Ladies and Gentlemen, Our Flight Has Been Hacked
It's possible to hack just about anything — even the occasional toaster — but according to FAA documents, it's even possible to hack Boeing's new 787.
The documents — known as "special conditions," and utilized whenever there aren't existing regulations to cover a given issue — reveal the FAA's concern that the systems designed to provide in-flight internet access to passengers are tied into the systems that navigate, control, and provide communication for the plane. While the document's language makes the issue seem dire, Boeing representatives claim the system is not really as connected as the FAA seems to think, though they did admit "there are places where they [the networks] are [touching]." They went on to say that Boeing has been working on the issue with the FAA for a number of years, and that the issue will be resolved before the planes go into service, currently anticipated for November 2008.
Still, I know if I'm ever on a 787, I'll be just a little bit nervous that we might end up in Timbuktu, hacked by Little Timmy in seat 25B.

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
