An anonymous reader writes “Zen and the Art of Programming published an article about MacRuby’s new experimental 0.5 branch (project blog entry here). According to the included benchmarks, Apple’s version of Ruby could already, at this early stage of its development, be about three times as fast as the fastest Ruby implementation available elsewhere.”

RobGoldsmith writes in with news of the further adventures of Charles Simonyi, whose first trip to the ISS we discussed a couple of years ago. The Russian Soyuz vehicle carrying Simonyi and two others docked a day after the US space shuttle Discovery landed in Florida. “Space Adventures, Ltd. … announced today that its orbital client Charles Simonyi and his crew successfully arrived at the International Space Station after launching on-board the Soyuz TMA-14 spacecraft from the Baikonur Cosmodrome in Kazakhstan on March 26. The spacecraft docked to the ISS at 9:05 am (EDT) with Dr. Simonyi and Expedition 19 crew members Russian cosmonaut Gennady Padalka and NASA astronaut Michael Barratt. They were greeted at approximately 12:30 p.m. (EDT) by the Expedition 18 crew…”

mmmscience writes “Researchers in Switzerland think they had identified the regions of the brain responsible for creating phantom limbs and the senses that go along with them. Scientists studied a stroke victim who claimed that the phantom limb of her now-paralyzed left arm could do a number of things a normal limb could do, including ‘scratch an itch on her head, with an actual sense of relief.'”

TechCrunch is running a story about three possible security issues with Google Docs recently uncovered by researcher Ade Barkah. It turns out that an image embedded into a protected document is given a URL which is not protected, allowing anyone who knows or guesses it to see the image regardless of permissions or even the existence of the document. Barkah also pointed out that once you’ve shared a document with another person, that person can see diagram revisions from any point before they gained access, forcing you to create a new document if you need to redact something. The last issue, the mechanics of which he disclosed only to Google, affects the document-sharing invitation forwarding system, which can allow somebody access to your documents after you’ve removed their permissions. Google made a blog post to respond to these concerns, saying that they “do not pose a significant security risk,” but are being investigated. We previously discussed a sharing bug in Google Docs that was fixed earlier this month.

ryanleary writes “I am currently a junior computer science major at a relatively competitive university. I intend to remain here for some graduate work, and I would like to get a master’s degree. What would be a good field to study? An MS in computer science appears to be highly theoretical, while an MS in IT seems more practical due to its breadth (covering some management, HCI, and design). What looks best on a resume, and where might I expect to make more money in the not-too-distant future? Computer Science, Information Technology, or something different altogether — perhaps an MBA?”

uctpjac writes “London media lawyer Emily MacManus argues that UK libel law has three features which make it the ‘defamation tourism’ capital of the world and a serious threat to web free speech. First, there is no free speech presumption in the UK as there is, for example, in the US. Second, every access of a web page is considered to be a separate act of publication in the UK (unlike the US, where ‘original publication’ holds). Third, ‘no-win-no-fee’ libel litigation is now allowed in the UK. If any blog, anywhere, publishes something you’d like taken down, threaten libel action in the UK: no one except the super-rich can afford to even take these cases to court, so media lawyers advise publishers to ‘take it down, take it down quickly, take it down again.’ There’s not much chance that the judges will move the law any time soon because they just aren’t seeing the cases that could cause them to set new precedent.”

On Wednesday, we discussed news that AT&T had begun sending takedown notices to users whom the RIAA has accused of illegally downloading copyrighted works. Cox and Comcast are both cooperating with the RIAA in that regard as well. However, while Cox seems willing to shut off service in the case of repeat offenders, Comcast denied that it was considering a similar penalty, and AT&T said they’ll flat out refuse to terminate service on the RIAA’s word alone; it will take a court order. They seem satisfied with the effect letters have had on inhibiting such downloads: “‘It’s a standard part of everybody’s terms of service,’ [AT&T senior executive vice president Jim Cicconi] said. ‘If somebody is engaging in illegal activity, it basically gives us the right to do it…We’re not a finder of fact and under no circumstances would we ever suspend or terminate service based on an allegation from a third party. We’re just simply reminding people that they can’t engage in illegal activity.’ Cicconi said the company began testing this kind of ‘forward noticing’ late last year and even experimented with sending certified letters. Cicconi said the notices worked. The company saw very few repeat offenders.”

Deepa Sivarajan sends word that the journal Transformative Works and Culture has published an issue that focuses on games, containing a variety of articles which examine how games interact with modern culture. One essay takes a look at how developers gain an understanding of the systems and structures that drive gameplay, and another discusses motivation and “participatory culture” in games that have a substantial degree of user design involvement, such as mods and addons. There’s also an evaluation of how the enthusiast press affects the perceived value of games. The issue includes game-related book reviews and interviews, which can be found at the bottom of the full list of articles.

Technology Review has promising news on the AIDS front: researchers have captured HIV T cell transmission on video. The upshot could be new avenues of treatment. “The resulting images and videos show that, once an infected cell adheres to a healthy cell, the HIV proteins… migrate within minutes to the contact site. At that point, large packets of virus are simultaneously released by the infected cell and internalized by the recipient cell. This efficient mode of transfer is a distinct pathway from the cell-free infection that has been the focus of most prior HIV studies, and reveals another mechanism by which the virus evades immune responses that can neutralize free virus particles within the body.”

Hugh Pickens writes “New cognitive research shows that 3-year-olds neither plan for the future nor live completely in the present, but instead call up the past as they need it. ‘There is a lot of work in the field of cognitive development that focuses on how kids are basically little versions of adults trying to do the same things adults do, but they’re just not as good at it yet. What we show here is they are doing something completely different,’ says professor Yuko Munakata at the University of Colorado at Boulder. Munakata’s team used a computer game and a setup that measures the diameter of the pupil of the eye to determine mental effort to study the cognitive abilities of 3-and-a-half-year-olds and 8-year-olds. The research concluded that while everything you tell toddlers seems to go in one ear and out the other, the study found that toddlers listen, but then store the information for later use. ‘For example, let’s say it’s cold outside and you tell your 3-year-old to go get his jacket out of his bedroom and get ready to go outside,’ says doctoral student Christopher Chatham. ‘You might expect the child to plan for the future, think “OK it’s cold outside so the jacket will keep me warm.” But what we suggest is that this isn’t what goes on in a 3-year-old’s brain. Rather, they run outside, discover that it is cold, and then retrieve the memory of where their jacket is, and then they go get it.'”
