Standing Up to Hurricane Ike. . . with Linux, of Course
As some of us at Linux Journal clean our yards of debris, repair our broken windows, and make do with spotty internet access, power outages, and grocery shortages, we thought we'd share a story about the silver lining in the reality that is big, bad hurricane Ike.
All of us at Linux Journal's Houston office are just fine, and we have found ways to stay in touch with each other and our community. We have used whatever technology is available to us to exchange information and coordinate our efforts. Tools like SMS messaging, twitter, and web-enabled phones make post-hurricane clean-up and efforts to return to normal so much easier than they have ever been in the past.
One online hub of information has proven essential to Houstonians and the rest of the world to stay informed about evacuations, power restoration procedures, photo galleries detailing damage, and much more related to getting past a disaster of this magnitude. Our local newspaper, the Houston Chronicle, has a pretty fantastic online edition that has handled this all gracefully, and kept us all as sane as possible during the whole ordeal. Those few of us with power, combined with mobile users and many millions of eyes from around the world have descended on Chron.com and increased their traffic almost six-fold, but the site has not even experienced a hiccup. We have friends over at "the Chron," and we'd like to give them a huge shout-out for their efforts.
I spoke with Steven Evatt who is responsible for the Linux servers that keep Chron.com up and running, and their story is truly impressive. Steven stayed at "the bunker" north of town to make sure the site stayed up throughout the storm, and the rest of the available staff who were not flooded-in reported to work as soon as the storm passed to make sure the site was constantly up and updated with essential information.
Chron.com expects to hit 17 million page views today, up from their usual 3-4 million, and their use of open source technology is a big part of that. Steven Evatt believes "open source technology has allowed them to rapidly scale," and all of this with the "skeleton crew" that was available to report to work. As a result, the site has been available to many extra users without consequence, which is not typically the case with local media during such a disaster.
We want to congratulate these guys on weathering the storm so gracefully.
In the meantime, Linux Journal is still business as usual, though we may be out of the office for a few days. Thanks for all the well-wishes!
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
