Emacs orgmode I think pretty much close to what I want. That just a guess since I just gleaned over it's features and what people are saying about it. But to learn emacs just to use this is a bit too much. I took note in vim in outline mode - that's how my mental mode work. It would be nice if vim can record the time whenever I add new outline. Most of the todo lists or time tracker out there only allow you to define simple title and explanation of the task. If that was web based app, don't ever think of having some outlining support.
Then I noticed that it quite easy for me to rebuild my mental state on what I have done throughout the day by looking at my svn commit log or the skype chat log with my colleagues. So I stop looking for the tools and just used the history browser of our svn to compose my daily report. It work well except that not all tasks would have a commit log - or in other word something that has svn repository. I might be doing some server config or work in some web interface and all these not related to any of our svn repo.
The skype chat log gave me an idea that I maybe can use it to track my time. Each post got a time stamp so it perfect. But to whom should I chat with ? Setup new fake account ? Possible but I think there must be a better way. Enter IRC. I used irssi as my irc client and since it console based app, that mean almost no context switch in order to use it. It just few SHIFT+Arrow key away from the current console. To use public irc server for this definitely no-no. Setting up the whole irc server seem a bit over kill although is much easier nowadays thanks to apt-get.
Searching around, I found hircd - python code (in 400 lines) implementing basic IRC server. Simply run the python code and fire up irssi to connect to localhost. It just work. Automate some tasks such as automatically joining a channel, autolog on and I'm ready to go. If you work on multiple project and want to split the log, we can just create new channel but for now I stay in single channel as it easy to keep track.
Todo:-
1. Put the chat log ($HOME/irclogs) into spideroak synced directory.
2. Integrate with pormodoro technique ?
