Using ThreadPool.QueueUserWorkItem in ASP.NET in a high traffic scenario
...using. These methods are always very clearly labeled; they start with the words Begin and End. As in Stream.BeginRead, Socket.BeginConnect, WebRequest.BeginGetResponse, and so on.
These methods do use the ThreadPool, but they use IOCPs, which do not interfere with ASP.NET requests. They are a sp...
Is recursion a feature in and of itself?
...the result of that instead
Perhaps you can think of slightly less clunky wording for the latter, but I think you'll always find that the first one is going to be a more accurate description, conceptually, of what you are actually trying to do. This isn't to say recursion is always less readable. F...
File name? Path name? Base name? Naming standard for pieces of a path
...
For a long time I've been using the word "pathname" to mean the entire absolute path including the full filename. Your answer, others here, and resources elsewhere have changed my mind about that, and now i'll use the word "fullpath" for this, "path" for the lo...
Node.js / Express.js - How does app.router work?
...are now processed in precisely the order in which they are added.
In other words:
All routing methods will be added in the order in which they appear. You should not do app.use(app.router). This eliminates the most common issue with Express.
In other words, mixing app.use() and app[VERB]() will wor...
How important is the order of columns in indexes?
...eep them only on the leaf pages, for query coverability purposes. In other words, move them to INCLUDE. This becomes more important as the size of Least column increases.

DateTime vs DateTimeOffset
...lues, they are first normalized to zero offset before comparing. In other words, 2012-01-01T00:00:00+00:00 and 2012-01-01T02:00:00+02:00 refer to the same instantaneous moment, and are therefore equivalent.
If you are doing any unit testing and need to be certain of the offset, test both the DateTi...
Using .NET, how can you find the mime type of a file based on the file signature not the extension
...t the mimetype for .docx is "application/vnd.openxmlformats-officedocument.wordprocessingml.document". While this CAN be determined from a binary-only examination, it's probably not the most efficient way to do it, and in most cases you would have to read in more than the first 256 bytes.
