Is there hard evidence of the ROI of unit testing?
...t is has significant value. I have to convince the other programmers and, more importantly, the bean-counters in management, that all the extra time spent learning the testing framework, writing tests, keeping them updated, etc.. will pay for itself, and then some.

Relation between CommonJS, AMD and RequireJS?
...e different implementations, but both come from the same origins.
AMD is more suited for the browser, because it supports asynchronous loading of module dependencies.
RequireJS is an implementation of AMD, while at the same time trying to keep the spirit of CommonJS (mainly in the module identifie...
Are Stored Procedures more efficient, in general, than inline statements on modern RDBMS's? [duplica
...ch this isn't the case, so you'll need to test on your target DBMS.
Also, more and more DBMS allow you to provide optimizer path plans (abstract query plans) to significantly reduce optimization time (for both ad hoc and stored procedure SQL!!).
WARNING Cached query plans are not a performance ...

...confuses me. There are WEBrick, Mongrel, Passenger, Apache, Nginx and many more I am sure, and I don't really understand the different roles they play.

Defeating a Poker Bot
...ost of the behavioural simulations you can run are fairly obvious, but the more inconsistant and unpredictable your bot is, the less likely it is to be discovered.

Heap vs Binary Search Tree (BST)
...sed trees, BST only pointer-based trees. So for the heap we can choose the more space efficient array implementation, if we can afford occasional resize latencies.
binary heap creation is O(n) worst case, O(n log(n)) for BST.
Advantage of BST over binary heap
search for arbitrary elements is O(l...
Fatal Error: Allowed Memory Size of 134217728 Bytes Exhausted (CodeIgniter + XML-RPC)
... right 95% of the time. However, there are times when you actually do need more memory. For example, let's say your app is loading a massive amount of data into memory for processing (say a Bill of Material with 15k components). It is not always the case that the code is buggy, sometimes you just ne...
Declaring Multiple Variables in JavaScript
... the second way allows compressors (like the YUI Compressor) to give you a more minified version. If size is a consideration, then I would suggest following as many of JSLint's suggestions as possible.

If my interface must return Task what is the best way to have a no-operation implementation?
...sey's answer about using Task.FromResult, you can improve performance even more if you cache the already completed task since all instances of completed tasks are the same:
public static class TaskExtensions
{
public static readonly Task CompletedTask = Task.FromResult(false);
}
With TaskExte...
