This week's book giveaways are in the Jython/Python and Object-Oriented programming forums. We're giving away four copies each of Machine Learning for Business: Using Amazon SageMaker and Jupyter and Object Design Style Guide and have the authors on-line! See this thread and this one for details.
The first 'program' I made was in BASIC with a pencil binary marking boxes on a card which could be run in the SARA computer in Amsterdam. But that's way back (when a computer was as big as a living room). Later on I learned (in order of appearance): MSX Basic, Z80 assembly, Turbo Pascal, C, C++, PHP and now I'm looking into Java.
