The National Science Foundation is developing a way to create working code using "automated program synthesis," a new technology called ExCAPE "that provides human operators with automated assistance.... By removing the need for would-be programmers to learn esoteric programming languages, the method has the potential to significantly expand the number of people engaged in programming in a variety of disciplines, from personalized education to robotics." Rajeev Alur, who leads a team of researchers from America's nine top computer science programs, says that currently software development "remains a tedious and error-prone activity."

While its lofty goals of broadly remaking the art of programming might not be realized, the research has already made some advances and resulted in several tools already in use in areas such as commercial software production and education...
For example, the NSF created a new tool (which they've recently patented) called NetEgg, which generates code for controlling software-defined networks, as well as Automata Tutor and AutoProf, which provide automated feedback to computer science students.Read Replies (0)

Random web surfers could send a text message or even upload an image to be displayed on the back glass of Mark Lachniet's pinball machine, according to Mael517, while the machine itself webcast footage of both its playing field and backglass using Twitch. Interestingly, all the extra functionality was coded directly into the machine, according to Lachniet, who added only the webcam and an ethernet cord. The Hobbit [machine] has a whole bunch of hardware that I don't really understand and can barely fix... However, it has a computer in its guts, and this I can mostly understand. After identifying the pinball machine's motherboard, CPU, operating system (Ubuntu) and an SQL database, Lachniet was able to backup its software, and then create his own modifications. He envisions more possibilities -- for example, the ability to announce high scores on social media accounts or allow remote servicing of the machine. Lachniet even sees the possibility of a world-wide registry of pinball game scores with each player's location overlaid on Google Maps "so you could view pinball hot spots and where the high scores were coming from," and maybe even networking machines together to allow real-time global competition."Read Replies (0)

An anonymous Slashdot reader writes:
Hacking researchers have uncovered a new attack technique which can alter the memory of virtual machines in the cloud. The team, based at Vrije Universiteit, Amsterdam, introduced the attack, dubbed Flip Feng Shui (FFS)...and explained that hackers could use the technique to crack the keys of secured VMs or install malicious code without it being noticed...
Using FFS, the attacker rents a VM on the same host as their chosen victim. They then write a memory page which they know exists on the vulnerable memory location and let it de-duplicate. The identical pages, with the same information, will merge in order to save capacity and be stored in the same part of memory of the physical computer. This allows the hacker to change information in the general memory of the computer.
The researchers demonstrated two attacks on Debian and Ubuntu systems -- flipping a bit to change a victim's RSA public key, and installing a software package infected with malware by altering a URL used by apt-get. "Debian, Ubuntu and other companies involved in the research were notified before the paper was published, and have all responded to the issue."Read Replies (0)

Saturday a SpaceX rocket completed the company's fourth successful landing at sea (watched by over 100,000 viewers on YouTube and Flickr). Saturday's landing means Elon Musk's company has now recovered more than half the rockets they've launched. An anonymous Slashdot reader quotes Saturday's report from The Verge:
Tonight's landing was particularly challenging for SpaceX... The Falcon 9 had to carry its onboard satellite -- called JCSAT-16 -- into...a highly elliptical orbit that takes the satellite 20,000 miles out beyond Earth's surface. Getting to GTO requires a lot of speed and uses up a lot of fuel during take off, more so than getting to lower Earth orbit. That makes things difficult for the rocket landing afterward...there's less fuel leftover for the vehicle to reignite its engines and perform the necessary landing maneuvers.
CEO Elon Musk said the company is aiming to launch its first landed rocket sometime this fall...SpaceX's president, Gwynne Shotwell, estimates that reusing these landed Falcon 9 vehicles will lead to a 30 percent reduction in launch costs.
SpaceX named their drone ship "Of Course I Still Love You."Read Replies (0)

"The world's next energy revolution is probably no more than five or ten years away," reports The Telegraph. "Cutting-edge research into cheap and clean forms of electricity storage is moving so fast that we may never again need to build 20th Century power plants in this country..." Slashdot reader mdsolar quotes their article:
The US Energy Department is funding 75 projects developing electricity storage, mobilizing teams of scientists at Harvard, MIT, Stanford, and the elite Lawrence Livermore and Oak Ridge labs in a bid for what it calls the "Holy Grail" of energy policy. You can track what they are doing at the Advanced Research Projects Agency-Energy (ARPA-E). There are plans for hydrogen bromide, or zinc-air batteries, or storage in molten glass, or next-generation flywheels, many claiming "drastic improvements" that can slash storage costs by 80pc to 90pc and reach the magical figure of $100 per kilowatt hour in relatively short order. "Storage is a huge deal," says Ernest Moniz, the U,S. Energy Secretary and himself a nuclear physicist. He is now confident that the U.S. grid and power system will be completely "decarbonized" by the middle of the century.
One energy consultant predicts the energy storage market will be worth $90 billion in 2025 -- 100 times larger than it is today.Read Replies (0)

Long-time Slashdot reader chicksdaddy quotes a report from Security Ledger:
One of every five software vulnerabilities discovered in vehicles in the last three years are rated "critical" and are unlikely to be resolved through after the fact security fixes, according to an analysis by the firm IOActive. "These are the high priority 'hair on fire' vulnerabilities that are easily discovered and exploited and can cause major impacts to the system or component," the firm said in its report...
The bulk of vulnerabilities that were identified stemmed from a failure by automakers and suppliers to follow security best practices including designing in security or applying secure development lifecycle (SDL) practices to software creation... The result is that vehicle cybersecurity vulnerabilities are not solvable using "bolt-on" solutions, IOActive concluded...
The article argues we're years away from standards or regulations, while describing auto-makers as "wedded to the notion that keeping the details of their systems secret will ensure security."Read Replies (0)

An anonymous reader writes: Tim Gihring at MinnPost talks to the creators of what was, briefly, the biggest thing in the internet, Gopher. Gopher, for those who don't know or have forgotten, was the original linked internet application, allowing you to change pages and servers easily, though a hierarchical menu system. It was quick, it was easy to use, and important for this day and age, it didn't have Flash.
The article remembers Tim Berners-Lee describing the idea of a worldwide web at a mid-March, 1992 meeting of the Internet Engineering Task Force, at a time when Gopher "was like the Web but more straightforward, and it was already working."
Gopher became magnitudes more popular -- both MTV and the White House announced Gopher sites -- leading to GopherCons around the country. Just curious -- how many Slashdot readers today remember using Gopher?Read Replies (0)

He grew up in San Jose, and at the age of 25 sold his second online advertising company to Yahoo for $300 million just nine years ago. Friday Gurbaksh Chahal was sentenced to one year in jail for violating his probation on 47 felony charges from 2013, according to an article in The Guardian submitted by an anonymous Slashdot reader:
Police officials said that a 30-minute security camera video they obtained showed the entrepreneur hitting and kicking his then girlfriend 117 times and attempting to suffocate her inside his $7 million San Francisco penthouse. Chahal's lawyers, however, claimed that police had illegally seized the video, and a judge ruled that the footage was inadmissible despite prosecutors' argument that officers didn't have time to secure a warrant out of fear that the tech executive would erase the footage.
Without the video, most of the charges were dropped, and Chahal, 34, pleaded guilty to two misdemeanor battery charges of domestic violence... In Silicon Valley, critics have argued that Chahal's case and the lack of serious consequences he faced highlight the way in which privileged and wealthy businessmen can get away with serious misconduct.. On September 17, 2014, prosecutors say he attacked another woman in his home, leading to another arrest. Friday Chahal was released on bail while his lawyer appeals the one-year jail sentence for violating his probation.Read Replies (0)

An anonymous Slashdot reader quotes a report from CBS News:
For the hackers at Symantec Security Response, Election Day results could be manipulated by an affordable device you can find online. "I can insert it, and then it resets the card, and now I'm able to vote again," said Brian Varner, a principle researcher at Symantec, demonstrating the device...
Symantec Security Response director Kevin Haley said elections can also be hacked by breaking into the machines after the votes are collected. "The results go from that machine into a piece of electronics that takes it to the central counting place," Haley said. "That data is not encrypted and that's vulnerable for manipulation."
40 states are using a voting technology that's at least 10 years old, according to the article. And while one of America's national election official argues that "there are paper trails everywhere," CBS reports that only 60% of states conduct routine audits of their paper trails, while "not all states even have paper records, like in some parts of swing states Virginia and Pennsylvania, which experts say could be devastating."Read Replies (0)

Internet services "have come under attack in recent years in the form of identity and intellectual property theft, deliberate and unintentional service disruption, and stolen data," writes NIST. "Steps must be taken to enhance existing efforts to increase the protection and resilience of the digital ecosystem, while maintaining a cyber environment that encourages efficiency, innovation, and economic prosperity." Separately, NIST is also requesting comments on a new process to "solicit, evaluate, and standardize one or more quantum-resistant public-key cryptographic algorithms... If large-scale quantum computers are ever built, they will be able to break many of the public-key cryptosystems currently in use. This would seriously compromise the confidentiality and integrity of digital communications on the Internet and elsewhere...

Long-time Slashdot reader sehlat shares "a highly accessible summary" of a new theory about why we haven't yet find life on other planets -- that "we're not latecomers, but very, very early." From Lab News:
The universe is 13.8 billion years old, with Earth forming less than five billion years ago. One school of thought among scientists is that there is life billions of years older than us in space. But this recent study in the Journal of Cosmology and Astroparticle Physics argues otherwise... "We find that the chance of life grows much higher in the distant future..."
Stars larger than approximately three times the Sun's mass will perish before life has a chance to evolve... The smallest stars weigh less than a tenth as much as the sun and will glow for 10 trillion years, meaning life has lot of time to begin on those planets orbiting them in the 'habitable zone'. The probability of life increases over time so the chance of life is many times higher in the distant future than now.
The paper ultimately concludes that life "is most likely to exist near 0.1 solar-mass stars ten trillion years from now."Read Replies (0)

GoldenEye: Source received its first update in more than three years this week. It's free to download and it features 25 recreated maps, 10 different multiplayer modes, and redesigned versions of the original game's 28 weapons. It was created using Valve's Source engine, the same set of tools used to create Counter Strike and Half-Life games. So it's a massive step up in both visuals and performance for one of the more drastically dated gaming masterpieces of the last 20 years...
GoldenEye 007, the beloved N64 first-person shooter, has been recreated in high-definition glory by a team of dedicated fans over the course of 10 years...the attention to detail and the amount of effort that went into GoldenEye: Source make it one of the most polished HD remakes of a N64 classic.
With 8 million copies sold, Wikipedia calls it the third best-selling Nintendo 64 game of all-time (although this version doesn't recreate its single-player campaigns). Anyone have fond memories of playing Goldeneye 007?Read Replies (0)
