Japanese Cosplayers Keep Fantasies Fresh (With Febreze)

TOKYO — The raging popularity of Street Fighter IV in Japan meant plenty of Chun-Lis and Kens in “cosplay alley” at this year’s Tokyo Game Show.

Many people dressed up as the characters, which are mainstays of Capcom’s fighting-game franchise, while hundreds of others donned costumes inspired by videogames and anime series, both mainstream and obscure.

Cosplay — short for “costume play” — is a popular pastime for anime and gamer geeks in Japan, who express their fandom by dressing in character. Some spend hundreds, even thousands, of dollars perfecting their outfits, but the more serious cosplayers custom-make their own costumes using fabric, a sewing machine and glue. Here are some of our favorites.

Unlike their U.S. counterparts, Japanese cosplayers often hide their true identities, providing fans with “cosplay” business cards and alternate cellphone numbers.

In Tokyo Game Show’s cosplay alley, strict signs forbid onlookers from asking the costumed individuals questions that will invade their privacy.

Cosplayers are great at staying in character for the photo shoots, but when you try to talk to them afterward, they revert back to being polite, courteous humans.

Cosplayers can’t ever show that they are tired. If they did, fans might do what they would do if an in-game fave grew weary — trade them in for a fresh new character.

Cosplayers often carry around a small bottle of Febreze in order to stay fresh throughout the day.

Google fixes problem with Apps Start page

Google has solved a problem that affected the layout and functionality of the "Start" pages of its Apps hosted collaboration and communications suite.

Although the bug had the potential to affect many customers, it manifested itself only in instances when Apps administrators had customized their organizations' Start page, said Rishi Chandra, Google Apps product manager.

The problem arose apparently Thursday afternoon U.S. Eastern Time and was finally solved at around noon on Friday.

Apps administrators who reported problems in the official Apps discussion forum described what they perceived as being an erratic Start page update designed to make it look and act more like iGoogle, the company's personalized home page service for consumers.

However, Chandra said that wasn't the case, although he understands why the administrators would interpret the incident that way, since the iGoogle logo replaced company logos in affected pages. The problem was caused by a system bug that altered Start pages layouts, broke some links and interfered with some "gadget" applications, like the one for Gmail, he said.

With a permanent fix now in place, all affected Start pages should have reverted back to their normal layout and operation without any loss of data or functionality, Chandra said. Google had prematurely declared the problem solved at around 8 p.m. on Thursday, but problem reports kept flowing in.

Google Apps is a hosted collaboration and communication suite aimed at workplace use, and its Start pages are designed as a portal main point of entry for end-users to their applications, such as Calendar and Gmail. Apps' Standard and Education versions are free, while its more sophisticated Premier edition costs $50 per user per year.

The problem was disruptive at New Hope Fellowship in Springdale, Arkansas, which uses the Apps Education edition. The church's Start page was hit intermittently by the bug between Thursday at around 2 p.m. and noon Friday.

"Our users were trained to access their mail through the Start page. Once that didn't work, they could not access e-mail, which is critical to our work. We had to send paper memos around on how to access the mail without going through the Start page. Very frustrating," said Josh Jenkins, New Hope Fellowship's media director and Apps administrator.

This wasn't the only problem New Hope Fellowship's 40 Google Apps users encountered this week. They also lost access to their e-mail due to an unrelated and prolonged Gmail outage that hit some Apps customers this week.

"Google must improve communication with business customers if they wish to be competitive in the corporate IT space. The 2-sentence 'we're working on it' blurbs posted in the [online discussion] groups are an unacceptable way to treat business clients," Jenkins said.

Susan Novotny, Apps Standard edition administrator at a national nonprofit with 30 users in Ontario, Canada, said that the occasional bugs that hit Google Apps "do shake my confidence a little."

"I guess I expect a spectacularly wealthy company to be as reliable as the average e-mail provider," she added. "But they're providing tools no other provider can."

Nelson & Co. Engineering in Birmingham, Alabama, also experienced the Start page bug, but it wasn't too disruptive for its four Apps Premier users, said Apps administrator Ryan Nelson. The company feels that, despite the hiccups, Apps provides it with a great value at $50 per user per year.

"As a Premier user I would think that these issues would not happen. In the long run, Google Apps has been the best technology move we've ever made. Little issues crop up a couple times a year for less than 24 hours: not ideal, but better than anything else we've ever used," Nelson said.

Others were more frazzled, like an Apps administrator identified as Jay in the official discussion forum, who wrote Friday morning: "I now have over 1,200 users that have no idea how to get into their e-mail. The phones are ringing off the hook. What is going on with customer service these days. This really stinks."

The problem wasn't related to a major iGoogle upgrade the company rolled out on Thursday, Chandra said.

The unrelated Gmail problem this week kept users from accessing their e-mail in some cases for more than 24 hours between Wednesday and Thursday. Google declared that problem solved late on Thursday.

During Google's third-quarter earnings conference call on Thursday, cofounder and Technology President Sergey Brin said that there are now more than 1 million businesses using Google Apps.

Google Apps is one of the best-known examples of a new wave of Web-hosted communication and collaboration suites that are emerging as options to Microsoft's Office and Outlook/Exchange suite.

Apps is hosted by Google in its data centers and accessed by end-users via a Web browser. The appeal of Web-hosted software like Apps is that it doesn't have to be installed by customers on their own hardware, reducing maintenance costs and complexity. Apps and others like it are also designed from the ground up for workgroup collaboration.

However, when something breaks on the vendors' datacenters, IT administrators have little or no control over how or when to remedy the problem, and are left to appease their angry end-users as best they can.

In August, Gmail had three significant outages that affected not only individual consumers of the free Webmail service but also paying Apps Premier customers. As a result, Google decided to extend a credit to all Apps Premier customers and said it would do better at notifying users of problems.

Top 10: Google miffs admins, IT jobs, Apple notebooks

Google annoyed administrators when it made changes to Google Apps "Start" portal pages without letting them know it was updating layout and functionality of those pages. Some administrators reported at a discussion forum that they were swamped with angry calls from end-users who couldn't access Gmail accounts. On a slightly brighter note, there are some IT jobs that persevere even in the face of financial difficulty, and Apple unveiled new notebooks to much fanfare. Meanwhile, Mozilla continues work on its mobile browser, code-named Fennec, which was released in alpha this week for use on Nokia Internet tablets.

1. Recession-proof IT jobs: Believe it or not, some IT jobs are still in high demand even in this slumping economy. Unlike some other industries that have been hit hard, IT is seen as a core area that nearly every company needs. As such, there are still plenty of IT skills that can lead to new jobs — or just keep you secure in the job you have now.

[ Video: Catch up on the week in tech news with the World Tech Update ]

2. Apple's new notebooks answer the call for innovation: As expected, Apple showed off updates to its laptop lines this week, with a new MacBook and MacBook Pro. InfoWorld's Tom Yager got a good look at them and came away with a positive impression of the updates in both technology and pricing.

3. Google Apps portal pages malfunctioning: Google Apps "Start" portal pages have become malfunction junctions for some administrators, who complained over two days this week at discussion forums that changes Google made to those pages are making their working lives miserable. The company apparently updated layout and functionality of those pages without telling admins what they were about to do, leading end-users to flood administrators with complaints and issues, including not being able to access Gmail.

4. E-voting report: Several states still vulnerable: E-voting systems will fail on Election Day, Nov. 4, somewhere in the United States, with multiple states that use such systems ill-prepared for the upcoming election, according to a report from three voting-rights advocacy groups. While the report noted that there have been improvements in e-voting systems and election preparations since the last presidential race in 2004, it also found that some states still have not taken even the most basic precautions against technical problems and fraud.

5. Mozilla offers alpha version of mobile browser for N810: An alpha version of Mozilla's mobile browser, code-named Fennec, was released for Nokia's Internet tablets, marking the first public release of the software. Mozilla hopes the release will bring in feedback leading to the next step in its browser road map, which is "optimizing for performance," according to Jay Sullivan, Mozilla's vice president for mobile.

6. Microsoft: "No interest" in pursuing Yahoo deal: Microsoft CEO Steve Ballmer stirred things up — as he is prone to do — when he reportedly said at a Gartner conference that it still makes economic sense for shareholders of both companies for Microsoft to buy Yahoo. His company responded by issuing a statement saying it has "no interest in acquiring Yahoo." Investors responded by giving Yahoo's share price a boost.

7. FBI says Dark Market sting netted 56 arrests: The U.S. Federal Bureau of Investigation, working with other law enforcement agencies in the U.K., Turkey, and Germany, infiltrated online "carder" forums hosted at the now shut-down DarkMarket.ws site and seized compromised accounts and prevented about $70 million in fraud. The two-year undercover investigation also led to the arrests of 56 alleged online fraudsters.

8. Microsoft mulling "instant on" feature for Windows: Microsoft confirmed it is thinking about adding into its Windows client OS a function that would let users have limited access to the OS so that they could turn on their PCs quickly. The company surveyed users about that function and screenshots of the survey wound up on the Engadget blog. Microsoft won't yet offer specific comments about "instant on," but a good guess is that it is contemplating that addition for Windows 7, which is expected out late next year or early in 2010.

9. With eyes on Atom, AMD to detail netbook strategy next month: Advanced Micro Devices will provide its product road map for netbooks at an analyst meeting scheduled for Nov. 13. Netbooks are small, inexpensive laptops that have taken the market by storm, fueled by Intel's low-cost Atom processor. AMD hasn't been competitive with Intel in that area yet, but promises it soon will be.

10. Cybersecurity threats grow in sophistication, subtlety, and power: Malware, botnets, cyberwarfare, threats to VoIP and mobile devices, along with an "evolving cybercrime economy" mean that online threats are becoming increasingly sophisticated, the Georgia Tech Information Security Center said in an annual threat report. Criminals have figured out ways to make such online threats more subtle, and they continue to gain in ability to exploit changes on the Web, including increased use of social-network sites, the GTISC found.

E-voting report: Several states still vulnerable

Several U.S. states still are not doing all they can to ensure the accuracy of votes over electronic voting machines, and 10 states received inadequate grades in three of four categories of safeguards, a report from three voting security advocacy groups said.

Somewhere in the United States, voting systems will fail on Election Day Nov. 4, predicted the report, released Thursday by Common Cause, Verified Voting and the Brennan Center for Justice at the New York University School of Law.

[ For more on how technology is reshaping the race for the U.S. presidency, see InfoWorld's special report. ]

On Election Day, "voting systems will fail somewhere in the United States in one or more jurisdictions in the country," the report said. "Unfortunately, we don't know where. For this reason, it is imperative that every state prepare for system failures."

State protections against voting fraud and e-voting machine failure have improved greatly since the last U.S. presidential election, in 2004, said Pamela Smith, president of Verified Voting. But several states still refuse to take basic precautions to protect the integrity of voting systems, she said.

"There are some folks who still don't get it," Smith said.

The report details which states have not taken precautions against fraud or technical errors associated with e-voting machines and other voting systems:

– Ten states — Colorado, Delaware, Kentucky, Louisiana, New Jersey, South Carolina, Tennessee, Texas, Utah, Virginia — received failing grades in three of four voting security areas.

– Of the 24 states using direct recording electronic (DRE) machines, only three — California, Indiana, and Ohio — get satisfactory grades in all four categories, the report said. Colorado, Delaware, Louisiana, Nevada, Texas, Utah, Virginia, and West Virginia have no state-mandated requirement for emergency paper ballots to be available in precincts that use voting machines, in the case of voting machine failure.

– Nine states — Alabama, Illinois, Kentucky, Maine, New Jersey, South Carolina, Texas, Utah, and Virginia — have requirements for ballot accounting that "fall far short" of the groups' recommended best practices.

– Eighteen states, including Florida, New York, Texas, and Virginia, do not have adequate requirements in place for paper-record backups to e-voting or other nonpaper voting methods. Voter-verified paper records allow states to conduct recounts of voting machine totals, supporters say.

– Another 27 states, including New York, Michigan, Virginia, and Georgia, do not have adequate provisions in place for conducting post-election audits of voting results, the report said.

Others took issue with the report, saying states will be ready for Election Day.

"We are prepared and we continue to make preparations for the general election," said Chris Whitmire, a spokesman for the State Election Commission in South Carolina, a state that flunked three of the four voting security categories in Thursday's report. "We will be adequately prepared."

The report comes too late for changes to be made this year, added David Beirne, executive director of the Election Technology Council, a trade group representing e-voting machine vendors.

"With less than three weeks to go, the election has already begun and now is not the time for new procedures to be adopted," Beirne said. "It is also unlikely that the Department of Justice would grant approval for such changes this close to the election. While well intentioned, the report and recommendations may only drive fear for the voting public, which is not productive at this stage in the process."

The report also fails to recognize steps taken by county election officials to ensure against fraud or errors, Beirne said. "The call for procedural safeguards has been recognized by the elections community in recent years and there is little question that the state and local election officials will be prepared for Nov. 4," he added.

The report points out several shortcomings, but most states are headed in the right direction, Smith said. "Over the next couple of years, I see significant improvement," she said.

In 2004, only eight states had requirements in place for election systems to have paper backups, and a few more used paper backups during the election, Smith said.

This year, 32 states have either voter-verifiable paper ballots, or voter-verifiable paper record printers connected to voting machines statewide, the report said. Four states — Maryland, New Jersey, New York, and Tennessee — have laws that take effect in 2009 or 2010 requiring voter-verified paper records.

Arkansas, Colorado, and Mississippi have paper in most counties. The District of Columbia and Florida have paper ballot systems in all counties, along with paperless DREs, and Florida will eliminate paperless systems altogether by 2012, the report said.

Mozilla offers alpha version of mobile browser for N810

Mozilla plans to release on Thursday an alpha version of its mobile browser for Nokia's Internet tablets.

It's the first public release of the browser, code-named Fennec, and it will work on Nokia's N810 and N800 devices.

[ Track the latest trends in open source with InfoWorld's Open Sources blog. ]

In addition to the alpha release for the Internet tablets, Mozilla is offering a PC emulator that developers can download to their desktops to see some of the features included in the browser and to get a feel for the user interface, said Jay Sullivan, vice president of mobile for Mozilla.

"This is really for our community to be able to test and localize and build add-ons," he said, referring to both the emulator and the Internet tablet release.

Despite being made by Nokia, the Linux-based N800 devices aren't quite mobile phones. They are larger than a phone but smaller than a laptop and can connect to the Internet via Wi-Fi. They don't include cellular capabilities, although users can connect a phone to the device to reach the mobile Internet. The devices are popular with developers because they use open source software, but Nokia has not revealed sales figures to indicate how many are in the market.

Mozilla hopes that this release will result in some good user feedback, Sullivan said. "The next step in the road map is to start optimizing for performance," he said.

His group has simultaneously been developing a version of Fennec for Windows Mobile phones. While Sullivan said they've been working hard on it, he wouldn't reveal a release time frame for that browser. His group has also been looking at developing the browser for LiMo phones that are based on the mobile Linux operating system and for Symbian phones, he said.

Mozilla released a video in June that offered a first look at Fennec. One unique feature to the browser is that it displays control buttons, such as back and forward, off screen. Users flick the screen to the left or right to display and click the buttons. "One of our big goals is to take advantage of the whole screen, because they are pretty small," Sullivan said. The design lets a Web page fill the whole screen.

He also thinks that Fennec will be unique because Firefox developers will be able to build add-ons for it. "We don't claim to have all the answers. We want to build a great product but make it extensible so anyone can hack on it," he said.

Mobile browsing has historically been a painful experience, and countless handset and software makers have created mobile browsers hoping to make them easier to use. While mobile browser development from the likes of AppleGoogle, and Microsoft is unlikely to cease because of Fennec, other mobile browser efforts may, Sullivan said. "When our browser is ready, a lot of folks will stop building custom browsers," he said. "Carriers and OEMs are telling me they'd rather ship Firefox rather than hack together their own browser."

While he wouldn't reveal names, Sullivan said that Mozilla is talking to handset makers and operators about preloading Fennec onto phones. Traditionally, only a very small percentage of phone users load applications onto their phones, so preloading the browser could significantly help distribution.

This isn't the first time that Mozilla has begun work on a mobile browser, and most of its previous attempts have fizzled. For several years, it worked on a mobile browser it called Minimo that included a release for Windows Mobile devices. But last year Mozilla said it wouldn't continue work on that browser, instead focusing on Fennec, which is based on the latest Mozilla platform that also supports Firefox.

Mozilla also developed and later retired a project called Joey that let people save portions of Web sites while on their PC and call up those images from their mobile phones.

While Mozilla has been working on those projects, Apple released its iPhone and included a mobile version of its Safari browser. That browser has been widely praised as a significant improvement over historical mobile browsers because it displays Web pages just as they look on a computer but allows users to easily scroll around and examine the page. Next week the first phone running Google's Android software will hit the market, and it includes a browser developed by Google and based on Webkit, the same technology that fuels Safari. That browser offers a similar improved experience but one-ups Apple's Safari because it can display Flash Web sites.

Mozilla expects to make the alpha download for the Nokia tablets available on Thursday from its Mozilla.org Web site.

Oct. 17, 1973: Angry Arabs Turn Off the Oil Spigot

1973: The Arab oil-producing states impose an embargo against nations supporting Israel in the Fourth Arab-Israeli War, also known as the October War or Yom Kippur War.

The effect upon petroleum-consuming countries was immediate, profound and long-lasting. The oil embargo, and the cut in production that accompanied it, doubled the price of crude and reduced overall supply. That forced gas prices to skyrocket at the pump and led to rationing and the imposition of price controls in the United States and Western Europe. Long gas station lines and frustrated motorists became iconic images of the early 1970s.

It also awakened the West to just how dependent it was on Middle Eastern oil, and how fragile that lifeline really was.

The decision to use oil as a weapon was made prior to the opening of hostilities. Egypt’s Anwar Sadat and Saudi Arabia’s King Faisal met a month and a half before Egypt and Syria attacked Israel. They agreed to play their trump card — in many ways, their only card — when the expected support for Israel materialized, which it quickly did.

The Yom Kippur War, which began with a surprise attack Oct. 6 (timed to coincide with the Jewish Day of Atonement), went badly for the Arabs. After initial gains, the Syrians were driven from the Golan Heights, and an entire Egyptian army was cut off in the Sinai Peninsula. The offensive fell apart, the United Nations and United States brokered separate ceasefires, and it was all over by Oct. 26.

But the embargo continued. Because of the embargo, Arab oil producers were able to wrest control of their vital commodity from the Western oil companies that had been exploiting them for years. When some members of the Organization of Arab Petroleum Exporting Countries, notably the Saudis, followed up the embargo by nationalizing their oil companies, the westward flow of petrodollars reversed itself and the drunk-on-money Middle East cartel that we know today began to emerge.

In the West, and especially in the United States, the embargo and the “oil shock” that accompanied it brought about profound changes. In November, President Nixon signed the Emergency Petroleum Allocation Act, which — among other things — instituted rationing and price controls. A few months later, the United States embarked on Project Independence, an early and failed attempt to make the country energy independent.

As a result, offshore oil drilling became a priority in a way it never had been before.

Later, when the embargo ended and the flow of oil resumed, these correctives were either cut back or abandoned. But the psychological damage was complete: Oil-gluttonous Americans have remained paranoid about their supply ever since.

Finally, on March 17, 1974, Arab oil ministers (with the exception of Libya) lifted their embargo against the United States. But the playing field was forever changed.

Lawsuit Claims Mapmaking Firm Owns Your Neighborhood

A mathematician who pioneered a fractal-based urban-mapping technique is embroiled in a copyright battle that raises legal questions about whether a company can claim ownership of the definition of neighborhoods: their specific locations and boundaries. The dispute highlights a growing movement to quantify the amorphous tendrils connecting communities.

Bernt Wahl had the idea in 2004 to use a blend of mathematical modeling and old-fashioned shoe leather to map out unofficial neighborhoods — areas like Bernal Heights in San Francisco, or New Orleans’ French Quarter — whose borders are drawn mostly in the minds of the inhabitants.

Since then, he’s produced maps defining more than 18,000 neighborhoods in 350 U.S. and international cities, which are used in everything from search localization to epidemiology. The Federal Deposit Insurance Corp. is currently using Wahl’s maps to better understand which neighborhoods are being slammed hardest by the mortgage crisis.

Vermont-based mapping company Maponics is now suing Wahl to keep him from creating any more neighborhood maps “derived from or containing parts of” the original maps he produced four years ago, which defined 7,000 neighborhoods in 100 cities. Wahl did that work as a contractor for a real estate web portal, which then sold the copyright to Maponics. Because American’s biggest metropolitan areas were included in the original batch of maps, the lawsuit could effectively bar Wahl from the mapmaking business for good.

The lawsuit highlights the growing importance of neighborhood data in web applications and science. Since Wahl pioneered the industry four years ago, other companies have entered the neighborhood-mapping field, which has swollen into a big part of a $17 billion localized-mapping industry, says Ian White, CEO of San Francisco-based Urban Mapping.

Neighborhood mapping is being used for marketing, siting new retail outlets, social networking, and analyzing crime patterns and earthquake damage. Yahoo announced in June that it had licensed neighborhood-mapping data from Urban Mapping for 2,000 U.S. cities. Earlier this year, Zillow opened its database of 7,000 neighborhoods to the world under a Creative Commons license.

“Everyone made out like a bandit except me,” Wahl says.

Wahl began his work when he was contracted by real estate portal HomeGain to optimize the firm’s search engine. At that time, real estate site maps were organized either by ZIP code or by census tract, which are both fairly arbitrary shapes drawn with disregard for the differences in the neighborhoods within. The Thomas Guides have long noted neighborhoods, but did not attempt to define where they begin and end.

Wahl saw that as a fatal flaw. “Neighborhoods are really important,” he says. “For example, there’s a census tract that combines downtown Berkeley and North Berkeley. In Berkeley hills, the average age is 57, and downtown it’s 24. The incomes and values are completely different. It made me start thinking that we needed a different way to let people look for homes.”

Working with 15 student interns, Wahl began phoning local-government planning departments, chambers of commerce and other community sources in hundreds of cities. “There’s usually a librarian in each place who remembers the neighborhoods — the trick is finding them,” Wahl says. “And you have to be careful about what people tell you, because they can tend to bleed their home into a better neighborhood.”

Using the anecdotal data, Wahl drew polygons that contain the neighborhoods, then tacked them to base maps created by the U.S. Census. The new maps hit big. HomeGain went from limping into its last few million dollars of startup capital to being one of the leading real estate search sites. The company was eventually sold to a consortium of five giant newspaper companies, including the Washington Post.

When HomeGain’s management changed, the new bosses sold Wahl’s first neighborhood map data to Maponics for $40,000. Wahl had permission to keep selling and using the data for six months, according to court documents.

“They gave me $5,000,” Wahl says.

Wahl has continued to develop his data, refining the boundaries on his U.S. maps, and expanding internationally to Asian and European cities in 30 countries. His customers include Craigslist and Ask.com, and he gives away data at no charge to researchers, including those at the FDIC, and to epidemiologists working with the Centers for Disease Control to track the spread of disease.

“We aren’t getting rich off this, though clients do pay for the data,” Wahl says. “We try to get the data out everywhere we can, so we can see how people are using it — that’s very interesting. It’s about public service and the public good as much as making money.”

But the low price tag for Wahl’s maps is precisely what irks Maponics, which accuses Wahl, and his company, Factle, of offering the data at “fire-sale prices.”

Last year, Maponics contacted one of Wahl’s customers, Toursheet.com, and demanded the social place-marking site stop using Wahl’s data. “It allows … Toursheet to use a common map to show the attitude of the neighborhood, so people can have a real sense of community,” says founder Kyle Else. “Well, it did before I heard from Maponics…. They threatened my future development. I missed my window because of their threats, and I’m stuck in limbo until this is sorted out.”

Maponics filed suit in federal court in Los Angeles in November 2008 accusing Wahl of copyright infringement and unfair competition.

“We’re not out to put Bernt out of business,” says George Frost, Maponics’ attorney. “If they’ve got another product that isn’t related to our product, they’re free to sell it. But the software and information that went into it belong to us.”

Maponics CEO Darrin Clement has said in e-mails to Wahl’s customers that Wahl “stole” Maponics data. That’s prompted Wahl to countersue for defamation.

Wahl believes neighborhood boundaries are in the public domain. “I don’t know how anyone can say they own it,” Wahl muses. He argues there’s more at stake than just profits.

“This data literally saves lives,” says Wahl. “We could make more money at other jobs or selling the data for market value, but want we want to do is save lives and save the world. That starts at the neighborhood.”
