DSB #119


before we skate into the weekend let’s read the DSB! And this volume is full of ridiculously good articles. I would recommend the one from Computer Science & Science where you can in pure python learn how a Bitcoin really works. Or beautiful intro to Kafka from Graphs and Visualizations. Or a story about the creation of a data driven company from Business and Career. And many more. Just go through it all.

And as always, enjoy your reading.
