I'm making a TypeScript type checker in Rust.

tsz is my main side project. Trying to learn from this for how to make software in fully automated fashion. tsz's goal is to match tsc (tsgo) but perform better. I am not passing all tsc's own test cases and working towards making it work on complex type packages.

Building a gameboy speaker from scratch. Kind of like a record player or mini disc player, but using gameboy and gameboy color games. Trying my best to document the process https://www.youtube.com/shorts/MQ16pvz3xeQ

Lots of fun and novel problems to solve across hardware, software, firmware, enclosure, legality, manufacturability! It also got me collecting random carts just to hear the incredible music locked away (some samples at the end of this video https://www.youtube.com/shorts/7naKAga8hAE )

Currently I am working on a browser + server based video editing site. The site is almost 6 years old and started as something I made for friends on Discord. It's a tool based site where I add tools as friends and family request them, most tools like resizing a video, cutting a video, extracting audio use ffmpeg wasm and run in the browser but I also have the option to process it on my server which is faster. In the last couple of months I have started experimenting with AI and I have added some AI tools such as transcription, image generation with small models and stuff like that. I am also dogfooding the website for my $dayjob so I added a browser based screen recorder which allows me to create short tutorial like videos and quickly share them with clients. https://editclips.online/

I’ve been playing D&D for a few years with friends, and over time we’ve built a rich world..full of contradictions because I can’t remember half of the improv I do as DM.

I built https://loracle.app to automatically build a wiki of various entities in our campaign and enable rag q&a with an ai assistant about specific world facts.

Arcane Scholar: a local first application for all your TTRPG needs. Create and manage characters, classes, spells, and more. Then package them up to share with your table.

In the style of Sauron I’m channeling all my frustration and hatred of slow loading tools that require you to pay a subscription, buy the digital book on every platform you want to use it on, and won’t let you use the physical book from your shelf.

For my first pass I decided on focusing on a character creator for a single game and streamlining the process.

I started with the 5.5e SRD but got frustrated with the sheer amount of text without much actual content ( 100+ A4 double column pages of spells, only 1 subclass per class ). Plus a number of weird and frustrating rules that make it hard to create software for. As I’m using Nimble RPG at the table a bit recently and it has a much nicer license I’ve switched to that and been getting on a lot better. Character creation is almost done and I’be moved to character sheets and persistent object storage now. This is the first major project I’ve done with sveltekit and I’m really enjoying it.

Fork of Bitwarden's Chrome and Firefox extensions (password manager) with UX improvements to make the tool useable.

The coolest feature I added was a tool to handle passwords under duress.

I'm still working on the Chrome version, but this is the Firefox version:

I'm working on rookery, "A PGP-first, self-hostable email server that comes with a web mail client and modern standards out-of-the-box.": https://github.com/oleblaesing/rookery

If you are a privacy minded person like me, you got only a few options when it comes to email with some ease of use: ProtonMail, Tuta etc. Rather than becoming a new competitor to those, I want to give the power of the decentralized email standard back into the users hand. Everyone with a bit of self-hosting/Linux knowledge, can setup their instances for themselves and their friends/family/business.

Bootstrapped that heavy via vibe coding. Used it to learn a lot about the email standard and related technology. However, I find it too valuable to just be a learning project. Now I'm cleaning it up to get in control again and to proof its secureness by rewriting/restructuring/refactoring line by line.

Protonmail (and I guess all others including Gmail, except Fastmail) has a nasty feature, where the sender can put an expiration date on emails and practically get a confirmation you received the email without you ever knowing you received the email.

If the expiration is for example one day, you might never see it.

To my knowledge, Protonmail does not even show information that the email has expiration. Nor can you access log of deletions.

This feature was used against me on a court trial.

I am working on an email spam filter - would it be interesting to you? An extension perhaps?

Sounds great, share it if you want - using rspamd right now, don't think it's worth the switch at the moment though, as I just want to stabilize/deslopify everything first, before iterating on individual aspects.

I just wrapped up https://llmrender.com/, a tiny (10kb) Markdown to React renderer works with all of the Markdown + LaTeX math you'd normally expect in a normal project.

I made it because doing one of the mainstream Markdown renderers + Katex (LaTeX) + Prism.js (syntax highlight) adds 300kb of gzipped JS to the frontend projects, so with this you can have it all for just 10kb. It also works well with streaming/does stable partial rendering.

It supports features usually reserved for LLM chatbots, but also for normal everyday Markdown, so feel free to use it or give feedback!

I’m working on https://getvedahome.com

My mother had a stroke a little over a month ago and I don’t live close by. I went in search of a wellness product that would let me know how she’s doing without her feeling I’m prying too much. I didn’t find one, so now I’m trying to build it. I’m also working on moving closer.

Have you looked at Home Assistant (HA) as your consolidating platform? I helped set up one in a nursery home with mmWave motion, temp, humidity, switches, electricity flow, etc. If they want to, they can control water faucets, sinks, flushing WC, ceiling fans, heat/cool, plugs and switches.

The beauty is that you just need to find a device with either existing comms "protocol" (e.g., RESTful APIs, MQTT, Zigbee, Z-Wave, BT, BLE, Metter, Wi-Fi) that HA understands, or get one of the many community solutions for others (e.g., LoRaWA, 433MHz, modbus).

No, I hadn’t. I appreciate the link! My mom is completely non technical (can barely use an iPad), but this could be a great thing to build on.

https://www.home-assistant.io/

the interface can be set up on her phone, a tablet on a wall, and limiting things to giant buttons and displays is very easy for you.

And, you can monitor and be alerted near real time to issues of course.

Fantastic! I hope you just solved my issues!

I'm working on my vehicle building game https://mechacraft.io that I recently released on CrazyGames (my first released game!). It currently sits around 60 CCU which isn't great so I'm polishing/reworking things to see if I can increase it in the next few months. I'm also still looking for a rev share partner that can handle the visual side of things something along the lines of a technical / 3D artist.
