From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

What's a unique customization on your Linux machine you think no one else has? (discuss.tchncs.de)

Just wondering since I know a lot of people quietly use a screen-area-select -> tesseract OCR -> clipboard shortcut.

I separate subjects of interest into different Firefox windows, in different workspaces -- so I have an extension title them and a startup script parse text to ask the compositor to put them in the correct workspace (lets me restart more conveniently).
I have automatically-set different-orientation wallpapers for using my 2-in-1 depending on whether I use it in portrait or landscape (kind of just for looks, but I don't think if anyone else adds a wallpaper change to their screen rotation keybind).

When I press Super + PrtSc, a bash script performs the following:

Takes a screenshot of the entire desktop (import -window root) and saves it as ~/screenshot.png..

Analyzes the screenshot to calculate the "mean brightness" value of the image. It converts the image to grayscale and determines the average pixel brightness (a value between 0 and 1, where 0 is black and 1 is white).

Checks if the image is dark by comparing the mean brightness to a threshold of 0.2. If the mean brightness is less than 0.2 (i.e., the image is very dark), it applies a negative filter to the image (convert -negate), effectively inverting the colors (black becomes white and vice versa).

Sends the image to a printer (lp command) named MF741C-743C for printing.

A kind of ‘super’ print screen, in fact.
