code>global $uom; $uom->something(); </code></pre> <p>it will work.</p> <p>This is all wasteful however, instead you would be better with static methods, and something more like a singleton pattern e.g.:</p> <pre><code>UOM::Something(); </code></pre> <p>I leave it as a task for you to learn what a singleton is, and what scope is, these are fundamental tennets of PHP, and you should not claim to know PHP without knowing about scope. The best way of putting it is when in everyday conversation, it is called <em>context</em>, the global scope is tantamount to shouting in everyones ear at the same time. Everyone can access it, and its not something you want to pollute</p> <p>I'm sorry if I seem a bit harsh, here's some articles that should help, they talk about scope, singletons and some other methods of doing it, like object factories</p> <p><a href="http://php.net/manual/en/language.variables.scope.php" rel="nofollow">http://php.net/manual/en/language.variables.scope.php</a> http://www.homeandlearn.co.uk/php/php8p2.html</p> <p><a href="http://php.net/manual/en/language.oop5.patterns.php" rel="nofollow">http://php.net/manual/en/language.oop5.patterns.php</a></p>15839795421 0 Show in view only object with specified id <p>i am woking on a project about a restaurant and i need to show on my staff view only the Chef and Su-Chef which has id (Chef-2, Su-Chef 4).

You can instantiate a universally quantified hypothesis and you can instantiate an existentially quantified conclusion, but not vice versa. I'm thinking the proper name is "introduction". You can introduce existential quantification in a hypothesis and you can introduce universal quantification in the conclusion. If it seems like you're "eliminating" instead, that's because, when proving something, you start at the bottom of a sequent calculus deriviation, and work your way backwards to the top.</p> <p>Anyway, use the tactic <code>firstorder</code>. Also, use the command <code>Set Firstorder Depth 0</code> to turn off proof search if you only want to simplify your goal.</p> <p>If your goal has higher order elements though, you'll probably get an error message.

Thanks! </p>20223514209 0 <p>One of the first things you need to learn about SQL (and relational databases) is that you shouldn't store multiple values in a single field.</p> <p>You should create another table and store one value per row.</p> <p>This will make your querying easier, and your database structure better.</p> <pre><code>select case when exists (select countryname from itemcountries where yourtable.id=itemcountries.id and countryname = @country) then 'national' else 'regional' end from yourtable </code></pre>20322104970 0 <p>Looking at the source of <a href="http://www.ruby-doc.org/stdlib-2.1.1/libdoc/set/rdoc/Set.html#method-c-new" rel="nofollow"><code>Set::new</code></a>:</p> <pre><code># File set.rb, line 80 def initialize(enum = nil, &block) # :yields: o @hash ||= Hash.new enum.nil? and return if block do_with_enum(enum) { |o| add(block[o]) } else # you did not supply any block, when you called `new` # thus else part will be executed here merge(enum) end end </code></pre> <p>it seems that <code>Set.new</code> calls method <code>#add</code> internally. In the OP's example, <code>block</code> is <code>nil</code>, thus <a href="http://www.ruby-doc.org/stdlib-2.1.1/libdoc/set/rdoc/Set.html#method-i-merge" rel="nofollow"><code>#merge</code></a> is called:</p> <pre><code># File set.rb, line 351 def merge(enum) if enum.instance_of?(self.class) @hash.update(enum.instance_variable_get(:@hash)) else # in your case this else part will be executed. do_with_enum(enum) { |o| add(o) } end self end </code></pre> <p>Hence <code>add</code> is called for each element of <code>enum</code> (<code>[1,2]</code>).

Thus even if you added <code>5</code> twice, you are getting only one <code>5</code>. This is the reason you are not getting <code>#<Set: {1,2}></code>, but <code>#<Set: {5}></code>. As below, when you call <code>Set.new</code>, the object <code>#<Set: {5}></code> is created just as I explained above:</p> <pre><code>require 'set' class Set alias :old_add :add def add(arg) arg = 5 old_add arg end end s = Set.new ([1,2]) s # => #<Set: {5}> </code></pre> <p>When you called <code>s.add(3)</code>, your overridden <code>add</code> method was called, and it again passed the <code>5</code> to the old <code>add</code> method.

For example, it seems to be clear that this list includes:</p> <ul> <li><code>form_for</code></li> <li><code>form_tag</code></li> <li><code>fields_for</code></li> <li><code>field_set_tag</code></li> </ul> <p>... from <a href="https://github.com/rails/rails/commit/7b622786fcc5046a06989ec7a" rel="nofollow">7b622786f</a>,</p> <ul> <li><code>link_to</code></li> </ul> <p>... alluded to in <a href="https://github.com/rails/rails/commit/e98474096a6a514b2a5c299" rel="nofollow">e98474096</a> and:</p> <ul> <li><code>div_for</code></li> <li><code>content_tag_for</code></li> </ul> <p>... alluded to in <a href="https://github.com/rails/rails/commit/e8d2f48cff858728280eef575e95c3b82ecd69d9" rel="nofollow">e8d2f48cff</a></p> <ul> <li><code>remote_form_for</code></li> </ul> <p>.... alluded to in <a href="https://github.com/rails/rails/commit/4f0982db91f4e67b36aec7f1e7445655e7bce8ce" rel="nofollow">0982db91f</a>, although it's removed in Rails 3.</p> <p>However, I'm sure that's not complete - can anyone supply a complete list?</p>20920669873 0 <p>This cannot be done using only CSS3.

Each listener can either be a pointer to an object and a function to call, or a std::function. For example, the MenuItem object defines an OnClick event that will call a function that takes a MenuItem*:</p> <pre><code>someMenuItem->OnClick.addListener( this, &myObj.doSomeAction ); ... void myObj::doSomeAction( MenuItem* menuItem ) {} </code></pre> <p>or</p> <pre><code>someMenuItem->OnClick.addListener( []( MenuItem* menuItem ) {} ); </code></pre> <p>It's often the case that doSomeAction is part of the public API of the class that we might want to call for some reason other than the user selecting the menu item. Is it possible to use std::bind to throw away the MenuItem* argument so that <code>doSomeAction( MenuItem* menuItem )</code> could be defined as simply <code>doSomeAction()</code>?</p> <p>PS - I do realize that I could use lambdas to do the same thing, but if bind can do the same thing then it might be more stylistically pleasing to some.</p>21123350686 0 <p><a href="http://projects.spring.io/spring-social-facebook/" rel="nofollow">Spring Social Facebook</a> is a module within the <a href="http://projects.spring.io/spring-social/" rel="nofollow">Spring Social</a> family of projects that enables you to connect your <a href="http://spring.io/" rel="nofollow">Spring</a> application with the <a href="https://developers.facebook.com/docs/graph-api" rel="nofollow">Facebook Graph API</a>.</p> <h2>Features:</h2> <ul> <li>A service provider and connection factory for use with Spring Social's connection framework</li> <li>A Java API binding for Facebook's Graph API</li> <li>A real-time update controller for handling real-time update callbacks from Facebook</li> <li>A disconnect controller to handle disconnect callbacks from Facebook</li> <li>Much more...</li> </ul> <h2>More Information:</h2> <ul> <li><a href="http://projects.spring.io/spring-social-facebook/" rel="nofollow">Project Page</a></li> <li><a href="https://github.com/spring-projects/spring-social-facebook" rel="nofollow">Source (GitHub)</a></li> <li><a href="https://github.com/spring-projects/spring-social-samples" rel="nofollow">Sample Applications (GitHub)</a></li> <li><a href="http://docs.spring.io/spring-social-facebook/docs/current/apidocs/" rel="nofollow">API Documentation (Javadoc)</a></li> <li><a href="http://docs.spring.io/spring-social-facebook/docs/current/reference/htmlsingle/" rel="nofollow">Reference Documentation</a></li> <li><a href="https://jira.spring.io/browse/SOCIALFB/" rel="nofollow">Issue Tracker (JIRA)</a></li> <li><a href="http://spring.io/blog" rel="nofollow">The Spring Blog</a></li> </ul> <h2>Getting Started Guides:</h2> <ul> <li><a href="http://spring.io/guides/gs/accessing-facebook/" rel="nofollow">Accessing Facebook Data</a></li> <li><a href="http://spring.io/guides/gs/register-facebook-app/" rel="nofollow">Registering an Application with Facebook</a></li> </ul> <h2>Related Tags:</h2> <ul> <li><a href="/questions/tagged/spring-framework" class="post-tag" title="show questions tagged 'spring-framework'" rel="tag">spring-framework</a></li> <li><a href="/questions/tagged/spring-social" class="post-tag" title="show questions tagged 'spring-social'" rel="tag">spring-social</a></li> <li><a href="/questions/tagged/spring-social-twitter" class="post-tag" title="show questions tagged 'spring-social-twitter'" rel="tag">spring-social-twitter</a></li> <li><a href="/questions/tagged/spring-social-linkedin" class="post-tag" title="show questions tagged 'spring-social-linkedin'" rel="tag">spring-social-linkedin</a></li> <li><a href="/questions/tagged/facebook-oauth" class="post-tag" title="show questions tagged 'facebook-oauth'" rel="tag">facebook-oauth</a></li> <li><a href="/questions/tagged/oauth" class="post-tag" title="show questions tagged 'oauth'" rel="tag">oauth</a></li> <li><a href="/questions/tagged/oauth-2.0" class="post-tag" title="show questions tagged 'oauth-2.0'" rel="tag">oauth-2.0</a></li> </ul>21217179304 0 <p>You invoke the nextToken() method 3 times.

That could destroy the performance. See "false sharing". Considering, you probably don't have a lot of cores and therefore not a lot of threads and you say write is done only once, this is probably not going to be a significant problem though.</p> <blockquote> <ol start="3"> <li>Should I use atomic data types and will there be any significant time over head if I do?</li> </ol> </blockquote> <p>If you use locks (mutex), atomic variables are not necessary (and they do have overhead).

In which cases can you use atomics instead of locks... is more complicated and beyond the scope of this question I think.</p> <p>Given the description of your situation in the comments, it seems that no synchronization is required at all and therefore no atomics nor locks.</p> <blockquote> <ol start="4"> <li>...Would my array elements in this example be aligned, or is there some way to ensure they are?</li> </ol> </blockquote> <p>As pointed out by Arvid, you can request specific alignment using the <a href="http://en.cppreference.com/w/cpp/language/alignas" rel="nofollow">alginas</a> keyword which was introduced in c++11.

So I conclude that the syntax parser is not able to handle the DLL export spec, and that this is what's causing my indentation trouble.</p> <p>Unfortunately, I don't know how to teach the parser about my labels. Seems that this is pretty common practice, so I'm hoping there's a way around it.</p>29223893046 0 How to add timestamp to the existing mysql table <p>I am updatng my application from standard php into laravel and i am creating two new field in each of my table which is created_at and updated_at.</p> <p>The problem is both field has being set as null for the existing data.

I figured it was worth documenting it because I think it may be helpful to others who are using a platform where keeping a vocabulary this size in memory is more of a viable thing, and maybe it will be a possibility for future device models as well.</p> <p>There is no web-based tool I'm aware of like the Sphinx Knowledge Base Tool that will munge a 50,000-word plaintext corpus and return an ARPA language model. But, you can obtain an already-complete 64,000-word DMP language model (which can be used with Sphinx at the command line or in other platform implementations in the same way as an ARPA .lm file) with the following steps:</p> <ol> <li>Download this language model from the CMU speech site:</li> </ol> <p><a href="http://sourceforge.net/projects/cmusphinx/files/Acoustic%20and%20Language%20Models/US%20English%20HUB4%20Language%20Model/HUB4_trigram_lm.zip">http://sourceforge.net/projects/cmusphinx/files/Acoustic%20and%20Language%20Models/US%20English%20HUB4%20Language%20Model/HUB4_trigram_lm.zip</a></p> <p>In that folder is a file called language_model.arpaformat.DMP which will be your language model.</p> <ol> <li>Download this file from the CMU speech site, which will become your pronunciation dictionary:</li> </ol> <p><a href="https://cmusphinx.svn.sourceforge.net/svnroot/cmusphinx/trunk/pocketsphinx/model/lm/en_US/cmu07a.dic">https://cmusphinx.svn.sourceforge.net/svnroot/cmusphinx/trunk/pocketsphinx/model/lm/en_US/cmu07a.dic</a></p> <p>Convert the contents of cmu07a.dic to all uppercase letters. </p> <p>If you want, you could also trim down the pronunciation dictionary by removing any words from it which aren't found in the corpus language_model.vocabulary (this would be a regex problem). These files are intended for use with one of the Sphinx English-language acoustic models.</p> <p>If the desire to use a 50,000-word English language model is driven by the idea of doing some kind of generalized large vocabulary speech recognition and not by the need to use a very specific 50,000 words (for instance, something specialized like a medical dictionary or 50,000-entry contact list), this approach should give those results if the hardware can handle it. There are probably going to be some Sphinx or Pocketsphinx settings that will need to be changed which will optimize searches through this size of model.</p>29734835581 0 Buy Google search result data? <p>Wanted to use GoogleAPI to search the Internet and return the results in JSON.<br> Google API allows this to search within a specific website, but I could not find this to the entire web.

This means that instead of creating a new thread, an available thread is picked from the pool and returned there when the method finishes.</p> <p>The number of threads in the pool varies with the version of .NET and the OS, the number of cores etc. It can go from 25 threads per core in .NET 4 to hundreds or per core in .NET 4.5 on a server OS.</p> <p>An additional optimization for IO-bound (disk, network) tasks is that instead of using a thread, an IO completion port is used. Roughly, this is a callback from the IO stack when an IO operation (disk or network) finishes. This way the framework doesn't waste a thread waiting for an IO call to finish.</p> <p>When you start an asynchronous network operation, .NET make the network call, registers for the callback and releases the threadpool thread. When the call finishes, the framework gets notified and schedules the rest of the asynchronous method (essentially what comes after the <code>await</code> or <code>ContinueWith</code>) on a threadpool thread. </p> <p>Submitting a 100 asynchronous operations doesn't mean that 100 threads will be used nor that all 100 of them will execute in parallel. Rather, the framework will take into account the number of cores, the load and the number of available threads to execute as many of them as possible, without hurting overall performance. Waiting on the network calls may not even use a thread at all, while processing the messages themselves will execute on threadpool threads</p>33020908161 0 Special character in concatenated sql script causing error <p>I save stored procedure code as files and then execute them in several different databases.

I'm using, among others, the delegate methods <code>tokenField(tokenField: NSTokenField, representedObjectForEditingString editingString: String) -> AnyObject</code> and <code>tokenField(tokenField: NSTokenField, displayStringForRepresentedObject representedObject: AnyObject) -> String?</code> to work with represented objects. My represented objects are instances of a custom class.</p> <p>From the <a href="https://developer.apple.com/library/mac/documentation/Cocoa/Conceptual/TokenField_Guide/GetSetTokenFields/GetSetTokenFields.html#//apple_ref/doc/uid/TP40006555-CH9-SW2" rel="nofollow">Apple Documentation</a>, I know that <code>objectValue</code> can be used to access the represented objects of a <code>NSTokenView</code> as a <code>NSArray</code>:</p> <blockquote> <p>To retrieve the objects represented by the tokens in a token field, send the token field an <code>objectValue</code> message. Although this method is declared by <code>NSControl</code>, <code>NSTokenField</code> implements it to return an array of represented objects. If the token field simply contains a series of strings, <code>objectValue</code> returns an array of strings. To set the represented objects of a token field, use the <code>setObjectValue</code>: method, passing in an array of represented objects. If these objects aren’t strings, <code>NSTokenField</code> then queries its delegate for the display strings to use for each token.</p> </blockquote> <p>However, this doesn't seem to work for me. <code>let tokenArray = self.tokenField.objectValue! as! NSArray</code> does return a NSArray, but it is empty, even though the delegate method required to return a represented object has been called the appropriate amount of times before.</p> <p><code>NSTokenView</code> doesn't seem like a particularly strong tool to work with tokenization, but, lacking an alternative, I hope that you guys can help me making my implementation work.</p> <p>Thanks in advance!</p>39321929870 0 Error 410:gone (codenameone) <p>So I tried the tutorial Codenameone provided on JSON parsing, but now when i try it out it gives me a 410:gone error.</p> <p>I did google the error but didn't find anything in combination with java or codenameone and i don't really understand the meaning of this error.</p> <p>This error is not only in netbeans as i expected but even the on android it gives this error.</p> <p>Code below is the action performed after clicking the "get twitter"-button:</p> <pre><code>public void actionPerformed(ActionEvent evt) { ConnectionRequest request = new ConnectionRequest() { @Override protected void readResponse(InputStream input) throws IOException { JSONParser parser = new JSONParser(); System.out.println(parser.parse(new InputStreamReader(input))); } }; request.setUrl("http://search.twitter.com/search.json"); request.setPost(false); request.addArgument("q", "@codenameone"); NetworkManager manager = NetworkManager.getInstance(); manager.start(); manager.addToQueue(request); } }); </code></pre>39433373890 0 <p>MySQLi is not a driver for PDO.

If it's a customer table, then it's probably the customerid of 13029. However if it's a customer order table, then maybe it's the combination of CustomerId and OrderDate (and maybe not, I have placed two unique orders on the same date). You will know the answer to that based on your table's design.</p> <p>Armed with that knowledge, you will want to write a query to pull back the keys from the target table <code>SELECT CO.CustomerId, CO.OrderId FROM dbo.CustomerOrder CO</code> If you know the process only transfers data from the current year, add a filter to the above query to restrict the number of rows returned. The reason for this is memory conservation-you want SSIS to run fast, don't bring back extraneous columns or rows it will never need.</p> <p>Inside your dataflow, add a <a href="http://msdn.microsoft.com/en-us/library/ms141821.aspx" rel="nofollow">Lookup Transformation</a> with that query. You don't specify 2005, 2008 or 2012 as your SSIS version and they have different behaviours associated with the Lookup Transformation. Generally speaking, what you are looking to do is identify the unmatched rows. By definition, unmatched means they don't exist in the target database so those are the rows that are <em>new</em>. 2005 assumes every row is going to match or it errors. You will need to click the Configure Error Output... button and select "Redirect Rows". 2008+ has an option under "Specify how to handle rows with no matching entries" and there you'll want "Redirect rows to no match output."</p> <p>Now take the No match output branch (2008+) or the error output branch (2005) and plumb that into your destination.</p> <p>What this approach doesn't cover is detecting and handling when the source system reports $56.82 and the target system has $22.38 (updates). If you need to handle that, then you need to look at some change detection system. Look at Andy Leonard's <a href="http://www.sqlservercentral.com/articles/Stairway+Series/76390/" rel="nofollow">Stairway to Integration Services</a> series of articles to learn about options for detecting and handling changes.</p>39638004053 0 <pre><code>function dividedByArray(data,low,high) { for (i=low; i<=high; i++) { var passed = 0; for(var curr in data) { if(i % data[curr] === 0) { passed++; } } switch(passed) { case data.length : console.log(i + 'all_match'); break; case 0 : console.log(i) break; default: console.log(i + " one_match"); } } } </code></pre>39729969185 0 <p>Found the solution.

At least if you add another column, then you can preserve the sorting order for your items without touching your Order ID.</p> <p>On the other hand, if the Order ID is not the primary key for your table and you have a different primary key, then by all means use the Order ID as your sorting column. Make sure that you implement unique index for the sorting column so that it could enhance your db as well as application performance.</p> <p>To make your sorting a lot easier in .NET, you can use the classes in <a href="http://msdn.microsoft.com/en-us/library/system.collections.specialized.aspx" rel="nofollow noreferrer">System.Collections.Specialized Namespace</a> to sort your lists and want it for strongly-typed collections, i.e. Dictionary, OrderedDictionary, etc. because you will be using a key/value pair if you are implementing a sort order column.</p> <p>Hope this helps!</p>39926231138 0 Error in update ADT in Eclipse and IBM Worklight Studio <p>After update Android SDK I found this error message in Eclipse:</p> <blockquote> <p>This Android SDK requires Android Developer Toolkit version 23.0.0 or above.

Most likely your threads are not all calling functions to read standard input all the time, though.</p> <p>If you regularly need to read input from the user you might want to have one thread that just reads this input and then sets flags or posts events to other threads based on this input.</p> <p>If the kill character is the only thing you want or if this is just going to be used for debugging then what you probably want to do is occasionally poll for new data on standard input. You can do this either by setting up standard input as non-blocking and try to read from it occasionally. If reads return 0 characters read then no keys were pressed. This method has some problems, though. I've never used <em>stdio.h</em> functions on a <code>FILE *</code> after having set the underlying file descriptor (an int) to non-blocking, but suspect that they may act odd. You could avoid the use of the <em>stdio</em> functions and use <code>read</code> to avoid this. There is still an issue I read about once where the block/non-block flag could be changed by another process if you forked and exec-ed a new program that had access to a version of that file descriptor. I'm not sure if this is a problem on all systems. Nonblocking mode can be set or cleared with a 'fcntl' call.</p> <p>But you could use one of the polling functions with a very small (0) timeout to see if there is data ready. The <code>poll</code> system call is probably the simplest, but there is also <code>select</code>. Various operating systems have other polling functions.</p> <pre><code>#include <poll.h> ... /* return 0 if no data is available on stdin. > 0 if there is data ready < 0 if there is an error */ int poll_stdin(void) { struct pollfd pfd = { .fd = 0, .events = POLLIN }; /* Since we only ask for POLLIN we assume that that was the only thing that * the kernel would have put in pfd.revents */ return = poll(&pfd, 1, 0); } </code></pre> <p>You can call this function within one of your threads until and as long as it retuns 0 you just keep on going. When it returns a positive number then you need to read a character from stdin to see what that was. Note that if you are using the <em>stdio</em> functions on <code>stdin</code> elsewhere there could actually be other characters already buffered up in front of the new character. <code>poll</code> tells you that the operating system has something new for you, not what C's <em>stdio</em> has.</p> <p>If you are regularly reading from standard input in other threads then things just get messy. I'm assuming you aren't doing that (because if you are and it works correctly you probably wouldn't be asking this question).</p>4256659250 0 <p>protobuf.net has to maintain compatibility with the protobuf binary format, which is designed for the Java date/time datatypes.

Of course they're important but only after having taught the STL containers.</p> <p>Another important concept that new students have to get their head around is the concept of different compilation units, the One Definition Rule (because if you don't know it you won't be able to decypher error messages) and headers. This is actually quite a barrier and one that has to be breached early on.</p> <p>Apart from the language features the most important thing to be taught is how to understand the C++ compiler and how to get help.

The view controller has custom zooming behavior, so on <code>-scrollViewDidEndZooming</code> every tile needs to be redrawn. But, even though <code>-setNeedsDisplay</code> is being called on the layer after every zoom, not all tiles are being redrawn. This is causing the view to sometimes look wrong after a zoom. (Things that should appear in just 1 tile are appearing in multiple places). It often corrects itself after another zoom. </p> <p>Here's the relevant code. <code>updatedRects</code> is for testing -- it stores the unique rectangles requested to be drawn by <code>-drawLayer</code>. </p> <p>CanvasView.h: </p> <pre><code>@interface CanvasView : UIView @property (nonatomic, retain) NSMutableSet *updatedRects; @end </code></pre> <p>CanvasView.m: </p> <pre><code>@implementation CanvasView @synthesize updatedRects; + (Class)layerClass { return [CATiledLayer class]; } - (void)drawLayer:(CALayer *)layer inContext:(CGContextRef)context { CGRect rect = CGContextGetClipBoundingBox(context); [updatedRects addObject:[NSValue valueWithCGRect:rect]]; CGContextSaveGState(context); CGContextTranslateCTM(context, rect.origin.x, rect.origin.y); // ...draw into context... CGContextRestoreGState(context); } @end </code></pre> <p>MyViewController.m: </p> <pre><code>@implementation MyViewController - (void)viewDidLoad { [super viewDidLoad]; canvasView.updatedRects = [NSMutableSet set]; } - (void)scrollViewDidEndZooming:(UIScrollView *)scrollView withView:(UIView *)view atScale:(float)scale { canvasView.transform = CGAffineTransformIdentity; canvasView.frame = CGRectMake(0, 0, canvasView.frame.size.width * scale, canvasView.frame.size.height); [self updateCanvas]; } - (void)updateCanvas { NSLog(@"# rects updated: %d", [canvasView.updatedRects count]); [canvasView.updatedRects removeAllObjects]; canvasView.frame = CGRectMake(canvasView.frame.origin.x, canvasView.frame.origin.y, canvasView.frame.size.width, myHeight); CGFloat tileSize = 256; NSLog(@"next # rects updated will be: %f", [canvasView.layer bounds].size.width / tileSize); [canvasView.layer setNeedsDisplay]; } @end </code></pre> <p>When testing this, I always scrolled all the way across the view after zooming to make sure every tile was seen. Whenever the view looked wrong, the predicted "next # of rects updated" was greater than the actual "# of rects updated" on the next call to <code>-updateCanvas</code>. What would cause this? </p> <p><strong>Edit:</strong> </p> <p>Here's a better way to visualize the problem. Each time <code>updateCanvas</code> is called, I've made it change the background color for drawing tiles and record the time it was called -- the color and time are stored in <code>canvasView</code>. On each tile is drawn the tile's rectangle, the tile's index along the x axis, the time (sec.) when the background color was set, and the time (sec.) when the tile was drawn. If everything is working correctly, all tiles should be the same color. Instead, here's what I'm sometimes seeing: </p> <p><img src="https://i.stack.imgur.com/k2BjY.png" alt="Screenshot of tiles with mismatched colors"> <img src="https://i.stack.imgur.com/6GzNS.png" alt="Screenshot of tiles with mismatched colors"></p> <p>I only seem to see wrong results after zooming out. <strike>The problem might be related to the fact that <code>scrollViewDidEndZooming</code>, and therefore <code>updateCanvas</code>, can get called multiple times per zoom-out.</strike> (<strong>Edit</strong>: No-- not called multiple times.) </p>455661733 0 <p>If you are running Time Machine on Leopard (OS X 10.5) then you have a chance that the files are in the backup.

The network thread is using an external library, which has its own select() based event loop... so the network thread isn't using Qt's event system.</p> <p>At the moment, the network thread just emit()s signals when various events occur, such as a successful connection. I think this works okay, as the signals/slots mechanism posts the signals correctly for the GUI thread.</p> <p>Now, I need for the network thread to be able to call the GUI thread to ask questions. For example, the network thread may require the GUI thread to request put up a dialog, to request a password.</p> <p>Does anyone know a suitable mechanism for doing this?</p> <p>My current best idea is to have the network thread wait using a QWaitCondition, after emitting an object (<code>emit passwordRequestedEvent(passwordRequest);</code>. The passwordRequest object would have a handle on the particular QWaitCondition, and so can signal it when a decision has been made..</p> <p>Is this sort of thing sensible? or is there another option?</p>4636362068 0 <p>This website is answer to my question: <a href="http://embed.ly/" rel="nofollow">http://embed.ly/</a> :)</p>46415532242 0 error while installing WindowBuilder Pro Update Site - http://dl.google.com/eclipse/inst/d2wbpro/latest/3.7 <p>I faced this error while installing <a href="http://dl.google.com/eclipse/inst/d2wbpro/latest/3.7" rel="nofollow">http://dl.google.com/eclipse/inst/d2wbpro/latest/3.7</a> on eclipse Juno Service Release 1 </p> <pre><code>An error occurred while collecting items to be installed session context was:(profile=epp.package.jee, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).

The exercise's challenge is to read an arbitrary number of words into a vector, then output the number of times a given word appears in that input. I've included my relevant code below:</p> <pre><code>string currentWord = words[0]; words_sz currentWordCount = 1; // invariant: we have counted i of the current words in the vector for (words_sz i = 1; i < size; ++i) { if (currentWord != words[i]) { cout << currentWord << ": " << currentWordCount << endl; currentWord = words[i]; currentWordCount = 0; } ++currentWordCount; } cout << currentWord << ": " << currentWordCount << endl; </code></pre> <p>Note that the output code has to occur again outside the loop to deal with the last word. I realize I could move it to a function and simply call <em>the function</em> twice if I was worried about the complexity of duplicated code.</p> <p><strong>Question 1:</strong> Is this sort of workaround is common? Is there a typical way to refactor the loop to avoid such duplication?</p> <p><strong>Question 2:</strong> While my solution is straightforward, I'm used to counting from zero. Is there a more-acceptable way to write the loop respecting that? Or is this the optimal implementation?</p>48413754000 0 <p>Is there a reason you were using <code>Request.Form</code>?

Hence, the type <code>b -> c</code> (the first argument to <code>(.)</code>) must match the type <code>Int -> Bool</code> (the type of <code>doSomeX</code>).

My application currently makes extensive use of global variables (I carry an instance of my <code>AppDelegate</code> in every view controller to access properties I declared in my <code>AppDelegate.h</code>). Although it does what I want it to do, I've read this is not a good design practice. </p> <p>So I want to start making my code "legit". However, I can't imagine my app right now without global variables. They are so important to the well-being of the app, but this must mean I'm doing something wrong, right? I just can't imagine how else I'd do some things. Take for example this:</p> <p><img src="https://i.stack.imgur.com/DlH1e.png" alt="enter image description here"></p> <p>You have two view controllers here, a <code>SideViewController</code> and a <code>MainViewController</code>. Using global variables, such as say if the entire application had one shared instance of <code>SideViewController</code> and <code>MainViewController</code> (<code>appDelegate.sideViewController</code> and <code>appDelegate.mainViewController</code>), I can easily communicate between the two view controllers, so that if I press "News Feed" in my <code>SideViewController</code>, I can tell my <code>MainViewController</code> to reload it's view. </p> <p>I can't imagine, however, how this would be done if these were not global variables? If an event occurs in my <code>SideViewController</code>, how would I notify my <code>MainViewController</code>, in a way that is in accordance with design standards?</p>49535071799 0 Dynamically enumerate keys in libconfig <p>in <code>libconfig</code> - is it possible to dymanically enumerate keys?</p> <p>As an example, in this <a href="https://github.com/hyperrealm/libconfig/blob/master/examples/c/example.cfg" rel="nofollow">example</a> config file from their repo - if someone invented more days in the <code>hours</code> section, could the code dynamically enumerate them and print them out?</p> <p>Looking at the docs, I see lots of code to get a specific string, or list out an array, but I can't find an example where it enumerates the keys of a config section. </p> <p><strong>Edit</strong></p> <p>Received some downvotes, so thought I'd have another crack at being more specific. </p> <p>I'd like to use libconfig to track some state in my application, read in the last known state when the app starts, and write it out again when it exits. My app stores things in a tree (of depth 2) - so this could be niceley represented as an associative array in a libconfig compatible file as below. The point is that the list of Ids (<code>1234/4567</code>) can change. I could track them in another array, but if I could just enumerate the 'keys' in the <code>ids</code> array below - that would be neater.</p> <p>so </p> <pre><code>ids = { "1234" = [1,2,3] "4567" = [9,10,11,23] } </code></pre> <p>e.g (psuedocode)</p> <pre><code>foreach $key(config_get_keys_under(&configroot)){ config_get_String($key) } </code></pre> <p>I can't see anything obvious in the header file. </p>4962663579 0 <p>You probably have an ancient version of xerces on the classpath.

I'm querying an online dictionary to get translated words, however non-English characters are displayed as e.g. <code>x86</code> or <code>x84</code>. However, if I just do <code>print(the_same_non-english_character)</code> the letter is displayed in a proper form. I use Python 3.3.2 and the HTML source of the site I extract the words from has <code>charset=UTF-8</code> set. Morever, if I use e.g. <code>replace("x86", "non-english_character")</code>, I don't get anything replaced, but replacing of normal characters works.</p>50239113806 0 How to send a value in Database to Google analytics? <p>I manage web application which is made by Symfony2(PHP).

Thanks!</p>52320895184 0 Identical template for many functions <h1>Hello guys (and happy new year!)</h1> <p>I'm writing a (not really) simple project in C++ (my first, coming from plain C). I was wondering if there is a way to simplify the definition for multiple functions having the same template pattern. I think an example would be better to explain the problem.</p> <h2>The context</h2> <p>Let's assume I have a "Set" class which represents a list of numbers, defined as</p> <pre><code>template <class T> class Set { static_assert(std::is_arithmetic<T>(), "Template argument must be an arithmetic type."); T *_address; ... } </code></pre> <p>So if I have an instance (say <code>Set<double></code>) and an array <code>U array[N]</code>, where <code>U</code> is another arithmetic type and <code>N</code> is an integer, I would like to be able to perform some operations such as assigning the values of the array to those of the <code>Set</code>. Thus I create the function template inside the class</p> <pre><code>template <class U, int N> void assign(U (&s)[N]) { static_assert(std::is_arithmetic<U>(), "Template argument must be an arithmetic type."); errlog(E_BAD_ARRAY_SIZE, N == _size); idx_t i = 0; do { _address[i] = value[i]; } while (++i < size); } </code></pre> <h2>The problem</h2> <p>As far as my tests went the code above works perfectly fine. However I find it REALLY REALLY ugly to see since I need the <code>static_assert</code> to ensure that only arithmetic types are taken as arguments (parameter <code>U</code>) and I need a way to be sure about the array size (parameter <code>N</code>). Also, I'm not done with the <code>assign</code> function but I need so many other functions such as <code>add</code>, <code>multiply</code>, <code>scalar_product</code> etc. etc.!</p> <h2>The first solution</h2> <p>I was wondering then if there is a prettier way to write this kind of class. After some work I've come up with a preprocessor directive:</p> <pre><code>#define arithmetic_v(_U_, _N_, _DECL_, ...) \ template <class U, idx_t N> _DECL_ \ { \ static_assert(std::is_arithmetic<U>(),"Rvalue is not an arithmetic type."); \ errlog(E_BAD_ARRAY_SIZE, N == _size); \ __VA_ARGS__ \ } </code></pre> <p>thus defining my function as</p> <pre><code>arithmetic_v(U, N, void assign(U (&value)[N]), idx_t i = 0; do { _address[i] = value[i]; } while (++i < _size); ) </code></pre> <p>This is somehow cleaner but still isn't the best since I'm forced to lose the brackets wrapping the function's body (having to include the <code>static_assert</code> INSIDE the function itself for the template parameter <code>U</code> to be in scope).</p> <h2>The question</h2> <p>The solution I've found seems to work pretty well and the code is much more readable than before, but... Can't I use another construct allowing me to build an even cleaner definition of all the functions and still preserving the <code>static_assert</code> piece and the info about the array size? It would be really ugly to repeat the template code once for each function I need...</p> <h2>The thanks</h2> <p>I'm just trying to learn about the language, thus ANY additional information about this argument will be really appreciated. I've searched as much as I could stand but couldn't find anything (maybe I just couldn't think of the appropriate keywords to ask Google in order to find something relevant).

In fact I already showed this works at <a href="http://stackoverflow.com/questions/26358119/static-linkage-with-glibc-without-calling-main">static-linkage-with-glibc-without-calling-main</a>. That hello world code uses 32-bit absolute addressing with elf64 and runs fine.</p> <p>@HristoIliev suggested using rip relative addressing but did not explain that 32-bit absolute addressing in Linux would work as well. In fact if you change <code>lea rdi, [rel msg]</code> to <code>lea rdi, [msg]</code> it assembles and runs fine with <code>nasm -efl64</code> but fails with <code>nasm -macho64</code></p> <p>Like this:</p> <pre><code>section .data msg db 'This is a test', 10, 0 ; something stupid here section .text global _main extern _printf _main: push rbp mov rbp, rsp xor al, al lea rdi, [msg] call _printf mov rsp, rbp pop rbp ret </code></pre> <p>You can check that this is an absolute 32-bit address and not rip relative with <code>objdump</code>. However, it's important to point out that the preferred method is still rip relative addressing. Agner in the same manual writes:</p> <blockquote> <p>There is absolutely no reason to use absolute addresses for simple memory operands. Rip- relative addresses make instructions shorter, they eliminate the need for relocation at load time, and they are safe to use in all systems.</p> </blockquote> <p>So when would use use 32-bit absolute addresses in 64-bit mode? Static arrays is a good candidate. See the following subsection <em>Addressing static arrays in 64 bit mode</em>. The simple case would be e.g:</p> <pre><code>mov eax, [A+rcx*4] </code></pre> <p>where A is the absolute 32-bit address of the static array. This works fine with Linux but once again you can't do this with Mac OS X because the image base is larger than 2^32 by default. To to this on Mac OS X see example 3.11c and 3.11d in Agner's manual. In example 3.11c you could do</p> <pre><code>mov eax, [(imagerel A) + rbx + rcx*4] </code></pre> <p>Where you use the extern reference from Mach O <code>__mh_execute_header</code> to get the image base. In example 3.11c you use rip relative addressing and load the address like this</p> <pre><code>lea rbx, [rel A]; rel tells nasm to do [rip + A] mov eax, [rbx + 4*rcx] ; A[i] </code></pre>5331315826 0 Sharing objects between C# and C++ code <p>Is it possible to share references to C# objects between C# and C++ code without massive complexity?

The card number is comprised of a 6 digit Issuer Identification Number (IIN), an account number and a luhn check digit. The IIN ranges are constantly changing and industry sectors that rely on this information (such as Payment Processors) will generally be updated as changes occur. It's reasonably safe to assume that the card number should be between 16 and 19 digits, and start with 3, 4, 5 or 6. Beyond that trying to identify the card type from the IIN is prone to error unless you are frequently updated.</p></li> <li><p><strong>Luhn / Mod10 check digit</strong>.<br> The last digit of the card number is a check digit to pick up transposition errors which may have occured when an operator has keyed in the card number. The <a href="http://en.wikipedia.org/wiki/Luhn_algorithm">wikipedia article</a> is a good source for more info and code samples.</p></li> <li><p><strong>Magnetic stripe</strong><br> If you have physical access to the card, and a magstripe reader, then track 2 contains banking card info. Amongst the details are card number, expiry date, LRC (check digit) and a Service Code. The service code (only available on mag stripe) informs how the card may be used, eg only for national payments, only for use at an ATM (not as a payment card), whether cash back should be offered etc.</p></li> <li><p><strong>CCV / CSC / CV2</strong><br> Security digits are never embossed onto the card, or recorded on the magstripe. Should be three digits on all except Amex (always 4 digits)</p></li> <li><p><strong>Issue date</strong><br> Used for manual (sanity) check only. Not sent during the authorization request</p></li> <li><p><strong>Expiry date</strong><br> A common misconception is that expired cards cannot be used. They frequently can, but they must go through online authorization first (so that the acquiring bank has final say on whether it is permitted or not). Expiry dates can be up to 20 years in the future (and even further in some rare cases)</p></li> <li><p><strong>Issue number</strong><br> Only available on certain card types.

Make sure these match!)</p> <p>You're correct in thinking that you're creating a new instance of <code>mainViewController</code>. To get at the one you want, You'll either need to pass a reference to <code>mainViewController</code> into the new view controller when you create it, writing a method like:</p> <pre><code>@synthesize mainViewController; -(void) initWithMainVC:(MainViewController *)mainVC { if ((self = [super init])) { self.mainViewController = mainVC; } return self; } </code></pre> <p>to override <code>init</code>, or, if you've got a reference to <code>mainViewController</code> in your App Delegate, you can get it using:</p> <pre><code>MainViewController *mainVC = [(YourAppDelegate *)[[UIApplication sharedApplication] delegate] mainViewController]; </code></pre> <p>Either way you choose, you'll want to read up on object oriented programming and pointers in objective C. When you call <code>alloc</code>, you're manufacturing a new copy of that class. All copies sit in different chunks of memory, so any new one you make (as in your code above) is actually a totally different entity, like two Priuses, or something like that.</p> <p>A pointer is like a nametag that identifies, or points the way, to that block of memory. In my <code>init</code> code example above, we're attaching a new nametag to a <code>mainViewController</code> instance with the same guts. Same thing with the second line -- we make a new pointer (see the star?) tell it it's going to be pointing to a <code>MainViewController</code> instance, and slap that nametag, or pointer, on to an instance.</p> <p>(The second one is a little more complicated, as you're plucking <code>mainViewController</code> from an object called a singleton, or an object that you can get at from anywhere... read more about those and the App Delegate at <a href="http://cocoawithlove.com/2008/11/singletons-appdelegates-and-top-level.html" rel="nofollow">this post</a> from Cocoa with Love.)</p> <p>Anyway, I get nervous expounding on this stuff on Stack!

Doing that suggests that all your versions of info.plist are almost identical, except for a couple of differences. That's a recipe for divergence, and then hard-to-debug issues when you want to add a new URI handler or background mode or any of the other things that might modify info.plist.</p> <p>Instead, I recommend you take the keys that vary out of the main info.plist. Create another plist (say "Config.plist") to store them. Add a Run Script build phase to copy the correct one over. See the <a href="https://developer.apple.com/library/ios/documentation/DeveloperTools/Reference/XcodeBuildSettingRef/1-Build_Setting_Reference/build_setting_ref.html" rel="nofollow">Build Settings Reference</a> for a list of variables you can substitute.

I personally generally use the preprocessor for this kind of problem. In my build configuration, I would set <code>GCC_PREPROCESSOR_DEFINITIONS</code> to include <code>BaseURL=...</code> for each build configuration and then in some header I would have:</p> <pre><code>#ifndef BaseURL #define BaseURL @"http://default.example.com" #endif </code></pre> <p>The plist way is probably clearer and easier if you have several things to set, especially if they're long or complicated (and definitely if they would need quoting). The preprocessor solution takes less code to process and has fewer failure modes (since the strings are embedded in the binary at compile time rather than read at runtime).

It does them, fancily, in one line, by using +clone and the parentheses. It's less confusing to do it as two commmands though:</p> <pre><code>convert thumbnail.gif \ -alpha extract \ -virtual-pixel black \ -spread 10 \ -blur 0x3 \ -threshold 50% \ -spread 1 \ -blur 0x.7 \ mask.png convert thumbnail.gif mask.png \ -alpha off \ -compose Copy_Opacity \ -composite torn_paper.png </code></pre> <p>The first command is fairly complex. But you can find decent explanations of each of the component commands in the ImageMagick docs:</p> <ul> <li><a href="http://www.imagemagick.org/Usage/masking/#alpha_extract" rel="nofollow">http://www.imagemagick.org/Usage/masking/#alpha_extract</a></li> <li><a href="http://www.imagemagick.org/Usage/misc/#virtual_examples" rel="nofollow">http://www.imagemagick.org/Usage/misc/#virtual_examples</a></li> <li><a href="http://www.imagemagick.org/script/command-line-options.php#blur" rel="nofollow">http://www.imagemagick.org/script/command-line-options.php#blur</a></li> </ul> <p>Also, by splitting the command into these two pieces, you can see what the mask looks like on its own. It's basically the inverse of the paper effect. White throughout the middle of the images, fading to black around the "torn edges". </p> <p>The second command is a lot more straightforward. Copy_Opacity, as described in the <a href="http://www.imagemagick.org/Usage/compose/#copyopacity" rel="nofollow">ImageMagick docs</a>, is a way of making parts of an image transparent or not. Anything that's black in the mask will be made transparent in the resulting image. In effect, the second command uses the mask to "erase" the edges of the original thumbnail in a stylistically interesting way.</p>63718597835 0 Placing a TextView below two ImageViews and in middle - Android <p>Please share code to achieve the layout of the screen shown in the below link.

A couple of extra warnings are needed.</p> <p>A scan (or the scan time) can be shorter than your code's execution time. In most PLC's there is a "watchdog" to detect this, and warn you that it is happening. You often need to set this "watchdog" up, and set up a alarm/event handler for it.</p> <p>Know how your PLC executes I/O. Some (Such as ControlLogix) are Asynchronous, I/O gets read into your controllers memory based on the RPI (request packet interval), and gets written out (same RPI) when you make a change to the I/O point with code. Others (Such as AutomationDirect's Productivity 2000 series) only write the outputs upon a COMPLETE scan of your code. I'm sure you can picture the pro's and cons of each scenario, especially if your controller is not completing your code before restarting a scan.</p> <p>PLC's that allow you to have different scan rates for different pieces of code give you powerful tools for I/O and program flow management. Slow processes can be scanned slowly, allowing you more PLC time for other things.</p>6399814937 0 <p>Follow this guide: <a href="http://weblogs.asp.net/psheriff/archive/2009/12/01/load-resource-dictionaries-at-runtime-in-wpf.aspx" rel="nofollow">http://weblogs.asp.net/psheriff/archive/2009/12/01/load-resource-dictionaries-at-runtime-in-wpf.aspx</a></p> <ol> <li>Create various xaml resource files, but make sure the file does not compile and copies into the bin directory instead.</li> <li>Decorate your xaml controls with <code>DynamicResource</code>s.</li> <li>Load in your resources through code.</li> </ol> <p>Basically, you are looking to "skin" your application.

You create a <code>weakref</code> with <code>weakref.ref(printfunc)</code>, but you follow it up with call parens, which converts back from <code>weakref</code> to a strong ref which you store (and the <code>weakref</code> object promptly disappears). Apparently it's not possible to store a <code>weakref</code> to the bound method itself (because the bound method is its own object created each time it's referenced on <code>self</code>, not a cached object whose lifetime is tied to <code>self</code>), so you have to get a bit hacky, unbinding the method so you can take a <code>weakref</code> on the object itself. Python 3.4 introduced <a href="https://docs.python.org/3/library/weakref.html#weakref.WeakMethod" rel="nofollow"><code>WeakMethod</code></a> to simplify this, but if you can't use that, then you're stuck doing it by hand.</p> <p>Try changing it to (on Python 2.7, and you must <code>import inspect</code>):</p> <pre><code># Must special case printfunc=None, since None is not weakref-able if printfunc is None: # Nothing provided self.printobjref = self.printfuncref = None elif inspect.ismethod(printfunc) and printfunc.im_self is not None: # Handling bound method self.printobjref = weakref.ref(printfunc.im_self) self.printfuncref = weakref.ref(printfunc.im_func) else: self.printobjref = None self.printfuncref = weakref.ref(printfunc) </code></pre> <p>and change <code>myprint</code> to:</p> <pre><code>def myprint(self,text): if self.printfuncref is not None: printfunc = self.printfuncref() if printfunc is None: self.printfuncref = self.printobjref = None # Ref died, so clear it to avoid rechecking later elif self.printobjref is not None: # Bound method not known to have disappeared printobj = self.printobjref() if printobj is not None: print ("ExtenalFUNC:%s" %text) # To call it instead of just saying you have it, do printfunc(printobj, text) return self.printobjref = self.printfuncref = None # Ref died, so clear it to avoid rechecking later else: print ("ExtenalFUNC:%s" %text) # To call it instead of just saying you have it, do printfunc(text) return print ("JustPrint:%s" %text) </code></pre> <p>Yeah, it's ugly.

If both are successful, then it's time to start looking inside your software for clues.</p></li> </ol> <p>If you still can't untangle what is happening, please include the output of the aforementioned commands when you come back... as well as how you're starting the <code>ppp</code> connection.</p>6624521403 0 How to ad a title on a section of my wordpress blog <p>I want to ad a title "Instant Independent" to the center "featured" section of my wordpress blog.

When updating the extension there are errors as the files are unable to overwrite the existing directories. I mainly noticed this due to the icons being missing from the Magento admin panel. Although baffling, no big deal, I deleted the directories (x4) and copied the correct files from the original distribution. Problem solved.</p> <p>I used find . -type d "<em>.</em>" and also the 'empty' option to identify directories which should be files. This fixes the symptom but not the cause. There were around 10 files, mostly images but some .js and .css affected.</p> <p>I've just run an update of M2e via Magento connect, 'successfully', but having noticed some missing icons/graphics in admin I checked the code and have identified 17 empty directories that should have been image files (.png and .gif).</p> <p>I guess my questions are how and why is this happening? How can I stop it happening again?</p> <p>I have a dedicated CentOS server running Apache. Installs are done via Filezilla FTP upload or Magento Connect, it seems most likely that it's Connect causing the problem, both extensions have been updated by Connect at least once in their lifetime.</p> <p>Hoping someone can enlighten me, though not a huge problem in itself, it is a concern that critical files (rather than images) may be prone to the same problems...Anyone seen this before??</p> <p>Cheers RobH</p>6753294365 0 <p>The destination anchor for a link in an HTML page may be any element with an <code>id</code> attribute.

You should rather use the available build in functions on them as they are optimized and in many cases actually not written in python but in a compiled language.

But let me try to illustrate how this might work with some code.</p> <p>For simplicity, let's say you are modelling a particle system, where each particle moves accordingly to it's velocity.</p> <p>Your model comprises of a set of particles that are updated and then rendered to the screen each frame.</p> <p>In C#, your model implementation might look like this:</p> <pre><code>public class Model { public class Particle { public double X { get; set; } public double Y { get; set; } public double Vx { get; set; } public double Vy { get; set; } } public Model() { this.particles = /* ... initialize a set of particles ... */ } public void Update() { foreach (var p in this.particles) { p.X += p.Vx; p.Y += p.Vy; } } public void Render() { /* ... clear video buffer, init something, etc ... */ foreach (var p in this.particles) { this.RenderParticle(p); } } } </code></pre> <p>Pretty straightforward. As you can see, each frame we go over entire set of particles and update coordinates of each one according to it's velocity.</p> <p>Now, if the particle was immutable, there'd be no way to change it's properties, but as been said, we just create a new one with updated values. But hold on a second, doesn't that mean we'd have to replace the original particle object with an updated one in our set? Yes it does. And doesn't that mean that the <strong>set</strong> now has to be <strong>mutable</strong>? Looks like we just transfered the mutability from one place to another...</p> <p>Well, we could refactor to rebuild the entire set of particles each frame. But then, the property that stores the set would have to be mutable... Hmmm. Do you follow?</p> <p>It appears that at some point you'll have to lose immutability in order to cause effects, and depending on <em>where</em> that point is, your program will or will not have some (arguably) useful properties.</p> <p>In our case (we're making a video game), we technically can postpone the mutability all the way until we get to drawing on the screen. It's good that the screen is mutable, otherwise we'd have to create a new display each frame :)</p> <p>Now, let's see how this could be implemented in F#:</p> <pre><code>type Particle = { X : double Y : double Vx : double Vy : double } type Model = { Particles : Particle seq } module Game = let update model = let updateParticle p = { p with X = p.X + p.Vx; Y = p.Y + p.Vy } { model with Particles = seq { for p in model.Particles do yield updateParticle p } } let render model = for p in model.Particles do Graphics.drawParticle p </code></pre> <p>Note that in order to preserve immutability, we had to make the <code>Update</code> method a function that takes a model object and returns it updated. The <code>Render</code> now also takes the model object as an argument, as we don't keep it in memory anymore because it is immutable.</p> <p>Hope this helps!</p>70930605081 0 <p>OK the answer to my 2 questions are: Yes and No.</p> <p>I <strong><em>was</em></strong> missing something and there is <strong><em>nothing</em></strong> wrong with my approach.</p> <p>What was worrying me was that the instantiate approach might be causing the problem as it isn't the method described in the documentation. It turns out that this was not the problem.</p> <p>What was the problem was lazy copying and pasting. When I copied the tracking code from the GA website I accidentally also copied the line below.

The most likely problem is that it's being built incorrectly, but to address this we need to see your Makefile.</p> <p>At the link below (wouldn't let me post the link so you have to copy/paste it yourself) is a post by someone who had a very similar problem to yours. It turned out that he was not running his compiled object file through the linker, with the result that some essential library was missing which caused the PIC to loop endlessly, trying to execute an invalid opcode (instruction).</p> <p>efreedom dot com/Question/E-27081/Using-Avr-Gcc-Delay-Ms-Causes-Chip-Freeze</p> <p>If this doesn't fix it, try posting your Makefile.</p> <p>Also, there is no reason to call _delay_ms(10) 100 times, you can just call _delay_ms(1000) directly. It will use a lower resolution.</p> <p><strong>Edit:</strong> After seeing your Makefile it looks like your clock speed might be set incorrectly. The CLOCK setting specifies what speed you are running your AVR at, if it's set to something way off (like 8MHz and your PIC is running at 1MHz), the delay loop will take 8 seconds when you expect it to take one - if that's the problem your LED's will appear frozen but if you wait long enough they will actually change. Try removing the -DF_CPU=$(CLOCK) statement and see if it makes a difference.</p> <p>Apart from that your Makefile has a lot of unused/unnecessary stuff, and since I don't have a working avr-gcc setup at the moment, it's hard to follow, so it will help if you try simplifying the Makefile like the following, and see if it works - it will be close, please comment below if you get any problems!</p> <pre><code>DEVICE = attiny2313 CLOCK = 8000000 OBJECTS = main.o # Tune the lines below only if you know what you are doing: AVRDUDE = avrdude $(PROGRAMMER) -p $(DEVICE) COMPILE = avr-gcc -Wall -Os -DF_CPU=$(CLOCK) -mmcu=$(DEVICE) # symbolic targets: all: main.hex flash: all $(AVRDUDE) -U flash:w:main.hex:i clean: rm -f main.hex main.elf $(OBJECTS) main.elf: $(OBJECTS) $(COMPILE) -o main.elf $(OBJECTS) main.hex: main.elf rm -f main.hex avr-objcopy -j .text -j .data -O ihex main.elf main.hex avr-size --format=avr --mcu=$(DEVICE) main.elf </code></pre>72923849929 0 how to make uitextview scroll in iOS Storyboards <p>I have a uitextview with more text that can fit in the view.

In my case, this meant finding businesses that were in the user's location, and then only showing Business Posts near the user's location, where in the "BusinessPost" class, the key "Business" is a pointer to my "Business" class, that contains other information about the business that the UI needed. The query would look as follows: </p> <pre><code>override func queryForTable() -> PFQuery! { var getPosts = PFQuery(className: self.parseClassName) var getBusinesses = PFQuery(className: "Businesses") if locationUpdated == false { return nil } else { getBusinesses.whereKey("City", equalTo: self.city) getBusinesses.whereKey("State", equalTo: self.state) getPosts.whereKey("Business", matchesQuery: getBusinesses) getPosts.includeKey("Business") self.tableView.hidden = false self.tableView.reloadData() return getPosts } </code></pre> <p>Hope this can help others that are looking to accomplish a similar query with Parse and Swift. </p>74024622604 0 <pre><code>$('td:first-child').after('&lt;td&gt;new cell&lt;/td&gt;'); </code></pre>7419245224 0 <p>What you are looking for is a <a href="http://stackoverflow.com/questions/211383/which-method-of-clearfix-is-best">clearfix</a> so that your elements will load properly.

If it fails to compile due to some library not found, install the required packages on your system. The Ubuntu package search linked above may be useful.</li> <li>Once <code>make</code> runs successfully, it will create a brand new <code>libqsqlmysql.so</code>.

I'll put the thought process in comments.</p> <p><strong>First get a nice vertical layout going...</strong></p> <pre><code>// I'm just using standard padding to make it easier to read. // Also, I'd avoid the variable padding stuff. Just set it to a fixed value. // i.e. ==padding not (>=0, <=padding). That's confusing to read and ambiguous. @"V:|-[titleLabel]-[ratingBubbleView]-[descriptionLabel]-|" </code></pre> <p><strong>Then go through layer by layer adding horizontal constraints...</strong></p> <pre><code>// constraint the trailing edge too. You never know if you'll get a stupidly // long title. You want to stop it colliding with the end of the screen. // use >= here. The label will try to take it's intrinsic content size // i.e. the smallest size to fit the text. Until it can't and then it will // break it's content size to keep your >= constraint. @"|-[titleLabel]->=20-|" // when adding this you need the option "NSLayoutFormatAlignAllBottom". @"|-[ratingBubbleView]-[dateLabel]->=20-|" @"|-[descriptionLabel]-|" </code></pre> <p>Try not to "over constrain" your view. In your code you are constraining the same views with multiple constraints (like descriptionLabel to the bottom of the superview).</p> <p>Once they're defined they don't need to be defined again.</p> <p>Again, with the padding. Just use <code>padding</code> rather than <code>>=padding</code>. Does >=20 mean 20, 21.5, or 320? The inequality is ambiguous when laying out.</p> <p>Also, In my constraints I have used the layout option to constrain the vertical axis of the date label to the rating view. i.e. "Stay in line vertically with the rating view". Instead of constraining against the title label and stuff... This means I only need to define the position of that line of UI once.</p>8322846831 0 <p>An alternative to filtering would be to maintain the list of selected users.

It's extremely unlikely that you previously allocated some memory that happeneds to start at 0x10, even in the crazy world of virutal address spaces. Furthermore, IF malloc failed, no memory has been allocated, so you do not need to free it.</p> <pre><code>int* memory = NULL; memory = malloc(sizeof(int)); if (memory != NULL) { memory=10; } free(memory); </code></pre> <p>This is also a bug. If malloc fails, then you are setting the pointer to 10 and freeing that memory. (as before.) If malloc succeeds, then you're immediately freeing the memory, which means it was pointless to allocate it! Now, I imagine this is just example code simplified to get the point across, and that this isn't present in your real program? :)</p>83716783675 0 Running Continumm Standalone <p>I have downloaded apache continuum. </p> <p>After that i unpacked and i typed continuun console. </p> <p>It´s started fine... but when i put localhost:8080/continuum in the browser the console show this error: What´s happend?</p> <pre><code>jvm 1 | org.apache.jasper.JasperException: PWC6345: There is an error in invo king javac.

This is expected, as there is no way for the Copy task to figure out what part of each item's path needs to be replaced with the DestinationFolder in order to keep the tree structure. For example, if your SourceDir collection is defined like this:</p> <pre><code><ItemGroup> <SourceDir Include="$(Source)\**\*" /> <SourceDir Include="E:\ExternalDependencies\**\*" /> <SourceDir Include="\\sharedlibraries\gdiplus\*.h" /> </ItemGroup> </code></pre> <p>What would you expect the destination folder tree look like?</p> <p>To preserve the tree, you need to do identity transformation and generate one destination item for each item in the SourceFiles collection. Here's an example:</p> <pre><code><Copy SourceFiles="@(Compile)" DestinationFiles="@(Compile->'$(DropPath)%(Identity)')" /> </code></pre> <p>The Copy task will take the each item in the SourceFiles collection, and will transform its path by replacing the part before the ** in the source item specification with $(DropPath).</p> <p>One could argue that the DestinationFolder property should have been written as a shortcut to the following transformation:</p> <pre><code><Copy SourceFiles="@(Compile)" DestinationFiles="@(Compile->'$(DestinationFolder)%(Identity)')" /> </code></pre> <p>Alas, that would prevent the deep copy to flat folder scenario that you are trying to avoid, but other people might using in their build process.</p>8653500096 0 Lost transaction with JPA unique constraint? <p>I have a field with an unique constraint:</p> <pre><code>@Column(unique=true) private String uriTitle; </code></pre> <p>When I try to save two entities with the same value, I get an exception - but another exception than I exected:</p> <pre><code>java.lang.IllegalStateException: <|Exception Description: No transaction is currently active at org.eclipse.persistence.internal.jpa.transaction.EntityTransactionImpl.rollback(EntityTransactionImpl.java:122) at com.example.persistence.TransactionFilter.doFilter(TransactionFilter.java:35) </code></pre> <p>The questionable filter method looks like this:</p> <pre><code>public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { EntityManager entityManager = ThreadLocalEntityManager.get(); EntityTransaction transaction = entityManager.getTransaction(); transaction.begin(); try { chain.doFilter(request, response); transaction.commit(); } catch (Throwable t) { transaction.rollback(); // line 35, mentioned in the exception throw new RuntimeException(t); } finally { entityManager.close(); ThreadLocalEntityManager.reset(); } } </code></pre> <p>... and the ThreadLocalEntityManager like this:</p> <pre><code>public class ThreadLocalEntityManager { private static EntityManagerFactory entityManagerFactory = null; private static final ThreadLocal<EntityManager> entityManager = new ThreadLocal<EntityManager>() { @Override protected EntityManager initialValue() { return entityManagerFactory.createEntityManager(); } }; private ThreadLocalEntityManager() {} public static synchronized void init(String persistenceUnit) { requireNotNull(persistenceUnit); requireState(entityManagerFactory == null, "'init' can be called only " + "once."); entityManagerFactory = Persistence.createEntityManagerFactory(persistenceUnit); } public static EntityManager get() { requireState(entityManagerFactory != null, "Call 'init' before calling " + "'get'"); return entityManager.get(); } public static void reset() { entityManager.remove(); } } </code></pre> <p>I wrapped the call to <code>save</code> with <code>try ...catch</code> to handle the unique constraint violation, but that doesn't work:</p> <pre><code>try { ThreadLocalEntityManager.get().persist(article); // article is constrained } catch(Throwable t) { t.printStackTrace(); } </code></pre> <p>Any idea why there is no transaction?

So we do the work in a background-queue so your main-queue can update the UI.</p> <p><strong>In detail:</strong> You call <code>dispatch_async</code> (from GrandCentralDispatch) which creates a new queue with the priority <code>QOS_CLASS_USER_INITIATED</code> (~normal priority). Then it passes the code in the curly braces to this queue; the OS will execute the queue in a separate thread. Because the UI must only be modified from the main-queue, we pass the code that updates the UI (<code>SwiftSpinner.show("Saving calendar", animated: false)</code>) to the main-queue by using <code>dispatch_async</code> again.</p> <p>The use of a completion-function is necessary because the code/queue is executed in the background and independently from <code>getOrCreateCalendar</code>; your function probably returns before the queue is completed and the calendar created and saved.</p>98625765221 0 What is the point of splitting up a project into 2 separate projects? <p>A lot of times I see people splitting up a Project into 2 separate projects, like in this screenshot: </p> <p><img src="https://i.stack.imgur.com/Xvgkl.png" alt="enter image description here"></p> <p>What is the point of seperating Ingot and IngotAPI instead of putting them both in the same project because they get compiled together anyways?</p>98715133470 0 <p>You can have 6 unique games between 4 teams.

For example a SaaS platform that simply uses database partitioning is already less secure as a simple SQL error could expose client data.</p> <p>I've already started looking into using different database usernames & passwords, but it does add to the complexity of the SaaS platform, and keeping things simple is always a good idea.</p> <p>Thanks!</p> <hr> <p>I have decided to go with different usernames and password for each instance.</p> <p>This is another layer of security and that cannot hurt.</p>10297180829 0 Generate Multiples XML with PHP <p>I have a PHP script that is generating an XML file.

To clarify, each <strong>sample</strong> covariance matrix is constructed from a <strong>finite</strong> number of vector snapshots (afflicted with random white Gaussian noise). Then, over a <strong>large</strong> number of trials, a large number of such matrices are generated and eigendecomposed in order to estimate the <strong>theoretical</strong> statistics of the eigenvalues.</p> <p>According to several sources (see, for example, [1, Eq.3] and [2, Eq.11]), the variance of each <strong>sample</strong> eigenvalue should be equal to that <strong>theoretical</strong> eigenvalue squared, divided by the number of vector snapshots used for each covariance matrix. However, the results I get from Matlab aren't even close.</p> <p>Is this an issue with my code? With Matlab? (I've never had such trouble working on similar problems).</p> <p>Here's a very simple example:</p> <pre><code>% Data vector length Lvec = 5; % Number of snapshots per sample covariance matrix N = 200; % Number of simulation trials Ntrials = 10000; % Noise variance sigma2 = 10; % Theoretical covariance matrix Rnn_th = sigma2*eye(Lvec); % Theoretical eigenvalues (should all be sigma2) lambda_th = sort(eig(Rnn_th),'descend'); lambda = zeros(Lvec,Ntrials); for trial = 1:Ntrials % Generate new (complex) white Gaussian noise data n = sqrt(sigma2/2)*(randn(Lvec,N) + 1j*randn(Lvec,N)); % Sample covariance matrix Rnn = n*n'/N; % Save sample eigenvalues lambda(:,trial) = sort(eig(Rnn),'descend'); end % Estimated eigenvalue covariance matrix b = lambda - lambda_th(:,ones(1,Ntrials)); Rbb = b*b'/Ntrials % Predicted (approximate) theoretical result Rbb_th_approx = diag(lambda_th.^2/N) </code></pre> <p>References:</p> <p>[1] Friedlander, B.; Weiss, A.J.; , "<a href="http://www.scribd.com/doc/112067632" rel="nofollow">On the second-order statistics of the eigenvectors of sample covariance matrices</a>," Signal Processing, IEEE Transactions on , vol.46, no.11, pp.3136-3139, Nov 1998 [2] Kaveh, M.; Barabell, A.; , "<a href="http://www.scribd.com/doc/112046406/Kaveh-86" rel="nofollow">The statistical performance of the MUSIC and the minimum-norm algorithms in resolving plane waves in noise</a>," Acoustics, Speech and Signal Processing, IEEE Transactions on , vol.34, no.2, pp. 331- 341, Apr 1986</p>10393879203 0 Tab focus granting event <p>I need to capture tab focus granting event in Firefox browser.

Maybe just add a class to the relevant elements.</p></li> <li><p>Use a javascript polyfill such a <a href="https://code.google.com/p/ie7-js/" rel="nofollow">IE9.js</a> or <a href="http://selectivizr.com/" rel="nofollow">Selectivizr</a>, which back-ports the <code>nth-child()</code> selector (and others) to IE8.</p></li> <li><p>Use jQuery or a similar library that supports <code>nth-child()</code> to set the styles rather than doing it in CSS.</p></li> <li><p>Drop support for IE8.</p></li> </ol> <p>Which of those options you decide to use will depend on what matters to you.</p> <p>If you've got code that works in other browsers and you need it to work in IE8 with the least amount of additional work, then I would suggest trying out the Selectivizr library. Or IE9.js. But I'd suggest trying Selectivizr first, as IE9.js does a lot of other stuff to the browser that may or may not affect your site.</p> <p>If you don't want to have to use a Javascript library for this but you still need IE8 support, then you'll need to take option 1, and refactor your code. That may or may not be a lot of work, depending how your code is structured and how much code there is. Bit of a shame to have to make a backward step when the CSS is there.</p> <p>Option 4 sounds like the worst option, but might be more suitable than it sounds. If the <code>nth-child</code> styling is being used for something like zebra striping, it may not be the end of the world for IE8 users just to not get the stripes. If everything else in the site works okay, they may not even miss it. And if they do miss it, you can tell them to upgrade their browser.</p>106112927929 0 Sorting the report in birt <p>I have created a column binding in a report(datetime column) using birt.

If you're ok with that, there's a ShellCmdPost autocmd you can attach to to load information. You can use that in association with an alias that writes the $CWD to a file to load the required directory and change to it.</p> <p>In your .bashrc:</p> <pre><code>alias fgv="echo $PWD > ~/.cwd; exit" </code></pre> <p>In your .vimrc:</p> <pre><code>autocmd ShellCmdPost * call LoadCWD() function! LoadCWD() let lines = readfile('~/.cwd') if len(lines) > 0 let cwd = lines[0] execute 'cd' cwd endif endfunction </code></pre> <p>Looking through the list of autocommands, I was not able to find any that detect when Vim has been suspended and has just been resumed. You could remap ctrl-z to first set a flag variable then do an unmapped ctrl-z. Then write a shell script like before that writes its $CWD to a specific file. Then you can set up an autocmd to watch that file for modification and in the handler, check the flag variable, and if it's set, reset it, read the file, and change to that directory. A bit complex, but it would work.</p> <p>That would look like this. You'll have to load the file when you start Vim so that it can monitor it for changes. You may want to <code>set hidden</code> so that you can keep the buffer open but hide it.</p> <p>In your .bashrc:</p> <pre><code>alias fg="echo $PWD > ~/.cwd; fg" </code></pre> <p>In your .vimrc:</p> <pre><code>set hidden edit ~/.cwd enew nnoremap <C-Z> :let g:load_cwd = 1<CR><C-Z> autocmd FileChangedShell ~/.cwd call LoadCWD() function!

Your email already exists in our system.

Maybe the try statement isn't failing but succeeding because SQLAlchemy is raising the exception itself and Pyramid is generating the view so the <code>except IntegrityError:</code> never gets activated. Or, more likely, I'm catching this error completely wrong.</p>10826592841 0 <p>An alternative approach is to just add a few forwarding functions:</p> <pre><code>T numberedFunction( unsigned int i ) { ... } T single() { return numberedFunction(1); } T halfDozen() { return numberedFunction(6); } </code></pre>108320520733 0 CSS code a:visited does not work <p>I have a pretty noob problem, so I hope someone could help me out.</p> <p>I have a Blogger blog, and I can't get the links to function like I want to.</p> <p>I want the links in the post content and in the sidebar - the ones that are a purple shade (#8B7083) and underlined - to look the same for both a:link and a:visited.

For example, if a I serialize an object over the wire (perhaps I send it from a client to a server via RMI), and then do it again (in separate RMI calls), then the 2 deserialized objects on the server will <em>not</em> be ==.</p> <p>However, in a "single serialization" e.g. a single client-server message which is a graph containing the same object multiple times then upon deserialization, identity <em>is</em> preserved. </p> <p>For the first case, you can, however, provide an implementation of the <a href="http://docs.oracle.com/javase/7/docs/platform/serialization/spec/input.html#5903" rel="nofollow noreferrer"><code>readResolve</code></a> method in order to ensure that the correct instance is returned (e.g. in the <em>typesafe enum</em> pattern). <code>readResolve</code> is a private method which will be called by the JVM on a de-serialized Java object, giving the object the chance to return a different instance. For example, this is how the <code>TimeUnit</code> <code>enum</code> may have been implemented before <code>enum</code>'s were added to the language:</p> <pre><code>public class TimeUnit extends Serializable { private int id; public TimeUnit(int i) { id = i; } public static TimeUnit SECONDS = new TimeUnit(0); //Implement method and return the relevant static Instance private Object readResolve() throws ObjectStreamException { if (id == 0) return SECONDS; else return this; } } </code></pre> <p>.</p>112529765240 0 If without else not running <p>I have a little code for testing a sprite, that I want to move with the mouse.

Hopefully this question is different and updated to Python <em>2.6</em> and <em>3.0</em>.</p> <p>So far I believe the faster and most compatible method (among different Python versions) is the plain simple <code>+</code> sign:</p> <pre><code>text = "whatever" + " you " + SAY </code></pre> <p>But I keep hearing and reading it's not secure and / or advisable.</p> <p>I'm not even sure how many methods are there to manipulate strings! I could count only about 4: There's <a href="http://en.wikipedia.org/wiki/Variable_interpolation#Interpolation" rel="nofollow noreferrer">interpolation</a> and all its sub-options such as <code>%</code> and <code>format</code> and then there's the simple ones, <code>join</code> and <code>+</code>.</p> <p>Finally, the <a href="http://docs.python.org/release/3.0.1/whatsnew/3.0.html#pep-3101-a-new-approach-to-string-formatting" rel="nofollow noreferrer">new approach to string formatting</a>, which is with <code>format</code>, is certainly not good for backwards compatibility at same time making <code>%</code> not good for forward compatibility. But should it be used for every string manipulation, including every concatenation, whenever we restrict ourselves to 3.x only?</p> <p>Well, maybe this is more of a wiki than a question, but I do wish to have an answer on <strong>which is the proper usage of each string manipulation method</strong>. And which one could be generally used with each focus in mind (best all around for compatibility, for speed and for security).</p> <p>Thanks.</p> <p>edit: I'm not sure I should accept an answer if I don't feel it really answers the question... But my point is that all them 3 together do a proper job.</p> <p>Daniel's most voted answer is actually the one I'd prefer for accepting, if not for the "note". I highly disagree with <em>"concatenation is strictly using the + operator to concatenate strings"</em> because, for one, <code>join</code> does string concatenation as well, and we can build any arbitrary library for that.</p> <p><strong>All current 3 answers are valuable</strong> and I'd rather having some answer mixing them all. While nobody volunteer to do that, I guess by choosing the one less voted (but fairly broader than THC4k's, which is more like a large and very welcomed comment) I can draw attention to the others as well.</p>116631377154 0 <p>Expand the size of your <code>q1</code> buffer. <code>scanf("%s", q1)</code> doesn't have enough room to store the input. Remember that C uses a null character <code>'\0'</code> to terminate strings. If you don't account for that, the buffer could overrun into other memory causing <a href="https://en.wikipedia.org/wiki/Undefined_behavior" rel="nofollow">undefined behavior</a>. In this instance, it's probably overwriting memory allocated to <code>name</code>, so <code>name</code> ends up pointing to "\0ick". This causes <code>printf(%s)</code>, which looks for <code>'\0'</code> to know when to stop printing, to think that the string is shorter than it really is.</p> <p>The code works perfectly if you expand the buffer:</p> <pre><code>#include <stdlib.h> #include <stdio.h> #include <string.h> int main(void) { char name[50]; char q1[50]; printf( " What is your name?\n"); scanf("%49s", name); printf( " Hi %s, Do you want to have some fun?

Nick Hi Nick, Do you want to have some fun? [Y/N] y Awesome, let's play!

In simple terms, the <code>HashSet<T></code> class can be thought of as a <code>Dictionary<TKey, TValue></code> collection without values.</p> </blockquote> <p>So it is a collection, containing actual values. The sentence you quoted there is false.</p> <p>That being said, you <em>could</em> create an <code>ISet<T></code> implementation that works that way, e.g. representing numbers in a set as ranges.

Are the folders still empty, or is there content in them now?</p> <p>Git doesn't track folders, it only tracks files. So you can't add an empty folder into the Git repo, if that's what you're trying to do. If you really want the directory there, the standard practice is to add an empty <code>.gitkeep</code> file into it, so that Git has some content to track there.

Drupal is not very strong if all you're doing is building [x], where [x] is an online store, blog, forum, rss aggregation site, etc. We recently retooled our company store in Drupal using the Ubercart plugin suite, though, and were able to exercise a lot of control over the final results -- and more importantly, intgrate it better with the rest of our site's content.</p> <p>That's where the real win is -- if you have lots of existing content and/or community, and you want that integrated smoothly with your store.

Since you are already using HTTP, somehow you are already doing REST like calls and moving these calls to full fledged REST will be easy.</p> <p>Implementing REST calls is easy. You have two approaches: </p> <ul> <li>Low end: using URLConnection objects on the client, servlets on the server and following some REST conventions on using HTTP methods and 'clean' URLs (see <a href="http://en.wikipedia.org/wiki/Clean_URL" rel="nofollow">here</a>). Advantage is that you need no 3rd party library and minimize the footprint. Maintenance and evolutions are harder though.</li> <li>High-end: a framework and specifications like JAX-RS. Using <a href="http://www.restlet.org/" rel="nofollow">Restlet</a> you can be up in running with a REST server in a couple of hours without having to deploy a servlet container.</li> </ul> <p>Don't use SOAP.
