Reader joshtops shares a report: Apps are getting bigger in size, in part because developers add new features, something many users obviously appreciate, developers say. "Apps are getting bigger because iOS devices are more powerful, and developers are building more and more complex things for them without considering the impact the size will have around the world," developer Stephen Troughton-Smith tells Gadgets 360. But in part, it is also happening because developers are being careless, and adding more than one instance of files, Troughton-Smith added. "So Facebook, Twitter, and other large companies have perhaps tens or hundreds of people building their iOS apps. A lot of the components for these apps are developed independently as components, or frameworks. For each additional component you glue together into an app, there is some overhead," he explained. "Some of the teams will duplicate functionality some other team wrote. Images and other resources end up being duplicated." The high-resolution image assets that developers are required to add also contributes to the size of an app, two India-based developers, and Peter Steinberger, founder and CEO of PSPDFKit, a dev kit that is used by several popular PDF apps, told Gadgets 360. Apple can itself take some blame, too. Developers using Apple's Swift language, which the company introduced in 2014, are required to add several components to their apps that make them heavier. "Apple's new Swift language, for example, requires a bunch of components to be embedded each time it's used, because it's not yet 'ABI stable,'" Troughton-Smith explained. This means developers need to embed the versions of libraries they've developed against, and not count on the one available on the system. Another developer who didn't want to be identified said a typical app built with Swift language requires as many as 30 Swift runtime libraries to be stuffed within the app. On top of this, he added, "you will be surprised at just how many apps use common code found at places like GitHub. Developers often don't care about removing the bits that wasn't relevant to their app," he added.

Slashdot's blast-from-the-past department:
Jonathan Saul reports via Reuters: The risk of cyber attacks targeting ships' satellite navigation is pushing nations to delve back through history and develop back-up systems with roots in World War Two radio technology. Ships use GPS (Global Positioning System) and other similar devices that rely on sending and receiving satellite signals, which many experts say are vulnerable to jamming by hackers. About 90 percent of world trade is transported by sea and the stakes are high in increasingly crowded shipping lanes. Unlike aircraft, ships lack a back-up navigation system and if their GPS ceases to function, they risk running aground or colliding with other vessels. South Korea is developing an alternative system using an earth-based navigation technology known as eLoran, while the United States is planning to follow suit. Britain and Russia have also explored adopting versions of the technology, which works on radio signals. Cyber specialists say the problem with GPS and other Global Navigation Satellite Systems (GNSS) is their weak signals, which are transmitted from 12,500 miles above the Earth and can be disrupted with cheap jamming devices that are widely available. Developers of eLoran - the descendant of the loran (long-range navigation) system created during World War II - say it is difficult to jam as the average signal is an estimated 1.3 million times stronger than a GPS signal. To do so would require a powerful transmitter, large antenna and lots of power, which would be easy to detect, they add.

thomst writes: Slashdot stories have reported extensively on the LIGO experiments' initial detection of gravity waves emanating from collisions of primordial black holes, beginning, on February 11, 2016, with the first (and most widely-reported) such detection. Other Slashdot articles have chronicled the second LIGO detection event and the third one. There's even been a Slashdot report on the Synthetic Universe supercomputer model that provided support for the conclusion that the first detection event was, indeed, of a collision between two primordial black holes, rather than the more familiar stellar remnant kind that result from more recent supernovae of large-mass stars.
What interests me is the possibility that black holes of all kinds -- and particularly primordial black holes -- are so commonplace that they may be all that's required to explain the effects of "dark matter." Dark matter, which, according to current models, makes up some 26% of the mass of our Universe, has been firmly established as real, both by calculation of the gravity necessary to hold spiral galaxies like our own together, and by direct observation of gravitational lensing effects produced by the "empty" space between recently-collided galaxies. There's no question that it exists. What is unknown, at this point, is what exactly it consists of.
The leading candidate has, for decades, been something called WIMPs (Weakly-Interacting Massive Particles), a theoretical notion that there are atomic-scale particles that interact with "normal" baryonic matter only via gravity. The problem with WIMPs is that, thus far, not a single one has been detected, despite years of searching for evidence that they exist via multiple, multi-billion-dollar detectors.

Slashdot's awaiting-approval department:
An anonymous reader shares a report from The New York Times (Warning: source may be paywalled; alternative source): The average temperature in the United States has risen rapidly and drastically since 1980, and recent decades have been the warmest of the past 1,500 years, according to a sweeping federal climate change report awaiting approval by the Trump administration. The draft report by scientists from 13 federal agencies, which has not yet been made public, concludes that Americans are feeling the effects of climate change right now. It directly contradicts claims by President Trump and members of his cabinet who say that the human contribution to climate change is uncertain, and that the ability to predict the effects is limited. "Evidence for a changing climate abounds, from the top of the atmosphere to the depths of the oceans," a draft of the report states. A copy of it was obtained by The New York Times. The authors note that thousands of studies, conducted by tens of thousands of scientists, have documented climate changes on land and in the air. "Many lines of evidence demonstrate that human activities, especially emissions of greenhouse (heat-trapping) gases, are primarily responsible for recent observed climate change," they wrote. The report was completed this year and is a special science section of the National Climate Assessment, which is congressionally mandated every four years. The National Academy of Sciences has signed off on the draft report, and the authors are awaiting permission from the Trump administration to release it. "The report concludes that even if humans immediately stopped emitting greenhouse gases into the atmosphere, the world would still feel at least an additional 0.50 degrees Fahrenheit (0.30 degrees Celsius) of warming over this century compared with today," reports The New York Times. "The projected actual rise, scientists say, will be as much as 2 degrees Celsius." Given the Trump administration's stance on climate change, some of the scientists who worked on the report are concerned that the report will be suppressed.

Slashdot's come-together department:
tedlistens writes from a report via Fast Company: Robots are consistent, indefatigable workers, but they don't improvise well. Changes on the assembly line require painstaking reprogramming by humans, making it hard to switch up what a factory produces. Now researchers at German industrial giant Siemens say they have a solution: a factory that uses AI to orchestrate the factory of the future, by both programming factory robots and handing out assignments to the humans working alongside them. The program, called a "reasoner," figures out the steps required to make a product, such as a chair; then it divides the assignments among machines based their capabilities, like how far a robotic arm can reach or how much weight it can lift. The team has proved the technology can work on a small scale with a test system that uses just a few robots to make five types of furniture (like stools and tables), with four kinds of leg configurations, six color options, and three types of floor-protector pads, for a total of 360 possible products. Siemens's originally gave its automated factory project the badass Teutonic moniker "UberManufacturing." They weren't thinking of the German word connoting "superior," however, but rather of the on-demand car service. Part of their vision is that automated factories can generate bids for specialty, limited-run manufacturing projects and compete for customers in an online marketplace. "You could say, 'I want to build this stool,' and whoever has machines that can do that can hand in a quote, and that was our analogy to Uber," says Florian Michahelles, who heads the research group.

Slashdot's distribution-deals department:
Disney announced today that it will end its distribution deal with Netflix and launch its own streaming service in 2019. "The move is a real blow to Netflix, which secured a valuable streaming deal with Disney back in 2012 -- before streaming had really taken off," reports The Verge. "The deal only kicked into effect last year, so Netflix is barely seeing any benefit here." From the report: Netflix won't lose its Disney movies right away. Disney says it plans to cut Netflix off starting with the studio's 2019 films, and Netflix says it'll be able to keep all the Disney movies it gets through the end of that year. That means Netflix should be able to stream the next two Star Wars movies, but it'll miss out on the new trilogy's final installment. "We continue to do business with the Walt Disney Company on many fronts, including our ongoing deal with Marvel TV," said a spokesperson for Netflix. Disney's streaming service will be built off technology from BAMTech, the MLB-founded video streaming platform. Disney was already a major investor in BAMTech, and today it's making an even bigger investment -- of $1.58 billion -- giving it a 75 percent stake in the company. The acquisition still requires regulatory approval. The Disney-branded streaming service will be the "exclusive home in the U.S. for subscription-video-on-demand viewing," and will kick off with films including Toy Story 4 and the sequel to Frozen. "Original movies, TV shows, [and] short-form content" will be added to the service, and it'll be filled out with older movies from Disney and Pixar's catalog and shows from Disney's TV channels. The report also notes Disney plans to launch a streaming service exclusively for ESPN, targeted for launch early next year. "Disney is promising about '10,000 live regional, national, and international games and events a year,' with individual sports packages available as well," reports The Verge.

Slashdot's cut-ties department:
Soon, neither Internet Explorer nor Edge will recognize new security certificates from Chinese Certificate Authorities WoSign and its subsidiary StartCom. ZDNet reports: A CA is a trusted entity that issues X.509 digital certificates that verify a digital entity's identity on the internet. Certificates include its owner's public key and name, the certificate's expiration date, encryption method, and other information about the public key owner. Typically, these are used to secure websites with the https protocol, lock down internet communications with Secure Sockets Layer and Transport Layer Security (SSL/TLS), and secure virtual private networks (VPNs). A corrupted certificate is barely better than no protection at all. It can be used to easily hack websites and "private" internet communications. Microsoft has joined [Mozilla, Google and Apple] in abandoning trust in their certificates. A Microsoft representative wrote: "Microsoft has concluded that the Chinese CAs WoSign and StartCom have failed to maintain the standards required by our Trusted Root Program. Observed unacceptable security practices include back-dating SHA-1 certificates, mis-issuances of certificates, accidental certificate revocation, duplicate certificate serial numbers, and multiple CAB Forum Baseline Requirements (BR) [issuance and management rules for public certificates] violations." Microsoft will start "the natural deprecation of WoSign and StartCom certificates by setting a 'NotBefore' date of 26 September 2017. This means all existing certificates will continue to function until they self-expire. Windows 10 will not trust any new certificates from these CAs after September 2017."

Slashdot's regretful-thinking department:
New submitter cdreimer writes: According to a report in The Wall Street Journal (Warning: source may be paywalled, alternative source), the author behind the U.S. government's password requirements regrets wasting our time on changing passwords so often. From the report: "The man who wrote the book on password management has a confession to make: He blew it. Back in 2003, as a midlevel manager at the National Institute of Standards and Technology, Bill Burr was the author of 'NIST Special Publication 800-63. Appendix A.' The 8-page primer advised people to protect their accounts by inventing awkward new words rife with obscure characters, capital letters and numbers -- and to change them regularly. The document became a sort of Hammurabi Code of passwords, the go-to guide for federal agencies, universities and large companies looking for a set of password-setting rules to follow. The problem is the advice ended up largely incorrect, Mr. Burr says. Change your password every 90 days? Most people make minor changes that are easy to guess, he laments. Changing Pa55word!1 to Pa55word!2 doesn't keep the hackers at bay. Also off the mark: demanding a letter, number, uppercase letter and special character such as an exclamation point or question mark -- a finger-twisting requirement." "Much of what I did I now regret," Bill Burr told The Wall Street Journal. "In the end, [the list of guidelines] was probably too complicated for a lot of folks to understand very well, and the truth is, it was barking up the wrong tree."

Slashdot's next-billion-users department:
An anonymous reader shares a WSJ article: The internet's global expansion is entering a new phase, and it looks decidedly unlike the last one. Instead of typing searches and emails, a wave of newcomers -- "the next billion," the tech industry calls them -- is avoiding text, using voice activation and communicating with images. They are a swath of the world's less-educated, online for the first time thanks to low-end smartphones, cheap data plans and intuitive apps that let them navigate despite poor literacy. Incumbent tech companies are finding they must rethink their products for these newcomers and face local competitors that have been quicker to figure them out. "We are seeing a new kind of internet user," said Ceasar Sengupta, who heads a group at Alphabet's Google trying to adapt to the new wave. "The new users are very different from the first billion." A look at Megh Singh's smartphone suggests how the next billion might determine a new set of winners and losers in tech. Mr. Singh, 36, balances suitcases on his head in New Delhi, earning less than $8 a day as a porter in one of India's biggest railway stations. He isn't comfortable reading or using a keyboard. That doesn't stop him from checking train schedules, messaging family and downloading movies. "We don't know anything about emails or even how to send one," said Mr. Singh, who went online only in the past year. "But we are enjoying the internet to the fullest." Mr. Singh squatted under the station stairwell, whispering into his phone using speech recognition on the station's free Wi-Fi. It is a simple affair, a Sony Corp. model with 4GB of storage, versus the 32GB that is typically considered minimal in the developed world. On his screen are some of the world's most popular apps -- Google's search, Facebook's WhatsApp -- but also many that are unfamiliar in the developed world, including UC Browser, MX Player and SHAREit, that have been tailored for slow connections and skimpy data storage.

An anonymous reader writes: Several Internet service providers in India have blocked access to Internet Archive -- a non-profit organisation that runs Wayback Machine, a massive archive of webpages dating back to over a decade -- Indian outlet NDTV reported Tuesday. Some subscribers of Airtel, Aircel, and Act Internet, among other carriers, are seeing a DoT notification when they attempt to access Internet Archive. The notification reads, 'Your requested URL has been blocked as per the directions received from Department of Telecommunications, Government of India.' Popularly known as time-warping tool, Internet Archive's Way Back Machine has made copies of over three billion pages over the years. In the age of ephemeral media, Way Back Machine has become a cultural phenomenon, serving as a permanent registrar of popular websites and other webpages.
