Yesterday, Zomato, a food ordering and restaurant finding company, announced security breach of more than 17 million accounts, via their official blog. A hacker operating under the alias nclay uploaded evidence to prove they had the stolen data — hashed passwords and emails — for sale, Hackread.com reported. Zomato later announced they contacted the hacker, who asked Zomato to organise a bug bounty programme.

The food ordering company, with 120 million monthly users, said the payment information of the users was not located with this data and was not leaked. Zomato said it uses PCI Data Security Standards.

As a security measure, all the passwords of the involved Zomato accounts were reset and all of the accounts were forcibly logged out from the application and website. The company said only hashed passwords were compromised.

Hashed passwords are encrypted and, per Zomato, every password had a different “salt”, for cryptographic salting was performed before hashing the original password. A “salt” is a random set of characters added before encryption to make decryption to obtain the original passkey more difficult.

The hashed password itself can not be used to access the account. In the blog post before contacting the hacker, saying “internal (human) security breach”, Zomato suggested this could have happened after a worker’s development account was hijacked. After contacting the hacker, and promising a bug bounty programme on Hackerone, they said, the hacker agreed and removed the stolen data which was put on sale on the dark web. Zomato said they are looking forward to working closely with the ethical hacker community on security vulnerabilities.

Cambridge, Massachusetts —

IBM’s T.J. Watson Research Center in Cambridge released a free tool March 25 for visualizing the changing history of a document or directory of documents, called history flow. The tool offers a variety of views of document histories, including a view that gives each revision equal importance, and a timeline view which displays each revision proportionally to how long it remained current. Each different editor who makes changes to the article has a distinct color, allowing for that editor’s text to be tracked over time.

The tool was first developed in 2003 by a collaboration between Fernanda B. Viégas of the MIT Media Lab and Martin Wattenberg and Kushal Dave of IBM. It was initially tested out on a large subset of the pages of Wikipedia, a free online encyclopedia project which preserves every change made to each of its articles. The resulting paper was drafted in the winter of 2003 and presented at a conference in April 2004; it remains the most comprehensive overview of the lifecycle of articles in an active wiki community. A year later, the history flow paper is still the most frequently cited source of statistics about the reversion of vandalism on Wikipedia.

The current tool is maintained by Martin Wattenberg and Jonathan Feinberg at IBM. It allows users to download the text and histories of the contents of any MoinMoin wiki, or to view the history of the contents of an entire directory of documents. The tool is free to download and use, but its code is not open source. The support for MoinMoin wikis comes via a plugin, so the tool may be extensible to the native interfaces of other wiki engines in the future.

In a 7-2 decision handed down on Monday, the US Supreme Court struck down California’s violent video game law and ruled that video games are protected speech covered by the First Amendment. The California law banned the sale and rental of violent video games to minors.

The underlying question was whether the violence in video games has the ability to affect children more than violence in other media, such as books, movies, plays and other forms of entertainment.

Justice Antonin Scalia, writing for the majority, said that depictions of violence have never been regulated by the US government. Thus violent videos are not to fall under government control as does pornography but is to be accorded the same First Amendment protections as other forms of entertainment. The sale of violent video games is not to be criminalized and California’s attempt to do so was “unprecedented and mistaken.” Scalia noted, referring to fairy tales, that “the books we give children to read—or read to them when they are younger—contain no shortage of gore.”

The beginning of the decision states, “Video games qualify for First Amendment protection. Like protected books, plays, and movies, they communicate ideas through familiar literary devices and features distinctive to the medium. And ‘the basic principles of freedom of speech…do not vary’ with a new and different communication medium.”

“The most basic principle—that government lacks the power to restrict expression because of its message, ideas, subject matter, or content, Ashcroft v. American Civil Liberties Union, 535 U. S. 564, 573—is subject to a few limited exceptions for historically unprotected speech, such as obscenity, incitement, and fighting words. But a legislature cannot create new categories of unprotected speech simply by weighing the value of a particular category against its social costs and then punishing it if it fails the test.”

The justices were not convinced by the existing research that the interactive nature of video games pose a greater risk to society because of their interactive nature. None of the results of the existing research put before the court showed that violent games cause violent behavior. “Psychological studies purporting to show a connection between exposure to violent video games and harmful effects on children do not prove that such exposure causes minors to act aggressively. Any demonstrated effects are both small and indistinguishable from effects produced by other media. Since California has declined to restrict those other media, e.g., Saturday morning cartoons, its video-game regulation is wildly under-inclusive, raising serious doubts about whether the State is pursuing the interest it invokes or is instead disfavoring a particular speaker or viewpoint.”

According to Nadine Kaslow, professor and chief psychologist at Emory University Department of Psychology and Grady Hospital, the evidence regarding the effects of violent video games is mixed. While there is evidence to suggest that exposure of children to violence results in more aggressive and less pro-social behavior, some studies show there is no negative effect, she said. She point out that toy guns were popular and parents monitored whether toy guns were allowed in the home.

This ruling does not prevent private retailers from placing restrictions on their sale of video games. The video game industry currently has its own rating system, much like that used for movies, and educates retailers in using the rating system to prevent minors from buying mature-rated games. According to PC World the industry’s compliance is better than that of other entertainment industries. Further, parental controls have been added to game consoles.

The view of the Entertainment Software Association that a better strategy is the education of parents rather than court battles.

A diverse group of approximately 25 people gathered at the Johnson County Library on Monday to participate in reference librarian Scott Vieira’s class, Wikiwhatia? Wikipedia.

Scott opened the session by sharing a disparaging quote from Robert McHenry (former editor-in-chief of Encyclopedia Britannica) comparing Wikipedia to a public restroom. He then shared a quote from Andrew Keen, author of The Cult of the Amateur, in which he stated Wikipedia is the blind leading the blind. Scott shared Wikipedia usage data from a 2007 Pew Internet study showing 36% of adults have consulted Wikipedia and that that Wikipedia receives 10,000-30,000 searches per second. Scott also pointed out that Wikipedia now has over two million articles in English alone (over nine million articles in 250 languages). So there is a discrepancy here, lots of critics and lots of use.

Scott then shared some historical information in order to provide a context for understanding Wikipedia. This included some important names and dates in the history of encyclopedias… including Pliny the Elder (23-79 C.E.) who published 37 Volumes of Natural History, and Joachim Sterck van Ringelbergh (c. 1499-1556) who first used the term encyclopedia, and then d’Alembert and Diderot who published 17 volumes of their French Encyclopedia from 1751-1765. Encyclopedia Britannica was first published in Scotland in serial format 1768-1771.

Scott also discussed more recent history, sharing a photo of Ward Cunningham –who is credited with being the inventor of wiki software. Wikipedia was founded on Jan 15, 2001 by Larry Sanger and Jimmy Wales. Sanger left Wikipedia in 2002 and founded Citizendium in 2007 a complementary project which now has 4500 articles.

After the historical perspective, the class moved into using Wikipedia. Everyone in the audience had used Wikipedia. The class explored the content of Wikipedia, realising there is a whole lot going on. Scott demonstrated that the article about “frogs” for example, is semi-protected. The “history of science” article was examined, including the history of changes. Discussion covered how people contribute, who contributes and edits. The group also talked about Wikipedia bots, which aid in routine tasks in a semi-automated or automated fashion.

A discussion about teachers, school media specialists and students regarding their use of Wikipedia ensued. Some teachers and school media specialists are negative about Wikipedia, but Scott’s hope is that they will use it to start a discussion about the need to evaluate and critically think about information (even when it’s from more traditionally reviewed and edited sources).

An unanswered question from an audience member was, “What was the first Wikipedia article?”

Discussion topics from Scott to audience were as follows:

• Do you think Wikipedia is less accurate than published resources and how important is that accuracy to you?
• How do we determine authority on a subject? How important is it that an article be written by an expert? How is Wikipedia changing our idea of what an authority is?
• Currency – the ability to publish immediately – what are the advantages and what are the disadvantages?
• What do we think about the content selection in Wikipedia?
• Should Wikipedia be used by librarians?
• What do you think about the future of Wikipedia?

The Huffington Post reported Friday that U.S. presidential candidate Buddy Roemer received a $25 campaign donation from an individual listed as ‘Homer Simpson’; the same name as the main character of the long running animated television series The Simpsons. Along with the name, the donor also shares the cartoon character’s place of residence and employment. He claims to live at 742 Evergreen Terrace, and to work as Safety Inspector at Springfield Nuclear Power Plant.

The Huff Post discovered the July 31 donation while analyzing Roemer’s Federal Election Commission records. After being notified, Roemer’s campaign manager, Carlos Sierra, responded “Oh my God. That is too funny”. He added that the campaign uses “one of the best accountants in the business,” and that he would personally find out who actually made the donation. Sierra noted that “we do not accept anonymous donations”.

Roemer, who previously served as a member of the House of Representatives (1981–1988) and Governor of Louisiana (1988–1992), has been running for the Republican Party’s presidential nomination since earlier this year. However, he has failed to receive invitations to any presidential debates.

Roemer, who recently expressed his support for the Occupy Wall Street protests, has focused his campaign on finance reform, and has limited individual contributions to $100. In the third quarter of 2011, he raised $138,000.

Wikinews contacted Carlos Sierra yesterday for an update on the matter. He explained, “I reached out to the individual and he was very apologetic. I have the correct information now and will turn it over to our compliance officer.”

On January 1 2007, Slovenia officially joined the Eurozone and adopted the euro as its new official currency. At the same time, Slovenian euro coins, which were available as a “starter kit” from December 15, became legal tender everywhere in the Eurozone.

A period of dual circulation, when both the former currency, the tolar and the euro will be accepted, will only last until January 14. All banks are going to exchange tolars into euros at the official rate of 239.64 SIT per 1 EUR at no commission until March 1, 2007. After that date it will be possible to exchange tolar banknotes (unlimited) and coins (until 2016) only at the Bank of Slovenia.

Most ATMs already dispense euro banknotes with the rest to follow in the following days. Commercial banks automatically converted all tolar accounts into euros and online banking systems will be accessible to their users again on January 3. Even though January 1 and 2 are non-working days in Slovenia, many banks will be opened from 10:00 to 14:00 on both days, available only for one service: exchanging tolars to euros and larger euro banknotes into smaller units.
