So the external monitor is finally flaking out it seems. I've been shopping around and I REALLY don't want to pay the Apple "Tax", but, man, the Studio Display seems to be the only monitor I can find that fits all my criteria. Been eyeballing it for awhile, seems inevitable at this stage.

I have a question to the #SysAdmin #IT #Linux people. My first attempt to get answers here.. Let's see.

I plan to migrate an old #Wordpress
site.

Here one step:

"Ensure the old database is compatible with the new version, and adjust any necessary settings."

Are there any more details? Is there a repository of migration scripts for databases when upgrading between Wordpress versions?

This is a pet project, I am not a Wordpress guru.

You need extremely simple monitoring on Linux?

Systemd files ->

importantthing.timer:
Some timer Stuff
importantthing.service:
[Unit]
OnFailure=failed-unit-warner@%n.service
[Service]
....

failed-unit-warner@.service:
...

Type=oneshot
ExecStart=curl -fsSL -d "Hostname: Systemd Unit %i has failed" https://some.ntfy.pubsub.server.example/topickey

New Linux flaws let attackers gain root on major distros incl. Ubuntu, Debian, Fedora & openSUSE. 🐧🔐

Two LPE bugs—PAM config & udisks via libblockdev—can be chained for full system takeover. 🧷⚠️

udisks runs by default on most systems, making this a critical risk.
Admins urged to patch ASAP. 🔧🚫

I have a question: is it okay to use a local, loopback-only SMTP server ( + ) to allow a local web app to send mails directly? Without any login/passwd?

This works fine:
echo [boty] | mail -s [subject] [dest]

But I can’t make it work from my app (), even though it does have an unauthenticated mode for SMTP. What am I missing?

Scripturile Bash sunt ca niște mici asistenți care te ajută să automatizezi sarcinile obișnuite, să reduci erorile umane și să economisești timp prețios. […]

☀️ Buenos días!

Mientras aún estamos en pijama, los servidores ya llevan horas currando:
- DNS1 va sobrado con un 76% de aciertos
- DNS2 está más relajado (es domingo, que se note)

Sin cookies ni historias raras, solo DNS que funciona.

FUCK YOUR #DOCKER! GIMMIE AN #RPM OR THE GODDAMNED #SOURCE
#SysAdmin

I have a feeling that there is a need for a structure that maintains helm charts for popular open source apps.

Pros:

- doesn't depend on a single maintainer
- can easily onboard more maintainers
- can have a consistent set of guidelines on how to write/use the charts
- can be paid by upstream to take this responsibility

Cons:

- can work against upstream's commercial interests
- requires governance / operations overhead
- competes with Bitnami?
