UnixWare and Linux Get Hitched
Remember Xenix? That is what Microsoft called their UNIX-derived OS, before they pawned the PC version off on Santa Cruz Operation (SCO) in 1984. SCO, which had its own version of UNIX, also bought UnixWare from Novell in late 1995. UnixWare was Novell's name for the original AT&T UNIX, which Novell bought a couple years earlier for more than $100 million in Novell stock.
Some Novell engineers who worked on UnixWare are currently at Caldera. And now they're getting it back. In early August, Caldera acquired the Server Software and Professional Services divisions of SCO. This now gives Caldera several kinds of UNIX to sell (including Linux and UnixWare), while SCO gets a 28 percent stake in Caldera in the form of 17.5 million shares of Caldera stock.
How things have changed. In 1996, SCO sent spam faxes telling people they could get a $50 trade-in on their copy of Linux by upgrading to SCO UNIX. In October 1996, I asked Bryan Sparks, then CEO of Caldera, about SCO. Specifically, I asked whether Caldera would have a market if SCO had embraced Linux. At the time, SCO was very big in the OEM/VAR market, which was where Caldera was headed. Bryan agreed with my theory, pointing out that many of Caldera's IVPs (Independent Vendor Partners) were from the SCO camp. (That interview was published in the January 1997 issue of Linux Journal.) Now those camps will be in one company: Caldera.
This is good for Linux. With one company offering a choice—UNIX or Linux—the customer has to take the most useful and market-ready alternative. Those of us who have been around for a while know that in most cases, Linux outperforms SCO UNIX. But making that choice isn't a no-brainer for companies that also have to switch vendors and support organizations. Caldera's SCO acquisition takes care of that problem.
Having UNIX and Linux coming from the same company will also make it much easier to get applications written, ported and supported in both environments. SCO's huge existing support structure is a big win here.
Finally, SCO, Sequent and IBM have been working together on the Monterey project, which aims to deliver a single UNIX product line spanning the Intel IA-32, IA-64 and Power PC platforms. Having all this cooperation under one roof—a Linux-based roof—is going to make it much easier to go head-to-head with NT for server solutions. Given a mix of Apache's current market penetration (62.53%, according to Netcraft), SCO's global marketing and support infrastructure and Linux, Caldera should give Microsoft a run for its money in the server and e-business arena.
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
