Building k9s for Linode With Bubble Tea

Wed, 09 Sep 2026 21:22:00 -0700

A lot of my day is spent in k9s. Sometimes I need something from the Linode side of the house. Maybe it’s a node that won’t boot, a volume nobody cleaned up or the kubeconfig for a cluster I just made. Then I’m back in a browser tab or typing linode-cli incantations. I wanted the k9s workflow for the Linode API itself:

: to jump to a resource type
/ to filter
single-key actions on the selected row
Enter to go deeper

That turned into linode-tui. It’s a Go TUI built on Bubble Tea, linodego and urfave/cli v3.

ephemerd: One Daemon, a Fresh Runner Per Job, Every OS

Tue, 18 Aug 2026 21:05:00 -0700

I have CI that needs Linux amd64, Linux arm64, Windows and macOS. GitHub-hosted runners for all four get expensive fast, especially the arm64 and Mac minutes. Self-hosted runners fix the bill and create a different problem. A stock actions/runner on a box you own runs whatever the workflow says. It keeps whatever the last job left behind. And it’s one fork PR away from somebody running code on your LAN.

Stop Ctrl-C-ing Your tail -f | grep

Sat, 20 Jun 2026 20:31:00 -0700

Here’s a loop I end up in all the time:

tail -f app.log
something scrolls by that looks wrong, Ctrl-C
tail -f app.log | grep ERROR and wait for it to happen again
decide I also want to drop the health checks, Ctrl-C
| grep -v healthz and wait again

Every filter tweak throws away the stream and every line that already went past. I got tired of it and wrote tail-gunner. It’s a tail replacement that you can promote into a filtering TUI with one keystroke. You can drop back out of it without the stream ever stopping.
