I tried to make that post land on April 1st to make it more confusing but got busy and messed up. For the sporadic peruser, every other day is April Fools day anyway. (:

Another systemd tip is the analyze timespan and calendar commands for timers. They’re good for planning out timer sequences or explaining them to the microsecond.

I tend to use Weston (also as a kiosk) in Wayland and then Awesome Window Manager in X11. I’ve been scuttled back into desktop/wm agnosticism, but temptingly Weston has a Lua shell now?

Awesome is awesome and there’s also some that’s not awesome but awesomely compatible in Wayland. If you don’t know what’s X11/Wayland, may you continue to have a wonderful day.

I guess abbreviations are fun? I clipped my terminal vim abbreviation abuse before. Automated abbreviation expansions are surprisingly interesting but tricky with the edge cases. I cooked up super crude expansions for feeds coming into that “event log” too.

If anyone’s getting into nginx look into nginxinc/crossplane. That parser is particularly good if you’re trying to analyze or do sophisticated stuff with a huge nginx.conf. I have this one installed in my playground, here’s a quick and dirty demo:

I helped someone with a tmux config. It’s been a while since I’ve used tmux but I’ve since realized it’s better to copy paste tmux list-keys into tmux.conf and reset all shortcuts (for debugging).

tmux list-keys

The help menu (tmux list-keys -N) displays shortcuts with bind-key -N "description".

Sandboxing in systemd? I would’ve shown my (somewhat manual) method but then I was strolling through the GitHub and saw shh (systemd hardening helper). It uses strace to generate suggestions. You’ll need to be extremely careful, playing inside a sandbox summons debugging hell. I tried it briefly.

This graph is from Grafana. It’s moreso for developer operations. I used to use qtiplot for random stuff, but nowadays I use gnuplot for scriptability (not GNU, see demos). Then, there’s Microsoft Excel et al.

The interest in TUIs online is high. In the real world you tend to be constrained and blindfolded by the tools available/allowed. Filtering is peculiar though.

See how the terminal/editor splits? Filtering makes them kiss? Commands that input|output (pipe) work best (compilers, transpilers and code generators). The meta is the limit.

File name, spelling, and dictionary completion exist too. This is tortured, but combining them makes a meta point? The “meta” is hard to convey, but completion doubles as a way of finding, changing, and passing keywords around. Terminals are fair game too. That’s basic completion in a nutshell (minus the magic).
