I was curious if I can use new Lambda MicroVMs as self-hosted GitHub Runners. On paper, they are super nice:

It's cheaper: GHA-hosted is $0.005 / min (2 vCPU), MicroVMs ~$0.0042 / min, and no minimum 60-second commitment as with GHA-hosted.

It can run longer: GHA-hosted max 6 hours, MicroVMs max 8 hours

It starts in a few seconds, compared to whichever other serverless solution built on top of ECS

It scales to 0, or rather, it only runs when jobs are running

They are VMs, so you can still run containers/docker/whatever else inside;

I got a bit too invested, and ended up building this Terraform module. You only need to create GitHub App manually, the rest is just a single "terraform apply" and your MicroVM Runners are ready to go. I've switched come of projects at my company to use, works great, same or better performance as GHA-provided runners. Natural limitation is that MicroVMs are only arm64, and in general they don't have much flexibility around the "hardware" setup - but hey, for most cases, it should work great, and it's just 1 webhook + GHA JIT Runners + 1 MicroVM Run per Job.

Amazing what one can vibe-code these days. I am not an iOS dev, but I am pretty technical, focused mostly in cloud infrastructure and architecture. I like playing video games, and this new Forza Horizon 6 is fantastic. While going through the menus, I saw that it can send telemetry data to any IP over UDP, so I was curious how far I can get with creating an app that would serve as a server and visualize this data. Hours of having fun tweaking it (good thing is that to test this app, I need to play Forza), and 3 weeks of waiting for Apple approval, the app is out and is free to use with no ads. Hardest part was to build a race log, detection whether that car is on a particular race/track in the game, and attributing race attempst to these tracks - but I managed to do it!

I've shared how we at mkdev.me auto-generated alt image descriptions for all of our existing (1000+) and new images.
