Visual Studio 2010 is a fairly important release of the developer tool of choice for writing Windows applications. One of the important advancements in the new update is how it enables developers and architects to better visualize the assets and dependencies through UML (Unified Modeling Language) diagrams. In this episode, Cameron Skinner gives us a quick overview of how Visual Studio 2010’s new UML visualization tool's design might help you with better understanding the overall structure of your applications.

William Bell may currently be stuck Over There, but he could soon be Over and Out. According reports, Leonard Nimoy is set to retire from acting – but when, and what does this mean for his part on Fringe? Head past the jump to find out. Warning, we feel that his retirement will be general knowledge, but the details of which are below the jump for a reason -  do not click link if you don’t want to know the details! In an interview with Toronto Sun, Leonard Nimoy revealed he will be bringing the curtain down on his 60 year acting career. Having just shot his final appearance as William Bell for the Fringe Season 2 finale, Nimoy says he plans to “go out on a positive note”.

Dr. Cormac Herley spends most of his time thinking about why and how computer users reject security advice (originating from both fellow humans and software security warning prompts). Recently, his paper So Long, and No Thanks for the Externalities: the Rational Rejection of Security Advice by Users, received a fair amount of attention from the general media (Boston Globe, Tech Republic, NPR, etc). The paper also prompted our favorite software renegade, Dr. Erik Meijer, to send me an email simply asking "please set up and E2E with Cormac Herley". I did just that and the following conversation is what happened...

Part 2 of an excerpt from the book "Acoustics and Psychoacoustics", 4th edition, looks at acoustic and psychoacoustic principles applied to the clinical measurement of hearing ability, as well as procedures used in psychoacoustic testing.

Part 1 of an excerpt from the book "Acoustics and Psychoacoustics", 4th edition, examines the ways to make rooms better for the purpose of critically listening to music.

How's this for a wedge issue on a slow news week? When Xilinx announced earlier this year that it was changing one of its foundry suppliers from UMC to TSMC for the 28-nm node, it seemed like a blow to differentiation—at least from a process technology standpoint—between Xilinx and Altera, which has been using TSMC for years. But while Xilinx chose to go with TSMC's high-performance/low power process, Altera said this week it is going with TSMC's high-performance process. Altera maintains that customers in the high end communications equipment market are much more concerned about performance than power. Luanne Schirrmeister, senior director of product marketing at Altera, put it this way: "In communications infrastructure, nothing is battery powered. Everything is plugged into a wall."

Catalan researchers have discovered in the rubbish dump of Can Mata in the Vallès-Penedès basin (Catalonia) a new species of Pliopithecus primate, considered an extinct family of primitive Catarrhini primates (or "Old World monkeys"). The fragments of jaw and molars found in this large site demonstrate that Pliopithecus canmatensis belongs to this group, which includes the first Catarrhini that dispersed from Africa to Eurasia.

Carved in stone on a Civil War-era bridge -- a world-class feat of engineering that stands a couple miles northwest of Washington -- are the names of builders and officials of the day.

A key name, however, is missing. New research shows that Virginian Alfred R. Rives led the design and construction of the Cabin John Bridge. Also called the Union Arch Bridge, the aqueduct and roadway reaches 220 feet across Cabin John Creek in a single span -- the world's longest single-span masonry bridge for nearly 40 years and the nation's longest still today.

A new triple-rate (3G/HD/SD) audio/video clock generator from National Semiconductor Corp., eliminates the need for external clock conditioning in professional and broadcast video equipment. The LMH1983 produces all the major video and audio reference clocks required for a broad range of applications. The highly integrated LMH1983 also provides the industry’s lowest-output jitter (40 ps peak-to-peak), enabling Society of Motion Picture and Television Engineers (SMPTE) compliance using field-programmable gate array (FPGA) SerDes transceivers.

Researchers at North Carolina State University have developed a new approach to software development that will allow common computer programs to run up to 20 percent faster and possibly incorporate new security measures. The researchers have found a way to run different parts of some hard-to-parallelize programs — such as word processors and web browsers — at the same time, which makes the programs operate more efficiently.

This week, Mercury is emerging from the glare of the sun and making a beeline for Venus. By week's end, the two planets will be just 3o apart, an eye-catching pair in the deep-blue twilight of sunset. The best nights to look are April 3rd and 4th. Go outside at the end of the day and face west. Venus pops out of the twilight first, so bright it actually shines through thin clouds. Mercury follows, just below and to the right: April 3April 4 Venus is an old friend to most sky watchers; Mercury, less so. The first planet from the sun spends most of its time wrapped in painful sunlight. Seeing it so easily, and in the beautiful company of Venus no less, is a rare treat indeed. The next apparition this good won't come until Nov. 2011. By that time, however, we'll have much better view of Mercury all the time. NASA's MESSENGER probe is en route to Mercury now, and in March of 2011 it will become the first spacecraft to orbit the planet. During a year-long science mission, MESSENGER will beam back a stream of high-resolution pictures and data obtained using seven instruments designed to operate in the extreme environment near the Sun. This kind of coverage of planet #1 is unprecedented.

Imagine you're a Brontosaurus1 with your face in a prehistoric tree top, munching on fresh leaves. Your relatives have ruled planet Earth for more than 150 million years. Huge and strong, you feel invincible. You're not. Fast forward about 65 million years. A creature much smaller and weaker dominates the Earth now, with brains instead of brawn. Its brain is a lot larger relative to its body size – plenty big enough to conceive a way to scan the cosmos for objects like the colossal asteroid that wrought the end of your kind. Right: An artist's concept of NASA's Wide-field Infrared Survey Explorer (WISE). [more] The creature designed and built WISE, NASA's Wide-field Infrared Survey Explorer, to search for "dark" objects in space like brown dwarf stars, vast dust clouds, and Earth-approaching asteroids. WISE finds them by sensing their heat in the form of infrared light most other telescopes can't pick up.

March 19, 2010: When the sun sets on Saturday, March 20th, a special kind of night will fall across the Earth. It's an equal night. Or as an astronomer would say, "it's an equinox." It's the date when the sun crosses the celestial equator heading north. Spring begins in one hemisphere, autumn in the other. The day and night are of approximately equal length. To celebrate the occasion, Nature is providing a sky show. It begins as soon as the sky grows dark. The Moon materializes first, a fat crescent hanging about a third of the way up the western sky. Wait until the twilight blue fades completely black and you will see that the Moon is not alone. The Pleiades are there as well. The Moon and the Pleiades are having a close encounter of rare beauty. There's so little space between the two, the edge of the Moon will actually cover some of cluster's lesser stars. According to David Dunham of the International Occultation Timing Association, this is the best Moon-Pleiades meeting over the United States until the year 2023. Right: A similar Moon-Pleiades conjunction photographed by Marek Nikodem of Szubin, Poland, in July 2009.

Power and energy are key design considerations across a spectrum of computing solutions, from supercomputers and data centers to handheld phones and other mobile computers. A large body of work focuses on managing power and improving energy efficiency. While prior work is easily summarized in two words—"Avoid waste!"—the challenge is figuring out where and why waste happens and determining how to avoid it. In this article, I discuss how, at a general level, many inefficiencies, or waste, stem from the inherent way system architects address the complex trade-offs in the system-design process. I discuss common design practices that lead to power inefficiencies in typical systems and provide an intuitive categorization of high-level approaches to addressing them. The goal is to provide practitioners—whether in systems, packaging, algorithms, user interfaces, or databases—a set of tools, or "recipes," to systematically reason about and optimize power in their respective domains.

ALSOK, a security firm that specializes in robot guards, has sent their drones into shopping malls, office buildings, and museums.  This video shows one of them patrolling an art gallery.  Not surprisingly, even in Japan, the sight of a robot patrolling its beat is more than enough to distract some of the visitors from the actual works of art!
