“jengelh” stems from the traditional username creation
pattern used in scientific institutions — ancient systems seemed to have a
limit of eight characters, and the usual pattern was taking one character from

February 14, 2009
Generally I use xterm because that is available on about every UNIX workstation, or where not, “derivates” (allow me to use this terminology even if it may not apply) like rxvt are available on, for example, MSYS (system around MinGW for Win32).
