This morning the news came over the internet: Dennis Ritchie has died.Dr. Ritchie doesn't have the mainstream adoring following of Steve Jobs, but he can take considerably more credit for the creation, and even the aesthetics, of the computer world we live in. It's almost impossible to find a personal computing product or paradigm that doesn't owe a direct debt to Ritchie.
Typing in Braille is tricky, requiring clunky and expensive dedicated devices--some costing as much as US$6,000--with limited functionality beyond their primary design purpose. But a team of researchers at Stanford University in California, including an undergrad on loan from New Mexico State University, have created a touchscreen interface that brings the ability to write in Braille to tablet PCs.
Researchers on two continents are reporting two big breakthroughs in quantum computing today - a quantum system built on the familiar von Neumann processor-memory architecture, and a working digital quantum simulator built on a quantum-computer platform. Although these developments are still constrained to the lab, they're yet another sign that a quantum leap in computing may be just around the corner.
