Could the Tumbleweed Rover Dominate Mars?
astroengine writes "Mars has been visited by orbiters, landers and rovers, but could the future of Martian exploration be inspired by a wind-blown sphere? NASA and other research institutions have been developing the Mars Tumbleweed rover for the last decade, but with the help of the Planetary Science Institute, the Tumbleweed is now vying for some serious funding to further develop the technologies required. Although the Tumbleweed would be wholly dependent on the prevailing winds on the Martian surface, the lightweight and relatively cheap design could lead the way for a 'swarm' of independent Tumbleweeds to explore vast regions of the planet (video link). In 2003 and 2004, NASA even tested an inflatable Tumbleweed prototype on Greenland and Antarctica — it traversed hundreds of miles with ease, continually relaying location and environmental data."

YouTube Makes Captioning Available To All
adeelarshad82 writes "Google's YouTube announced that it has moved its automatic speech-recognition and closed-captioning technology out of beta and has now made it available to the YouTube community at large. Most, if not all, YouTube videos now include a 'CC' button that, if pressed, will automatically generate the closed-captioning technology. The technology processes the audio feed using the speech-recognition technology used in the core voice search feature that has also been built into the Android voice search feature, the GOOG-411 phone search, and other products."

California Lake's Arsenic Hints At a Shadow Biosphere
MichaelSmith writes "Scientists think that there might be arsenic-based life in Mono Lake, California. If it's shown to exist, such life could have evolved independently from our own, or it could have forked from ours at a very early stage."

Best WAP For Dense Crowds?
An anonymous reader writes "A local community organization has asked me to help them set up WiFi access for an upcoming event, with some unusual (to me) requirements. All users (up to 500 people) will occupy a relatively small area and more-or-less have line-of-sight to the WAP, so issues like signal strength and wall penetration don't matter. Security also does not matter, as we plan to open this to anyone wanting to connect. Cost always matters, but we realize a $50 Linksys or three won't cut it here.
In the past, I have used Cisco AP1200s for a few dozen users to great satisfaction, but they only handle 50 connections at a time, and practically count as antiques at this point anyway. My research on the matter tells me that 802.11n performs far better in this regard, but I want to support 802.11g as well. I have no objection to using two APs to split those apart (with n limited to 5.8GHz, as per the suggestion of several comments in a recent Ask Slashdot), but physical constraints make it preferable to minimize the total number of APs needed — Ten WRT54s might cost about the same as one Aironet, but I only have three good places to mount these.
I welcome any suggestions and real-world experiences with similar situations, including the ever-popular Ask Slashdot refrain of 'What kind of idiot would do it like that, when you can just do this?' Ideally, I would like to know model numbers and how well they held up under real-world loads comparable to my situation."

California To Create Public Animal Abuser Registry
An anonymous reader writes "California legislators are moving forward with plans to create a public, online, animal abuser registry identical in function to the public sex offender registry. Is this the slippery slope to further government mandated lists and registries?"

Law Prevents British Websites From Being Archived
Lanxon writes "The law that allows the US Internet Archive to collect and preserve websites does not apply to British archivists. In fact, experts from the Archive and many other archivist institutions argue that the only way the millions of Britain's websites could be legally archived is if British law itself was amended, reports Wired in an investigation published today. Currently, archivists have to seek permission from webmasters of every single site before they are able to take snapshots and retain data."

Bluetooth 4.0 Devices To Make the Scene Later This Year
Engadget is reporting that new Bluetooth 4.0 devices could be hitting the scene later this year, and it looks like Bluetooth low energy has been added to the spec. "But don't expect any dramatic changes in battery life for most of your gadgets: while the low energy spec introduces connectivity to a host of lower-power devices that have in the past relied on proprietary technology (such as watches, pedometers, and cats), your traditional Bluetooth devices, such as phones and laptops, will consume roughly the same amount of power. Indeed, the low energy spec is merely throwing smaller devices (with smaller amounts of data to transfer) in to the mix: if you want Trans-Siberian Orchestra to sound as glorious as ever on your wireless headphones, you'll need to push as much data (and hence draw as much power) with version 4 as you would with version 3."

Microsoft "Courier" Pictures
tekgoblin writes to let us know that Gizmodo has some early shots of the new prototype "Courier" booklet (foldable tablet) on the way from Microsoft. "Courier is a real device, and we've heard that it's in the 'late prototype' stage of development. It's not a tablet, it's a booklet. The dual 7-inch (or so) screens are multitouch, and designed for writing, flicking and drawing with a stylus, in addition to fingers. They're connected by a hinge that holds a single iPhone-esque home button. Statuses, like wireless signal and battery life, are displayed along the rim of one of the screens. On the back cover is a camera, and it might charge through an inductive pad, like the Palm Touchstone charging dock for Pre."

Valve Announces <em>Portal 2</em>
eldavojohn writes "Enough rumors, Portal 2 is due out for 2010. Valve also let users know through an announcement on Steam. Game Informer seems to be the de facto provider of Portal 2 information so far. Prepare yourselves for more aperture science! Notice anything funny about the underlined letters in Steam's announcement?"

Dr. NakaMats Is the World's Most Prolific Inventor
MMBK writes to share an interesting look at Dr. "NakaMats" Nakamatsu, mastermind behind a world-record 3,000 patents. The 81-year-old scientist has inventions like the "PyonPyon" spring shoes, the karaoke machine, and others. He's also at least partly to blame for things like the digital watch, the floppy disk, and CDs. "Dr. Nakamatsu harbors other ambitions too: in 2007, he took his penchant for political campaigning to a new level, becoming a candidate in the gubernatorial election in Tokyo, and the election for the Upper House. Although he failed to get a seat, Dr. NakaMats has other tricks up his sleeve. In 2005 he was awarded the Ig Nobel prize for Nutrition, for photographing and retrospectively analyzing every meal he has consumed during a period of 34 years (and counting). By the time he dies at the age of 144 (a goal he maintains with an elaborate daily ritual that rejuvenates his body and triggers his creative process), he intends to patent 6,000 inventions."

New Heat-Reduced Magnetic Solder Could Revolutionize Chip Design
A new heat-reduced soldering technique using magnets may lead to some revolutionary changes in the way chips are manufactured. Details are scant since the inventor seems to be playing it close to the vest for now in hopes of attracting chipmaker interest. "The result is a tin-silver alloy that contains a dispersion of iron particles tens of micrometers in diameter. When a magnetic field is applied to the solders, two things happen. First, the iron particles heat up, locally melting the solder. This localized heating, which works on the same principle as inductive stoves, remains completely contained, keeping the surrounding area cool. And second, the iron particles line up with the direction of the magnetic field, squeezing and pushing the liquid in that direction. This alignment is retained when the solder solidifies, and the well-ordered particles provide mechanical reinforcement that's greater than that afforded by a regular dispersion of particles."

Asus Takes Another Stab at Revolutionizing Netbook Market
Perhaps most well known for their netbook innovations with the Eee PC, Asus is at it again with their latest rollout at CeBIT Germany. The "Waveface Light," a new concept laptop, can be used as a conventional laptop or converted to a tablet by removing the keyboard and opening it to a completely flat position. Sounds like either a stroke of genius or a "small widget broke and now it's worthless" design issue.

Microsoft Spends $9 Billion On Research, Focuses On Cloud
superapecommando writes to share that Microsoft appears to be going all-out on research in the coming year, with a great focus on the cloud. They're supposedly planning to spend $9.5 billion in R&D; that's $3 billion more than the next-closest tech company. "'Especially in light of the tough difficult macroeconomic times that we're coming out of, we chose to really lean in and double down on our innovation,' [Microsoft COO Kevin] Turner said. Turner contended that Microsoft has more cloud services than any other company, ranging from its consumer email service to hosted enterprise products such as its Dynamics CRM (customer relationship management) system to its Azure cloud operating system. 'We're going to change and reinvent our company around leading in the cloud.'"

Jacobsen v Katzer Settled — Victory For F/OSS
Andy Updegrove writes "A short while ago the parties to one of the most closely watched FOSS cases filed a settlement agreement with the US Federal District Court for the Northern District of California ending one of the most important F/OSS legal cases to date. That case is Jacobsen vs. Katzer, and the settlement marks a complete victory for Jacobsen, a member of the Java Model Railroad Interface (JMRI) Project. Jacobsen's victory establishes several important rights for the first time in the US: the right to prevent their copyright and authorship acknowledgments from being removed from their code, and the right to collect damages if the terms of the licenses they choose are violated. Until now, those rights had never been tested in court."

New Linux-Based Laptop For Computer Newbies
Smivs writes "The BBC is carrying a report on how people confused and frustrated by computers can now turn to a laptop called Alex built just for them. Based on Linux, the laptop comes with simplified e-mail, web browsing, image editing and office software. Those who sign up for Alex pay £39.95 a month for telephone support, software updates and broadband access. The Newcastle-Based Broadband Computer Company who developed Alex has been working on this project for three years, and didn't immediately adopt a Linux solution — in fact, the first big trial was based on Windows. The company's Chief Technology Officer Barney Morrison-Lyons says that was never going to be the right route:
'The biggest problem with Microsoft is badly-written software — the operating system allows you to write software badly unlike Mac or Linux.'
Mr. Hudson, one of the company's founders, said the company also intends to launch an application store for Alex for customers who want to add more features and functions to their computer. 'People who love Linux will be keen to develop for this,' he said."

Google Buys iPhone Search App, Kills It
Hugh Pickens writes "PC World reports that Google has acquired a popular iPhone application called reMail that provides 'lightning fast' full-text search of your Gmail and IMAP e-mail accounts. The app downloads copies of all your e-mail which can then be searched with various Boolean options. reMail has only been in the application store for about six months — with a free version limited to one Gmail account and a premium version which can connect to multiple accounts. 'Google and reMail have decided to discontinue reMail's iPhone application, and we have removed it from the App Store,' writes company founder Gabor Cselle, who will be returning to Google as a Product Manager on the Gmail team. Google isn't saying what the fate of reMail might be. Some are suggesting reMail could be integrated into Gmail search or live on in some form as a part of Android, Google's mobile platform. Another possibility is that Google may have snapped up reMail just to kill it, not because reMail was a competitor to anything Google had, but because reMail made the iPhone better or the acquisition may have more to do with keeping good search technology away from the competition, as opposed to an attempt to undercut the iPhone. 'Perhaps Google is just planning to buy up all the iPhone developers, one at a time, until Android is the only game in town,' writes Bill Ray at the Register."

Opera Open Sources Dragonfly
netux writes to mention that Opera has released Dragonfly, their answer to Firebug, as an open source project under the BSD license. The release features a complete architectural overhaul using a modern version of the Scope Protocol (STP-1), a Mercurial repository on BitBucket, and a Wiki to get the ball rolling. "This is Opera’s first full open source project, so there will be a learning curve. We ask you to bear with us while we get everything up and running and policies in place. Coming from a closed source background there are some hurdles to overcome, such as the current bug tracking system being on a closed server. We hope to migrate to an open bug tracking system as the project gets on its feet."

What Knowledge Gaps Do Self-Taught Programmers Generally Have?
BeardedChimp writes "I, like many others here, have learned to program by myself. Starting at a young age and learning through fiddling I have taught myself C++, Java, python, PHP, etc., but what I want to know is what I haven't learned that is important when taught in a traditional computer science curriculum. I have a degree in physics, so I'm not averse to math. What books, websites, or resources would you recommend to fill in the gaps?"
