    Well, this is awkward. As the IBM PC celebrates its 30th birthday today, one of its original designers is already mulling the end of its reign. In a blog post penned this week, Mark Dean, IBM's CTO for the Middle East and Africa, reflected on the dawn of the desktop era and looked forward to its seemingly inevitable demise. "When I helped design the PC, I didn't think I'd live long enough to witness its decline. But, while PCs will continue to be much-used devices, they're no longer at the leading edge of computing. They're going the way of the vacuum tube, typewriter, vinyl records, CRT and incandescent light bulbs." Dean added that he's glad his company sold its PC business to Lenovo in 2005, as part of a move that, according to him, allowed IBM to position itself at the forefront of the "post-PC" era. No word yet on when the funeral rites will be held, but you can read the full post at the source link, below.

  • Study says LEDs are about as efficient as compact fluorescents, all things considered

    As we've seen with the slight resurgence of new and improved incandescent light bulbs, the amount of energy used to actually light up the bulb isn't necessarily the whole measure of energy efficiency. There's also the small matter of producing the bulb, shipping it around the world, and eventually disposing of it. With that in mind, the Siemens Corporate Technology Centre for Eco Innovations conducted a study that compared regular compact fluorescents to LED lamps -- using one 25,000-hour LED lamp as a constant, compared to 2.5 10,000-hour compact fluorescents (and 25 1,000-hour incandescents). While it's still holding back on some of the finer details, the group did apparently find that LEDs are no more or no less energy efficient than compact fluorescents when the entire lifecycle of the bulb is taken into account, although it is quick to point out that LEDs should eventually win out as they become more efficient to produce.
