I just wrote a quick Greasemonkey script that checks the computed style of the body element and changes it to black (you probably want to choose a different colour): (function () { if (window.getComputedStyle(document.body, null).getPropertyValue("background-color") == "rgb(255, 255, 255)") { console.log("Setting new background color..."); ...

Absolutely! You are looking for a headless installation (Virtualbox). The way to start the machine from the command line is something like: VBoxHeadless --startvm Debian --vrdp=off However you will need some way to connect. What I do is mapping ports between guest and host. With this configuration, your host 2222 port will be mapped to port 22 of your ...

Taskbar Shuffle is a small program that lets you move your taskbar items around on Windows XP and Vista. It's one of those install-and-forget applications; the only time I remember that I use it is when I try to use a computer that doesn't have it installed. ;)

Execute the shell built-in: $ set +m This works by turning off "monitor mode" so the shell doesn't report terminating background jobs. Although running the command in a subshell like: $ (sleep 2&) ...will also disable the message, the only reason it works is because monitor mode is enabled by default only for interactive shells. That is, the ...

Yes you can change the color. As explained here you should Windows: go to %appdata%/mozilla/firefox/profiles and open the folder in there.

Your school's IT administrators are using either group policy or a third party program to restrict what you can do with your background. I'd say that's a smart policy for them to implement, considering what many high school students might choose to use as their background when they have access to the web or USB flash drives. (I'm assuming high school based ...

Autohotkey. I've never come across something it couldn't do, what's it struggling at? (Apart from autohotkey, an application launcher like Executor, Launchy, or the previously mentioned Enso.)

disown does not change the programs STDOUT/ERR. They will still go to wherever you redirected them (using > etc.). If you did not redirect them, they'll continue to go into the terminal you started the program from (until you close that terminal, in which case they'll be discarded). To illustrate, run this in a terminal: bash -c 'while true; do sleep 1; ...

I had the same issue. To edit the background: Click on View -> Slide Master Click on View -> Slide Master again. All the background images will become editable and copy-pasteable. Definitely not intuitive.

What do you want to achieve exactly? If you just want to modify the appearance of LibreOffice, without modifying the output, you could set a custom color for the document background: Menu "Tools" -> "Options" -> "Appearance" -> "Document Background".

The email back from Thomas Dickey (xterm's maintainer) has this. Note in particular the part about "?". The Ps = 4 refers to (OSC Ps ; Pt ST) where OSC (the "Operating System Control" prefix) is ESC ] and ST (the "String Terminator" suffix) is backslash.
