Donald mentioned one earlier: command line utilities. I want a single
CLI I can deploy to my customers that doesn't make them have to
install Python or even know it's Python at all. My users write code in
all types of languages on all OSes, but I should be able to produce
one thing that they can all use. Donald himself initiated the CLI in
particular I'm talking about, but Go is picking up steam here as we
have other utilities that quickly solved the "write one thing, every
user can run it immediately, no one knows/cares what it's written in"
When I worked on Ubuntu One, I was the Windows guy responsible for
making sure the end-user experience was the same there as it was on
Ubuntu. On Ubuntu we were a part of the base install and didn't have
to worry about much. On Windows we had none of that, not even the C
runtime, so we had some pre-installer work to do, and then a bunch of
py2exe hacking to make everything play nicely and transparently.
