Container of the Week – kaggle/python

Machine Learning is a very popular field at the moment and is something that’s in the news and geek culture a lot.  Kaggle is a machine learning competition site where you can take part in a (usually sponsored) competition to apply your skills and solve a real-world problem.

Putting aside the controversial nature of spec work (read no!spec and this Wired article for some background) Kaggle have put together a pretty nice container image for getting started with machine learning. Continue reading “Container of the Week – kaggle/python”

Clustered systems are sometimes difficult to run on a single machine, for example a laptop or desktop, as this use case is often not given a high priority by developers. Luckily, there is the gettyimages/spark image available for those who wish to quickly and easily explore the Spark environment.
