Linux

I learned to never settle. If you don't like the default workflow of Gnome, try some extensions, or even a different DE. Same with Package Managers. If you don't like the syntax, make an alias. Don't just "deal with it". Windows has brainwashed people into thinking that there is only one way to do a thing.

How to quit vim.

That I could put /home on a different drive
That I would never boot into Windows again so having partitions for it was a waste of time
That mounting drives with their uuid as the mount location is insane

The 1:1 windows:Linux replacement is just a means to keep you on Windows. Once you learn Linux, you'll come to understand how much of a farce it is and how it's designed to keep you away

It was free, I could not afford a Sun workstation and Minix had problems, so when this Finnish guy wrote in Usenet that he was working on a free kernel/OS, it was cool!

Linux is pretty easy to use nowadays. The only thing I would check before switching is driver compatibility.

I wish I'd known how much of a pain in the ass having an NVIDIA card would be. I would have gotten a different computer.

Distrobox exists, so one is not bound to use a specific distro just because it packages some of the apps/binaries they require.

"20 years from now, people are still discussing moving to Linux!"

• tab completion in bash
• vim
• zfs
• git (though it didn't exist then)

It was ~20 years ago so my advice to myself then would be pretty irrelevant now. I messed up my laptop, and my advice then would have been don't start with a laptop (because laptop compatibility was lacking back then compared to desktop, different times).

When you're just trying to get work done: pick a solid, well-tested high-profile distribution like Fedora, Pop!_OS, or Debian (or Ubuntu). Don't look for the most beautiful, or most up-to-date, or most light-weight (e.g. low CPU usage, RAM, etc.). Don't distro hop just to see what you're missing.

Of course, do those things if you want to mess around, have fun, or learn! But not when you're trying to get work done.

Rasberry Pi or other NUC is a great way to begin.

Don't get an Nvidia gpu

That even though you are running an LTS version of Ubuntu (e.g. Ubuntu 22.04), some packages that have arrived over a year ago on e.g. 23.10 will never arrive on 22.04.

Example: i3-wm 4.22 or up (https://packages.ubuntu.com/search?keywords=i3&searchon=names&suite=jammy§ion=all).

That I shouldn't care as much about installed packages I no longer use. Sure, going through installed programs and cleaning up from time to time is ok, but no need to panic if something sticks around.

Especially when I installed something manually needing dependencies for programming, I tend to write down names of installed packages and then managing it manually, because I wasn't yet aware what their names mean. Now using same OS for over a year, heavly testing stuff, having multiple desktop enviroments and not cleaning it up my system partition is taking less than 30GB, compared to 1TB disk it's nothing.

Always put your filesystems in an LVM volume (and in general, partition disks with LVM rather than partition tables)! You never know when you might need to combine multiple disks, make a snapshot, add redundancy, or transfer to another disk without unmounting. But it's very difficult to format a block device as LVM once you can't erase its contents.

Make your /boot partition at least 500MiB.

Leave at least 1GiB of free space at the beginning of every disk. You never know when you might need to add EFI and boot partitions to that disk. And again, it's very difficult to do after the fact.

Unmounting removable drives after writing to then is crucially more important than on Windows

TIL there's tab completion lol

Nothing, to be honest. It just worked and I loved it.

Gnome is better on 1920 than in 1366. XFCE is better on 1366...

And Ubuntu sucks..

After switching to Linux I wish I knew how to report bugs. I'm a qa tester and I notice so many little things that can be replicated and fixing them would polish the user experience. But there are so many layers I don't know who to report the issue to. My first thought wasto report it to the distro forum and have the more technical people there take a look at the issue then escalate it to the distro maintainers or the actual software devs.

Another thing I wish I knew, was how to get my 2nd hdd to mount automatically. I fucked to my system 4 times(and recovered it) trying and then had to get my sys admin friend to do it for me.

Though I enjoy and am currently using #LinuxMint, I wish I learned about #Wayland sooner. I didn't understand why game performance felt so off with my dual monitor setup for several months. I have since dabbled with an #Ubuntu #Gnome DE for some gaming, and Wayland support has alleviated those problems. However, I plan to look into other options when I've organized my data a bit more and establish proper backups. Learning #Bash, #scripting, #aliases, #workspaces and tweaking #hotkeys were also useful for making my workflow into what it is. Also, I wish I knew how bad #ProtonVPN and #ProtonDrive #Linux support would be. Despite getting used to their #CLI applications, the absence of feature parity is immensely disappointing.

That you can use any DE on any distro

tab completion

Proper drive mounting process. When I finally learned, it was a life changer.

I've learnt how to use Linux in preparation for the day when Windows finally goes to far.

It was so long ago there was nothing to know, really. Most pages looked fine in links, you had irssi for your social networks, mplayer for your movies (still great), mutt for email, vim for programming... It kind of just worked.

Nothing of note, really. The openness of the whole system meant that I could learn whatever I needed to know as the need arose.

I started when I was a kid, though. I had plenty of time to explore and discover. It'd be harder as an adult in a hurry.

Ctrl + R in the terminal. I never used it until I got a job using Linux, now it's probably my most used command at work and at home.
