Way back in 2010, I attended the GSoC Mentors Summit. I thought that would be a perfect time to get a new GPG key signed by a lot of people. Unfortunately, I decided to do this the night before flying out to Mountain View. With the lack of sleep, long flight, and busy weekend, I promptly forgot the passphrase to that key. For quite a while, I tried to remember or somehow guess the passphrase, to no avail.
