The problem with renewables is the fluctuation. So you need something you can quickly spin up or down to compensate. Now you can do that with nuclear reactors to some extent - but they barely break even at current energy prices, and they keep having the same high cost while idle.

So a combination of grid storage and power plants with low cost when idle (like water) is the way to go now.

I was referring to work setups with the overengineering - if I had a cent for every time I had to argue with somebody at work to not make things more complex than we actually need I’d have retired a long time ago.

Unless you are gunning for a job in infrastructure you don’t need to go into kubernetes or terraform or anything like that,

Even then knowing when not to use k8s or similar things is often more valuable than having deep knowledge of those - a lot of stuff where I see k8s or similar stuff used doesn’t have the uptime requirements to warrant the complexity. If I have something that just should be up during working hours, and have reliable monitoring plus the ability to re-deploy it via ansible within 10 minutes if it goes poof maybe putting a few additional layers that can blow up in between isn’t the best idea.

Everything is deployed via ansible - including nameservices. So I already have the description of my infra in ansible, and rest is just a matter of writing scripts to pull it in a more readable form, and maybe add a few comment labels that also get extracted for easily forgettable admin URLs.

Netzteil + Backplane mit Managementinterface und Hotswaprahmen - wenn ich das richtige gefunden habe hat das vor dir genannte Gehauese nichtmal Hotswaprahmen.

Ich hab vor ~zwei Jahren verschiedene solche Gehaeuse zum testen gekauft, in der von dir genannten Preisklasse das SC-4004 von Intertech (Hotswaprahmen, keine Backplane/Netzteil), und als teuerstes Modell das SuperMicro. Handling/Verarbeitung sind meiner Meinung nach den Aufpreis komplett wert - das SC-4004 steht seit laengerem vor allem wegen der schlechteren Verarbeitung ungenutzt rum.

Supermicro SuperChassis 721TQ. Kommt mit Hotswaprahmen fuer 4 Platten und 350W-Netzteil. Sehr solides Gehaeuse, fuer Supermicro-Boards vorbereited (Backplane hat Ueberwachungsanschluss), nimmt aber jedes MiniITX-Board (ggf. halt die Ueberwachung nicht anschliessen).

Das wirst du ausprobieren muessen - ich habs bei Freunden fuer mich vor Jahren ausprobiert, ich komm damit nicht klar und bevorzuge klassische Tastaturen.

I nowadays manage my private stuff with the ansible scripts I develop for work - so mostly my own stuff is a development environment for work, and therefore doesn’t need to be done on private time.

A lot of the Zen based APUs don’t support ECC. The next thing is if it supports registered or unregistered modules - everything up to threadripper is unregistered (though I think some of the pro parts are registered), Epycs are registered.

That makes a huge difference in how much RAM you can add, and how much you pay for it.

It has been a while since I touched ssmtp, so take what I’m saying with a grain of salt.

Problem with ssmtp and related when I was testing it was its behaviour in error conditions - due to a lack of any kind of spool it doesn’t fail very gracefully, and if the sending software doesn’t expect it and implement a spool itself (which it typically doesn’t have a reason to, as pretty much the only situation where something like sendmail would fail is a situation where it also wouldn’t be able to write a spool) this can very easily lead to loss of mails.

I already had a working SMTP client capable of fishing mails out of a Maildir at that point, so I ended up just doing a simple sendmail program throwing whatever it receives into a Maildir, and a cronjob to send this forward. This might be the most minimalistic setup for reliably sending out mail (and I’m using it an all my computers behind Emacs to do so) - but it is badly documented, so if you don’t care about reliability postfix might be a better choice, or if you don’t just go with ssmtp or similar. Or if you do want to dig into that message me, and I’ll help making things more user friendly.

Because it does JBOD if the controller supports it. Pretty much none of the controllers you’ll find in consumer hardware support that.

JBOD relies on an optional SATA extension, which most of your controllers won’t have.

That leaves you with RAID in the controller - which is a bad idea, as you don’t have much control over what is going on, and recovery if it fails will possibly messy.

Eventuell I-USB7? Proprietaerer Stecker, unterschiedlicher Pinout je nach Hersteller.

Ich hab das hauptsaechlich bei digitalen services. Ich schreib denen dann immer das ich ab jetzt deren Kram via Torrent beziehe weil sie entweder ihre Infrastruktur nicht im Griff haben, oder Datenverkaufende Arschloecher sind.

Bekommen Kunden eigene Builds, oder generische Builds, nur ggf. mit separaten Konfigurationsdateien/Anleitungen pro Kunde?

Beides liesse sich ueber das CI-System erschlagen, nur an jeweils anderen Stellen - bei ersterem Branches in den jeweiligen Software-Repos, bei letzterem eben ein eigenes Repo das die Dokumentation und Metadaten hat um die Buildartifakts aus dem Buildsystem zu holen. Ich wuerde das so loesen dass bei einem Doku/Metadatenupdate in dem Repo CI dann einen Archiv mit dem ganzen Zeug erstellt das dann direkt an den Kunden geht.

Das setzt jetzt allerdings voraus dass ich halbwegs ordentliche Buildablaeufe habt - was leider weiterhin nicht selbstverstaendlich ist. Falls es daran hakt wuerde ich erstmal schauen da was aufzubauen.

(Disclaimer: Ich hab eine Firma die als Hauptfeld Beratung und Implementation von CI, Testautomatisierung, Changemanagement und damit verwandte Felder macht)

You still might want to do something like alias pbtar='tar --use-compress-prog=pbzip2 to easily use pbzip2 - unless you have an ancient system that’ll speed things up significantly. And even if you don’t it’d be nice to use it for creation - to utilize more than one core the archive needs to be created for parallel extraction.
