An anonymous reader shares a report: The $14 billion network of levees and floodwalls that was built to protect greater New Orleans after Hurricane Katrina was a seemingly invincible bulwark against flooding. But now, 11 months after the Army Corps of Engineers completed one of the largest public works projects in world history, the agency says the system will stop providing adequate protection in as little as four years because of rising sea levels and shrinking levees. The growing vulnerability of the New Orleans area is forcing the Army Corps to begin assessing repair work, including raising hundreds of miles of levees and floodwalls that form a meandering earth and concrete fortress around the city and its adjacent suburbs.

"These systems that maybe were protecting us before are no longer going to be able to protect us without adjustments," said Emily Vuxton, policy director of the Coalition to Restore Coastal Louisiana, an environmental group. She said repair costs could be "hundreds of millions" of dollars, with 75% paid by federal taxpayers. "I think this work is necessary. We have to protect the population of New Orleans," Vuxton said. The protection system was built over a decade and finished last May when the Army Corps completed a final component that involves pumps.

The consumer version of Blackberry Messenger is shutting down May 31. CNET reports: Emtek, the company BlackBerry partnered with in 2016 to run the consumer version of the messaging app, said in a blog post Thursday that the technology industry is "very fluid" and despite "substantial efforts," users have moved on to other platforms. "We poured our hearts into making this a reality, and we are proud of what we have built to date," Emtek said.

Mark Wilson, BlackBerry's chief marketing officer, said that though the company is disappointed, BBM users won't be without a secure messaging platform. They can now go to the Google Play store to download BBMe, the enterprise version of the app that BlackBerry continues to run. The app will be free the first year. Then a 6-month subscription will cost $2.49. BlackBerry is working on an iOS app.

An anonymous reader quotes a report from The Guardian: It's just as you suspected; the information age has changed the general attention span. A recently published study from researchers at the Technical University of Denmark suggests the collective global attention span is narrowing due to the amount of information that is presented to the public. Released on Monday in the scientific journal Nature Communications, the study shows people now have more things to focus on -- but often focus on things for short periods of time.

The researchers studied several modes of media attention, gathered from several different sources, including (but not limited to): the past 40 years in movie ticket sales; Google books for 100 years; and more modernly, 2013 to 2016 Twitter data; 2010 to 2018 Google Trends; 2010 to 2015 Reddit trends; and 2012 to 2017 Wikipedia attention time. The researchers then created a mathematical model to predict three factors: the "hotness" of the topic, its progression throughout time in the public sphere and the desire for a new topic, said Dr Philipp Hovel, an applied mathematics professor of University College Cork in Ireland. The empirical data found periods where topics would sharply capture widespread attention and promptly lose it just as quickly, except in the cases of publications like Wikipedia and scientific journals. For example, a 2013 Twitter global trend would last for an average of 17.5 hours, contrasted with a 2016 Twitter trend, which would last for only 11.9 hours.

Amazon announced today that it will close its marketplace in China in the coming months, meaning Amazon customers in the country will no longer be able to buy goods from Chinese merchants. "Amazon did not explain why it was withdrawing its marketplace service, saying only it will instead focus on selling goods shipped from other countries into China," reports CNN. From the report: "We are notifying sellers we will no longer operate a marketplace on Amazon.cn, and we will no longer be providing seller services on Amazon.cn effective July 18," the company said in a statement. Amazon's platform competes for Chinese sellers with Tmall, owned by the country's e-commerce leader Alibaba.

Users logging onto Amazon's Chinese site after July 18 will see products sold from its global store, the company said. "Over the past few years, we have been evolving our China online retail business to increasingly emphasize cross-border sales, and in return we've seen very strong response from Chinese customers," Amazon said. It will retain its other operations in China, such as cloud computing services. It will also continue to sell its Kindle e-readers and content in the country. "Amazon's commitment to China remains strong. We have built a solid foundation here in a number of successful businesses and we will continue to invest and grow in China," the company added.

An anonymous reader quotes a report from Bloomberg: More cities in Asia and Europe are seeking to link up with each other and the global air travel network. The Mitsubishi Regional Jet, the first airliner built in Japan since the 1960s, began certification flights last month in Moses Lake, Washington, to satisfy that demand. Mitsubishi Heavy Industries Ltd.'s new airliner is testing the skies just as rivals are moving to sell off their manufacturing operations for jets with up to 160 seats. Boeing is set to buy 80 percent of the Embraer SA's commercial operations in a joint venture, while Bombardier last year sold control of its C Series airliner project to Airbus SE and is exploring "strategic options" for its regional-jet operations. At stake, particularly in the market for jets with fewer seats, is $135 billion in sales in the two decades through 2037, according to industry group Japan Aircraft Development Corp.

With few seats and smaller fuselages, regional jets are a different class of aircraft from larger narrow-body planes such as Boeing's 737 or Airbus's A320. The MRJ has a range of about 2,000 miles, while a smaller variant can haul up to 76 people for about the same distance. A longtime supplier of aircraft components to Boeing, Mitsubishi Heavy is developing the MRJ to emerge from its customer's shadow. After spending at least $2 billion over more than a decade, the manufacturer is looking to get its jet certified and start deliveries to launch partner ANA Holdings. Mitsubishi expects to have the plane ready for customers next year, a timetable that will test the company, said Mitsubishi Aircraft President Hisakazu Mizutani.

Netflix is establishing an NYC production hub that will include six sound stages in Brooklyn and an expanded office in Manhattan's Flatiron District. "It should create 'hundreds of jobs' (including 127 executive, marketing and production development roles) over the next five years, and should foster up to $100 million in investments, according to Governor Cuomo," reports Engadget. From the report: The sound stages will also have the capacity for "thousands" of jobs, Cuomo said, although that's likely to vary widely based on what's in production at any given time. Not surprisingly, there are financial incentives attached to the move. The state is offering up to $4 million in tax credits over 10 years, although those are contingent on Netflix's ability to both create the 127 promised office jobs and keep the 32 existing positions.

AmiMoJo writes: It's time to buy a new chair so I'm turning to Slashdot for recommendations. The Herman Miller Aeron seems to be the go-to, much like the Model M for keyboards, but I've heard that there are some other good options on the market.

I need something that is comfortable and durable -- too many chairs get squeaky and loose because I can't sit still and keep shifting my weight around. Many are difficult to maintain as well, e.g. the screws attacking the back are often under plastic attached with very stiff clips so you can't easily give them a quick tighten. What does Slashdot recommend for my posterior? It's been more than a decade since readers sought recommendations for a quality chair for desktop coding, or back-friendly chairs. In fact, it's been almost two decades since a user inquired about the perfect computer chair. Hopefully office chairs have improved in quality/design since then...

An anonymous reader quotes a report from Ars Technica: FCC Chairman Ajit Pai has proposed denying China Mobile USA's application to offer telecom services in the U.S., saying the Chinese government-owned company poses a security risk. The FCC is scheduled to vote on an order to deny the application at its open meeting on May 9, and Pai yesterday announced his opposition to China Mobile entering the U.S. market. "After reviewing the evidence in this proceeding, including the input provided by other federal agencies, it is clear that China Mobile's application to provide telecommunications services in our country raises substantial and serious national security and law enforcement risks," Pai said. "Therefore, I do not believe that approving it would be in the public interest. I hope that my colleagues will join me in voting to reject China Mobile's application."

China Mobile filed its application in 2011, and has repeatedly complained about the government's lengthy review process. According to Pai's announcement, China Mobile's application sought authority "to provide international facilities-based and resale telecommunications services between the U.S. and foreign destinations." In simpler terms, the company was seeking "a license to connect calls between the United States and other nations" and "was not seeking to provide domestic cell service and compete in the country with businesses like AT&T and Verizon," The New York Times wrote yesterday. An FCC official told reporters that such calls "could be intercepted for surveillance and make the domestic network vulnerable to hacking and other risks," the Times wrote.

MoviePass users apparently hit the exits en masse after it scaled back the number of movies users could see each month. From a report: The flailing cinema-subscription provider has seen its subscriber rolls plunge from a peak of more than 3 million to just 225,000 in under a year, according to a new report. The numbers were reported by Business Insider, which cited "internal data" it had obtained. Asked for comment, a MoviePass spokeswoman declined to confirm the subscriber figure. In June 2018, MoviePass claimed it had signed up more than 3 million subscribers for its $9.95 monthly plan, which let customers see one movie every single day. But that proved unsustainable, and MoviePass was forced to change that to a three-movies-per-month plan. In August 2018, MoviePass began to convert subscribers on annual subscription plans to the three-movies-per-month subscription plan, by giving annual subscribers the option to either cancel or refund their annual subscription or continue on the new three-movies-per-month subscription plan.

If we're going to avoid the worst consequences of climate change, we'll need an energy revolution. But there's a big problem. Making that future a reality will, among other things, require a lot of batteries: batteries to charge our electric cars; batteries to store solar power collected while the sun's up and wind power harnessed when it's gusty out. And as a new report by researchers at the University of Technology Sydney warns, that's likely to drive demand for the metals used to build green batteries -- as well as wind turbines and solar panels -- through the roof.

From a report: In other words the clean tech boom is, at least in the short term, likely to fuel a mining boom. And that won['t come without cost. "We already know about the environmental, social, and human rights impacts extraction is posing to front line communities right now," Payal Sampat, mining program director at Earthworks, which commissioned the new report, told Earther. "It's kind of unimaginable to think about... how it would be considered sustainable to scale up those impacts that many fold and still be reaping benefits."

Much like our smartphones and computers, the high-tech energy infrastructure of tomorrow requires a host of metals and minerals from across the periodic table and the planet. The lithium-ion batteries used in EVs and energy storage require not just lithium, but often cobalt, manganese, and nickel. Electric vehicle engines rely on rare earths, as do the permanent magnet-based generators inside some wind turbines. Solar panels gobbles up a significant share of the world's supply of tellurium, and gallium, along with a sizable fraction of mined silver and indium. Most renewable technologies demand heaps of copper and aluminum.

Citing lackluster financial performance, IBM is halting development and sales of a product that uses its Watson AI software to help pharmaceutical companies discover new drugs, news outlet Stat reported on Thursday, citing a person familiar with the company's internal decision-making. From the report: The decision to shut down sales of Watson for Drug Discovery marks the highest-profile retreat in the company's effort to apply artificial intelligence to various areas of health care. Last year, the company scaled back on the hospital side of its business, and it's struggled to develop a reliable tool to assist doctors in treating cancer patients. In a statement, an IBM spokesperson said, "We are focusing our resources within Watson Health to double down on the adjacent field of clinical development where we see an even greater market need for our data and AI capabilities."

Last month, Facebook disclosed that hundreds of millions of users on its platform had their account passwords stored in plain text -- in some cases going back to 2012 -- and searchable by thousands of Facebook employees. Today, the company quietly updated that blog post to reveal that Instagram users are also impacted. It said, in the update: Since this post was published, we discovered additional logs of Instagram passwords being stored in a readable format. We now estimate that this issue impacted millions of Instagram users. We will be notifying these users as we did the others. Our investigation has determined that these stored passwords were not internally abused or improperly accessed.

An internet milestone known as "768k Day" is getting closer and some network administrators are shaking in their boots fearing downtime caused by outdated network equipment. From a report: The fear is justified, and many companies have taken precautions to update old routers, but some cascading failures are still predicted. The term 768k Day comes from the original mother of all internet outages known as 512k Day. [...] Many legacy routers received emergency firmware patches that allowed network admins to set a higher threshold for the size of the memory allocated to handle the global BGP routing table. Most network administrators followed documentation provided at the time and set the new upper limit at 768,000 -- aka 768k.

CIDR Report, a website that keeps track of the global BGP routing table, puts the size of this file at 773,480 entries; however, their version of the table isn't official and contains some duplicates. A Twitter bot named BGP4-Table, which has also been tracking the size of the global BGP routing table in anticipation of 768K Day, puts the actual size of the file at 767,392, just a hair away from overflowing. ZDNet spoke today with Aaron A. Glenn, a networking engineer with AAGICo Berlin, and Jim Troutman, Director at the Northern New England Neutral Internet Exchange (NNENIX). Both estimate 768K Day happening within the next month. But unlike many network admins, they don't expect the event to cause internet-wide outages like in 2014. However, both Glenn and Troutman expect some companies and smaller, local ISPs to be affected. "I would be mildly surprised if there was any interruption or outage at any real scale," Glenn told ZDNet.

Google's Chrome browser will get a Reader Mode, similar to the one found in competing browsers like Firefox and the old Microsoft Edge. From a report: The feature is currently under development, but Chrome Canary users can test it starting today. Chrome's Reader Mode will work by stripping pages of most of their useless content, such as ads, comments sections, or animations, and leave a bare-bones version behind, showing only titles, article text, and article images. Work on the feature started in February this year when Google engineers began porting the "simplified view" offered by Chrome on Android to desktop editions. Today is the first day that a fully-functional Reader Mode is active in Chrome's desktop versions -- via Google Chrome Canary distributions. To test Chrome's upcoming Reader Mode, users must first visit the chrome://flags/#enable-reader-mode section in their Chrome Canary version, and enable the Reader Mode option.

Former Google CEO Eric Schmidt in a new interview rejected the notion that Capitol Hill has a role to play in regulating big tech companies, breaking with Facebook CEO Mark Zuckerberg's recent willingness to work with lawmakers. From a report: "The problem is if you write a rule, inevitably, you fix the solution on a specific solution, but the technology moves so quickly," Schmidt says. "It's generally better to let the tech companies do these things," he adds. Schmidt, who ran Google from 2001 to 2011, acknowledged that over his tenure the company did not understand the scale or severity of problems originating from its products. But since then, the company has addressed the issues, he said. "Our response has, in my view, been very strong," he said. "Today, we have all sorts of software that enforces policies of one kind or another. And people complain about the rules, but the fact of the matter is the rules are published."

[...] Schmidt suggested that even if Congress does pass new regulations on tech companies, issues will continue to originate on tech platforms because the sites display unpredictable human conduct. Content moderators and other employees need to ensure that users abide by the rules of a given platform, he said. "All of these platforms that are human centric will have to have a component of them, which is...watching what the users are doing and making sure they're consistent with their terms of service and the law," he says. "These issues are ongoing, because these are human-based systems," he says. "And so humans will continue to use them. They will continue to do unexpected things. There will continue to be surprises."

Canonical today announced the release of Ubuntu 19.04 "Disco Dingo." With Linux 5.0 and GNOME 3.32, Disco Dingo features performance improvements and visual tweaks. Whether or not you upgrade, Disco Dingo lays the groundwork for future long term support releases of Ubuntu. From a report: Keep in mind, version 19.04 is not LTS (Long Term Support), meaning it is only supported until January 2020. "Ubuntu 19.04 introduces GNOME 3.32 with higher frame rates, smoother startup animations, quicker icon load times and reduced CPU+GPU load. Fractional scaling for HiDPI screens is now available in X-org and Wayland. Installing Ubuntu on VMWare will automatically install open-vm-tools for bi-directional clipboard, easy sharing of files and graceful power state management," says Canonical. The Ubuntu-maker further says, "In Ubuntu 19.04, multiple instances of the same snap can be installed for CI/CD, testing or phased rollouts. For example, two versions of a database or two versions of the golang compiler can be installed at the same time. Snap epochs control when and how data migration happens between major version upgrades."

Google said today it will start giving European Union smartphone users a choice of browsers and search apps on its Android operating system, in changes designed to comply with an EU antitrust ruling. From a report: Starting Thursday and following a software update, users in the EU opening Google's mobile app store will be presented with a choice of alternatives to Google search and Chrome. The Alphabet unit said options will vary by market, but Microsoft's Bing and Norway's Opera are notable competitors in the European search and browser market respectively.

The changes could help Google avoid additional fines after being scrutinized by the EU for almost a decade. The European Commission, the bloc's antitrust body, last year fined Google $4.8 billion for strong-arming device makers into pre-installing its Google search and Chrome browser, giving it a leg up because users are unlikely to look for alternatives if a default is already preloaded. The EU ordered Google to change that behavior and threatened additional fines if it failed to comply. In a statement, FairSearch, a group that includes Czech search engine Seznam.cz and Oracle, rejected the changes as insufficient. "It does nothing to correct the central problem that Google apps will remain the default on all Android devices," the group said. FairSearch filed one of the first complaints to the EU on Android.

Amazon and Google have worked out their differences. On Thursday, they announced that official YouTube app will soon make a return to Fire TV devices and Fire TV Edition smart TVs. Additionally, Prime Video app will be coming to Chromecast and Chromecast built-in devices. "In addition, Prime Video will be broadly available across Android TV device partners, and the YouTube TV and YouTube Kids apps will also come to Fire TV later this year," Amazon said.

An anonymous reader quotes a report from VentureBeat: In a step toward its goal of building out a data science development stack for web browsers, Mozilla today detailed Pyodide, an experimental Python project that's designed to perform computation without the need for a remote kernel (i.e., a program that runs and inspects code). As staff data engineer Mike Droettboom explained in a blog post, it's a standard Python interpreter that runs entirely in the browser. And while Pyodide isn't exactly novel -- projects like Transcrypt, Brython, Skulpt, and PyPyJs are among several efforts to bring Python to browsers -- it doesn't require a rewrite of popular scientific computing tools (like NumPy, Pandas, Scipy, and Matplotlib) to achieve adequate performance, and its ability to convert built-in data types enables interactions among browser APIs and other JavaScript libraries.

Pyodide is built on WebAssembly, a low-level programming language that runs with near-native performance, and emscripten (specifically a build of Python for emscripten dubbed "cpython-emscripten"), which comprises a compiler from C and C++ to WebAssembly and a compatibility layer. Emscripten additionally provides a virtual file system (written in JavaScript) that the Python interpreter can use, in which files disappear when the browser tab is closed. To use Pyodide, you'll need the compiled Python interpreter as WebAssembly, JavaScript from emscripten (which provides the system emulation), and a packaged file system containing the files required by the Python interpreter. Once all three components are downloaded, they'll be stored in your browser's cache, obviating the need to download them again. The report notes that "the Python interpreter inside the JavaScript virtual machine runs between one to 12 times slower in Firefox and up to 16 times slower on Chrome."

Facebook is working on a voice assistant to rival the likes of Amazon's Alexa, Apple's Siri and the Google Assistant, CNBC reported Wednesday, citing people familiar with the matter. From the report: The tech company has been working on this new initiative since early 2018. The effort is coming out of the company's augmented reality and virtual reality group, a division that works on hardware, including the company's virtual reality Oculus headsets. A team based out of Redmond, Washington, has been spearheading the effort to build the new AI assistant, according to two former Facebook employees who left the company in recent months. The effort is being lead by Ira Snyder, director of AR/VR and Facebook Assistant. That team has been contacting vendors in the smart speaker supply chain, according to two people familiar. It's unclear how exactly Facebook envisions people using the assistant, but it could potentially be used on the company's Portal video chat smart speakers, the Oculus headsets or other future projects.
