A “code index” tool that finds symbols in a codebase and creates a single table sqlite database for querying. It’s my second month using Claude Code, and I see a common pattern where Claude tries to guess patterns with grep, and often comes back with empty results. I’m writing the tool to prevent these fruitless searches. Using tree-sitter to parse the AST and add the symbols and what they are (function, class, argum…

This is why codepathfinder.dev is born. It underhood use tree-sitter to search functions, class, member variables and pulls code accurately instead of regex.

I started using it like tool call in Security scanning (think of something like claude-code for security scanning)

Give it a read if you're interested:

Happy to discuss!

I am still [0] working on trying to recover who I was before whatever -- a couple of years ago -- rendered me progressively unable to concentrate on anything. Last month was an improvement. This month I can't concentrate for long and I distract very easily, but I seem to be able to do more with what I have, A small sense of ambition that I might be able to do bigger things, and might not need to drop out of tech and…

Bests!

I found a neat way to do high-quality "semantic soft joins" using embedding vectors[1] and the Hungarian algorithm[2] and I'm turning it into an open source Python package: https://github.com/olooney/jellyjoin It hits a sweet spot by being easier to use than record linkage[3][4] while still giving really good matches, so I think there's something there that might gain traction.

This is very cool! Thanks for sharing.

Currently a one-man side project: https://laboratory.love Last year, PlasticList found plastic chemicals in 86% of tested foods—including 100% of baby foods they tested. Around the same time, the EU lowered its “safe” BPA limit by 20,000×, while the FDA still allows levels roughly 100× higher than Europe’s new standard. That seemed solvable. Laboratory.love lets you crowdfund independent lab testing of the specific p…

1. An example result is "https://laboratory.love/product/117", which is a list of chemicals and measurements. Is there a visualization of how these levels relate to regulations and expert recommendations? What about a visualization of how different products in the same category compare, so that consumers know which brand is supposedly "best"? Maybe a summary rating, as stars or color-coded threat level?

2. If you find regulation-violating (or otherwise serious) levels of undesirable chemicals, do you... (a) report it to FDA; (b) initiate a class-action lawsuit; (c) short the brand's stock and then news blitz; or (d) make a Web page with the test results for people to do with it what they will?

3. Is 3 tests enough? On the several product test results I clicked, there's often wide variation among the 3 samples. Or would the visualization/rating tell me that all 3 numbers are unacceptably bad, whether it's 635.8 or 6728.6?

4. If I know that plastic contamination is a widespread problem, can I secretly fund testing of my competitors' products, to generate bad press for them?

5. Could this project be shut down by a lawsuit? Could the labs be?

AutoDocument: https://github.com/TomMalkin/AutoDocument

Imagine your basic Excel spreadsheet -> generating document files, but add:

- Other sources like SQL queries

- User form (e.g. "Generate documents for Client Category [?]")

- Chaining sources in order like SQL queries with parameters based on the user form

- Split at multiple points (5 records in a csv, 4 records in a sql result = 20 generated documents)

- Full Jinja2 templating with field substitution but also if/for blocks that works nicely with .docx files

- PDF output

- output file names using the same templating: "/BusinessDrive/{{ client_id }}/Invoice - {{ invoice_id}}.pdf"

All saved in reproducible workflows (for example if you need to process a .csv file you receive each morning)

We're building a repairable and more sustainable ebike battery at https://infinite-battery.com :)

Any chance you'll take a look at power tools next? There are some Amish people who rebuild Dewalt, Milwaukee etc battery packs. I'd like a repairable/sustainable platform where I can actually check the health of the battery packs and replace worn out cells as needed. To give you an idea of the market, original batteries are about $149, and their knockoffs are around $100.

Heck, you can get a 50-foot extension cord for $60!

Battery-powered hand tools are heavier, clumsier, generally of lower quality, less power and are less long-lived than AC-powered tools.

To be honest, there's a little Amish in me: I have hand-powered tools as backup for all my AC tools.
