Engineers Are Leaving America For Canada (bloomberg.com)
An anonymous reader shares an excerpt from a report via Bloomberg: The H-1B was created in 1990, part of an immigration overhaul signed into law by President George H.W. Bush that also created the EB-5 investor visa -- the subject of a fracas involving Kushner Cos. seeking Chinese investment -- and the diversity lottery, which Trump has attacked. Today, an estimated half a million H-1B holders live in the U.S. No one tracks exactly how many ditch their skilled visas for the permanent residency Canada offers, but during the first year of Trump's presidency, the number of tech professionals globally who got permanent residency in Canada ticked up almost 40 percent from 2016, to more than 11,000.
In 1967, Canada became the first country to adopt a points-based immigration system. The country regularly tweaks how it rates applicants based on national goals and research into what makes for successful integration: A job offer used to come with 600 points, but now it's worth just 200. Other factors like speaking fluent English or French -- or, even better, both -- have been given more weight over the years. Country of origin is irrelevant. In 2016, Canada increased national immigration levels to 300,000 new permanent residents annually. Last year, in consultation with trade groups, it created a program called the Global Skills Strategy to issue temporary work permits to people with job offers in certain categories, including senior software engineers, in as little as two weeks. Since the program started in June, more than 5,600 people have been granted permits, from the U.S., India, Pakistan, Brazil, and elsewhere. -
Millions Of Waze Users Can Have Their Movements Tracked By Hackers (fusion.net)
An anonymous reader quotes a report from Fusion: Researchers at the University of California-Santa Barbara recently discovered a Waze vulnerability that allowed them to create thousands of "ghost drivers" that can monitor the drivers around them -- an exploit that could be used to track Waze users in real-time. Here's how the exploit works. Waze's servers communicate with phones using an SSL encrypted connection, a security precaution meant to ensure that Waze's computers are really talking to a Waze app on someone's smartphone. Zhao and his graduate students discovered they could intercept that communication by getting the phone to accept their own computer as a go-between in the connection. Once in between the phone and the Waze servers, they could reverse-engineer the Waze protocol, learning the language that the Waze app uses to talk to Waze's back-end app servers. With that knowledge in hand, the team was able to write a program that issued commands directly to Waze servers, allowing the researchers to populate the Waze system with thousands of "ghost cars" -- cars that could cause a fake traffic jam or, because Waze is a social app where drivers broadcast their locations, monitor all the drivers around them. You can read the full paper detailing the researchers' findings here. Is there a solution to not being tracked? Yes. If you're a Waze user, you can set the app to invisible mode. However, Waze turns off invisible mode every time you restart the app so beware. -
Sorry, But Lasers Aren't Taking You To Mars Anytime Soon
An anonymous reader writes: It's long been a dream of humanity to travel interplanetary distances at great speeds, or to make it to another star system within a human lifetime. Until recently, technologies to get us there — antimatter propulsion, wormholes or warp drive — have all been composed of physically unrealistic solutions. But recent developments in laser technology make directed energy propulsion a feasible solution. By building a giant laser array in space and developing a new type of solar sail that reflects the laser light with incredible efficiency, a laser sail, this propulsion system is scalable to arbitrarily large powers. There are many technical obstacles to be overcome, and so it's unlikely we'll see the fruit of this anytime in the next few decades (despite the promises of some), but this may well be the technology that takes us to the stars in the coming centuries. -
Brain Imaging Shows Abnormal White Matter Areas In the Brains of Stutterers
n01 writes: Stuttering — a speech disorder in which sounds, syllables or words are repeated or prolonged — affects more than 70 million people, or about 1% of the population, worldwide. Once treated as a psychological or emotional condition, stuttering can now be traced to brain neuroanatomy and physiology. Two new studies from UC Santa Barbara researchers provide insight into the treatment of the speech disorder as well as understanding its physiological basis. The first paper, published in the American Journal of Speech-Language Pathology, finds that the MPI stuttering treatment program, a new treatment developed at UCSB, was twice as effective as the standard best practices protocol. The second study, which appears in the Journal of Speech, Language, and Hearing Research, uses diffusion spectrum imaging (DSI) in an MRI scanner to identify abnormal areas of white matter in the brains of adult stutterers. According to co-author Janis Ingham, a professor emerita of speech and hearing sciences at UCSB and co-author of both papers, the two studies taken together demonstrate two critical points: A neuroanatomic abnormality exists in the brains of people who stutter, yet they can learn to speak fluently in spite of it. -
Location of Spilled Oil From 2010 Deepwater Horizon Event Found
Chipmunk100 writes: A study published in the journal Proceedings of the National Academy of Sciences (abstract) claims to have identified the location of two million barrels of submerged oil thought to be trapped in the deep ocean following the 2010 Deepwater Horizon spill. By analyzing data from more than 3,000 samples collected at 534 locations over 12 expeditions, they identified a 1,250-square-mile patch of the deep sea floor upon which 2 to 16 percent of the discharged oil was deposited. The fallout of oil to the sea floor created thin deposits most intensive to the southwest of the Macondo well. The oil was most concentrated within the top half inch of the sea floor and was patchy even at the scale of a few feet." -
Google To Build Quantum Information Processors
An anonymous reader writes The Google Quantum AI Team has announced that they're bringing in a team from the University of California at Santa Barbara to build quantum information processors within the company. "With an integrated hardware group the Quantum AI team will now be able to implement and test new designs for quantum optimization and inference processors based on recent theoretical insights as well as our learnings from the D-Wave quantum annealing architecture." Google will continue to work with D-Wave, but the UC Santa Barbara group brings its own areas of expertise with superconducting qubit arrays. -
Jimmy Carter Calls Snowden Leak Ultimately "Beneficial"
eldavojohn writes "According to RT, the 39th president of the United States made several statements worth noting at a meeting in Atlanta. Carter said that 'America has no functioning democracy at this moment' and 'the invasion of human rights and American privacy has gone too far.' The second comment sounded like Carter predicted the future would look favorably upon Snowden's leaks — at least those concerning domestic spying in the United States — as he said: 'I think that the secrecy that has been surrounding this invasion of privacy has been excessive, so I think that the bringing of it to the public notice has probably been, in the long term, beneficial.' It may be worth noting that, stemming from Zurcher v. Stanford Daily, Jimmy Carter signed the Privacy Protection Act of 1980 into law and that Snowden has received at least one nomination for the Nobel Peace Prize." -
Cause of LED Efficiency Droop Finally Revealed
An anonymous reader writes "Researchers from the University of California, Santa Barbara, in collaboration with colleagues at the École Polytechnique in France, have been able to prove the theory behind LED 'droop.' LED droop is the term for how LEDs emit less light when the amount of current being pushed through them goes above a certain level. 'The cost per lumen of LEDs has held the technology back as a viable replacement for incandescent bulbs for all-purpose commercial and residential lighting.' Now that we understand what causes this, we should start to see research go into technology to circumvent LED Droop. 'LEDs have enormous potential for providing long-lived high quality efficient sources of lighting for residential and commercial applications. The U.S. Department of Energy recently estimated that the widespread replacement of incandescent and fluorescent lights by LEDs in the U.S. could save electricity equal to the total output of fifty 1 GW power plants.'" A pre-print of the team's paper is available at the arXiv. -
How Would an Astronaut Falling Into a Black Hole Die?
ananyo writes "According to the accepted account, an astronaut falling into a black hole would be ripped apart, and his remnants crushed as they plunged into the black hole's infinitely dense core. Calculations by Joseph Polchinski, a string theorist at the Kavli Institute for Theoretical Physics in Santa Barbara, California, though, point to a different end: quantum effects turn the event horizon into a seething maelstrom of particles and anyone who fell in would hit a wall of fire and be burned to a crisp in an instant. There's one problem with the firewall theory. If Polchinski is right, then either general relativity or quantum mechanics is wrong and his work has triggered a mini-crisis in theoretical physics." -
California Professors Unveil Proposal To Attack Asteroids With Lasers
An anonymous reader writes "Yesterday's twin events with invading rocks from outer space — the close encounter with asteroid 2012 DA14, and the killer meteorite over Russia that was more than close — have brought the topic of defending mankind against killer asteroids back into the news. The Economist summarizes some of the ideas that have been bandied about, in a story that suggests Paul Simon's seventies hit "Fifty Ways to Leave Your Lover": Just push it aside, Clyde. Show it the nuke, Luke. Gravity tug, Doug. The new proposal is an earth orbiting, solar-powered array of laser guns called DE-STAR (Directed Energy Solar Targeting of AsteRoids) from two California-based professors, physicist Philip Lubin (UCSB) and industrial statistician Gary Hughes (Cal Polytechnic State). Lubin and Hughes say their system could be developed and deployed in a range of sizes depending on the size of the target: DE-STAR 2, about the size of the International Space Station (100 meters) could nudge comets and asteroids from their orbits, while DE-STAR 4 (100 times larger than ISS) could evaporate an asteroid 500 meters in diameter (10 times larger than 2012 DA14) in a year. Of course, this assumes that the critters could be spotted early enough for the lasers to do their work." -
Russian Meteor Largest In a Century
gbrumfiel writes "A meteor that exploded over Russia's Chelyabinsk region this morning was the largest recorded object to strike the earth in more than a century, Nature reports. Infrasound data collected by a network designed to watch for nuclear weapons testing suggests that today's blast released hundreds of kilotons of energy. That would make it far more powerful than the nuclear weapon tested by North Korea just days ago, and the largest rock to strike the earth since a meteor broke up over Siberia's Tunguska river in 1908. Despite its incredible power, the rock evaded detection by astronomers. Estimates show it was likely only 15 meters across — too small to be seen by networks searching for near earth asteroids." Today's meteor event came a day after California scientists proposed a system to vaporize asteroids that threaten Earth. Of course, the process needs to be started when the asteroid is still tens of millions of kilometers away; there's no chance to shoot down something that's already arrived. -
Obama Blocks Chinese Wind Farms In Oregon Over National Security
Hugh Pickens writes "Reuters reports that President Barack Obama has invoked a little-used law to block a privately owned Chinese company from building wind turbines close to a Navy military site in Oregon due to national security concerns. 'There is credible evidence that leads me to believe' that Ralls Corp, Sany Group and the two Sany Group executives who own Ralls 'might take action that threatens to impair the national security of the United States,' said Obama in issuing his decision. The military uses the Oregon naval facility to test unmanned drones and the EA-18G 'Growler.' The electronic warfare aircraft accompanies US fighter bombers on missions and protectively jams enemy radar, destroying them with missiles along the way. At the Oregon site, the planes fly as low as 60 m and at almost 480 km/h. The administration would not say what risks the wind farm purchases presented but the Treasury Department said the Committee on Foreign Investments in the United States, known as CFIUS, made its recommendation to Obama after receiving an analysis of the potential threats from the Office of the Director of National Intelligence. The last time a president used the law to block a transaction was in 1990, when George H.W. Bush voided the sale of an aerospace company, Mamco Manufacturing, to a Chinese agency." -
Unauthorized iOS Apps Leak Private Data Less Than Approved Ones
Sparrowvsrevolution writes "In the wake of news that the iPhone app Path uploads users' entire contact lists without permission, Forbes dug up a study from a group of researchers at the University of California at Santa Barbara and the International Security Systems Lab that aimed to analyze how and where iPhone apps transmit users' private data. Not only did the researchers find that one in five of the free apps in Apple's app store upload private data back to the apps' creators that could potentially identify users and allow profiles to be built of their activities; they also discovered that programs in Cydia, the most popular platform for unauthorized apps that run only on 'jailbroken' iPhones, tend to leak private data far less frequently than Apple's approved apps. The researchers ran their analysis on 1,407 free apps (PDF) on the two platforms. Of those tested apps, 21 percent of official App Store apps uploaded the user's Unique Device Identifier, for instance, compared with only four percent of unauthorized apps." -
Million Dollar Crowdturfing Industry Dupes Social Networks
New submitter bowlinearl writes "Three weeks ago Slashdot featured a story on the Chinese Water Army. A new study from researchers at UCSB delves even deeper into the problem of crowdturfing (full disclosure: I am one of the authors of the study). The study reveals that evil crowdsourcing services in China are a multi-million dollar industry, and that the number of jobs and the amount of money are growing exponentially. Hundreds of thousands of workers are involved, including a small contingent of career crowdturfers who each manage hundreds of accounts on social networks. The researchers observed the behavior of workers and the unwitting users who click on the generated spam by infiltrating the two largest crowdsourcing sites in China. However, crowdturfing isn't confined to China: the researchers discovered crowdsourcing sites in the U.S. that are 95% astroturf, as opposed to Amazon's Mechanical Turk, which actively polices itself, and is only 12% astroturf." -
An $80 Open Source Chemical Analyzer
An anonymous reader writes "A group of electrical engineering students at UCSB teamed up with some chemists and built an $80 gadget that can check water for arsenic, measure the level of vitamin C in orange juice, and also do simple DNA biosensor tests. The electronics in a blood sugar meter could do all of those things, but their firmware isn't easily hackable. All of the circuit schematics, gerber files, and software for this project are available on their project website. Another team at Denver Metro College is working to improve upon their design. Eventually, it could be used as a teaching tool in chemistry classrooms, or possibly to do blood and water tests in developing countries." -
EFF Takes On Cisco's Role In China
decora writes "Several years ago, writer Du Daobin posted several essays on the internet, protesting such things as unfair taxes and the corruption of the media. He was then charged with 'inciting subversion of state power,' arrested, and after many legal twists and turns, tortured in prison. Daobin, along with several other dissidents with similar stories, decided to sue Cisco Systems (PDF) earlier this year under the legal theory that it aided and abetted China's violation of the Torture Victim Protection Act of 1991. As the case moves forward, the Chinese Ministry of Public Security has stepped up its surveillance, harassment, and interrogation of Daobin and the others. The Electronic Frontier Foundation has now joined the Laogai Research Foundation to draw attention to the case. As part of its opening move, it has asked Cisco to make public statements in support of human rights, hoping that the company's influence with the Chinese government will provide some modicum of protection for the threatened dissidents." -
Why the World Is Running Out of Helium
jamie writes "The US National Helium Reserve stores a billion cubic meters of helium, half the world supply, in an old natural gasfield. The array of pipes and mines runs 200 miles from Texas to Kansas. In the name of deficit reduction, we're selling it all off for cheap. Physics professor and Nobel laureate Robert Richardson says: 'In 1996, the US Congress decided to sell off the strategic reserve and the consequence was that the market was swelled with cheap helium because its price was not determined by the market. The motivation was to sell it all by 2015. The basic problem is that helium is too cheap. The Earth is 4.7 billion years old and it has taken that long to accumulate our helium reserves, which we will dissipate in about 100 years. One generation does not have the right to determine availability forever.' Another view is The Impact of Selling the Federal Helium Reserve, the government study from 10 years ago that suggested the government's price would end up being over market value by 25% — but cautioned that this was based on the assumption that demand would grow slowly, and urged periodic reviews of the state of the industry." -
Torpig Botnet Hijacked and Dissected
An anonymous reader writes "A team of researchers at UC Santa Barbara have hijacked the infamous Torpig botnet for 10 days. They have released a report (PDF) that describes how that was done and the data they collected. They observed more than 180K infected machines (this is the number of actual bots, not just IP addresses), collected 70GB of data stolen by the Torpig trojan, extracted almost 10K bank accounts and credit card numbers worth hundreds of thousands of dollars in the underground market, and examined the privacy threats that this trojan poses to its victims. Considering that Torpig has been around at least since 2006, isn't it time to finally get rid of it?" -

Visualizing Data Inside the 30-ft Allosphere
TEDChris writes "The Allosphere, being created at UC Santa Barbara, is the most ambitious attempt yet at creating powerful 3d visualizations of raw scientific data, such as the structure of a crystal, or how quantum effects take place. Researchers watch from a bridge inside the 30-foot sphere, looking at data projected 360 degrees around them and listening to 3D sound. The first major public demo of the facility has just been posted at TED.com. Optimists would argue that many of the greatest scientific breakthroughs happened through a new visual way of imagining data. Penicillin and relativity come to mind. So this is either a killer new research vehicle, an incredible toy, or just an insanely expensive art project." -
William Gibson's AGRIPPA Recovered and Revealed
Bud Cook writes "While the text of William Gibson's elusive electronic poem AGRIPPA is widely posted around the Web, it has not been seen in its original incarnation — custom-built software designed to scroll the poem through a single play before encrypting each line with an RSA algorithm — since 1992. Today is the 16th anniversary, to the day, of the poem's initial release. A team of scholars at the University of Maryland and UC Santa Barbara used forensic computing to restore the code from an original diskette loaned by a collector and have placed video of the complete 'run,' as well as never-before-seen footage from the night of AGRIPPA's public debut in 1992, up on a Web site called the Agrippa Files. There's also a detailed essay documenting the forensic process, plus a mess of stills, screenshots, and a copy of the disk image itself." -
Video Shows Easy Hacking of E-Voting Machines
Mike writes "The Security Group at the University of California in Santa Barbara has released the video that shows the attacks carried out against the Sequoia voting system. The video shows an attack where a virus-like software spreads across the voting system. The coolest part of the video is the one that shows how the 'brainwashed' voting terminals can use different techniques to change the votes even when a paper audit trail is used. Pretty scary stuff. The video is absolute proof that these types of attacks are indeed feasible and not just a conspiracy theory. Also, the part that shows how the 'tamperproof' seals can be completely bypassed in seconds is very funny (and quite disturbing at the same time)." -

Evanescent Lasers to Speed Up Data Transmission
Roland Piquepaille writes "Researchers at UC Santa Barbara (UCSB) have built the world's first mode-locked silicon evanescent laser. But what is an 'evanescent' laser? It is a step toward 'combining lasers and other key optical components with the existing electronic capabilities in silicon.' In other words, this research work will provide a way to integrate optical and electronic functions on a single chip. As these evanescent lasers can produce stable short pulses of laser light, they will be useful for many optical applications, such as high-speed data transmission or highly accurate optical clocks." -
5000 Cylinder Recordings Placed Online
Jon Noring writes "The Department of Special Collections at the University of California Santa Barbara (UCSB) Davidson Library recently placed online, with free access, over 5000 sound recordings as part of its Cylinder Preservation and Digitization Project. These recordings date from the 1890's to the 1920's, all transfered from Edison cylinders using state-of-the-art equipment. The restorations are first-class, using CEDAR tools. Besides MP3 and streaming audio, the raw transfers are also available for diy'ers to try their own hand at audio restoration. For those who like their music 'hot', there's not much there since most of the cylinders predate the start of the Jazz Era (ca. 1917), but there is some early 'mouldy fygge' dance-type jazz, like 1920's 'Peggy' by Lopez and Hamilton's Kings of Harmony Orchestra." -

Results in for UCSB Capture the Flag Contest
Thorsten Holz writes "A few hours ago, the UCSB International Capture The Flag (CTF) contest ended. The CTF contest is a multi-site, multi-team hacking contest in which a number of teams compete independently against each other. It is the biggest contest worldwide and different from the DEFCON CTF because it involves nine educational institutions spread worlwide. Our team (called '0ld Eur0pe') managed to get second place, although our VMware image was 'rm -rf'ed during the contest! The final scoreboard shows the result and some impressions can be found at our homepage." Update: 06/12 00:17 GMT by T : Thanks to reader Bob MacSlack, who spotted my goof and corrects it thus: "The article incorrectly attributes the contest to UC Berkeley. UCSB is actually UC Santa Barbara." -

Why Alien Species Thrive
planux writes "The Sacramento Bee has an interesting article about why invasive animal species thrive, pushing out native species -- sometimes to the point of extinction. Kevin Lafferty, a U.S. Geological Survey marine ecologist at the Western Ecological Research Center in Santa Barbara says "Invasive species end up with about half the parasites, or diseases, they had at home." Animals with an average of 16 parasites on their home turf typically bring about three of the parasites with them to new locations. And only about four new parasites will typically adapt to attack the invading species. Net gain: 9 fewer parasites!" -
UCSB Bans Windows NT/2000 in the Dorms

Universe is Flat
D Anderson n'Swaart writes: "BBC News is reporting that a recent experiment called Project Boomerang, conducted with a super-sensitive telescope suspended 40 km above Antarctica, has provided powerful new evidence to support the current trend in scientific thinking that the fabric of space is essentially flat, and not curved as Einstein postulated. The one billion measurements gathered took three weeks to analyse on a Cray T3E supercomputer, and have provided insights on the creation of the universe, and suggest that it will continue to expand indefinitely without collapsing in a Big Crunch." -
MAP Satellite Launch
PineGreen writes: "Tomorrow, MAP Satellite is to be launched. MAP is the first space mission to measure Cosmic Microwave Background (CMB) fluctuations after the famous COBE who was first to detect fluctuations in the CMB. It is supposed to do the job with an unprecedented accuracy. There were several successful balloon experiments (Boomerang, Maxima) and interferometer experiments (VSA, DASI, CBI), some of which still haven't published their data. But of course, we are all waiting for the big European Planck mission in 2007. Measuring CMB fluctuations can tell us a lot about the universe in which we live, its constituents and its geometrical properties." -
Universe's Curvature Measured?
jmobiusmaximus writes "Right next to the wormhole site on the BBC News page is an article about the results of the Boomerang project in Antarctica. This resulted in a new map of the 2.7K cosmic microwave background radiation, which is thought to be a remnant of the energy released in the Big Bang. The BBC News synopsis isn't bad, and has some links that will answer most "WTF?" questions. For those of you who have taken a little bit of physics, the original Nature article is better. This could have a large impact on our understanding of the universe's evolution and will probably be the source of much debate in the near future. "
