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)
Open Source Journal on Ulitzer
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)
Last week I read a good article on cloud computing, Cloud ROI: A Grounded
View. It seems that even with all the hype (or because of it?) most are not
“running blindly” to adopt “the cloud”. I must admit the cloud
metaphor has a powerful poetic charm to it.
That is probably why it has grabbed the attention of so many over the past
few years. Everything in our world is ephemeral, so there is an aptness to
the concept of a “cloud”. Moreover, I too like and use cloud analogies.
But I am now looking for clearer skies!
Here is a short list of my gripes about "the cloud":

Federal Computer Week published a great, succinct quote from Richard
Schaeffer Jr., the NSA’s (National Security Agency) information assurance
director, on three approaches that are effective in protecting systems from
We believe that if one institutes best practices, proper configurations
[and] good network monitoring that a system ought to be able to
withstand about 80 percent of the commonly known attack mechanisms
against systems today, Schaeffer said in his testimony. You can
actually harden your network environment to raise the bar such that
the adversary has to ... (more)
