Just want to add to what was mentioned previously that this: $.each(container.children(), function(j,w) { $(w).unbind().change(function() { … }); }); can be optimized to: container.children().unbind().change(function() { … }); It’s all about chaining, a great way to simplify your code.

Even though maven projects have single parent, they can import any number of other pom’s like this: <dependencyManagement> <dependencies> <dependency> <groupId>org.example</groupId> <artifactId>my-shared-dependencies</artifactId> <version>0.0.1-SNAPSHOT</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> This has two important differences compared to a parent: Plugins defined in the imported pom won’t be imported Dependencies defined in the imported pom won’t be added … Read more
The article Eric pointed to is awesome because it covers details of organising large Python code bases. If you’ve landed here from Google and are trying to find out how to split one large source file into multiple, more manageable, files I’ll summarise the process briefly. Assume you currently have everything in a file called … Read more
Used properly, this can be a useful technique. Say you have a complex, performance critical subsystem with a fairly small public interface and a lot of non-reusable implementation code. The code runs to several thousand lines, a hundred or so private functions and quite a bit of private data. If you work with non-trivial embedded … Read more
The standard answer is to use packages — see the Writing R Extensions manual as well as different tutorials on the web. It gives you a quasi-automatic way to organize your code by topic strongly encourages you to write a help file, making you think about the interface a lot of sanity checks via R … Read more
For a file module.py, the unit test should normally be called test_module.py, following Pythonic naming conventions. There are several commonly accepted places to put test_module.py: In the same directory as module.py. In ../tests/test_module.py (at the same level as the code directory). In tests/test_module.py (one level under the code directory). I prefer #1 for its simplicity … Read more
There is actually a (subtle) difference between the two. Imagine you have the following code in File1.cs: // File1.cs using System; namespace Outer.Inner { class Foo { static void Bar() { double d = Math.PI; } } } Now imagine that someone adds another file (File2.cs) to the project that looks like this: // File2.cs … Read more
