When I'm disconnected, I tend to just leave a bunch of comments in code with ONLINE in them and what I need to look up and recover my train of thought.
I then switch to working on a different part of the program, or a different program altogether, and come back to them when I'm next online.
This has worked pretty well for me so far, as long as I'm not under a time crunch.
That is a good point. Another tag like TODO and FIXME :-)
I've noticed that I eventually get "push anxiety" when I work offline for longer periods. Once we even had to do a detour on a road trip from Poland to Helsinki to stop by a colleague's office in Sweden to be able to push code I had written on the way. I guess I simply don't trust my laptop...
Push anxiety, excellent.:w I suffer from write anxiety.:w I've been helping someone learn to program,:w and as I watch him write code I feel more tense the longer he goes:w without writing his file.:w When I mentioned this as a matter of human interest,:w and as an introduction to why you should save often,:w he laughed.:w I'm quite confident I will have the last laugh on him before he truly learns that lesson.:wq
