+ - The Science of the Perfect Kiss

Submitted by Hugh Pickens writes
Hugh Pickens writes (1984118) writes "Just in time for Valentine's day, the Pittsburg Post-Gazette reports kissing has an important biological function because the chemical information exchanged during a kiss — the unleashing of a "chemical choir" of assorted hormones in the brain — is sufficient to assess and rule out long-term mating potential as the body experiences a rise in chemicals including oxytocin, dopamine, serotonin and adrenaline — the stuff that creates a feeling of euphoria, attachment and excitement. "Behind a kiss is a very rich and complicated exchange of tactile cues, odors and other sensations that we seem to be hard-wired to process," says Dr. Gordon Gallup, one of the foremost researchers into romantic attraction, which, he admits is "not a very big field." But a kiss is not just about exchanging hormones, says Helen Fisher, a noted Rutgers University anthropologist and author of books on the science of romantic attraction. "It's really exchanging a huge amount of social information, too, about daily habits and intentions," she said. "You can see, smell, taste, hear and feel the other person, and you may be thinking, 'oh, he smells good, he must be very clean.' Then again, he may smell of cigarettes, and you think, 'oh, no, that's not good.' Or he may be coming on too strong, and you tell him to take it easy, and he does, and you think, 'Oh, he's a good listener.' " Women, it seems, gather more information from kissing than men do and are more likely to consider a good kiss critical to determining the future of the relationship. Men, not so much. "I would say on Valentine's Day, and every day, it is important," says says Sheril Kirshenbaum, a research scientist at the University of Texas in Austin. "It is the ultimate way to express yourself beyond what words can do.""

24 Hour Laptops From HP? 205

daveyboy79 writes "This article from the BBC shows HP's new laptop, the HP EliteBook 6930p. Configured with several options, such as the 80Gb SSD and the mercury-free LED displays, it allows users to get 24 hours of non-stop computing." The real question is, are we talking 24 hours of word processing? Or 24 hours of actually using your computer?

+ - Finding an IT job without formal education 2

Submitted by Pensive Idiot
Pensive Idiot (941485) writes "I entered into college with high aspirations of getting an economics degree in 3-3.5 years, but the more I try to get my degree the more I begin to believe that knowledge is a commodity reserved for the rich. I just started my second year in school and I am beginning to think/worry that this will be the last year I can afford. I have been working with computers since I was in high school and in an IT position (part time) with a small office on campus for the last year, but I am not formally trained in any way. I notice that many individuals in IT are self taught, but they have all been in the industry for at least 10 years. I am very knowledgeable with Linux, Windows, Servers, Desktops, Networking and a list of programming languages, but it seems that everyone wants a CS/MIS/IT degree, or a list of certifications, neither of which I can afford.
My question is simply, does the self-taught individual still have a chance in today's IT job market, and if so, what skills do I need to be competitive and how can I prove to a potential employer that I have them?"

Submitted by Anonymous Coward
An anonymous reader writes "Want to run software off of your thumb-drive without using Sandisk's proprietary U3 platform? Then see Put Your USB Drive To Work: 5 Strategies For Going Mobile. The tips, of middling but useful technical intensity, include where to get robust encryption for your thumb drive for free (hint: Try TrueCrypt); where to find free application suites and individual apps (try the OperaUSB browser); and how to run a standalone operating system off your USB drive. For the latter, the article shows how to use BartPE, a utility that builds a copy of Windows's Preinstallation Environment from an existing Windows install. With tools like this, do you think USB drives are about to finally fulfill their promise as mobile repositories which make the concept of maintaining separate PCs at different locations obsolete?"

+ - OS X unable to write to large volumes using Samba?

Submitted by
groovemaneuver
groovemaneuver writes "I'm the IT Manager of a small/mid-sized college network that consists mostly of GNU/Linux servers with a near 50/50 split of Apple OS X and MS Windows XP workstations. We have a Samba-based file server with a 4 TB RAID, and the WinXP boxes connect, read, and write normally. However, the Mac boxes can connect and read, but they see every share that is hosted on the RAID as having 0KB available, and refuse to write. As a test, we created an identically-configured share hosted on the server's OS drive (about 80 GB), and the Macs connected just fine. We also have a few GNU/Linux workstations, and they can all connect to the shares without issues. Is there a limit to how large a Samba share can be before Mac clients crap out? Are we the only ones dealing with this? Is there a known solution? (my Google skills are usually pretty good, but I couldn't find anything)"

An anonymous reader writes "Hey, I am a developer and am about to move to a Linux (Ubuntu for now) Machine, even though I develop in Windows XP. So I would like to get everyone's opinion or thoughts on which is better and why out of Parallels for Linux and VMWare and KVM. My main concerns are speed and data integrity... I would like to have share virtual hard drives so multiple machines can use the same data. I would like Speed as I will be developing inside of these virutal machines... Any help would be appreciated. Regards C"
