Xiph.org 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 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 […]
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 […]
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 […]
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, […]
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 […]
The folks at the Top500 have created this fascinating poster, cataloging the growth of the HPC space over the last several years since they began tracking it. Of course, it’s all based on the Linpack benchmark, which has come under fire recently, but seeing various countries grow and shrink is fascinating. Top500 Supercomputing Sites.
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 […]
