Bitcoin Gold, the Latest Bitcoin Fork, Explained
Timothy B. Lee via Ars Technica explains Bitcoin Gold:
A new cryptocurrency called Bitcoin Gold is now live on the Internet. It aims to correct what its backers see as a serious flaw in the design of the original Bitcoin. There are hundreds of cryptocurrencies on the Internet, and many of them are derived from Bitcoin in one way or another. But Bitcoin Gold -- like Bitcoin Cash, another Bitcoin spinoff that was created in August -- is different in two important ways. Bitcoin Gold is branding itself as a version of Bitcoin rather than merely new platforms derived from Bitcoin's source code. It has also chosen to retain Bitcoin's transaction history, which means that, if you owned bitcoins before the fork, you now own an equal amount of "gold" bitcoins. While Bitcoin Cash was designed to resolve Bitcoin's capacity crunch with larger blocks, Bitcoin Gold aims to tackle another of Bitcoin's perceived flaws: the increasing centralization of the mining industry that verifies and secures Bitcoin transactions.
The original vision for Bitcoin was that anyone would be able to participate in Bitcoin mining with their personal PCs, earning a bit of extra cash as they helped to support the network. But as Bitcoin became more valuable, people discovered that Bitcoin mining could be done much more efficiently with custom-built application-specific integrated circuits (ASICs). As a result, Bitcoin mining became a specialized and highly concentrated industry. The leading companies in this new industry wield a disproportionate amount of power over the Bitcoin network. Bitcoin Gold aims to dethrone these mining companies by introducing an alternative mining algorithm that's much less susceptible to ASIC-based optimization. In theory, that will allow ordinary Bitcoin Gold users to earn extra cash with their spare computing cycles, just as people could do in the early days of Bitcoin.
Uber Drivers In Lagos Are Using a Fake GPS App To Inflate Rider Fares
According to Quartz, some Uber drivers in Lagos have been
using a fake GPS itinerary app called Lockito to illicitly bump up fares for local drivers. The
app was initially created for developers to "test geofencing-based apps," but has been used by Uber drivers to inflate the cost of their trips. From the report:
In some cases, inflated trips can cost riders more than double the rate they should be paying. "It's more like a parasite," says Mohammed, a driver for both Uber and Taxify in Lagos. "It sets the false GPS movement while allowing the phone also to keep track of its actual movement. The Uber app can't tell the difference between both so it just calculates both." When a driver uses Lockito for an Uber trip he or she can have the fake GPS running (and calculating a fake fare) from the pickup point to the drop off location, before the passenger has even got into the car. When the real trip starts, the real GPS starts running and calculating the actual fare. But at the end of the journey the fares from both trips (real and fake) are tallied up as one fare which the unsuspecting rider pays. Some drivers use Lockito to inflate fares by adding 1000 naira to 2000 naira extra (roughly $3 to $6) but some drivers are believed to inflate fares to exorbitant levels.
Ask Slashdot: Which Software/Devices Are Unusable Without Connecting to the Internet?
Currently, most commercial software and hardware manufactures rely on an internet connection for registering or activating their products and providing additional functionality. In an ideal world this works fine, but in our real world the buyer could lose access to internet for months -- such as in emergency situations like the aftermath of hurricane Maria -- and their products will refuse to work because they need an internet connection. Which companies are using their internet servers as replacements for hardware dongles? I want to see a complete list of software and devices that become completely unusable without a live internet connection. Just remember the infamous case of the Razer Synapse.
China Overtakes US In Latest Top 500 Supercomputer List
An anonymous reader quotes a report from Enterprise Cloud News:
The release of the semiannual Top 500 Supercomputer List is a chance to gauge the who's who of countries that are pushing the boundaries of high-performance computing. The most recent list, released Monday, shows that China is now in a class by itself. China now claims 202 systems within the Top 500, while the United States -- once the dominant player -- tumbles to second place with 143 systems represented on the list. Only a few months ago, the U.S. had 169 systems within the Top 500 compared to China's 160. The growth of China and the decline of the United States within the Top 500 has prompted the U.S. Department of Energy to doll out $258 million in grants to several tech companies to develop exascale systems, the next great leap in HPC. These systems can handle a billion billion calculations a second, or 1 exaflop. However, even as these physical machines grow more and more powerful, a good portion of supercomputing power is moving to the cloud, where it can be accessed by more researchers and scientists, making the technology more democratic.
Google To Kill a Bunch of Useful Android Apps That Rely On Accessibility Services
Lauren Weinstein writes from a blog:
My inbox has been filling today with questions regarding Google's new warning to Android application developers that they will no longer be able to access Android accessibility service functions in their apps, unless they can demonstrate that those functions are specifically being used to help users with "disabilities" (a term not defined by Google in the warning). Beyond the overall vagueness when it comes to what is meant by disabilities, this entire approach by Google seems utterly wrongheaded and misguided. "While the intended purpose is for developers to create apps for users with disabilities, the API is often used for other functionality (to overlay content, fill in text fields, etc.),"
reports Android Police. "LastPass, Universal Copy, Clipboard Actions, Cerberus, Signal Spy, Tasker, and Network Monitor Mini are just a few examples of applications heavily using this API." It's likely Google is cracking down on apps that use Accessibility Services due to the security risks they pose. "Once granted the right permissions, the API can be used to read data from other apps," reports Android Police.
Solar Companies Are Scrambling to Find a Critical Raw Material
Solar manufacturers are being battered by higher costs and smaller margins, after an unexpected shortage of a critical raw material. From a report, shared by an anonymous reader:
Prices of polysilicon, the main component of photovoltaic cells, spiked as much as 35 percent in the past four months after environmental regulators in China shut down several factories. That's driving up production costs as panel prices continue to decline, and dragging down earnings for manufacturers in China, the world's biggest supplier. "There's just not enough polysilicon in China," said Carter Driscoll, an analyst who covers solar companies for FBR & Co. "If prices don't come down, it will crush margins."
Amazon Is Making a 'Lord of the Rings' Prequel Series
making a Lord of the Rings prequel TV series for its Amazon Instant streaming service. The show, which already
carries a multi-season commitment, will "explore new storylines preceding J.R.R. Tolkien's
The Fellowship of the Ring." TechCrunch reports:
It's possible the new series will mine the ponderous but rich Silmarillion for material, as fan fiction writers and lore aficionados have done for decades. The exploits of the Elf-Lords of old would make for a stirring epic, while many would thrill at the possibility of seeing Moria at the height of its grandeur. So much depends on the quality of the adaptation, though. Amazon has been pretty good about its Originals, but this will be an undertaking far beyond the scope of anything its studios and partners have yet attempted. Amazon is partnering with New Line Cinema, which of course was the film company behind the much-loved trilogy that began in 2001, and the Tolkien Estate, as well as HarperCollins for some reason. The deal also "includes a potential additional spin-off series," presumably if it's popular enough.
More Than 15,000 Scientists From 184 Countries Issue 'Warning To Humanity'
An anonymous reader quotes a report from CBC.ca:
More than 15,000 scientists around the world have issued a global warning: there needs to be change in order to save Earth. It comes 25 years after the first notice in 1992 when a mere 1,500 scientists issued a similar warning. This new cautioning -- which gained popularity on Twitter with #ScientistsWarningToHumanity -- garnered more than 15,000 signatures. William Ripple of Oregon State University's College of Forestry, who started the campaign, said that he came across the 1992 warning last February, and noticed that this year happened to mark the 25th anniversary. Together with his graduate student, Christopher Wolf, he decided to revisit the concerns raised then, and collect global data for different variables to show trends over the past 25 years. Ripple found: A decline in freshwater availability; Unsustainable marine fisheries; Ocean dead zones; Forest losses; Dwindling biodiversity; Climate change; Population growth. There was one positive outcome, however: a rapid decline in ozone depletion. One of the potential solutions is to stabilize the population. If we reduce family size, consumption patterns don't rise as much. And that can be done by empowering girls and women, providing sexual education and education on family planning.
Google Subpoenaed Over Data Privacy, Antitrust in Missouri
Google is facing a new front in its regulatory battles after Missouri's attorney general on Monday launched a broad investigation into
whether the company's business practices violate the state's consumer-protection and antitrust laws. From a report:
Attorney General Josh Hawley's office said on Monday that it issued a subpoena to investigate if Google's use of information that it collects about consumers is appropriate and if the company stifles competing websites in search results. Google has largely steered clear of antitrust problems in the U.S. That's not the case in Europe, where the company faces a fine of about $2.7 billion over the display of its shopping ads.
Firefox 57 Brings Better Sandboxing on Linux
Catalin Cimpanu, writing for BleepingComputer:
Firefox 57, set to be released tomorrow, will ship with improvements to the browser's sandbox security feature for Linux users. The Firefox sandboxing feature isolates the browser from the operating system in a way to prevent web attacks from using a vulnerability in the browser engine and its legitimate functions to attack the underlying operating system, place malware on the filesystem, or steal local files. Chrome has always run inside a sandbox. Initially, Firefox ran only a few plugins inside a sandbox -- such as Flash, DRM, and other multimedia encoding plugins.
Not Every Article Needs a Picture
An anonymous reader shares an article:
Pictures and text often pair nicely together. You have an article about a thing, and the picture illustrates that thing, which in many cases helps you understand the thing better. But on the web, this logic no longer holds, because at some point it was decided that all texts demand a picture. It may be of a tangentially related celeb. It may be a stock photo of a person making a face. It may be a Sony logo, which is just the word SONY. I have been thinking about this for a long time and I think it is stupid. I understand that images -- clicks is industry gospel, but it seems like many publishers have forgotten their sense of pride. If a picture is worth a thousand words, it's hard for me to imagine there'll be much value in the text of an article illustrated by a generic stock image. As with so many problems, social media seems to deserve much of the blame for this. Until the mid-to-late '00s, a publication's homepage played a dominant role in driving people to individual articles. Homepages mostly mimicked the front pages of newspapers, where major stories -- things that warranted investment in original art -- had images. Other stories just got a headline. Over time, the endless space of the internet lowered the standard for which articles needed art, but still, not everything got an image. [...] Even the unflinching belief that people won't read articles if there aren't pictures doesn't hold up to logic. Sure, interesting pictures can attract readers, but most of these images are not interesting. And even if it were slightly better for business, is that really a compromise worth making?
Verizon, AT&T Announce Plans To Build and Share Hundreds of New Cell Towers
An anonymous reader shares a report:
Verizon and AT&T announced a joint venture with Tillman Infrastructure to build and share hundreds of cell towers in more in a move that is sure to be seen as a threat to more established tower companies. The companies said the new structures "will add to the overall communications infrastructure in the United States," filling gaps in current tower footprints, but will also enable the nation's two largest network operators to relocate equipment from towers they're currently using. Construction plans on the first towers will begin early next year and will come online "quickly" as they are completed.
Payphones Still Make Millions of Dollars
From a report on Motherboard:
Disruption-y tech companies like Uber and Twitter are a big part of "the discourse" and our daily lives, but neither of them make any profit. You know what once-groundbreaking technology doesn't have any problems making bank year after year? That's right, it's payphones. Most people now have a cell phone, so you may have wondered who still uses those rusted, quarter-eating boxes. As it turns out, a lot of people do. According to the Canadian Radio-television and Telecommunications Commission's 2017 monitoring report, payphones in Canada made $22 million CAD in 2016 (this figure may not account for the cost of upkeep, but the CRTC has stated in the past that payphones are "financially viable at current rates.") That's spread out among nearly 60,000 payphones in the country, which made roughly $300 per phone over the course of the year. That's at least a few calls per day, each. The US numbers are similar: The FCC reports that in 2015 payphones made $286 million, which is comparable for a population ten times the size of Canada's.
Munich Council: To Hell With Linux, We're Going Full Windows in 2020
The German city of Munich, which received much popularity back in the day when it first ditched Microsoft's services in favor of open-source software, has
now agreed to stop using Linux and switch back to Windows. If the decision is ratified by the full council in two weeks, Windows 10 will start rolling out across the city in 2020. From a report:
A coalition of Social Democrats and Conservatives on the committee voted for the Windows migration last week, Social Democrat councillor Anne Hubner told The Register. Munich rose to fame in the open-source world for deciding to use Linux and LibreOffice to make the city independent from the claws of Microsoft. But the plan was never fully realised -- mail servers, for instance, eventually wound up migrating to Microsoft Exchange -- and in February the city council formally voted to end Linux migration and go back to Microsoft. Hubner said the city has struggled with LiMux adoption. "Users were unhappy and software essential for the public sector is mostly only available for Windows," she said. She estimated about half of the 800 or so total programs needed don't run on Linux and "many others need a lot of effort and workarounds." Hubner added, "in the past 15 years, much of our efforts were put into becoming independent from Microsoft," including spending "a lot of money looking for workarounds" but "those efforts eventually failed." A full council vote on Windows 10 2020 migration is set for November 23, Hubner said. However, the Social Democrats and Conservatives have a majority in the council, and the outcome is expected to be the same as in committee.
Huddle's 'Highly Secure' Work Tool Exposed KPMG And BBC Files
Chris Foxx, reporting for BBC:
The BBC has discovered a security flaw in the office collaboration tool Huddle that led to private documents being exposed to unauthorised parties. A BBC journalist was inadvertently signed in to a KPMG account, with full access to private financial documents. Huddle is an online tool that lets work colleagues share content and describes itself as "the global leader in secure content collaboration." The company said it had fixed the flaw. Its software is used by the Home Office, Cabinet Office, Revenue & Customs, and several branches of the NHS to share documents, diaries and messages. "If somebody is putting themselves out there as a world-class service to look after information for you, it just shouldn't happen," said Prof Alan Woodward, from the University of Surrey. "Huddles contain some very sensitive information."
Amazon Developing a Free, Ad-Supported Version of Prime Video: Report
Amazon is developing a free, ad-supported complement to its Prime streaming video service, AdAge reported on Monday, citing people familiar with Amazon's plans. From the report:
The company is talking with TV networks, movie studios and other media companies about providing programming to the service, they say. Amazon Prime subscribers pay $99 per year for free shipping but also access to a mix of ad-free TV shows, movies and original series such as "Transparent" and "The Man in the High Castle." It has dabbled in commercials on Prime to a very limited degree, putting ads inside National Football League games this season and offering smaller opportunities for brand integrations. A version paid for by advertisers instead of subscribers could provide a new foothold in streaming video for marketers, whose opportunities to run commercials are eroding as audiences drift away from traditional TV and toward ad-free services like Netflix and Prime.
Bill Gates Pledges $100 Million To Find an Alzheimer's Cure, His First Commitment To a Non-communicable Disease
At present, there is no treatment to stop the Alzheimer's. Bill Gates wants to make a sizeable attempt to change that. From a report:
He is to invest $50 million in the Dementia Discovery Fund, a venture capital fund that brings together industry and government to seek treatments for the brain-wasting disease. The investment -- a personal one and not part of Gates' philanthropic Bill & Melinda Gates Foundation -- will be followed by another $50 million in start-up ventures working in Alzheimer's research, Gates said. "It's a huge problem, a growing problem, and the scale of the tragedy -- even for the people who stay alive -- is very high," he said. Despite decades of scientific research, there is no treatment that can slow the progression of Alzheimer's. Current drugs can do no more than ease some of the symptoms.
Qualcomm Board of Directors Unanimously Rejects Broadcom's Unsolicited Proposal
U.S. chipmaker Qualcomm on Monday rejected rival
Broadcom's $103 billion bid to purchase the company, stating that Broadcom's proposal
"dramatically undervalues" Qualcomm and comes with "significant regulatory uncertainty.".
Hackers Say They've Broken Face ID a Week After iPhone X Release
Andy Greenberg, writing for Wired:
When Apple released the iPhone X on November 3, it touched off an immediate race among hackers around the world to be the first to fool the company's futuristic new form of authentication. On Friday, Vietnamese security firm Bkav released a blog post and video showing that -- by all appearances -- they'd cracked Face ID with a composite mask of 3-D-printed plastic, silicone, makeup, and simple paper cutouts, which in combination tricked an iPhone X into unlocking. That demonstration, which has yet to be confirmed publicly by other security researchers, could poke a hole in the expensive security of the iPhone X, particularly given that the researchers say their mask cost just $150 to make. But it's also a hacking proof-of-concept that, for now, shouldn't alarm the average iPhone owner, given the time, effort, and access to someone's face required to recreate it. Bkav, meanwhile, didn't mince words in its blog post and FAQ on the research. "Apple has done this not so well," writes the company. "Face ID can be fooled by mask, which means it is not an effective security measure."
New Study Suggests We Don't Understand Supervolcanoes
Better microsampling (and analysis) are revealing "previously obscured" clues about how super-hot molten lava behaves, according to a Science Alert article shared by
"The older view is that there's a long period with a big tank of molten rock in the crust," says geoscientist Nathan Andersen from the University of Wisconsin-Madison. "A new view is that magma is stored for a long period in a state that is locked, cool, crystalline, and unable to produce an eruption. That dormant system would need a huge infusion of heat to erupt." Such a huge infusion of heat is what's thought to have unleashed a violent supereruption in California some 765,000 years ago... [A]s awesomely destructive as the supereruption was, lingering evidence from the aftermath can tell us about the magma conditions deep underground before the top blew so spectacularly.
Specifically, an analysis of argon isotopes contained in crystals from the Bishop Tuff -- the large rocky outcrop produced when the Long Valley Caldera was created -- shows the magma from the supereruption was heated rapidly, not slowly simmered. Geologically speaking, that is -- meaning the heating forces that produced the supereruption occurred over decades, or perhaps a couple of centuries. (A long time for people, sure, but a blink of an eye in the life-time of a supervolcano.) The reasoning is that argon quickly escapes from hot crystals, so it wouldn't have a chance to accumulate in the rock if the rock were super-heated for a long time... Unfortunately, while scientists are doing everything they can to read the signs of volcanic supereruptions -- something NASA views as more dangerous than asteroid strikes -- the reality is, the new findings don't bring us any closer to seeing the future.
"This does not point to prediction in any concrete way," warns geologist Brad Singer, "but it does point to the fact that
we don't understand what is going on in these systems, in the period of 10 to 1,000 years that precedes a large eruption."
Asgardia Becomes the First Nation Deployed in Space
An anonymous reader quotes CNET:
An Orbital ATK Antares rocket carrying a cubesat named Asgardia-1 launched from NASA's Wallops Flight Facility in Virginia early Sunday. The milk carton-sized satellite makes up the entirety of territory of the self-proclaimed "Space Kingdom" of Asgardia... Over 300,000 people signed up online to become "citizens" of the nation over the last year. The main privilege of citizenship so far involves the right to upload data to Asgardia-1 for safekeeping in orbit, seemingly far away from the pesky governments and laws of Earth-bound countries...
As of now, Asgardia's statehood isn't acknowledged by any other actual countries or the United Nations, and it doesn't really even fit the definition of a nation since it's not possible for a human to physically live in Asgardia. Not yet, at least. The long-term vision for Asgardia includes human settlements in space, on the moon and perhaps even more distant colonies.
On Tuesday Orbital ATK's spacecraft will dock with the International Space Station for a one-month re-supply mission -- then blast higher into orbit to deploy the space kingdom's satellite. "Asgardia space kingdom has now
established its sovereign territory in space," read an online statement.
Next the space kingdom plans to
hold elections for 150 Members of Parliament.
Ask Slashdot: Which Laptop Has The Best Keyboard?
Rock21k is thinking of replacing an old laptop. But...
All newer laptops seem to have wide spacing between the keyboard keys, which I hate... At one time, this used to be for consumer laptops but most major companies have done it for business laptops as well... Probably over time I might get used to it, but definitely not the first choice. I understand I can use an external keyboard but that defeats the purpose of a laptop! Do you also hate wide spacing between keyboard keys? Which brand do you find least annoying? Leave your best answers in the comments. Which laptop has the best keyboard?
