GPU Computing Gems

General-purpose computing on graphics processing units (GPGPU) is very popular right now, and NVIDIA has the lead in this arena with their Compute Unified Device Architecture (CUDA). While in the future, it looks like people will be moving from CUDA, which is proprietary to NVIDIA, to OpenCL, which should be available from a variety of […]

WISE Last Light

To the right is the final image captured from the Wide-field Infrared Survey Explorer (WISE) telescope. The WISE space-born telescope has a 16 inch diameter and surveys light in the infrared wavelengths. The telescope ran out of the frozen coolant needed to keep it cool it to view the universe in the infrared wavelength. We […]

Hands on with the Nintendo 3DS

Blunty was able to get some hands-on time playing with the Nintendo 3DS. Unfortunately, he was only able to show video of it in 2-D mode. Why? Because Nintendo asked him to, of course. Showing it in 3-D mode would look weird since he is shooting the video with a 2-D camera, and we are […]

The LG Optimus Pad Tablet and LG Optimus 3D Smartphone

At the Mobile World Congress 2011 conference in Barcelona, Spain, LG announced their LG Optimus Pad, and the LG Optimus 3D smartphone. The tablet comes with a 5 Megapixel, 3-D capable camera which will allow you to capture either images or video in 3-D. Unfortunately, the tablet is not 3-D capable, unless you count wearing […]

Wireless Graphics card – KFA2 GTX 460 WDHI review

Wireless Home Digital Interface (WHDI) is a wireless standard that allows uncompressed delivery of high-definition video. This would allow a person to have a personal computer in one room with e WHDI capable graphics card, and allow it to stream a movie to a WHDI enabled HDTV in another room. We have talked about WHDI […]

Reality Touchscreen at University of Groningen

Now this is a cool touchscreen! I could see this being used in an actual class instead of just as a tour stop. This is the curved screen in our reality center of the University of Groningen. We just finished building our own touch detection for it. We used six Optitrack v120 slim camera’s which […]


Birth Year Inflation Infographic

This is a fun way to generate a quick infographic that actually means something. BillShrink has an interactive application that allows you enter your birth year, then generates how much something cost when you were born versus today. You can see what it generated for me above. The numbers look about right, except for the […]

A Picture-perfect Pure-disc Galaxy

NGC 3621 is a spiral galaxy about 22 million light-years away in the constellation of Hydra (The Sea Snake). It is comparatively bright and can be seen well in moderate-sized telescopes. This picture was taken using the Wide Field Imager on the MPG/ESO 2.2-metre telescope at ESO’s La Silla Observatory in Chile. The data were […]


Visualization at Supercomputing Centers

Wes Bethel (Lawrence Berkeley National Laboratory) , Kelly Gaither (TACC), Hank Childs (Lawrence Livermore National Laboratory), and Sean Ahern (Oak Ridge National Laboratory) are among the leaders today in the visualization community. They, along with John van Rosendale, Dale Southard, and Eric Brugger, have published a whitepaper titled: Visualization From the Skinny Guys at Big […]
