Linux in Kuala Lumpur
Linux came in handy for providing lab sessions in the senior-level course ECE4330 VLSI Design. This course would have gone without any true labs, as the commercial VLSI (very large scale integration) layout tools are too expensive for us. I set up the MAGIC VLSI layout editor under X and supplemented it with SPICE (simulations program with integrated circuits emphasis) for small layout simulation and verification. As there is no licensing problem, students could use these tools simultaneously on several workstations.
After coming across articles in the January 1998 LJ about PVM (parallel virtual machine), I set up the PVM web course server on one of the Linux machines. I divided the students into several groups and allocated two Linux machines to each group. Their target was to set up one machine as the master and the other as the slave in a PVM environment, then test various programs. Although the students could not succeed fully in running various programs, they enjoyed working on such important concepts with full control over the computers.
My current projects include setting up a filtering firewall using Red Hat Linux and binding an HP workstation cluster to the Linux NIS server for user account authentication. Thus, we will be able to stop some wasteful use of the Internet, as well as provide centralized accounts for all UNIX users.
Practical Task Scheduling Deployment

One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
