From the workshop
Short answers to practical questions from building things, each with the config, command or code that worked.
The checklist I edit my drafts against runs in two places, a page that marks the lines in your browser and a Python script for files and agents. The commands, and how to read the output.
A release job checked five files against a saved patch, and another commit that moved the lines around its changes made the patch stop applying. Comparing only the added and removed lines kept the check strict about the job's own changes.
An image build filled a 19 GB root volume to 100%, and docker builder prune -f freed 1.44 GB of unused build cache with images and volumes untouched. The safe prune, and the two that delete what the next run needs.
A directory junction gives a second worktree the main checkout's packages with no second npm install. Delete the junction before git worktree remove, because with it in place git deleted the packages it pointed to.
Rubric's summary prompts said each summary was "for Hrih News", and 65 of 1,027 summaries named it, three crediting another site's post to it. Once the name was gone, none of the next 209 did.
An endpoint at src/pages/llms.txt.ts writes the file from the same lists as the RSS feed, so drafts never leak and every deploy keeps it current. Expect little traffic from it, one claude.ai visit in two weeks.
A scheduled task runs with nobody there, and in Auto mode the permission classifier blocked its deploy.sh as "Production Deploy". Schedule up to the commit, push to a branch, and send yourself the one command to run.
On a 40 GB disk, the Ubuntu Server installer made the root volume 19 GB and left the rest of its volume group free. One lvextend gives the volume and its ext4 filesystem all of it, while mounted.
My Bluesky handle is hrih.si and Rubric's is rubric.hrih.si, two accounts with a TXT record each. The exact records and how to check them.
Each job is a one-shot container started by a systemd user timer, with no root and no always-on scheduler. The units, the timer and the install.
One static WebFinger file and two headers let people find a Mastodon account at your own domain. The file, plus the Caddy and nginx config.
X's API charges $0.20 for a post with a link. Buffer's free plan posts to X and LinkedIn from code through its GraphQL API. The calls I use.
A git-ignored folder existed on my PC and not in the container, so tar failed, the job said done and the live check said live. The three fixes.
