A concentrated campaign of price manipulation may have accounted for at least half of the increase in the price of Bitcoin and other big cryptocurrencies last year, according to a paper released on Wednesday by an academic with a history of spotting fraud in financial markets. From a report, first shared to us by reader davidwr: The paper by John Griffin, a finance professor at the University of Texas, and Amin Shams, a graduate student, is likely to stoke a debate about how much of Bitcoin's skyrocketing gain last year was caused by the covert actions of a few big players, rather than real demand from investors. Many industry players expressed concern at the time that the prices were being pushed up at least partly by activity at Bitfinex, one of the largest and least regulated exchanges in the industry. The exchange, which is registered in the Caribbean with offices in Asia, was subpoenaed by American regulators shortly after articles about the concerns appeared in The New York Times and other publications. Mr. Griffin looked at the flow of digital tokens going in and out of Bitfinex and identified several distinct patterns that suggest that someone or some people at the exchange successfully worked to push up prices when they sagged at other exchanges. To do that, the person or people used a secondary virtual currency, known as Tether, which was created and sold by the owners of Bitfinex, to buy up those other cryptocurrencies.Read Replies (0)

An anonymous reader writes: Netflix's engineering team has an insightful post today that looks at how the industry is handling video coding; the differences in their methodologies; and the challenges new comers face. An excerpt, which sums up where we are: "MPEG-2, VC1, H.263, H.264/AVC, H.265/HEVC, VP9, AV1 -- all of these standards were built on the block-based hybrid video coding structure. Attempts to veer away from this traditional model have been unsuccessful. In some cases (say, distributed video coding), it was because the technology was impractical for the prevalent use case. In most other cases, however, it is likely that not enough resources were invested in the new technology to allow for maturity. "Unfortunately, new techniques are evaluated against the state-of-the-art codec, for which the coding tools have been refined from decades of investment. It is then easy to drop the new technology as "not at-par." Are we missing on better, more effective techniques by not allowing new tools to mature? How many redundant bits can we squeeze out if we simply stay on the paved path and iterate on the same set of encoding tools?"Read Replies (0)

Gene Park, writing for The Washington Post (shared by numerous readers): In the Nintendo universe, Waluigi is supposed to be as villainous as his cartoonish mustache and perpetual frown would suggest. But what made him that way? Perhaps it is Nintendo's insistence on humiliating the character in front of his friends and the general public. On Tuesday for the Electronic Entertainment Expo, Nintendo announced new details on the much-anticipated Super Smash Bros. Ultimate for its Switch console. The 25-minute presentation was long on details. For one thing, the latest game includes every single playable character in the fighting-game franchise's 19-year history. It seemed to exceed fan expectations, except for fans of the meme-ready Waluigi. Waluigi, again, was snubbed by Nintendo. He will not be a playable character in the new game. Waluigi has traveled a long road. Once he was hated by Nintendo fans, who listed him highly among gaming's most annoying characters. His origin story is unimpressive. Waluigi is simply a bizarro version of Mario's less famous but more charming brother Luigi. In his 18-year existence as a minor character, he's had virtually no back story. But that blank canvas ended up becoming Waluigi's greatest gift. Since he stood for nothing, supporters could project their wildest hopes unto him, like Barack Obama in 2008 but actually good at golf. He can be described in a single website as anyone from a "true nowhere man" to "the logical end point of capitalism" and the "triumph of capital over creativity." In other words, Waluigi became the perfect meme fodder.Read Replies (0)

An anonymous reader quotes a report from Eyewitness News: Chile's Senate has passed a bill that will prohibit the use of plastic bags in stores, with a vote in their House of Representatives overwhelmingly in favor of the measure, with 134 supporting the bill and one abstention. According to The Independent, the new law would give large retailers one year to phase out the use of plastic bags, and smaller businesses two years. This makes Chile the first country in the Americas to ban plastic bags, and officially recognize how important such a ban would be in the effort to reduce unnecessary single-use plastic waste.
At first, the measure was only meant to ban plastic bags in Patagonia, but it was approved by both the senate and president for the entire country. The Association of Plastic Industries registered Chile as using 3,400 million plastic bags per year, or 200 per person. Telesur reports that the Minister of the Environment, Marcela Cubillos, said the country needs a larger cultural change for people to start replacing plastic with reusable bags.Read Replies (0)

Facebook will now let you file a complaint about businesses you've had a problem with if you bought something after clicking on one of their ads. If enough people complain about a business, it could lead to Facebook banning the company from running ads. The Verge reports: The new policy is rolling out globally starting today, and it's meant to help Facebook fight back against another type of advertising abuse on its platform. Facebook says it's trying to combat "bad shopping experiences," which can cost customers and make them frustrated with Facebook, too. Facebook is particularly interested in a few problem areas: shipping times, product quality, and customer service. This isn't just a matter of misleading advertising: if a company regularly provides bad service, products that don't meet buyers' expectations, or just frustrates consumers, they risk getting in trouble with the platform.
It appears that Facebook will send notifications to users to ask about their experience if it detects that they've purchased something after clicking on an ad. You'll also be able to find those companies and leave feedback on the Ads Activity page. Facebook says it will inform businesses about negative feedback and try to pinpoint problems that a large number of customers are having. If customer feedback doesn't improve after a warning, Facebook will eventually start to limit how many ads a company can run. If it continues long enough, they can be banned.Read Replies (0)

According to estimates from media agency Zenith, next year, for the first time, people will spend more time using the internet than watching TV. People will spend an average of 170.6 minutes a day, or nearly three hours, using the internet in 2019. That's a tad more than the 170.3 minutes they're expected to spend watching TV. Quartz reports: Zenith measured media by how they are transmitted or distributed, such as broadcasts via TV signals and newspapers in print. Watching videos on the web through platforms like Netflix and YouTube, or reading a newspaper's website, counted as internet consumption. Nearly one-quarter of all media consumption across the globe will be through mobile this year, up from 5% in 2011. The average person will spend a total of about eight hours per day consuming media in its many forms this year, Zenith forecasts.
In some parts of the world, TV will remain on top -- for now. Zenith forecasted media consumption through 2020 and did not expect the internet to overtake TV in Europe, Latin America, and the whole of North America in that time. In the U.S., it was projected to surpass TV in the U.S. in two years.Read Replies (0)

Google is rolling out offline Neural Machine Translation (NMT) support for 59 languages in the Translate apps. Some of the supported languages include Arabic, Chinese, English, German, Japanese, Spanish, French, and Korean (TechCrunch has a full list of the languages in their report). From the report: In the past, running these deep learning models on a mobile device wasn't really an option since mobile phones didn't have the right hardware to efficiently run them. Now, thanks to both advances in hardware and software, that's less of an issue and Google, Microsoft and others have also found ways to compress these models to a manageable size. In Google's case, that's about 30 to 40 megabytes per language. Users will see the updated offline translations within the next few weeks.Read Replies (0)

Earlier today, Nintendo announced during its E3 press conference that Epic Games' Fortnite would be coming to the Switch console. Unfortunately, when Epic Games PR representative Nick Chester confirmed cross-play compatibility, the PS4 wasn't on the list. The Switch version of Fortnite will only support cross-play with Xbox One, PC, Mac, and mobile. The Verge reports: That aligns with past cross-play implementations between Xbox One, PS4, PC, and mobile, with Sony blocking other console platforms from playing with its own. You can cross-play between PS4, mobile, and PC. Unfortunately, this also suggests that PS4 players of Fortnite won't be able to log in to their Epic accounts on the Switch, meaning you won't be able to have any weekly progress carry over or gain access to any of your skins or emotes. This is because your Epic account is tied up with your PSN username in most cases. For instance, you can't log in to an Epic account tied to PSN on the Xbox One version of Fortnite, and it sounds like the same will be true for the Switch.Read Replies (0)

An anonymous reader quotes a report from The Register: Yahoo's U.K. limb has finally been handed a $334,300 (250,000 GBP) fine for the 2014 cyber attack that exposed data of half a million Brit users. Today, the Information Commissioner's Office issued Yahoo U.K. Services Ltd a $334,300 (250,000 GBP) fine following an investigation that focused on the 515,121 U.K. accounts that the London-based branch of the firm had responsibility for. The ICO said "systemic failures" had put user data at risk as the U.K. arm of Yahoo did not take appropriate technical and organizational measures to prevent a data breach of this size.
In particular, the watchdog said there should have been proper monitoring systems in place to protect the credentials of Yahoo employees who could access customer's data, and to ensure that instructions to transfer very large quantities of personal data from Yahoo's servers would be flagged for investigation. It also noted that, as a data controller, Yahoo U.K. services Ltd had a responsibility to ensure its processors -- in this case Yahoo, whose U.S. servers held the data on U.K. users -- complied with data protection standards.Read Replies (0)

Apple has updated its App Store guidelines to close a loophole that let app makers store and share data without many people's consent. The practice has "been employed for years," reports Bloomberg. "Developers ask users for access to their phone contacts, then use it for marketing and sometimes share or sell the information -- without permission from the other people listed on those digital address books." From the report: As Apple's annual developer conference got underway on June 4, the Cupertino, California-based company made many new pronouncements on stage, including new controls that limit tracking of web browsing. But the phone maker didn't publicly mention updated App Store Review Guidelines that now bar developers from making databases of address book information they gather from iPhone users. Sharing and selling that database with third parties is also now forbidden. And an app can't get a user's contact list, say it's being used for one thing, and then use it for something else -- unless the developer gets consent again. Anyone caught breaking the rules may be banned.
While Apple is acting now, the company can't go back and retrieve the data that may have been shared so far. After giving permission to a developer, an iPhone user can go into their settings and turn off apps' contacts permissions. That turns off the data faucet, but doesn't return information already gathered.Read Replies (0)

Some of Africa's oldest and biggest baobab trees have abruptly died, wholly or in part, in the past decade, according to researchers. From a report: The trees, aged between 1,100 and 2,500 years and in some cases as wide as a bus is long, may have fallen victim to climate change, the team speculated. "We report that nine of the 13 oldest ... individuals have died, or at least their oldest parts/stems have collapsed and died, over the past 12 years," they wrote in the scientific journal Nature Plants, describing "an event of an unprecedented magnitude." "It is definitely shocking and dramatic to experience during our lifetime the demise of so many trees with millennial ages," said the study's co-author Adrian Patrut of the Babes-Bolyai University in Romania. Among the nine were four of the largest African baobabs. While the cause of the die-off remains unclear, the researchers "suspect that the demise of monumental baobabs may be associated at least in part with significant modifications of climate conditions that affect southern Africa in particular." Further research is needed, said the team from Romania, South Africa and the United States, "to support or refute this supposition."Read Replies (0)

An anonymous reader quotes a report from Ars Technica: Senate leaders agreed Monday to include language in the annual defense spending bill that would reverse the Trump administration's decision to save Chinese telecommunications company ZTE after it was caught violating the terms of a 2017 penalty agreement by making illegal sales to Iran and North Korea. The language will be part of an amendment in the 2019 National Defense Authorization Act, a $716 billion defense policy bill, H.R. 5515 (115).
If the Senate amendment becomes law, it would automatically reinstate the seven-year prohibition until Trump has certified to Congress that ZTE has met certain conditions. It also would ban all U.S. government agencies from purchasing or leasing telecommunications equipment and/or services from ZTE, a second Chinese telecommunications firm, Huawei, or any subsidiaries or affiliates of those two companies. The amendment language "prohibits the federal government from doing business with ZTE or Huawei or other Chinese telecom companies" and puts the company back on the sanctions list and "holds ZTE accountable for violating their previous commitment," Cotton said. The senators supporting the amendment include Democratic minority leader Chuck Schumer and two Republican Senators -- Sen Tom Cotton (R-Ark.) and Sen. Marco Rubio (R-Fla.). "I and obviously every other senator believes the death penalty is the appropriate punishment for their behavior," Sen. Tom Cotton (R-Ark.) told reporters after Ross briefed senators on the department's latest ZTE action. "They're a repeat bad actor that should be put out of business. For eight years, ZTE was able to run wild and be able to become the fourth-largest telecom company in the world." If the Senate amendment becomes law, "I would expect there wouldn't be a ZTE," Cotton added.Read Replies (0)

A federal judge said Tuesday that AT&T's $85.4 billion purchase of Time Warner is legal, clearing the path for a deal that gives the pay-TV provider ownership of cable channels such as HBO and CNN as well as film studio Warner Bros. From a report: U.S. District Judge Richard Leon announced his decision in a packed courtroom, ruling that antitrust enforcers at the Justice Department had not proven their case against the merger. The decision, in one of the biggest antitrust cases in decades, is a milestone victory for AT&T as it looks to reposition itself in a rapidly evolving media landscape. Its deal for Time Warner, valued at roughly $80 billion, has been pending since October 2016. The acquisition means AT&T will be the nation's top pay-TV distributor, through its ownership of DirecTV, as well as the owner of some of the country's most sought-after channels: Time Warner's Turner networks -- including CNN, TBS and TNT -- as well as HBO, the most popular U.S. premium network.Read Replies (0)

An anonymous reader writes: According to a report released yesterday, criminal groups have mined an approximate total of 798,613.33 Monero coins (XMR) using malware on infected devices. That's over $108 million in US currency, just from coin-mining operations alone. This sum also represents around 5% of all the Monero currently in circulation -- 15,962,350 XMR. Furthermore, during the past year, infected devices were responsible for 19,503,823.54 hashes/second, which is roughly 2% of the entire hashing power of the Monero network. The total hashrate of roughly 19MH/s would result in approximately $30,443 per day based on today's current exchange rates and network difficulty," researchers said. "Similarly, the top three hash-rates will mine approximately $2,737, $2,022 and $1,596 per day, respectively."Read Replies (0)
