Execstack is a great tool for learning and training on Linux. It is a program which sets, clears, or queries the executable stack flag of ELF binaries and shared libraries. When I was looking to install it I took me a bit to find which package to install it in.
You can install with :
Ubuntu
$ sudo apt-get install prelink
Arch Linux
| #!/bin/bash | |
| random_wallpaper="$(find $1 -maxdepth 1 -name *.png | shuf | head -1)" | |
| actual_size="$(identify -format %wx%h $random_wallpaper)" | |
| target_size=$(xrandr | head -n 1 | awk -e '{OFS=""; gsub("[ ,]+","",$10); print $8,"x",$10;}') | |
| if [[ "$actual_size" != "$target_size" ]]; then | |
| convert "$random_wallpaper" -background black -gravity center -scale $target_size -extent $target_size png:- | i3lock -i /proc/self/fd/0 | |
| else | |
| i3lock -t -i "$random_wallpaper" | |

This example illustrates how QSortFilterProxyModel and QAbstractListModel can be used to display a list of filterable items in QML and Python.
