Moving Away From the IT Field? 783

Posted by kdawson from the life-on-the-other-side dept.
irving47 writes 'With the economy the way it is, it's a little iffy to even think about switching careers completely, but lately, I've gotten more and more fed up with trying to keep up with the technical demands of companies and customers that are financially and even verbally unappreciative. While I might be good at it, and the money is adequate, I'm curious to hear from Slashdotters who have gone cold-turkey from their IT/Networking careers to something once foreign to them. How did you deal with the income difference, if any? Do you find yourself dealing with people more, and if so, how did that work out?'

The US's Reverse Brain Drain 757

Posted by kdawson from the laugha-while-you-cana-monkey-boy dept.
We may have to rethink the assumption that Silicon Valley is the hotbed of innovation in which all the world's best and brightest want to work and live. TechCrunch has a piece by an invited expert on the reverse brain drain already evident and growing in the US as Indian, Chinese, and European students and workers in the US plan to return home, or already have. From an extensive interview with Chinese and Indian workers who had already left: "We learned that these workers returned in their prime: the average age of the Indian returnees was 30 and the Chinese was 33. They were really well educated: 51% of the Chinese held masters degrees and 41% had PhDs. Among Indians, 66% held a masters and 12% had PhDs. These degrees were mostly in management, technology, and science. ... What propelled them to return home? Some 84% of the Chinese and 69% of the Indians cited professional opportunities. And while they make less money in absolute terms at home, most said their salaries brought a 'better quality of life' than what they had in the US. ... A return ticket home also put their career on steroids. About 10% of the Indians polled had held senior management jobs in the US. That number rose to 44% after they returned home. Among the Chinese, the number rose from 9% in the US to 36% in China."

Michael Dell Says Windows 7 Will Make You Love PCs 627

Posted by samzenpus from the most-improved-OS-award dept.
ruphus13 writes "In a recent talk at the Churchill Club, Michael Dell addressed several topics, including the fact that Windows 7 is poised to take advantage of the upgrade cycle. Dell has always been a strong MS OEM ally and it is now hoping to cash in again from the impending upgrades. From the post: 'Dell made plain several times that he sees the installed base of technology as very old, and sees a coming "refresh cycle" for which he has high hopes. "The latest generation of chips from Intel is strong, particularly Nehalem," he said, adding, "and Windows 7 is on its way." (The operating system arrives Oct. 22nd, although Microsoft's large-volume licensees are already getting it.) He pointed out that many business are running Windows XP, which is eight years old. "I've been using Windows 7 for a long time now," he said, "and if you get the latest processor technology and Office 2010 with it, you will love your PC again. It's a dramatic improvement."'"

The Ultimate Limit of Moore's Law 418

Posted by kdawson from the double-double dept.
BuzzSkyline writes "Physicists have found that there is an ultimate limit to the speed of calculations, regardless of any improvements in technology. According to the researchers who found the computation limit, the bound 'poses an absolute law of nature, just like the speed of light.' While many experts expect technological limits to kick in eventually, engineers always seem to find ways around such roadblocks. If the physicists are right, though, no technology could ever beat the ultimate limit they've calculated — which is about 10^16 times faster than today's fastest machines. At the current Moore's Law pace, computational speeds will hit the wall in 75 to 80 years. A paper describing the analysis, which relies on thermodynamics, quantum mechanics, and information theory, appeared in a recent issue of Physical Review Letters (abstract here)."

Entire .SE TLD Drops Off the Internet 207

Posted by timothy from the absolut-typo dept.
Icemaann writes "Pingdom and Network World are reporting that the SE tld dropped off the internet yesterday due to a bug in the script that generates the SE zone file. The SE tld has close to one million domains that all went down due to missing the trailing dot in the SE zone file. Some caching nameservers may still be returning invalid DNS responses for 24 hours."

Has the Glory Gone Out of Working In IT? 623

Posted by ScuttleMonkey from the good-old-days dept.
An anonymous reader writes to wonder if the glory has gone out of IT. One blogger remembered his first impression upon entering a profession in IT that made it seem like the place to be, with a new shiny around every corner. What experiences have others had? Has a more pervasive technical culture forced our IT gurus into obsolescence?

Scientists Find Master Gene To Switch On Immune Cells 94

Posted by ScuttleMonkey from the nature's-lightswitch dept.
Scientists claim to have identified a master gene which is able to transform blood stem cells into disease-fighting immune cells. The hope is that this discovery will allow for new treatments for cancer. "The researchers have 'knocked out' the gene in question, known as E4bp4, in a mouse model, creating the world's first animal model entirely lacking NK cells, but with all other blood cells and immune cells intact. This breakthrough model should help solve the mystery of the role that Natural Killer cells play in autoimmune diseases, such as diabetes and multiple sclerosis. Some scientists think that these diseases are caused by malfunctioning NK cells that turn on the body and attack healthy cells, causing disease instead of fighting it. Clarifying NK cells' role could lead to new ways of treating these conditions."

Why Motivation Is Key For Artificial Intelligence 482

Posted by Soulskill from the i-have-no-mouth-and-i-must-scream dept.
Al writes "MIT neuroscientist Ed Boyden has a column discussing the potential dangers of building super-intelligent machines without building in some sort of motivation or drive. Boyden warns that a very clever AI without a sense of purpose might very well 'realize the impermanence of everything, calculate that the sun will burn out in a few billion years, and decide to play video games for the remainder of its existence.' He also notes that the complexity and uncertainty of the universe could easily overwhelm the decision-making process of this intelligence — a problem that many humans also struggle with. Boyden will give a talk on the subject at the forthcoming Singularity Summit."

Making Sense of Revision-Control Systems 268

Posted by kdawson from the only-constant-is-change dept.
ChelleChelle writes "During the past half-decade there has been an explosion of creativity in revision-control software, complicating the task of determining which tool to use to track and manage the complexity of a project as it evolves. Today, leaders of teams are faced with a bewildering array of choices ranging from Subversion to the more popular Git and Mercurial. It is important to keep in mind that whether distributed or centralized, all revision-control systems come with a complicated set of trade-offs. Each tool emphasizes a distinct approach to working and collaboration, which in turn influences how the team works. This article outlines how to go about finding the best match between tool and team."

One counterexample to your point is worth mentioning: Startups driven by ex-academics. There are case studies of successful ventures where researchers came out of the university and into the private sector to apply research to commercial problems. They are niche, but perhaps that's how you could clarify your assertion - by also mentioned niche solutions based on solid research.

Alan Cox Quits As Linux TTY Maintainer — "I've Had Enough" 909

Posted by timothy from the when-smart-people-clash dept.
The Slashdolt writes "After a stern criticism from Linus, the long-time kernel hacker Alan Cox has decided to walk away as the maintainer of the TTY subsystem of the Linux Kernel, stating '...I've had enough. If you think that problem is easy to fix you fix it. Have fun. I've zapped the tty merge queue so anyone with patches for the tty layer can send them to the new maintainer.'" A response to a subsequent post on the list makes it quite clear that he is serious.

DHS Pathogen Lab To Be Built In "Tornado Alley" 275

Posted by kdawson from the don't-think-we're-in-kansas-anymore dept.
Hugh Pickens writes "The Washington Post reports that Department of Homeland Security is relying on a rushed, flawed study to justify its decision to locate the $700 million National Bio and Agro-Defense Facility for highly infectious pathogens in a tornado-prone section of Kansas. A GAO report says that it is not 'scientifically defensible' to conclude that lab can safely handle dangerous animal diseases in Kansas. Such research has been conducted up to now on a remote island on the northern tip of Long Island, NY. 'Drawing conclusions about relocating research with highly infectious exotic animal pathogens from questionable methodology could result in regrettable consequences,' the GAO warned in its draft report. Critics of moving the operation to the mainland argue that a release could lead to widespread contamination that could kill livestock, devastate a farm economy, and endanger humans. Along with the highly contagious foot-and-mouth disease, NBAF researchers plan to study African swine fever, Japanese encephalitis, Rift Valley fever, and other viruses in the Biosafety Level (BSL) 3 and BSL-4 livestock laboratory capable of developing countermeasures for foreign animal diseases. According to the article, DHS lobbied a Congressional committee to try and convince them that the GAO report was flawed, and to head off any hearings on the controversy. Despite this, the House Energy and Commerce Committee's oversight and investigations subcommittee plans to hold a hearing Thursday on the risk analysis."

You, Too, Can Learn Echolocation 133

Posted by timothy from the and-you-swear-this-isn't-a-joke dept.
The Narrative Fallacy writes "Wired reports that with just a few weeks of training, you can learn to 'see' objects in the dark using echolocation the same way dolphins and bats do. Acoustic expert Juan Antonio Martinez at the University of Alcalá de Henares in Spain has developed a system to teach people how to use echolocation, a skill that could be particularly useful for the blind and for people who work under dark or smoky conditions, like firefighters — or cat burglars. 'Two hours per day for a couple of weeks are enough to distinguish whether you have an object in front of you,' says Martinez. 'Within another couple weeks you can tell the difference between trees and pavement.' To master the art of echolocation, you can begin by making the typical 'sh' sound used to make someone be quiet. Moving a pen in front of the mouth can be noticed right away similar to the phenomenon when traveling in a car with the windows down, which makes it possible to 'hear' gaps in the verge of the road. The next level is to learn how to master 'palate clicks,' special clicks with your tongue and palate that are better than other sounds because they can be made in a uniform way, work at a lower intensity, and don't get drowned out by ambient noise. With the palate click you can learn to recognize slight changes in the way the clicks sound depending on what objects are nearby. 'For all of us in general, this would be a new way of perceiving the world,' says Martinez."

With twenty machines, I'm going to go out on a limb and say don't! You have a large enough user base that you should use a hard disk image backup system, yet a small enough base that the infections would be manageable. Since your primary server isn't windows you may want to set up your network so each user workstation cannot connect to the others, then let them be on their way. The CPU usage of constant disk scanning is a drag on the user's machine. Weighed 20 of them versus the time for you to recreate an image of a particular users disk then swap them out. Besides, if one particular user is a problem it will play out as negative reinforcement for whatever they are doing to get infected.
My reasoning is that users often disable the scan anyway, so you would be trying to combat that behavior by tweaking the application/system security policies. Don't waste your time, if they get infected waste theirs. They won't do it again....
