extremely feb 2026 energy but I just published a jj workspace manager pando uses OS copy-on-write and stores workspace info in one place so I can run multiple throwaway explorations on my machine without too much ceremony dl it, rip it, rewrite it in zig: github.com/laulauland/p...

this is so painful to read, i love it github.com/stephenturne...

If anyone would be down to co-organize a reading club for this in Amsterdam area, hit me up

I first tried to read this book in 2018 and couldn't make it through because I thought it was too hard. 8 years later it's the only book I recommend every developer reads, and I had the chance to review the 2nd edition. Join a study group, give it a read.

PSA no model drops this week but the new Designing Data Intensive Applications (aka the Hog Book) is out on paperback

marimo notebook making my m1 pro go brrr

“Intelligent drum & bass” is such a weirdly judgemental name for a music genre

vacation reading on computational literacy: finding diSessa’s framing “building tools to build intuition” especially relatable lately (book: “Changing Minds: Computers, Learning, and Literacy”)

any time codex/claude makes an elaborate awk/jq/sed sequence to debug a large stream of text I say a little thank you prayer in my mind for the unix geeks who have practiced this craft long before we had the magic token machines

I've had a brief Nix era in 2023/24 that I since reverted from due to the usual Nix stuff (obscure errors, one particular way of doing things, pain of making changes mid-flight) I am now very tempted to return to it - most of the stuff that was a pain to deal as a human dev is excellent for agents

with all the buzz around harness engineering and self-driving codebases, i keep returning to this text: petevilter.me/post/datalog...

everyone’s exploring different agent coordination messaging platforms when all we should do is get them to send diff patches over email git send-email exists for a reason

prototyping co-drawing with Gemini Flash 3 at Google in these demos "thinking" is disabled, which makes the model return tokens very quickly (all videos are realtime), and I find these rapid responses pretty good for the use-cases I'm experimenting with, like: executing simple diagrams ...

sunday evening stream, hacking on pi extensions, trying this out for the first time hiiii www.twitch.tv/laulau_land

Working on pi extensions

ast-grep scan will continue until morale (and codeslop) improves

just released a small update to jj-hunk - programmatic hunk selector for your jj-using agent New: -r flag. Split any revision, not just your working copy. support for YAML specs stable hunk IDs you can install it with: cargo install jj-hunk npx skills add laulauland/jj-hunk

fine, here's another one: shell completions for running ! comands inside prompts. Hooks into your shell completions directly (unless you're on zsh, which idk why you'd be there) npmjs.com/pi-shell-com...

pi (a very good and very shitty coding agent from @mariozechner.at) has a very powerful extension system that I already raved about. Now that it supports npm/git-based installs I published a couple of mine that I've been using daily

<niche-CI-content-alert> wild that the most common standardized format for reporting test results is a *loose* standard JUnit XML really hoping this changes in 2026 now that we're mostly focused on reviewing/reporting on code </niche-CI-content-alert>

getting to the point where I'm really liking the experience of Tatami - a GUI I'm building for jj - uses jjui/vim-style keybindings for navigation - has overview and detail screens - fast! Uses @tanstack.com DB to interface via @tauri.app IPC - uses diffs.com of course

needed a tool to make it easier for agents to reorganize commits and hunks into logical narratives that make it easier to review code jj split is great but requires interactive TUI that's still a tricky territory for Claude so here's jj-hunk - programmatic hunk selection for jj

I wrote up how my workflows with agents and coding evolved over 2025 gearing up for the first week of work already but if you're still in the mood to read blog posts - here you go: laulau.land/working-with...

it's atuin wrapped time! story of my 2025 shell is that I adopted jj halfway through the year (you can see lg - lazygit - decline) and mostly switched projects from pnpm (shorthand: pn) to bun

brb adding a claude code hook that exits with error 2 the moment it outputs "comprehensive"

ok so raw thoughts while exploring OpenAI's new Apps SDK the difficult thing right now is with the existing tooling you have to run two servers: one to serve your assets, one to drive the MCP server logic

launched mcp-lite today: github.com/fiberplane/mcp it's a lighter, minimal library to create your MCP servers in TypeScript that can work on any runtimes and can work with any Standard Schema vendors

if you're publishing an npm library today - what is the standard to inform coding agents about its API (is there)? Something like AGENTS.md but that you can embed in the package.

git remote add @tangled.sh

a dear friend of mine launched an independent label for experimental music today and I helped make a fun website for it first album is very very good, go pre-order: www.glinted.info

trying to use atproto/bsky libraries in Cloudflare runtime is not having a great Sunday hacking time

today's discovery has been being able to easily locally integrate changes from 3-4 different unmerged PRs and one local branch. jj definitely makes for a *really* good review tool

ok, `jj` is very nice
