Musings: libxo, Python code quality, and Linux kernel shenanigans

I’ve been inspired to actually make this in to an actual bloggy journal thing instead of just writing occasional long-winded well thought out articles. I still want to do long-winded well thought out articles, but the entire reason I got this thing in the first place is to share my knowledge and experiences with the world. Might as well.

Caught up on the backlog of happenings on the freebsd-current mailing list. Lots of people are upset about libxo, including myself. May mean a Linux migration in my professional future. Disappointing, especially since there is a lot of opposition, but it’s understandable that it’s going forward anyway. Juniper pays to keep the lights on at the FreeBSD foundation, so they have a lot of pull. Sad to see they don’t really care about the community or what we have to say.

Looked harder at GCC 5.1 code output. Then looked harder at switching default compiler from GCC to Clang on Gentoo. 😉 It’s not all there yet but it seems to be improving every day. Looking forward to trying out a Clang-compiled kernel if that patchset advances.

Played with Pylint and Pyflakes. Ran it on a few of the projects I work on and a few of the ones I write with Elly. PyIRC 3 got a rating of 8.5 out of 10. Really impressive. I hope to show Pylint to the people at work in the coming week and improve the quality and process there too.

Tried playing Minecraft. Already felt a bit dizzy before playing, so that was a mistake. Logged off after about 20 minutes from the ill feeling. Perhaps tomorrow.

Found out about a lovely years-old DoS vulnerability in the Linux kernel’s UDP stack. Ran netstat on my servers to make sure they had no UDP listeners. Not sure what to do about the Minecraft server, perhaps the DDoS protection we already have on it is good enough.

Read a hilarious article comparing the Pentium 4 Northwood to various new CPUs, where the AMD “accelerated” notebook CPUs performed worse. I can’t believe AMD has gone so downhill that a Pentium 4 from 2002 can spank its brand new designs.

Decided to start configuring a 4.1-rc7 kernel for my laptop. 3.18 is so old (by my own standards) and I really want to get off of this line since my checkout is still affected by that stupid exit race bug which sometimes causes Firefox to die. Found an interesting knob, CONFIG_EXT4_ENCRPYTION, which is apparently the same encryption stuff Android “M” will be using. Pretty neat but seems useless for my needs. Might try it on the Pentium II for the hilarity.

Tried to tinker with the internals of OS X Server 5.0 beta 1 before bed, but it’s compressed with a weird algorithm (ADC?) that none of my Linux utilities can break open. I’ll need to investigate that more tomorrow.
