Just trying to learn C again, making things from scratch in a multiplatform way, interfacing with X11 on Linux and wasm on the browser.

It's been fun dealing with memory and C's weird design in this age of agentic coding.

I was working on sharemygit.com

However, LLM coding has made coding less rewarding so… Im thinking about starting a new hobby as coding for fun has become prompting.

I’ve been building a shared memory layer across all AI tools

Realize that I'm really bad at marketing. Trying to work on it.

It lets you take a picture of video games and shows price comparisons for the major buy lists.

Used Claude to write conformance tests for https://aep.dev.

https://github.com/thegagne/aep-conformance-test

Did pretty well, only took a day or so. I first had it inventory every MUST, SHOULD, and MAY in the spec, and then let it rip. I did guide it quite a bit to get what I wanted, but at the end I’m pretty happy with it as a first draft.

Helped me learn the spec and will be helpful to hone my dotnet AEP server, and aepbase.

There already existed an aep e2e validator which does a similar thing, but this is more thorough and generates a nice report. It will tell you not just whether your API follows the spec, but also what parts of the spec it does not implement.

RV64 toy/hobby kernel. No compatibility aim but rather at efficiency and speed.
I am working on this Review Flow. An extention for Cursor / VScode to enable IDE as first class for code reviews.

It came from a frustration that I needed to switch between the browser and the IDE to navigate through the code and leaving comments on Gitlab at the company.

So I thought it could useful to create something and let it be accessible to the public as open source.

link: https://github.com/LuyandaLia/reviewflow

In a nutshell, it accepts draft comments, which can be modified and submitted.

It auto configs the env for Python as it uses FastAPI for calls to Gitlab.

It's my initial attempt. Suggestions, reviews, contributions are invited.

One love

This month I have mainly been building my fork of tiny-dfr so that my 2019 mbp touchbar isn’t useless when on hyprland/cosmic

https://github.com/keloran/tiny-dfr

Unfortunately due to the way GitHub defaults to creating prs in the parent fork, I have accidentally created a few invalid prs in asahi before I was ready, and now am banned from creating a good upstream one

Aggregator for new posts in build threads from 277 old-school DIY forums.

Build threads of people building cars, 4x4s, motorcycles, boats, airplanes, hot rods, musical instruments, etc.

Ohh this is the type of stuff that interests me although I am not a car fan but I like what you are doing with the aggregation/old-school DIY forums.

Good luck with your build and perhaps I might get interested in future too as I did once have a thought that having a custom car to me would reflect more cool-ness than an expensive one. I am really interested by small cars, perhaps retro. I imagine my favourite car to be somewhat like the car that Ryan gosling drives in La La Land.

but a cool project nonetheless, certainly thinking about it inspires a bit of car enthusiasm within me even though I am not that much of a car fan so much right now so a really cool project if it can help more people feel this spirit. good luck :-D

I have a question but how does building new (retro-inspired?) cars go about in terms of pricing. I feel like they might be too costly to get custom-built and that If I really ever in my life go about doing this, I would prefer DIY but I still imagine that it might be too expensive or hard to make a car. Are there any go-to cars which are easy/recommended within this space and how does it compare off economically and what are the technical expertise that you require with this type of stuff?

Once again, I wish ya good luck in the project and would love to hear your answers for some of the questions I have!

Thanks; much appreciated. I picked up an endless list of new build interests in starting the site and exploring different niche forums. Turns out I really like wooden boat builds, cyclekarts, intricate custom knives, handmade violins, the list goes on...

You're right that getting a car custom-built is where the costs add up quickly; easily north of $50K. Most of the cost is labor, which is $0 if you do it yourself. Some of the projects are much easier than others. If you want to fall down a rabbit hole, look in the kit car and hot rod categories; lots of affordable and small builds in there. The Buick Riviera in La La Land is more of a resto-mod cruiser project, but the small/retro itch is exactly what the kit car category scratches. The first step is to find a forum where people are building the car you like, and start following related build threads. That's the majority of my social media intake these days.

Thanks I appreciate your comment. I don't think that I might be that interested in car building right now but thanks for your pointers!

Speaking of which, I had made something at https://mirror.forum which revolved around forums and their ability to create communities on open source discord alternatives and it was always intended to revolve around forums/communities.

Feel free to check out my website for understanding what I might be talking about but I would be really interested in perhaps having the list of forums on my website so that people can search them through.

Do you have a list of forum websites that you used for your website or any resources pointing to that, I really like what you are doing and after thinking for sometime I think that it could be cool if I could use my application to point out to original OG forums as well. I would be curious to know what you think!

If you're interested in the day to day of where the hobby goes, I recommend a browse around /r/projectcar. It's a mix of first time builders, people thinking of getting started, and the old hands doing some absolutely amazing builds.
This is amazing! Very refreshing in the age of AI to see so much manual building going on. Sadly I don’t have much time myself but I have several friends who would love this, I’ll pass it on to them.
Thanks, that means a lot. I've found that browsing through a few dozen build threads is the perfect cure for the AI blues.
I've been climbing for a decade, but over the past 3 years I've put on a bunch of weight due to work and certain life events. But I want to change that.

I know what motivates me: seeing progress. The feedback loop of "do X, see Y gain" is what keeps me going.

So I started building an integrated dashboard that can aggregate data from multiple systems:

- My digital scale

- Apple Watch (sleep + running performance)

- Beastmaker Motherboard, which is an electronic board that you attach a hangboard to and it shows you various stats like how much force you're applying

The idea is that every morning I'll open the dashboard and be able to see exactly how much progress I've made the previous day: weight loss, strength gain, cardio performance.

It's an interesting problem. There's essentially two parts to it: Apple Health, which aggregates data from the scale and the Apple Watch and can POST-export it hourly, and the electronic board, which sends data via BLE in real time. The destination for both of these will probably be an always-on Raspberry Pi 5, but I haven't decided yet. Then I'll have a small server app that can pull the data from the Pi and draw some fancy charts.

I've been working on a similar concept (aggregate health data from multiple sources) but on a wider scale: 1) annual bloodwork as part of my annual preventive care; 2) InBody measurements, including grip strength; 3) quality of air in my region; 4) Apple Watch but mainly for steps, sleep data and resting heart rate; 5) allergy panel or minerals/vitamins screen plus something nutrition-related along those lines (TBD).

The idea is to see trends and try to apply AI for correlating, at the first glance, completely unrelated data layers. Example how I'm thinking about this one: there's somewhat clear correlation that I sleep better when I do above average steps per day. How is my sleep quality affected if, let's say, I did above avg steps with a bad air quality at that time? (i.e. wild fires / pollen season / etc.)

I've built a Go application to ingest those data sources and currently finishing my first import use case - Apple Watch data.

Would be happy to connect and chat about this.

I'm a physician, and I'm extracting data from Apple Health and using what exists with solid and sound evidence to analyze sleep. Personal project it would be great to connect with both of you.
I am building Bloomberry (https://bloomberry.com), an alternative to tools like BuiltWith/Wappalyzer to provide sales signals when companies subscribe or churn from over 1600 B2B tech products. Think backend/backoffice tools like Hubspot CRM, or Netsuite, or Microsoft 365, rather than frontend technologies like Wordpress or React.
I'm working on a multiplayer RPG https://grimrain.com - calling it an MMO is quite bold, but the gameplay fits that genre. The game server is designed to be self-hostable too, so it's like Valheim meets OSRS
Looks great! As a tenured Runescape player, I like the graphics.
