Engineers Develop 'Ultrarope' For World's Highest Elevator 247

Posted by Soulskill
from the for-when-super-rope-just-doesn't-cut-it dept.
HughPickens.com writes: Halfway up the Shard, London's tallest skyscraper, you are asked to step out of the elevator at the transfer floor, or "sky lobby," a necessary inconvenience in order to reach the upper half of the building, and a symptom of the limits of elevators today. To ascend a mile-high (1.6km) tower using the same technology could necessitate changing elevators as many as 10 times. Elevators traveling distances of more than 500m [1,640 ft] have not been feasible because the weight of the steel cables themselves becomes so great. Now, after nine years of rigorous testing, Kone has released Ultrarope — a material composed of carbon-fiber covered in a friction-proof coating that weighs a seventh of the steel cables, making elevators of up to 1km (0.6 miles) in height feasible to build.

Kone's creation was chosen to be installed in what's destined to become the world's tallest building, the Kingdom Tower in Jeddah, Saudi Arabia. When completed in 2020, the tower will stand a full kilometer in height, and will boast the world's tallest elevator at 660m (2,165ft). A 1km-tall tower may seem staggering, but is this the build-able limit? Most probably not, according to Dr. Sang Dae Kim. "With Kingdom Tower we now have a design that reaches around 1 km in height. Later on, someone will push for 1 mile, and then 2 km," says Kim. He adds that, technically speaking, 2 km might be possible at the current time. Anything higher would require new materials and building techniques.

+ - White House Drone Incident Exposes Key Security Gap

Submitted by HughPickens.com
HughPickens.com (3830033) writes "The Washington Post reports that the intrusion by a recreational drone onto the White House lawn has exposed a security gap at the compound that the Secret Service has spent years studying but has so far been unable to fix. Commercial technology is available that can use a combination of sensitive radar and acoustic trackers to detect small drones, though coming up with an effective way to stop them has been more elusive. "To do something about the problem, you have to find it, you have to track it, you have to identify it and you have to decide what to do with it,” says Frederick F. Roggero. “But especially in an urban environment, it would be tough to detect and tough to defeat kinetically without shooting it down and causing collateral damage.” Most recreational drones, like the one that crashed Monday, weigh only a few pounds and lack the power to do much harm. Larger models that can carry payloads of up to 30 pounds are available on the market and are expected to become more common. The FAA imposes strict safety regulations on drones flown by government agencies or anyone who operates them for commercial purposes. In contrast, hardly any rules apply to people who fly drones as a hobby, other than FAA guidelines that advise them to keep the aircraft below 400 feet and five miles from an airport. “With the discovery of an unauthorized drone on the White House lawn, the eagle has crash-landed in Washington," says Senator Charles Schumer. "There is no stronger sign that clear FAA guidelines for drones are needed.""

+ - EFF Unveils Plan For Ending Mass Surveillance-> 1

Submitted by Anonymous Coward
An anonymous reader writes "The Electronic Frontier Foundation has published a detailed, global strategy for ridding ourselves of mass surveillance. They stress that this must be an international effort — while citizens of many countries can vote against politicians who support surveillance, there are also many countries where the citizens have to resort to other methods. The central part of the EFF's plan is: encryption, encryption, encryption. They say we need to build new secure communications tools, pressure existing tech companies to make their products secure against everyone, and get ordinary internet-goers to recognize that encryption is a fundamental part of communication in the surveillance age. They also advocate fighting for transparency and against overreach on a national level. "[T]he more people worldwide understand the threat and the more they understand how to protect themselves—and just as importantly, what they should expect in the way of support from companies and governments—the more we can agitate for the changes we need online to fend off the dragnet collection of data." The EFF references a document created to apply the principles of human rights to communications surveillance, which they say are "our way of making sure that the global norm for human rights in the context of communication surveillance isn't the warped viewpoint of NSA and its four closest allies, but that of 50 years of human rights standards showing mass surveillance to be unnecessary and disproportionate.""

Google Explains Why WebView Vulnerability Will Go Unpatched On Android 4.3 578

Posted by samzenpus
from the no-patch-for-you dept.
MojoKid writes If you're running Android 4.3 or earlier, you're pretty much out of luck when it comes to a baked-in defense against a WebView vulnerability that was discovered earlier this month by security analyst Tod Beardsley. The vulnerability leaves millions of users open to attack from hackers that choose to exploit the security hole. WebView is a core component of the Android operating system that renders web pages. The good news is that the version of WebView included in Android 4.4 KitKat and Android 5.0 Lollipop is based on Chromium and is not affected by the vulnerability. The bad news is that those running Android 4.3 and earlier are wide open, which means that 60 percent of Android users (or nearly one billion customers) are affected. What's most interesting is that Google has no trouble tossing grenades at the feet of Microsoft and Apple courtesy of its Project Zero program, but doesn't seem to have the resources to fix a vulnerability that affects a substantial portion of the Android user base.

Anonymous Asks Activists To Fight Pedophiles In 'Operation Deatheaters' 408

Posted by timothy
from the or-have-you-stopped-beating-her? dept.
HughPickens.com writes The Independent reports that hacktivist group Anonymous, in a project named Operation DeathEaters, is calling for help in its fight against international pedophile networks, or what it calls the "paedosadist industry" and has issued a video instructing activists on how they can aid in the operation. The Anonymous project is intended to break what it says is a conspiracy of silence among sympathetic politicians, police and mainstream media to downplay the full extent of the online child sex industry. "The premise behind OpDeathEaters is to expose high level complicity, obstruction of justice and cover-up in the paedo-sadist industry in order to show the need for independent inquiries," says Heather Marsh, an online activist who is helping to co-ordinate the operation and describes herself as an "old friend" of Anonymous. The Anonymous database, which will be hosted on the GitHub online repository, promises to collate cases from all around the world, cross-referencing connections within sub-groups including the police, armed forces, schoolteachers, politicians, media, academics and religious organisations. The database's ultimate purpose has yet to be fully determined, but in the first instance the group says it wants to shut down the child-sex industry by "dismantling the power structure which held it there" and by "educating to create a cultural change".

The group is calling on volunteers to help with the ongoing work, which has been divided into three steps. The first is about collecting "all the factual information," second is to "share that information as widely as possible," and the third step is "to set up an independent, internationally linked, inquiry into all the areas which do not appear to have been investigated properly." Activists point to the muted media coverage given to a recent case in Washington DC in which Michael Centanni, a senior Republican fundraiser, was charged with child sex offences after investigators traced transmissions of child pornography to his computers in his basement. The case was not covered by The Washington Post or the New York Times, and was only picked up by a local NBC affiliate state and The Washington Examiner, a small conservative paper in the city. According to the court filings, Centanni was found in possession of 3,000 images, many apparently filmed in his own bedroom, including one showing a man raping a five-year-old girl who cries "no" and "mommy" while the man says "good baby" and "stop crying," according to one filing.

Smartphones, Tablets and EBay Send SkyMall To Chapter 11 65

Posted by timothy
from the not-to-mention-deal-extreme-and-amazon dept.
alphadogg writes SkyMall, the quirky airline catalog, looks as though it may be grounded before long. Parent company Xhibit has filed for Chapter 11 bankruptcy protection and seeks to sell its assets. In an SEC filing, Xhibit explains that it has fallen victim to an "intensely competitive" direct marketing retail industry that now includes the likes of eBay and Amazon.com. Smartphones and tablets are largely to blame for SkyMall's downfall, according to the SEC filing. "Historically, the SkyMall catalog was the sole in-flight option for potential purchasers of products to review while traveling. With the increased use of electronic devices on planes, fewer people browsed the SkyMall in-flight catalog."

Behind the MOOC Harassment Charges That Stunned MIT 376

An anonymous reader writes: The complainant in a sexual harassment case has come forward and told her story about what happened when she was a student in a MOOC led by a rockstar professor. "It would take almost a year before Harbi, with the help of MIT’s investigators, said she came to understand that Lewin’s interest in her was not motivated by empathy, and that their first conversations included inappropriate language. Shortly after contacting her, Harbi said, Lewin quickly moved their friendship into uncomfortable territory, and she was pushed to participate in online sexual role-playing and send naked pictures and videos of herself."

The Tech Industry's Legacy: Creating Disposable Employees 263

Posted by Soulskill
from the train-your-replacement-to-train-your-replacement dept.
An anonymous reader writes: VentureBeat is running an indictment of the tech industry's penchant for laying off huge numbers of people, which they say is responsible for creating a culture of "disposable employees." According to recent reports, layoffs in the tech sector reached over 100,000 last year, the highest total since 2009. Of course, there are always reasons for layoffs: "Companies buy other companies and need to rationalize headcount. And there's all that disruption. Big companies, in particular, are seeing their business models challenged by startups, so they need to shed employees with skills they no longer need, and hire people with the right skills."

But the article argues that this is often just a smokescreen. "The notion here is that somehow these companies are backed into a corner, with no other option than to fire people. And that's just not true. These companies are making a choice. They're deciding that it's faster and cheaper to chuck people overboard and find new ones than it is to retrain them. The economics of cutting rather than training may seem simple, but it's a more complex calculation than most people believe. ... Many of these companies are churning through employees, laying off hundreds on one hand, while trying to hire hundreds more."

+ - Interior of burnt Herculaneum scroll read for first time 1

Submitted by Solandri
Solandri (704621) writes "When Mt. Vesuvius erupted in A.D. 79, it destroyed a library of classical works in Herculaneum. The papyrus scrolls weren't incinerated, but were instead carbonized by the hot gases. The resulting black carbon cylinders have mostly withstood attempts to read their contents since their discovery. Earlier attempts to unfurl the scrolls yielded some readable material, but were judged too destructive. Researchers decided to wait for newer technology to be invented that could read the scrolls without unrolling them.

Now, a team led by Dr Vito Mocella from the National Research Council's Institute for Microelectronics and Microsystems (CNR-IMM) in Naples, Italy has managed to read individual letters inside one of the scrolls. Using a form of x-ray phase contrast tomography, they were able to ascertain the height difference (about 0.1mm) between the ink of the letters and the papyrus fibers which they sat upon. Due to the fibrous nature of the papyrus and the carbon-based ink, regular spectral and chemical analysis had thus far been unable to distinguish the ink from the paper. Further complicating the work, the scrolls are not in neat cylinders, but squashed and ruffled as the hot gases vaporized water in the papyrus and distorted the paper.
