Some parties are amazed that I know what token ring, GPRS, TCP/IP and RS-232 mean and that I was able to program dBASE in the past. I have been mobile since about 1983 – at that time via Eurosignal and subsequent callback. I am online since 1987 – first in the BTX (Bildschirmtext) network – and this even in transit at public train terminals. I have been using the Internet since about 1995 and http://www.scheible.de exists since 1999. In order not to be considered completely outdated, I can also discuss 5G latency, recursive handlers, web APIs or quantum cryptography.
