17,452,084 | 0 | <p>Very good question.</p> <p><strong>Event handlers are executed in order of initialization.</strong></p> <p>I haven't really thought about this before, because my handlers never needed to know which one run first, but by the look of you fiddle I can see that the handlers are called in the same order in which they are initialized.</p> <p>In you fiddle you have a controller <code>controllerA</code> which depends on two services, <code>ServiceA</code> and <code>ServiceB</code>:</p> <pre class="lang-js prettyprint-override"><code>myModule .controller('ControllerA', [ '$scope', '$rootScope', 'ServiceA', 'ServiceB', function($scope, $rootScope, ServiceA, ServiceB) {...} ] ); </code></pre> <p>Both services and the controller define an event listener.</p> <p>Now, all dependencies need to be resolved before being injected, which means that both services will be initialized before being injected into the controller. Thus, handlers defined in the services will be called first, because service factories are initialized before controller.</p> <p>Then, you may also observe that the services are initialized in order they are injected. So <code>ServiceA</code> is initialized before <code>ServiceB</code> because they are injected in that order into the controller. If you changed their order inside the controller signature you'll see that their initilization order is also changed (<code>ServiceB</code> comes before <code>ServiceA</code>).</p> <p>So, after the services are initialized, the controller gets initialized as well, and with it, the event handler defined within.</p> <p>So, the end result is, on $broadcast, the handlers will be executed in this order: <code>ServiceA</code> handler, <code>ServiceB</code> handler, <code>ControllerA</code> handler.</p> |

5,248,219 | 0 | about number of bits required for Fibonacci number <p>I am reading a algorithms book by S.DasGupta. Following is text snippet from the text regarding number of bits required for nth Fibonacci number.</p> <blockquote> <p>It is reasonable to treat addition as a single computer step if small numbers are being added, 32-bit numbers say. But the nth Fibonacci number is about 0.694n bits long, and this can far exceed 32 as n grows. Arithmetic operations on arbitrarily large numbers cannot possibly be performed in a single, constant-time step.</p> </blockquote> <p>My question is for eg, for Fibonacci number F1 = 1, F2 =1, F3=2, and so on. then substituting "n" in above formula i.e., 0.694n for F1 is approximately 1, F2 is approximately 2 bits, but for F3 and so on above formula fails. I think i didn't understand propely what author mean here, can any one please help me in understanding this?</p> <p>Thanks</p> |
31,710,546 | 0 | Responsive divs without using flexbox <p>I'm working on a chat interface at the moment and currently have the viewport height to 100vh, with a header/navbar, a "main content" section, and the footer where the input field is located - (see fiddle <a href="http://jsfiddle.net/2L8q3r5h/15/" rel="nofollow">here</a>)</p> <p>The way I have it currently coded has the "main" section receive content from the AJAX calls made via the input field in the footer.

2,289,003 | 0 | <blockquote> <p>So, the "inheritance" of static members merely looks like namespace pollution</p> </blockquote> <p>That's right, except that one guy's pollution is another guy's added spicy flavouring.</p> <p>I think Martin Fowler, in his work on DSLs, has suggested using inheritance in this way to allow convenient access to static methods, allowing those methods to be used without class name qualification. So the calling code has to be in a class that inherits the class in which the methods are defined. (I think it's a rotten idea.)</p> <p>In my opinion, static members should not be mixed into a class with a non-static purpose, and the issue you raise here is part of the reason why it's important not to mix them.</p> <p>Hiding private static <em>mutable</em> data inside the implementation of an otherwise "instancey" class is particularly horrible. But then there are static methods, which are even worse mixers. Here's a typical use of static methods mixed into a class:</p> <pre><code>public class Thing { // typical per-instance stuff int _member1; protected virtual void Foo() { ... } public void Bar() { ... } // factory method public static Thing Make() { return new Thing(); } } </code></pre> <p>It's the static factory method pattern. It's pointless most of the time, but even worse is that now we have this:</p> <pre><code>public class AnotherThing : Thing { } </code></pre> <p>This now has a static <code>Make</code> method which returns a <code>Thing</code>, not a <code>AnotherThing</code>.</p> <p>This kind of mismatch strongly implies that anything with static methods should be sealed. Static members fail to integrate well with inheritance. It makes no sense to have them heritable. So I keep static things in separate static classes, and I gripe about redundantly having to declare every member static when I've already said that the class is static.</p> <p>But it's just one of those too-late-now things. All real, working languages (and libraries, and products) have a few of them. C# has remarkably few.</p> |

(alertTitle, alertText, alertNumber, and alertAddress) </p> <p>When looking at the code, the problem is where the alertAddress is involved. Also keep alertNumber in mind.

39,372,636 | 0 | Slow Small Webpack 2 Build - Tree Shaking - Sass - Chunking <p>I've put together a very basic webpack 2 build, but it seems to be slow for the project size. The three things I wanted have were:</p> <ol> <li>Chunking (js & scss)</li> <li>SCSS compiling</li> <li>Tree Shaking</li> </ol> <p>Webpack seemed to be a good choice for being able to do these things. I've been using Gulp and Rollup, but the SCSS/Chunking along side of the tree shaking is a nice thing. </p> <p>It takes around 4000 - 5000ms to compile the build, which wouldn't be the end of the world except the project is so small, so I'm worried about that becoming much larger as a project grows.</p> <p>I've tried a couple things to improve the speed.</p> <pre><code>resolve : { root: path.resolve(__dirname,'src') } </code></pre> <p>This did help, reducing the time by a couple hundred ms, so that was great. I tried to take this further by also resolving alias, but that didn't really show any gains as far as I could tell.</p> <p>I set devTool to eval as well. Beyond this I haven't really been able to improve things, but I'm sure it's something in the way I've set things up. It's worth noting that while 'webpack' compiles the build, running the webpack-dev-server doesn't. It's starts up, hangs on the compile and then crashes. This may or may not be a separate issue, but I thought it was worth including. </p> <p>I'm also using ES6 System.import for chunking (just as a note).</p> <p>I put the project up on git, so feel free to pull it down: <a href="https://github.com/loriensleafs/trying-out-webpack2" rel="nofollow">https://github.com/loriensleafs/trying-out-webpack2</a></p> <p>The webpack.config.js is:</p> <pre><code>var path = require('path'), webpack = require('webpack'), CleanPlugin = require('clean-webpack-plugin'), ExtractTextPlugin = require('extract-text-webpack-plugin'), production = process.env.NODE_ENV === 'production'; var plugins = [ new ExtractTextPlugin({ filename: 'bundle.css', allChunks: true}), new webpack.optimize.CommonsChunkPlugin({ name : 'vendor', children : true, minChunks : 2 }) ]; if (production) { plugins = plugins.concat([ new CleanPlugin('builds'), new webpack.optimize.DedupePlugin(), new webpack.optimize.OccurenceOrderPlugin(), new webpack.optimize.MinChunkSizePlugin({ minChunkSize: 51200, // ~50kb }), new webpack.optimize.UglifyJsPlugin({ mangle: true, compress: { warnings: false, // Suppress uglification warnings }, }), new webpack.DefinePlugin({ __SERVER__ : !production, __DEVELOPMENT__ : !production, __DEVTOOLS__ : !production, 'process.env': { BABEL_ENV: JSON.stringify(process.env.NODE_ENV), } }) ]); } module.exports = { // debug : !production, devTool : production ? false : 'eval', entry : './src', output : { path : 'builds', filename : 'bundle.js', chunkFilename : 'chunk.js', publicPath : 'builds/' }, resolve : { root: path.resolve(__dirname,'src') }, plugins : plugins, module : { loaders: [ { test : /\.(png|gif|jpe?g|svg)$/i, loader : 'url', query : { limit: 10000 } }, { test : /\.js$/, include : /src/, exclude : /node_modules/, loader : 'babel' }, { test : /\.scss$/, include : /src/, exclude : /node_modules/, loader : ExtractTextPlugin.extract(['css','sass']) }, { test : /\.html$/, loader : 'html' } ] } }; </code></pre> <p>Thanks for any advice/help folks have on this.

If the map doesn't need to change then one of the above suggestions would probably be better.</p> <p>If redrawing the graphic is the intention, then it would be necessary to discuss how you are generating the graphic in order to diagnose the problem. Because of the red "X" problem you are having, it's possible the graphic is not in the correct format, so it may help to post some of that code for further assistance.</p> |

20,370,985 | 0 | <p>As a starting point, use <code>int</code> which is probably native to the architecture and you'll avoid possible implicit conversions when comparing <code>i</code> with other bits and pieces. So my bet is that both <code>byte</code> and <code>short</code> will wind up being <em>slower</em>.</p> <p>A far cuter optimisation would be to use <code>++i</code> rather than <code>i++</code>, as the former will never be slower than the latter. (Conceptually <code>i++</code> has to return a copy even though it will be optimised out by a good java compiler).</p> |

Thanks!</p> <p>Maths for code:</p> <p><strong>2nd click</strong></p> <pre><code>click count = 2 average= current time / 1 so current = time \ click count - 1 </code></pre> <p><strong>3rd click</strong></p> <pre><code>adveragetime + Current Time \ clickcount - 1 </code></pre> <p><strong>4th click</strong></p> <pre><code>average time * (click count -2) + Current Time \ clickcount -1 </code></pre> |
23,344,254 | 0 | <p>[Adding this here since you want a way to do it purely in XAML. I think that insisting on pure XAML here is not essential and @bit's answer is the right way to go, IMO.]</p> <p>You can use style to have triggers that do the change.</p> <p>Let's say your UC is called <code>MyUC</code> and currently you have an instance of it similar to: <code><local:MyUC/></code> in some other view/UC/window. You can change the instance to look like so:</p> <pre><code><local:MyUC> <local:MyUC.Style> <Style TargetType="{x:Type local:MyUC}"> <Setter Property="DataContext" Value="{Binding SelectedItem, ElementName=MyDataGrid}"/> <Style.Triggers> <DataTrigger Binding="{Binding ElementName=MyCheckbox, Path=IsChecked}" Value="True"> <Setter Property="DataContext" Value="{Binding APerson}"/> </DataTrigger> </Style.Triggers> </Style> </local:MyUC.Style> </local:MyUC> </code></pre> <p>I'm changing here the data context property, but you can change any other dependency property on <code>MyUC</code>.</p> <p>Again, I think this is a less favorite approach to tackle this functionality, but it's pure XAML.</p> |
