Long-time Slashdot reader Yhcrana shares "some good old fashioned astronomy news." Astronomers have discovered "a black hole 20 billion times the mass of the sun eating the equivalent of a star every two days," reports the New York Times.
The black hole is growing so rapidly, said Christian Wolf, of the Australian National University, who led the team that found it in the depths of time, "that it is probably 10,000 times brighter than the galaxy it lives in." So bright, that it is dazzling our view and we can't see the galaxy itself. He and his colleagues announced the discovery in a paper to be published in the Publications of the Astronomical Society of Australia...
The blaze from material swirling around this newly observed drainpipe into eternity -- known officially as SMSS J215728.21-360215.1 -- is as luminous as 700 trillion suns, according to Wolf and his collaborators. If it were at the center of our own galaxy, the Milky Way, it would be 10 times brighter than the moon and bathe the Earth in so many X-rays that life would be impossible. Luckily it's not anywhere nearby. It is in fact 12 billion light years away, which means it took that long for its light to reach us, so we are glimpsing this cataclysm as it appeared at the dawn of time, only 2 billion years after the Big Bang, when stars and galaxies were furiously forming.Read Replies (0)

"You could look at this as a smallish PDP-11/70, built with modern parts," Oscar Vermeulen writes on his site. "Or alternatively, and equally valid, as a fancy front panel case for a Raspberry Pi."
Long-time Slashdot reader cptnapalm writes: Oscar Vermeulen's PiDP-11 front panel, modeling a PDP-11/70 in all its colorful glory, has been released to beta testers. This is Mr. Vermeulen's second DEC front panel; his PiDP-8 was released a few years ago. The PiDP-11 panel is designed to work with a Raspberry Pi running simh or, possibly, a FPGA implementation of the Digital Equipment Corporation PDP-11... In addition to the front panel with its switches and blinkenlights, also included is a prototyping area for the possibility of adding new hardware...
UNIX and later BSD were developed on the PDP-11, including both the creation of the C language, the pipe concept and the text editor vi.Read Replies (0)

"I asked Apple to give me all the data it's collected on me since I first became a customer in 2010," writes the security editor for ZDNet, "with the purchase of my first iPhone."
That was nearly a decade ago. As most tech companies have grown in size, they began collecting more and more data on users and customers -- even on non-users and non-customers... Apple took a little over a week to send me all the data it's collected on me, amounting to almost two dozen Excel spreadsheets at just 5MB in total -- roughly the equivalent of a high-quality photo snapped on my iPhone. Facebook, Google, and Twitter all took a few minutes to an hour to send me all the data they store on me -- ranging from a few hundred megabytes to a couple of gigabytes in size...
The zip file contained mostly Excel spreadsheets, packed with information that Apple stores about me. None of the files contained content information -- like text messages and photos -- but they do contain metadata, like when and who I messaged or called on FaceTime. Apple says that any data information it collects on you is yours to have if you want it, but as of yet, it doesn't turn over your content which is largely stored on your slew of Apple devices. That's set to change later this year... And, of the data it collects to power Siri, Maps, and News, it does so anonymously -- Apple can't attribute that data to the device owner... One spreadsheet -- handily -- contained explanations for all the data fields, which we've uploaded here...
[T]here's really not much to it. As insightful as it was, Apple's treasure trove of my personal data is a drop in the ocean to what social networks or search giants have on me, because Apple is primarily a hardware maker and not ad-driven, like Facebook and Google, which use your data to pitch you ads.

"Researchers may have identified a compound that can stop some of the most common cold viruses, the rhinovirus, in its tracks, according to a new report published in the journal Nature." An anonymous reader quotes Fortune:
The scientists' work is early-stage. But the mechanism it uses to tackle colds is striking. Developed at the Imperial College London, the molecule targets a protein in human cells that cold viruses use in order to replicate and conquer. By targeting this specific pathway, the compound could theoretically be used to thwart most viruses (and since it focuses on human proteins, it may not cause the virus to mutate its way away from danger)...
"The common cold is an inconvenience for most of us, but can cause serious complications in people with conditions like asthma and [chronic lung disease]," said lead researcher Ed Tate in a statement. "A drug like this could be extremely beneficial if given early in infection, and we are working on making a version that could be inhaled, so that it gets to the lungs quickly."Read Replies (0)

The Amazon Echo and other smart speakers have helped push the audience for digital radio past that of FM and AM in the UK for the first time. According to Radio Joint Audience Research (RAJAR), digital listening has reached a new record share of 50.9%, up from 47.2% a year ago. This milestone will trigger a government review into whether the analog FM radio signal should be switched off altogether. iNews reports: The BBC said it would be "premature" to switch off the FM signal. It could cut off drivers with analogue car radios and disenfranchise older wireless listeners. Margot James, Digital minister, welcomed "an important milestone for radio." She confirmed that the Government will "work closely with all partners -- the BBC, commercial radio, (transmitter business) Arqiva, car manufacturers and listeners" before committing to a timetable for analogue switch-off.
James Purnell, BBC Director of Radio and Education, said: "We're fully committed to digital, and growing its audiences, but, along with other broadcasters, we've already said that it would be premature to switch off FM." Mr Purnell said that BBC podcast listening was up a third across all audiences since the same time last year, accounting now for 40,000 hours a week. But younger audiences have not inherited the habit of listening to "live" radio, even on digital.Read Replies (0)

The FCC has opened an investigation into LocationSmart, a company that is buying your real-time location data from four of the largest U.S. carriers in the United States. The investigation comes a day after a security researcher from Carnegie Mellon University exposed a vulnerability on LocationSmart's website. CNET reports: The bug has prompted an investigation from the FCC, the agency said on Friday. An FCC spokesman said LocationSmart's case was being handled by its Enforcement Bureau. Since The New York Times revealed that Securus, an inmate call tracking service, had offered the same tracking service last week, Sen. Ron Wyden, a Democrat from Oregon, called for the FCC and major wireless carriers to investigate these companies. On Friday, Wyden praised the investigation, but requested the FCC to expand its look beyond LocationSmart.
"The negligent attitude toward Americans' security and privacy by wireless carriers and intermediaries puts every American at risk," Wyden said. "I urge the FCC expand the scope of this investigation, and to more broadly probe the practice of third parties buying real-time location data on Americans." He is also calling for FCC Chairman Ajit Pai to recuse himself from the investigation, because Pai was a former attorney for Securus.Read Replies (0)

An anonymous reader quotes a report from The New York Times: Will it soon be possible to simulate the feeling of a spirit not attached to any particular physical form using virtual or augmented reality? If so, a good place to start would be to figure out the minimal amount of body we need to feel a sense of self, especially in digital environments where more and more people may find themselves for work or play. It might be as little as a pair of hands and feet, report Dr. Michiteru Kitazaki and a Ph.D. student, Ryota Kondo. In a paper published Tuesday in Scientific Reports, they showed that animating virtual hands and feet alone is enough to make people feel their sense of body drift toward an invisible avatar (Warning: source may be paywalled; alternative source). Their work fits into a corpus of research on illusory body ownership, which has challenged understandings of perception and contributed to therapies like treating pain for amputees who experience phantom limb.
Using an Oculus Rift virtual reality headset and a motion sensor, Dr. Kitazaki's team performed a series of experiments in which volunteers watched disembodied hands and feet move two meters in front of them in a virtual room. In one experiment, when the hands and feet mirrored the participants' own movements, people reported feeling as if the space between the appendages were their own bodies. In another experiment, the scientists induced illusory ownership of an invisible body, then blacked out the headset display, effectively blindfolding the subjects. The researchers then pulled them a random distance back and asked them to return to their original position, still virtually blindfolded. Consistently, the participants overshot their starting point, suggesting that their sense of body had drifted or "projected" forward, toward the transparent avatar.Read Replies (0)

Yuriy Bulygin, the former head of Intel's advanced threat team, has published research showing that the Spectre CPU flaws can be used to break into the highly privileged CPU mode on Intel x86 systems known as System Management Mode (SMM). ZDNet reports: Bulygin, who has launched security firm Eclypsium, has modified Spectre variant 1 with kernel privileges to attack a host system's firmware and expose code in SMM, a secure portion of BIOS or UEFI firmware. SMM resides in SMRAM, a protected region of physical memory that should only be accessible by BIOS firmware and not the operating system kernel, hypervisors or security software. SMM handles especially disruptive interrupts and is accessible through the SMM runtime of the firmware, knows as System Management Interrupt (SMI) handlers.
"Because SMM generally has privileged access to physical memory, including memory isolated from operating systems, our research demonstrates that Spectre-based attacks can reveal other secrets in memory (eg, hypervisor, operating system, or application)," Bulygin explains. To expose code in SMM, Bulygin modified a publicly available proof-of-concept Spectre 1 exploit running with kernel-level privileges to bypass Intel's System Management Range Register (SMRR), a set or range registers that protect SMM memory. "These enhanced Spectre attacks allow an unprivileged attacker to read the contents of memory, including memory that should be protected by the range registers, such as SMM memory," he notes.Read Replies (0)

According to security company McAfee, North Korea uploaded three spying apps to the Google Play Store in January that contained hidden functions designed to steal personal photos, contact lists, text messages, and device information from the phones they were installed on. "Two of the apps purported to be security utilities, while a third provided information about food ingredients," reports The Inquirer. All three of the apps were part of a campaign dubbed "RedDawn" and targeted primarily North Korean defectors. From the report: The apps were promoted to particular targets via Facebook, McAfee claims. However, it adds that the malware was not the work of the well-known Lazarus Group, but another North Korean hacking outfit that has been dubbed Sun Team. The apps were called Food Ingredients Info, Fast AppLock and AppLockFree. "Food Ingredients Info and Fast AppLock secretly steal device information and receive commands and additional executable (.dex) files from a cloud control server. We believe that these apps are multi-staged, with several components."

"Because it apparently isn't bad enough already, Congress is looking to extend the copyright term to 144 years," writes Slashdot reader llamalad. "Please write to your representatives and consider donating to the EFF." American attorney Lawrence Lessig writes via Wired: Almost exactly 20 years ago, Congress passed the Sonny Bono Copyright Term Extension Act, which extended the term of existing copyrights by 20 years. The Act was the 11th extension in the prior 40 years, timed perfectly to assure that certain famous works, including Mickey Mouse, would not pass into the public domain. Immediately after the law came into force, a digital publisher of public domain works, Eric Eldred, filed a lawsuit challenging the act [which the Supreme Court later rejected].
Twenty years later, the fight for term extension has begun anew. Buried in an otherwise harmless act, passed by the House and now being considered in the Senate, this new bill purports to create a new digital performance right -- basically the right to control copies of recordings on any digital platform (ever hear of the internet?) -- for musical recordings made before 1972. These recordings would now have a new right, protected until 2067, which, for some, means a total term of protection of 144 years. The beneficiaries of this monopoly need do nothing to get the benefit of this gift. They don't have to make the work available. Nor do they have to register their claims in advance.Read Replies (0)

The current data-crunching approach to machine learning misses an essential element of human intelligence. From a report: Amid rapid developments and nagging setbacks, one essential building block of human intelligence has eluded machines for decades: Understanding cause and effect. Put simply, today's machine-learning programs can't tell whether a crowing rooster makes the sun rise, or the other way around. Whatever volumes of data a machine analyzes, it cannot understand what a human gets intuitively. From the time we are infants, we organize our experiences into causes and effects. The questions "Why did this happen?" and "What if I had acted differently?" are at the core of the cognitive advances that made us human, and so far are missing from machines. Suppose, for example, that a drugstore decides to entrust its pricing to a machine learning program that we'll call Charlie. The program reviews the store's records and sees that past variations of the price of toothpaste haven't correlated with changes in sales volume. So Charlie recommends raising the price to generate more revenue. A month later, the sales of toothpaste have dropped -- along with dental floss, cookies and other items. Where did Charlie go wrong? Charlie didn't understand that the previous (human) manager varied prices only when the competition did. When Charlie unilaterally raised the price, dentally price-conscious customers took their business elsewhere. The example shows that historical data alone tells us nothing about causes -- and that the direction of causation is crucial.Read Replies (0)

Google is reportedly working on a standalone augmented reality headset that will use new Qualcomm chips. "It will be built by Taiwanese computer maker Quanta," reports The Verge. "The project is still in its early stages, according to documents obtained by WinFuture." From the report: The AR headset is supposed to be similar to Microsoft's HoloLens, a headset that came out in 2016 and is aimed at design, training, and industrial use. The Google AR headset that's in development will reportedly be self-contained and powered by a Qualcomm chip, rather than tethered to another device. It will also include cameras and microphones. The headset is currently going by the name "Google A65." There's no release date yet for the Google A65 as it's still in the prototype stage, according to WinFuture. The headset won't only operate like a HoloLens, but it will use the same chips. HoloLens is rumored to be getting an update this year, with a new ARM-powered design and an improved field of view. The Qualcomm chips that will reportedly be used in both the new HoloLens and the new Google headset are the Qualcomm QSC603 four-core chips, based on ARM architecture.Read Replies (0)

President Trump personally urged the leader of the U.S. Postal Service to double the rates the agency charges Amazon and other firms for delivery packages in several private conversations in 2017 and 2018, The Washington Post reported Friday (alternative source). From the report: Postmaster General Megan Brennan has so far resisted Trump's demand, explaining in multiple conversations occurring this year and last that these arrangements are bound by contracts and must be reviewed by a regulatory commission, the three people said. She has told the president that the Amazon relationship is beneficial for the Postal Service and gave him a set of slides that showed the variety of companies, in addition to Amazon, that also partner for deliveries. Despite these presentations, Trump has continued to level criticism at Amazon. And last month, his critiques culminated in the signing of an executive order mandating a government review of the financially strapped Postal Service that could lead to major changes in the way it charges Amazon and others for package delivery. Few U.S. companies have drawn Trump's ire as much as Amazon, which has rapidly grown to be the second-largest U.S. company in terms of market capitalization. For more than three years, Trump has fumed publicly and privately about the giant commerce and services company and its founder Jeffrey P. Bezos, who is also the owner of The Washington Post.Read Replies (0)

Reader schwit1 writes: The alleged owners of Mugshots.com have been charged and arrested. These four men Sahar Sarid, Kishore Vidya Bhavnanie, Thomas Keesee, and David Usdan only removed a person's mugshot from the site if this individual paid a "de-publishing" fee, according to the California Attorney General on Wednesday. That's apparently considered extortion. On top of that, they also face charges of money laundering, and identity theft. If you read a lot of articles about crime, then you're probably already familiar with the site (which is still up as of Friday afternoon). They take mugshots, slap the url multiple times on the image, and post it on the site alongside an excerpt from a news outlet that covered the person's arrest. According to the AG's office, the owners would only remove the mugshots if the person paid a fee, even if the charges were dismissed. This happened even if the suspect was only arrested because of "mistaken identity or law enforcement error." You can read the affidavit here.Read Replies (0)
