Each idea becomes a project, even if it is a potential project.<p>Projects are under a year (2008) directory under a 'work' directory (where work refers to something I'm working on, as in in-progress, not work as in job). But job stuff can go under work/{year}/projname too.<p>So then I have:<p>~/work/2006/proj1
~/work/2006/proj2
~/work/2006/projn
~/work/2007/proj1
~/work/2007/projn
~/work/2008/proj1
~/work/2008/projn<p>etc.<p>Then when something is really finished and polished, I move it to a ~/proj/projname directory. That happens only rarely. I've been reconsidering this and might start keeping everything in its original place under ~/work/{year}/projname<p>The other systems I've tried suffer from not being scalable as the years go by.<p>Periodically I back up each year (zipped and gpged) to Amazon S3 with a script.<p>Sometimes a project will span years, of course. When that happens I decide on a case-by-case basis whether to do a symbolic link back to one original project directory, or whether to start fresh at some point with a clean set of files for that project, leaving the cruft behind but still intact in a previous year.<p>Inside each project I can still use version control for the project.<p>Some projects are just repositories for ideas. Projects can be my own, or they can be me playing with third party tools I've downloaded. Even just a new open source package I'm installing might get its own project, with all files, if it's tricky and I want to make my own installation notes for future reference.<p>All project directories have a notes.txt file (or can have, at least). I have a 'tagthis' script that takes text tags as argument and adds the new tags to header lines in notes.txt in the current directory. Then later I can grep for these tags.<p>Works pretty well so far. It gives me the freedom to call anything, even an idea I don't have time to work on right now, a project and make a starting place for it. So-called projects in this scheme are very, very informal, so it's a very light weight system that doesn't get in my way, yet it keeps everything organized forever.
