Thanks - planning to open source it (at which point the link will work :) until then should probably hide that I guess…

Show HN: Diffswarm – GitHub-style review and workflow for any unified diff

jchap — Tue, 06 Jan 2026 02:25:13 +0000

Pipe the output of a `diff` command to Diffswarm to get back a persistent URL that contains the diff with workflow, comments, search, etc. Basically some of the helpful features that Github offers on PR diffs, just available for any arbitrary diff.

I wrote this tool to use at work for documenting snapshot diff triaging, and also used it to help with the same thing on a couple Ty PRs. Example: https://diffswarm.dev/d-01k2gknwyq82f6x17zqf3apjxc

Show HN: Magic-markers – control a smart bulb with crayola markers

jchap — Tue, 30 Sep 2025 12:03:50 +0000

i made this for my niece for her 3rd birthday. it was inspired by this reel: https://www.instagram.com/reel/DIE2O59Svcz/?igsh=MXNnbmJsZWR.... the main difference (i believe) is that this is entirely self-contained and does not require integrating with a smart home system. the bulb connects directly to a wifi network on the nanoc6, and the nanoc6 posts commands directly to the tasmota command endpoint on the smart bulb. this was a lot of fun to build :)

New comment by jchap in "Ask HN: Workflow Orchestration tools?"

jchap — Thu, 03 Apr 2025 19:58:50 +0000

Are there any (simple) tools out there where the API contract is like:

- POST a statechart to something to kick it off/validate transitions/log events, schedule waits/etc

- receive POSTs (webhook-like) back to a handler endpoint to actually execute side effects

The SCXML spec defines stuff that supports this really well (ie the send/invoke tags)

Closest things I’ve been able to find:

Stately/XState

Temporal

AWS Step Functions

Step functions probably the closest to what I'm looking for but is the task token thing the only way to “receive” events?

Doc said cholesterol is high (and got some other risk factors), sadly having to axe (or modify) some meals in the rotation. Made a little tool to help and to make it slightly more fun for myself.

If any lawyers, nutritionists, cardiologists, or FDA regulators see this and it’s saying something wrong or bad please tell me.

this is a great idea, going to update the docs. also, regarding dark themes, you can control the text/background color via query params:

Show HN: Munter factors for your uphill ski days on Strava

jchap — Mon, 16 Jan 2023 03:25:34 +0000

My friend is training for the Grand Traverse and using the Munter method in his pacing estimates.

Last weekend I hacked together a Strava app that calculates Munter rates from your activity data.

Connect your Strava account, and whenever you upload a "Backcountry Ski" activity, it'll put the rates at the bottom of the activity description.

Made a "Club" on Strava for feedback/suggestions/feature requests/etc: https://www.strava.com/clubs/1106227/discussion

Cheers!
