Release of PowerPC Instruction Set Reference Card, rev 1

This is a quick post to announce that I have just released the first revision of my PowerPC User-Level Instruction Set Quick Reference Card. I think it will be useful to anyone having to deal with 32-bit PowerPC assembly, from people examining compiler output to low-level embedded programmers. You can download it here. Enjoy !

Release of the extract_lines Python module

Yesterday I wrote-up a page about extract_lines, a Python module I developed recently to automate some text extraction tasks. Many engineers have to analyze tabular or line-oriented human-readable reports and source code. For instance, suppose we want to extract constant coefficients from a C source file (snippet taken from Bessel functions of the first kind […]
