Linux In The Real World: Linux Serving IKEA
Today, system size has increased to well over 700 IP hosts due to the fact that new LANs with networked NT servers and Windows PCs are popping up every day of the week. How have CYGNUS and his partner (yes, it's a he) coped with this? Until today, there has been no problem worth mentioning (aside from a total power outage which killed both systems). Oh yes: one big problem is to make people not used to Unix use RCS and vi to manage our DNS files.
Another problem with Linux is that it's too cheap. I'm serious, since many people still put an equal sign between Cheap/Free and Bad/Dangerous. In the case of Linux (and XFree86) this has proven to be pure nonsense.
There are some companies here in Sweden offering support for Linux. I think that this will help to make Linux more socially acceptable; if you find somebody who is willing to accept a check from you, then you can always shout and yell at him if there are unsolved problems. Personally, I prefer to have direct contact with the programmers and designers.
A year later, that system is still running Linux 1.0 and UUCP. There have been a few problems, all caused by the other UUCP partner (I won't mention any brands), but all-in-all, everybody was happy. So happy, in fact, that a few of our techies have also tried Linux out on their own PCs. Some, like me, have kept Linux for good.
Anders Östling is a die-hard VMS fan who, after spending 10 years in the Digital farm, has gotten more and more into Unix and networking. When not doing what he's paid for—managing computers and networks—he likes to cuddle with his kids, computers, pets and wife (in no particular order...). He lives in the countryside outside Helsingborg in an old miner's village called Gunnarstorp. Don't miss it when you are in Sweden! If you have any questions or comments (general or DNS), he can be reached at email@example.com.
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
