Focus: The Internet
The Internet is taking over our lives—talk about world domination; it has won. Advertisements on TV, billboards, essentially anywhere, all carry the familiar www.dot.com. It has become de rigueur for a business to have its own web site. And customers are finding these sites and using them. I buy DVDs, flowers and cards on the Internet; a co-worker buys her groceries there; another does all his gift shopping. The day may come when department and grocery stores are no longer needed, and it might not be very far off.
Statistics show that maybe 30% of U.S. households have computers with access to the Net. This is going to go up rapidly in the next few years as Internet appliances—computers for the computer-illiterate—come to the market. These book-size computers will offer Internet connectivity, and not much more. They will be as easy to use as a VCR. People who never thought about buying a computer before will buy one to find out why everyone is talking about and using the Web. Then they will be hooked too—just like the rest of us.
A company that is betting on this is OE/ONE, and I talked to Mr. Eid Eid about his new start-up and the innovative software they are building for this potentially lucrative appliance market. Mr. Eid is a very personable and forward-thinking man with some interesting ideas about how the Internet will be used in the future.
Quality of Service support in the kernel has created a new controversy for our community. ISPs now have a way to control traffic so that those who pay more can have priority over those who don't, getting faster connections and faster response times to problems. Linus created Linux and gave it to the community through the Internet. Programmers develop code and share it through the Internet. Without the Internet, Linux would not exist. The Internet has always been a place where all are equal. There is now the possibility that will not always be true.

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
