Preparing to move from Ubuntu to Fedora

Hi! I’m seeking some advice and sanity check on hopping from Ubuntu to Fedora on my personal PC. I’ve been using Ubuntu LTS for almost two years now, switched from Windows and never looked back. But I cannot say I know Linux well. I use my PC for browsing, some gaming with Steam (I have AMD GPU), occasional video editing,...

NotAnArdvark,

Are you leaving behind the dotfiles because you don’t want to bring over any of your old configuration?

For whatever it’s worth, you can remove Snap support from your Ubuntu system. If you want more current software, AppImage and Flatpaks are good for that.

NotAnArdvark,

Here’s a little script I’ve put in my $PATH, called memsum:


<span style="font-style:italic;color:#969896;">#!/usr/bin/bash
</span><span style="color:#323232;">/usr/bin/ps -eo rss,command --sort -rss </span><span style="font-weight:bold;color:#a71d5d;">| </span><span style="color:#323232;">egrep $1 </span><span style="font-weight:bold;color:#a71d5d;">| </span><span style="color:#323232;">awk </span><span style="color:#183691;">'{ hr=$1/1024 ; sum +=hr} END {print sum}'
</span>

Now you can go: memsum firefox or memsum whatever and see that, actually, apps use a ridiculous amount of memory these days.

I can get Firefox up to 8GB by using things like Office 365.

NotAnArdvark,

I find the mobile interface (the browser) to be really good, at least in comparison to Lemmy.

NotAnArdvark,

Oooh, don’t do the Pinebook Pro. I think anything Pine64 isn’t unsuitable for a non-tinkerer to be using. Also, if there’s DRM content involved (unsure on Hulu), you’ll probably want to stick with an x86 CPU.

NotAnArdvark,

I’ve found that Dolphin, at least, is much slower with network mounts than a CLI-based “mount”.

NotAnArdvark,

Agreed on the latency issues. I tested SMB and NFS once and found them to be pretty much the same in that regard.

I’m interested to test iSCSI, as for some reason I think it might be better designed for latency.

NotAnArdvark,

I really appreciate this, thank you. I think I had confused myself by playing with ‘u16’ and ‘u8’ and somehow coming to the conclusion that they were matching the right side of a 32-bit string. (Which may still be true, but, I’m just masking u32s now).

This is what I ended up with, which is working the way I’d expect:


<span style="color:#323232;">tc filter add dev wlan0 protocol ip parent 1: prio 1 u32 
</span><span style="color:#323232;">	match u32 0x30d6 0x0000ffff at -16 
</span><span style="color:#323232;">	match u32 0xc92d1905 0xffffffff at -12 flowid 1:20
</span>

This sends Ethernet frames destined for 30:d6:c9:2d:19:05 to flow 1:20, and it doesn’t seem to match a second device I tested. So, all good! Thank you again.
