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.
#sysAdmin
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?

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. 🔧🚫

Didn't I update all of $These Saturday morning? Why yes, yes I did, dammit.
I have a #SysAdmin question: is it okay to use a local, loopback-only SMTP server (#mailutils + #postfix) 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 (#ApacheAnswer), even though it does have an unauthenticated mode for SMTP. What am I missing?
SNMP (Simple Network Management Protocol) and NetFlow are two key technologies used for monitoring devices and network traffic across IT infrastructure

☀️ 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.

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?
