Red Hat Linux 5.0

TheNextLevel is an excellent front end to X, offering much the same look and feel as Windows 95 and NT 4.0. The Red Hat 5.0 release of TheNextLevel is much closer to the look and feel of Windows 95; in particular, the “feature” of having to click to gain keyboard focus is enabled by default now, so first-time Linux users feel more at home.
Red Hat has announced a set of support plans and partnerships that should make Linux more acceptable in the corporate world. Also, Linux's distributed support model has recently won awards from Infoworld and other magazines for “Best Technical Support”.
Over the course of these upgrades I did a number of things that are difficult, expensive or impossible to do with NT or Windows 95. Immediately after the base install was complete, I was able to exit the computer room. From the comfort of my own office, I completed the upgrades, added additional software, etc. From the comfort of my home, through two firewalls, I initiated a remote backup, did an A/B comparison of the new features of Red Hat via X in an ssh tunnel, wrote this review and installed, configured or updated even more of the Linux software. UNIX's enormous advantage in the remote administration area will probably continue into the age of high speed Internet access in the home.
Red Hat 5.0 is a solid core Linux distribution with a sharp eye out for the future. The new Glibc library implies a little risk and breaks some backward compatibility—expect to update this library a lot over the coming months as new bugs are found and fixed—however, the additional features are worth it. The future for both Red Hat and Linux looks very exciting—with the rapidly advancing KDE and GNOME/Enlightenment desktops and the release of Netscape source code.
But it's not all clover. During the installation, configuration and upgrade process there remain many problems which stopped two otherwise enthusiastic first time users and had me stumped more than once.
Due to the large number of patches and upgrades already required, I'm going to wait for 5.1 to put this release onto the rest of my production machines. I'm very concerned about potential security holes in Glibc. Red Hat 5.0 is an evolutionary release. Sometimes you have to take a step backward to take two steps forward. Red Hat 4.2 is a more mature, easier to use distribution than Red Hat 5.0. At this point I'd recommend 5.0 only to developers.
Red Hat is freely available from the Internet and in a commercial release that costs $49.95 US. It is also available bundled with books, manuals and/or applications.

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
