Oh man I really want one of these #bagnole

Ok writing some #eBPF which hooks onto a #cgroup and limits its network access while leaving the rest of the host unaffected, this is fun! Bit of #c and #golang

@TALlama a common one I see is adding a log line to the end of a method without realising the previous lines output was relied on, other cases are where if/else/rescue where it’s no immediate obvious which line of a method is the “last”. Some of this is helped by #sorbet as it’ll flag if you are returning the wrong type

It's not a real change freeze unless it's enforce by the #vogons

Folks that are using #butane for with #fedoracoreos or #flatcar how do you handle secrets in the configuration?
I'm looking at the idea of removing the config after initial boot or some other option.
One route would be to use single use secerts (which work for say #tailscale which supports them) but not for others

In search of a “Zero Toil” HomeLab: Immutable Linux, ZFS, WatchTower and Keel
👆 Blogged about my #HomeLab #fcos #immutableLinux #zfs

Posted an answer on #stackoverflow for the first time in ages.
It's how to specify per-container more permissive #SELinux permissions when running in #fcos

Playing with #Piccolo (#Python #ORM) and really enjoying it.
The `piccolo asgi new` command to boostrap a new webapi project is really handy as someone who's not been in python ecosystem for a while.
Migrations handling is also pretty neat
Thanks to @martinpeck for recommendation.

Ok in 5mins with @tailscale I'm able to expose out services from my #kubernetes cluster to my tailnet with nice DNS names and all. All entirely private to my #tailnet
This is soooo nice 🙇

Today I ran a script which did “sudo rm -rf $variable/*”
Problem was, due to a bug, $variable was empty string.
Never been so happy to be in a #codespace - berated myself for 3mins while waiting for me new one then carried on working.

Too much “magic” and auto configuring cleverness in software causes so much pain on daily basis.

Here is it next to the #moonlander and #gameball for scale

Brought a new #trackball mouse and love it.
#gameball (not using it for gaming)
Nice’s left handed trackball I’ve ever used !

I want to make an automation which, when #solar battery is full, the doctor from #teamfortress shouts "I am fully charged" from our speakers.

I'm playing around with the idea of adjusting my homelab's behaviour based on the #solar output from my roof array.
The rough idea is to alter the CPU governor settings and schedule intensive work based on live generation stats by messing with #kubernetes cronjobs, think "ecocronjob"... "do between x and y time when we have most spare energy"
My #givenergy system I've got has a #modbus interface I'm hoping to hook up too. https://github.com/dewet22/givenergy-modbus
