Arch Linux package cleanup notes

2 min read

Cleaning up your arch packages is a bit of a chore. The key document listing the pacman invocations you will need is pacman/Tips and tricks (ArchWiki).

The basic flow I use is:

  • list explicitly installed (-Qe),
  • remove (-R) any that I don't explicitly want,
  • remove orphans (pacman -Rns $(pacman -Qtdq)).

I always end up with a bunch of KDE packages installed which I find annoying because it makes my upgrades go a lot slower due to their size and frequency of update. They must be pulled in by one of my explicit installs. Time to generate some dependency graphs:

Pactree reveals that krita is pulling in all those KDE packages. Well, I want to keep krita so I guess I'll put up with them :D.

Portland Friends: I'm Leaving Town!

1 min read

I'm just in Portland this week and the last week in June!

I'm scheduling several opportunities for group hangouts, or hit me up for a bike ride/park time/whatever.

After that I'll be gone at least for the Summer/early Fall travelling and visiting my mom in S Oregon, possibly much longer as I'm considering living abroad in Europe for awhile.

Heat Welding Acetal

TIL that Acetal plastic (aka POM, Delrin), as used in the fracture-prone Kinesis Freestyle2 pivot tether, which is notoriously-difficult to bond, can be heated-tool welded using a simple soldering iron.

Yesterday I installed https://github.com/acrisci/i3-style and now my HCI has PURPLE HIGHLIGHTS! It's really quite nice. Also used the builtin rofi-theme-selector to set a nice matching rofi theme.

Odroid SHOW2, an Arduino compatible with a 2.2" TFT LCD onboard!

Hardkernel's ODROID SHOW2 combines nicely with their Weather Board 2

I'm going to hook one up to the Shinyei fine particulate sensor I got off ebay to make a home environmental quality monitoring station.

I'm working on setting up a new hosting node, using Kubernetes, but till then my only non-deprecated public-facing app hosting node is the one edrex.pdxhub.org live on: a 1GB @CoreOS / @indiehosters / https://libre.sh VM on @DigitalOcean.

Libre.sh is a nice containerized hosting automation script but ultimately a dead-end because it isn't @Kubernetes-based. Fortunately it offers a very straightforward app migration path because everything is a @Docker container with a standard structure.
