Time tracking: still would use @mite ... these days
I do not track time in a fine-grained way.

One tool to rule them all?

Today I'd say @github: I really love the
Trello-like simplicity and integration with issues of GitHub projects
(https://github.com/features/project-management/) GitHub team discussions
(https://help.github.com/en/github/building-a-strong-community/about-team-discussions)
is actually quite good (only a watercooler-type chat is missing)

I still develop locally, the speed and convenience of having thousands of files
locally and indexed and being able to work offline still makes this necessary. I
do travel and fast, cheap and reliable internet connectivity is (and might never
be) available everywhere I go.

But all my work results are always in the cloud. At any given time I can only
lose a few hours worth of work.

Since I gave this talk I have never lost any work at all.
