UPS rolls with lightweight composite-material truck

To green up its iconic brown delivery trucks, UPS is scrapping aluminum in favor of lightweight composite material.

The company last month began testing five delivery trucks built using a plastic-like material that reduces a truck's weight by about 1,000 pounds, or 10 percent. Although that may seem minor, it allows UPS to use a smaller, 4-cylinder diesel engine and get a projected 40 percent improvement in fuel efficiency.

The cost of the trucks is roughly the same, according to UPS executives. The material meets safety requirements and the strength of composite materials, which are widely used in … Read more

What to install on a tiny Windows laptop

At the end of December, my colleague Seth Rosenblatt put together a thoughtful and in-depth Windows Starter Kit that collects the best-of-breed freeware applications for all categories. But what if your new Windows computer can be balanced on the palm of your hand and contains only a whiff of RAM?

Take, for instance, the tiny Acer AspireOne laptop that my mother purchased on little more than a whim and a phenomenal deal. Not for kitchen lookups of recipes or way to win dinnertime debates, as I had imagined when we first slipped the preemie out of its box, but as … Read more

Logitech keyboard lights up the night

Night owls, boogey monsters, and vampires rejoice: the Logitech Illuminated Keyboard is here to help you work in darkness, away from the harsh light of the sun. The underside of each key houses a tiny microlight that emits a soft blue glow in low-light conditions, effectively letting you work in the dead of night.

Like the Logitech diNovo Edge, the Illuminated Keyboard incorporates Perfect Stroke to help you type faster and more accurately. The system allows for a wide 3.2mm stretch spanning each letter and an even amount of vertical depression across the the flat of the keys, so … Read more

Find a laptop to match your lifestyle

One of the biggest challenges when you're in the market for a new laptop can be translating hard specs into something that's meaningful to your life. Should you buy a 13.3-inch screen or a 15.4-inch screen? Do you want a 2.4GHz processor and 1GB of RAM, or would it be better to have a 2.0GHz processor with 2GB of RAM?

The answer to these questions, of course, is that it depends. It depends on your budget, to be sure, but also on how you want to use your laptop. With that in mind, we'… Read more

AMD's gift to software developers

On Monday, AMD released a proposal for "Lightweight Profiling" instructions (or LWP; download here), describing a new way for software developers to gather information on software while it runs.

I've only had a few minutes to check out the document, but it looks pretty interesting. Existing performance analysis tools, like Intel's VTune and AMD's CodeAnalyst, generally create significant overhead when gathering performance information. They usually need code that runs in supervisor mode, for example, and they're just for developer use--they aren't meant to be used in production systems.

LWP lets applications gather their … Read more
