The next ALE-NW@SPSU meeting is being held
Thursday, Feb. 9th, 2012 at 7:30pm in room J131
of the Atrium (J) building on the SPSU campus.
The feature presentation will be
Seat Belts and Airbags for Bash
with Michael Potter
- bash (and scripting languages in general) act as the glue that hold other
system components together. This presentation will focus on the underutilized
features of bash that are critical to building production quality scripts, Demos
will show you how to turn on options that expose the hidden timebombs in
- Turning these features on should be considered a requirement much like
turning on strict and warnings are considered a requirement for Perl.
- Much of the bash syntax is redundant; I will also explain which syntax to
use and which syntax to avoid.
- Knowledge of any of the common UNIX scripting languages will be sufficient
to attend this meeting. Scripters at all proficiency levels will get value from
attending this presentation. Although I do not address differences between
Korn shell and bash, much of what I talk about also applies to Korn shell.
- I developed this presentation after getting frustrated with bash’s default
behavior of continuing to process after an error occurred. I was determined
to find a way to make bash a more reliable language.
- Michael has been working in IT since 1989 when he switched from
programming automotive embedded systems. Since that time he has
been involved in projects related to moving mainframe applications to
UNIX and Linux using open-source technologies.
- Recently Michael incorporated Tapp Solutions, LLC. A company
dedicated to serving the insurance industry with mobile, desktop and
web applications. Including handheld quote calculators and scanned

Our featured presentation will be a reprise of the popular
talk offered at the Jan. 12 meeting of ALE-NW@SPSU:
Network and Systems Management
presented by Jeff Gehlbach
– Whether your organization’s network has a dozen nodes or twelve-thousand, it
sucks when some of those nodes go down or have performance problems. A whole
discipline of network and systems management has evolved to deal with this
problem, resulting in many software platforms both free and proprietary aiming
to solve it. One of these, OpenNMS (Open Network Management System), brings a
100% free and Open Source software approach with massive scalability as its key
operational goal. This talk will present a gentle introduction to network
management concepts along with a tour of OpenNMS’ architecture and, provided the
stars align, a live demo!
– Jeff Gehlbach discovered Linux in 1994 when a friend shared with him a box
of floppies containing Slackware 2.3, and has been hooked ever since. He has
subsequently worked as a network engineer, Solaris and Linux systems admin,
network management consultant, and network management software developer
among others. Today he pays the bills by helping organizations manage their
networks and systems using free software including OpenNMS.
Our ALE Central meetings are usually held at Emory
