Submission + - Users abandon ship if online video quality is not up to snuff, says study (umass.edu)

An anonymous reader writes: The first large scientific study of how people respond to poor video quality on the Internet paints a picture of ever rising user expectations and the willingness to abandon ship if those expectations are not met.

Some nuggets...
1) Users are willing to wait for no more than 2 seconds for a video to start playing, with each additional second adding 6% to the abandonment rate.
2) Users with good broadband connectivity expect faster video load times and are even more impatient than ones on mobile devices.
3) Users who experience video freezing watch fewer minutes of the video than someone who does not experience freezing. A 1% freezing causes 5% less minutes watched.
4) Users who experience failures when they try to play videos are less likely to return to the same website in the future.

BIG data analyzed (260+ million minutes of video) and some cool new data analysis techniques used.

8-Year-Olds Publish Scientific Bee Study 174

flintmecha writes "A group of British schoolchildren may be the youngest scientists ever to have their work published in a peer-reviewed journal. In a new paper in Biology Letters, children from Blackawton Primary School report that buff-tailed bumblebees can learn to recognize nourishing flowers based on colors and patterns. The paper itself is well worth reading. It's written entirely in the kids' voices, complete with sound effects (part of the Methods section is subtitled, ''the puzzle'duh duh duuuhhh') and figures drawn by hand in colored pencil."

Gamer Plays Doom For the First Time 362

sfraggle writes "Kotaku has an interesting review of Doom (the original!) by Stephen Totilo, a gamer and FPS player who, until a few days ago, had gone through the game's 17-year history without playing it. He describes some of his first impressions, the surprises that he encountered, and how the game compares to modern FPSes. Quoting: 'Virtual shotgun armed, I was finally going to play Doom for real. A second later, I understood the allure the video game weapon has had. In Doom the shotgun feels mighty, at least partially I believe because they make first-timers like me wait for it. The creators make us sweat until we have it in hand. But once we have the shotgun, its big shots and its slow, fetishized reload are the floored-accelerator-pedal stuff of macho fantasy. The shotgun is, in all senses, instant puberty, which is to say, delicately, that to obtain it is to have the assumed added potency that a boy believes a man possesses vis a vis a world on which he'd like to have some impact. The shotgun is the punch in the face the once-scrawny boy on the beach gives the bully when he returns a muscled linebacker.'"

Submission + - When mistakes improve performance (bbc.co.uk)

jd writes: "Professor Rakesh Kumar at the University of Illinois has produced research showing that allowing communication errors between microprocessor components and then making the software more robust will actually result in chips that are faster and yet require less power. His argument is that at the current scale errors in transmission occur anyway and that the efforts of chip manufacturers to hide these to create the illusion of perfect reliability simply introduces a lot of unnecessary expense, demands excessive power and deoptimises the design. He favors a new architecture, which he calls the "stochastic processor" which is designed to gracefully handle data corruption and error recovery. He believes he has shown such a design would work and that it will permit Moore's Law to continue to operate into the foreseeable future. However, this is not the first time someone has tried to fundamentally revolutionize the CPU. The Transputer, the AMULET, the FM8501, the iWARP and the Crusoe were all supposed to be game-changers but died a cold, lonely death instead — and those were far closer to design philosophies programmers are currently familiar with. Modern software simply isn't written with the level of reliability the Stochastic Processor requires in mind (and many software packages are too big and too complex to port), and the volume of available software frequently makes or breaks new designs. Will this be "interesting but dead-end" research, or will the Professor pull off a CPU architectural revolution really not seen since the microprocessor was designed?"

Drifting Satellite Could Knock Out Cable TV 217

A few days back we discussed some of the problems caused by the demise of Intelsat's Galaxy 15, including possible degradation of GPS and its WAAS refinement. Now reader crimeandpunishment writes in with another damage scenario, one which could affect vastly more people — interference with cable TV programming across the US. "A TV communications satellite is drifting out of control thousands of miles above the Earth, threatening to wander into another satellite's orbit... Galaxy 15 continues to receive and transmit satellite signals, and they will probably interfere with the second satellite, known as AMC 11, if Galaxy 15 drifts into its orbit as expected around May 23... [A spokesman] said one option would be using AMC 11's propulsion system to shift that satellite about 60 miles (100 kilometers) away to an orbit that's still within its carefully prescribed 'orbital box' but as far away as possible from Galaxy 15."

The Humble Indie Bundle 290

supersloshy writes "Last year, 2D Boy, the developers of the popular independent game World of Goo, had a pay-what-you-want birthday sale with curious results. For the next seven days, Wolfire Games is attempting the same kind of sale, but with some new twists. Wolfire Games' Humble Indie Bundle contains five independent games (World of Goo, Aquaria, Gish, Lugaru HD, and Penumbra) with no DRM and they are all cross-platform. In addition to directly supporting the developers of these five games, part of the money also goes to the Electronic Frontier Foundation and the Child's Play Charity. No matter how much you spend, you also get to choose who your money goes to (charity only, developers only, evenly, or custom)."

The Virtual Choir Project 58

An anonymous reader writes "Conductor and composer Eric Whitacre has successfully created a virtual choir using the voices of 185 people who posted their performance on YouTube. The piece that's performed is called 'Sleep,' composed by the conductor himself in 2000. Anyone can join in — all you need is a webcam and a microphone."
