next generation video: Introducing Daala

by Randall Handon June 21, 2013 is now leaking out a few details about their new video coded “Daala” that trades the classic DCT representation of frames and video, used in  most other codecs, for a “lapped transform”. Daala is a new general-purpose video codec currently under development at Xiph.Org. Our performance target is roughly a generation beyond current ‘next-generation’ […]

Nvidia adds ARM platform support to CUDA GPU programming

by Randall Handon June 20, 2013
NVidia has just released their first previews of CUDA5.5 with their usual collection of new bells and whistles, but one big one shows up in this version: Native ARM support for the classis CUDA toolchain. Nvidia says combining high-performance CUDA-enabled GPU accelerators with low-power ARM-based systems on a chip (SoCs) will enable ARM-based systems to […]

The Augmented Lecture Feedback System

by Randall Handon June 20, 2013
Another interesting use-case for wearable AR systems like Google Glass comes from a Spanish university that has integrated it into a lecturer system for monitoring classroom participation. Researchers at la Universidad Carlos III de Madrid have developed the Augmented Lecture Feedback System (ALFs), a HUD glasses interface that teachers can wear while giving a lecture. From […]

LiveMap: The Augmented Reality Motorcycle Helmet of the Future?

by Randall Handon June 20, 2013
Over in Russia, a new entry into the ever-growing augmented reality space comes in the form of a special Motorcycle helmet. Designed in Russia, the unique helmet design features a head-mounted display with a full-color, translucent picture projected directly onto the visor. An on-board light sensor adjusts the image brightness and translucency based on the […]

by Randall Handon June 18, 2013
A clever, and slightly scary, writeup from Kieran Healy puts a revolutionary-spin on the current NSA PRISM debacle, showing how even all this “useless metadata” can be collected into scary and telling pieces of information.  Specifically, how the membership rosters of 7 social clubs could be used to find the central traitor in the midst, […]

AMD FirePro W5000 vs Nvidia Q2000 in Solidworks 2013

by Randall Handon June 18, 2013
Sapphire Technologies ran an interesting benchmark using SolidWorks 2013 on both the Nvidia Quadro Q2000 and the AMD FirePro W5000, and found the FirePro far superior. Quick Summary: the AMD FirePro W5000 took 1min and 38 seconds. The Nvidia Q2000 took about 3 mins, almost 1.8X times compared to the FirePro W5000. It’s impressive how […]


Top500 Supercomputing Sites Poster

Visualizing Time with the Infinity Hour Chart

by Randall Handon June 13, 2013
Doug McCune has an interesting way of representing 24-hour cyclical data over an infinity symbol (the lemniscate). You follow the time by working your way around the infinity. If you start at the top of the symbol at noon, you would start moving around clockwise to 1pm, then 2pm, etc. You’ll reach the center at […]
