…I use as a Micro Python sandbox. I've been using UDP to send CPU stats for my machines for ages ( https://github.com/rcarmo/raspi-cluster/blob/master/tools/se... is a good example), and in modern networks it has become very much reliable…

I think this is a sort of rite of passage. I just realized that https://github.com/rcarmo/raspi-cluster is TEN YEARS OLD now…

…that will send UDP packets with stats at regular intervals. I’ve done that a number of times - https://github.com/rcarmo/raspi-cluster/blob/master/tools/se...

…for the other Pis - this makes it easier to do a lot of stuff, including auto-configuration. * https://github.com/rcarmo/raspi-cluster

This is neat. I've been doing the same with Pi 1s and 2s for a few years ( http://github.com/rcarmo/raspi-cluster ) but stopped short of upgrading to 3s and 4s because of heat/power/cost. I've found that it is possible to run k3s on SD…

…servos, used them as cameras, the works. Right now I have: - A 5-node Pi 2 cluster running k3s.io ( https://github.com/rcarmo/raspi-cluster ), and a separate Pi 2 I use as a Docker build box and local Docker registry. - A Pi 4 as a "lab"…

Yep. Only yesterday I updated the scripts for my Pi 2 cluster ( https://github.com/rcarmo/raspi-cluster ), and getting https://k3s.io running on a cluster of Pi4s seems like a good way to upgrade that.

…Series Bs... which are essentially obsolete by now. I stopped using them around 2 years ago: https://github.com/rcarmo/raspi-cluster Using Pi 3 boards would quadruple the number of cores and yield a 600% increase in thanks to the slightly…

Neat. Anyone else at HN did something like this? Mine is at https://github.com/rcarmo/raspi-cluster (configs and some utilities included)

…it would most likely work: On the other hand, you can easily code your own without too much hassle. https://github.com/rcarmo/raspi-cluster includes a minimalist Dashing clone with a Go backend and real-time updates.

I'm thinking of upgrading my Pi cluster ( http://github.com/rcarmo/raspi-cluster ) to a set of these boards. Mostly waiting for some benchmarks to come in and the holiday season to go away...

…released their internal Android build. Edit: forgot to mention I have five Model Bs in a cluster ( http://github.com/rcarmo/raspi-cluster ) where I run distcc and toy with Java/Clojure/Hazelcast. It's fun, but requires a fair bit of…
