Submission + - Lua Scripting Language Support Coming To NetBSD Kernel (

An anonymous reader writes: With the release of NetBSD 7, it will be possible to extend kernel sub-systems and write device drivers in the Lua scripting language. A Lua interpreter is being added to the NetBSD kernel, a proper programming kernel interface, and a user-space interface for loading Lua scripts into the NetBSD kernel in real-time. Reasons expressed for adding Lua support to the NetBSD kernel is "modifying software written in C is hard for users", providing a rapid application development approach to drivers and the kernel, and better configuring of kernel sub-systems. Python and Java script support was looked at too, but they ended up settling for Lua. Lua scripting support for the kernel has been worked on since 2010.

Submission + - Can You Potty Train a Cow? (

sciencehabit writes: Think potty training a child is hard? Try teaching a cow when and where to do its business. The bovines can defecate nine to 16 times daily, and pee seven to nine times, creating big hygiene problems on dairy and beef farms. So cueing the animals to go in the right place would be a big help for managing manure. But past techniques—including training cows to respond to mild electric shocks—have proven ineffective or impractical for wide use. To see if they could come up with a better potty prompt, the scientists tested a series of stimuli on a dozen Holstein cows. The milkers stood in or walked through a footbath filled with water, for example, or had air or water sprayed on their feet. Alas, "[n]one of our tests reliably stimulated defecation," the team reports. Maybe bovine diapers instead?

Submission + - When Google got flu wrong (

ananyo writes: "When influenza hit early and hard in the United States this year, it quietly claimed an unacknowledged victim: one of the cutting-edge techniques being used to monitor the outbreak. A comparison with traditional surveillance data showed that Google Flu Trends, which estimates prevalence from flu-related Internet searches, had drastically overestimated peak flu levels. The glitch is no more than a temporary setback for a promising strategy, experts say, and Google is sure to refine its algorithms. But with flu-tracking techniques based on mining of web data and on social media taking off, Nature looks at how these potentially cheaper, faster methods measure up against traditional epidemiological surveillance networks."

Submission + - Killing Your Sexual Desires for Academic and Intellectual Pursuits? 6

An anonymous reader writes: In the past few months, I have been applying to a multitude of graduate schools. Recently, I was accepted into a Ph.D. in computer science program at a fairly prestigious and demanding institution. Like most Slashdot readers, I have always been an exceptional student throughout high school and my undergraduate studies. However, as a heterosexual male individual, there has always been a persistent desire to associate myself with females in an effort to find love, have sex, and to be in a relationship. I have learned the hard way that this is often a colossal distraction from one's schooling and I would like to train myself to become more apathetic to such desires in preparation for the difficult but intellectually awarding years of graduate school that lay ahead. So, fellow Slashdot users, I ask you a rather odd but serious question on none other than Valentine's Day: How do you kill your sexual desires to enable you to focus more on academic and intellectual goals?

Submission + - Collaborative LaTeX editor with Preview in your web browser ( 1

Celarent Darii writes: Slashdot readers have undoubtably heard of Google Docs and the many other online word processing solutions that run in the browser. However, as a long-time user of TeX and LaTeX, these solutions are not my favorite way of doing things. Wouldn't it be nice to TeX something in your browser? Well, look no further, there is now a Online collaborative LaTeX editor with integrated rapid preview. Some fantastic features: quasi-instant preview, automatic versioning of source, easy collaboration and you can even upload files and pictures. Download your project later when you get home. Are you a TeX guru with some masterpieces? Might I suggest uploading them? For the beginner: you can start here.

Full disclosure: I am not affiliated with the site in anyway, just a fan. Hope exposure on Slashdot gets the word out on this great resource, which is very useful while travelling!


Submission + - Inventing the Chromebook - First Version was Based on Firefox (

Andy Prough writes: Former Google engineer Jeff Nelson has written a fascinating blog post about how he created "Google OS", the forerunner to Chrome OS. Last August, he finally received a patent for it, but his work began in 2006, and the first versions of the OS were built on Firefox and a "bare-bones Linux distribution" that could execute any Linux program. In fact, when he first started writing the OS, Chrome itself did not exist, and the whole purpose for his work was to create a system that loaded fully — and only — into system RAM. This purpose grew out of his frustration with wait times as he wrote webapps for Google, and found himself waiting 30-45 seconds just to restart a web browser. By moving the entire OS to RAM, he was able to cut the Firefox restart time from 45 seconds to 1 second, and found similar speed increases for other mundane tasks. He built himself a "Chromebook" and used it as his primary development box for over a year. The fact that his boss and Google management originally had no interest in his project makes this story all the better. This blog post is a very interesting read, as it discusses the beginnings of the range of Google webapps that were ultimately created to "replace any and all functionality normally found on a desktop".

Submission + - What is the best programming language for a 12-year-old to learn? 3

wintersynth writes: My friend is sending his 12-year-old to a tech summer camp and wants to know the best language for him to learn. It looks like Java and Python are the main options, both applied to game programming. There are also classes using the Lego Mindstorm scripting language, and Scratch. Slashdotters, I assume you've run into this question before, and I could use the help. Programming tools have changed a lot since I was learning SmartBASIC on a Coleco Adam as a kid. I want to recommend something that will be powerful enough to show him the unlimited possibilities in programming, but easy enough to maintain his interest and not discourage him. What do you teach your kids? What has been effective?

Submission + - Do Not Track ineffective and dangerous, says researcher (

Seeteufel writes: Nadim Kobeissi, security researcher, describes the Do Not Track standard of the W3C as dangerous.

In fact, Google’s search engine, as well as Microsoft’s (Bing), both ignore the Do Not Track header even though both companies helped implement this feature into their web browsers. Yahoo Search also ignored Do Not Track requests. Some websites will politely inform you, however, of the fact that your Do Not Track request has been ignored, and explain that this has been done in order to preserve their advertising revenue. But not all websites, by a long shot, do this.

The revalations come as Congress and European legislators consider to tighten privacy standards amidth massive advertiser lobbying. "Do not track" received strong support from the European Commission.


Submission + - Gut Bacteria Conspired in Melamine Poisonings (

sciencehabit writes: In 2008, nearly 300,000 infants in China got sick from milk formula tainted with melamine, a plastics additive that was used illegally to bulk up the formula's apparent protein content. Now, a study in rats implicates bacteria living in the gut as unwitting accomplices in this mass poisoning. The bacteria convert some melamine to cyanuric acid, whichwas present in high concentrations in fatal kidney stones. The work helps clarify how melamine toxicity arises and also drives home the key role that gut bacteria play in human health.

Submission + - Punkbuster Service Goes Down, Hundreds of Online Game Servers Affected (

MojoKid writes: "PunkBuster, the anti-cheating service implemented in hundreds of online games, is down. As of the time of writing, the official PunkBuster website is up and down, after having been completely down for the past couple of hours. On Twitter, there are numerous reports of gamers who've been unable to play online in the most popular PunkBuster-backed title of the moment, Battlefield 3. EA has gone as far as to post an interim fix. Applying the fix is a simple matter of extracting an archive and then overwriting a couple of files inside of your Battlefield 3 install folder. While EA has little power over PunkBuster's ability to get things 100% functional again, this issue does highlight the fact that third-party solutions are not always the way to go."
