As announced in our Cluster Services Built With FOSS post, LinuxForce’s
Cluster Services are built exclusively with Free and Open Source Software
(FOSS). Here is an expanded outline of the basic architecture of our approach
to High-Availability (HA) clustering.
In any HA deployment there are two main components: hosts and guests. The
hosts are the systems which are the core of the cluster itself. The host runs
with very limited services dedicated for the use and functioning of the
cluster. The host systems handle resource allocation, from persistent storage
to RAM to the number of CPUs each guest gets. The host machines give an
“outside” look at guest performance and give the opportunity to
manipulate them from outside the guest operating system. This offers
significant advantages when there are boot or other failures which
traditionally would require phys... (more)

Last weekend I had the pleasure of presenting at the Central Pennsylvania
Open Source Conference on the topic of Contributing to FOSS (slides available
In the talk I explored the many ways individuals can get involved in FOSS
(Free and Open Source Software), briefly covering everything from programming
to artwork to documentation. As diverse as these contributions are, the
common thread is close collaboration with the project itself. In particular,
following the procedures in place for contributing to the project is
essential. The talk also reviewed some... (more)

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.

On Saturday, May 7th, I’ll be taking a flight out to Budapest, Hungary to
attend the week-long Ubuntu Developer Summit (UDS) as the kick-off event to
the development of the next Ubuntu release, 11.10 (code name Oneiric Ocelot)
coming out in October 2011.
The Ubuntu Developer Summit is the seminal Ubuntu event in which we define
the focus and plans for our up-coming version of Ubuntu. The event pulls
together Canonical engineers, community members, partners, ISVs, upstreams
and more into an environment focused on discussion and planning.
My role at these summits as an Ubuntu Commu... (more)
