Ultimate Linux Box 2005
Cases capable of accommodating and doing justice to Ultimate Linux Boxes are rare. This year, only one alternative would work: going full custom. This year's case has acrylic windows to show off the cooling system, integrated supports for the three Reserators and a mounting place for the RME Multiface.
Difficult as it might be for us to believe right now, many real-world systems don't need both 52-channel audio and Fibre Channel. But unusual combinations of hardware are what enable creative projects, and we're happy that Linux stays out of our way and lets us hook up what we want.
When you start with what's possible and take out what you don't need, you'll be confident that you can build a machine for your needs. We hope that whatever class of system you decide to build, you'll get some ideas out of this year's Ultimate Linux Box.

Hardware of the Future, Lawyers Stuck in the Past
It never fails. New products that we'd like to try in the Ultimate Linux Box come out right when we're in the middle of building this year's.
Too late to make it through our thermal testing, AMD introduced dual-core Opteron processors, which let you build an eight-way system on an existing four-socket motherboard with a BIOS upgrade. Today, that means spending $10,000 on processors, but (all together now) we expect prices to come down.
We're watching the progress of the LinuxBIOS Project (see page XX) and are planning to get a supported motherboard for next year. We know patience is a virtue, but booting in mere seconds is cool for its own sake.
This year's system sounded so nice that we'd like to do another quiet machine next year. That means we have to pick a storage technology, and added to next year's list of alternatives will be ATA over Ethernet, as covered in Ed Cashin's article in the June 2005 issue.
Video is still a weak spot, not because of hardware problems, but because of the vendors' lawyers. Everybody doing 3-D is infringing everyone else's patents, and burying the driver code behind a proprietary EULA with a no-reverse-engineering clause is only slowing the industry down. When the normal kernel development process frequently breaks the driver for commonly used hardware, that hardware needs to get with the program.
Graphics vendors, please get together, cross-license the patents for hardware, and come up with a license for software and documentation that lets developers release the new code that makes people want graphics hardware in the first place. It'll help everyone in the long run—NVIDIA maintains an entire parallel software distribution system just because of its licensing decision. Why not get that cost center out of the budget?
Pessimists will say to be “realistic” and accept the proprietary drivers. But realistically, the UNIX vendors of the mid-1990s weren't about to support Linux, either. Today, every UNIX vendor is out of business or supporting Linux. I'll put reality up against “realistic” any day.
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
