Last December, I started building a desktop app so that I could keep all my running, eating and assorted physical misadventures in one place. I decided to build it with Electron so started profiling right away but wasn’t write home about it happy with any profilers so now I’m building a profiling tool and the fitness thingamajigger in tandem. And of course, it’s a personal project so scope creep is an issue. Now I have structured logs, full replay and so much data that this wacky little profiler makes me feel bad about all the decisions I made on the wacky fitness app six months ago.

Which just goes to prove, if you’re slightly demoralized it’s a side project. :)

On my free time I've been making a small "game" where you control a spacecraft using a 6502 computer. You can control things like thrusters, antennas and read data from star sensors, gyros, etc. using memory mapped I/O directly and you can't control anything directly.

The whole thing works pretty well, it's built using Godot & a custom Rust extension with the 6502 emulator & assembler. It can even be exported to the web so you can write your code using a CodeMirror editor and send it to the game in the browser.

Now, as expected, the hard part is making it fun. Just giving players an empty code editor and a manual for the sensors/actuators doesn't seem great, and there's also no goal for now. I'd like to take inspiration from Shenzhen I/O to build a sense of progression by tackling more and more difficult control challenges maybe?

It also supports running multiple computers at once so I think there's some fun potential for a "multiplayer" mode where you try to achieve some objective (scanning X, mining Y) against other players by sending spacecrafts with your code on them and all the crafts would run on one server. Anyway I'm curious if people would be interested in such a game!

I've published a lot of interactive programming courses on Boot.dev over the last few years, but the issue that's been plaguing the platform is how quickly it moves through material.

Like we give people challenges for each new concept, but we don't give them 4 or 5 challenges for each new concept. It's hard to get right because

1. It's a lot of work to make challenges/review material 2. Every student wants a different amount of practice/review

So anyways I think we've got a really good solution in the works, been cooking on it this week and we're hoping to be ready to go live in August

Nest Thermostats of the 1st and 2nd generation will no longer be supported by Google starting in October. I'm working on an enclosure-compatible open-source version of the 2nd gen Nest thermostat. It reuses the enclosure, encoder ring, display, and mounts of the Nest but replaces the "thinking" part with an open-source PCB that can interact with Home Assistant

Upvoted. Anything that creates off ramps from the surveillance for advertising industry is great! Even tiny ones.

A new YouTube app/player, for my kids. It allows us to control the algorithm. It’s all LLM translating to YouTube search queries under the hood. Visually it looks the same. The suggested videos come from predefined buckets on topics they love. E.g. 33% fun math, 33% DIY engineering, 33% creative activities. Video recommendations that have a banned word in the title/desc don't get displayed e.g. MrBeast, anything with…

Nice idea. Do you have a timer .. like after a half hour of playing it recommends them to go outside and play (after checking with parents)?
