IT Jobs in US - down and up
Despite losing 38,000 jobs during the fourth quarter, the U.S. high-tech sector had a net gain of more than 77,000 jobs last year, according to a report released today by a Washington, D.C., advocacy group. “That almost seems difficult to believe, given everything that’s happened,” said Josh James, director of research and industry analysis for TechAmerica, which represents more than 1,500 companies. “The way we’re putting it is, we’ve weathered the storm a little bit better than some other sectors,” he said. Last year was the fourth in a row the tech industry added jobs, but the gains were only in software services, up 86,000 jobs, and engineering and tech services, up 26,600. More than 35,000 jobs were lost in high-tech manufacturing and communications services. Although the industry lost jobs during the fourth quarter, the drop was only 0.6 percent, while employment in the total private sector fell 1.3 percent, or by more than 1.5 million jobs. Even in the dismal fourth quarter, software services added more than 12,000 jobs.

Google reveals “secret” server design
I love this stuff. Note the efficiencies:
- The hard drives (top), the most failure-prone components, are held in with Velcro for easy swaps.
- The power supply (left), also attached with Velcro, probably provides the only case ventilation with its exhaust fan, ensuring that air only flows where they want it to.
- The specially-made power supply only outputs 12V and ground (no 5V rails) to a specially-made motherboard that doesn’t need 5V rails.
- The servers each have a backup 12V battery (right), saving massive amounts of energy wasted by multiple conversions in traditional UPSes (120VAC in, stored as 12VDC, 120VAC out, converted to 12V/5VDC by PSU).
Since air conditioning is extremely power-hungry, efficient separation of hot and cold air is essential. It looks like they move all of the hot air to channels along the outside walls of the shipping container, leaving only the center air-conditioned. That way, cold air doesn’t need to run along the exterior walls in hot weather.
Those Google people are smart.
So maybe instead of getting your company on twitter, paying marketers to mention you are on twitter, and paying people to blog about your company, forget all that and just make awesome stuff that gets people excited about your products….
