On the Web - Make the Most of Your Summer
The sun is out, the temperature is steadily rising, pale legs find themselves thrust into the glare of day and multiplexes are showing 12 screens' worth of sequels—must be summer. Remember being a kid, when summer meant doing things you never had the time to do when school was in session? These days, few of us have the luxury of summers off, but that doesn't mean we can't do something adventurous this August. So stop mourning Buffy, quit complaining about Reloaded and do something you've wanted to do but didn't have the time for: build your own workstation, put a Linux installation on your laptop that actually works, transform a spare computer into a server. And to help you with these projects, the Linux Journal web site offers the following articles and tutorials.
First off, if you've been following Jay Docherty's Linux on the laptop series, he wrapped it up with “Polishing Your Linux Laptop Setup” (www.linuxjournal.com/article/6891). This article discusses how to go wireless, how to install ALSA sound support and how to set up the ACPI power management component. Jay admits “ACPI can be a beast to set up”, but it can reduce the clock speed when the laptop is idle to increase battery life and control the system's fans for thermal protection. All in all, if you're wanting to put Linux on your laptop, Jay's complete series is worth a read.
In “High Availability Linux with Software RAID” (www.linuxjournal.com/article/6412), Micah Silverman describes how he recycled a system to create an HA server. He explains how to use “software RAID Level 5 under a fresh installation of Red Hat 8.0” and how to test the fault tolerance of the RAID. Before going live with this setup, Micah built a testbed by using VMware “to set up a Linux virtual machine with six 9GB SCSI drives...on a machine with only one real physical IDE drive”.
If you've been wanting to build your dream Linux machine, you might want to check out Glenn Stone's weekly articles about the components he's thinking of including in this year's Ultimate Linux Box. “Getting Serial: the Ultimate Linux Box S-ATA Disk Subsystem” (www.linuxjournal.com/article/6902) weighs the benefits of using serial ATA drivers against their higher cost compared to traditional ATA controllers. Specifically, Glenn discusses the performance of 3ware's 8500-4 serial ATA card. When used in our testbed machine, Glenn found that serial ATA offers “some fairly serious bang” for not too many more bucks. Glenn has also been thinking about what sort of video card the “Ultimate” machine should have (“Some Graphic Remarks: VGA for the Ultimate Linux Box”, www.linuxjournal.com/article/6922). To that end, ATI's new Fire GL X1 workstation card may be just the card to get us closer to the dream. This card has dual DVI-I digital/analog outputs that each have a DVI-to-VGA adapter, so you can use a standard monitor instead of a digital one.
These are only a few of the projects you can take on with the help of the Linux Journal web site. Search the site for other ideas; new projects are posted every week. If you'd like to share your own project, send the proposal to 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
