An interesting ad. I haven’t seen other companies recruit with an opening paragraph like this.

Do you know who Kernighan, Ritchie, and Pike are? Have you ever met any of them? Do you know what AWK stands for? Do you know why it is a bad idea to write shell scripts in ‘csh’? Do you know how to use ‘ed’? Do you now what ‘L1-A’ does? Do you understand the limitations of SysV, FreeBSD, Debian, and RPM packaging systems but also understand that they are a necessary evil? Then you, quite probably, are the kind of person we are looking for.
