8,447,944 | 0 | How can you universally override the get and post methods in RSpec? <p>I'd like to override the <code>get</code> and <code>post</code> methods in RSpec. </p> <p>I want to do this in order to deal with subdomains in my tests. As far as I can tell, the only way to deal with subdomains is to alter the <code>@request</code> object before each call. I could do this before each and every test but that's going to lead to some really messy code.</p> <p>In an effort to keep things DRY I've tried using a <code>config.before(:each)</code> method in <code>spec_helper.rb</code> however this doesn't seem to be run in the same scope as the test and doesn't have access to <code>@request</code>.</p> <p>My next bsest approach is therefore to overrride <code>get</code> and <code>post</code> which are in the correct scope.</p> <pre><code>def get *args @request.host = @required_domain if @required_domain super *args end </code></pre> <p>I can include this code in the top of each spec file but I'd rather set it universally. If I set it in <code>spec_helper.rb</code> though it does not get called. </p> <p>Where can I set this to override the default <code>get</code> method?</p> |

18,923,384 | 0 | <p>The cause of the problem is twofold:</p> <ol> <li>In your module you have a behaviour declaration <code>-behaviour(cowboy_http_handler).</code>. This is perfectly correct.</li> <li>When you compile the file the compiler can't find the <code>cowboy_http_handler</code> module in its search path</li> </ol> <p>This causes the error as the behaviour declaration tells the compiler to go out and find that module and find out which callback functions the behaviour expects. Normally if the compiler can't find the behaviour module, or if it can find and there are some callbacks missing then it issues a warning about this and just continues. However your Makefile sets a compiler option which treats all warnings as errors so the compilation fails.</p> <p>There are (at least) three solutions to this:</p> <ol> <li>Remove the compiler option and accept you get a warning.</li> <li>Make sure the compiler can find the behaviour module and do the checking. A simple way of doing is to add a <code>-pa Dir</code> option for the cowboy beam file directory so it can find the file.</li> <li>Set up Erlang so that it automatically finds the cowboy directory, for example with <code>$ERL_LIBS</code>.</li> </ol> <p>Note that even if the compiler finds the right module you still have to make sure that when you run the system Erlang can find the directory. There is no automatic equivalence between the compile-time and run-time environments.</p> |

1,225,465 | 0 | Callbacks in Linq-to-SQL/ASP.NET MVC <p>After using .NET for several years, I've spent the last few months in the far off land of Ruby on Rails. While I can clearly see where much of Microsoft's MVC framework got it's influence, one of the things that I find myself suddenly missing when development in .NET are the Rails Model callbacks.</p> <p>Specifically, you can add a callback to <code>before_save, after_save, before_create, after_create</code>, etc. and then specify a function to be called at those points in execution (which seems very similar to aspect oriented programming).</p> <p>My question is, out of the box, does .NET 3.5/ASP.NET MVC offer anything similar to the callbacks in Rails? For example, if I have an <code>inserted_datetime</code> and <code>updated_datetime</code> column on one of my database tables, instead of making sure those columns get updated in the controller, I'd like to be able to tell my model that every time the "Group" object gets saved to the database, update the <code>updated_datetime</code> column.</p> <p>Is this possible? Does this question even make sense?</p> |

9,809,351 | 0 | IE8 CSS @font-face fonts only working for :before content on over and sometimes on refresh/hard refresh <p>UPDATE: I've written a blog post about what I've learned about this issue. I still don't fully understand it, but hopefully someone will read this and shed some light on my issue: <a href="http://andymcfee.com/2012/04/04/icon-fonts-pseudo-elements-and-ie8">http://andymcfee.com/2012/04/04/icon-fonts-pseudo-elements-and-ie8</a></p> <p>I have a page where I'm using @font-face to import a custom font for icons. The icons are created with a class:</p> <pre><code>.icon {font-family: 'icon-font';} .icon:before {content: 'A';} </code></pre> <p>And voila, I have whatever icon is used for "A". Pretty standard stuff, works in all browsers, including IE8. </p> <p>However, in IE8, I have a bizarre bug. When the page loads, the font is not working. Instead of icons, I have letters all over the place. Once I hover OVER the page (body), half the letters become icons. The rest become icons when I hover over them. </p> <p>SO the font-face is embedding properly. The font-family and content properties are both working, but something else is causing the icons to load only after hover.</p> <p>So there's some sort of bug with @font-face in IE8 when you try to use the font with :before{content: 'a'} but I have no idea what the bug is.</p> <p>I've searched for hours on here for a similar bug/IE8 issue/anything, but I've had no luck and I'm about to go crazy. ANY suggestions? </p> <p>Let me know if I can provide anymore info that might be helpful. </p> <p>EDIT: Updated the broken link to the blog post.</p> |

39,505,739 | 0 | OpenCV floodfill while maintaining intensity of objects takes too long to run <p>I am using OpenCV 3.1.0 to change the color of certain areas in an image. OpenCV's floodfill is doing an excellent job of selecting the area and changing the color to a solid new value. But the output image pixels lose their intensity and the shadows in the images are lost.</p> <p>What I need is that the color replacement in floodfill takes into consideration the intensity of the pixel and fill a slightly darker or lighter shade of that color accordingly.</p> <p>What I did -</p> <ol> <li>Converted the original image to HLS color space and saved this Mat separately. Original Image link- <a href="https://www.walldevil.com/wallpapers/a40/thumb/desktop-themes-skins-office-wallpapers-walls.jpg" rel="nofollow">https://www.walldevil.com/wallpapers/a40/thumb/desktop-themes-skins-office-wallpapers-walls.jpg</a></li> <li>Used floodfill on image with new color. Convert this to HLS too. </li> <li>Parsed each pixel of the new image and wherever the floodfill had replaced the color, changed the L value by incrementing or decrementing the new L with the difference between the old L and average L of changed pixels. <a href="http://i.stack.imgur.com/gMVWk.png" rel="nofollow">Output after Intensity Readjustment</a></li> </ol> <p>The problem is first I calculated the average L of changed pixels and then parse each pixel again to adjust the L value. All this is taking too long to execute</p> <p>Is there a way I can optimize my approach for faster output.</p> <pre><code>Mat dst = isColor ? image : gray; int area; if( useMask ) { threshold(mask, mask, 1, 128, THRESH_BINARY); area = floodFill(dst, mask, seed, newVal, &ccomp, Scalar(lo, lo, lo), Scalar(up, up, up), flags); imshow( "mask", mask ); } else { area = floodFill(dst, seed, newVal, &ccomp, Scalar(lo, lo, lo), Scalar(up, up, up), flags); } cvtColor(dst,hsvmask,CV_BGR2HLS); for(int i=0;i<image.rows;i++) for(int j=1;j<image.cols*3;j=j+3) { float o_hue=(float)imghsv.at<uchar>(i,j); float n_hue=(float)hsvmask.at<uchar>(i,j); float s_intensity=(float)imghsv.at<uchar>(y,x*3+1); float o_intensity=(float)imghsv.at<uchar>(i,j); float n_intensity=(float)hsvmask.at<uchar>(i,j); float newIntensity=n_intensity + (o_intensity-s_intensity); hsvmask.at<uchar>(i,j)=((o_hue==n_hue)?o_intensity:newIntensity<0?0:newIntensity); } hsvmask.copyTo(imghsv); cvtColor(hsvmask,dst,CV_HLS2BGR); imshow("image", dst); </code></pre> <p>The code in nested for loops is how I restore the intensity by traversing each pixel. But it is very slow in terms of execution.</p> |

13,729,706 | 0 | <p>If you want to copy the item from index 0 in the first list to index 0 in the second, and so on for all of the other indexes you can do this:</p> <pre><code>var pairs = members.Zip(divisions, (a, b) => new { Member = a, Division = b, }); foreach (var pair in pairs) { Copy(pair.Member, pair.Division); } </code></pre> <p>If the indexes don't match you need to do a join:</p> <pre><code>var pairs = members.Join(divisions , member => member.DivisionId , division => division.DivisionId , (a, b) => new { Member = a, Division = b, }); foreach (var pair in pairs) { Copy(pair.Member, pair.Division); } </code></pre> <p>Note that the <code>Zip</code> will be faster, if the items are already in the proper order. Join will be slower than the Zip, but will be faster than manually re-ordering the items to allow a <code>Zip</code>.</p> |

11,628,374 | 0 | <p>The reason to use a double here is the attempt to provide enough accuracy. </p> <p>In detail: The systems interrupt time slices are given by <em>ActualResolution</em> which is returned by <code>NtQueryTimerResolution()</code>. NtQueryTimerResolution is exported by the native Windows NT library NTDLL.DLL. The System time increments are given by <em>TimeIncrement</em> which is returned by <code>GetSystemTimeAdjustment()</code>.</p> <p>These two values are determining the behavior of the system timers. They are integer values and the express 100 ns units. However, this is already insufficient for certain hardware today. On some systems <em>ActualResolution</em> is returned 9766 which would correspond to 0.9766 ms. But in fact these systems are operating at 1024 interrupts per second (tuned by proper setting of the multimedia interface). 1024 interrupts a second will cause the interrupt period to be 0.9765625 ms. This is of too high detail, it reaches into the 100 ps regime and can therefore not be hold in the standard <em>ActualResolution</em> format.</p> <p>Therefore it has been decided to put such time-parameters into double. But: This does <strong>not</strong> mean that all of the posible values are supported/used. The granularity given by <em>TimeIncrement</em> will persist, no matter what.</p> <p>When dealing with timers it is always advisable to look at the granularity of the parameters involved.</p> <p>So back to your question: <code>Can Interval support values like 5.768585 (ms) ?</code></p> <p><strong>No</strong>, the system I've taken as an example above cannot.</p> <p><strong>But it can support 5.859375 (ms)!</strong></p> <p>Other systems with different hardware may support other numbers.</p> <p>So the idea of introducing a double here is not such a stupid idea and actually makes sense. Spending another 4 bytes to get things finally right is a good investment.</p> <p>I've summarized some more details about Windows time matters <a href="http://www.windowstimestamp.com/description" rel="nofollow">here</a>.</p> |

10,798,274 | 0 | Opening a database connection in a constructor, when should I close it? <p>well, I've been thinking of making database requests a little faster by keeping the connection to the database open as long as the object is being used. So I was thinking of opening the connection in the constructor of that class. Now the question is, how can I close the connection after I stopped using? I have to call close() somewhere, don't I? I've been reading about the finalize() method, but people seemed to be skeptical about usage of this method anywhere at all. I'd expect it to have something like a destructor, but Java doesn't have that, so?</p> <p>So could anyone provide me with a solution? Thanks in advance.</p> |

And using Jquery to select all the corresponding child check box when its parent is checked. The working Jquery and the rendered HTML is in here...<a href="http://jsfiddle.net/srk1982/Gak2h/7/" rel="nofollow">JS Fiddle</a></p> <p>Jquery to select the checkbox :</p> <pre><code> $('.tree').on('change', ':checkbox', function () { var checked = this.checked; var $elem = $(this).closest('table'); var depth = $elem.find('div').length; var $childs = $elem.nextAll('table'); $childs.each(function () { var $child = $(this); var d = $child.find('div').length; if (d <= depth) { return false; } $child.find(':checkbox').prop('checked', checked); }); }); </code></pre> <p>But I do not know how to unselect the parent node when one of its child item is checked.

27,017,971 | 0 | Changing an unhandled exception to a handled one in a finally block <p>Consider this program:</p> <pre><code>using System; static class Program { static void Main(string[] args) { try { try { throw new A(); } finally { throw new B(); } } catch (B) { } Console.WriteLine("All done!"); } } class A : Exception { } class B : Exception { } </code></pre> <p>Here, an exception of type <code>A</code> is thrown for which there is no handler. In the <code>finally</code> block, an exception of type <code>B</code> is thrown for which there is a handler. Normally, exceptions thrown in <code>finally</code> blocks win, but it's different for unhandled exceptions.</p> <p>When debugging, the debugger stops execution when <code>A</code> is thrown, and does not allow the <code>finally</code> block to be executed.</p> <p>When not debugging (running it stand-alone from a command prompt), a message is shown (printed, and a crash dialog) about an unhandled exception, but after that, "All done!" does get printed.</p> <p>When adding a top-level exception handler that does nothing more than rethrow the caught exception, all is well: there are no unexpected messages, and "All done!" is printed.</p> <p>I understand how this is happening: the determination of whether an exception has a handler happens before any <code>finally</code> blocks get executed. This is generally desirable, and the current behaviour makes sense. <code>finally</code> blocks should generally not be throwing exceptions anyway.</p> <p>But <a href="http://stackoverflow.com/questions/2911215/what-happens-if-a-finally-block-throws-an-exception">this other Stack Overflow question</a> cites the C# language specification and claims that the <code>finally</code> block is required to override the <code>A</code> exception. Reading the specification, I agree that that is exactly what it requires:</p> <blockquote> <ul> <li>In the current function member, each <code>try</code> statement that encloses the throw point is examined. For each statement <code>S</code>, starting with the innermost try statement and ending with the outermost try statement, the following steps are evaluated: <ul> <li>If the <code>try</code> block of <code>S</code> encloses the throw point and if S has one or more <code>catch</code> clauses, the catch clauses are examined [...]</li> <li>Otherwise, if the <code>try</code> block or a <code>catch</code> block of <code>S</code> encloses the throw point and if <code>S</code> has a <code>finally</code> block, control is transferred to the <code>finally</code> block. If the <code>finally</code> block throws another exception, processing of the current exception is terminated. Otherwise, when control reaches the end point of the <code>finally</code> block, processing of the current exception is continued.</li> </ul></li> <li>If an exception handler was not located in the current function invocation, the function invocation is terminated, and one of the following occurs: <ul> <li>[...]</li> </ul></li> <li>If the exception processing terminates all function member invocations in the current thread, indicating that the thread has no handler for the exception, then the thread is itself terminated. The impact of such termination is implementation-defined.</li> </ul> </blockquote> <p>An exception isn't considered unhandled, according to my reading of the spec, until <em>after</em> all function invocations have been terminated, and function invocations aren't terminated until the <code>finally</code> handlers have executed.</p> <p>Am I missing something here, or is Microsoft's implementation of C# inconsistent with their own specification?</p> |
27,536,672 | 1 | A dict-like class that uses transformed keys <p>I'd like a dict-like class that transparently uses transformed keys on lookup, so that I can write</p> <pre><code>k in d # instead of f(k) in d d[k] # instead of d[f(k)] d.get(k, v) # instead of d.get(f(k), v) </code></pre> <p>etc. (Imagine for example that <code>f</code> does some kind of canonicalization, e.g. <code>f(k)</code> returns <code>k.lower()</code>.)</p> <p>It seems that I can inherit from <code>dict</code> and override individual operations, but not that there is a centralized spot for such transformation that all keys go through. That means I have to override all of <code>__contains__</code>, <code>__getitem__</code>, <code>get</code>, and possibly <code>__missing__</code>, etc. This gets too tedious and error-prone, and not very attractive unless this overhead outweighs that of manually substituting <code>f(k)</code> for every call on a plain <code>dict</code>.</p> |

27,132,432 | 0 | How to debug %post with rpmbuild <p>I'm building an RPM that needs to run a number of scripts to configure it after it's been installed to complete the installation. I have to run the scripts in the %post section because the configuration is dependent upon the type of host. All this is fairly easy and well, but every time I run into a bug with the %post section, I have to rebuild the entire package which takes about 20 minutes. Is there a way to skip recompiling everything and just build a new package with just the changes from %post?</p> |
2,185,287 | 0 | <p>Yes, as long as your controller inherits from Controller (which it must in order to work as an MVC controller), you can use the same syntax without the <%= %>.</p> <pre><code>Dim url = Url.Action("myAction", "myController", New With { ... }) </code></pre> <p>alternatively if you reference the MVCContrib DLL, you will have access to strongly typed helpers, and be able to do something like:</p> <pre><code>Dim url = Url.Action(Of myController)(function(a) a.myAction(ID)) </code></pre> <p>my VB coding days are dated, so forgive me if the syntax is a bit fudged</p> |
