Interestingly, not a video about police brutality, but about known unsafe roads.

The joke is electricity and Linux.

The real answer is the free hardware.

My main reliable is from 2008? It cannot do modern virtualization due to not having the CPU instruction sets.

Yes, but Microsoft named it.

Apt-cacher-ng doesn’t tend to expire automatically. It can be configured to keep the last version regardless. https://www.unix-ag.uni-kl.de/~bloch/acng/html/maint.html#extrakeep

One can also use a cache to hold deb and rpm files requested by the machines. (Works great when running hundreds of systems.)

I like “apt-cacher-ng”. It will do deb and rpm. https://wiki.debian.org/AptCacherNg

Offline repository caches for Linux have been a thing for decades. People absolutely pass binaries to friends.

Flatpac may not be suitable, but that is only one way to get software on Linux.

Pretty much every Windows machine I’ve ever owned after a certain year requires you to type in your Bitlocker key, including my first-gen Surface Go from 2018.

This is interesting. I had a work computer require this ~4 years ago, but not one of the three since have (personal and different employers.)

My first system was hacked so fast. Thank you RedHat for defaulting all services on.

I hate modern AI, but that is what we need it for. Maintaining old code bases, and not turning it into a text editor/AI API (unless that was the original intention).

Edit: I have to add more words. Maintaining code bases includes compling and testing the code on a variety of hardware. Running tests against that code. Responding to questions. It is a massive amount of work.

Yes.

Other options are LUKS with Tang and Clevis, or LUKS with SSH and Dropbear.

Sorry, I have no details.

Edit: Tang/Clevis are local software and a network server that provide keys. If stolen, won’t boot.

SSH and Dropbear make it so you can login to provide keys.

It is complicated. There are several options, each with tradeoffs in functionality, compatible software, and performance.

A simple method is to use one system as a desktop, and SSH into the others as “headless”.

Other options include making a K8s or HPC cluster (there are other cluster types).

Spreading a single set of communicating processes requires a low latency interconnect. Something better than Ethernet, like Infiniband. But many programs don’t support that.

What features do you want?

What should my first configurations and preparations

Write on paper your goals. Write on paper a list of your systems and what needs to speak with what.

Then pick the most important or simplest device and get it connected the way you want.

At home, colors Whatever color the purpose is.

For the out of the loop, but also lazy;

Android app that reveals installed apps which may be leaking your location data.

You put lots of time and effort in. Now it will be discarded due to decisions of others.

Sad and/or disappointed feelings are normal.

Take care of yourself.

Look up what system vendors will sell for that CPU. If they sell 256 GiB, then you are likely good.

I don’t find I ever upgrade after the first couple months. I would max it out or get multi CPU boards wherI cannot afford to max it out.

Good on you learning new skills.

This is why other sysadmins and cybetsecurity exist. Be nice to them.

Phrasing.

A Linux maintainer wants to keep quality high. Objects to adding complexity to codebase.

Right or wrong, we want the maintainers focused on quality and maintainability.
