A FLAC encoder/decoder written in Guile scheme. I struggled to get the decoder working with most test files for a while until recently. It's more or less a fully functional decoder now. It's also 1:1 with the reference meta-flac command currently as well.

This week I’m publishing my open-source, email based commenting system for websites.

https://github.com/FarisZR/knocker

Knocker, an http knock based access service for your homelab that works at a reverse proxy or firewall level.

It's a more convenient albeit less secure alternative to VPNs like tailscale. It's more convenient because it whitelists the enite network, and it's less secure for that reason.

I'm adding an overly elaborate item and levelling up system to the adventure mode of my chess variant AI sandbox: www.chesscraft.ca

Items have a prefix and suffix system similar to Diablo 2 so I'm having nostalgic fun building it. None of this gives any advantage to the chess games you play. It's just a pointless cycle of gems, items, and experience to get more gems, items and experience. Seems fun so far.

8086 assembler in awk for retrocomputing purposes. Proof of concept worked well enough and now i'm doing an second version with more robust logic.

In the philosophy of selling shovels in a gold rush, I have built a Markdown Viewer for Mac which is optimised for AI coding with the likes of Claude.

It is simple but powerful supporting all formatting but also diagrams so you can get Claude to generate beautiful ER, or state-transition diagrams for your documentation. It also supports math notation, file links and has a cool table of contents feature

It's in the app store: ViewMD

Scratching my own (and my employer's, but they don't know that) itch and building a knowledge management system as a nerdy way of spending evenings. I refused to learn JS for years, but turns out it's not as bad as I thought, and TS makes it really nice, plus I like (to my surprise) SolidJS' JSX interpretation quite a lot. Half vibe-coded, half breaking things and learning a lot.

http://www.taxmax.dev - helps companies deduct more engineering spend.

https://github.com/s1liconcow/skyshelve - persistent python dictionary on S3. Used this to create a durable execution layer to do some of the analytics for the above.

Got tired of every single weather app and website being littered with ads. Half the time my weather apps don't load the weather maps but the ads work fine, c'mon! So decided to start my own; here's what I have so far...once I iron out the site I'll start on the Android app.

Feedback welcome :)

Looks good!

I have a couple minor suggestions, do with it what you want:

- I'd disable the fade between two visualizations on the live weather radar, it's hard to scroll through quickly now.

- Personally I'm always looking for the hourly and daily forecasts. Currently they are split by the live radar. I'd either move them all above or all below the radar if you want to keep this format
