Cassandra Install on Digital Ocean

The systems

The 512 MB/1 CPU system is too small. The 1GB/1 CPU can technically run Cassandra but it is too small. You should likely start with 2GB/2 CPU systems but expect to upgrade.

Select them in the same region for right now.

I went with Ubuntu 14 and the commands here will presume that. The commands were done from the root account. This will also presume that you are doing a multi-node cluster (3 is

Setting up Pi Zero OTG - The quick way (No USB keyboard, mouse, HDMI monitor needed)

More details - http://blog.gbaman.info/?p=791

For this method, alongside your Pi Zero, MicroUSB cable and MicroSD card, only an additional computer is required, which can be running Windows (with Bonjour, iTunes or Quicktime installed), Mac OS or Linux (with Avahi Daemon installed, for example Ubuntu has it built in).
1. Flash Raspbian Jessie full or Raspbian Jessie Lite onto the SD card.
2. Once Raspbian is flashed, open up the boot partition (in Windows Explorer, Finder etc) and add to the bottom of the config.txt file dtoverlay=dwc2 on a new line, then save the file.
3. If using a recent release of Jessie (Dec 2016 onwards), then create a new file simply called ssh in the SD card as well. By default SSH i

	# Recursive backtracking algorithm for maze generation. Requires that

	# An implementation of Kruskal's algorithm for generating mazes.
	# Fairly expensive, memory-wise, as it requires memory proportional
	# to the size of the entire maze, and it's not the fastest of the
	# algorithms (what with all the set and edge management is has to
	# do). Also, the mazes it generates tend to have a lot of very short
	# dead-ends, giving the maze a kind of "spiky" look.
