Broadband using LED lamps

Broadband through LEDs tips up article tells that German Scientists believe the light coming in to your home could by encoded to receive a wireless broadband signal. The scientists think they can transport data at high bandwidths (currently 230Mbps) by generating a signal in a room by slightly flickering all the lights in unison. The

LED lamp challenges

Nowadays there is ENERGY STAR rating for solid state lamps in USA. Solid-state lighting (SSL) products that meet efficiency and performance criteria set by the U.S. Department of Energy can earn the ENERGY STAR. For more details refer to the ENERGY STAR Requirements for SSL Luminaires. In December 2009, DOE published ENERGY STAR criteria for

About THX certification

THX began life as part of LucasFilm. The initial goals for THX was to ensure that movie audiences in theaters heard the same audio that sound engineers heard in the listening booth after the final audio mix. Eventually, that goal has mutated. The new THX idea was to ensure that home theater buffs heard the

Problems with old Java applications

The main selling points of Java is that it can actually be used on any computer. All that the computer needs is an interpreter for Java bytecode. Such an interpreter simulates the Java virtual machine in the same way that Virtual PC simulates a PC computer. Theoretically if you write a Java program well, it

Acceleration of program execution

Current design methodologies, whether for software or hardware, are in constant pursuit of making applications faster. In the office PC environment there is more than enough power for typical business applications, and they can be written using tools that are not the most optimized for execution speed (for example Java, .NET, scripting languages, web application

PC is not irrelevant

Google says desktop PC is three years from ‘irrelevance’. Google Europe boss John Herlihy told a “baffled” conference audience that very soon the smartphone will completely eclipse the desktop. “In three years time, desktops will be irrelevant,” he said. “In Japan, most research is done today on smart phones, not PCs.” Herlihy was trying to

How low can 32 bits processors go?

Moore’s Law observes that the number of transistors doubles for the same area every two years. Strange that this law has hold for a long time. This has made some people to predict that that 32-bit processors will replace 8-bit processors. The argument starts with the fact that the relative size difference between an 8-
