#582More work on https://cardcast.gg. It's a way for my friends and I to play Magic: The Gathering online using a webcam. For those unfamiliar, you take the webcam sitting on the top of your monitor and point it down at your desk, then play with your friends using paper cards over a video call, but specifically tailored towards Magic + Commander.
Recently I've been focused on marketing and small bug fixes. I think the core feature set is compelling enough, now I want to draw more players and start building a community. Been doing some social media stuff, designing an icon (this is HARD for me, I'm not very creative), and looking to print out a bunch of Cardcast-branded Magic cards that I can hand out at my local TCGs.
If you play MTG, I'm looking for more people to come give me feedback and contribute. Feels like something others can benefit from!

#583Working on https://letterspractice.com
This is a high efficiency, narrowly-scoped, low screen-time early literacy app for families with kids aged 2+.

#584The final stretch of getting my game ready for release next week: https://store.steampowered.com/app/2764460/Sandustry/ It's an automation game and factory builder with "falling sand" physics. Think Noita meets Factorio.
really cool!

#585I love shared daily puzzle games. Wordle, crosswords, that kind of thing.
Swudoku is my take on a daily sudoku puzzle. All the numbers are on the board, you just need to rearrange them to complete the game.
Been running it for over a year now with daily plays from friends and family who enjoy it. Recently took a stab at an iPhone app for it as well.

#586Rated Analysis, rating relative chess analysis: https://rated-analysis.pickle-dev.com/
I've been a bit obsessed with chess lately and have read/heard things like "X is the top engine move, but no one under master plays that line". To me this begs the questions "which line are players below master playing" and "which line are players at/above/below my rating playing". This question motivated me to build a tool to analyze the move distribution (win/draw/loss rate) from a given position across rating buckets (400, 500, 600... 3000). Luckily, https://database.lichess.org/ provides an open/free database of games that have just the data required to build such a tool.
The Rated Analysis tool consists of an 1) an offline job to compute/store the positional move distribution bucketed by rating, and 2) the https://rated-analysis.pickle-dev.com/ webpage to serve the data along with some nice to haves like loading user games from platforms like chess.com/lichess.org.

#587I'm on paternity leave and I've been returning to a host of LLM driven projects;
They are all for me, with a small interest in commercializing some of them as a hustle.
Project: a local version of Claude Co-work for document organization, one of my original projects that I wanted from back in 2024, so it could help me find everything on my hard drive and turn it into a knowledge graph/mind map without sending everything over the cloud. Bonus for removing duplicates/disk cleanup.
Project: Memoria - an SMS based daily journal - my first platform! security, interoperability, yay! This started out as something for my wife to make notes on the kids milestones with an SMS reminder, but then I have ADHD type memory issues and wanted a voice based journaling system so that I could just narrate about my day and have an AI clean it up. At the end of the week it makes a little email with photos, etc for a week in review. Next step is a big lift if I want to format everything to be put into "baby books" because of the print publishing workflows.
Project: Curio - based on the platform above - helping to declutter based on capturing the sentiment of an object. My ADHD means that my memory is trigger based, and if you toss the thing, I lose the memory. I'm trying to find a way to get rid of things without losing my memory that comes from holding it in my hand.
Project: Deep Signal - an AI driven daily podcast that gathers AI papers and news based on my interests, then transforms that into a 15 minutes daily news segment. Started out on Google's platform, now just using Kotoro and Gemma 4.
Project: Book Explorer - like Sparknotes for non-fiction. Pushes everything into an ontology for non-fiction so that it can summarize it and make it very easy for me to "skim" books that I otherwise don't have time to read. Also helps me to deep dive into particular areas. This is probably one of my most frequently used tools.
Project: Meeting Notes - Before Granola existed, this was a local granola clone that used whisper. Only later did I find that the real gap in making this work seamlessly without the janky MIDI Audio Capture was that if it was a "signed" app it got access to much better resources.
Project: Hunch - a new type of trivia app that is based on bias and a "sense" of what is true. Made so we could play trivia across multiple education levels and generations with everyone still having fun. Still in development.
Project: Drucker MCP - using an MCP to inject prompts from a custom "library" so that I could steer a big model towards as multiple opinionated experts. Meant for business / entrepreneurs - I want to think like Peter Drucker, Alex Osteralder, Rogers, Scott Anthony. This one is the one that I hope can "make a dent in the universe" because I could make it freely available as an MCP and it can help micro-entrepreneurs in the Global South.
Project: personal finance app. keeping it local.
I suppose to get the triple crown, I need to make a work out app so I have "journaling", "fitness", and "personal finance." Or could be a to-do app. lol
Heck, most of these are still in development - but the Audio Capture was abandoned for freeware.

#588Sun signal. You can time your life events with the sun: think optimize work time, sleep time, rest time by following sunrise, solar noon and sunset.
It was my counter cultural bet to burn out and AI vibe coding all night long. Has worked pretty well.

#589Working on goldy: https://github.com/koubaa/goldy A new kind of GPU library written in rust with backends for CUDA, DX12, Vulkan, and Metal (tenstorrent and wgpu are planned) and bindings for rust-dynamic, python, c++, c, and dotnet (Java and Fortran are planned). Uses the slang shader language exclusively. All submissions are expressed as graphs (like cuda graphs), are retained automatically (sometimes partially wit…
But why? (not meant to be rude). why would I want to use this gpu library versus what is out there already? I don't understand the value of it.

#590I’ve been hacking on an outdoor sound monitor for 24x7 logging of birds and bats around my house the last couple of weeks with a live indoor monitor: https://github.com/simonjgreen/OpenObservatory And today I knocked out an improved trmnl plugin for Japanese flash cards at my wife’s request as she liked the native one from trmnl but it lacked furigana https://github.com/simonjgreen/trmnl-japanese-vocab Note: I let AI…
"When I asked the computer to identify it, what I got was European Warbler. You see, sir, the SAPS software was originally written to look for birds. And I think when it gets confused, it kind of runs home to mama."
