Having done most of my web dev work for internal corp sites with IE as the standard, I fell in love with the XMLHttpRequest paradigm a long time ago. Basically you throw up a simple page with some controls and some DIVs. That page stays in the browser during the whole session. As the user interacts with the controls, you submit http requests for backend pages and paste the results into the DIVs, either as HTML or using an XSL transform. Or you use dynamic HTML to doctor individual elements with the results. One neat thing about doing it that way is that session state maintenance goes away. The page that stays in the browser maintains its own state information, just like a standalone client app.
I've been doing this in the IE world for about 5 years, and I thought it was the way Microsoft was going to push web apps in the future. Boy was I surprised when ASP.Net turned it completely around and said now the new cool thing is to make a trip to the server just about every time anything happens. What a waste!
I never heard any good reasons for going it this direction, and I still think dividing the work between the client and server is a good thing. One classic example is a large datagrid populated by a complex query, that allows the user to update individual rows. Rather than the.Net way of sending in the change, requerying and refreshing the whole grid, it's much faster to send in the update as an http request and use dynamic HTML to alter just that one row with the results.
First, the article makes it sound like these charging pads are going to be lying around everywhere (airports, coffee shops...). There have already been articles about businesses viewing "power leeching" as a problem. What's going to change these people's minds?
Second, this gave me a chuckle: A series of recently filed patents may indicate that Slashpower technology is finally ready to march.
Apparently the author lives someplace where filing patents means something tangible!
Magnetic induction charging has been around for a while, as one of the commenters on the article mentions. My SoniCare electric toothbrush recharges that way, although it does have to sit in its charging stand to do it. The SplashPower product seems like a better package, especially the ability to charge multiple devices. The article is short on technical details. I wonder if the obstacle to charging cellphones and other data-carrying devices has been protecting the memory from the magnetic field?

Cooking With Linux
·
· Score: 2, Interesting
The United States is no longer a world leader in art and culture. The most popular word to describe its citizens today is "consumer." Our cities are decaying and dangerous. The implications for the younger generation are terrifying. But with Linux, we could turn all of that around!
Hell-loo?
Fortunately you can benefit from this book even if you don't share the author's view that Linux is the key to the survival of American civilization. I found the 1st ed very helpful in my transition to using Linux as my main system (although I still keep Windows around for reasons other than downloading viruses and worms).
Post early and get modded up! Obviously the poster didn't read the article. The issue is how hard the FBI should have to work to perform a given document search before giving up, and in particular it involves a lawsuit against the FBI for not searching hard enough. The FBI says that in this case they looked as hard as could be reasonably expected, the plaintiff says they didn't. It's a judgement call, and "thoroughness" is hard to quantify.
When they say 160 seconds I wonder if they are talking about Specific Impulse? The definition of specific impulse has never been clear to me, but it has something to do with the amount of thrust you get per amount of fuel burned, and is expressed in seconds. For example, the space shuttle main engines have a specific impulse of about 450 seconds.
I did RTFA, and frankly I want this guy's job. Not only does he get to program a robot to dance, he gets money from people who believe this is a better way to preserve Japanese culture than, say, making videos of people dancing. I bet I could convince these same people to pay me to eat at expensive Japanese restaurants every night and save my shit in a jar.
You can never eliminate the risk of terrorism. All you can do is minimize it. Some believe in locking down everything and everybody and trusting a few people with the keys. Others believe a truly free society produces fewer people inclined to cause trouble. The philosophy Americans live under depends pretty much on who raises the most campaign money.
Poor counterexamples? Seems to me these are perfectly ideal counterexamples. The thing that interests me is that men don't seem to feel inadequate when they see Duke Nukem or the Pittsburg Steelers, yet women do when they see Lara Croft or Charlie's Angels. Why is that?
We caution that this study does not establish a cause-and-effect relationship between restricted sleep and obesity
And yet the whole point of the article seems to be to dangle sleep in front of the readers like another weight loss carrot on a stick.
Many computer geeks lack fashion sense and neglect basic hygiene, but dressing dorky and showering twice a month won't help you write better code. Same principle applies until somebody does a controlled study measuring sleep changes and weight changes.
He also dodges the question of a robot insurrection, a possibility that will not have escaped anyone in the industry after the release of the Will Smith film I, Robot.
I'm not worried about a robot uprising. What scares me is that a robot that can play in the World Cup can also quietly and effectively kill me in a dark alley, take my wallet and return across town to its waiting owner. If pursued by police it could erase its memory or outright destroy itself to protect the owner's identity. I don't recall ever reading a sci-fi story about a human master thief overseeing a gang of robotic pickpockets and burglars, but if they can play football why not?
Here is a fascinating article describing a design for a heavy lift rocket based on the SaturnV form factor, but using a Gas Core Nuclear Reactor engine. Non-polluting and completely reusable, it would lift 1000 tons of cargo into orbit -- enough to take up a space hotel in one go -- and return with an equal amount of cargo to a powered landing. Compare that to the shuttle's 30-ton capacity. Interesting reading, even if you have a nuclear=evil filter. It would be cool to see those beautiful behemoths flying again.
The wireless ISP market, which was supposed to be $5-10/year billion by now, is maybe half a billion. My favorite wireless company WaveRider (WAVC.OB), which went up to $16 during the last dotcom boom, is sitting at $0.19 today. Me =:-(
Yeah, the articles contradict each other. Looks ilke somebody got their numbers mixed up. But any way you look at it, a high ridge running around the equator like that is pretty weird and cool. It will be interesting to hear theories of how it got there. I'm sure the face-on-Mars enthusiasts have it figured out already and are updating their websites at this very moment.
...is why did you quit your well paying job before you even applied to grad school? I would have applied and waited until I got accepted somewhere, then quit. There must be more to this story.
Exactly. Currently more than 1% of American males are in prison -- highest percentage of any nation in the world. Instead of making it legal to do things millions and millions of citizens demonstrate daily that they WANT to do, our lawmakers are doing their best to serve the copyright-holding industry that pays the advertising bills to keep them in office.
Somehow I don't think that's what Lincoln meant by "government of the people, by the people and for the people." But what do I know, I'm just a citizen, oops I meant "consumer."
If the figure of 10,000 is right, then we would only have to cover 1/10000 of the Earth's surface (350 million km2) with 100% efficient collectors to satisfy all our energy needs. That would be 35,000 km2. With 30% efficient collectors it would be more like 100,000 km2. That's a lot of real estate, but only about 1% of the land area of the United States, which is a far cry from "completely covering the Earth with solar cells."
The US uses about 25% of the world's energy, so converting just our economy to solar electricity would take 25,000 km2 of solar collectors. There's plenty of room for that in the deserts and prairies of the country's middle section, and in smaller bits and pieces all over. House rooftops across the southwest immediately come to mind.
Complete conversion to one kind of power is totally unrealistic for many reasons, but certainly there's room to generate a significant amount of our energy from solar, provided the cost is right. In any case, this technology certainly has a lot more potential than using shirts to recharge mp3 players.
From the First review of the IBM-PC For $ 1,565 you get a keyboard and logic unit with 16K RAM and a Basic interpreter in 40K ROM. A cassette interface is built in, I think; but no diskette or monitor at this price -- you use your TV set... A "business configuration" with 64K, dual diskettes, printer, and "color graphics" goes for about $4,500.
Yikes! Hard to imagine people bought those things!
The 2038 article referenced mentions a time error happening on Jan 10, 2004, but offers only a line of C to explain it. Can anybody clarify what is supposed to go wrong 5 days from now?
