Because of a HN post(https://news.ycombinator.com/item?id=44421776), I've got a ton of feedback for Ensō: my writing app for flow/stream of consciousness writing. So, I'm wrapping up the release and adding good support for non-Latin, esp. RTL languages (Arabic, Persian, Hebrew) + pinyin and Japanese input methods.

Recently I also made a font for it! https://untested.sonnet.io/notes/433-how-to-make-a-font-that...

I'm also thinking about organising the usage patters, because over the past few years I've collected a few interesting groups: mental health focussed users, script writers, neurospicy folks, bloggers, squirrel enthusiasts. I'm thinking about this here: https://untested.sonnet.io/notes/how-people-use-enso/

I'm continuing the work on Cellm, an Excel extension that let's you call LLMs in cell formulas like =PROMPT(A1, "Rate the sentiment of the customer feedback as positive, neutral, or negative"), and then drag the formula down to apply the same prompt to thousands of rows. I built it after my girlfriend had to manually classify 7,500 research papers. Cellm automates that kind of repetitive work.

Since we added MCP and the use of structured output to "spill" multiple return values into adjecent cells, it is the quickest way I know of to monitor competitors blogs everyday before my 09:00 meeting. And also the quickest way I know of to test new AI models. I have a sheet with SimpleQA, MMLUPro, or GPQA Diamond and testing a new model is a matter of adding a new column. The whole idea is to enable normal people (like, non-techies) to automate manual, repetitive tasks with AI like programmers routinely do.

I recently built a site for guessing house prices. I thought I'd be done with it in a week. Over a month later I still have a ton of things to work on.

You can at least play some games now though:

Enjoy. And yes that really was my wife playing one of the games for the first time in the video ;)

My roommate and I are still working on Tornyol, our mosquito killing drone! It uses ultrasonic sonar to detect mosquitoes, and missile control theory to ram into mosquitoes and grind them in its propellers. Our target platform is a 40 grams tinywhoop so it’s safe to fly everywhere and makes almost no noise :). A Roomba for mosquitoes! The main plus compared to traditional systems is that a drone can cover an enormous…

Hadn't seen this before, this is awesome! I lived in Cameroon and Kenya briefly doing some consulting work and mosquitos still wreak havoc across the continent (and now living in DC I wouldn't mind having one of these in the summer for my place). I'm curious if you're also thinking about defense applications -- I would imagine that a super low cost drone that could help take out a shahed or other Russian drone that a…

Glad to hear we could be of help! Some of our tech could be used for defense, but traditional defense companies and ukrainian startups already do low-cost shahed interceptors.

A web app DSL that looks like: GET /hello |> jq: `{ world: ":)"}` pipeline getPage = |> jq: `{ sqlParams: [.params.id | tostring] }` |> pg: `SELECT * FROM pages WHERE id = $1` |> jq: `{ team: .data.rows[0] }` GET /page/:id |> pipeline: getPage WIP article that explains more: https://williamcotton.com/articles/introducing-web-pipe I would love feedback!

I really like it. I particularly like that you've resisted the temptation to include SQL itself or the jq queries in the DSL.

The validation piece makes it feel a bit a bit like the Rails mindset for people who work better in FP.

I'd make a could of suggestions for the docs: Maybe a bit more discussion of how we'd test our webpipe code. I see why you've called them 'middlewares' but, maybe the term 'macros' or 'pipeline functions' might avoid confusion with express/connect middlewares

I've been learning systems programming for a while and recently I discovered kilo[0], which inspired me to start building my own editor[1]. Not sure how far I'll go, but hopefully it will be usable -- how fun would it be to build another project of mine using my own editor?

I've been working on a little utility to transfer files between two computers using QR codes: https://github.com/cibyr/qftf It's kinda like Magic Wormhole without typing. It uses iroh for the p2p networking - on both ends, and also in the little web app that you use to scan the QR codes and start the transfer.

Have you seen https://file.pizza/ FilePizza? Similar concept using WebRTC

We're supposed to use AI at work, which has been very 50/50 for me as expected.

Last month I decided to take a subscription of my own for Claude Code to use in my personal time mostly for practice and educational purposes.

So the past few weekends and the occasional week night I've been vibe-coding a game for iOS/MacOS using Swift and SpriteKit.

I have some experience with Swift previously but not at work, so it's extremely experimental for me. However it's been going pretty well. Most of the hang-ups are Xcode configuration issues.

It's interesting to poke Claude a bit and discover what it's actually decent at and awful at.

Gameplay mechanics-wise it's been able to implement things as requested generally without problems.

UI elements like menu screens and such it has been almost completely unable to do no matter what prompt I give to it.

It's safe to say I would never call the codebase professional quality. However, the base game has been implemented well enough to play without bugs and I've been solidly impressed.
