Perceptions of the Linux OS Among Undergraduate System Administrators
There's not much to say by way of commentary here, as these statements speak for themselves.
Clanger #1: “Linux will never threaten Windows on the desktop because it is command line driven and doesn't even have a GUI”. What can I say?
Clanger #2: “Linux has poor device-driver support and doesn't even support USB”. Not so, officially, as of the 2.4 kernel (regarding USB). And driver support with Linux gets better every single day.
Clanger #3: “Linux lacks good software development tools, unlike Windows which has plenty.” It's hard to comment on this without imagining the good folk at the Free Software Foundation blowing their collective tops at the very idea that someone could think (let alone say or print) such a thing. Also, despite the fact that Visual C++ is the “industry leader” when it comes to C++ development on PCs, my experience with final year software engineering undergraduates indicates that Visual C++ is a dog of an environment to work with.
And the final clanger was that many of my students thought Linux was a company!
Now, I'm the first to admit that my informal survey of these 31 students may be flawed (from a statistical sampling point-of-view). However, I'd bet that the views and opinions expressed by my students are typical and representative. My original goal in setting the assignment was realized: my students now have a better understanding and appreciation of what Linux is.
Of course, I was shocked by some of the views of my students. However, on reflection, I'm not surprised that some of the views were voiced. Microsoft can afford to throw a lot of money into its “Linux Myth Campaign”. And, as everyone knows, if you throw enough of something, some of it is bound to stick. Education is a, if not the, key defense mechanism.
And, what about my own view? I feel that although Linux may never threaten Windows as a desktop OS, increasingly it is becoming a viable alternative.

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
