June 2013 Regular MUG Meeting

We meet at 6:30pm on the second Tuesday of each month at the Farmington Community Library.

Our Topics include:

Raspberry Pi

Raspberry Pi is a credit card sized computer that runs Linux for $35. It’s built to use peripherals that many homes or schools have lying around, and it’s got a set of general-purpose I/O pins that come in handy for the kinds of DIY electronics projects made famous by the Arduino and friends. Though initially inspired by the 8-bit machines of the 80’s that introduced kids to the wonders of computing and electronics, it’s also found its way into the workshops and entertainment centers of adults. Les Ochard will present a quick overview of the Raspberry Pi & the Foundation behind it. He’ll also talk about things people have done with the Raspberry Pi, and attempt a quick demo of it hooked up to a Macbook, an Arduino, a LCD display, and more.

Les Orchard is a web developer for the Mozilla Corporation who collects small linux computers and likes seeing what kinds of things they can plug into.

We meet at 6:30pm on the second Tuesday of each month at the Farmington Community Library

Big Data

Speaker: Sharan Kalwani

These days one cannot swing a dead cat without hitting the buzz phrase “Big Data”! So what is all this hoopla (or Hadoop) all about really? Many years of technology advances in processing power, cheaper storage, faster I/O capabilities, cheaper memory chips, greater WiFi coverage, widespread mobility
have *all* contributed to a vast explosion of information in all shapes and forms. The term “Big Data” first came into usage about 6+ years ago, when a major database scientist wrote about a new paradigm of science (sometimes also called the fourth pillar) – one which is based on letting the data tell us what
was really going on, as opposed to guessing up a hypothesis/theory and then running with it. Of course, our beloved Linux platform was a key enabler in this and the Hadoop framework, which was born from an engineer’s work, originally inspired by a couple of papers written by Google’s team. This talk will dwell on many “Big D” (pun intended!) topics, history, what this means in technology terms and more importantly the impact on society.

Sharan Kalwani is an HPC specialist with 20+ years of experience. Sharan has degrees in both Engineering and Computer Science. He has worked in IT architecture, systems deployment, software development, OS kernels, UNIX device driver writing, networking and compilers. He has also worked on
several engineering, technical & scientific applications. Sharan has worked with several computing vendors such as Cray Research, Silicon Graphics Inc. (SGI), etc. He has managed several very large HPC sites with corporate organizations such as General Motors (GM) and research universities (KAUST). Sharan is a member of IEEE/Computer Society, USENIX, Michigan User Group and the ACM.

We meet at 6:30pm on the second Tuesday of each month at the Farmington Hills Library.

Introduction to Ceph

As the size and performance requirements of storage systems have increased, system designers have looked to new architectures to facilitate system scalability. Ceph is a fully open source distributed object store, network block device, and file system designed for reliability, performance, and scalability from terabytes to exabytes. This talk will describe Ceph architecture, the goals of the project, and why you should care about yet another storage system.

Bio: “Patrick McGarry is a community manager for Inktank, the consulting services company helping users to learn and deploy Ceph. An experienced community manager, gamer, mischief maker, and all around geek, Patrick spent five years writing and managing Slashdot under the nomme du keyboard ‘scuttlemonkey.’ Patrick enthusiastically helps companies to understand and adopt Open Source ideals and continues to be a strong advocate of FOSS on the desktop and in the enterprise. He still hates writing these bios.

Reduce your SPAM in 5 easy steps, guaranteed!

Running your own mail server can be a great experience, but the ever-looming threat of SPAM can suck the fun right out of it and make you wonder if moving your mail server to Google Mail or some other service would be better. IN this short tutorial, Craig Maloney will show several easy techniques you can put into place today in order to keep your mail server from accepting SPAM. He’ll also touch briefly on the SPF protocol and how you can help lower SPAM back-scatter, and help get your mail through witl little hassle. We’ll also cover why Bayesian Spam Filtering and Greylisting are overkill for a problem that can be easily addressed on a low-powered machine. Get your mail queue back, and take back your resources, garanteed, or your money back.

Bio: Craig Maloney is a member of the MUG Board, and frequent contributer of talks. He hosts the podcat Open Metalcast, and co-hosts Lococast with Rick Harding. He too hates writing these bios.

IPV6

There’s a lot of buzz about IPv6.  IPv4 depletion in Asia and Europe.  LTE/4G devices bringing IPv6 to my perimeter network.  US Internet backbone IPv6 penetration of over 2% with a 150% annual growth rate.  Do we really need IPv6?  How does it differ from IPv4?  What’s the impact and when should I consider deploying it?  What do I need to get started?  Jim Small will help us dive into the why, how, where, what,  and when of IPv6.

James R. Small is a Senior Consultant with CDW where he advises on, architects, and implements IT solutions for a diverse array of businesses and government organizations.  He is an adjunct professor at Macomb Community College as well as a frequent speaker at user groups and conferences.  Most recently he spoke at the annual gogo NET Live IPv6 conference in California and was a panelist on the Packet Pushers IPv6 Security podcast.  His focus is on security, networking, and leveraging tools for automation and orchestration including several large scale global projects for GM and Dow.  Jim has over 17 years of experience in IT and when he’s not beta testing, he enjoys running, playing hockey with his sons, and traveling with his family.

History of MUG

Would you believe MUG. has been around for *mumble mumble* years? We’ve lived through the rise of UNIX, countless proclamations of UNIX’s death, and the rebirth of UNIX in Linux. It’s been an interesting ride thus far, and we’ll take the latter half of the meeting to talk about the history of MUG, as well as reminisce about technologies past, present, and still to come. If you’re an alumni of MUG and want to come and share your stories, you won’t want to miss this meeting. Bring your MUG artifacts and stories, and hear the history of Michigan’s longest-running UNIX User’s Group.

And we’ll also have our normal MUG meeting features: Jobs Looking For People, People Looking for Jobs, news and events, and much much more.Hope to see you there!

Two Factor Authentication

Michael Tiller will give a presentation on his thoughts and experience involving two-factor authentication.  He’ll discuss a couple of different ways that two-factor authentication can be used to help reduce the risk of having your sensitive information and/or accounts compromised.  Dr. Tiller was the head of IT for Emmeskay, a Plymouth based engineering consulting company.  He’s currently the President of Xogeny, a local engineering software company.  He’s been using Linux since version .95 ;-)

OAuth

OAuth, the Open Authorization standard, provides a way for users to share their information across websites without divulging their password to those sites. Will Fuqua will discuss what OAuth is, how it works, and how you can use OAuth in your own apps to interact with popular sites such as GitHub, Google and Twitter.

And we’ll also have our normal MUG meeting features: Jobs Looking For People, People Looking for Jobs, news and events, and much much more.

Hope to see you there!

Ubuntu 12.10

The Ubuntu Michigan Loco will discuss what’s new with Ubuntu 12.10. We’ll highlight new features with the OS, and have an open discussion about what to expect with the new release. We’ll also have Ubuntu 12.10 discs to hand out at the event.

LTSP Stack Exchange

Jim McQuillan would like to get a Stack Exchange site running for LTSP, and he needs your help! Jim will discuss the basics of Stack Exchange, and highlight what the LTSP Stack Exchange site needs to do in order to graduate from the beta state.

Book swap

Aludra Fuse-based Filesystem

Scott Balneaves, system administrator for Legalaid Manitoba, Canada has been working on a project to create a Linux filesystem backed by a postgresql database.  The idea is, users can store their Openoffice documents in a filesystem hierarchy, but behind the scenes, the documents are actually being written to a database.  Scott is using the FUSE (Filesystem in Userspace) feature of Linux to create a translation layer that converts the filesystem calls into sql instructions.

Raspberry Pi

The Raspberry Pi presentation will not be happening this meeting. We will advise if and when it will be presented.

Fishbowl

We’ll be bringing back the Fishbowl. From Wikipedia: “A fishbowl conversation is a form of dialog that can be used when discussing topics within large groups. Fishbowl conversations are usually used in participatory events like Open Space Technology and Unconferences. The advantage of Fishbowl is that it allows the entire group to participate in a conversation.” Dave Satwicz will start the moderation off, but the discussion will be driven and led by you, the participants. This is a unique way to get some really engaging conversation about topics that you want to learn more about, or topics you haven’t heard yet. Please bring some ideas of what you’d like to talk about. We had a lot of fun with the discussions the last time we had a Fishbowl, so come on out to learn more.

And we’ll also have our normal MUG meeting features: Jobs Looking For People, People Looking for Jobs, news and events, and much much more.

Hope to see you there!

Juju

Ryan Kather will be discussing Juju, a next generation service deployment and orchestration framework developed by Canonical Ltd. Juju has been likened to apt-get for the cloud. With Juju, different authors are able to create service “charms” independently that work well together.

Computer Humor

Craig Maloney will be running a session discussing computer humor throughout the ages. We’ll touch on older topics like the BOFH and the Jargon File, as well as more current-day sites like XKCD and the Daily WTF.

And we’ll also have our normal MUG meeting features: Jobs Looking For People, People Looking for Jobs, news and events, and much much more.
