If you are following the instructions to build log4cxx 0.10 in Visual Studio 2005, and you have the Windows Platform SDK v6.0 installed, you may get errors compiling multicast.c in the apr project.
I found the solution, and it’s pretty easy. Open up multicast.c and edit the lines:
136: #if MCAST_JOIN_SOURCE_GROUP
148: #if MCAST_JOIN_SOURCE_GROUP
to [...]

When I was 9, I started playing with GW-BASIC by typing in programs found in the old kid’s 3-2-1 Contact magazine. This soon progressed to QBASIC, where I mostly made cool graphics with lines and circles.

QBASIC is not included in Windows anymore, but you can still get it.

Tracking changes in database tables is an incredibly useful feature–especially for operational data that can change often. Having recently had to implement this feature, I thought I’d share some of the techniques I learned.

Sample Database
First, let’s conceptualize a very simple database consisting of user information (name, date of birth), and e-mails. A user can have [...]

I’ve setup a new domain for a front page for my software hobbies and what will eventually be my “store front”:
Geek Softworks
It uses WordPress, but it’s not a blog–it’s for the software I write. So far, only a few products are up, including DiskSlicer (a new version!), Windows Media Top 10 Plugin, and Word Count [...]

This kind of thing has happened to be a few times now, so I thought I’d share the fun.
In one of our pieces of software we have a process that looks like this:

void MyThread()
{
while (true)
{
DoFunctionA();

Working on an MFC app that has just been converted to Unicode (finally!), I noticed that one button (which is created dynamically) is too small to fit the text in Korean (and Russian and a few other languages).
The code was calling something like:

CSize sz = m_btAdjustColors.GetDC()->GetTextExtent(sCaption);

It seems correct, but these script languages are throwing it [...]

The importance of measuring performance changes is a topic that has been covered by others smarter and more experienced than me, but I have a recent simple tale.
I’ve simplified the code quite a bit in order to demonstrate the issue. Suppose I have a wrapper around an image (it has many more attributes):

One of the key requirements for being able to reliably update software is the confidence that the changes you are making are safe. The amount of confidence required increases with the complexity of the system.
In my day job I work on a real-time messaging system that can have very, very little downtime. As the service [...]

In C#, If you need to unit test a class that fires an event in certain circumstances (perhaps even asynchronously), you need to handle a little more than just running some code and doing the assertion. You have to make sure your unit test waits for the event to be fired. Here’s one naive way [...]

Another one of those lessons learned posts. I know I’m supposed to merge changes across branches often to minimize the pain, but I didn’t do it.
Here’s the scenario: We’ve got 3 development branches: 6.3, 6.4, and 7.0 (the trunk). 6.3 and 6.4 are technically maintenance branches because we didn’t anticipate needing to them, but we [...]
