Meeting 14 August: Bash Shell

Topic: Bash Shell
Presenter: Brian Gerard
When: Thursday, 14th August 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

Video: YouTube
Slides: PDF and code on GitHub

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.

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

Topic: Hadoop
Presenter: Kristopher Kane
When: Thursday, 10th July 2014, 7pm (pizza from 6.45pm)
Where: NC State Engineering Building II Room 1021, Centennial Campus

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. (

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:

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