Alfred Schilken was already enthusiastic about microprocessors in the 1980s. His first experimental board had to make do with a single kilobyte of RAM and a cassette recorder as mass storage–that was in 1980.
It was a stroke of luck that his thesis at the Institute for Applied Physics in Frankfurt was about a microprocessor system.
Since then, programming has remained his hobby, but for more than 30 years he has also worked as a freelancer on projects for clients such as Telekom, Lufthansa Systems, Sybase, SAP and Deutsche Bank.
He switched from assembler to C very early, then programmed in C++, later in Java, Python and Swift. Only since working with Hammerspoon has programming in Lua become very interesting for him.
