Damn Vulnerable Linux — Most Vulnerable Linux Ever 227

Posted by timothy from the in-context-it's-barely-vulgar dept.
An anonymous reader writes "Usually, when installing a new operating system, the hope is that it's as up-to-date as possible. After installation there's bound to be a few updates required, but no more than a few megabytes. Damn Vulnerable Linux is different; it's shipped in as vulnerable a state as possible. As the DVL website explains: 'Damn Vulnerable Linux (DVL) is everything a good Linux distribution isn't. Its developers have spent hours stuffing it with broken, ill-configured, outdated, and exploitable software that makes it vulnerable to attacks. DVL isn't built to run on your desktop – it's a learning tool for security students.'"

Ubuntu's "Lucid Lynx" Enters Beta 366

Posted by timothy from the but-that-danged-button-arrangement-sucks dept.
ActionDesignStudios writes "The upcoming release of Ubuntu, titled 'Lucid Lynx,' has just entered the beta cycle. Alongside the usual desktop and server versions, a special version has been released that is designed to run on Amazon's EC2 cloud service. This release of Ubuntu does away with the brown 'Human' Gnome theme we've all become accustomed to, replaced by a new version Canonical says is inspired by light. The new release also includes much better integration with social networking services such as Twitter, identi.ca and Facebook, among others."

Scientists Use Sex-Crazed Bugs As Pesticide 107

Posted by samzenpus from the doin'-it-hopper-style dept.
ByronScott writes "In today's 'gross news' category, some female insects just might be getting lucky. As an alternative to toxic pesticides, scientists at the Hebrew University of Jerusalem have created 'super-sexed' sterilized male leafhoppers to knock bug boots with females in the wild, resulting in decreased populations. Yes, that means that the female bugs will miss out on the joys of motherhood, but the idea that the insects will be having some fun instead of being gassed to death by poisons is pretty cool."

Half-Male, Half-Female Fowl Explain Birds' Sex Determination 117

Posted by timothy from the fish-nor-fowl-except-fowl dept.
Kanan excerpts from a BBC report out of Scotland: "A study of sexually scrambled chickens suggests that sex in birds is determined in a radically different way from that in mammals. Researchers studied three chickens that appeared to be literally half-male and half-female, and found that nearly every cell in their bodies — from wattle to toe — has an inherent sex identity. This cell-by-cell sex orientation contrasts sharply with the situation in mammals, in which organism-wide sex identity is established through hormones." Kanan also supplies this link to some pictures of the mixed-cell birds.

Throttle Shared Users With OS X — Is It Possible? 403

Posted by timothy from the throttle-the-snot-instead dept.
whisper_jeff writes "I work in a design studio where the production director is also the owner's son (translation = he can do no wrong). He is fond of accessing a designer's computer via filesharing and working directly on files off of the designer's computers rather than transferring the files to his computer to work on them there. In so doing, he causes the designer's computer to grind to a near-halt as the harddrive is now tasked with his open/save requests along with whatever the designer is doing. Given that there is no way he's going to change his ways (since he doesn't see anything wrong with it...), I was wondering if there was a way to throttle a user's shared access to a computer (Mac OSX 10.5.8) so that his remote working would have minimal impact on our work. Google searches have revealed nothing helpful (maybe I should Bing it... :) so I was hoping someone with more technical expertise on Slashdot could offer a suggestion."

Funeral Being Held Today For IE6 194

Posted by samzenpus from the good-riddance dept.
An anonymous reader writes "More than 100 people, many of them dressed in black, are expected to gather around a coffin Thursday to say goodbye to an old friend. The deceased? Internet Explorer 6. The aging Web browser, survived by its descendants Internet Explorer 7 and Internet Explorer 8, is being eulogized at a tongue-in-cheek 'funeral' hosted by Aten Design Group, a design firm in Denver, Colorado."

Printing Replacement Body Parts 101

Posted by kdawson from the portrait-mode dept.
Deep Penguin sends in a piece that appeared in The Economist a couple of weeks back about a developing technology to "print" body parts for transplant. "A US and an Australian company have developed the $200,000 machine, which works by depositing stem cells and a 'sugar-based hydrogel' scaffolding material. (The stem cells are harvested from a transplant patient's own fat and bone marrow, to avoid rejection down the line.) The companies are Organovo, from San Diego, specializing in regenerative medicine, and Invetech, an engineering and automation firm in Melbourne, Australia. The initial targets are skin, muscle, and 'short stretches of blood vessels,' which they hope to have available for human implantation within five years. Down the line, they expect the technology could even print directly into the body, bypassing the in-vitro portion of the current process."

Officials Sue Couple Who Removed Their Lawn 819

Posted by kdawson from the revenge-of-the-lawn dept.
Hugh Pickens writes "The LA Times reports that Orange County officials are locked in a legal battle with a couple accused of violating city ordinances for replacing the grass on their lawn with wood chips and drought-tolerant plants, reducing their water usage from 299,221 gallons in 2007 to 58,348 gallons in 2009. The dispute began two years ago, when Quan and Angelina Ha tore out the grass in their front yard. In drought-plagued Southern California, the couple said, the lush grass had been soaking up tens of thousands of gallons of water — and hundreds of dollars — each year. 'We've got a newborn, so we want to start worrying about her future,' said Quan Ha, an information technology manager for Kelley Blue Book. But city officials told the Has they were violating several city laws that require that 40% of residential yards to be landscaped predominantly with live plants. Last summer, the couple tried to appease the city by building a fence around the yard and planting drought-tolerant greenery — lavender, rosemary, horsetail, and pittosporum, among others. But according to the city, their landscaping still did not comply with city standards. At the end of January, the Has received a letter saying they had been charged with a misdemeanor violation and must appear in court. The couple could face a maximum penalty of six months in jail and a $1,000 fine for their grass-free, eco-friendly landscaping scheme. 'It's just funny that we pay our taxes to the city and the city is now prosecuting us with our own money,' says Quan Ha."

PC-BSD 8.0 Release Focuses On Desktop Use 154

Posted by kdawson from the fresh-bits dept.
donadony writes "Last Monday PC-BSD 8.0 was released. PC-BSD is based on FreeBSD and uses KDE as its default desktop environment. PC-BSD is designed to make BSD much easier for desktop use. The 8.0 release includes support for 3D acceleration with NVIDIA drivers on amd64 and improvements in the USB subsystem. The PC-BSD team has also developed a friendly package manager system with a simple-to-use GUI tool (see the screenshots tour). For a full list of changes, refer to the changelog."

Creating Electric Power From Light Using Gold Nanoparticles 77

Posted by Soulskill from the nanite-power-supply dept.
cyberfringe writes "Professor of Materials Science Dawn Bonnell and colleagues at the University of Pennsylvania have discovered a way to turn optical radiation into electrical current that could lead to self-powering molecular circuits and efficient data storage. They create surface plasmons that ride the surface of gold nanoparticles on a glass substrate. Surface plasmons were found to increase the efficiency of current production by a factor of four to 20, and with many independent parameters to optimize, enhancement factors could reach into the thousands. 'If the efficiency of the system could be scaled up without any additional, unforeseen limitations, we could conceivably manufacture a 1A, 1V sample the diameter of a human hair and an inch long,' Prof. Bonnell explained. The academic paper was published in the current issue of ACS Nano. (Abstract available for free.) The significance? This may allow the creation of nano-sized circuits that can power themselves through sunlight (or another directed light source). Delivery of power to nanodevices is one of the big challenges in the field."
