Beamforming in PulseAudio
In case you missed it – we got PulseAudio 9.0 out the door , with the echo cancellation improvements that I wrote about . Now is probably a good time for me to make good on my promise to expand upon the subject of beamforming.

All Software is Legacy
In what may be judged in years to come as a moment of madness, I have volunteered to be the primary maintainer of the Perl CGI module (CGI.pm). For the non-technical readers of this post: CGI.pm is a few thousand lines of code that in the mid to late nineties, and even some years later, was helping many websites…

When code is suspiciously fast: adventures in dead code elimination
Part of a recent assignment for one of my classes involved calculating the Fibonacci sequence both recursively and iteratively and measuring the speed of each method. (BONUS: For a fun diversion, here is a paper I wrote about using the Golden Ratio, which is closely related to the Fibonacci sequence, as a base for a…

Multithreading in modern C++

Mainframes as a lifestyle choice
I started working at IBM last year on mainframe compilers with the goal of making mainframes feel a little more modern. Hence, a lot of my time is spent in z/OS . The interface I use to z/OS is Unix System Services (USS, a.k.a. the command line), but if I were up for bucking the whole moderm thing, I could break out…
