Laughing Gas Is Major Threat To Ozone Layer 306

Hugh Pickens writes "The Christian Science Monitor reports that according to new research, nitrous oxide, the colorless, sweet-smelling gas with a long history as a medical and dental anesthetic is the next big threat to Earth's protective ozone layer. Its role in destroying ozone has long been recognized, as well as its role as a heat-trapping greenhouse gas but the new study puts nitrous oxide's ability to deplete ozone into numbers comparable to those used for other ozone-depleting gases covered by the 1987 Montreal Protocol. The researchers note that the health of the ozone layer has been improving since the adoption of the protocol and that nitrous oxide looms large today as an artificial destroyer of the ozone layer, in part because the emissions of other harmful chemicals have been so sharply reduced."

Spammers Use Holes In Democrats.org Security 129

Attila Dimedici writes "According to Cloudmark, 419 spammers are using the democrats.org website to relay email and bypass spam filters. 'The abuse, which dates back at least to the beginning of this month, helps evade filters that internet service providers employ to block the messages. ... The messages were sent courtesy of this page, which allows anyone with an internet connection to send emails. The PHP script employs no CAPTCHA or other measure to help ensure there is a real human being behind each email that gets funneled through the service. The service allows messages to be sent to 10 addresses at a time and even provides a way for people to import contacts they have stored in their address book.'"

Comment Patent doesn't cover podcasts (Score 2, Interesting) 202

The only independent claim specifies "receiving a subscription request to the channel dedicated to the episodic media from the user; ".

This could be debated, but the way I read this is that the client sends a request to the server to subscribe. Of course podcasts are not subscription based (although the client software usually makes this illusion). Podcasts just check an RSS feed for new episodes. The server never has any clue about "subscriptions".

Of course to fully evaluate this one would need to dig into the specification of the patent to see how it used the terminology, but it's not at all clear to me that traditional podcasting is covered by this patent.

Comment Re:Is 240 "safer" than 120? (Score 1) 711

Yes and no.

What kills you is the energy delivered to your heart. Of course the energy delivered to your heart is P=I^2 R. So yes, in a way, the amps kill you.

Here's what you are neglecting. In the situation where you are talking about mains power, the maximum current limit is VERY high, but the voltage is fixed. The current delivered through your body will therefor be determined by good old Ohm's law (E=IR).

Unfortunately if you double the voltage in this situation you also double the current through your body. So 240 is much more dangerous than 120.

By this logic we can't prove anything -- EVER. I'm not saying it's a completely unreasonable argument, but I prefer to have beliefs justified with evidence.

If some being claiming to be god did things that I couldn't remotely understand I would start to consider the possibility of god's existence to be pretty good. Of course I would also consider the advanced alien options -- but in the end, is a sufficiently advanced alien race really that different than god?

This is why the reasonable option is to justify beliefs with evidence, and never hold anything to be 100% true. My beliefs change whenever I receive new evidence.

That's a bit hard to say. But here's a way of thinking about it:

The Shannon-Hartley theorem states that the channel capacity (e.g. the data bandwidth, measured in bits per second) is related to the channel bandwidth (measured in hertz). If we assume a very pessimistic signal to noise ratio of 1:1, the SH theorem says that the cable's bandwidth in hertz will be the same as the cable's bandwidth in bps.

So if we want a cable capable of transmitting information at 1tbps, the cable will need a bandwidth of roughly 1000 GHz. That means that it would be impossible to carry that amount of information using even microwaves. We're talking about at minimum infrared light. Or in other words -- we're talking about fiber optics, not cat5.

Is this a serious answer, though? The vast majority of the land area of the US is almost unpopulated. But *MANY* people live in highly populated areas.

For instance:
San Francisco: 6688 people per square km
New York: 10482 people per square km
Chicago: 4816 people per square km

For comparison, Tokyo has a population density of 5847 people per square km.

So, to re-ask the grandparents question: Why are our urban areas so far behind Japan and South Korea's urban areas?

Submission + - Remote Television Options

empiricistrob writes: In a few months my wife and I are moving to Switzerland to work on the LHC. We're hoping to take US television over with us to help minimize the culture shock. Several off the shelf solutions exist to watch TV remotely, such as Slingbox, but none of them seem adequate. Specifically Slingbox works in conjunction with your DVR, but it seems silly to have two boxes when one properly set up computer should be able to do the task. Does anyone have any recommendations on how to pipe domestic television abroad? I'm currently thinking of setting up something with MythTV. Perhaps use the web interface to schedule recordings and have a cronjob to scp the video over. Are there any better solutions?

Yes, the SDK has serious restrictions. But how can you compare this to microsoft? The whole point with regulating microsoft was the fact that microsoft has a monopoloy. I don't think anyone is going to argue that Apple has a monopoly in the mobile phone market. That's rediculous. If you don't like the iPhone or the iPhone SDK -- go elsewhere. There is plenty of competition. I personally will accept these drawbacks and keep using my iphone.

Submission + - Steve Jobs highest paid CEO - $646 Mil

Whiney Mac Fanboy writes: "Fans of Apple CEO Steve Jobs are quick to point out that he is only paid a $1 salary for his role at Apple. However, according to Forbes he's the highest paid executive in the US — to the tune of 646 Million dollars for 2006. From the article

Forbes said the highest-paid CEOs were not always those that delivered the most to shareholders.Forbes said by its analysis, Apple's Jobs was 36th. Topping the list was John Bucksbaum of General Growth Properties, a real-estate investment trust. Over the past six years, Bucksbaum was paid $US723,000 a year while delivering a 39 per cent annual return to shareholders.
I wonder how much of that $646 Million was from improperly backdated options?"

Comment Re:GCJ, Kaffee, GNU Classpath (Score 1) 535

GCJ will survive because it provides a facility that doesn't exist in the standard JDK (i.e., ahead-of-time compilation).


Well, that would be a reason. But on the other hand, the main developer of GCJ is RedHat, and they may well not feel like continuing it now.

Kaffe will survive because it's BSD licensed.


Kaffe is GPL.

Classpath will initially try to survive by copying large amounts of original Java code into itself, but I suspect will eventually become irrelevant as patches for classpath-using applications become available to allow them to use the original Java class library.


Well, then you know more than I do. And I'm a Classpath dev. :) There are no Classpath-using applications that don't run on the original class library. Classpath is not Mono - we've never accepted any incompatibility against Sun's java, and certainly haven't promoted working around our bugs.

Anyway, there's a good six months or so before we'll be seeing the classlib code from Sun. Yes, if we do continue development (or those who do) will probably be incorporating parts of it, but not large swaths of it. There are some fundamental differences in how the two libraries have chosen to solve certain things, and it's hardly a matter of cutting and pasting some code.

There's also a likelyhood that parts of Classpath are going to end up in Sun's libaries. There are actually things that Classpath does do better. There are also parts of the classlib that aren't going to be open-sourced because Sun doesn't have ownership. Classpath may provide the replacements for those parts.

But all in all, it's a big win for Classpath, regardless. We're getting what we wanted, under the license we wanted it. And we even got Sun to talk to us and ask advice before it all happened. (And judging from the details of their actions, I'd say I they listened well)

In your analogy, it would be Sony causing the backlog, not the people in line. You have a producers and consumers problem and the consumers are actual consumers. It seems fairly trivial to figure out who the producers would be.

Are you arguing, then, that Sony should release the PS3 because people are waiting for it?

What Does the Microsoft ODF Converter Mean? 177

Andy Updegrove writes "It's been a week now since Microsoft announced its ODF/Office open source converter project - time enough for 183 on-line stories to be written, as well as hundreds of blog entries (one expects) and untold numbers of appended comments. Lest all that virtual ink fade silently into obscurity, it seems like a good time to look back and try to figure out what it all means. In this entry, I report on a long chat with Microsoft's Director of Standards Affairs Jason Matusow, and match up his responses with the official messaging in the converter press release. The result is a picture of a continuing, if slow and jerky, evolution within Microsoft as those that recognize market demands for more openness debate those that want to follow the old way. This internal divide means that the proponents of change need to point to real market threats in order to justify incremental changes. This adaptation by reaction process leaves Microsoft still lagging the market, but has allowed those that favor a more open approach to gradually turn the battle ship a few degrees at a time."
