Starting Spark 1.2 and PySpark (and ElasticSearch and PyPy)

The latest PySpark (1.2) is feeling genuinely useful, late last year I had a crack at running Apache Spark 1.0 and PySpark and it felt a bit underwhelming (too much fanfare, too many bugs). The media around Spark continues to grow and e.g. today’s hackernews thread on the new DataFrame API has a lot of […]

What confusion leads from self driving vehicles and their talking to each other?

This is a light follow-up from my “Do self driving cars make the courier redundant?”  post from January.

On Saturday six of us attended the Future Cities Hackathon organised by Carlos and DataScienceLondon (@ds_ldn). I counted about 100 people in the audience (see lots of photos, original meetup thread), from asking around there seemed to be a very diverse skill set (Python and R as expected, lots of Java/C, Excel and other tools).
