How to get your SUSE Box to do octave sounds on shutdown

Howtos

One of the things i like most about (gnu/?) linux, other than everything, is how you can get it to do things you never knew you wanted… and that’s what i’m all about, i like to dig down the stuff that creates the WOW-effect, even if it has little or no purpose at all. Being able to convert 8 friends so far, makes me certain that these things really do work on a psychological level.

Programming: C++, Python, LLVM and More

  • Theory: average bus factor = 1

    Two articles recently made me realize that all my free software projects basically have a bus factor of one. I am the sole maintainer of every piece of software I have ever written that I still maintain. There are projects that I have been the maintainer of which have other maintainers now (most notably AlternC, Aegir and Linkchecker), but I am not the original author of any of those projects. Now that I have a full time job, I feel the pain. Projects like Gameclock, Monkeysign, Stressant, and (to a lesser extent) Wallabako all need urgent work: the first three need to be ported to Python 3, the first two to GTK 3, and the latter will probably die because I am getting a new e-reader. (For the record, more recent projects like undertime and feed2exec are doing okay, mostly because they were written in Python 3 from the start, and the latter has extensive unit tests. But they do suffer from the occasional bitrot (the latter in particular) and need constant upkeep.) Now that I barely have time to keep up with just the upkeep, I can't help but think all of my projects will just die if I stop working on them. I have the same feeling about the packages I maintain in Debian.

  • What Can AI Teach Us about Bias and Fairness?

    As researchers, journalists, and many others have discovered, machine learning algorithms can deliver biased results. One notorious example is ProPublica’s discovery of bias in a software called COMPAS used by the U.S. court systems to predict an offender’s likelihood of re-offending. ProPublica’s investigators discovered the software’s algorithm was telling the court system that first-time Black offenders had a higher likelihood of being repeat offenders than white offenders who had committed multiple crimes. They also found only 20% of the individuals predicted to commit a violent crime did so. Discoveries like these are why ethical AI is top-of-mind in Silicon Valley and for companies around the world focused on AI solutions.

  • How to Add Time Delays to Your Code

    Have you ever needed to make your Python program wait for something? Most of the time, you’d want your code to execute as quickly as possible. But there are times when letting your code sleep for a while is actually in your best interest. For example, you might use a Python sleep() call to simulate a delay in your program. Perhaps you need to wait for a file to upload or download, or for a graphic to load or be drawn to the screen. You might even need to pause between calls to a web API, or between queries to a database. Adding Python sleep() calls to your program can help in each of these cases, and many more!

  • LLVM Clang RISC-V Now Supports LTO

    With the recent release of LLVM 9.0 the RISC-V back-end was promoted from an experimental CPU back-end to being made "official" for this royalty-free CPU ISA. Work though isn't over on the LLVM RISC-V support with new features continuing to land, like link-time optimizations (LTO) most recently being enabled within the Clang 10 code. Within the latest Clang code this week, LTO (link-time optimizations) are now enabled for Clang targeting RISC-V. LTO, of course, is important for performance with being able to exploit more performance optimizations by the compiler at link-time.

    This is another huge update after its initial release in 2013 and catches up with the latest developments (a lot happened!) since the last big update in 2017.
