Chaos Surprises us all

Chaos theory is generally a misunderstood and misused part of science. Essentially chaos theory tells us that some nonlinear systems* are inherently unpredictable even when we understand how the factors involved interact. The typical example used for this is weather prediction so I will stick with that example. We have a pretty sophisticated understanding of how our atmosphere works, yet short-term weather forecasts based on this understanding are generally pretty bad. This is because although we understand the dynamics (e.g., how temperature and pressure interact) really well, we don’t know the pressure, temperature, and everything else at every location on earth to infinite precision. In a nonlinear system these uncertainties can blow up to huge proportions, rendering any precise prediction** of the weather over Cape Town useless. So that takes care of nonlinear systems. Linear systems, on the other hand, are predictable… or are they?

2007 Infiniti G35 to Get In-Dash Storage

What can’t we do with hard drives?

This week at the 2006 New York International Automobile Show Nissan’s Infiniti division is showing off its upcoming 2007 G35 sedan and coupe models which have some new techno-gear on top of the already updated performance specs and a slightly more curvacious body style, according to Edmunds

Infiniti’s 2007 G35 models will feature a hard drive built into the dash which will provide storage space for music files. The idea expands on current features like MP3 capabilities read from CDs or DVDs and Ipod docks built into some Volkswagen and BMW vehicles. In the 2007 G35’s case it will store music on to the hard drive and the model will also feature a compact flash slot according to some sources.The press release from Nissan last week does not go into detail about the hard drive part of things, which is typical of a car maker, but it does spit out some details about the audio system. According to Nissan’s press release, the G35 will feature “a touch screen navigation system with available real-time traffic and the audiophile-quality Infiniti Studio on Wheels by Bose, combining the industry

ATI’s Single-PCB Dual-GPU Plans

ATI’s upcoming RV560 and RV570 will find its way into single-board, dual-GPU CrossFire configurations. Since the GPU cores have integrated composite engines, the cards are capable of Crossfire support directly on the card.

ATI is recommending to its AIB partners that the new 80nm mainstream and value parts will be joined together on a single PCB with a PLX Technology ExpressLane PEX 8532 PCI Express bridge chip. This bridge chip is currently used on ATI Gemini graphics cards such as the GeCube dual X1600 graphics card. The bridge chip itself is nearly the same size as the GPU but only draws approximately 7.38 watts. Preliminary boards show the PEX 8532 heatsink-less which isn’t surprising considering its low power draw. On Gemini graphics boards the PEX 8532 bridge chip (PDF) takes one PCI Express x16 interface and divides the bandwidth in half. This allocates eight PCI Express lanes to each GPU similar to how some motherboards divide sixteen PCI Express lanes across two slots on Intel, lower end SLI and CrossFire motherboards. As the PEX 8532 is a generic PCI Express switch it can be used for other implementations besides graphics switching also. DailyTech has learned Hightech Information Systems (HIS) has dual RV570 products in the pipeline using the PEX 8352 bridge chip. Although RV570 won’t necessarily offer as much horsepower as a Radeon X1900XT, Gemini variants will be able to dedicate one RV570 GPU to physics processing; essentially one GPU can be used for graphics while the second can be used for physics or graphics. Additionally, up to four DVI outputs can be used per card with the help of twin DMS59 interfaces. ATI’s 80nm RV560 and RV570 are expected to arrive in August and September.

A better wall plug


This is just brilliant: A new plug design, angled out from the wall to make it easier to plug things in or out. It was created by University of Notre Dame student Julia Burke, and won an IDSA award this year:

The PLUG-IN’s upward-angled faceplate allows users to better orient themselves and a cord’s prongs before bending over or reaching behind furniture. This creates a direct sightline from the human eye to the faceplate and minimizes the distance necessary for a person to extend. It also provides additional leverage when removing of a difficult plug.

Technically, Burke invented this for the elderly — who have trouble bending far enough down to shove a 90-degree plug into the wall. But the ergonomics here are so dementedly superior to normal wall sockets that I want a full set of these for my household. Right. Now.
