I'm working on Trebella [0], a tool to help classical music students structure their practice sessions more effectively. I tried to build something similar ~10 years ago in the form of a more interactive music game, but felt like it wasn't actually that helpful for intermediate and advanced students. So this time I'm doing it in collaboration with actual music teachers and building a tool that actually helps me learn…

The thing I love about software, is you occasionally get this holy crap moment and I got that when I had to be away for 2 days and had an orchestrator agent run this for multiple days, without drifting too much. Maybe a little overenginneered but thats whatever. I spent about an hour planning, auditing the plan and adding more so the top-level milestone and inner sprints were pretty well defined or included the relevant context locations for each task. then watching the orchestrator launch a multi-day multi-agent workflow, was quite amazing.

#954It used to be a mashed together set of PHP scripts that used the filesystem for data storage/organization, and I had to write raw HTML for my blog posts. A few years ago I rewrote it in Flask (Python), and designed it to use a database.
One piece of functionality I never got around to copying from the PHP version though, was author biography pages. Early on, my blog was designed such that I could publish things written by other people, because a close friend of mine expressed some interest in having his stuff on it. Thing is, he never got around to writing anything. So when updating to Flask/Jinja, I didn't implement this (I did implement minimal authorship code, so the database already stored author identities, and there was HTML to show author name).
I've been in talks with another friend though about doing the same thing, and I mistakenly told him it was already ready (I thought it was), only to discover the lovely URL `/author/NOTIMPLEMENTED`, so I'm finally creating this endpoint and page template.
I'll also have to update the database schema to include licensing, because the current site always reports the same CC license (the one I chose for all my posts).

If anyone wants to use the code, there's a Docker image too, and you can easily-ish replace the branding with your own.
Outside of that, for the last few months I've been working with someone on a web app for uploading videos to a server/database.

#955We make math a joy to play with and spark wonder through experience.
Prime numbers literally come to life, sprouting legs and personalities, as signals from the spirit world animate them; but when your best friend is portaled to the spirit world and NullCorp tried to shut down all research, you find yourself battling and puzzle-solving across a myriad of landscapes to bridge the two worlds and get your friend back.

#956Even with Fable I'm still seeing wrong but plausible answers, which are the worst kind imo.
AGENTS.md didn't quite give me the right boost either, so here's my flow:
1. Asking 2 new sessions to review what I built in my other session along with guides/standards* 2. Having a third session judge the first two. It dedupes, and does a good job of only surfacing the important stuff 3. Ask it to make edits, etc.
Some missing parts that I've been finding improve review are: - current/past session context - indexed codebase - PRs/git history - research/guides/3rd party context*
I had been running this on my own for a long time, and just started to turn it into a product. It's free right now, would love any feedback (roast me). Looking forward to catching some bugs for you guys.
Thanks for reading!

#957On my local desktop the WebSockets can send messages at a speed of 3,250,000 per second. It’s just TypeScript and Node.js with very few dependencies. It comes with a perf tool.

#959An iOS app that tells you which of your credit cards to use at any store. The part that turned out interesting is getting your targeted bank offers (Amex Offers, Chase Offers etc) without a bank login: a Safari extension reads the offers page you're already signed into in your own browser session, and can tap all the little "add to card" buttons for you. Chase renders theirs inside shadow DOM in a virtualized grid so…

#960It's for those moments where you need to share something and you don't know which steaming service your friend uses. Or maybe for a group chat or social media post where people use different services.
It works with video games too!
