TIME_WAIT perfmon counters
I’ve built a small Windows Service which exposes perfmon counters to track sockets in TIME_WAIT state. It can be downloaded from the links later in this post. Back in 2011 I was helping a client look for issues in their systems caused … -

Bitten by 'scoped static initialisation' in C++ - turn on Visual Studio's C4640 warning!
Today I discovered that C++ scoped static initialisation (function level) in Visual Studio is not done in a thread safe manner. It’s the kind of thing that I should have already known but I guess I assumed that since namespace level … -

Practical Testing: 32 - Intrusive containers.
Back in 2004, I wrote a series of articles called “Practical Testing” where I took a piece of complicated multi-threaded code and wrote tests for it. I then rebuild the code from scratch in a test driven development style to … -

Practical Testing: 33 - Intrusive multi-map.
Previously on “Practical Testing”… I’m in the process of replacing STL containers with custom intrusive containers in the timer system that I have been developing in this series of articles. The idea is that the … -

How to build a GCC Cross-Compiler
This article over on Preshing on Programming looks useful. It gives a step by step guide for building GCC cross-compilers, I expect it will save me lots of time at some point in the future. -

Two quite different approaches to multi-threading
I’ve been working on some code for a client recently that needs to run in a multi-threaded environment. Unfortunately it was never really written with that requirement in mind, or, more likely, the people who wrote the code knew that …
