buffer overflow

I wanted my wallpaper to change whenever I logged in, but found no easy way to do this. In KDE you can tell it to slideshow the wallpaper, but that’s not what I wanted. Just, when I log, switch to a new wallpaper. I want to say “pick a file randomly out of the files in a directory and set the wallpaper on all the desktops”

So here’s my ruby script.

#!/usr/bin/env ruby
 
require 'rubygems'
require 'getopt/std'
 
module RandomArray
  def random
    self[rand(size)]
  end
end
 
opts = Getopt::Std.getopts("d:n:")
 
raise "No directory given. Use #{__FILE__} -d <directory> -n <number of desktops>" unless opts.include?('d')
raise "No desktop count given. Use #{__FILE__} -d <directory> -n <number of desktops>" unless opts.include?('n')
 
DIR = opts['d']
 
image = Dir.entries(DIR).map do |e|
  "#{DIR}#{File::Separator}#{e}"
end.reject do |e|
  File.directory?(e)
end.extend(RandomArray).random
 
1.upto(opts['n'].to_i) do |i|
  system("dcop kdesktop KBackgroundIface setWallpaper #{i} #{image} 8")
end

I realize python has some dcop stuff and you can sort of just call it, and ruby probably does too, but I couldn’t find good docs on any of that, and I just found the command line thing to call, so I hacked this up in ruby, and it works quite well.

I realize the reject should really be done before the map, and originally had it like that, but then the File.directory? call was more complicated, so I changed it to this.

Make a bash script in ~/.kde/Autostart and add the following.

#!/usr/bin/env bash
 
random-wp.rb -d $HOME/wallpaper -n 4

I have 4 workspaces, hence the 4 at the end. Alter appropriately.

Stuff like this makes me sick. While I realize this incident isn’t because they are in Texas, or anything like that, it doesn’t exactly help the stereotype Texas and it’s people have.

This looks cool. I will have to try it out.

I finally got around to fixing my stupid screen not shutting off when I closed the lid. Here is the fix I used.

I was using kuake, but this is better. Insta terminal on KDE! I usually have konsole running, but this might obsolete that…
