Please familiarize yourself with them


2) All posts must end with a '?'This is sort of like Jeopardy. Please phrase all post titles in the form of a proper question ending with ?


3) No spamPlease do not flood the community with nonsense. Actual suspected spammers will be banned on site. No astroturfing.


4) NSFW is okay, within reasonJust remember to tag posts with either a content warning or a [NSFW] tag. Overtly sexual posts are not allowed, please direct them to either !asklemmyafterdark@lemmy.world or !asklemmynsfw@lemmynsfw.com. NSFW comments should be restricted to posts tagged [NSFW].

I need to quench my thirst for knowledge and learn something new just for the sake of it.

I've already learned:

  • Equations and pivot tables in Excel

  • Vector graphics in Inkscape

  • Music mixing in rekordbox

  • Personal VPN on a raspberry pi 4 with OpenVPN

  • LAMP stack web hosting

  • Streaming & video capture with OBS

  • Manual & automatic backups with FreeFileSync

Things I'm open to:

  • FOSS (even beta) or free-as-in-beer software

  • A high or low learning curve

  • Tools for niche fields that I'd otherwise have no reason to learn

Ardour, it's a FOSS Digital Audio Workstation

https://ardour.org/

[–] LordCrom@lemmy.world 1 points 3 minutes ago

Have you gotten ardour to accept input from guitarx's USB interface? I hate falling g back to windows stuff for audio recording.

[–] hildegarde@lemmy.blahaj.zone 5 points 1 hour ago

Lilypond. Its music software. Learning it will keep you occupied for at least a week.

This is just pure evil

[–] AnarchistArtificer@lemmy.world 1 points 27 minutes ago

I don't have any suggestions, I just want you to know that you're delightful

[–] Emerald@lemmy.world 2 points 54 minutes ago

You could get JOSM and become an OpenStreetMap editor. https://josm.openstreetmap.de/

Also install gentoo.

[–] Hamknight@lemmy.world 1 points 58 minutes ago

Voicemeeter potato. Enjoy learning how all your audio devices work, and how to add noice effects.

Use graphviz dot files to draw a graph

Draw some graphs from data files downloaded from public university data sets in GNU Octave

Write a review of the process and tools with embedded images and code in LaTeX

Stage lighting controls are extremely fun to learn. DMX, ArtNet, etc. QLC+ is free and open source, there are TON of other ones as well (like controlling big stage lights with a Wii controller so they move like you).

There are simulators, but the prettiest I've seen so far is https://github.com/AcChosen/VR-Stage-Lighting. Despite its name, you don't need vr for it but if you do, you can watch your lightshow as if it was real!

Blender and buy a 3D printer afterwards

And remember when you learn emacs to also learn org-mode!

[–] wibble@reddthat.com 5 points 4 hours ago

Vi/vim counterpoint. Learning to quit vim will get them very far in life

[–] Thwompthwomp@lemmy.world 3 points 5 hours ago

Now that is the gift that keeps on giving! I also like the implication that one can "learn" emacs.

[–] sem@piefed.blahaj.zone 8 points 6 hours ago

You can do really neat thinga in QGIS -- like make your own professional quality maps, make map animated gifs, etc

[–] Digit@lemmy.today 11 points 9 hours ago

some suggestions for your consideration in order of empowerment and learning curve first,

  • AWK
  • ffmpeg (~ & imagemagick ?)
  • bash, zsh, or fish
  • kew (it's just a really simple nice tui music player, no fuss). (... "Am I the only fun one in Digit's list here?" -- kew)

n_n

Some other things that sprang to mind, (generally tending to more gui things, some distro/packagemenent things)... audacity/tenacity, fontforge, gimp, gentoo and portage, bedrocklinux and brl, peertube self hosting, forgefed self hosting, suckless.org's tools, CRUX or KISS/Carbs, just playing around in stellarium, playing around in pioneer space sim, learning how to evade humanity's detection as an ai in the game called singularity, ;3

Oh... Here's an idea for you... Learn a text editor.

Think it's not fun?

Depends on which text editor you pick, and how much the fun suits you. ... Emacs has so many things (including games, like tetris and doctor). Even neovim has some extra things (~ opencode runs on neovim... tho it's not the same, lol). Or maybe you want something simpler, like nano, mcedit, or fin (I wrote fin, don't use it, it's scruffy... and only able to do that from learning some of the things mentioned, and more).

Yay for learning. Yay for asking for what other fun things to learn. Good post. Good question. ... Sorry my answers were not better. Heh. Caught off guard, answered just what first sprang to mind. n_n Doubtless many other more fun things exist.

idk the software but multitrack audio editing sounds fun.

[–] ExLisper@lemmy.curiana.net 16 points 13 hours ago (1 children)
[–] onipa@feddit.org 8 points 9 hours ago

or vim with vimtutor

[–] ascendings@fedia.io 19 points 15 hours ago

I'd say GIMP for photo editing would be a good one to learn. It's come in handy in a pinch both at home and at work when I've needed something done up real quick.
