Internet Changes/Linux Changes
Both Linux and the Internet are growing—in size and in maturity. This month the Internet took a big step toward maturity compliments of the U.S. Supreme Court. I'm talking about the Communications Decency Act.
At issue was an overhaul of telecommunications regulation that included a section restricting the distribution of indecent or “patently offensive” material to minors over the Internet. While this restriction may sound reasonable to people less involved in the Internet than your average Linux user, I think we all know that attempting to legislate control over something with no central control, such as the Internet, doesn't work. If there were central control, the Internet itself couldn't work.
In what seems to be a well informed decision, the court said that the Internet deserved full First Amendment protection, pointing out that it was unique as a public forum for the exchange of ideas and information. They rejected the argument that the Internet is similar to television and radio industries. The difference, obvious to Internet users, is that while information is pushed at you on television, you seek information on the Internet.
Justice Stevens said “The [Communications Decency Act] is a content-based regulation of speech,” and went on to say, “The vagueness of such a regulation raises special First Amendment concerns because of its obvious chilling effect on free speech”.
At the same time, Linux is maturing in a very good way. First, CD distributions for the PowerPC are finally starting to appear. In June, the Linux for PowerPC project announced another release that supports hardware from Be Inc, Apple Computer, IBM, Motorola and most any other manufacturer of PowerPC computers.
The PowerPC is distinct from the MkLinux port for PowerMacs. MkLinux is based on the Mach microkernel. This project is based on a port of the standard Linux kernel. More information is available at http://www.linuxppc.org.
Another way Linux is showing its maturity is by addressing the usefulness of any computer system to people with disabilities. One organization that is involved in this effort is the Center for Disabled Student Services at the University of Utah. They offer a mailing list and pointers to pages that offer access information. You can find their web page at http://ssv1.union.utah.edu/linux-access/.
I wasn't surprised to find software addressing use of Linux systems by the blind including information on efforts to make documentation on Linux available text to speech and text to braille software. There is also a tips page on accessible web page design and even a list of hardware and software for the blind.
Here at LJ we have had inquiries over the years about printing the magazine in braille. This has never been practical because of the volumes involved. To address this we have made parts of the magazine available on-line and also have plans for a back issues CD. It is great to see that there are Linux-based options based on Linux for the blind to access this information.
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
