China cleaning up its spam problem, U.S to follow

Earlier one of the largest source of the world's spam, now China has been gradually fading off the list of the world's top spam-producers. Right now Cisco Systems' IronPort group ranks it at number 18 in terms of spam-producing countries. That's a big drop from two years ago, when it consistently ranked in the top five.
China has more than 420 million Internet users, according to the International Telecommunications Union, and many of them are connecting via hacked computers. Back in 2009, those hacked systems had been pumping out spam at a pretty good clip. In January of that year, China was ranked number three spam-producing country in the world, according to data compiled by security vendor Sophos.
But by the end of 2009, spam from China started to drop off significantly, according to Chet Wisniewski, a Sophos researcher.
Sophos now ranks China as spam producer number 20, right behind Spain.
"This is the first time in recent memory that China has not been in the top 10," said Cisco Research Fellow Patrick Peterson, in an e-mail interview.
According to him, China got serious about the issue in 2006, launching an anti-spam initiative that brought network operators and security companies together to address the problem. Peterson described this initiative as "dramatically successful."
"China has been notable in the amount of spam that's not coming from China now," said Michael O'Reirdan, chairman of the Messaging Anti-Abuse Working Group and a distinguished engineer at Comcast. Spam fighters from the U.S. are now working more closely with members of the Internet Society of China -- the group behind China's anti-spam effort -- to work out standards and better ways of cooperating, O'Reirdan said. They're set to outline these efforts in a report, due next month, entitled "Fighting Spam to Build Trust."
Perhaps the U.S. will learn a thing or two from China. According to Sophos, the U.S. remains the top-spamming country and the source of about one-fifth of the world's spam. Security experts say many of those messages are crafted by spammers residing outside the country, but the fact that they have so many hacked machines in the U.S. at their disposal is a major problem.
Cisco says things have improved in China as ISPs have become better at working with customers to cut down on the spam problem.
According to Wisniewski, China has made it tougher to register new Internet domains and has put on stricter controls over who is allowed to send out e-mail -- both of which may have helped reduce spam. "We don't really have good insight into what exactly is going on in China, because they keep a lot of that under wraps," he said. "It's probably more about censorship than about stopping spam, but the net effect is that it has stopped spam."
There were some arrests for criminal spamming late last year in Russia, and that country is now the focus in the fight against spam, according to Richard Cox, CIO of the anti-spam group Spamhaus. He applauded the joint U.S.-China effort.
"The majority of the criminal spammers have already moved their activities from China to Russia," Cox said. "There is still a lot of work to be done in solving the problems of corruption and lawlessness in Russia that make it the international leader in spam and cybercrime."

Yahoo to close Yahoo! Publisher Network at the end of April

Yahoo has announced that it will close the Yahoo Publisher Network, the company's answer to Google AdSense.
The Yahoo Publisher Network, an advertising platform enabling small Web publishers to place ads on their sites to drive revenue, will officially close on April 30.
In an e-mail sent to Publisher Network users, Yahoo said users of its service might want to consider moving to Chitika, another ad platform that the company says serves more than "2 billion monthly impressions across more than 80,000 Web sites." Chitika has posted a page to help Yahoo Publisher Network users join the service.
Yahoo said the closure of the Publisher Network is a necessary step, as it moves to further focus on its own in-house ads.
"Yahoo continuously evaluates and prioritizes our products and services, in alignment with business goals, and our continued commitment to deliver the best consumer and advertiser experiences," a representative wrote in an e-mailed statement. "After conducting an extensive review of the Yahoo Publisher Network beta program, it was determined that the resources that would be required to advance the program to the level expected by our publishers would be better utilized in other areas of Yahoo's business."
Publisher Network joins a growing number of services that Yahoo has shut down for not making strong financial sense. One of the more notable examples occurred last April, when the company announced that it would be shutting down GeoCities and yahoo is also shutting del.ic.ious-social bookmarking site. GeoCities was officially discontinued in October.

China blocks LinkedIn, ramps up Internet censorship

The blocking of the site is likely tied to China's efforts to stifle mention of "Jasmine Revolution"
The social networking site LinkedIn has been blocked in China, a move that analysts say is tied to Chinese government efforts to suppress mention of a "Jasmine Revolution" on he Internet.
On Friday morning, LinkedIn was inaccessible from Beijing, producing an error message. Linkedin confirmed via email that the site has been blocked for some users in China. "This appears to be part of a broader effort in China going on right now, involving other sites as well," said Hani Durzy, a Linkedin spokesman.
Internet censorship is prevalent in China. Content and websites deemed politically sensitive are routinely taken down or blocked. But in the past several weeks, government censorship has grown more restrictive following mass protests in the Middle East that have toppled governments there. The term "Jasmine Revolution" refers to the pro-democratic movement that began in Tunisia last December and spread to other Middle Eastern countries.
Calls on the Internet for China to stage their own "Jasmine Revolution" began last week.
Chinese government censors, however, were quick to prevent any mention of the term from spreading far. This past weekend, the term "Jasmine Revolution" was blocked in searches on Chinese microblog sites. Users were also barred from posting information using the term on Chinese social networking sites like Renren.com.
Mention of the Jasmine Revolution has also begun appearing on LinkedIn. One user with the screen name "Jasmine Z" expressed their opinion on the potential for revolution in China via posts on the site.
"Whoever was trying to do this thought LinkedIn would be a good way to get into China," said Bill Bishop, an independent analyst who watches the China IT market. But the government was quick to catch on and blocked the site, he added.
The blocking of LinkedIn could follow the path of other U.S.-based sites that have faced troubles with China's Internet censors. In 2009, following ethnic riots in China's western Xinjiang region, both Facebook and Twitter were blocked. The Chinese government also decided to shut down the Internet in the region for several months.
The Chinese government has "been explicit in that they view foreign social networking sites as potential tools for subversion," Bishop said. "It's a surprise LinkedIn wasn't blocked earlier."
In deciding to block both Facebook and Twitter, the Chinese government also made way for China's own social networking sites to fill in the void and become popular. The country now has several Twitter and Facebook clones. The country itself has the world's largest Internet population at 457 million users.

McNealy: Sun could have won out over Linux

Former CEO says 'Google today would be running on Solaris' if Sun had not mishandled its OS
Sun Microsystems' mishandling of Solaris on the Intel platform left an opening for Linux to become established, when the company's Solaris OS could have won out instead, Sun co-founder and former CEO Scott McNealy said when interviewed Thursday evening by former Sun President Ed Zander at a Silicon Valley business and technology forum.
Sun was acquired by Oracle early in 2010 after facing heavy losses amidst a poor economy and industry-wide trends toward Intel and Linux systems, which were not Sun specialties. But things could have worked out differently, according to McNealy.
Sun had its Solaris x86 product, which the company kept reviving and cancelling. "If we had just grabbed the Intel Pentium chip and done a one-way and two-way pizza box with Solaris on it, Linux never would have happened," McNealy said. "Google today would be running on Solaris." Oracle is still offering and developing Solaris.
McNealy and Zander also recalled how close Sun came to acquiring Apple Computer in late 1995 and early 1996. "We were literally hours away from buying Apple for about $5, $6 a share at that time," Zander said. But an investment banker on the Apple side put in so many terms that Sun could not afford to make the deal. "He basically blocked it," McNealy said.
Last night's forum, sponsored by the Churchill Club, was held on the 29th anniversary of the founding of Sun. Once the company went public in 1986, it was technically for sale, McNealy said. Sun fetched $7.4 billion from Oracle. "Twenty-nine years ago, if you had [asked] me, would you take that [offer], yes I probably would have taken it."

Microsoft notes Windows Update "inconsistencies," provides fix


Any time Microsoft pushes an update to a few hundred million users, you can expect some hiccups. With Windows 7 SP1, Microsoft has quietly acknowledged an “inconsistency” that might cause more problems than normal. Here’s the fix.
Any time Microsoft pushes an update to a few hundred million users, you can expect some hiccups. I’ve been monitoring the progress of Service Pack 1 for Windows 7 and Windows Server 2008 R2 since it was released to the public earlier this week, both on Microsoft’s official Windows Update forum and via e-mail and Twitter.
So far, aside from the issue with non-bootable partitions that I highlighted yesterday, this looks like a successful rollout. But it’s not completely trouble-free. Most of the error messages I’m seeing in reports have to do with Windows Update, with error codes like 80073712, 800706BE, and 8024200D. Those sorts of errors have been a fact of life with Windows Update for years, but this time around, Microsoft has quietly acknowledged an “inconsistency” in the Windows Update code that might cause more problems than normal.
In this post, I highlight a handful of tools you can use to fix these Windows Update problems if you run across them.
The quickest and easiest repair option is the Windows Update Troubleshooter. Open Control Panel, click in the search box, and type troubleshoot. Click the Troubleshooting link at the top of the search results, then click System and Security, and finally click Windows Update. The troubleshooter runs quickly. On my system, which had no noticeable issues with recent updates, it detected a minor problem and fixed it.

The entire process took less than 90 seconds and did not require a reboot.
If you’re experiencing Windows Update errors and that troubleshooter doesn’t work, haul out the big guns: the System Update Readiness Tool for Windows 7. According to a Microsoft support document published just a few days ago:
This tool is being offered because an inconsistency was found in the Windows servicing store which may prevent the successful installation of future updates, service packs, and software. This tool checks your computer for such inconsistencies and tries to resolve issues if found.
If you’re unable to apply the Service Pack 1 update to Windows 7, consider downloading and running this utility. Choose the version that applies to your installation:
So far I’ve seen no indication from Microsoft on how widespread these “inconsistencies” are. I’ve asked a Microsoft spokesperson for comment and will update this post with further details.

Scientists investigate the possibility of wormholes between stars

Wormholes are one of the stranger objects that arise in general relativity. Although no experimental evidence for wormholes exists, scientists predict that they would appear to serve as shortcuts between one point of spacetime and another. Scientists usually imagine wormholes connecting regions of empty space, but now a new study suggests that wormholes might exist between distant stars. Instead of being empty tunnels, these wormholes would contain a perfect fluid that flows back and forth between the two stars, possibly giving them a detectable signature.
The scientists, Vladimir Dzhunushaliev at the Eurasian National University in Kazakhstan and coauthors, have posted their investigation of the possibility of wormholes between stars on arXiv.org.
The scientists began investigating the idea of wormholes between stars when they were researching what kinds of astrophysical objects could serve as entrances to wormholes. According to previous models, some of these objects could look similar to stars.
This idea led the scientists to wonder if wormholes might exist in otherwise ordinary stars and neutron stars. From a distance, these stars would look very much like normal stars (and normal neutron stars), but they might have a few differences that could be detectable.
To investigate these differences, the researchers developed a model of an ordinary star with a tunnel at the star’s center, through which matter could move. Two stars that share a wormhole would have a unique connection, since they are associated with the two mouths of the wormhole. Because exotic matter in the wormhole could flow like a fluid between the stars, both stars would likely pulse in an unusual way. This pulsing could lead to the release of various kinds of energy, such as ultrahigh-energy cosmic rays.
For now, the difficult part is calculating exactly what kinds of oscillations are occurring, and what kind of energy is being released. This information would allow scientists to predict what a wormhole-containing star might look like from Earth, and begin searching for these otherwise normal-looking stars.
