When someone asks me what the #Fediverse, #Mastodon or #ActivityPub is I'll use this illustration from UNIX Review, April 1985.

Wrote new article — about how to use some ThinkPad-specific keys with FreeBSD. Most of the Fn-keys and volume control separate keys could be uses "as is" — the OS passes the proper and well-known keycodes (like XF86audioMute, etc) to the X server. But some keys needs some "black magic" (devd and acpi_ibm kernel module).

The bonus point — how to use ThinkLight to signal about low battery level with Morse code

I nerd sniped myself and wrote a monster article doing a code commentary of /etc/rc from #OpenBSD 7.8: https://overeducated-redneck.net/blurgh/openbsd-init-system.html

I learned a ton of my base sysadmin skills from studying init(8), and decided to produce a modern version of that (I learned in the 90s).

Also, I have armored my webserver against all bots, and fedi is the only place I syndicate. Boosts are appreciated.

System Administration: Week 7: DNS, Part II

In this video, we dissect DNS lookups performed on our EC2 instance, then discuss just how a caching resolver performs the lookup, moving from "magic happens here" to the below visualization.

I have deployed and run infra since the noughts, through some wild turns in geo/techno-political history, and will say that now more than ever, #selfhosting is an act of resistance.

Depopulate. Defund. Disempower.
