Ask Slashdot: Could We Build A Global Wireless Mesh Network? 77

An anonymous reader wants to start a grassroots effort to build a self-organizing global radio mesh network where every device can communicate with every other device -- and without any central authority. There is nothing in the rules of mathematics or laws of physics that prevents such a system. But how would you break the problem up so it could be crowdfunded and sourced? How would you build the radios? And what about government spectrum rules... How would you persuade governments to allow for the use of say, 1%, of the spectrum for an unlicensed mesh experiment? In the U.S. it would probably take an Act of Congress to overrule the FCC but a grassroots effort with potential for major technology advances backed by celebrity scientists might be enough to tilt the issue but would there be enough motivation?
Is this feasible? Would it amass enough volunteers, advocates, and enthusiastic users? Would it become a glorious example of geeks uniting the world -- or a doomed fantasy with no practical applications. Leave your best thoughts in the comments. Could we build a global wireless mesh network?

Developer Shares A Recoverable Container Format That's File System Agnostic (github.com) 81

Long-time Slashdot reader MarcoPon writes: I created a thing: SeqBox. It's an archive/container format (and corresponding suite of tools) with some interesting and unique features. Basically an SBX file is composed of a series of sector-sized blocks with a small header with a recognizable signature, integrity check, info about the file they belong to, and a sequence number. The results of this encoding is the ability to recover an SBX container even if the file system is corrupted, completely lost or just unknown, no matter how much the file is fragmented.

Russian-Controlled Telecom Hijacks Traffic For Mastercard, Visa, And 22 Other Services (arstechnica.com) 46

An anonymous reader quotes the security editor at Ars Technica: On Wednesday, large chunks of network traffic belonging to MasterCard, Visa, and more than two dozen other financial services companies were briefly routed through a Russian government-controlled telecom under unexplained circumstances that renew lingering questions about the trust and reliability of some of the most sensitive Internet communications.

Anomalies in the border gateway protocol -- which routes large-scale amounts of traffic among Internet backbones, ISPs, and other large networks -- are common and usually the result of human error. While it's possible Wednesday's five- to seven-minute hijack of 36 large network blocks may also have been inadvertent, the high concentration of technology and financial services companies affected made the incident "curious" to engineers at network monitoring service BGPmon. What's more, the way some of the affected networks were redirected indicated their underlying prefixes had been manually inserted into BGP tables, most likely by someone at Rostelecom, the Russian government-controlled telecom that improperly announced ownership of the blocks.

Some Of The Pentagon's Critical Infrastructure Still Runs Windows 95 And 98 (defenseone.com) 104

SmartAboutThings writes: The Pentagon is set to complete its Windows 10 transition by the end of this year, but nearly 75% of its control system devices still run Windows XP or other older versions, including Windows 95 and 98. A Pentagon official now wants the bug bounty program of the top U.S. defense agency expanded to scan for vulnerabilities in its critical infrastructure.
DefenseOne raises the possibility of "building and electrical systems, HVAC equipment and other critical infrastructure laden with internet-connected sensors," with one military program manager saying "A lot of these systems are still Windows 95 or 98, and that's OK -- if they're not connected to the internet." Windows Report notes that though Microsoft no longer supports Windows XP, "the Defense Department is paying Microsoft to continue providing support for the legacy OS."

Italian Police Say Amazon Has Evaded $142 Million of Taxes (reuters.com) 82

An anonymous reader quotes a report from Reuters: Milan tax police have told Amazon they believe the world's largest online retailer has evaded around 130 million euros ($142 million) of taxes in Italy, a source close to the matter said on Friday. The allegedly unpaid taxes refer to the period between 2011 and 2015, when Amazon made revenues of around 2.5 billion euros in Italy, the source said. The tax police's findings have been handed to Milan prosecutors, the source added. Amazon issued a statement denying it had evaded any taxes, and said its profits in Italy, on which taxes are paid, had been low due to its considerable investments in the country.

Stray WiFi Signals Could Let Spies See Inside Closed Rooms (sciencemag.org) 39

sciencehabit quotes a report from Science Magazine: Your wireless router may be giving you away in a manner you never dreamed of. For the first time, physicists have used radio waves from a Wi-Fi transmitter to encode a 3D image of a real object in a hologram similar to the image of Princess Leia projected by R2D2 in the movie Star Wars. In principle, the technique could enable outsiders to "see" the inside of a room using only the Wi-Fi signals leaking out of it, although some researchers say such spying may be easier said than done. Their experiment relies on none of the billions of digital bits of information encoded in Wi-Fi signals, just the fact that the signals are clean, "coherent" waves. However, instead of recording the key interference pattern on a photographic plate, the researchers record it with a Wi-Fi receiver and reconstruct the object in a computer. They placed a Wi-Fi transmitter in a room, 0.9 meters behind the cross. Then they placed a standard Wi-Fi receiver 1.4 meters in front of the cross and moved it slowly back and forth to map out a "virtual screen" that substituted for the photographic plate. Also, instead of having a separate reference beam coming straight to the screen, they placed a second, stationary receiver a few meters away, where it had a direct view of the emitter. For each point on the virtual screen, the researchers compared the signals arriving simultaneously at both receivers, and made a hologram by mapping the delays caused by the aluminum cross. The virtual hologram isn't exactly like a traditional one, as researchers can't recover the image of the object by shining more radio waves on it. Instead, the scientists used the computer to run the radio waves backward in time from the screen to the distance where wave fronts hit the object. The cross then popped out.

Surgeon Plans To 'Reawaken' Cryogenically Frozen Brains, Transplant Them Into Someone Else's Skull (nationalpost.com) 115

Sergio Canavero, the Italian surgeon who plans to perform the world's first human head transplant within the next year, says he is preparing to reawaken cryogenically frozen brains and transplant them into someone else's skull. "In an interview with a German-language magazine, Canavero says he will attempt to bring the first brains frozen in liquid nitrogen at an Arizona-based cryogenics bank back to life 'not in 100 years,' but three years at the latest," reports National Post. From the report: Transplanting a brain only -- and not an entire head -- gets around formidable rejection issues, Canavero said, since there will be no need to reconnect and stitch up severed vessels, nerves, tendons and muscles as there is when a new head is fused onto a brain-dead donor body. Canavero allows that one "problematic" issue with brain transplants, however, would be that "no aspect of your original external body remains the same." "Your head is no longer there, your brain is transplanted into an entirely different skull," he told OOOM magazine, published by the same company that handles the Italian brain surgeon's public relations. The flamboyant neuroscientist who some ethicists have decried as "nuts" rattled the transplant world when he first outlined his plans for a human head transplant two years ago in the journal, Surgical Neurology International. Bioethicist Arthur Caplan called Canavero's latest proposal to merge head transplants with "resurrecting" the frozen dead beyond ridiculous. "People have their own doubts about whether anything can be salvaged from these frozen heads or bodies because of the damage freezing does," said Caplan, head of ethics at NYU Langone Medical Centre in New York City. "Then saying that he has some technique for making this happen, that has never been demonstrated in frozen animals, is absurd."

MIT Creates 3D-Printing Robot That Can Construct a Home Off-Grid In 14 Hours (mit.edu) 62

Kristine Lofgren writes: Home building hasn't changed much over the years, but leave it to MIT to take things to the next level. A new technology built at MIT can construct a simple dome structure in 14 hours and it's powered by solar panels, so you can take it to remote areas. MIT's 3D-printing robot can construct the entire basic structure of a building and can be customized to fit the local terrain in ways that traditional methods can't do. It even has a built-in scoop so it can prepare the building site and gather its own construction materials. You can watch a video of the 3D-printing robot in action here.

Open Ports Create Backdoors In Millions of Smartphones (bleepingcomputer.com) 102

An anonymous reader writes: "Mobile applications that open ports on Android smartphones are opening those devices to remote hacking, claims a team of researchers from the University of Michigan," reports Bleeping Computer. Researchers say they've identified 410 popular mobile apps that open ports on people's smartphones. They claim that an attacker could connect to these ports, which in turn grant access to various phone features, such as photos, contacts, the camera, and more. This access could be leveraged to steal photos, contacts, or execute commands on the target's phone. Researchers recorded various demos to prove their attacks. Of these 410 apps, there were many that had between 10 and 50 million downloads on the official Google Play Store and even an app that came pre-installed on an OEMs smartphones. "Research on the mobile open port problem started after researchers read a Trend Micro report from 2015 about a vulnerability in the Baidu SDK, which opened a port on user devices, providing an attacker with a way to access the phone of a user who installed an app that used the Baidu SDK," reports Bleeping Computer. "That particular vulnerability affected over 100 million smartphones, but Baidu moved quickly to release an update. The paper detailing the team's work is entitled Open Doors for Bob and Mallory: Open Port Usage in Android Apps and Security Implications, and was presented Wednesday, April 26, at the 2nd IEEE European Symposium on Security and Privacy that took place this week in Paris, France."

Airbnb Gives In To Regulator's Demand To Test For Racial Discrimination By Hosts (theguardian.com) 214

As part of an agreement with California regulators, Airbnb will allow the government to test for racial discrimination by hosts. The Guardian reports: The California Department of Fair Employment and Housing (DFEH) announced Thursday that it had resolved a complaint it filed against Airbnb with an agreement that forces the company to permit the state to conduct "fair housing testing" of certain hosts. That means that for the first time the San Francisco-based company is giving a regulatory body permission to conduct the kind of racial discrimination audits that officials have long used to enforce fair housing laws against traditional landlords. The DFEH's original complaint -- which had not previously been disclosed -- was based on research and a growing number of reports suggesting that hosts regularly refuse to rent to guests due to their race, a problem exposed last year under the hashtag #AirbnbWhileBlack.

Washington State Orchard Owners Look To Robots As Labor Shortage Worsens (seattletimes.com) 119

An anonymous reader quotes a report from Seattle Times: Harvesting Washington state's vast fruit orchards each year requires thousands of farmworkers, and many of them work illegally in the United States. That system eventually could change dramatically as at least two companies are rushing to get robotic fruit-picking machines to market. The robotic pickers don't get tired and can work 24 hours a day. FFRobotics and Abundant Robotics, of Hayward, California, are racing to get their mechanical pickers to market within the next couple of years. Members of the $7.5 billion annual Washington agriculture industry have long grappled with labor shortages, and depend on workers coming up from Mexico each year to harvest many crops. While financial details are not available, the builders say the robotic pickers should pay for themselves in two years. That puts the likely cost of the machines in the hundreds of thousands of dollars each. FFRobotics is developing a machine that has three-fingered grips to grab fruit and twist or clip it from a branch. The machine would have between four and 12 robotic arms, and can pick up to 10,000 apples an hour, Gad Kober, a co-founder of Israel-based FFRobotics, said. One machine would be able to harvest a variety of crops, taking 85 to 90 percent of the crop off the trees, Kober said. Humans could pick the rest. Abundant Robotics is working on a picker that uses suction to vacuum apples off trees.

Apple, Tesla Ask California To Change Its Proposed Policies On Self-Driving Car Testing (reuters.com) 28

Tesla and Apple have asked the state of California to change its proposed policies on self-driving cars to allow companies to test vehicles without traditional steering wheels and controls or human back-up drivers, among other things. Reuters reports: In a letter made public Friday, Apple made a series of suggested changes to the policy that is under development and said it looks forward to working with California and others "so that rapid technology development may be realized while ensuring the safety of the traveling public." Waymo, the self-driving car unit of Google parent company Alphabet Inc, Ford Motor Co, Uber Technologies Inc, Toyota Motor Corp, Tesla Motors Inc and others also filed comments suggesting changes. Apple said California should revise how companies report self-driving system "disengagements." California currently requires companies to report how many times the self-driving system was deactivated and control handed back to humans because of a system failure or a traffic, weather or road situation that required human intervention. Apple said California's rules for development vehicles used only in testing could "restrict both the design and equipment that can be used in test vehicles." Tesla said California should not bar testing of autonomous vehicles that are 10,000 pounds (4,535 kg) or more. Tesla also said California should not prohibit the sale of non-self-driving vehicles previously used for autonomous vehicle testing.

WikiLeaks Reveals the 'Snowden Stopper': CIA Tool To Track Whistleblowers (zerohedge.com) 89

schwit1 quotes a report from Zero Hedge: As the latest installment of it's "Vault 7" series, WikiLeaks has just dropped a user manual describing a CIA project known as "Scribbles" (a.k.a. the "Snowden Stopper"), a piece of software purportedly designed to allow the embedding of "web beacon" tags into documents "likely to be stolen." The web beacon tags are apparently able to collect information about an end user of a document and relay that information back to the beacon's creator without being detected. Per WikiLeaks' press release. But, the "Scribbles" user guide notes there is just one small problem with the program: it only works with Microsoft Office products. So, if end users use other programs such as OpenOffice of LibreOffice then the CIA's watermarks become visible to the end user and their cover is blown.

Amazon's Alexa Can Now Whisper, Bleep Out Swear Words, and Change Its Pitch (theverge.com) 34

An anonymous reader quotes a report from The Verge: Amazon is trying to make its Alexa voice assistant sound more humanlike. Up until now, the female-sounding voice maintained an even, monotone cadence whenever speaking, but with Amazon's new Speech Synthesis Markup Language that the company introduced this week, Alexa can whisper, vary its speaking speed, and bleep out words. Developers can also add pauses, change the pronunciation of a word, spell a word out, add audio snippets, and insert special words and phrases into their skill. The Verge notes that "the language markups are [only] available to developers in the U.S., U.K. and Germany." Amazon will also be hosting a webinar on May 18th on the new code.

IT Leaders Will Struggle To Meet Future Demands, Study Says (betanews.com) 107

When it comes to meeting future demands, IT leaders in the UK are lagging behind those in Germany and the US. From a report: This is according to a new report by Brocade, entitled Global Digital Transformation Skills Study. The report is based on a survey of 630 IT leaders in the US, UK, France, Germany, Australia and Singapore. It says that organizations are "at a tipping point" -- a point in time when technology demands are just about to outstrip the skills supply. Consequently, those that train their staff now and prepare for the future in that respect are the ones that are setting themselves up for a successful future. Almost three quarters (74 percent) of IT leaders in the UK see IT departments as either "very important" or "critical" to both innovation and the growth of their business. But the same woes reman, as almost two thirds (63 percent) think they'll struggle to find the right people in the next year.

Elon Musk Outlines His 'Boring' Vision For Traffic-Avoiding Tunnels (axios.com) 155

Tesla CEO Elon Musk revealed new details about his futuristic tunnel-boring project during his TED talk on Friday. Ina Fried, writing for Axios: In an appearance at the TED conference in Vancouver, Musk showed off a new video visualization of electric skates transporting cars in a narrow tunnel, then raising them back to street level in a space as small as two parking spaces. Inside the tunnels, Musk said cars could travel as fast as 200 kilometers per hour (roughly 130 MPH). "You should be able to go from say Westwood to LAX in 5-6 minutes," the Tesla and SpaceX founder said, adding he is spending only 2-3 percent on the tunnel effort. The Boring Company is currently building a demo tunnel in SpaceX's parking lot, but will need permits from the city of Los Angeles to extend beyond the property line. Musk added, "I'm not trying to be anyone's savior. I'm just trying to think about the future and not be sad." You can watch the video here.

An Open Letter on DRM To the Inventor of the Web, From the Inventor of Net Neutrality (boingboing.net) 46

Tim Wu, a law professor at the Colombia University, and best known for coining the term "net neutrality," has published an open letter to Tim Berners-Lee, the creator of the web and director of the World Wide Web Consortium (W3C). In the letter, Wu has asked Berners-Lee to "seriously consider extending a protective covenant to legitimate circumventers who have cause to bypass EME, should it emerge as a W3C standard." Cory Doctorow, writes for BoingBoing: But Wu goes on to draw a connection between the problems of DRM and the problems of network discrimination: DRM is wrapped up in a layer of legal entanglements (notably section 1201 of America's Digital Millennium Copyright Act), which allow similar kinds of anticompetitive and ugly practices that make net neutrality so important. This is a live issue, too, because the W3C just held the most contentious vote in its decades-long history, on whether to publish a DRM standard for the web without any of the proposed legal protections for companies that create the kinds of competing products and services that the law permits, except when DRM is involved. As Wu points out, this sets up a situation where the incumbents get to create monopolies that produce the same problems for the open web that network neutrality advocates -- like Berners-Lee -- worry about.

Slashdot Asks: Should an Employee Be Fired For Working On Personal Side Projects During Office Hours? (quora.com) 380

An anonymous reader writes: I found this article that talks about whether an engineer should be fired if s/he is working on a side project. Several people who have commented in the thread say that the employer should first talk to the person and understand why they are working on personal projects during the office hours. One reason, as many suggested, could be that the employee might not have been fairly compensated despite being exceptionally good at the job. In which case, the problem resides somewhere in the management who has failed to live up to the expectations. What do you folks think? Let's not just focus on engineers, per se. It could be an IT guy (who might have a lot of free time in hand), or a programmer.

Amazon Confirms Advertising Will Become a 'Meaningful' Part of Its Business (thedrum.com) 69

An anonymous reader shares a report: Amazon's advertising business has loomed quietly in the digital media space for some time but the online behemoth has given the clearest indication yet that it will now come to the fore. Advertisers and agencies have been hearing Amazon-sized footsteps for some time but until now the business has erred away from revealing too much. However, on its latest earnings call Amazon was asked by one analyst as to whether advertising could become a more "meaningful part of the business" over the near to mid-term. "It's pretty early in the days with advertising but we're very pleased with the team we have and the results," said Amazon's chief financial officer Brian Olsavsky in response to another analyst query. "Our goal is to be helpful to consumers and enhance their shopping or their viewing experience with targeted recommendations, and we think a lot of the information we have and preferences of customers and recommendations help us do that for customers."
