Debugging complex, real-time, multi-CPU programs like HPVM, Tao3D or the software in the DxO ONE can be a real challenge. You need detailed information about what's going on, but at the same time, adding instrumentation, e.g. a big bunch of ad-hoc printf statements, can change the behavior of the program sufficiently to make the problem you are chasing … Continue reading A real-time, lock-free, multi-CPU flight recorder
Saw this on Twitter a few days ago.
Doing a Tao3D version of the Helvetica Clock Chrome Experiment shows a 33 times reduction in code size compared to the original.
Taodyne just released Tao3D "Libre Edition", a GPLv3 version of Tao3D.
The video below is a quick introduction to the Tao language: The source code is accessible on GitHub. You can download Tao Presentations from the Taodyne web site if you want to try it yourself.
Mozilla Firefox, Chromium (the open-source variant of Chrome) and WebKit (the basis for Safari) are all great examples of open-source software. The Qt project has a simple webkit-based web browser in their examples. So that's at least four different open-source web browsers to choose from. But what does it take to actually build them? The TL;DR … Continue reading Building all the major open-source web browsers
I've been really trying to use LLDB for a while now. Not that I really want to, but Apple went out of its way to make sure I had little choice. Not only is LLDB the default on MacOSX now, but GDB is really hard to make work on that platform as well. Can you imagine you … Continue reading LLDB is a piece of crap (update: maybe it’s clang) (update 2: it’s actually ccache)
