25,294,454 | 0 | <p>It really depends on what scope you want the iterator to have. Generally speaking, you want to restrict its scope as much as possible while still letting it to its job<sup>1</sup>.</p> <p>If you're only going to use it inside the body of the loop, then it's preferable to define it in the loop header, so its scope is restricted to the loop body.</p> <p>If you're going to use it after the end of the loop, then define it above the loop so it still exists after the end of the loop.</p> <p>Of course, you generally want to avoid the whole question, such as by using a standard algorithm or range-based for loop (usually with <code>auto</code> instead of specifying the type explicitly).</p> <hr> <p><sub> 1.

23,709,460 | 0 | When using the *sync functions in Node.js, what (if any) background operations continue to run <p>When using the Node.js *Sync functions (I understand you shouldn't, and the reasons why), what (if any) background processes continue to run?</p> <p>For example, if I'm using http.createServer, and from one of the requests I call fs.writeFileSync(), will the server continue to serve new clients whilst that write is in progress (not just accept the connection, but process the entire request)? I.e. would writeFileSync() block the entire process, or just the current call chain?</p> |

7,393,812 | 0 | Ruby send method with rails associations <p>I have been messing about with making a sortable table module thing. I know some might exist but want to get experience doing this myself. I had the idea of have it like so:</p> <pre><code>SortedTable.new(ModelName, Hash_Of_Columns_And_Fields, ID) </code></pre> <p>example</p> <pre><code>SortedTable.new(Post, {"Title" => "title", "Body" => "body", "Last Comment" => "comment.last.title"}, params[:id]) </code></pre> <p>I am planning to do something like:</p> <pre><code>def initialize(model, fields, id) data = {} model = model.capitalize.constantize model.find(id) fields.each do |column, field| data[column] = model.send(field) end end </code></pre> <p>This works fine for title and body but when it comes to getting the <code>Last Comment</code> with <code>comment.last.title</code> it errors out. I have tried doing <code>Post.send("comments.last.title")</code> but says <code>NoMethodError: undefined method 'comments.last.title' for #<Post:0x0000010331d220></code></p> <p>I know I can do <code>Post.send("comments").send("last").send("title")</code> and that works but I can not think of how to do that dynamically by taking the fields and spliting the on . then chaining the sends. Can anyone give me advice on how to do this? If I am doing this completely wrong also then please say or point me in the direction of code that does something similar. I am not a expert ruby developer but I am trying.</p> <p>P.S The above code might not work as I am not at a computer with ruby/rails to test, but hopefully you get the concept.</p> <p>Cheers</p> |

23,349,358 | 0 | <p>If your target systems are managed by reasonable people, the software will be managed by the packaging system. On Redhat, Fedora, CentOS or SUSE systems that will be RPM. On any system derived from Debian it will be APT.</p> <p>So your script can check for one of those two packaging systems. Although be warned that you can install RPM on a Debian system so the mere presence of RPM doesn't tell you the system type. Packages can also be named differently. For example, SUSE will name things a bit differently from Redhat.</p> <p>So, use <code>uname</code> and/or <code>/etc/issue</code> to determine system type. Then you can look for a particular package version with <code>rpm -q apache</code> or <code>dpkg-query -s postgresql</code>.</p> <p>If the systems are managed by lunatics, the software will be hand-built and installed in /opt or /usr/local or /home/nginx and versions will be unknown.

I have tried fitting it in normal distribution. </p> <p>But I am more curious to know which distribution does the data carry within itself ? </p> <p>I have no code to show my progress as I have failed to find any functions in python that will allow me to test the distribution of the dataset. I do not want to slice the data and force it to fit in may be normal or skew distribution. </p> <p>Is any way to determine the distribution of the dataset ?

Ask these questions in this order, and stop when the first rule applies.</p> <ol> <li><p>Is the function called with new (<strong>new binding</strong>)? If so, this is the newly constructed object.</p> <ul> <li>var bar = new foo()</li> </ul></li> <li><p>Is the function called with call or apply (<strong>explicit binding</strong>), even hidden inside a bind hard binding? If so, this is the explicitly specified object.</p> <ul> <li>var bar = foo.call( obj2 )</li> </ul></li> <li><p>Is the function called with a context (<strong>implicit binding</strong>), otherwise known as an owning or containing object? If so, this is that context object.</p> <ul> <li>var bar = obj1.foo()</li> </ul></li> <li><p>Otherwise, default the this (<strong>default binding</strong>). If in strict mode, pick undefined, otherwise pick the global object.</p> <ul> <li>var bar = foo()</li> </ul></li> </ol> </blockquote> <p>Note: In ES6, <code>this</code> is the <strong>lexical <code>this</code></strong> for fat arrow functions <code>=></code> and with object short hand notation (e.g., <code>sampleMethod() {}</code>), meaning that <code>this</code> takes on the outer context as reference. </p> |

I am getting an error message from Xcode "Snapshotting a view that has not been rendered results in an empty snapshot. Ensure your view has been rendered at least once before snapshotting or snapshot after screen updates." It sounds to me like this could be the problem, and I have googled it, but havn't gotten any wiser. A lot of people write it's an Apple bug and I havn't found anybody offering a solution. </p> <p>So do anybody know if it is the Xcode error that is my problem, and in that case have a solution for that or have I written something wrong in my code:</p> <pre><code>import UIKit class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate, CustomOverlayDelegate { var picker = UIImagePickerController() @IBAction func shootPhoto(sender: AnyObject) { if UIImagePickerController.availableCaptureModesForCameraDevice(.Rear) != nil { picker = UIImagePickerController() //make a clean controller picker.allowsEditing = false picker.sourceType = UIImagePickerControllerSourceType.Camera picker.cameraCaptureMode = .Photo picker.showsCameraControls = false //customView stuff let customViewController = CustomOverlayViewController( nibName:"CustomOverlayViewController", bundle: nil ) let customView:CustomOverlayView = customViewController.view as!

23,255,242 | 0 | <p>This is because the function works in a separate workspace than the rest of the script.

18,271,321 | 0 | <p>You should implement a sliding window approach. In each window, you should apply the SVM to get candidates. Then, once you've done it for the whole image, you should merge the candidates (if you detected an object, then it is very likely that you'll detect it again in shift of a few pixels - that's the meaning of candidates).</p> <p>Take a look at the V&J code at openCV or the latentSVM code (detection by parts) to see how it's done there.</p> <p>By the way, I would use the LatentSVM code (detection by parts) to detect vehicles.

3,778,668 | 0 | <p>It would not be doing you any favors to help you refactor this code. LINQ to Entities queries are eventually translated into SQL, and this SQL is going to be a mess no matter how good the code looks. You need to reconsider your querying strategy based on the tools your database gives you. Ideally, you should be able to write a query which uses an index.</p> <p>There are two strategies to consider: Collations and schema changes.</p> <p>You haven't mentioned which database you are using, but most databases offer collations which are accent-insensitive for WHERE searches. You should consider changing the collation on the column to one of these.</p> <p>Regarding the dollar signs and the like, you probably won't find a collation which would just ignore these unless you write it yourself. So a different option would be to have a separate column in the database, updated by a trigger, which contains the first and last name with these characters removed. Run your search against that, instead, and an index on these columns can be used.</p> |

24,933,644 | 0 | <p>I had to read your post multiple times to try to get what you were looking for. If I'm reading you correctly, what you want is the first <code><a></code> tag to act as a <code>display:block</code> so that when you hover over it the entire width is clickable, but you want the second <code><a></code> tag to float to the right on the same line.</p> <p>I believe that <a href="http://jsfiddle.net/Arwxh/" rel="nofollow"><strong>this demo</strong></a> will accomplish what you wish. I changed the order of the anchor links to make it as easy as possible. Also added background colors so you could see what's going on.</p> <pre><code><li class="file"><a href="" class="delete">Delete</a><a href="">Long Link Name</a> </code></pre> <p>The CSS required would be:</p> <pre><code>ul.tree li { list-style: none; padding: 0px; padding-left: 20px; margin: 0px; white-space: nowrap; } ul.tree a { color: #111; text-decoration: none; display: block; padding: 0px 2px; background-color: gold; //so you can see what's happening } ul.tree .delete { background-color: lightgreen; //so you can see what's happening margin: 0 0 0 5px; display: inline; float: right; } ul.tree a:hover { background-color: lightblue; //so you can see what's happening } .tree li.directory { background: url(/images/directory.png) left top no-repeat; } .tree li.file { background: url(/images/file.png) left top no-repeat; } </code></pre> <p>If changing the order of the anchors is out of the question, I could muck around with some more elaborate CSS, but as the complexity of the CSS increases, so do your chances of it breaking in one browser or the other. </p> <hr> <p><strong>EDIT:</strong> Based on your reply, I've created some CSS to add an ellipsis (…) when the link text is too long. It requires setting a width on the main <code><ul></code>, but from your initial question it sounds like you're doing that anyway. You can see the <a href="http://jsfiddle.net/Arwxh/5/" rel="nofollow">updated JSFiddle here</a>, and here's the updated CSS:</p> <pre><code>ul { width: 333px; } ul ul { width: inherit; } a { overflow: hidden; text-overflow: ellipsis; } ul.tree li { list-style: none; padding: 0px; padding-left: 20px; margin: 0px; white-space: nowrap; } ul.tree a { color: #111; text-decoration: none; display: block; padding: 0px 2px; background-color: gold; //so you can see what's happening } ul.tree .delete { background-color: lightgreen; //so you can see what's happening margin: 0 0 0 5px; display: inline; float: right; } ul.tree a:hover { background-color: lightblue; //so you can see what's happening } .tree li.directory { background: url(/images/directory.png) left top no-repeat; } .tree li.file { background: url(/images/file.png) left top no-repeat; } </code></pre> <p><a href="http://jsfiddle.net/Arwxh/" rel="nofollow"><strong>Original Fiddle</strong></a> | <a href="http://jsfiddle.net/Arwxh/5/" rel="nofollow"><strong>Fiddle with long links</strong></a></p> |

The next step for me is to create a native ios app using Phonegap. </p> <p>My guess is all I have to do is in the html page which I put in Phonegap, I will hook into page load event and dynamically load the contents of my MVC view from a remote server.</p> <p>But I am looking for some examples if anyone else has done something similar.</p> <p>-Thanks in advance Nick</p> <p><strong>UPDATE:</strong> I was able to accomplish this by writing the following index.html page.

29,423,834 | 0 | How to apply JSON data to an EmberJS Model Attribute <p>I'm very new to JS and I'm retrying EmberJS due to the impending 2.0 but especially because of EMBER CLI which I really like the structure.</p> <p>Anyways, I'm building a basic app and what I'm currently looking to do is make a JSON call to reddit to grab the subscriber number and apply that number to a models subscriber number attribute. I'll also be cycling through an array of models too.</p> <p>So for my instance, I've got models of lets say sports teams. Each team as a subreddit and when someone clicks the league they want, I'll be displaying all of the teams in that league.</p> <p>I've got the the JSON working from a pure JS aspect, and I've got the Ember app working w/o any JSON. So I'm just trying to figure out how to connect the two while also realizing I will probably need to do some tear down to properly connect the two.</p> <p>So my question is, how do I go about selecting a single piece of data from Reddit API to a single model attribute?</p> <p>Here is the JS I'm using currently to pull the subscriber number.</p> <pre><code>$.each( teamList, function( key, val ) { $.getJSON( "http://api.reddit.com/r/"+val+"/about", function foo(data) { $("#team").append(val + " : "); $("#team").append(data.data.subscribers + '<br>'); } ); }); </code></pre> <p>My current ember model setup is normal, but I am using fixtures since all data is static other than this model attribute.</p> |

28,026,010 | 0 | How to run the script both 'on load' and 'on resize' (on a particular window width!) in jQuery? <p>In my current website project I've integrated <a href="https://github.com/alvarotrigo/fullPage.js" rel="nofollow">Alvaro Trigo's FullPage plugin</a> but since it had a very uncommon behaviour on mobile devices (also due to my project's design requirements), I've decided to switch it off when the viewport width is below 768px. For this purpose I just add a simple if-statement to the script:</p> <pre><code>$(document).ready(function(){ if ($(window).width() > 768 ) { $('#fullpage').fullpage({ // code... code... code... }); } }); </code></pre> <p>The problem is that it only takes effect after refreshing the page; so when I go below 768px and reload the page the plugin is switched off, but when I then resize the browser above the mentioned breakpoint, it's still off (and vice versa). I think I should add some lines of code dealing with resize, but unfortunately my current knowledge of JS/jQ doesn't let me do that. Thanks in advance for your time.</p> |
