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...

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

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

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

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.

Is there a way to programmatically load some context into Claude Code using CLAUDE.md or hooks? Specifically need it to load the WezTerm's pane id where I have a dev server running so that it can independently look up its output using `wezterm cli get-text --pane-id <pane-id>`

one kind of hilarious thing of trying to combine neverthrow with Cloudflare's Workflow primitives is having to write wrappers that throw..neverthrow-returned errors as Cloudflare Workflows uses caught errors to trigger retries there's probably a better way to do this...

this is the code in the image:

/**
* Wraps a neverthrow Result-returning function in a WorkflowStep.do call.
* Throws an Error to trigger a retry by default, or a NonRetryableError if classified as fatal.
*/
async function runStep<T extends Rpc.Serializable<T>>(
step: WorkflowStep,
name: string,
config: WorkflowStepConfig,
fn: () => Promise<Result<T, TugboatError>>,
isFatal: (error: TugboatError) => boolean = () => false,
): Promise<T> {
return await step.do<T>(name, config, async (): Promise<T> => {
const result = await fn();
if (result.isOk()) {
return result.value;
}
const error = result.error;
if (isFatal(error)) {
throw new NonRetryableError(error.message);
}
throw new Error(error.message);
});
}

Had a whole lot of fun giving my first conference talk at @squiggleconf.com last year. The crew was very supportive and the vibes were immaculate. If you thought “maybe i should try giving a talk”, then saw a CFP, got excited, and then later thought “ehh idk” then you should think again and apply.

some interesting historical context re: stories of "chatGPT-induced psychosis" is that when the radio and telephone were invented, there were similar reactions — some people believed they could tune their radio to the frequencies of heaven or received instructions from the dead via the telephone
