Tonight, I spent time on Google's foobar coding challenge. It was good opportunity to hone my Python skills. I'll update once I crack level 3.
I have also registered and started another massively online course. This time CS100.1x, Introduction to Big Data with Apache Spark offered by BerkeleyX. Time commitment for this one looks minimal. The syllabus estimates 25 hours over 5 weeks. I'll update with a recap afterwards.
