Submission + - Report outlines SpaceX's plans for Starship launches from KSC (spacenews.com)

schwit1 writes: SpaceX plans to build facilities at the Kennedy Space Center’s Launch Complex 39A for launches and, eventually, landings of its next-generation launch vehicle, according to a newly released report.

An environment assessment prepared by SpaceX, and released by NASA Aug. 1, discusses plans to develop additional facilities at LC-39A, which currently hosts Falcon 9 and Falcon Heavy launches, for use by the company’s Starship vehicle and its Super Heavy booster.

The plans outlined in the document call for the construction of a new launch mount at the complex near the existing one used by the Falcon 9 and Heavy. The modifications to the pad would also include a tank farm for the methane fuel used by the Raptor engines that power Starship and Super Heavy.

The Super Heavy booster would land at a ship in the ocean downrange from the launch site, although the report noted that SpaceX may later have the booster return to land. The Starship upper stage would initially land at the company’s existing Landing Zone 1 at Cape Canaveral Air Force Station, but the company plans to build a pad near the new launch mount at LC-39A for to support Starship landings at a future date.

The facilities will be able to support up to 24 Starship/Super Heavy launches a year.

Submission + - Georgia Department of Public Safety hit by ransomware attack.

McFortner writes: On July 27th the Georgia Department of Public Safety announced that they got hit by a ransomware attack. When I went in to get a copy of an accident report this Friday, the officer at the Henry County, GA, police department told me that at least 7 counties in the Atlanta area were hit at the same time and they had no way of knowing when their computers would be back up. They suggest to anybody needing a report to call them first to see if by any chance the system is back up and the report is finished and can be picked up.

Submission + - The ENIAC Programmers (boingboing.net)

AmiMoJo writes: The programmers of the ENIAC — the Electronic Numerical Integrator and Computer, the first modern computer — whose first programmers were six women: Kathleen McNulty Mauchly Antonelli, Jean Jennings Bartik, Betty Snyder Holberton, Marlyn Wescoff Meltzer, Ruth Lichterman Teitelbaum and Frances Bilas Spence.

The ENIAC programmers had to invent programming as we know it, working without programming codes (these were invented a few years later for UNIVAC by Betty Holberton): they "broke down the differential calculus ballistics trajectory program" into small steps the computer could handle, then literally wired together the program by affixing cables and flicking the machine's 3,000 switches in the correct sequences. To capture it all, they created meticulous flowcharts that described the program's workings.

Submission + - SPAM: These are the Internet of Things devices that are most targeted by hackers 1

An anonymous reader writes:

Internet-connected security cameras account for almost half of the Internet of Things devices that are compromised by hackers even as homes and businesses continue to add these and other connected devices to their networks.

Research from cybersecurity company SAM Seamless Network found that security cameras represent 47 percent of vulnerable devices installed on home networks.

Figures from the security firm suggest that the average device is the target of an average of five attacks per day, with midnight the most common time for attacks to be executed – it's likely that at this time of the night, the users will be asleep and not paying attention to devices, so won't be witness to a burst of strange behavior.

The US Govt needs to block all imports of internet devices using the same methods used for importing fruit from central america: periodic inspections. Device gets rejected if it has non-essential ports open, hard coded or generic passwords, no automated patching for at least 4 years, etc

Submission + - Tacoma-based Snopes is locked in a nasty legal dispute (seattletimes.com)

jader3rd writes: After more than two decades battling internet hoaxes, retouched photos, and other fake news, David Mikkelson, co-founder of Snopes, faces a much larger and more existential adversary.

Since 2017, Mikkelson has been locked in a nasty legal dispute with former business associates over control of Snopes, the pioneering fact-checking website that Mikkelson launched with a former wife in 1994 and which he now runs with his current wife from their house in Tacoma.

The dispute, which is playing out in the California courts, has generated claims and counterclaims of financial mismanagement, conspiracy and embezzlement. Mikkelson stands accused of, among other things, using company funds for “lavish” vacations, while he in turn levels accusations of fraud.

Submission + - Chelating agent selectively grabs uranium from oceans (acs.org)

webofslime writes: The world’s oceans contain some 4 billion metric tons of dissolved uranium. That’s roughly 1,000 times as much as all known terrestrial sources combined, and enough to fuel the global nuclear power industry for centuries. But the oceans are so vast, and uranium’s concentration in seawater is so low—roughly 3 ppb—that extracting it remains a formidable challenge. That task may have just become easier thanks to a new adsorbent material based on a bioinspired chelating agent (Nat. Commun. 2019 DOI: 10.1038/s41467-019-08758-1).

Researchers have been looking for ways to extract uranium from seawater for more than 50 years. In the 1980s, surveys pointed to amidoxime-type chelating agents, which have a knack for latching onto uranyl ions, the aqueous form of uranium.

Nearly 20 years ago, the Japan Atomic Energy Agency (JAEA) confirmed that amidoxime-functionalized polymers could soak up uranium reliably even under harsh marine conditions. But that type of adsorbent has not been implemented on a large scale because it has a higher affinity for vanadium than uranium. Separating the two ions raises production costs.

Alexander S. Ivanov of Oak Ridge National Laboratory, together with colleagues there and at Lawrence Berkeley National Laboratory and other institutions, may have come up with a solution. Using computational methods, the team identified a highly selective triazine chelator known as H2BHT that resembles iron-sequestering compounds found in bacteria and fungi. Starting with low-cost reagents, the team prepared fibers containing polyethylene and polyacrylic acid, functionalized them with H2BHT (shown), and analyzed their performance as adsorbents.

Submission + - Simulation Showcases the Ferocious Power of a Solar Flare (astroengine.com)

astroengine writes: For the first time, scientists have created a computer model that can simulate the evolution of a solar flare, from thousands of miles below the photosphere to the eruption itself in the lower corona — the sun’s multimillion degree atmosphere. And the results are not only scientifically impressive, the visualization is gorgeous.

Submission + - GOP lawmaker seeks 'virtual Congress' with telecommuting (thehill.com)

Applehu Akbar writes: New Mexico Congressman Steve Pierce has an idea: why not use today's videoconferencing tech to allow representatives to perform most Congressional activity from their home districts? Because Congresspeople serve short terms and campaign largely on constituent service, they have to spend a large percentage of their time shuttling between home and Washington. Virtualizing most of their Washington presence would save fuel and energy while giving them more time with their constituents.

In addition, there could be a long-term societal benefit in making Congress less vulnerable to lobbyist influence by keeping them out of the Beltway.

Submission + - HMV teeters on the brink of collapse

Retron writes: The UK's largest High Street retailer of CDs, DVDs and Blu-rays has called in administrators for the second time in six years. The sector as a whole is struggling thanks to the rise of streaming services from the likes of Netflix, with customers increasingly shunning physical media in favour of lower-quality (but more convenient) subscription streaming services.

HMV made losses last year of £7.5m on sales of £278m. Business rates alone (the tax for being on the High Street) accounted for £15m of costs. This is despite HMV selling roughly a quarter of all physical DVDs and Blu-rays in the UK last year, as well as around a third of all physical music recordings. Indeed, the Telegraph reports HMV overtook Amazon in terms of sales of physical DVDs this year in the UK, as Amazon has focused more on its streaming services.

However, demand is expected to decline by 17% next year, heaping further woes on a company struggling to adapt to modern trends. With a bleak future ahead for physical media sales, it remains to be seen whether HMV — which has been around since 1921 — can survive to see its one hundredth anniversary.

Submission + - The Internet Is Mostly Fake Now (nymag.com) 3

AmiMoJo writes: In late November, the Justice Department unsealed indictments against eight people accused of fleecing advertisers of $36 million in two of the largest digital ad-fraud operations ever uncovered. Hucksters infected 1.7 million computers with malware that remotely directed traffic to “spoofed” websites.

How much of the internet is fake? Studies generally suggest that, year after year, less than 60 percent of web traffic is human; some years, according to some researchers, a healthy majority of it is bot. For a period of time in 2013, the Times reported this year, a full half of YouTube traffic was “bots masquerading as people,” a portion so high that employees feared an inflection point after which YouTube’s systems for detecting fraudulent traffic would begin to regard bot traffic as real and human traffic as fake. They called this hypothetical event “the Inversion.”

In the future, when I look back from the high-tech gamer jail in which President PewDiePie will have imprisoned me, I will remember 2018 as the year the internet passed the Inversion, not in some strict numerical sense, since bots already outnumber humans online more years than not, but in the perceptual sense. Everything that once seemed definitively and unquestionably real now seems slightly fake; everything that once seemed slightly fake now has the power and presence of the real. The “fakeness” of the post-Inversion internet is less a calculable falsehood and more a particular quality of experience — the uncanny sense that what you encounter online is not “real” but is also undeniably not “fake,” and indeed may be both at once, or in succession, as you turn it over in your head.

Submission + - icrosoft announces Project Mu, an open-source release of the UEFI core (betanews.com)

Mark Wilson writes: Microsoft has a new open source project — Project Mu. This is the company's open-source release of the Unified Extensible Firmware Interface (UEFI) core which is currently used by Surface devices and Hyper-V.

With the project, Microsoft hopes to make it easier to build scalable and serviceable firmware, and it embraces the idea of Firmware as a Service (FaaS). This allows for fast and efficient updating of firmware after release, with both security patches and performance-enhancing updates.

Submission + - Ask Slashdot: Why Don't HDR TVs Have An sRGB Or AdobeRGB Rating?

dryriver writes: As anyone who buys professional computer monitors knows, the dynamic range of the display device you are looking at can be expressed quite usefully in terms of percentage sRGB coverage and percentage AdobeRGB coverage. The higher the percentage for each, the better and wider the dynamic range of the screen panel you are getting. People who work with professional video and photographs typically aim for a display that has 100 percent sRGB coverage and at least 70 to 80 percent AdobeRGB coverage. Laptop review site Notebookcheck ( https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fwww.notebookcheck.net%2F ) for example uses professional optical testing equipment to check whether the advertised sRGB and AdobeRGB percentages and brightness in nits for any laptop display panel hold up in real life. This being the case, why do quote on quote "High Dynamic Range" capable TVs — which seem to be mostly 10 bits per channel to begin with — not have an sRGB or AdobeRGB rating quoted anywhere in their technical specs? Why don't professional TV reviewers use optical testing equipment — readily available — to measure the real world dynamic range of HDR or non-HDR TVs objectively, in hard numbers? Why do they simply say "the blacks on this TV were deep and pleasing, and the lighter tones were..." when this can be expressed better and more objectively in measured numbers or percentages? Do they think consumers are too unsophisticated to understand a simple number like "this OLED TV achieves a fairly average 66 percent AdobeRGB coverage"?
