I have upgraded my hosting database to MySQL 5. Let's see whether it gives me any trouble. So far it seems to be much faster, than the previous version.

Have a look at the new project - Burstsort.

Quoting from Wikipedia:

Burstsort and its variants are cache-efficient algorithms for sorting strings and are faster than quicksort and radix sort for large data sets.

Drupal doesn't have a built-in support for mobile and handheld devices (PDAs). If you want to make your site more accessible to mobile users, your only option now is to have an additional "mobile" theme in your set-up, which would be very simple and lean, and somehow use it automatically when users access your site from small devices.

Some time ago Microsoft released a free sample - an HTTP server, written completely in .NET and able to host ASP.NET applications. It has been extended and improved by some other company, which now makes it available for download.

There is an open source .NET wrapper for (former) SleepyCat Berkeley DB file database system - you can find it on SourceForge.

In C++ you can declare class methods as const. The idea is that a const method does not change the value of instance' member variables (and doesn't call non-const methods on them).

Looking for a way to integrate Subversion with Visual Studio .NET 2005 I came across AnkhSVN - an open source VS.NET plugin which does exactly that.

My current tests show that it's quite good. Maybe I won't remove my TortoiseSVN yet, but now I don't need to switch to Explorer when I want to commit a change.

I was deeply disappointed to discover, that .NET framework 2.0 didn't contain XQuery implementation.
