When you open a document or click a link in OS X, the system launches a program that can read it. While OS X provides options to change the programs associated with documents, there is no option to clear all application associations for a file type.

The resource that OS X uses to associate file types (e.g., TXT and PDF) or protocols (e.g., HTTP or FTP) with applications that can handle them is the launch services database. When an application is launched for the first time, the system scans its file-handling abilities and stores them in this database … Read more

Apple investigating power-efficient OLED for mobile devices

In a recent patent application uncovered by AppleInsider, Apple is investigating the use of power-efficient organic light-emitting diode displays for its mobile devices, a technology that could help improve the battery life of iPhones, iPads, and iPod Touches.

Apple is banking on OLED's light emissive approach, which has lower power constraints than LED's light transmissive technology, currently used in iPhones and iPads.

In short, when OLED displays need to show white, it uses a ton of power to do so. As AppleInsider notes, the darks are darker, the contrast ratio is better, and the power efficiency is outstanding--save … Read more
