# [2018.11.17] IBM Badges IBM has a good collection of different online courses at https://cognitiveclass.ai. I registered there two years ago when it was called Big Data University:) So the hype changes: three years ago everybody wanted just any kind of big data, and now everybody wants some artificial intelligence. And they issue electronic badges for completing several courses in a row which can be shared on LinkedIn, the only social network I now belong to. The last badge I received more than two years ago, on the 4th of November 2016, was for the course on Scala Programming for Data Science. I tried to use Scala for DS but unsuccessfully. But the badge remained. And at yesterday's night, I got another one after completing for a course 'Docker Essentials: A Developer Introduction'. I like Docker very much, and I didn't know some details which can be found in the course.
