Oh gott das tut mir so leid! Hat sie in den 5 Jahren etwas LebensqualitΓ€t gewonnen, oder ist es gleich geblieben (oder gar schlechter?)

Echt so erschreckend. Hab letztens seinen Reddit post gelesen und war schockiert wie schlimm es sein kann

There's no SD cards on them, the is is on a flash disk soldered on the board. I just added my ssh keys so whatever is on them it's by the manufacturer

damn. would be interesting to track where it's sending all that traffic too. But now I'm too scared to plug the cluster back in πŸ˜…

2 days later I had some network troubles and I checked my firewall and noticed that something uploaded crazy amounts of data. It turned out to be the 7 LM3H nodes.

They uploaded 364 gigabytes (god knows where) and downloaded 12 TB. WHAT THE FUCK

@jeffgeerling.com did yours do that too?

Really weird. I bought my second #NanoCluster this time with 7x LM3H nodes. They come pre installed with an outdated version of Debian.

I did some basic tests, used the existing install to add my SSH keys. I had other things to do and left them running over night (still with the Debian install)

A 10 inch mini lab with a NanoCluster on top, some cheap switch with 10g SFP+, keystones, a sticker that says "Warning, critical infrastructure, please do not hack" in german, a Raspberry Pi  with another free slot next to it, a Thinkstation mini PC and an LED dot matrix panel

I've built a small Raspberry Pi cluster. Inspired by @jeffgeerling.com

but configured it in a way that I can controll everything that's running in the cluster from a single git repository.

Oracle war fΓΌr mich immer eine der schlechtesten Firmen. Wir mussten in der Ausbildung eine Oracle Zertifizierung im Bezug auf ihre Datenbanken machen. HΓ€lfte der Fragen waren eher Vertriebsfragen oder Fragen zu Oracles Produktkatalog. So unprofessionell war nicht mal Cisco

Trying out #Omarchy as my development OS. Gotta say the mouse free nagivation is pretty interesting. It's by the creator of Ruby on Rails.

An absolute catastrophy for Austria. It was a long time since our last school shooting and I hope that this was also the last for the decade

You should totally release a homelab version of the rack in a 10 inch mini lab. @jeffgeerling.com help me with this one πŸ˜‚

Matrix is a federated chat system that people can host themselves. Matrix itself doesn't have a GUI but projects like Element (element.io) fill that gap.

This is pretty close to discord but much slower in development because it's an open system
