Cloud Computing Expo
Last year a client asked us for advice on getting started with programming.
So I thought I’d share some thoughts about programming, its relationship
with FOSS (Free and Open Source Software) management and why Python is a good
language for learning programming including some great on-line resources. But
first I want to make sure our business-oriented readers understand the nature
and importance of source code.

The “source” aka “the code” provides a language in which computer
users can create or change software. One does not have to be a programmer to
work on the code. In fact, every computer user is, ipso facto, a programmer!
Menus, web interfaces, and graphical user interfaces (GUIs) are some of the
more facile “languages” for computer programming that everyone, even
children, ... (more)
I will be attending the 5th Annual Emerging Technologies for the Enterprise
Conference (ETE 2010) this Thursday and Friday, April 8-9, 2010.
The event is billed for “developers, architects, and IT executives” and
attempts to provide a dynamic forum for “emerging technology and Open
I look forward to seeing Robert C. (Uncle Bob) Martin’s keynote on “Bad
Code, Craftsmanship, Engineering, and Certification”, a panel discussion on
“Open source is a commercial enterprise”, another panel on “Social
Media: Why should I care?”, a second Bob Martin presentation on “Agility

In January I attended the 10th annual Southern California Linux Expo. In
addition to speaking and running the Ubuntu booth, I had an opportunity to
talk to other sysadmins about everything from selection of distribution to
the latest in configuration management tools and virtualization technology.
I ended up in a conversation with a fellow sysadmin who was using a
proprietary virtualization technology on Red Hat Enterprise Linux. Not only
did he have surprising misconceptions about the FOSS (Free and Open Source
Software) virtualization tools available, he assumed that some of the... (more)

The November 2009 issue of Communications of the ACM (CACM) has a very
interesting article by Paul Stachour and David Collier-Brown entitled “You
Don’t Know Jack About Software Maintenance”. The authors argue
energetically for using versioned data structures and “continuous
upgrading” to improve the state of the art of software maintenance.
The piece got me thinking about FOSS (Free and Open Source Software) and
“continuous upgrading”. Here are seven observations on FOSS software
maintenance that occurred to me as I reflected on the CACM article:
Although I haven’t seen a thoroughly researched study, I figure there must
be at least 250,000 FOSS (Free and Open Source Software) tools available to
every systems administrator on the planet (230,000 at SourceForge + 15,000 at
Launchpad + 12,000 at CodePlex + 5,000 at Google Code and that doesn’t
count the Linux kernel or any of the myriad other self-hosted projects).
These 250,000+ resources comprise the full “toolbox” that admins can use
for building solutions with FOSS; they represent the FOSS equivalent of COTS
(Commercial Off-The-Shelf). Of course, if you add open source b... (more)
