UPDATE: I completely forgot to mention a critical factor: These tools need to be freeware or open source (FOSS). There are a ton of great utilities around which you can drop money on, but we’re focusing on FOSS toys.
One of the parts in the book James and I are writing covers miscellaneous Windows Utilities. This chapter covers miscellaneous utilities developers find handy, but don’t fit easily in other categories like Troubleshooting, Build, Editing, etc. We’re already writing about a good list so far: Cygwin (more than a utility, but a good fit), Cropper, SlickRun, TaskSwitchXP, ZoomIt, VMWare and Magnifixer.
However, we’re always interested in more cool tools to write on.
Do you have any other developer-oriented utilities you think are the bee’s knees?
