dryriver writes: For those who are unfamiliar with the story, from 1901-1902, inventor Nikola Tesla had a 187-foot-tall experimental wireless electricity transmission tower called the "Wardenclyffe Tower" built in Shoreham, New York. Tesla believed that it was possible to generate electrical power on a large scale in one part of the world and transmit that electrical power to electrical receivers in far away parts of the world wirelessly, using parts of Earth's atmosphere as the conducting medium. Tesla had huge problems getting the project financed -- powerful banker J.P. Morgan didn't play along and U.S. President Woodrow Wilson didn't help a pleading Tesla either. An excerpt from a Wardenclyffe documentary shows the tower finally being dynamited and sold for scrap in 1917. The Wardenclyffe Tower never reached operational status; wireless electrical transmission between continents never happened; Tesla became an emotionally broken man who died regretting that he did not manage to finish his life's work; and to this day nobody knows exactly how the Wardenclyffe Tower was supposed to function technically. To the question: Do you believe that Tesla's dream of electrical devices anywhere in the world essentially being able to draw electrical power from the sky with a relatively simple antenna could have worked, had he gotten the necessary funding to complete his experiments?

"Anthony Levandowski, the controversial engineer at the heart of a lawsuit between Uber and Waymo, claims to have built an automated car that drove from San Francisco to New York without any human intervention," reports the Guardian. Levandowski told the Guardian that he completed the 3,099-mile journey on October 30th using a modified Toyota Prius, which "used only video cameras, computers and basic digital maps." From the report: Levandowski told the Guardian that, although he was sitting in the driver's seat the entire time, he did not touch the steering wheels or pedals, aside from planned stops to rest and refuel. "If there was nobody in the car, it would have worked," he said. If true, this would be the longest recorded road journey of an autonomous vehicle without a human having to take control. Elon Musk has repeatedly promised, and repeatedly delayed, one of his Tesla cars making a similar journey. A time-lapse video of the drive, released to coincide with the launch of Levandowski's latest startup, Pronto.AI, did not immediately reveal anything to contradict his claim. But Levandowski has little store of trust on which to draw.

Rolls-Royce announced today that it is teaming up with robotics experts at Harvard University and University of Nottingham to develop tiny "cockroach" robots that can crawl inside aircraft engines to spot and fix problems. These robots will be able to speed up inspections and eliminate the need to remove an engine from an aircraft for repair work to take place. CNBC reports: Sebastian de Rivaz, a research fellow at Harvard Institute, said the inspiration for their design came from the cockroach and that the robotic bugs had been in development for eight years. He added that the next step was to mount cameras on the robots and scale them down to a 15-milimeter size. De Rivaz said that once the robots had performed their duty they could be programed to leave the engine or could simply be "flushed out" by the engine itself.

Also under development are "snake" robots that are flexible enough to travel through an engine like an endoscope. These would enter through a combustion chamber and would inspect damage and remove any debris. The second "snake" would deposit a patch repair that would sit temporarily until the engine was ready for full repair. No schedule is placed on when the crawling robots will be available. You can view animations of each robot type here.

Christine Peterson is a long-time futurist who co-founded the nanotech advocacy group the Foresight Institute in 1986. One of her favorite tasks has been contacting the winners of the institute's annual Feynman Prize in Nanotechnology, but she also coined the term "Open Source software" for that famous promotion strategy meeting in 1998. Now Christine's agreed to answer questions from Slashdot readers. We'll pick the very best questions and forward them along for answers.

Interestingly, Christine was also on the Editorial Advisory Board of NASA's Nanotech Briefs, and on the state of California's nanotechnology task force. Her tech talks at conferences include "Life Extension for Geeks" at Gnomedex and "Preparing for Bizarreness: Open Source Physical Security" at the 2007 Singularity Summit. Another talk argues that the nanotech revolution will be like the information revolution, except that "Instead of with bits, we should do it with atoms," allowing molecule-sized machines that can kill cancer and repair DNA. Her most recent publication is "Cyber, Nano, and AGI RIsks: Decentralized Approaches to Reducing Risks." Christine graduated from MIT with a bachelors in chemistry.

So leave your best questions in the comments. (Ask as many questions as you'd like, but please, one per comment.) We'll pick the very best questions and forward them along for answers.

An anonymous reader shares a report: Kit Kat's maker Nestle has been accused of copying Breakout, the 1970s computer game, in a marketing campaign. Atari, the company behind some of the most popular early video games, has filed a suit alleging Nestle knowingly exploited the game's look and feel. The advert showed a game similar to Breakout but where the bricks were replaced with single Kit Kat bars. Nestle said it was aware of the lawsuit and would defend itself "strongly" against the allegations. Breakout was created as a successor to "Pong" by Apple founders, Steve Wozniak and Steve Jobs. In the advert, which is titled "Kit Kat: Breakout", a row of people, of varying ages and appearance, share a sofa and play a video game during their work break. In the game depicted, a primitive paddle moves side-to-side to bounce a ball into a collision with the horizontal bars ranged across the top of the screen.

New submitter Aliciadivo writes: A nasty vulnerability found in Axis security cameras could allow hackers to take full control of several types of Internet of Things devices, and in some cases, software programs, too. The Senrio research team found that devices and software programs using an open source software library called gSOAP to enable their product to communicate to the internet could be affected. Stephen Ridley, founder of Senrio, said: "I bet you all these other manufacturers have the same vulnerability throughout their product lines as well. It's a vulnerability in virtually every IoT device [...] Every kind of device you can possibly think of." A spokesperson for ONVIF, an electronics industry consortium that includes Axis and has includes some members that use gSOAP, said it has notified its members of the flaw, but it's not "up to each member to handle this in the way they best see fit." Also, gSOAP "is not in any way mandated by the ONVIF specifications, but as SOAP is the base for the ONVIF API, it is possible that ONVIF members would be affected." Hundreds of thousands of devices might be affected, as a search for the term "Axis" on Shodan, an engine that scours the internet for vulnerable devices, returns around 14,000 results. You can view Senrio Labs' video on the exploit (which they refer to as the "Devil's Ivy Exploit") here.

An anonymous reader quotes a report from Adweek: Elon Musk is well aware that Tesla's superfans love to make unauthorized commercials for the brand, given that Tesla doesn't make its own (and, given the power of word of mouth, doesn't really need to). But it has taken a fifth-grade girl to convince him to actually run a fan-made ad. "Dear Elon Musk, I'm Bria from Ms. Esparza's 5th grade class," she wrote to the Tesla founder in a letter that her father (a writer for InsideEVs.com) also posted to Twitter. "I have noticed that you do not advertise, but many people make homemade commercials for Tesla and some of them are very good, they look professional and they are entertaining. So, I think that you should run a competition on who can make the best homemade Tesla commercial and the winners will get their commercial aired." Within an hour of the Twitter post, Musk -- who apparently is as smart as a fifth grader -- brightened to the idea. "Thank you for the lovely letter. That sounds like a great idea. We'll do it!" he wrote. Two of the fan-made, cinematography-rich commercials mentioned in the report include the 2014 spot called "Modern Spaceship," and "Fireflies," which was directed by Parachute's Sam O'Hare. What's particularly neat about the "Fireflies" ad is that it was completely CGI.

An anonymous reader writes from a report via BleepingComputer: Downloading and trying to open Windows DRM-protected multimedia files can deanonymize Tor Browser users and reveal their real IP addresses, security researchers from Hacker House have warned. On Windows, multimedia files encoded with special Microsoft SDK will automatically open an IE window and access a URL to check the file's license. Since this request is sent outside of the Tor Browser and without user interaction, this can be used to ping law enforcement servers and detect the user's real IP address and other details. For example, law enforcement could host properly signed DRM-protected files on sites pretending to host child pornography. When a user would try to view the file, the DRM multimedia file would use Internet Explorer to ping a server belonging to the law enforcement agency. The same tactic can also be used to target ISIS militants trying to view propaganda videos, illegal drug and weapons buyers trying to view video product demos, political dissidents viewing news videos, and more. A video of the attack is available here.

Kara Swisher, reporting for Recode: Bill Campbell, who garnered the name "The Coach" for the sage advice and counsel he gave numerous tech leaders from Apple's Steve Jobs to Google's Larry Page to Amazon's Jeff Bezos, has died. He was battling with cancer. News of his passing popped up on Facebook early this morning and many prominent tech players also confirmed the death to me, which came after a long battle with cancer. It is a big loss for Silicon Valley, given the impact a man who said he did not even know how to do HTML had by virtue of wisdom alone. But he was not without tech chops. Campbell ran companies like Intuit and worked in key jobs at Apple, Claris and Go, and also served on a plethora of boards, including Columbia University, Intuit and Apple. He has been a longtime adviser to Google execs including Page and Eric Schmidt -- and really just about every major tech executive you could think of at some point.VentureBeat interviewed Campbell in 2011, in which he shared coaching tips.

theodp writes: The very first proposal President Obama put forth in his final State of the Union address Tuesday night for his remaining year in office was "helping students learn to write computer code." While the President wants every student to learn CS, NPR notes that getting a new, complex, technical subject onto the agendas of our public schools is a massive challenge, prompting it to ask, How Would That Work? That Microsoft CEO Satya Nadella attended the SOTU address as Michelle Obama's guest suggests the President is counting on the kindness of tech titans to help make things happen. Microsoft and Obama have worked together to try to get CS in the schools since at least 2006, when Microsoft announced a $1 million donation to NCWIT, which it indicated would facilitate "taking the discussion to a national stage" at a Washington, D.C. Innovation and Diversity Town Hall co-sponsored by the NSF and keynoted by then-Senator Barack Obama. "Most of all, what inspires me about this program [NCWIT] are the prospects of my two daughters," Obama said at the time (video). "I want them to go as far as their dreams may take them. And, unfortunately because of long historic discrimination in the areas of gender, we can't be assured of that."

JustAnotherOldGuy writes: Peter "brokep" Sunde, co-founder of The Pirate Bay, has built a machine that makes 100 copies per second of Gnarls Barkley's "Crazy," storing them in /dev/null (which is of course, deleting them even as they're created). The machine, called a "Kopimashin," is cobbled together out of a Raspberry Pi, some hacky python that he doesn't want to show anyone, and an LCD screen that calculates a running tally of the damages he's inflicted upon the record industry through its use. The 8,000,000 copies it makes every day costs the record industry $10m/day in losses. At that rate, they'll be bankrupt in a few weeks at most.

theodp writes: Reporting on Google exec Susan Wojcicki's appearance at DreamForce, Inc.'s Tess Townsend writes: "The YouTube CEO said her daughter had stated point-blank that she did not like computers, so Wojcicki enrolled her in a computer camp. The camp made her daughter dislike tech even more. Wojcicki reported her daughter came back saying, 'Everyone in the class was a boy and nobody was like me and now I hate computers even more.' So, mom called the camp and spoke to the CEO, asking that the camp be made more welcoming to girls" (video). Fortune reported last July that it was the urging of Wojcicki and Facebook COO Sheryl Sandberg that prompted iD Tech Camps — which Wojcicki's and Sandberg's kids had attended — to spin off a girls-only chain of tech camps called Alexa Cafe, which was trialed in the Bay Area in 2014 and expanded to nine locations in 2015. Earlier this month, Fortune noted that Wojcicki's daughter attended the $949-a-week Alexa Cafe summer camp at Palo Alto High, which was coincidentally hosted in the multi-million dollar Media Center (video) that was built thanks to the efforts of Wojcicki's mother Esther (a long-time Paly journalism teacher) and partially furnished and equipped by sister Anne (23andMe CEO) and ex-brother-in-law Sergey Brin's charitable foundation.

An anonymous reader writes: MIT's Mediated Matter Group has published a paper and a video about their new technique for 3D printing with glass. The top part of their printer is a kiln that heats the glass to temperatures of approximately 1900 degrees Fahrenheit, causing it to melt. The molten glass is then passed through an alumina-zircon-silica nozzle, which moves just like an extruder on normal 3D printers. "The frame of the printer is constructed out of 80/20 aluminum stock and square steel tube. They used three independent stepper motors and a lead screw gantry system and drivers which were controlled via an Arduino and a RAMPS 1.4 Arduino shield." The device's makers say, "The tunability enabled by geometrical and optical variation driven by form, transparency and color variation can drive; limit or control light transmission, reflection and refraction, and therefore carries significant implications for all things glass."

We ran video # 1 about Starcoder yesterday and linked to the project's Kickstarter page. At that time, the project had raised $3221 out of a $4000 goal. Today they're up to $5836, which means they've reached their goal and then some, and they still have four days of Kickstarting to go. Nice! It looks like Starcoder will soon be available to a lot more students than are using it now, and that (hopefully) there will be enough server capacity to accommodate students who want to sign up and play on their own, not necessarily with help from their schools.

To learn more about Starcoder, you may want to check out these video clips on Vimeo that not only show you how the game was developed, but give you a look at how it's played. Note: this is video 2 of 2. The transcript covers both videos, plus some material we were forced to edit out of the videos due to length restrictions.)

Starcoder, says the project's Kickstarter page, "is a multiplayer online space action game that teaches kids coding as they play." Their page also points out that it's easier to learn as a group than it is to learn alone. The Starcoder Kickstarter project has collected $3221 at this writing, out of a $4000 goal, and they have until June 17 to come up with the rest. So please take a look at Starcoder, see how it works and why it is unquestionably a more interesting way to learn programming basics than the traditional "highly theoretical and (frankly) boring manner."

Starcoder starts with Blockly. Then, as students advance to higher game levels, moves to JavaScript. Yes, there are levels. Also competitive play, since Starcoder is a massively multiplayer online game. In fact, a big reason for the Kickstarter project is to expand server capability so that kids can play from home, not just in school or during after-school computer classes. One more thing to note: The Win2Learn team behind Starcoders is composed of professional educators and designers. They've been working on STEM education for a while. Want to see some of the thinking behind Starcoder? They have some video clips on Vimeo that not only show you how the game was developed, but give you a good look at how it's played. Does it sound good? Do you want more kids to have access to an ever-improving Starcoder? Then you know what to do. (Note: This is video 1 of 2. The second one will run tomorrow. The transcript covers both videos, plus some material we were forced to edit out of the videos due to length restrictions.)

lpress writes Alibaba is this week's hot news — they have had a lengthy PR campaign (preceded by a documentary film) followed by a record-setting stock offering. After a day of trading Alibaba's market capitalization was comparable to that of established tech giants. But, there are cultural and structural differences between Alibaba and U.S. companies. Alibaba is tightly woven into a complex fabric of personal, corporate and government organization relationships. The same can be said of information technology companies in Singapore. Is owning a share of, say, Apple, conceptually the same as owning a share of Alibaba?

The STEAM Carnival is also available as a traveling event; if you'd like to host it in your town, Two Bit Circus just might be able to accommodate you. (Alternate Video Link)

New submitter Wierzbowski85 (2852925) writes Indie Kickstarter-funded sci-fi short HENRi features classic visual effects and storytelling – with a twist. As detailed in Cinefex magazine (issue 134), the film itself utilizes a mixture of the old and the new — combining live-action sequences with puppetry, quarter-scale miniatures, and modern CGI. Speaking with Wired, the film's director said: "The goal was to seamlessly integrate these different techniques to create the world. My philosophy is that effects are merely a tool to help the story, and that in mind, we used pretty much every trick in the book." The film also stars genre legend Keir Dullea, of 2001: A Space Odyssey. In a making-of video for the film, Dullea says, "Having done 2001, [HENRi] was a wonderful homage to Stanley Kubrick and that film." The short is now available for free viewing online at Hulu.

Wikipedia says, "Ushahidi, Inc. is a non-profit software company that develops free and open-source software (LGPL) for information collection, visualization, and interactive mapping. Ushahidi (Swahili for 'testimony' or 'witness') created a website in the aftermath of Kenya's disputed 2007 presidential election (see 2007–2008 Kenyan crisis) that collected eyewitness reports of violence reported by email and text message and placed them on a Google Maps map." Ushahidi has also been used to map some of the BP oil spill damage in Louisiana and many other events both positive and negative around the globe. This is a mature project, headquarted in Kenya, that recently spun out the BRCK, a "go anywhere, do anything, self-powered, mobile WiFi device," which looks like it would be useful in bringing Internet connectivity to places where the electricity supply is unreliable. || According to Ushahidi, today's interviewee, Rob Baker, "is responsible for overseeing company deliverables and is a lead on communications strategies. Previously, with a 10-year background in software development and with his field experience for aid programs, Rob was a lead for Ushahidi deployments around the world, primarily working in East Africa, the Middle East, and the Caribbean. He’s spoken at the United Nations, World Bank, government, hackathons, and at technical conferences." (Alternate Video Link)

theodp (442580) writes "Among the speakers at last week's National Center for Women & Information Technology (NCWIT) Summit was Chelsea Clinton, who spoke fondly of the Commodore she received as a kid on Christmas Day in 1987. During the Q&A, Clinton was asked (Vimeo), 'What do you see as some of the right policies that could help put Computer Science — which is undeniably the most important 21st Century skill — into our classrooms?' To which the former First Daughter responded, 'I won't quibble with the fact that I think it's very important. I also think other things admittedly are important.' Such as? Aligning Computer Science with Common Core, for one thing ('Ensure that Computer Science is part of the definition of science'). Using state budget surpluses to hire additional physical education teachers for elementary and middle school students, for another ('For Computer Science, as any subject, kids that are well-fed with healthy food and who have been activated in their bodies will able to learn and retain information in any subject better than if they're not'). And, last but not least, 'continuing to tell stories of people that are not...people who don't look like Mark Zuckerberg as successful in Computer Science and technology.' NCWIT, by the way, was listed as a "major partner" on last December's Hour of Code, which arguably made Mark Zuckerberg the face of Computer Science for K-12 students in the nationwide campaign embraced by President Obama during CSEdWeek."

Rambo Tribble (1273454) writes "Popular director Joss Whedon has taken the film world by surprise by releasing his latest offering, 'In Your Eyes', available for download on the same day it premiered at the Tribeca Film Festival. The new release comes from Whedon's own "micro studio", Bellwether Pictures, and is featured on Vimeo as a $5 rental, (free trailer). Whedon mused, 'It's exciting for us because we get to explore yet another new form of distribution — and we get $5.' Mr. Whedon has a history of pushing the delivery envelope, as with Dr. Horrible's Sing-Along Blog, in 2008."

Recently presented at Linuxconf.au was Glyphy, a text renderer implemented using OpenGL ES2 shaders. Current OpenGL applications rasterize text on the CPU using Freetype or a similar library, uploading glyphs to the GPU as textures. This inherently limits quality and flexibility (e.g. rotation, perspective transforms, etc. cause the font hinting to become incorrect and you cannot perform subpixel antialiasing). Glyphy, on the other hand, uploads typeface vectors to the GPU and renders text in real time, performing perspective correct antialiasing. The presentation can be watched or downloaded on Vimeo. The slide sources are in Python, and I generated a PDF of the slides (warning: 15M due to embedded images). Source code is at Google Code (including a demo application), under the Apache License.

An anonymous reader points out The Register's report that Wi-Fi security expert Cédric 'Sid' Blancher has died as the result of a skydiving accident. "Among other things, the 37-year-old Blancher was a sought-after speaker on WiFi security, and in 2005 published a Python-based WiFi traffic injection tool called Wifitap. In 2006, while working for the EADS Corporate Research centre, he also put together a paper on how to exploit Skype to act as a botnet." Some of Blancher's skydiving videos are posted to Vimeo; clearly, it's something he was passionate about.

An anonymous reader writes "Using a Lego Mindstorms set, a Mac, and optical character recognition, Austrian professor Peter Purgathofer created a makeshift ebook copier. From the article: 'It's sort of a combination of high tech meets low. The scanning is done by way of the Mac's iSight camera. The Mindstorms set does two things: Hits the page-advance button on the Kindle (it appears to be an older model, like the one in the picture above), then mashes the space bar on the Mac, causing it to take a picture.' Purgathofer calls the creation a 'reflection on the loss of long established rights.' Check out the Vimeo video for a demonstration."

theodp writes "Bret Victor's The Future of Programming (YouTube video; Vimeo version) should probably be required viewing this fall for all CS majors — and their professors. For his recent DBX Conference talk, Victor took attendees back to the year 1973, donning the uniform of an IBM systems engineer of the times, delivering his presentation on an overhead projector. The '60s and early '70s were a fertile time for CS ideas, reminds Victor, but even more importantly, it was a time of unfettered thinking, unconstrained by programming dogma, authority, and tradition. 'The most dangerous thought that you can have as a creative person is to think that you know what you're doing,' explains Victor. 'Because once you think you know what you're doing you stop looking around for other ways of doing things and you stop being able to see other ways of doing things. You become blind.' He concludes, 'I think you have to say: "We don't know what programming is. We don't know what computing is. We don't even know what a computer is." And once you truly understand that, and once you truly believe that, then you're free, and you can think anything.'"

chicksdaddy writes "Two researchers at the Black Hat Briefings security conference Thursday said Smart TVs from electronics giant Samsung are rife with vulnerabilities in the underlying operating system and Java-based applications. Those vulnerabilities could be used to steal sensitive information on the device owner, or even spy on the television's surroundings using an integrated webcam. Speaking in Las Vegas, Aaron Grattafiori and Josh Yavor, both security engineers at the firm ISEC Partners, described Smart TVs as Linux boxes outfitted with a Webkit-based browser. They demonstrated how vulnerabilities in SmartHub, the Java-based application that is responsible for many of the Smart TV's interactive features, could be exploited by a local or remote attacker to surreptitiously activate and control an embedded webcam on the SmartTV, launch drive-by download attacks and steal local user credentials and those of connected devices, browser history, cache and cookies as well as credentials for the local wireless network. Samsung has issued patches for many of the affected devices and promises more changes in its next version of the Smart TV. This isn't the first time Smart TVs have been shown to be vulnerable. In December, researchers at the firm ReVuln also disclosed a vulnerability in the Smart TV's firmware that could be used to launch remote attacks."

So far, the Rails Girls have groups in cities ranging from Warsaw to Wellington, with U.S. gatherings in Washington D.C., Charlotte NC, San Francisco CA, and... let's make it easy: Here's a map. OMG! They're everywhere! Actually, mostly Europe, being as they started in Finland, same as the Leningrad Cowboys and a popular computer operating system. But they're spreading like mad. Would you believe the reason one of the two founders originally got interested in Ruby on Rails was because she wanted to make a fan page for American politician Al Gore? Our interviewee, Magda (from Rails Girls Warsaw), swears this is true. She also tells us about their upcoming Washington D.C. workshop on June 13th, 2013, in conjunction with the June 14-15 RubyNation event. Sounds like fun, doesn't it. Maybe you need more of this kind of fun where you live, eh? If there isn't a Rails Girls group near you, maybe you should start one and help more women and girls get into programming. This is the Rails Girls' goal. Any particular ages? Not really. And their workshops are all free of charge: "You just need to be excited!"

New submitter Wisdom writes "1bir (1 Block Interactive Raycaster) is a simple ray casting engine implemented only in 254 bytes to run on a stock, unexpanded Commodore 64. The name comes from the fact that on a C64 floppy disk, 1 block is equivalent to 254 bytes stored on a disk sector. In 254 bytes, 1bir sets up the screen for drawing, creates sine and cosine tables for 256 brads based on a simple approximation, casts rays into a 2D map that lives inside the C64 KERNAL ROM, renders the screen in coordination with KERNAL, evaluates 8-way joystick input and detects collision against walls. The ray casting core employs a brute force algorithm to determine visible walls, while the mapping portion supports both open-ended (infinitely looped) and traditional, closed maps. The source code in 6502 assembly is available, with extensive comments. A YouTube video showcases 1bir in a detailed manner with both kind of maps and more information, while a Vimeo video presents a shorter demonstration."

One thing about a Maker Faire is that it brings a delightful number of non-mainstream projects to light that your neighbors have been working on. Scroll down the linked page above to see some samples of what came out of the woodwork at the latest Austin version. A Jedi Starfighter under construction.... a very strange little boat... and down at the bottom of the page we see The Type 40 Mark III Console, an "interactive sound sculpture" that redefines the term "bells and whistles" in a whole new way that pleases children and adults alike as they twist knobs and punch buttons, and things happen (or don't happen). It really does look just like a Tardis control console. Even project co-creator and spokesbeing Steve Noreyko says so, and he's the one who got in front of Timothy Lord's camcorder in an unfortunately noisy room. But there he was, with das blinkenlights behind him delighting and amazing a happily bemused crowd, just as Steve and his crew have amazed crowds at Art Outside, Burning Flipside, and other local festivals.

An anonymous reader tipped us to news of an interesting hack for the Oculus Rift: a simulation of being beheaded by a Guillotine. Thrown together in a couple of days at the Exile Code Jam, the simulation lets you... "look around to see the blade above, the crowd of onlookers around them, and the executioner who signals the blade be dropped. It also enhances the experience when someone watches the blade falling on a nearby screen and taps the user on the back of the neck at the time of impact." Just a bit morbid. There's a video of people "playing" (nsfw language in a few reactions to being virtually beheaded).

Hmmm...changing diapers or cleaning up code — both are messy, but one smells less."

Once upon a time, people shot a kind of video called "film." And one of the most popular film camera makers was Bolex. Their 16 mm and Super 16 mm cameras were the favored tools for indie film makers, low budget TV news operations, and film schools. Sure, there were 8mm and Super 8, but they didn't give you the stunning clarity you could get with 16 mm. Besides that, carrying a Bolex was kind of like telling everyone, "Look at me! I'm a professional moviemaker!" And with the cost of processing 16 mm film back in the late 1960s and early 1970s you pretty much had to be a pro -- or at least have access to a TV station or college film lab if you wanted to do any serious movie experimentation. Obviously, times have changed. You can now buy a fairly serious camcorder at a consumer-level price. Or a DSLR that can do video -- and do depth of field tricks hardly any camcorder can match. Even so, if you are a film junkie, you just might want a Digital Bolex. Thanks to a highly successful Kickstarter campaign, it looks like you might be able to buy one before long. Too bad you can't still get Kodachrome film, which was the perfect film for your Bolex. Ah, well. RAW format digital is more or less the 21st Century equivalent of Kodachrome, so it will have to do.

Wescotte writes "The Amateur Monster Movie is the first feature length film by King's Tower Productions and writer/director Kyle Richards, all filmed within an hour of Milwaukee, WI over the course of 57 days during the summers of 2009 and 2010. It was shot as a 'no-budget' film and the entire cast and crew worked for free on owned or borrowed equipment. After a few film festival appearances, highlighted by the Wisconsin Film Festival, and — a cast and crew favorite — the Oshkosh Horror Film Festival, Richards decided to release the film for free online, a move intended to encourage more movies and media to do the same and allow free media access to everyone online. The film can be streamed from Vimeo and YouTube or downloaded via torrent at Pirate Bay, KAT, and magnet link. More information and production stills can be found at the Facebook Page, and IMDB." The acting is straightforwardly campy, but (promise or warning) the gory, zero-budget special effects start about four minutes in.

unts writes "Taking DRM further than it's gone before, a group of designers have built a DRM'd chair that will melt its own joints and destroy itself after 8 uses. The chair uses an Arduino and sensors to monitor the number of uses, then triggers the melting of a set of joints that hold it together, making the product unusable without some carpentry skills. The video of device at work is both amusing and a little disconcerting."

Wired writes: 'If it sounds a little bit like 2001: The Later Years, then here's the real twist: HENRi, the ship/body, is voiced [by] Dr. Dave Bowman himself, Keir Dullea.' In a making-of video for the film, Dullea says, 'I guess you could say the character of HENRi was a sane version of HAL.' The film itself utilizes a mixture of the old and the new — combining live-action sequences with puppetry, quarter-scale miniatures, and modern CGI. The official trailer has just been released."

After an alcohol induced blackout motivated a bit of introspection (video), Dhairya Dand pulled together a coin cell battery, an ATtiny microcontroller, and an IR transceiver molded into gelatin to create self-aware glowing ice-cubes. The cubes glow and beat to the ambient music, but more importantly, they know how fast and how much you are drinking, and they change color from green to orange to finally red as you reach your safe limit. If things go too far, the ice cubes can connect to your smartphone and send a text message for a friend come get you. Of course, you have to remember not to swallow them."

This video is an interview with Matt Heusser, who makes a good living as an independent IT consultant. He says many other people who are currently pounding out code or performing other routine computer-oriented tasks can become independent, too. He's not selling a course or anything here, just passing on some advice to fellow Slashdot readers. He's written up some of this advice in a series of four articles: Getting People to Throw Money At You; How to become IT Talent; That Last Step to Become ‘Talent’ In IT; and The Schwan’s Solution. He also gave a speech last November titled Building your reputation through creative disobedience. (The link is to a 50 minute video of that speech.) Anyway, we figure quite a few Slashdot readers are at least as smart as Matt and may want to take some career steps similar to the ones he has taken. In today's video, he gives you some ideas about how to stop being an IT worker and how to become IT talent instead.

mpol writes "The job market can be hard right now, depending on your background and location. Having a disability makes things even more interesting. Seven years ago I suffered from a psychosis, and I was diagnosed with schizophrenia. I have been recovering quite well, and last year I started searching for a paying job. I found one, but it didn't turn out to be the right place, so I'm back at my volunteer job as web developer. My current workplace is quite unique, as there are several people who have had a psychosis in the past, or have been diagnosed with autism. When I look at myself I know that I have some things that will always play a role: I'm very sensitive to the atmosphere in the workplace for example. I also need clear communication, more so than other people. Furthermore, a workweek of maybe 20-25 hours is the max for me. I tried self-employment, but motivation and discipline are a bit hard to come by, and it's not something that will work for me long-term. In theory it's perfect, in practice not so much. I'm not sure what my short-term future will look like, and for this year I'm quite happy where I am, but next year I might go searching for a salaried job again. I'm wondering if there are more people on Slashdot who have a job in ICT, or are seeking one, and also have disabilities. How did you land at your job, and what issues do you run into in daily practice?"

For years, the U.S. has been hemorrhaging manufacturing jobs to China because of the vastly cheaper labor pool. But now, several different technologies have ripened to the point where U.S. companies are bringing some operations back home. 3D printing, robotics, AI, and nanotechnology are all expected to dramatically change the manufacturing landscape over the next several years. From the article: "The factory assembly that the Chinese are performing is child’s play for the next generation of robots—which will soon become cheaper than human labor. Indeed, one of China’s largest manufacturers, Taiwan-based Foxconn Technology Group, announced last August that it plans to install one million robots within three years to do the work that its workers in China presently do. It found Chinese labor to be too expensive and demanding. The world’s most advanced car, the Tesla Roadster, is also being manufactured in Silicon Valley, which is one of the most expensive places in the country. Tesla can afford this because it is using robots to do the assembly. ... 3D printers can already create physical mechanical devices, medical implants, jewelry, and even clothing. The cheapest 3D printers, which print rudimentary objects, currently sell for between $500 and $1000. Soon, we will have printers for this price that can print toys and household goods. By the end of this decade, we will see 3D printers doing the small-scale production of previously labor-intensive crafts and goods. It is entirely conceivable that in the next decade we start 3D-printing buildings and electronics."

In a world increasingly dominated by the cloud, privacy is often sacrificed for convenience. Imagine a world where you could use cloud services without allowing the provider to read your data. Author of Cryptocat (a browser-based secure chat system) Nadim Kobeissi shared the problems he faced developing Cryptocat, his solutions, and future of client-side cryptography. Read on for more.

Update: 07/18 03:48 GMT by U L : Slides (PDF) from and video of the talk are now online.

Despite giving workshops on Off- the-Record messaging to Middle Eastern Activists, Kobeissi found that adoption was low because of the complexity of installing new chat software, plugins, generating keys, verifying your friends, etc. Especially when the person on the other end had not been taught how to use OTR. At the end of the talk he gave some reasons why North American users may find it easier: we develop this software and export it so we have a community of developers available for support, whereas in the Middle East this is foreign software lacking context.

Since he was interested in client-side cryptography and there was a clear problem getting people to securely communicate, he set out to experiment with the former while solving the latter. He identified several problems thwarting success:

• Code delivery is insecure (will it be intercepted and modified? Can you trust the original server?). Compounding this, code in browsers is ephemeral, making it nigh impossible to trust.
• The JavaScript random number generator, while fine for most uses, is not good enough for encryption (its only seed is the current time, making it vulnerable to attack).
• There are no standardized primitives for working with cryptography algorithms in JavaScript, and libraries available at the time were not very good.
• Browser sandboxing was often incomplete and exploitable (a situation which has improved, but new bugs are still occasionally found). If the sandbox breaks, all bets are off.

To each problem there is a solution. For code delivery, Chrome apps proved ideal. There are interesting client side security features, bundles can be signed, sandboxing is effective (aside from the occasional convoluted exploit), and you only have to verify the source once. For encryption, he developed his own implementation of the Fortuna CSPRNG and several cryptography primitives in JavaScript, using keypress timing, mouse movement, window position, etc. for entropy (on mobile devices, the accelerometer has proven useful). Chrome later added their own implementation (which has access to the system entropy source) with Firefox support coming soon.

But where to go from here?

We need an API for transparent encryption: it should be as enforceable and easy as https. We need a full crypto toolkit in the browser, protected key storage (the author suggested protected JavaScript variables), OpenSSL compatibility (certificate formats, not the horrendous C API). And we need secure communications usable by mere mortals.

The W3C formed a web cryptography working group six months ago, with a specification due in 18 months.

Working with the Guardian project, the Cryptocat developers hope to introduce AweSoMe (always secure messaging), which aims to build a suite of utilities for easy and secure messaging (guaranteed message delivery, verifiable end-to-end encryption, and control over logging).

Development of Cryptocat2 is in progress, using XMPP rather than their experimental protocol, and mpOTR which extends OTR with group chat features and newer ciphers. The specification is half complete, and contributions were encouraged.

Although secure chat for the masses is being worked on, there is still much work to be done on securely storing data in the cloud. Luckily, the lessons learned developing Cryptocat will apply to future projects.

Similar to his questions on PBS' Scientific American Frontiers, actor Alan Alda wrote to the journal Science with a proposition called The Flame Challenge (PDF). Contestants would have to explain a flame to an eleven-year-old kid, and the entries would be judged by thousands of children across the country. The winner of The Flame Challenge is quantum physics grad student Ben Ames, whose animated video covers concepts like pyrolysis, chemiluminescence, oxidation and incandescence boiled into a humorous video, complete with song. Now they are asking children age 10-12 to suggest the next question for the Flame Challenge. Kids out there, what would you like scientists to explain?"

It can resume users' sessions after being disconnected, and supports both client and server-side session recording/playback (view as a log or like a video). Gate One can also be embedded into other web-based applications such as administration interfaces, serial port concentrators, virtual appliances, or whatever."

John Cowan recently gave a talk on the progress of R7RS (slides), the next revision of the Scheme language standard, at LispNYC. After the R6RS debacle, the community stepped back and is now basing the next standard on R5RS; the work has been split into two languages — R7RS-Small and R7RS-Large. The first working group is preparing to issue a final draft of the R7RS-Small language (PDF; clocking in at 73 pages vs. R5RS's 50) within the next few weeks. Read on for a summary of the planned changes to R7RS (more or less in the order of presentation). The talk details a number of improvements over R5RS and R6RS, and is divided into two portions. The majority of the talk discuses the status of the small language, with the last portion giving a quick update on the future intent of the large language group.

First on the list of major new features is a mandatory library system designed to be easily implemented atop existing module systems. R6RS's library system proved to tackle too much at once and be incompatible with everything already in a use (a persistent concern in the design of the R7RS-Small language). The R7RS system, on the other hand, is static, simple, and just powerful enough to promote implementation of portable libraries.

Exceptions are stripped down from R6RS (which proved too incompatible with existing implementations for practical use). guard (similar to try...catch in other languages) and with-exception-handler are supported: the latter runs the handler in the context from which the error was triggered (permitting recovery from the error like invoke-restart ) Unlike r6rs, exceptions lack a strictly defined hierarchy and can be any object (you could e.g. throw 4 if you really felt like it).

Dynamically scoped variables, in the form of parameters, are now part of the standard. Unlike Common Lisp special variables, parameters are first-class objects bound to expressions rather than symbols that are declared dynamically scoped. For reasons of simplicity it was decided to make parameters immutable (i.e. any "mutation" has to be done by rebinding). This has the (intentional) side-effect of making parameters play more nicely with threads (when mutation is permitted, setting a parameter that has not been rebound in the current thread requires synchronizing all threads and can have unexpected results).

As expected, R7RS includes bytevectors to complement strings. The small language standard only permits accessing bytevectors as ordered sets of unsigned 8-bit values (the large language standard will offer more flexible access). Binary I/O is implemented via a set of parallel procedures (open-binary-input-file vs. open-input-file, etc.) in contrast to the incredibly complicated dual binary/text ports provided by R6RS. Additionally, string and bytevector ports similar to SRFI-6 are provided instead of the incompatible string ports provided by R6RS.

Taylor Campbell noted that integer division in most languages is insufficiently expressive, and so R7RS will provide Euclidean division and centered division in addition to the usual suspects. Mathematicians rejoice!

As with R6RS, Unicode support is mandated. Unlike R6RS, the only characters that must be supported are those present in ASCII. For supported characters, Unicode case mapping and normalization are mandatory. One interesting diversion from Unicode and R6RS is that string order comparison is implementation-dependent: this gives implementers latitude with the internal encoding of strings.

Any user of Scheme knows that the language strives for consistent and obvious names for bindings. R7RS furthers this goal by resolving the long-standing inconsistency with core data structure creation, copying, mutation, mapping, etc. Lists, strings, and vectors now have a consistent set of each: make-TYPE, TYPE-copy, TYPE-set!, etc. Conversion procedures between all three types are also provided.

Finally, number of minor improvements were made. Most notable: record types are compatible with SRFI-6 (widely in use today); case sensitivity is the default (with optional insensitivity via include-ci); s-expression and nested block comments were added; IEEE infinities and NaNs have read syntax; strings may contain C-style escape sequences; Common Lisp circular list notation is supported; and common extensions to syntax-rules were standardized.

The final 20 minutes of the talk were about the status of R7RS-Large.

The R7RS Large language is currently on hold, mostly because all the small language members are on the large language committee as well, so there is a lack of time to work on both simultaneously. Work is planned to resume upon release of the final draft of the small language. Some work, however, has been completed.

The main focus of R7RS-Large is providing Scheme "with batteries included." John Cowan started the process by looking beyond the Lisp and Scheme communities (Python is mentioned) to figure out which libraries modern programmers expect their language to include.

This resulted in a list of around 250 packages that was narrowed down to around 80 packages through an initial voting process. It was decided then than some desirable packages (e.g. a foreign function interface) had to be omitted due to complexity. It is expected that implementers will continue experimenting and gradually come to a consensus on the larger packages using the existing SRFI process, and perhaps another revision of the standard down the road.

Of the packages planned for inclusion, the most prominent are: networking, threads, regular expressions, delimited continuations, URI handling, date and time parsing/arithmetic/formatting, hash tables, ambient environment access, file system directory access, gettext (i18n support), and pattern matching.

Most will be optional; packages will only be made mandatory if a number of the other packages require them. A compliant R7RS-Large implementation will only have to either provide a package fully or not at all (half implementations are forbidden).

Interestingly, R7RS large with all packages will be even larger than Common Lisp.

To avoid getting bogged down in stylistic discussions, a decision was made to focus on functionality above other concerns. The resulting packages may not be aesthetically pleasing to everyone, but will provide useful functionality. Users who disagree with naming, scope of functionality, argument ordering, etc. will be free to use the library system to import only the bindings they want, rename functions, wrap things into the style they want, etc. Basically, a compromise between the MIT approach and "Worse is Better" is being sought.

Here a call for volunteers is made: Since the focus will be on functionality over pure aesthetics, developers outside of the Lisp and Scheme communities are actively encouraged to participate in the R7RS-Large language process. No fixed time commitment would be required; the goal is to get a lot of people involved with a few core members maintaining momentum and guiding the process. The R7RS-Large language is most definitely a language designed by and for developers. So, make your voice heard!

Overall R7RS is shaping up to be the standard R6RS should have been (which, of course, could not have happened without the lessons of R6RS). The split between an elegant core language with each design issue meticulously fretted over and voted upon and a looser library standard should, hopefully, result in a core language that will stand the test of time with a standard library that can be used to get actual work done.

mikejuk writes with a light piece in I Programmer about a neat Kinect and gigantic projector hack. From the article: "If you remember Breakout — rows of blocks a the top of the screen and a paddle to bounce a ball into them to destroy a block — then you might not feel nostalgic about it. After all, it was a very limited sort of game. However, take one Kinect and one building and you have something quite different when you use it to create a Breakout game. The bricks, ball and paddle all projected onto an old building and the player moves from side-to-side to control the paddle. The player's position is being detected by a Kinect, is there no end to the fun you can have with this gadget. The really clever bit, and you might not notice it unless you look closely at the video, is that the ball bounces off real architectural features of the building — like the windows, for example."

rsk points out this "review of the $1200 Makerbot Thing-o-Matic 3D printer. After a 16-hour self-assembly and a few weeks of use, a blown PSU was replaced with a higher powered PSU via a mod to the Thing-o-Matic. Video of the Thing-o-Matic printing out little solar panel mounts from Google Sketch-up included in the review. Final thoughts suggest that the Thing-o-Matic is not a great gift for non-engineers: 'You need a decent understanding of robotics, hardware, software, electronics and mechanics, need a little hand dexterity and a ton of patience.'"
