I’d like to introduce Digbuild, an open-source game engine inspired by the excellent game Minecraft (and Infiniminer before it — that’s right, Minecraft is itself a clone). I’ve been working on it on and off in my spare time for a few months now, and today I decided that it’s ready to show to the […]
I’m doing a little bit of work that involves frequently rebuilding the Linux kernel and installing it on a headless ARM board. The particular ARM board I’m working with has some vendor support for flashing kernels, but it’s slow and clunky, and I have to run it inside a Windows XP VM. The ARM board […]
hide-first-letter slop·ti·mize | slop·ti·mized | slop·ti·miz·ing verb To make a program run faster by decreasing the accuracy of its output. Examples of sloptimize We sloptimized the calculations to use 32-bit floats instead of 64-bit doubles, and got a 20% speedup.
It’s been a long time in the making, but I am proud to announce the first beta release of cppsh, the bash-like shell specifically designed for those engineers who find themselves most comfortable at the reins of a C++ compiler. The best features from both bash and the C++ language come together in cppsh to […]

However, in some circumstances it can cause trouble, particularly when it comes to function overloading. Consider the following C++ template class: template <typename T> struct foobar { foobar( const T foo ) : foo_( foo ) {} […]
