TiVo Unveiling New TV Recorder


With 1.9 million subscribers or less than half the 4-plus million it had in 2007, these have been difficult times for TiVo. But the struggling DVR pioneer is hoping there is still demand for its set-top boxes.

The company is about to unveil TiVo Premiere Elite, with four tuners that let you record up to four shows at once, plus 2 terabytes of storage, room for up to 300 hours of high-definition programming.

The $499 box is supposed to be available later this year, pending a Federal Communications Commission waiver (of a requirement to include analog tuners). Given the plunge in subscribers the lingering question is how many remaining on the service will be lining up by then to get one?

AMD A4-3300 and A4-3400 APUs ready to ship, take on Intel for your budget PC dollar


That's right folks, AMD's A4 APUs are here and ready to take on Intel in a battle for the bottom end of the mainstream desktop market. These dual-core desktop parts pack integrated graphics courtesy of the company's Radeon line. Both also boast a 65W TDP and 1MB of L2 cache. The only difference here is speed and price: the 3300 clocks in at 2.5GHz with a 440MHz GPU for $70, while the 3400 moves on up to 2.7GHz and a 600MHz GPU for only $5 more. They're not exactly speed demons, but should be able to hold their own against similarly priced Pentiums -- especially if you don't plan on buying a discrete graphics card. You can pick one up now at Amazon and other select retailers.

Asteroid Surfing Could Be The Best Way To Get To Mars


Getting to Mars is going to involve building a huge spacecraft and loading it up with tons of fuel and radiation shielding. Unless, we could just tag along with a spacecraft that's already headed in that direction, like an asteroid.

For an asteroid ferry to work, you'd have to be able to find a rock that's going to pass within a million miles or so of both Earth and Mars, which seems like a long shot. But, if you can wait until 2068, there will be two of them, both of which would drop you off close to Mars in under a year. The plan is pretty simple: just wait around in Earth orbit for the right asteroid to come by, jump on with all your gear, and then jump off again when it swings past Mars.

In addition to not having to, you know, build your own spaceship and stuff, asteroids also offer lots of radiation protection. This is important, since a round-trip voyage to Mars has the potential to increase cancer risk by up to 20% thanks to those nasty cosmic rays. In addition to being big and made of rock, space rocks would potentially have craters and caves that astronauts could hide out in, Millennium Falcon style. Just so long as they make sure it's actually a cave first.

Instead of just waiting around for a Mars-bound asteroid to randomly swing by Earth, another option is to just go wrangle an asteroid ourselves and push it where we want it to go. If we can get to one early enough, even a relatively small solar sail could provide enough thrust over time to nudge an asteroid into a useful Earth to Mars (or Mars to Earth) orbit. The eventual plan would be to stick one or more asteroids in permanent round-trip orbits, so you'd have a continual free ferry service from Earth to Mars and back.

Researchers From Harvard And MITRE Announce World's First Programmable Nanoprocessor


We've seen plenty of breakthroughs involving nanowires over the years, but none of those have involved an actual programmable processor -- until now, that is. That particular "world's first" was just announced by a team of researchers from Harvard University and the MITRE Corporation this week, and it's being described as nothing short of a "quantum jump forward in the complexity and function of circuits built from the bottom up." As for the processor itself, it consists of an array of nearly 500 germanium nanowires that have been criss-crossed with metal wires on a chip that's just 960 micrometers (or less than 1 millimeter) square. That becomes an actual processor when the researchers run a high voltage through the metal wires and switch the individual intersections off and on at will -- we're simplyfing things a bit, but you get the idea. What's more, the researchers note that the architecture is fully scalable, and promises to allow for the assembly of "much larger and ever more functional nanoprocessors." Head on past the break for the official press release.

Intel 'Not Blinking' On MeeGo, Nokia Workers In Protest


Nokia's decision to switch to Windows Phone for its devices has triggered harsh reactions both from Intel and within Nokia itself. Intel in a statement said it was "disappointed" with Nokia but said it was "not blinking" on supporting MeeGo. The chip designer said to Laptop it already supported other operating systems and that there were other platforms besides phones to support.

"We remain committed and welcome Nokia’s continued contribution to MeeGo open source," it said. "MeeGo is not just a phone OS, it supports multiple devices. And we’re seeing momentum across multiple segments -- automotive systems, netbooks, tablets, set-top boxes and our Intel silicon will be in a phone that ships this year."

The reference was likely to the Aava Core, an Atom-based phone developed by a startup.

Intel's loss of Nokia as a phone manufacturer is a major hit to its mobile plans in spite of its response. The company has been trying to reports from Finland have noted that hundreds of Nokia workers, possibly as many as 1,000, have walked out of Nokia's Tampere office in protest at the decision. Most of them are believed by HI to work on Symbian and are objecting to upcoming job cuts that will almost certainly scale back the software team as Nokia exits Symbian on smartphones.

The Tampere office was already expected to be closed, but over half of the 3,000 employees working there are involved in Symbian. Only the feature phone OS version, Series 40, is expected to survive in the long term. Some at the location also work on MeeGo and may see their involvement scale back.

Intel To Start Shipping B3 Stepping Cougar Point Chipset From February 14


Intel seems to have fast-tracked its Cougar Point chipset flaw rectification. The silicon giant claims that it will be in a position to start shipping B3 stepping of Cougar Point chipsets (Intel P67, H67, etc,) from 14 February, to OEM partners. According to the latest PCN (product change notification), number 110456-00 dated 2/9/2011, Cougar Point B3 will carry the following changes/features:

  • Revision ID will change from 04h to 05h
  • BIOS Update (Revision 1.1.4 of the BIOS Specification Update and Reference Code)
  • B3 stepping package is pin compatible with B2 stepping package
  • Minor metal layer change from B2 to B3 improving lifetime wear out with no changes to functionality or design specifications.
Of the above, the last bullet point affirms that the SATA 3 Gb/s port defect issue, which caused physical parts of the chipset to wear out abnormally fast, degrading performance, is resolved.

Crop Circles Theories


Out of nowhere, they seemingly appeared. Ring around the collar of an extraterrestrial nature that simply won’t go away. The intricate designs are discernible form the air, weirdly painted on the canvasses of corn fields. This phenomenon first started appearing in England and now is happening just about everywhere else around the world. What are they and where did they come from? What artist created them, what kind of brush did he use?

WHAT ARE THEY?
Crop circles are strange geometric designs carved in various fields and that have appeared throughout the years in rural farms. People continually insist these are the works of alien visitors from outer space or some other dimension.

The phenomena first appeared to be reported in England in the late 1970's.

Although two men, Dave Chorley and Doug Bower came forward in 1991 and claimed to have been making crop circles in England since the 1970s, many cereologists (crop circle enthusiasts) claim the designs and the technology needed to make them are for more complex than what a crew of humans could possibly have produced with mere planks, rope and wire. Moreover, some claim the intricate patterns are even difficult to reproduce with a computer.

These cereologists put forth paranormal or extraterrestrial explanations for the circles. Many theories abound; each one equally captivating in its own right.

HOW MANY ARE THERE?
About 10,000 crop formations have been reported globally since the late 70's. Hundreds have even been reported throughout the US. The first alleged US crop circle was reported in 1964.


A GREAT HOAX?
In 1991, more than a decade after the phenomenon really took off; Chorley and Bower, who both lived in Southampton, England proclaimed that the circles were an idea conceived as a prank. Allegedly, they were drinking buddies at a pub near Winchester, Hampshire and it was during an evening in 1976 over drinks, that the idea for creating these circles first occurred to them.

Inspired by the 1966 Tully Saucer Nests, Bower and Chorley claimed to have made their crop circles using planks, rope, hats and wire. They went on to explain they used a four-foot-long plank attached to a rope, which they said allowed them to easily create circles, some at least eight feet in diameter. As proof, the two men were able to make a 40-foot circle in 15 minutes.

However, the pair became frustrated when their work did not receive significant publicity, so in 1981 they created a circle in Matterley Bowl, a natural amphitheatre just outside Winchester , Hampshire. This area is surrounded by roads from which a clear view of the field is available to drivers; an ideal spot to impress anyone driving by.

Their designs were at first simple circles. Bower and Chorley made more complex patterns to drive the point home that indeed human hands were more than capable of creating such baffling field art.

So why would they finally admit to making them after pulling their hoax off successfully for so many years? The answer, Bower claimed, was extra-marital rather than extraterrestrial.

Bower's wife had become suspicious of him, noticing high levels of mileage in their car. She soon suspected him of adultery. At last Bower confessed to her. Shortly thereafter, he and Chorley informed a British national newspaper that they were behind the mysterious circles.

HOAX METHOD
Chorley detailed his technique as such: simple wire with a loop, hanging down from a cap - the loop positioned over one eye. This eye could be used to focus on a landmark to aid in the creation of straight lines. However, later designs of crop circles became dramatically more complicated and it would seem more detailed tools would be needed.

Chorley died in 1996, and Doug Bower has made crop circles as recently as 2004. Bower has said that, had it not been for his wife's suspicions, he would have taken the secret to his deathbed, never revealing that it was a hoax.

EXOTIC THEORIES
It is hard to fathom that a crew of humans could make these spectacular sights unnoticed by anyone else. This has been one of the underlining arguments in support of more exotic theories as to the origin of crop circles. We present some of the more common theories below:

Aliens
Author Colin Andrews published a book entitled Crop Circles, Signs of Contact. In it, he concluded that approximately 80% of all crop circles investigated in England from 1999-2000 were man made. He felt this was one of the most important research findings to date because it boiled it down to one amazing fact: the remaining 20% of crop circles showed no sign of human creation. His conclusion then called for an extraterrestrial source for the circles.

This claim has been contested by the Committee for the Scientific Investigation of Claims of the Paranormal (CSICOP), a world-wide organization that encourages the critical investigation of paranormal and fringe-science claims from a responsible, scientific point of view.

CSICOP notes that some of the alleged 20% of the so-called “genuine” crop circles have been documented as man-made. CSICOP alleges there is no reliable criterion for distinguishing between “genuine” crop circles and those that are man-made hoaxes. CSICOP is today known as CSI. So, in the end, CSICOP asserts there is no way to prove beings from outer space made them, at least scientifically.

Relation to Nazca Lines
The Nazca Lines are a series of geoglyphs located in the Nazca Desert, a high arid plateau that stretches 53 miles or more than 80 kilometers between the towns of Nazca and Palpa on the Pampas de Jumana in Peru.

These bizarre lines were created by the Nazca culture between 200 BC and 700 AD. There are hundreds of individual figures, ranging in complexity from simple lines to stylized hummingbirds, spiders, monkeys and lizards. The most amazing fact about them is that they cannot be recognized on the ground, only from the air.

Since it is presumed the Nazca people could never have seen their work from this vantage point, there has been much speculation on the builders' abilities and motivations. Were they sending messages to the heavens, communicating with extraterrestrials? Maybe the extraterrestrials made them to communicate with the Nazca culture? Could it be that crop circles are merely an updated version of Nazca phenomena? There is no evidence, but there are clearly some eerie similarities.

Plasma Vortices
One research scientist holds that “columns of ionized air” swoop down like little mini-tornados. It is these anomalous events that create the shapes in the crops.

Dr. W.C. Levengood, who published the paper, Anatomical Anomalies In Crop Formation Plants believes what is creating the crop circle is a complex energy system that he describes as a "spinning plasma vortex" of ions with microwave frequencies that rapidly heat water in plants, causing them to collapse to the ground with stems not cracked or broken.

Further, the microwave frequencies can heat up water in the plant's growth nodes which burst out, creating small holes that have often been found in extraordinary crop patterns. Those complex energies can also affect the seeds. Dr. Haselhoff never actually mentions where these supposed vortices come from or why they even exist.

Manifestations of Dreams
Joseph E. Mason believes our dreams have something to do with the formation of crop circles.

His extensive experience with dreams and meaningful coincidences is all part of the story. He believes that the crop circle formations are related to our collective unconscious.

Whereas most serious researchers favor the theory that the formations are, for the most part, manmade or the work of aliens, Mason believes crop circles may well be “a function of the collective unconscious of mankind,” as opposed to actual physical entities from another solar system.

Could our minds really have that kind of power?

Great Balls of Light
The Deepening Complexity of Crop Circles, by Dr. Eltjo H. Haselhoff, was the first popular scientific book about the world-wide appearance of crop circles.

Below are some statements that Dr. Haselhoff has made concerning crop circles:

“The complexity of the crop circle phenomenon is tremendously underestimated… because its true nature is unknown to the general public. Obviously, there are people trying to imitate the real thing, but the suggestion that these entire crop formations are made by men with simple flattening tools is by far insufficient to explain the well-documented observations.”

Dr. Hasselhoff claims those observations include “unambiguous and consistent biophysical anomalies” in the flattened plants, inside the circles, all of which have been published in peer-reviewed scientific literature.

Along with the increasing number of crop circle events, there are also a growing number of eyewitnesses, who claim to have seen how crop circles appeared before their eyes in just a few seconds.

If they are to be believed, several of these people say that bright, “fluorescent balls of light” hovered above the fields at the time circles magically formed before their eyes.

“After some straightforward research, it was discovered that the plant stems inside these formations had increased in diameter, as an effect of intensive heating, with an astonishing circular symmetry,” reported Dr. Haselhoff.

This effect perfectly matched the radiation pattern of an electromagnetic point source at a height of four meters and ten centimeters above that field, Dr. Haselhoff said.

Dr. Haselhoff claims this is solid physical evidence that these eyewitnesses spoke the truth. Dr. Haselhoff applied this analysis to other crop circles, which had been investigated by others in the past. He claims to have obtained identical results.

Curiously, his analysis failed dramatically on several man-made crop circles. The logical conclusion is that “balls of light” must indeed be involved in the creation of crop circles.

He submitted his findings to the international and peer-reviewed scientific journal Physiologia Plantarum, a plant biology journal, where the article was eventually published.

“This has important consequences,” Dr. Haselhoff would later claim. “The hypothesis that these balls of light are involved in the creation of crop circles is now no longer just a hypothesis, but a scientifically accepted fact.”

Dr. Haselhoff's findings are in perfect agreement with the opinion of the American researchers John Burks, Levengood and Nancy Talbot – the famous BLT Team. They suggested in two other scientific articles that the plant alterations in crop circles were the result of electromagnetism.

Naturally, the trio, like other crop circle enthusiasts, has been attacked by skeptics.

Dr. Haselhoff sums up his feelings on crop circles:

“Something very strange is going on. No-one can deny this. Anyone who claims the opposite clearly does not know what he is talking about… I consider it the duty of every scientist to figure out what on earth is going on.”

THE SKEPTICS
The main criticism of alternative theories is that evidence of paranormal origins, alleged eyewitness testimony aside, is relatively scant. Crop circles are easily explained, the skeptics say, as the result of pranksters.

In fact, numerous cases have been documented where researchers declared crop circles to be "the real thing." However, all too soon they are confronted with the hoaxers who created the circle. Another damning fact is the media coverage effect.

As media coverage of the crop circles increased throughout the 1980’s and 1990’s, the frequency at which crop circles appeared also increased, as well as the number of locations they were sighted in. This leads many to believe that the creation of crop circles is a ‘copy-cat’ activity. After all, would aliens increase the frequency of creating crop circles due to greater media coverage? Not likely, it would seem.

THE CONCLUSION
The answer to the mystery of crop circles is still a perplexing one. Be it in the deep inner reaches of outer space or within the mysterious workings of human psychological projection, the real source is unknown. However, whether they be balls of light or messages from beings of higher intelligence, they all appear to happen with enough frequency to people that would throw doubt to the hoax theory. Additionally, it seems hard to believe that men with simple rope contraptions could create some of the complex patterns that are even difficult to replicate on paper with a protractor and compass.

We must consider then:
If a race from another part of the galaxy wanted to communicate, would they do so by using our crop fields as some kind of canvas to communicate? We have to be especially aware that many believe that mathematics will lead us to language that may allow us to communicate to other lifeforms that are extraterrestrial in nature.

As we stand on the threshold of a brave new world, as space exploration continually progresses in its quest to answer the mysteries of the universe we would be remiss to neglect the mysteries right in our very own crop fields. We need to encourage further exploration of the crop circle riddle. Maybe one day the mystery of crop circles will be answered but until then it appears crop circles will baffle us for some time.

Flood Formed Giant Martian Sinkhole


LIKE water draining from an unplugged bathtub, meltwater flowing through deep cracks in the Martian rock may explain the origins of the enormous Hebes Chasma canyon.

About 100,000 cubic kilometres of material had to be removed to form the scar, which is five times the width and depth of the Grand Canyon. But where that material went has been a mystery, as there are no surface channels through which water and sediment could have exited.

John Adams of the University of Washington in Seattle and colleagues proposed in 2009 that heat from magma beneath the surface caused ice held in the rock to melt and released water locked up in salts. The water then drained away through underground cracks, leaving a void into which the overlying rock collapsed, to form the canyon.

Now, a tabletop experiment has bolstered this theory. Martin Jackson of the University of Texas at Austin and colleagues filled a box with viscous silicone oil, representing a watery slush, and covered it with sand and small glass spheres. As the oil was allowed to drain out through slits in the box's floor, a structure resembling Hebes Chasma appeared (Geological Society of America Bulletin, DOI: 10.1130/B30307.1).

Water from the canyon may have erupted onto the surface again. This would account for a nearby valley called Echus Chasma that looks as if it was carved by water, but for which there is no other obvious source. "You've got signs that a huge amount of water just erupted out of nowhere from depth and flowed down, scouring out a valley," Jackson says.

Similar collapses might have helped form other giant canyons on Mars, perhaps including Valles Marineris, the solar system's largest, though other factors like tectonic stretching were likely involved too, Jackson says.

Asteroid Makes Sharpest Turn Yet Seen In Solar System


On Friday, a metre-sized asteroid called 2011 CQ1 was spotted zipping only 5480 kilometres above the Earth's surface. That is the closest near miss on record, beating the previous record holder, a rock that buzzed Earth in 2004 called 2004 FU162, by a few hundred kilometres.

When something that small comes close to our planet, Earth's gravity is sure to bend its orbit. In this case, the approach was so close that the little asteroid's path bent by 60 degrees, reports Don Yeomans of NASA's Jet Propulsion Laboratory in Pasadena, California.

Short of collisions with a planet, that's the biggest orbital change ever recorded by observers. It was large enough to shift the asteroid from one category of objects into another. As Yeomans and his JPL colleague Paul Chodas explain in an online update:
Prior to the Earth close approach, this object was in a so-called Apollo-class orbit that was mostly outside the Earth's orbit. Following the close approach, the Earth's gravitational attraction modified the object's orbit to an Aten-class orbit where the asteroid spends almost all of its time inside the Earth's orbit.
Gravitational encounters between objects large and small have been rearranging the solar system since it formed some 4.56 billion years ago. We now believe even planets have been shuffled in their orbits. In this case, we had the good fortune to spot a very large change in the orbit of one very small object around the sun.

But now that 2011 CQ1 has had its 15 minutes of fame, we are unlikely to spot the small, dim object again, says Emily Lakdawalla of the Planetary Society, a space advocacy group in California: "We'll probably never be close enough to it again to be able to pick its dim light out from the background of stars."

Activision Ends Guitar Hero And True Crime Franchises


The music game genre helped many musicians get back into the mainstream and titles like Guitar Hero and Rock Band were some of the strongest selling franchises for game publishers in years past. Apparently, the strong sales of music games have ended for Activision.

The company has announced that Guitar Hero is no more. The company has stopped development on the game franchise and will disband the Guitar Hero business unit and discontinue all development on titles in the franchise for 2011.

The game publisher blames the killing of the Guitar Hero brand on declines in the music game genre. Guitar Hero isn’t the only previously very popular franchise to get the axe, development on True Crime: Hong Kong has also been stopped.

MySpace For Sales


In an earnings call Wednesday, News Corp. officially stated it plans to sell MySpace. During the call, COO Chase Carey said that "now is the right time" to attempt to place the social network "under a new owner."

MySpace has undergone drastic changes in the past year, including a ground-up redesign, total repositioning as a media company rather than a social network per se, renegotiation of its advertising deal with Google (a key part of the site's revenue), and a staff shuffling that saw more than one key executive relocating to a new venture.

Moreover, almost half of MySpace's staff was served pink slips at the beginning of 2011, further reducing overhead.

Yet, in spite of these changes, News Corp. said in today's call that the parent company isn't entirely pleased with the results. Ad revenues are lower than they once were, and "results at MySpace have been below our expectations," a company rep said.

"The new MySpace has been very well received by the market, and we have some very encouraging metrics," Carey said. "But the plan to allow MySpace to reach its full potential may be best achieved under a new owner."

The MySpace renovations have not been cheap for its parent company. In its earnings statement, News Corp. said that while cable and broadcasting revenues are solid, the company "recorded a $275 million pretax charge for the impairment of goodwill related to the Digital Media Group and an organizational restructuring at MySpace."

Rumors of MySpace's eventual sale to an entity outside the News Corp. family have been swirling for some time. But Carey's confirmation in today's call suggests News Corp., which bought MySpace in 2005 for $580 million, would prefer that sale to happen sooner rather than later.

MySpace has been, as far as digital properties are concerned, a fixer-upper; and News Corp. has done a lot to fix it up. But are the site's repositioning, reorganization and redesign enough to make it a good buy for another entity? We're as curious as anyone to learn how this saga will conclude and what will become of MySpace once its News Corp./Fox Digital era comes to an end.

Google Invites You To Crack Their Chrome


Last year, after two full days of hacking, only one web browser emerged from Pwn2Own unscathed: Google Chrome. IE8, Safari 4, Firefox 3, and even Safari on iOS actually all fell after just one day, but no one could seem to penetrate Chrome. In fact, despite a $10,000 bounty to crack their “sandbox”, no one even tried, likely figuring it was futile. And so this year, Pwn2Own wasn’t even going to invite Chrome back. Then Google stepped in with wads of cash.

While the lineup for Pwn2Own 2011 was announced a few days ago, Google took the time today to give a bit more details about their role in the event. Of note, they write: “Chrome wasn’t originally going to be included as a target browser in the competition, but Google volunteered to sponsor Chrome’s participation by contributing monetary rewards for Chrome exploits.”

In other words: bring it, hackers.

Specifically, Google worked with the conference to come up with rules for hacking the code found in Chromium (the open source browser on which Chrome is based). On day one, if anyone is able get nail a working exploit of Chrome (again, cracking the sandbox), Google will pay them $20,000. On day two and three, the same $20,000 will be paid out for “bugs in the kernel, device drivers, system libraries, etc,” but Google and the conference will split the cost of that reward (since Google says it cares more about the first variety).

It says a lot that Chrome was the one browser not hacked last year. It says even more than this year they’re sponsoring their own participation and doubling the reward. But it’s standard business now for Google to dish out cash rewards for people who find issues with their browser. And it’s a really smart idea.

One thing Google does note is that Chrome OS, which is built with Chrome, is not a part of this competition. Because it’s still “beta” software, Google apparently doesn’t feel confident enough in it yet for it to stand up to the hackers.

Hackers Could Track The Person Behind Your Usernames


A new wave of online crime is on the way – and all that's required is your username. Hackers may soon be able to identify which screen names belong to one person just by analysing the characters that make up the name.

This would allow criminals to send out better-targeted spamming and phishing attacks. For instance, cross-referencing eBay usernames with Google email accounts could allow accurately targeted phishing attacks, using freely available data about a user's eBay purchasing habits.

"I don't think it would be hard to pull off such an attack," says Daniele Perito at the National Institute for Computing and Automation Research, in Grenoble, France, the lead author of the work.

"Usernames are like digital fingerprints – on a given service, they are the only pieces of information that have to be unique," explains Patrick Fitzgerald of internet security company Symantec Security Response. But even though they are so specific, extra information, such as a date of birth or location, is usually required before multiple names can be pinned to a single user.


Now Perito and colleagues have studied how usernames alone can identify a person. The team took almost 10 million usernames from Google, eBay and MySpace, and used statistical analysis to create a tool that calculates how unique a username is. Unsurprisingly, they found that names owned by an individual tend to be extremely similar.

From there, they developed a method for cross-referencing usernames across different sites. By analysing the text that makes up usernames, how different they are to each other, and how likely it is that a user chooses a particular set of names, they're able to accurately match multiple names to a single physical user.

"The tool can find linked usernames 50 per cent of the time with almost absolute accuracy," says Perito. The technique only gets caught out when users deliberately choose disparate names. "But users tend to choose and change their usernames in predictable ways, and they tend to have a small set of distinct usernames," explains Perito.

The technique could be used by scammers who would be able to create a detailed profile of what you buy online, and what sites you visit.

"It's interesting research," says Fitzgerald. "If these techniques were extended… then far more sophisticated profiles [than available at present] could be created."

"But the ultimate risk is the information that people freely give away," he warns – personal details that go far beyond usernames. "People need to think about the consequences of sharing their lives on the internet."

Facebook Co-Founder Opens The Curtain On Two-Year Old Asana


Two years ago, when Dustin Moskovitz announced he was leaving Facebook to start a new company with fellow-Facebooker Justin Rosenstein most people thought one of two things: He’d had a falling out with Mark Zuckerberg or he was just crazy. What could be more exciting than Facebook?

Moskovitz was Zuckerberg’s college roommate and co-founder of Facebook. If you get your Facebook history from Aaron Sorkin, he was the guy coding away in silence while half-naked girls did bong hits. If you get your Facebook history from, you know, things that actually happened, Moskovitz outlasted any other co-founder and easily played one of the most pivotal roles in the company’s early years. As such, Asana will get more attention and scrutiny and maybe even hype than most business software startups.

But here’s the thing: Asana deserves it. As it turns out neither of the suppositions for Moskovitz’s decision to leave were right. Moskovitz and Rosenstein just had a really big idea: To fix how people collaborate on projects and work in teams. Something that has so far been unfixable despite billions spent on developing and implementing collaboration and communication software. Something that may be so rooted in the idiosyncrasies of human behavior that it may not be fixable.

But Asana’s opening salvo is pretty impressive. There’s a full demo of the software in the video below, from Asana’s recent friends-and-family open house, so I won’t belabor the features and screen shots here. Hear the pitch from the founders yourself. The company is still in private-beta, and it has a 1,200-company waiting list to get an invite. It’ll be opening up more over the course of this year. Asana has raised just over $10 million from several angels, Benchmark Capital and Andreessen Horowitz.

Asana

Asana builds enterprise-level collaboration software, or a Collaborative Information Manager. It was founded by Dustin Moskovitz, a co-founder of Facebook, and Justin Rosenstein, an alum of both Facebook and Google.

For their software, Asana is developing an in-house programming language called Lunascript for writing rich web applications more efficiently.

Asana has received considerable backing from Andreessen-Horowitz, Benchmark Capital, and a number of angel investors.

The Winners Of The 'Game On' Open Web Gaming Competition Already Announces By Mozilla


Mozilla's Game On competition came to an end and it's time to meet the winners. Though there were plenty of entries, the jury ended up with several games which excelled in one particular aspect and one that was deemed best overall. They each have their strengths and weaknesses, but all have one thing in common, they're a lot of fun. 

The Game On competition is run by the Mozilla Labs Gaming initiative which encourages games built with open web tools and based on open technologies.

The first edition of the Game On competition has now ended, after several months of submissions and a few weeks of review, and the winners have been announced.

The best overall game is MARBLE RUN, a game in which you have to design the longest marble run you can within the limited space and with the blocks available to you.

The interesting part is that, while the game offers an individual experience, the overall goal is to tie together all of the designs to create the largest marble run in existence.


The best technology award went to Far7, a space MMORPG. It makes heavy use of HTML5, specifically the Canvas element, SVG for animations, and WebSockets for communications, you couldn't ask for a more complete showcase of what modern web technologies can do.

Mozilla's judges have also chosen winners in the Best Aesthetics, Most Original, Most Polished and Most Fun Categories. You can check out the winners' gallery here.

The community award went to Z-Type, a very original and addictive game that has proven quite popular lately. So popular in fact that so many users played it for so long they uncovered a critical security flaw in Google Chrome, which has been fixed in the latest stable release.

All the winners took home quite a few prizes, but perhaps the exposure they got from being picked by Mozilla was the biggest prize of all. As for those looking to kill a few minutes, or a few hours, they'll probably find something they like among the winners or even among the other submissions.
