Just another software geek... and possible polymath (I aspire to that title, at any rate).

comment What software can I use to do live screen-casting in linux?
I'm fairly sure vnc has the ability to do multicast... if anybody still routes those packets. a web search for "vnc multicast" does return some hits, though. (Though they seem to be talking about different versions, and I could have sworn I remembered it being built in, as of c. mid-to-late 1990s... but I wasn't really using it myself, merely watching others do so.)

comment How to make functions created in a bash script persist like those in .bashrc?
If you're going to quote the conf_file variable in your source command, it's probably good practice to quote it in your [[ pseudo-command, too. This apparently isn't actually required, since bash seems to expand variables differently inside of it than out, but it would help prevent an accidental removal of them in other places... To wit: compare: foo='test this thing'; touch $foo; [[ -f $foo ]] && echo true || echo false versus foo='test this thing'; touch "$foo"; [[ -f $foo ]] && echo true || echo false (run these from an empty directory for improved sanity)

comment tmux vs. GNU Screen
This is an interesting distinction. I'm sure each of these has advantages, for different use cases. (tmux advantage: two people attached to same tmux session e.g. for remote pair programming would always see the same thing; screen advantage: one person attached to the same screen from two places for two different purposes can have two different views, even simultaneously (with, say, side-by-side (OS/windowmanager-level) windows).)

comment Unix command that takes no arguments
Are you looking for a command that would error if given arguments, or that just don't process their arguments? I'm not immediately thinking of any in the former category (though one would be easy to create, and they may well exist), but the latter category has various examples. And of course there are many unix commands that do something useful without any arguments, but I'm guessing that's not what you're asking.
