How to run Sybase ASE on Docker.

This will allow you to create a Docker Image with Sybase on it (in this case Syabse ASE 15.7) This demo uses Redhat but most of the steps are generic.

1) Install docker

K.R.A.U.S. in pure C

Abstract

This is a C fork of the famous K.R.A.U.S. (floor of the day) application by @jautz written in perl. The acronym K.R.A.U.S. stands for the German phrase "Kaffee-Runde auf unterschiedlichen Stockwerken". It's origin lies far in the beginning of civilisation and was once called Tempus clausum.

Since being independent of a single implementation is cruical for live threatening services this fork has been established.

Analyzing the Mebus Wireless Sensor

I have a Mebus Weather station from a discounter in my kitchen and an wireless sensor outside the kitchen window. It operates at 433.92MHz and it's blips and bits are not yet analyzed (at least by me). So lets try to read it.

I will use my crappy rtl2832 DVB Dongle (Rafael Micro R820T) for that. I'd buyed it some time ago for 1€. I'ts a little bit whiny about everything. Touch it – määää. Use it without an Powered HUB wäääää. But even that crappy thing is useful ;-)

I have some clue what to expect, so I don't start at zero. I assume the data is modulated as OOK. (On Off Keying) and I have an progam rtl_443 which can help me decode it.
