This hands-on workshop will provide participants with an introduction to
the Cassandra distributed "NoSQL" database management system, including
deployment, keyspace and table manipulation, replication, creating
multiple datacenters and creating users.
Participants will:
* Install a Cassandra server
* Create a keyspace
* Create a table and insert data
* Replicate data across a three-node cluster
* Replicate data across a two-datacenter cluster
* Set up Cassandra and JMX authentication
Some virtual machines will be provided, but participants will need to
bring their own laptop computer in order to access them.
It is also possible to run the exercises on your own laptop, however
some some advance preparation is advised - the workshop will require
four virtual machines or containers with the following configuration:
* minimum of 512Mb each
* minimum of 2Gb disk space each
* Debian Jessie
Paul Dwerryhouse is a Linux System Engineer with Australia Post, a job
that involves a combination of system administration, dev-ops, database
wrangling, and plenty of coding. He was first introduced to Unix in the
form of SunOS 4 in 1991 and Linux in 1994. Shortly after that, he turned
it into a twenty-year career of sysadmin and dev-ops (before the
world had given dev-ops a name) in Australia and Europe.
There will also be the usual casual hands-on workshop, Linux
installation, configuration and assistance and advice. Bring your laptop
if you need help with a particular issue.
The meeting will be held at Infoxchange, 33 Elizabeth St. Richmond 3121
(enter via the garage on Jonas St.)

Speakers:
* Lev Lafayette, UNUM Computing
* Russell Coker, How to monitor systems with "mon" and Jabber
UNUM Computing
UNUM is an abbreviation of the Universal Number format developed by John
Gustafson in response to the limtations of standard floating point
formats. UNUMS provide greater accuracy - and indeed claim to abolish
computational error altogether - with typically fewer bits and therefore
less power consumption. UNUMS claim to have no overflow, no underflow,
and no rounding. Implementations have been made in some mathematical
programming languages (e.g., Julia, Python) but hardware manufacturers
have been slow to express enthusiasm.
Lev Lafayette is the HPC Support and Training Officer at the University
of Melbourne. Prior to that he spent several years in a similar role at
the recently deceased Victorian Partnership for Advanced Computing and
has spent many years on the Linux Users of Victoria committee.
How to monitor systems with "mon" and Jabber
The "mon" program (which is difficult to Google) is a plug-in based
program to monitor a server and network services. Russell will describe
how to configure it, write plugins, and make it send alerts via Jabber.
Russell Coker has done lots of Linux development over the years, mostly
involved with Debian.
