#442I have been slowly progressing on writing a Rust like language that compiles to JavaScript for a few years now. With the rise of AI and it becoming better recently with Opus 4.5, specially with Rust, I've been trying to have a speedrun version of it.
Think of it as TypeScript but with full algebraic types and other commodities from Rust:

#443Working on Bold (https://boldvideo.com)
Video intelligence platform for coaching programs and training companies. The problem: these businesses sit on 200-500+ hours of video content that becomes a "content graveyard" - students can't find what they need, coaches burn out answering the same questions, churn stays high.
We do deep transcript + metadata extraction, then layer RAG search and an AI assistant that can answer questions with timestamped citations back to the exact video moment. Think "ChatGPT for your video library" but with accurate sources instead of hallucinations. Tech: Phoenix/Elixir backend, Next.js portals, two-tier RAG architecture.
Currently serving a few coaching programs in high-touch sales mode. Would love feedback from anyone who's built RAG systems over media content - curious how others handle the signal extraction problem (transcripts are noisy, you need to identify what's actually being taught vs filler).

#444I shared this last month, but I’m still having a lot of fun working on it. I made a daily word puzzle called Tiled Words. https://tiledwords.com Currently about 2,000 people play every day and I’ve released 59 puzzles! One feature I’m excited about is crowdsourcing puzzles. Today’s puzzle is a “community puzzle” made entirely from clues that players submitted! I plan to do this every week or two. I wrote about launch…
This is such a fun game. Thank you.

#445I’m kicking off my 2026 book club! It’s probably a bit different from book clubs you’re familiar with.
Each of us is reading sixty books over 2026, five a month, where every book is self selected by each member.
It’s small, six people, all brought in by application only.
You can check out our shared bookshelf here! (Heavy inspiration from Stripe Press)

#446I’m trying to build 1 decent iOS mobile app per month.
Most recently released one was My Vocab Quest[1], a vocab mastery app with lots of word packs. It uses some gamification mechanics to make sure the user puts in the reps.
Current apps in the hopper are centered around:
(1) Recovery from cosmetic surgery. There are several balls to juggle for days, weeks, and months after a surgery. The app helps the user follow surgeon instructions, promoting physical and mental recovery, as well as medical and dietary changes. Makes use of phone features including contacts, calendar events, notifications. I’m learning to build an App Clip for it and hope to partner with some surgeons to get it promoted in their offices.
(2) Assisting older Americans to be more independent for a little longer (a parent of mine has early stage dementia). Helping the user maintain a regular schedule, take their medications on time.
(3) A dating ideas / meal ideas and agreement app. It helps increase creativity for date ideas, learns from how predictable you are, and facilitates agreement between the users.

#447Continuing to add new features for my traefik plugin that manages bot traffic: https://github.com/holysoles/bot-wrangler-traefik-plugin
Also working on getting Nix setup on my devices, including a PR for the official installer to support OpenRC + BusyBox distros. Hopefully will get merged soon :)

#448Deciduous.
It's a way of working/tools for working with an LLM that allow you to track decision tree graphs, have the robot make more informed decisions and build its own logical chain for history keeping, and modeling all the work as a DAG of events, goals, outcomes, decisions, and observations that network together to allow you to work better/smarter/faster, giving it a living and recorded memory and ways to explore all this.
It's easiest to check out the short demo on the site.
It also links to the live graph of how the tool has built itself.
