You can put them onto your Plasma wallpaper and/or lockscreen background with plasma-wallpaper-application: https://invent.kde.org/dos/plasma-wallpaper-application

(thought I'd share that since its raison d'être was to put Asciiquarium there :))

Cool

What are those commit messages?

seba_dos1•2h ago

Protip for the author: --allow-empty ;P

xxs•1h ago

instead of --amend?

seba_dos1•1h ago

Instead of adding or removing a space in random files when making cute and useless commit logs.

xxs•1h ago

that's what I meant - "amend" would not create any extra commits/entries

seba_dos1•1h ago

...which is not a helpful advice when what they clearly wanted is to create a bunch of extra commits.

kevincox•1h ago

But that doesn't change the files, so it won't show up in the tree view as the user is trying to accomplish.

AI slop - or worse, somebody trying to hide something.

Looks like an attempt to make the main GitHub page (the part above the README) display something interesting. It is messed up now because of further commits, but you can see what it looked like at the time here:

See the spread-the-word script in https://github.com/attogram/bash-screensavers/tree/main/spot... This script generates a series of shell commands to create a "spotlight" message on the main GitHub repository page. It does this by generating commands that make trivial changes to the top 12 files and directories and then commit those changes with custom messages.

Doesn't work for me on MacOS:

I get "mapfile: command not found"

SeeManDo•1h ago

Same here

SeeManDo•1h ago

Bash Screensavers v0.0.27 (Mystic Shine)

./screensaver.sh: line 79: mapfile: command not found 1 .

(Press ^C to exit)

Choose your screensaver: 1 404 Screensaver Not Found:

Oh no! Screensaver had trouble! Error code: 1

seba_dos1•1h ago

Get a Bash that's not ancient. mapfile is there since version 4.0 from 2009.

SeeManDo•1h ago

Seems to be a old version of bash installed and used by default on macos

SeeManDo•1h ago

Even after updating still getting the same error

checked active bash version:

echo $BASH_VERSION

5.3.3(1)-release

seba_dos1•44m ago

What's relevant is whether "/usr/bin/env bash" runs the correct one.

huhtenberg•1h ago

For the 'life' screensaver it might make sense to use half blocks as a base rendering unit. ASCII 220 and 223.

Evidlo•1h ago

Why does the cursor flicker around the screen for most of these? Does it have something to do with not double buffering the display?

attogram•1h ago

Some artifact from asciinema maybe. Only shows up in the preview gifs. Needs to be fixed!

PessimalDecimal•57m ago

I've used Emacs for years but just recently learned about zone.el. I wonder if this is based on it too. I see some of the same screensavers here.

blenderob•53m ago

Wow! The copyright of zone.el goes back to 2000. But this is the first time I hear about it! How did you find this gem?

This reminds me of having a screensaver in DOS.
