Got that hacking jones, but can’t find anyone to hack with? Head on over to JustHackIt, a site aimed at developers that launched last night. It is a place for developers to find each other, work on projects, and maybe even start a company. Developers can post projects they want to do and search through postings from other hackers. The site describes itself this way:

In the current economic climate, businesses of every size are looking to reduce their spending wherever possible. Open source software, which has no upfront licensing fees, is one way of achieving significant savings.

However, in order to protect their enormous revenue streams, large software corporations have invested millions in spreading fear, uncertainty, and doubt (FUD) about the security of open source software. In this post, I will examine and debunk five commonly held myths about open source security and why large corporations are promoting a “fear factor” mentality around open source software.

According to new research from the Monell Center, odors from skin can be used to identify basal cell carcinoma, the most common form of skin cancer. The findings, presented at the 236th meeting of the American Chemical Society, may open doors to development of new methods to detect basal cell carcinoma and other forms of skin cancer.

The researchers sampled air above basal cell tumors and found a different profile of chemical compounds compared to skin located at the same sites in healthy control subjects. “Our findings may someday allow doctors to screen for and diagnose skin cancers at very early stages,” said Michelle Gallagher, PhD.

Activision’s Guitar Hero III: Legends of Rock may have drawn a less-favorable reception from critics due to its comparatively limited instrument set, but it went on to dramatically outsell its most direct competitor, MTV Games’ Rock Band. With Guitar Hero World Tour, the publisher has addressed that feature deficiency in a major way by introducing a five-pad drum set, karaoke tracks, and a robust song creator, among other additions.

With those features slated to arrive for all editions of the game, developer Vicarious Visions has a few Wii-specific tweaks up its sleeve. RedOctane representatives confirmed for GameSpot today that Guitar Hero World Tour on the Wii will include Mii integration in the new Mii Freestyle mode.

Just one night without sleep can increase the amount of the chemical dopamine in the human brain, according to new imaging research in the August 20 issue of The Journal of Neuroscience. Because drugs that increase dopamine, like amphetamines, promote wakefulness, the findings offer a potential mechanism explaining how the brain helps people stay awake despite the urge to sleep.

However, the study also shows that the increase in dopamine cannot compensate for the cognitive deficits caused by sleep deprivation.

One of the few remaining Internet-free havens vanished Wednesday as American Airlines launched airborne e-mail, Web and other online services on some of its longer nonstop flights.

The move could create a new stream of revenue for an aviation industry facing high fuel prices and other challenges. But it also could create new headaches as passengers retrieve sensitive e-mails and websites in confined quarters.

This morning at the Leipzig Games Convention, Sony Computer Entertainment Europe officially revealed the PSP-3000. Shortly thereafter, Sony Computer Entertainment America formally announced that the latest hardware revision of the PlayStation Portable would ship worldwide in October, or in roughly two months’ time.

SCEA’s announcement gave more concrete details about the PSP-3000 and Sony’s plans for it outside Europe. The handheld is the same width as the PSP-2000, the slimmer model Sony unveiled at E3 2007, and will sport the same video output functionality. However, the new model will now output gameplay in interlaced video format compatible with non-progressive video displays.

Although Windows XP was Microsoft’s preferred desktop operating system for an unprecedented length of time, it became something of a PR nightmare for the software giant. Windows XP is full of security holes and is very easy to compromise. When Microsoft created Windows Vista, its primary goal was to address all of the security problems that have been plaguing Windows XP for so many years.

Although Windows Vista security is far stronger than that of Windows XP, even running an out-of-the-box configuration, you need to know how to use some of the new security features in order to get the most out of the OS. This list of the top Vista security tips can help you run a truly secure Vista installation.

India figures among the top 10 spam sending countries, accounting for nearly 3% of spam sent globally in the second quarter of 2008, according to enterprise security firm Secure Computing’s Internet Threats report. Spam or unsolicited e-mails sent from emerging markets is expected to grow as internet infrastructure improves.

The top 10 countries account for 55% of the world’s spam volume. Top-ranked US, with a 16.56% contribution, sends more than twice as much spam as the next largest contributor, Russia. Turkey, Brazil, Italy and China follow the top two countries. India is ranked ninth in the list.

Linux project lead Linus Torvalds has said it is not easy to become a major contributor to the Linux kernel.

In an email interview with ZDNet.com.au sister site ZDNet.co.uk last week, Torvalds said that, while it was relatively easy for coders and organisations to contribute small patches, the contribution of large patches, developed in isolation, could lead to both new and established contributors becoming frustrated.
