Jeskola Buzz has a pretty interesting back story: >The development of the core program, buzz.exe, was halted on October 5, 2000, when the developer lost the source code to the program. It was announced in June 2008 that development would begin again, eventually regaining much of the functionality.
Sounds like a real bad day.
Yeah it was pretty spectacular. The author was a bit paranoid, had never shared his sources with anyone or backed them up anywhere or version controlled them to a remote SVN server or anything like that. And then his hard drive failed and Buzz development was over. IIRC there even was a community-organized crowdfunding campaign to fund some fancy data recovery company to try and revive the hard drive so he could get the sources back (not sure if this ever turned out happening).
