- SignalsTalk[1] to study quantitative trading signals and algorithms, for my own curiosity.
- YCVerify[2] for verifying YC companies and founders. No one else is using it yet.
- Content Credentials API[3], to find the signatures of AI generated content.
I'm also working on:
- A search engine for online ads.
- A way to track grocery item prices from receipts using LLMs.

> My most used tool I have is a note taking web app that automatically saves markdown files to S3. The most important feature I added was a little button that would automatically make a note for the current day, and put it in the daily notes folder, all sorted and organized. I also have full text search which is very helpful for finding old notes. I have a very similar thing, mine uses a dropbox folder as a backend s…
Sounds like you'll be better served by obsidian. The free plan covers all those use cases and more

What do you use for valve automation? Is it a commercial or custom part? I've been wanting to do the same myself, but I hear there's all sorts of quality issues with automatic valves.
I originally bought some solenoid valves to experiment with, but ended up simplifying my approach. I use a submersible pump that is plugged in to power. I can just automate turning on/off power to that outlet (I have two TP-link / Kasa HS300 strips). The nutrients / water are in a tank below the tray of plants, so when the power is "off", gravity brings the water back through the pump into the tank again.
1 is a sort of a virtual notebook where I put things I want to remember. Things like guides for setting up new services on top of that platform service. Or random 1 line commands that I don't quite use enough to remember but still need to. Page content in this app is stored in encrypted Markdown files, the metadata (ie the title, publish date, etc) is stored in a local MongoDB instance. It has a feature where you share individual pages publicly if you want, but otherwise pages are viewable only by their original creator. Server is Go, frontend is Angular 10. I don't remember how long it took to build as it started as something else and I kinda reset the development half way through. Probably a few weeks, but I also wasn't constant working on it, so probably longer.
2 is a thing I built out of frustration with my self-hosted Gitlab instance constantly OOM-ing the VM it was on and crashing. It has like a tenth or less of the functionality of Gitlab, but also uses substantially less memory and CPU and does exactly what I want so hasn't seen much if any further development. Also Go for the server and some even older version of Angular for the frontend.
I have a utility (dklocs) that'll turn git-formatted diffs into location-prefixed changed lines. It lets me do things like `git diff master | grep thatThing | vim - -c cbuffer!`. I built it for me (and probably use it multiple times a day) but threw it on github (along with another tool for intersecting a diff with code coverage that I don't think I've used since the motivating use case - where it did prove helpful).
I don't know if it quite counts as "creating software" but I've got some scripts and configuration to maintain separate context in named screen/tmux sessions, setting shell variables and aliases, adjusting the prompt, starting in some particular directory. Most useful there is segregating history by context, so ctrl-r when I'm coding doesn't step through system administration stuff.
I have a general project to decompose applications into utilities, and a pattern for dealing with the long-running bits that's been somewhat successful. I once wrapped up libpurple in a client that worked that way, and (in a separate project) it's how I get errors from `cargo watch` into vim.
Some differences include no naming rules (a lot of my note titles have a colon) except uniqueness, custom clusters so my knowledge graph is manageable.
I’m going to add different note types (i.e. not every note is .md, but have .csv and .ical as well) that can be expanded and linked within a note.
It’s written in React, hosted on AWS (so not an Electron app… yet), and CodeMirror for the editor.
I’ve spent probably 100 hours making it so far.
