The Sunny Side of Asteroids

Asteroids with moons, called binary asteroids, are fairly common in the solar system. But scientists haven't been able to figure out the dynamics of these asteroids, especially how the moons form. But a group of astronomers studying binary asteroids say the surprising answer is sunlight, which can increase or decrease the spin rate of an asteroid. The researchers also say that since there are a number of "double craters" on Earth – side-by side craters that appear to have formed at about the same time — these binary asteroids may have hit our planet in the past. The image above is of twin circular lakes in Quebec, Canada, formed by the impact of an asteroidal pair which slammed into the planet approximately 290 million years ago. Similar double craters also can be found on other planets, as well.

Understanding simple numbers the key to success in small business says online

Understanding simple numbers the key to success in small business says online - Edwards, who is also a chartered accountant, says up to date financial data is critical to manage a business well, particularly in crucial start up or expansion phases. “Most people would say a big increase in sales is a good thing in business, but ironically it can be a disaster because of the effect on cash flow,” he says. “If you’re not on top of your basic numbers, you risk being saddled with a huge debt to your suppliers that you can’t pay because you haven’t received the money from your customers yet. If you’re on top of it you can plan for it.” “Entrepreneurs who know their numbers have a tremendous advantage.

Why ISPs' "Stand" Against Child Porn Is Actually Not a Stand Against Child Porn

TechDirt has an insightful article on the recent push for ISPs to turn off Usenet access under the guise of fighting child pornography. Unfortunately, the "stand against child porn" isn't actually a stand at all, it seems more like ignoring the issue while trying to snag some headlines and good will. "Taking a stand against child porn wouldn't be overly aggressively blocking access to internet destinations that may or may not have porn (and there's no review over the list to make sure that they're actually objectionable). Taking a stand against child porn would be hunting down those responsible for the child porn and making sure that they're dealt with appropriately... Also, this sets an awful precedent in that the ISPs can point out that it's ok for them to block "objectionable" content where they get to define what's objectionable witho

The End of Gamers

Think of all the things you can do with a photograph. You can document the atrocities of war, as photojournalists sometimes do. You can record fleeting moments in time, as did documentarians like Henri Cartier-Bresson and Robert Frank. You can capture the ordinary moments of family life, as many people do at birthday parties or holidays for an album or shoebox archive. You can take a snapshot reminder of a home improvement project in order to buy the right part at the hardware store. An automated street intersection photograph can capture license plate for future ticketing, and a pornographer can capture a nude body for future titillation.

How Does RSS Work? What Can I Do With RSS?

Really Simple Syndication feeds can be extremely useful! The purpose of RSS is to regularly update your hobby interests by receiving dynamic web feeds directly to your screen. Examples include: tracking DVD prices at Amazon, watching for cheap airfares, following the Don Imus controversy. You can get the latest gossip on Anna Nicole Smith's baby, receive the latest wallpaper from your favorite web photographer, or follow the NHL hockey playoffs. You can get the joke of the day or the quote of the week. You can even get barbecue recipes! There are so many interesting things you can do with RSS. Here are some suggestions to get you started:

'Flu Vaccination' Protects Bacteria Against Virus

Bacteria – like people animals and plants – can become infected by a virus. Researchers at Wageningen University, together with colleagues from England and the United States, have unravelled a mechanism with which bacteria can defend themselves for a longer period against threatening viruses. Over the long term, this research offers possibilities to protect bacteria used in industrial processes against viral infections by giving them a 'flu vaccination'.

A Turning Point for Touch Screens, Says the NYT

The New York Times has a story up on the suddenly brisk market for touch screens and the devices which can make use of them, which it says "has grown quietly for years, both in commercial applications and in consumer devices." Besides the obvious (the iPhone, and Apple's use of multi-touch generally), the article also mentions the recent inclusion of Israeli company N-Trig's version of multi-touch technology in a Dell notebook computer, and some of the other places you can expect to see touchscreens instead of display-only ones in the near future — if the price drops quickly enough.

Zumobi Launches Its Widget User Interface For BlackBerry Devices

imageZumobi, which has created an ad-supported user interface using widgets, said its BlackBerry application is now officially available. In addition, the Seattle company said it has new widgets from NPR, AP Olympics report, Major League Baseball, Facebook, Twitter (pictured) and from the blog “BlackBerry Cool”.

Zumobi, which was spun off from Microsoft (NSDQ: MSFT), already has a Windows Mobile app, but has a lot of competition, the largest of w

Evidence of Russian Cyberwarfare Against Georgia

An anonymous reader writes "In what seems to be a repeat of what happened in July, a few news sites have mentioned that there is evidence of a campaign against Georgia. For example, both the government's and the president's sites are inaccessible, among other official websites. For some analysis, the RBN Exploit blog demonstrates various traceroutes that have failed to several sites. They also claim that the RBN (Russian Business Network cyber-crime organisation) are behind the attacks, and that 'Many of Georgia's internet servers were under external control from late Thursday,' before the actual war began. Finally, according to this Twitter account of someone in Georgia (written in Russian), he claims that 'Russia has blocked access to Georgian websites from within Russia' (rough translation).

The limits of iPhoto slideshows

I have iPhoto ’06 and find that I can create a marvelous slideshow, but I can’t do anything with it—cannot post to MobilMe, can’t drag to my iDisk, can’t drag to my Desktop. If I want to share it, it seems the only thing I can do is export my photos to iMovie and create a mini-movie with my still photos, and then save it and hope my PC friends can see it.

Solving the Asteroid " Meteorite Puzzle

Astronomers studying ways to deal with incoming near-Earth asteroids (NEA) that might be on a collision course with our planet want to know in detail what these space rocks are made of. The better they "know the enemy" the better they can come up with ways to destroy or change the course of NEAs. Since we've only studied a couple of asteroids up close with spacecraft, the best way to learn more about the composition of asteroids should be fairly easy: just look at meteorites that fall to Earth, which are small chunks of asteroids. But in doing so, researchers discovered quite a huge discrepancy. The vast majority of asteroids that whiz by Earth are of a type that matches only a tiny fraction of the meteorites that most frequently hit our planet.

Real-World 3G Monthly Cost With Taxes and Fees?

Kristl writes "I have called AT&T and walked into several AT&T stores to ask 'How much will an AT&T phone plan cost per month with taxes and fees and everything?'. No one can answer this question. They are evasive and become testy when I push them on it. Their answer is they can't tell me what the government is going to charge me as the fees can vary month to month, but I've been an AT&T customer for several years, and my taxes and fees have not varied more than a dollar in all of that time. So I question them: 'Can you just tell me what the taxes and fees will be for a 3G plan in California that has the basic calling plan, basic data plan, and the basic text plan?' I even do the math for them, that's $75. Okay AT&T, what are the taxes and fees on $75? Oh, they can't tell me that, as the taxes and fees can vary from month to month.

DVD Shatters Inside Drive! What Next?

I was scared to death when I heard the loud shot-like noise that came from the DVD disk I was playing. Apparently the disk shattered inside the drive! The drive is wide open but it won’t close, and half the disc seems to be inside the drive somewhere. No other CD can go in at all. How do I take out the rest of the CD broken inside? Can someone please tell me how can I open the CD player inside the computer? I need to see inside so I can remove the rest of the disk. How did this thing happen? My computer is working fine. I mean I even turned it off and on again to see what could happen. Nothing. Can someone tell me if I should open the computer CPU case so I can remove the pieces? Thanks, Mary
