War Brewing on the Inexpensive Laptop Front 370

The Christian Science Monitor has an interesting look at the war brewing on the inexpensive laptop front. With everything from the Eee PC to the OLPC, the trend in slimming and trimming seems to be continuing. "The market segment is so new it doesn't have a name yet or even an agreed-upon set of specifications. Intel, the chipmaker, calls the category "netbooks," recognizing that much of what people do on their laptops involves going on the Net. The new machines are also being called ultra-low-cost PCs, mininotebooks, or even mobile Internet gadgets. In appearance, they have the familiar clamshell design, but they're smaller, with seven- to 10-inch screens. They offer full keyboards (albeit with smaller keys) and weigh less than three pounds. Perhaps most important, the majority cost less than $500 - some as little as $299. Intel says it expects more than 50 million of these netbooks to be sold by 2011. It's introduced a tiny, low-power processor to run them called Atom, which puts 47 million transistors on a chip about the size of a penny."

Tesla Motors Opens Retail Store 442

Tesla Motors has opened their first retail store front to allow the masses access to their new cars. Of course, this is assuming you can afford the $109,000 price tag. "The company told the Associated Press that it is impressed with demand: it has taken 600 orders for the Roadster and has a waiting list of another 400. CEO Elon Musk owns the first one produced. The fancy showroom near Beverly Hills takes its inspiration from Apple stores, Musk said. [...] The company plans to make a luxury sedan next year called the Whitestar that will come in two versions: an all-electric model that will run entirely on its lithium ion battery pack, and a range-extended vehicle that will also use liquid fuel to extend its range. The Roadster will have a range of 220 miles per charge and the mileage equivalent of 135 miles per gallon."

Google Pulls Open Source CoreAVC Project Over DMCA Complaint 207

rippe77 writes "Google has taken down the open-source project CoreAVC for Linux due to a DMCA complaint. The CoreAVC codec is a commercial high-definition H.264 DirectShow filter for windows provided by CoreCodec Inc.. The CoreAVC for Linux project provided various patches for Linux applications (mplayer, MythTV, xine) to use these DirectShow decoder filters in Linux. The takedown is quite controversial, as the CoreAVC project did not provide any copyrighted material — only the means to use the DirectShow filters in Linux." (The takedown notice is not yet up at Chilling Effects, but Google's page has a link that will take you there when it is.)

Comment Re:Iron Man's Suit Defies Physics -- Mostly (Score 2, Interesting) 279

Hydrogen peroxide powered rocket packs fly for around 30 seconds, because they have a specific impulse of around 125, meaning that one pound of propellant can make 125 pound-seconds of thrust, meaning that it takes about two pounds of propellant for every second you are in the air. Mass ratios are low for anything strapped to a human, so the exponential nature of the rocket equation can be safely ignored.

A pretty hot (both literally and figuratively) bipropellant rocket could manage about twice the specific impulse, and you could carry somewhat heavier tanks, but two minutes of flight on a rocket pack is probably about the upper limit with conventional propellants.

However, an actual jet pack that used atmospheric oxygen could have an Isp ten times higher, allowing theoretical flights of fifteen minutes or so. Here, it really is a matter of technical development, since jet engines have thrust to weight ratios too low to make it practical. There is movement on this technical front, but it will still take a while.

Comment My cell does the same thing (Score 1) 305

I have a Samsung VGA 1000 picture phone. It's very buggy. One of the most annoying bugs is the fact that when you pick up a call, you have to be careful.
The cell phone rings until you pick it up, but sometimes it rings once more. This is especially bad because the ringer speaker and the reciever are in fact the same speaker. So, just before you talk to someone at a quite volume only your ear can hear, it rings at a volume that can be heard from 200 feet away. YAY!

Journal Journal: I'm a man 15

It's time to tell the truth. I am a 55 year-old man. My name is Andy Kaufman, and I live in New York City.

I am sincerely sorry to everyone for all my lies.

Journal Journal: Merry Christmas -- $$$$$exyGal

It's not the new year yet, but it seems like a good time to give thanks.

Long story short, I've had a good year. Great job, short commute, and dating again. I've become focused, but with great flexibility. I'm not sweating the big stuff, or the small stuff. The good stuff is in the middle.

May your holidays be commercial-free,

Journal Journal: Teach me economics: Why are tech jobs going to India? 19

American companies are moving tech jobs overseas to India [more info]. Why? Simple, it's all about money. But how is that so? The article says that Indian programmers make 1/10th that of American programmers. Why do they make so much less?

I'm not an economist, but here's a some possible reasons:

Journal Journal: Can the blind see? 30

Xerithane left me a very interesting comment a few weeks ago. Here's a blurb:

For instance, I suffer from a moderately rare eye condition. I will go blind for 3+ hours if I'm exposed to bright light for more than a few minutes. It's like a goths wet dream. When it first happened I was probably 12 or so, and the whole time I sepnt trying to think what blind people saw suddenly made sense.
