Western PhD student Aswin Sureshkumar lost more than four years of pancreatic cancer research when his laptop and two hard drivers[sic] were stolen out of a car on April 21. He's now pleading with Londoners to not only get the laptop back, but take theft more seriously.
Still, not backing up that research when the material possibility, at least with git, has existed for five times your research's lifecycle is... astounding. And I'm not even considering FTP backups!
