This article describes the HA-OSCAR architecture and features, and
demonstrates how to set up a highly available Linux cluster using the first
beta release of HA-OSCAR version 1.0.
In 2002, Ibrahim Haddad, Chokchai Leangsuksun, and Stephen L. Scott
established the HA-OSCAR (High Availability OSCAR) project with a primary
goal of leveraging the existing OSCAR (Open Source Cluster Application
Resources) technology while providing high-availability and scalability
capabilities for Linux clusters. The OCG (Open Cluster Group) recognized the
project as an official working group, along with the current OSCAR and
Thin-OSCAR (diskless cluster) working groups.
The anticipated users of the HA-OSCAR technology are members of the
telecommunications industry and other industries looking to deploy highly
available Linux-based clusters such as ISPs, ASPs, and HPC site... (more)
Firefox and Thunderbird are Open Source products that are made available by
the Mozilla Foundation. Open Source development lets anyone who wants to to
examine the source code, or if they wish, to modify it. There are a number of
advantages to Open Source development, including the fact that many people
look at the code every day, which results in better responsiveness as bugs
are uncovered. This dynamic development community is able to provide
continual feedback to make the product better, paving the way for a better
browsing and e-mail experience for everyone.

This article provides an update of the Carrier Grade Linux initiative, the
CGL specification, distributions, platforms and deployments.
Carrier Grade Linux - The OSDL Initiative
The OSDL Carrier Grade Linux working group was established in January 2002.
Its goal is to identify requirements for enhancing the Linux operating system
to achieve an open source platform that is highly available, reliable, secure
and scalable, and so suitable for carrier grade systems. The CGL working
group has the vision that next-generation and multimedia communication
services can be delivered using L... (more)
Robert C. Seacord, a senior vulnerability analyst at the CERT/Coordination
Center at Carnegie Mellon University, has just published the book Secure
Coding in C and C++ (Addison-Wesley, 2005). I sat down with him to discuss
software security in the Linux environment and elsewhere.
LWM: There's an ongoing debate over whether Linux is more secure than
Windows. Some people argue that since Linux's source code is freely
available, it makes it easy for hackers to implement hacks and break into
Linux systems, whereas this becomes more difficult with proprietary operating
systems. What'... (more)
The open source development model has unique characteristics that make it in
some instances a superior model for developing software compared to the
traditional software engineering cascade model. As with other practices, the
open source development model had its advantages and inconveniences. Will
adopting the open source development model improve the way your corporate
developers work and produce software? What are the best practices from the
open source development model that we can use in a corporate environment?
The open source software development model has a different proce... (more)
