Issue #205: Bitkey

The mysterious world of cryptocurrency is quickly becoming part of everyday life. If you've been around computers and the Internet for the past five years, chances are you're either using Bitcoin or you're curious about it. This month we look at BitKey, a Debian-based Linux designed to serve in a hyper-secure Bitcoin cold storage environment.

Also inside:
* Hardware Analysis Tools – we study some leading Linux tools for diagnosing hardware problems.
* HDF5 – this hierarchical filesystem supports several programming languages and is ideal for Big Data and machine learning environments.

This issue also unveils our new MakerSpace section, with articles on a Raspberry Pi access point and a tool for building an HPC cluster with tiny Pi Zero computers.

On the DVD: Lubuntu 17.04 and Knoppix 8.1
