33,929,120 | 1 | Sharing heavy calculations result when using DRF serializer with many=True <p>There is a simple DRF serializer which:</p> <pre><code>class MySeriliazer(serializers.Serializer): some_field = serializers.SerializerMethodField(read_only=True) def get_some_field(self, obj): some_list = utils.do_some_heavy_calculations() return some_list[obj.some_field] </code></pre> <p>As you see I have a <code>some_field</code> field which value is calculated via some function.</p> <p>When I get a single object it's a big of a problem, but when I use this serializer with <code>many=True</code> thus receiving multiple objects <code>do_some_heave_calculations</code> get called for each, which is very expensive.</p> <p>Moreover sometimes there are few fields which use the same heavy function. like:</p> <pre><code>class MySeriliazer(serializers.Serializer): some_field1 = serializers.SerializerMethodField(read_only=True) some_field2 = serializers.SerializerMethodField(read_only=True) def get_some_field1(self, obj): some_list = utils.do_some_heavy_calculations() return some_list[obj.some_field1] def get_some_field2(self, obj): some_list = utils.do_some_heavy_calculations() return some_list[obj.some_field2] </code></pre> <p>Function is called twice for each object. Not good. What are the options to solve this? Sure enough I can grab these results from some cache which is updated every second. But I think it's possible to extract these calculations somehow and share them during the serialization process.</p> <p>If needed - I use DRF generic views.</p> |

6,580,639 | 0 | Newbie and PHP Frameworks <p>I am a newbie in PHP Frameworks and would like to share/discuss some experience with you guys. Getting straight to the point, what I understand till now (from a newby stand of point is this):</p> <ul> <li>CodeIgniter + Doctrine + Twigg = Symfony:</li> <li><p>Zend + Doctrine + Twigg = Symfony</p> <ol> <li>Symfony 2, uses php5.3 (I realy like namespace stuff remind me .Net) but it lucks of tutorials right now (only partial jobeet translation to ver2)</li> <li>I enjoy CI community and noumerous tutorials, plus using Doctrine + Twigg I could achive the same with Symfony. </li> <li>Zend is more enterprise with lots of tutorials, but more difficult to grasp than CI.</li> </ol></li> </ul> <p>So the question is should I start with CI + Doctrine or learn directly Symfony2? Am I correct with the above assumptions?</p> |

13,635,072 | 0 | <p>Compilation is slowed down a bit because of the way that CodeContracts work. There is an IL re-writer that injects code into your methods based on the contracts that you specify. This happens after the C# compiler has come along and generated the IL for your assembly. </p> <p>The runtime performance difference is quite small and will not affect your code in a noticeable way. Unless you are developing some real-time stock trading system, I seriously wouldn't even worry about it.</p> <p>As far as disabling Code Contracts in Production, I would far rather have the added protection of Code Contracts that some possibly obscure error. An error in the code contract will tell you exactly where and why the Contract was violated as opposed to having to dig down in some deep call-stack just because some bad data was passed in 5 levels up the call-stack tree.</p> <p>If you are using or are planning to use <code>Contract.Requires<TException></code> and do not enable 'Runtime Contract Checking', you'll get a runtime failure about the IL rewriter needing to be bound to the usage of Code Contracts. You will then be required to enable Runtime Contract Checking to get this to work.</p> <p>IMHO, the use of <code>Contract.Requires<TException>()</code> is far more useful than <code>Contract.Requires()</code> since you have control over the type of exception thrown.</p> <p>EDIT: One thing I forgot to add is that the IL Rewriter is completely independent of the C# compiler and there are no dependencies between the two.</p> |

10,951,319 | 0 | Canvas versus DOM - What is the most efficient image display method in HTML5? <p>StackOverflow users</p> <p>While making a html5 application/website, for such cases as an image gallery, where a large number of images are displayed sequentially or at the same time in the browser, is the use of the canvas element justified?</p> <p>As long as we are only talking about presenting an image, is there any point in using a canvas and drawing the image on it instead of using the DOM element < img > tag? There will also be some image manipulation, like CSS3 transformations/moving/scaling/zooming and gesture recognition (drag, touch/tap, maybe pinch, etc.) which, as far as I know, are applicable to both the canvas and the img tags.</p> <p>It would also be important to keep things as much "html5"-ish as possible and also taking performance into account. For example, it would matter if in the future the canvas element will be more and more used and optimized by the browsers and it would also matter if for the time being the < img > is much faster.</p> <p>Since we are considering developing an universal html5 application, working on desktops and also on mobile devices, performance and speed are a very important factor. However, the tests comparing canvas and < img > were targeting mostly javascript browser games. In this case, the animation is not that important as the memory consumption and overall performance.</p> <p>Are there any resources/studies regarding this particular aspect?</p> |
7,067,802 | 0 | <p>(EDIT: CKoenig has a nice answer.)</p> <p>Hm, I didn't immediately see a way to do this either.</p> <p>Here's a non-type-safe solution that might provide some crazy inspiration for others. </p> <pre><code>open System.Collections.Generic module Dict = type Dictionary<'K, 'V> with member this.Difference<'K2, 'T when 'K2 : equality>(that:Dictionary<'K2, 'T>) = let dict = Dictionary<'K2,'V>() for KeyValue(k, v) in this do if not (that.ContainsKey(k |> box |> unbox)) then dict.Add(k |> box |> unbox, v) dict open Dict let d1 = Dictionary() d1.Add(1, "foo") d1.Add(2, "bar") let d2 = Dictionary() d2.Add(1, "cheese") let show (d:Dictionary<_,_>) = for (KeyValue(k,v)) in d do printfn "%A: %A" k v d1.Difference(d2) |> show let d3 = Dictionary() d3.Add(1, 42) d1.Difference(d3) |> show let d4 = Dictionary() d4.Add("uh-oh", 42) d1.Difference(d4) |> show // blows up at runtime </code></pre> <p>Overall it seems like there may be no way to unify the types <code>K</code> and <code>K2</code> without also forcing them to have the same equality constraint though...</p> <p>(EDIT: seems like calling into .NET which is equality-constraint-agnostic is a good way to create a dictionary in the absence of the extra constraint.)</p> |

10,254,421 | 0 | <p>Most likely Dependency. Associations are normally used to capture some relationship that has meaningful semantics in a domain. So, for example, Secretary 'works for' Manager. Your example is different: you're not capturing meaningful relationships among instances. Therefore Dependency is probably most appropriate.</p> <p>More importantly though: what are you trying to illustrate? Remember to use UML like any other tool - make it work for you. So, for example, it's fine to show a binary association if (a) it helps you and/or (b) it helps you communicate with other team members. The fact that it doesn't comply with the intended UML usage doesn't matter - as long as you find it useful.</p> <p>hth.</p> |

104,890 | 0 | Dealing with the rate of change in software development <p>I am primarily a .NET developer, and in that sphere alone there are at any given time probably close to a dozen fascinating emerging technologies, some of them real game-changers, that I would love to delve into. </p> <p>Sadly, this appears to be beyond the limits of human capacity. </p> <p>I read an article by Rocky Lhotka (.NET legend, inventor of CSLA, etc) where he mentioned, almost in passing, that last year he felt very terribly overwheled by the rate of change. He made it sound like maybe it wasn't possible to stay on the bleeding edge anymore, that maybe he wasn't going to try so hard because it was futile. </p> <p>It was a surprise to me that true geniuses like Lhotka (who are probably expected to devote a great deal of their time to playing with the latest technology and should be able to pick things up quickly) also feel the burn!</p> <p>So, how do you guys deal with this? Do you just chalk it up to the fact that development is vast, and it's more important to be able to find things quickly than to learn it all? Or do you have a continuing education strategy that actually allows you to stay close to the cutting edge?</p> |

933,104 | 0 | Web service calls and proxy authentication in the real world <p>We are developing an app that consists of a web server that hosts a web service (amongst other things) and a client that will be communicating with that web service. Both the client app and the server are expected to be used within a corporate firewall. This application will be packaged up and deployed to organizations across the world—so it needs to be flexible enough to work in multiple types of environments.</p> <p>My question revolves around web service authentication and what is appropriate for real world scenarios. I know some companies have proxy servers that require a separate authentication. How often is this a requirement across organizations? When does the proxy server force the user to authenticate (can you access internal sites without authenticating.. is the authentication for only external sites)?</p> <p>Reason I ask these questions, is I’m not sure what kind of capability we should build into our client application for authentication to the web service. By default, we are taking the current user credentials and passing that up to the server. Do you think this is sufficient? In a case where a company will require some form of alternate authentication for internal access, this will not work. My question revolves around this last case—how often does it happen? Why would a company force alternate credentials for internal access?</p> <p>Thanks!</p> |

14,016,373 | 0 | <p>Although @Sam's suggestions will work fine in most scenarios, I actually prefer using the supplied <code>AdapterView</code> in <code>onItemClick(...)</code> for this:</p> <pre><code>public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Person person = (Person) parent.getItemAtPosition(position); // ... } </code></pre> <p>I consider this to be a slightly more fool-proof approach, as the <code>AdapterView</code> will take into account any header views that may potentially be added using <a href="http://developer.android.com/reference/android/widget/ListView.html#addHeaderView%28android.view.View,%20java.lang.Object,%20boolean%29"><code>ListView.addHeaderView(...)</code></a>. </p> <p>For example, if your <code>ListView</code> contains one header, tapping on the first item supplied by the adapter will result in the <code>position</code> variable having a value of <code>1</code> (rather than <code>0</code>, which is the default case for no headers), since the header occupies position <code>0</code>. Hence, it's very easy to mistakenly retrieve the wrong data for a position and introduce an <code>ArrayIndexOutOfBoundsException</code> for the last list item. By retrieving the item from the <code>AdapterView</code>, the position is automatically correctly offset. You can of course manually correct it too, but why not use the tools provided? :)</p> <p>Just FYI and FWIW.</p> |

6,553,763 | 0 | <p>The problem is that @flits is nil, presumably because your all_flits method is returning nil.</p> <p>However, I'd recommend not putting that logic in the view, breaking up a tag like that. You have several options to make it cleaner:</p> <hr> <p>Option 1: Use the CSS pseudo-class <code>first-child</code> like so:</p> <pre><code> li:first-child { ... } </code></pre> <p>This has the advantage of not requiring any back-end logic or special markup. The only downside is that it has spotty older browser support, e.g. IE6.</p> <hr> <p>Option 2: Use the Rails tag helpers.</p> <pre><code><%= content_tag :li, :class => @flits.first==flit?"first":"" %> </code></pre> <hr> <p>Option 3: Tuck it away in a helper method</p> <pre><code><%= li_for_flit %> </code></pre> <p>Then in the helper:</p> <pre><code>def li_for_flit #spit out your tag here end </code></pre> |

21,680,567 | 0 | javascript reset on close <p>I am not an expert on javascript, and I am currently trying to breakdown a previous programmer's code.</p> <p>He has a window called ADD ACCOUNT that opens up, and you can either make your selections via dropdown selects or by dragging and dropping another account directly onto the window.</p> <p>What I want to do is when the user changes their mind, and they close the window, it should automatically reset all the filters. The user is not actually hitting the reset button. They are just closing the window.</p> <p>Right now, if they close it and open it back up, the previous selection they made are still there. </p> <p>I've been looking through the code, and I found this:</p> <pre><code> var AddAccountWindow = new Ext.Window({ title: 'Add Account', closable:true, closeAction:'hide', y:5, width: 735, height:editPnlHeight-25, plain:true, layout: 'fit', stateful:false, items: AddAcountForm }); </code></pre> <p>Is there anyway I can add a reset feature that will automatically fire when they close the window with the code I provided above?</p> <p>Or do I have to create another function that will fire on close?</p> |

13,713,341 | 0 | <p>You do not see the message from circle because circle is part of the group and thus, only one of the event "dragstart" can be recognized either on the group or the circle, when you try to move circle the event is recognized for the group as circle is part of the group. You can probably add a check inside the function associated with "dragstart" for group to check if the object selected is "circle" and show your message.</p> |
