If you've ever worked with the command prompt on a Unix-based computer, you're likely familiar with SSH (Secure SHell), which is a program and a protocol that allows you (yes, you!) to securely access a remote system. While SSH has certainly earned the "Secure" portion of its namesake over the years, it's functionality as a shell has ironically received very little attention, and has begun to show signs of age and obsolescence: SSH doesn't work very well on mobile connections, and its support for Unicode is buggy and incomplete. A group of MIT researchers think they've found solutions to these problems, and have created Mosh as a potential successor to SSH, which fixes many of the old protocol's annoyances and shortcomings, while retaining all of SSH's security features.
The Wall of Death is a great song by venerable British folkie Richard Thompson (covered by REM among others) concerning a carnival sideshow attraction involving a large wooden cylinder and at least one motorcycle (previously on metafilter). The Wall of Death is also the latest permutation in mosh pit chaosity.
