Meeting 14 August: Bash Shell

Synopis:
As Linux users, we spend a lot of our time on the command line, in the shell. And the most popular shell in Linux-land is bash, GNU's Bourne-Again shell. Many users never move beyond the simple execution of a few well-known commands, but there is a lot more that can be done if you learn how.

In this talk, we will go over some less-frequently-used options to some well-known commands and show how they can be put together into more powerful command line constructs. From there, we will explore some of the more useful built-in features of bash and demonstrate how they can be assembled into new commands.

The goal is to give the audience a glimpse into the real power of bash, along with some guidance on how to incorporate some of that power into their own environments and daily workflows.

Bio:
Brian Gerard has been working with various *nixes, and Linux specifically, since the mid-'90s, as a Systems Administrator, a Software Engineer, and an end user. After eight years developing abuse defenses for Yahoo! and training their engineers, he now uses his expertise doing deployment automation and security work for WebAssign.

Whatever the role, throughout his career he has found the shell to be an invaluable tool; first using csh, eventually moving to tcsh, and finally (after a friend made it his personal mission to get him to switch), bash. His startup files are the stuff of legend, he has more aliases than your average mafioso, and his prompt decorations have been known to bring tears of joy to the eyes of even the most jaded of sysadmins.

July 10 Meeting - Hadoop

What is Hadoop?
The Apache Hadoop software library is a framework that allows for the distributed processing of large data sets across clusters of computers using simple programming models. It is designed to scale up from single servers to thousands of machines, each offering local computation and storage. Rather than rely on hardware to deliver high-availability, the library itself is designed to detect and handle failures at the application layer, so delivering a highly-available service on top of a cluster of computers, each of which may be prone to failures. (http://hadoop.apache.org)

This introduction to Hadoop will briefly cover its history and then dive deeply into where the Hadoop ecosystem is today using the Hortonworks Data Platform (HDP). After the history session we'll talk about the main components, cluster operation, software development and tie the ecosystem components together. Lastly, there will be a demonstration of the popular tools used for data manipulation and querying.

If you wish to follow along with the demonstration download the HDP Sandbox VM here: http://hortonworks.com/products/hortonworks-sandbox/

Kristopher Kane is a systems architect at Hortonworks and lives in Fuquay-Varina.

May 8 Meeting: SystemD


Topic: SystemD
Presenter: David Both
When: Thursday, 8th May 2014, 7pm (pizza from 6.45pm)
Where: NC State Engineering Building II Room 1021, Centennial Campus
Parking: The parking decks and Oval Drive street parking are free after 5pm
Map: Google Maps
Video: Hangout OnAir (during the meeting)
Slides: SystemV-vs-systemd (Presentation), SystemV-vs-systemd (Lab Project)

Abstract:
This presentation will briefly review the Linux boot process and the old SystemV startup process. It will then discuss in more detail the startup process using systemd, and the reasons for creating the new systemd daemon and some of the advantages it provides. We will also discuss configuration files and some of the more common commands required to cause systemd to do our bidding. Backward compatibility will also be covered.

April 10 Meeting: Ansible


Topic: Ansible
Presenter: Joseph Tate
When: Thursday, 10th April 2014, 7pm (pizza from 6.45pm) (Re-scheduled from Feb)
Where: NC State Engineering Building II Room 1021, Centennial Campus
Parking: The parking decks and Oval Drive street parking are free after 5pm
Map: Google Maps
Sponsor: Ansible, Inc.
Video: Youtube (recorded using Webcamstudio)
Slides: An Introduction to Ansible

Abstract:
Ansible is a powerful remote system management tool like Puppet or Chef for configuration management and like Fabric and Capistrano for application deployment. Ansible can also do system provisioning through modules for various cloud providers. As a hybrid, Ansible is a little more step-wise than a pure configuration management system (which makes it better for deploying software and dealing with multiple system tiers) and more declarative than your typical remote automation framework (which makes it easier to manage dissimilar systems, even systems not originally deployed with Ansible). It has very minimal client requirements and no deployed client agent. Joseph will introduce Ansible for single tasks and highlight some of the built in modules and what you can do with them. Then he will jump into best practices for stringing multiple tasks together into Ansible Playbooks (especially how not to repeat yourself). Finally, he'll tie it all together with Amazon EC2 to show how to fire up spot instances using a base image, configure it with a set of software and configuration, do some work with it, and finally tear it all down.

Bio:
Joseph was introduced to Linux while in college in 1998, and while he didn't understand Debian then (and arguably still doesn't), did manage to download RedHat 5.0 onto a bunch of floppies and install it successfully; he then tried never again to look at Windows with varying degrees of failure. He cut his first open source teeth on PHP earning commit access to a couple of modules in 2001, and since has contributed to many other projects. He now contributes most regularly to CherryPy and a couple of pet projects. A long time RPM slinger, he worked for the now defunct rPath from 2005-2009 building system configuration and distro building software. Now he runs the completely virtual infrastructure and continuous testing and build system for a small SaaS startup in California from his evil lair^W^Wbasement. Joseph holds a BSE in Electrical Engineering and Computer Science from Duke University, served as Publicity Chair of TriLUG from 2004-2006, and has reluctantly been awarded three software patents. He thinks KDE is the best desktop to run multiple terminals in, and VIM is the best editor.
