I write software for a living but in my (increasingly depleted) spare time I enjoy taking programs apart and finding out how they work, writing small utilities for various purposes and improving on other people's work by attempting to write smaller and faster code. This is in contrast to bloatware - the gigantic, unreliable offerings so common in commercial and shareware software these days.
Here are several utilities that I thought I might share with the world. Most of them are finished or in a state of almost completeness due to lack of time (or laziness). As with all software there is often room for improvement and additional functionality so be sure to check back here for updates.
All of the utilities here are 32 bit Windows 9x/NT/2000/XP based programs written in straight Win32 API using Microsoft Visual C++ 6.0/7.0 and released as freeware.
To answer a common question I receive, I do not give out the source code to any of my programs except in exceptional circumstances. Many of the programs are in continual (if slow :-) development and I get lots of emails asking how the final applications work. I cannot afford the time to answer questions about the source code too. There are several good websites that provide examples and entire applications that you can learn from - see my links page for a few of these.
Some people may be forgiven for mistakenly thinking that due to the nature of some of my utilities I endorse hacking or malicious use of these tools. I can only stress that I take no responsibility for any damage or trouble you may get into by using this software. If you are stupid or careless enough to attempt to use any of these programs against an unsuspecting target over the Internet then I should warn you that you will be easily tracked down and quite probably reported to your ISP resulting in a warning or immediate cancellation of your account. The utilities provided here were all written for a specific legitimate purpose and the good intention behind them is endorsed by the fact that many of these programs are highly popular downloads on some of the most respected computer security web sites.
