Meeting 14 August: Bash Shell

Mon, 2014-07-21 11:00


Topic: Bash Shell
Presenter: Brian Gerard
When: Thursday, 14th August 2014, 7pm (pizza from 6.45pm)

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.

Synopis:
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/

April 10 Meeting: Ansible

Mon, 2014-02-24 14:29


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.

March 13 Meeting: Docker

Topic: Docker
Presenter: Vincent Batts

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: YouTube (lost the start of the meeting)

Abstract:
What is docker (https://www.docker.io), and how can it help me?

Linux containers are self-sufficient ways to deploy isolated applications for testing, developing, or running applications at scale. Come for a workshop on how to leverage this technology for more robust continuous integration, and developing/deploying across a diverse landscape of distributions.

We'll go over the fundamentals:
* Building a image for your application (if you're not a developer, that is ok :-)
* Wiring up that image for your use case
* Shipping that image (or even publishing it for others)

Feel free to bring your questions on docker-based solutions!

Vincent Batts is a Senior Software Engineer at Red Hat. He has specialized in content delivery to customers, and more recently joined the Openshift team. Vincent's years of Linux and open-source involvement, including development work on Slackware and Fedora, have lead to exciting new opportunities with OpenShift and the docker community.

This will be followed with a high-level overview of cryptography. We'll look at where it's been made easy to use, and were it's not so easy. Then we will dig into the details of using GPG from the command line, to encrypt documents and to verify software packages.

October 10 Meeting: Choosing a secondary DNS server, now with data!

Mon, 2013-08-12 09:33

Topic: Choosing a secondary DNS server, now with data!
Presenter: Aaron Joyner
When: Thursday, 10th October 2013, 7pm (pizza from 6.45pm)
Where: NC State Engineering Building II Room 1025, Centennial Campus
Parking: The parking decks and Oval Drive street parking are free after 5pm
Map: Google Maps
Video: YouTube

Abstract:
Are you responsible for a DNS domain, perhaps professionally, or a "vanity" domain for your personal email?  Have you given much thought to the DNS resolvers for that domain?  Every domain requires at least one DNS server, and everyone has probably heard that they should have a geographically disparate secondary server to hedge against catastrophic outages (network, building, etc).  Assuming you don’t have the luxury of a globally distributed set of datacenters, where should your secondary DNS server be hosted?  This talk will present one man's quest to answer that question, along with the data used to visualize and understand the available options.  There will also be a brief discussion of how that data was collected, and open source code (in Go, http://golang.org) to do it yourself.

Bio:
Aaron S. Joyner is a Sr. Systems Engineer in the Site Reliability Engineering (SRE) group at Google. He has been working as a SysAdmin for more than 15 years at companies such as Global Knowledge, Intrex.net, and MWG Biotech.
