I'm a regular reader of your magazine here in the UK. I would really like to see a good, well-researched story on IP SANs, iSCSI and Linux. I've been noticing lots of activities in this area, and it looks like Linux is playing a big role in this. I got involved in the subject because I'm on a committee that should (supposedly) decide on network storage strategies at our place (News International, big corporation). There are a couple of small companies already offering iSCSI targets, and all of them appear to be Linux-based. See for instance www.pyxtechnologies.com (this is Andre Hedrick) or technomagesinc.com. The subject is pretty hairy. If you want more information or links, let me know.

I saw, in the September 2002 issue of LJ [“What Has 1.1 Terabytes, 9,503 BogoMips and Flies?”], a project system that listed the CPU performance in BogoMips. What is a BogoMip, and how is it measured?
BogoMips are a measurement of how fast the kernel runs a simple delay loop. See the BogoMips Mini-HOWTO at www.tldp.org/HOWTO/mini/BogoMips.html.
What font are you now using in the headlines on the cover of your magazine? I know this is a strange question, but I rather like that font, and being a graphic designer, I would like to use it.
Lydia Kinata replies: We use the DaxWide font family on the cover and for article titles and headers within the magazine. DaxWide comes in several weights, from very light to “Extra Black”. It's a very useful font.
I read your article on secure PHP applications in Linux Journal, October 2002, and I thought it was quite useful. An additional source of information on the subject is the “The OWASP Guide to Building Secure Web Applications and Web Services” (www.owasp.org/guide). A lot of “good practices” are combined in a single document.
I know some people think the “battle” between Linux and Microsoft is a religious quest, but the letter from Renato Carrara is just plain silly. [See the “Don't Run Microsoft Ads” letter in LJ, November 2002]. A magazine is a business proposition, and ads pay for the magazine. As long as they don't flagrantly violate good taste, magazines should run whatever ads are proffered. Microsoft is probably astute enough to understand it would not find a receptive market here.

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
