Hackers Try to Suck the Earth Into Black Hole
If there weren't already enough problems at the European Organization for Nuclear Research — angry calls & letters, protests, panic, even death threats — surrounding the Large Hadron Collider — in addition, that is, to the chief problem of making the device work — there certainly are now, as a new and particularly frightening problem has arisen: hackers.
One might presume that the LHC would be a pretty hard target to hit. After all, it's being run by an international coalition, security is already on high alert due to the frenzy surrounding the possibility of sparking Armageddon, and, of course, it runs Linux. None of that seems to have deterred a group of hackers calling themselves the "Geek Security Team," as the group managed to hack the machine last Wednesday as the first beams were circulating. The hackers gained access to one of the computer systems operating the Compact Muon Solenoid Experiment, a massive magnet that serves as one of the detectors analyzing the LHC's activities, and modified a web page with a message in Greek ending ""We are 2600 - dont [sic] mess with us."
According to scientists, had they penetrated one level further, they would have gained sufficient access to turn off parts of the CMS detector. We don't know about anyone else, but it worries us just a tad that: a) hackers got into this thing, b) that the scientists who told us the LHC wouldn't suck us all into a black hole didn't know it could be hacked, and c) that the end of the world could be the result of restless script kiddies. We always thought it'd be the Vogons.

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
