An application and programs that use shell as their application, for example, IntelliJ IDEA use ‘idea.sh’ to run the IDE, so it would be useful for people to right-click and just create the ‘.desktop’ file right away.
Is it possible that you’re on a different TTY? The login screen used in Fedora has some problems with using the correct TTY if you don’t use auto-login. If this happens again, try cycling through them, maybe your old session is still there.
I guess this is to figure out what is also possible on Linux, and getting to know that not all problems or missing features apply to other distros.
Sometimes you can lwarn amazing stuff, like a KDE distro can be customized to your liking while a Gnome desktop is a nearly forced workflow and design but can be slightly changed with buggy extensions.
For me, it’s primarily #5: I want to know which apps are accessing the network and when, and have control over what I allow and what I don’t. I’ve caught lots of daemons for software that I hadn’t noticed was running and random telemetry activity that way, and it’s helped me sort-of sandbox software that IMO does not need access to the network.
Not much to say about the other reasons, other than #2 makes more sense in the context of working with other people: If your policy is “this is meant to be an HTTPS-only machine,” then you might want to enforce that at the firewall level to prevent some careless developer from serving the app on port 80 (HTTP), or exposing the database port while they’re throwing spaghetti at the wall wrestling with some bug. That careless developer could be future-you, of course. Then once you have a policy you like, it’s also easier to copy a firewall config around to multiple machines (which may be running different apps), instead of just making sure to get it consistently right on a server-by-server basis.
So… Necessary? Not for any reason I can think of. But useful, especially as systems and teams grow.
You most likely don’t need on device firewall if your in your home network behind a router that has a firewall. If you‘d disable that firewall as well and one of your devices has e.g. SSH activated using username and password, than there is nothing stopping a “hacker” or “script kiddy” from penetrating/spamming your SSH port and brute force your password. The person than can take over your PC and can e.g. install software for his botnet or install keylogger or can overtake your browser session including all authentication cookies or many other bad stuff.
If you are using puplic WiFi, I’d recommend a good on device firewall, or better just use a VPN to get an encrypted tunnel to your home (where you would need to open a port for that tho) and go into the internet from there.
You always need it and you actually use it. The smarter question is when you need to customize its settings. Defaults are robust enough, so unless you know what and why you need to change, you don’t.
Your GPU has a dedicated ASIC that can do the encoding simultaneously. On NVIDIA (not relevant in this case) that would be your NVENC encoder.
AMD and Intel have their own ASIC IP blocks that do encode/decode that’s part of the GPU “SoC” but wouldn’t consume GPU compute resources (eg CUs). That’s how you see people already using GPU encode with obs (non-AV1 codecs) while gaming, and really that’s how people like me using Sunshine/Parsec for the host PC for “remote” gaming (mostly for remoting into a Windows machine for the 1 game that cannot be run on Linux nor a VM due to anti-cheat). The only GPU resources you’re using are PCIe bandwidth and perhaps some VRAM usage? But I wouldn’t call it just dumping it from the CPU to the GPU, you have an ASIC that mitigates the brunt of the workload and AV1 with Sunshine has been amazing, can’t imagine now using it for recording my gameplay vids will hopefully be better than H264 (due to lower bitrates and hence smaller file sizes).
What I tend to do that scratches the distro-hopping itch is I keep an external drive with a bunch of virtual machines on it that I can spin up and tinker around with as needed, like little specimen jars lol. I think I have about 5-6 on the go at the moment. So like my actual computer runs Arch (btw), but I have VMs for NixOS, OpenSUSE, Mint and so on, as well as another one that’s as close to my main system as possible so if I want to try a weird experiment I can try it on there first to see what breaks. Just today I tried upgrading it to Plasma 6 to see what broke and the answer was everything lol.
I used to keep ones for Mac and Windows on the go too, but they tend to eat up a lot of drive space.
I can’t stand using Gnome, but it is the only one that’s vaguely touch friendly. If you pile enough extensions in there, it becomes usable. Plasma has always been a disaster for me on tablets. Maybe 6 will be better, but I’m not holding my breath.
Go with EndeavourOS. It won’t “just work”, but it will be the best compromise between confusing abstraction and low level frustrations.
Fedora is good but it abstracts a little too much away, this is great when you understand how software works, but it’s very confusing when you’re new to Linux and programming.
Arch is good, but you won’t be able to hid the ground running, you’d have to sacrifice a weekend to learn.
Go:
[Optional] Fedora
Endeavour
Arch
Learning
Ghost BSD
Void
Gentoo
Tinkering with those in that order, after about 6 months, you’ll start to feel at home.
