I'm redoubling work on IronCalc (https://www.ironcalc.com), a spreadsheet engine. Actually considering going full time on what it begun as a side project.

#112I'm writing an easy to use APM platform in a single executable (plus the database).
I tried self-hosting Sentry recently and found out there are a lot of moving parts, which makes sense for their scale and use case.
I was wondering if I could build something small and not multi-tenant. So I started experimenting with writing a server (in Go) that collects OpenTelemetry data and inserts into Clickhouse, an API for retrieving data/statistics (P95 in a time range, etc...), and a frontend (React.js) that displays them. All of this in a single executable file (yes, including the frontend, but not including Clickhouse).
This is all very new to me so I'm learning Go, Clickhouse and OpenTelemetry at the same time.

#113A new YouTube app/player, for my kids.
It allows us to control the algorithm. It’s all LLM translating to YouTube search queries under the hood.
Visually it looks the same. The suggested videos come from predefined buckets on topics they love.
E.g. 33% fun math, 33% DIY engineering, 33% creative activities.
Video recommendations that have a banned word in the title/desc don't get displayed e.g. MrBeast, anything with Minecraft in it, never gets surfaced.
For anyone interested in using it, send me an email.
I'll put you on my list. And you can contribute ideas to our community Google Doc.

For the last few weeks, we have been working on catching up on features for vibe coders (prompt -> project), but now we are back to our strengths (visual editor and new beautiful UI libraries for Tailwind CSS, Bootstrap, and more).
We realized there are just too many apps for vibe coders, and it would be better to work on something unique that we are really good at!

#115I've been collecting and digitizing vintage print advertisements and publishing them ( https://adretro.com ). I have tens of thousands of ads in the collection and it would take me many lifetimes to complete, but I've been using AI to extract and catalog the meta data. I can get through about 100 ads/day this way. One of my favorite ads, a computer from 1968 that "answers riddles": https://adretro.com/ads/1968-digi-c…
That’s really cool.
Thank you!

#116I'm collecting a collection of PEG grammars here https://mingodad.github.io/cpp-peglib and Yacc/Lex grammars here https://mingodad.github.io/parsertl-playground/playground both are wasm based playgrounds to test/develop/debug grammars.
The idea is to improve the tooling to work with grammars, for example generating railroad diagrams, source, stats, state machines, traces, ...
On both of then select one grammar from "Examples" then click "Parse" to see a parse tree or ast for the content in "Input source", then edit the grammar/input to test new ideas.
There is also https://mingodad.github.io/plgh/json2ebnf.html to generate EBNF for railroad diagram generation form tree-sitter grammars.
Any feedback, contribution is welcome !

#117Testing the limits of vibe coding. Created a programming language 100% via prompting a o4-mini-high, but did carefully review the code. https://github.com/ryanmcdermott/spress

#119Working on expanding https://iplocate.io - an IP geolocation and threat data service I've worked on since 2017.
I've found it really satisfying to solve the data challenges that come along the way, from "where on earth could this data come from" to collecting, storing, parsing, validating and serving constantly. It's also - by nature - something that's never going to be "done". There's always something to improve. I love it!
We now offer more types of data (ASN/whois, proxy/threat detection, so on) than most other providers, more accurate and more frequently updated, at a tenth of the cost, which is something I'm really happy about.
For anyone interested, you can make 1,000 requests day free, or reach out if you have an open source/public interest project for an unlimited key or access to the data.
I'd also love to hear any suggestions for additional data types to add.

Is there a way to contribute? I have some old National Geographics I bought for 10 cents each a number of years ago. The old ads are one of my favorite things in every magazine.
