Pixar Is Inventing New Math

Pixar Is Inventing New Math:

According to DeRose, Pixar is the first Hollywood studio equipped with it’s very own in-house scientific research facility. Mathematicians and computer scientists there are figuring out new mathematical ways to solve problems in animation.

What they’re finding is that the interplay between academics and industry has been hugely successful. According to DeRose they now have more courage to explore scientific musings that would normally only have been possible in a university environment.

VirtuSphere

VirtuSphere

The VirtuSphere platform consists of a large hollow sphere that sits on top of a base and allows the sphere to rotate 360 degrees. Wearing a wireless, head-mounted display, users can step inside the sphere to fully interact in immersive virtual environments. The VirtuSphere enables 6 degrees of freedom – one can move in any direction; walk, jump, roll, crawl, run over virtually unlimited distances without encountering real-world physical obstacles.

VirtuSphere systems are made to client specifications and typically include an easy-to- assemble sphere, a base platform that enables it to rotate, a head-mounted display, 3D sensors, sphere rotation trackers, a computer, device drivers and 3D software applications.

Digital Pen

Digital Pen

Cool gadget –Logitech io2 Digital Pen. Take notes on paper and then dock the pen in your computer and have the notes captured in your computer. It can convert your handwriting to digital text as though you typed it in. You can also import drawings and sketches from the pen as jpg, gif, png etc. files. It seems the pen only works with their paper which seems like a bad design for customers, but those interested in gadgets might like it.

Cost of Powering Your PC

The cost of leaving your PC on

Have you ever wondered how much it’s costing you to leave a computer on 24 hours a day, 7 days a week?

Here’s the kilowatt-hour calculation for my server, which draws ~160 watts: 160 watts * (8,760 hours per year) / 1000 = 1401.6 kilowatt-hours

The other thing you’ll need to know is how much you’re paying for power in your area. Power here in California is rather expensive and calculated using a byzantine rate structure. According to this recent Mercury News article, the household average for our area is 14.28 cents per kilowatt-hour. 1401.6 kilowatt-hours * 14.28 cents / 100 = $200.15 So leaving my server on is costing me $200 / year, or $16.68 per month. My home theater PC is a bit more frugal at 65 watts. Using the same formulas, that costs me $81 / year or $6.75 per month.

Power could cost more than servers, Google warns: “A Google engineer has warned that if the performance per watt of today’s computers doesn’t improve, the electrical costs of running them could end up far greater than the initial hardware price tag.”

IBM Believes New DRAM will Double Performance

IBM drives road to denser CPU memory

By combining techniques in process and circuit design, IBM believes it can put as much as 48 Mbytes of fast DRAM on a reasonably sized CPU when its 45nm technology becomes available in 2008.

BM combined two advances to enable the new memory integration. The company found a way to migrate its deep trench technology used for DRAMs from CMOS to its silicon-on-insulator (SOI) logic process. In a paper last December, IBM described that work that involved suppressing the floating-body effect in SOI.

Biocomputing with Martyn Amos

The Jan 30th This Week in Science Podcast covers various topics including:

Today’s interview with Biocomputing expert, Martyn Amos, was a fascinating journey into the future of technology. What we consider computers today won’t be the computers of tomorrow, and computers will likely be integrated into all aspects of life using the miniaturization potential of DNA. While we are still far away from the realization of many aspects of biocomputing, it has come a long way from its humble beginnings.

More Microchip Breakthroughs

Intel, IBM separately reveal transistor breakthrough

In dueling announcements, Intel Corp. and International Business Machines Corp. separately say they have solved a puzzle perplexing the semiconductor industry about how to reduce energy loss in microchip transistors as the technology shrinks to the atomic scale.

Each company said it has devised a way to replace problematic but vital materials in the transistors of computer chips that have begun leaking too much electric current as the circuitry on those chips gets smaller. Technology experts said it’s the most dramatic overhaul of transistor technology for computer chips since the 1960s

The problem is that the silicon dioxide used for more than 40 years as an insulator inside transistors has been shaved so thin that an increasing amount of current is seeping through, wasting electricity and generating unnecessary heat. Intel and IBM said they have discovered a way to replace that material with various metals in parts called the gate, which turns the transistor on and off, and the gate dielectric, an insulating layer, which helps improve transistor performance and retain more energy.

MIT Media Lab Releases Scratch

Scratch is a new programmable toolkit that enables kids to create their own games, animated stories, and interactive art — and share their creations with one another over the Net.

Scratch is designed especially for youth at Computer Clubhouses, an international network of after-school centers in low-income communities. The Scratch project aims to create a programming culture at Computer Clubhouses, empowering youth (ages 10-16) to express themselves fluently and creatively with new technologies.

3 “Moore Generations” of Chips at Once

HP nanotech design could be leap forward for chips by Therese Poletti

The scientists said their advance would equal a leap of three generations of Moore’s Law, a prediction formulated in 1964 by Intel co-founder Gordon Moore that forecast chip makers could double the number of transistors on a chip every couple of years. “This is three generations of Moore’s Law, without having to do all the research and development to shrink the transistors,” said Stan Williams, a senior fellow at HP in Palo Alto. “If in some sense we can leapfrog three generations, that is something like five years of R&D. That is the potential of this breakthrough.”

HP researchers plan to start manufacturing prototypes of their chip design later this year. They also said they expect to see a high rate of defects in the finished products, but that the greater amount of defects will be compensated for by the ability of the circuitry to quickly route around the failed circuits. The model for their chip design is based on a 45-nanometer chip, but with much smaller wiring in the chicken-wire crossbars of 4.5 nanometers.

“Hopefully, by the middle of this year, we will have a real working chip that we have run through an HP fab,” Williams said. “Our goal is that by 2010, we will have something that we can give our customers to play with.”
