The Achilles' Heel of Your Computer

Device drivers account for most crashes and even introduce security problems; a new testing tool could provide an early warning.

Making Optical Switching More Practical For Telecom
From ACM News

Making Optical Switching More Practical For Telecom

Using all-optical controls could speed the transmission of telecommunications data, but optical switches that can work at high bandwidths need a lot of energy to...

How the Apple Ii Taught Programmers to Economize

Imagine trying to program a virtual machine--a software instance that mimics all the characteristics of a physical computer--on a device with 2 kilobytes of RAM...

From ACM News

Mobile Chips Threaten High-Performance Manufacturers

At the end of 2009, Intel was shipping about 80 percent of all x86 processors--the type of chip that powers, for example, Windows-based personal computers. AMD...

Ranking the Most Powerful Supercomputers
From ACM News

Ranking the Most Powerful Supercomputers

The U.S. still leads in high-performance computing capacity, but China is undergoing explosive growth.

Lining Up 'nanodot' Memory
From ACM TechNews

Lining Up 'nanodot' Memory

North Carolina State University researchers have developed a method for growing magnetic nanoparticles that could lead to much more dense computer memory devices...

Redesigning the Web For Touch Screens
From ACM News

Redesigning the Web For Touch Screens

Last week, in an essay criticizing Adobe's Flash platform, Apple CEO Steve Jobs drew attention to, among other things, its lack of support for touch--something...

A Flexible Color Display
From ACM TechNews

A Flexible Color Display

Hewlett-Packard Labs researchers are testing a flexible, full-color display that saves power by reflecting ambient light instead of using a backlight. 

Speedier Bug Catching
From ACM TechNews

Speedier Bug Catching

Engineers have developed new transistors that can locate hardware bugs in a fraction of the time it takes to perform normal debugging. 

Intel Prototypes Low-Power Circuits
From ACM News

Intel Prototypes Low-Power Circuits

The smaller a silicon transistor becomes, the more electrons it leaks. That can mean unreliable, battery-draining chips. Researchers at Intel have come up with...

Magnetic Solder to Wire 3-D Chips
From ACM News

Magnetic Solder to Wire 3-D Chips

A new type of solder can be melted and shaped in three dimensions under the force of a weak magnetic field. Using a magnet to pull the solder up through narrow...

From ACM News

Faster Optical Switching Through Chemistry

New molecules produced at Georgia Tech could enable engineers to build all-optical data routers, ultimately leading to transmission speeds as high as two terabits...

From ACM News

A Faster Wireless Web

Transfers of large amounts of data across the Internet to wireless devices suffer from a key problem: The Transmission Control Protocol (TCP) used to send and receive...

Wi-Fi at the Speed of Light
From ACM News

Wi-Fi at the Speed of Light

A wireless network that uses reflected infrared light instead of radio waves has transmitted data through the air at a speed of one gigabit per second—six to 14...

A 50-Watt Cellular Network
From ACM News

A 50-Watt Cellular Network

An Indian telecom company is deploying simple cell phone base stations that need as little as 50 watts of solar-provided power. It will soon announce plans to sell...

Searching For Disease Clues in Genetic Diversity
From ACM News

Searching For Disease Clues in Genetic Diversity

Over the last few years, scientists have discovered hundreds of genetic variants linked to disease. But the vast majority of that research has focused on people...

What's Inside the Ipad's Chip?
From ACM News

What's Inside the Ipad's Chip?

Despite widespread speculation, nothing beyond what Steve Jobs announced last week is known about the A4 chip at the heart of the Apple iPad. Jobs described the...
