what's the killer app for GNU/Linux systems?
A killer app is an application that compels one to use a certain
system. On Debian lists, someone mentioned that meld, a GUI diff
utility, was killer. I can't think of any I have because I moved to
GNU/Linux for its said overall magnificence, instead of a particular
application, and today there's isn't one utility I admire so much I'd
consider such... maybe gnome-terminal, lsof, grep, top,
epiphany-browser, or less. I'd mention admirance for Blender, GCC,
Python but they are cross-platform. I'd mention GNOME, but it's a 100
apps. So I give up and ask you, what's your killer app(s)?
