Unknown Language Discovered in Malaysia

Researchers have cataloged close to 7, 000 distinct human languages on Earth, per Linguistic Society of America’s latest count. That may seem like a pretty exhaustive list, but it hasn’t stopped anthropologists and linguists from continuing to encounter new languages, like one recently discovered in a village in the northern part of the Malay Peninsula. From a report: According to a press release, researchers from Lund University in Sweden discovered the language during a project called Tongues of the Semang. The documentation effort in villages of the ethnic Semang people was intended to collect data on their languages, which belong to an Austoasiatic language family called Aslian. While researchers were studying a language called Jahai in one village, they came to understand that not everyone there was speaking it. “We realized that a large part of the village spoke a different language. They used words, phonemes and grammatical structures that are not used in Jahai, ” says Joanne Yager, lead author of the study, which was published in the journal Linguist Typology. “Some of these words suggested a link with other Aslian languages spoken far away in other parts of the Malay Peninsula.” Read more of this story at Slashdot.

Physicists Made An Unprecedented 53 Qubit Quantum Simulator

Two teams of researchers have published papers [1, 2] in the journal Nature detailing how they were able to create unprecedented quantum simulators consisting of over 50 qubits. The University of Maryland team and National Institute of Standards and Technology team — the two teams behind one of the two new papers — were able to create a quantum simulator with 53 qubits. Motherboard reports: Quantum simulators are a special type of quantum computer that uses qubits to simulate complex interactions between particles. Qubits are the informational medium of quantum computers, analogous to a bit in an ordinary computer. Yet rather than existing as a 1 or 0, as is the case in a conventional bit, a qubit can exist in some superposition of both of these states at the same time. For the Maryland experiment, each of the qubits was a laser cooled ytterbium ion. Each ion had the same electrical charge, so they repelled one another when placed in close proximity. The system created by Monroe and his colleagues used an electric field to force the repelled ions into neat rows. At this point, lasers are used to manipulate all the ytterbium qubits into the same initial state. Then another set of lasers is used to manipulate the qubits so that they act like atomic magnets, where each ion has a north and south pole. The qubits either orient themselves with their neighboring ions to form a ferromagnet, where their magnetic fields are aligned, or at random. By changing the strength of the laser beams that are manipulating the qubits, the researchers are able to program them to a desired state (in terms of magnetic alignment). According to Zhexuan Gong, a physicist at the University of Maryland, the 53 qubits can be used to simulate over a quadrillion different magnetic configurations of the qubits, a number that doubles with each additional qubit added to the array. As these types of quantum simulators keep adding more qubits into the mix, they will be able to simulate ever more complex atomic interactions that are far beyond the capabilities of conventional supercomputers and usher in a new era of physics research. Another team from Harvard and Maryland also released a paper today in which it demonstrated a quantum simulator using 51 qubits. Read more of this story at Slashdot.

Study Finds SpaceX Investment Saved NASA Hundreds of Millions

schwit1 shares a report from Popular Mechanics: When a SpaceX Dragon spacecraft connected with the International Space Station on May 25, 2012, it made history as the first privately-built spacecraft to reach the ISS. The Dragon was the result of a decision 6 years prior — in 2006, NASA made an “unprecedented” investment in SpaceX technology. A new financial analysis shows that the investment has paid off, and the government found one of the true bargains of the 21st century when it invested in SpaceX. A new research paper by Edgar Zapata, who works at Kennedy Space Center, looks closely at the finances of SpaceX and NASA. “There were indications that commercial space transportation would be a viable option from as far back as the 1980s, ” Zapata writes. “When the first components of the ISS were sent into orbit 1998, NASA was focused on “ambitious, large single stage-to-orbit launchers with large price tags to match.” For future commercial crew missions sending astronauts into space, Zapata estimates that it will cost $405 million for a SpaceX Dragon crew deployment of 4 and $654 million for a Boeing Starliner, which is scheduled for its first flight in 2019. That sounds like a lot, and it is, but Zapata estimates that its only 37 to 39 percent of what it would have cost the government. Read more of this story at Slashdot.

Chicago School Official: US IT Jobs Offshored Because ‘We Weren’t Making Our Own’ Coders

theodp writes: In a slick new video, segments of which were apparently filmed looking out from Google’s Chicago headquarters giving it a nice high-tech vibe, Chicago Public Schools’ CS4ALL staffers not-too-surprisingly argue that creating technology is “a power that everyone needs to have.” In the video, the Director of Computer Science and IT Education for the nation’s third largest school district offers a take on why U.S. IT jobs were offshored that jibes nicely with the city’s new computer science high school graduation requirement. From the transcript: “People still talk about it’s all offshored, it’s all in India and you know, there are some things that are there but they don’t even realize some of the reasons that they went there in the first place is because we weren’t making our own.” Read more of this story at Slashdot.

Hacker Claims To Have Decrypted Apple’s Secure Enclave Processor Firmware

According to iClarified, a hacker by name of “xerub” has posted the decryption key for Apple’s Secure Enclave Processor (SEP) firmware. “The security coprocessor was introduced alongside the iPhone 5s and Touch ID, ” reports iClarified. “It performs secure services for the rest of the SOC and prevents the main processor from getting direct access to sensitive data. It runs its own operating system (SEPOS) which includes a kernel, drivers, services, and applications.” From the report: The Secure Enclave is responsible for processing fingerprint data from the Touch ID sensor, determining if there is a match against registered fingerprints, and then enabling access or purchases on behalf of the user. Communication between the processor and the Touch ID sensor takes place over a serial peripheral interface bus. The processor forwards the data to the Secure Enclave but can’t read it. It’s encrypted and authenticated with a session key that is negotiated using the device’s shared key that is provisioned for the Touch ID sensor and the Secure Enclave. The session key exchange uses AES key wrapping with both sides providing a random key that establishes the session key and uses AES-CCM transport encryption. Today, xerub announced the decryption key “is fully grown.” You can use img4lib to decrypt the firmware and xerub’s SEP firmware split tool to process. Decryption of the SEP Firmware will make it easier for hackers and security researchers to comb through the SEP for vulnerabilities. Read more of this story at Slashdot.

Seattle’s $15 Minimum Wage May Be Hurting Workers, Report Finds

As companies look for ways to cut costs, Seattle’s $15 minimum wage law may be hurting hourly workers instead of helping them, according to a new report. From a USA Today article: A report (PDF) from the University of Washington (UW), found that when wages increased to $13 in 2016, some companies may have responded by cutting low-wage workers’ hours. The study, which was funded in part by the city of Seattle, found that workers clocked 9 percent fewer hours on average, and earned $125 less each month after the most recent increase. “If you’re a low-skilled worker with one of those jobs, $125 a month is a sizable amount of money, ” Mark Long, a UW public-policy professor and an author of the report told the Seattle Times. “It can be the difference between being able to pay your rent and not being able to pay your rent.” Read more of this story at Slashdot.

Only 36 Percent of Indian Engineers Can Write Compilable Code, Says Study

New submitter troublemaker_23 quotes a report from ITWire: Only 36% of software engineers in India can write compilable code based on measurements by an automated tool that is used across the world, the Indian skills assessment company Aspiring Minds says in a report. The report is based on a sample of 36, 800 from more than 500 colleges across India. Aspiring Minds said it used the automated tool Automata which is a 60-minute test taken in a compiler integrated environment and rates candidates on programming ability, programming practices, run-time complexity and test case coverage. It uses advanced artificial intelligence technology to automatically grade programming skills. “We find that out of the two problems given per candidate, only 14% engineers are able to write compilable codes for both and only 22% write compilable code for exactly one problem, ” the study said. It further found that of the test subjects only 14.67% were employable by an IT services company. When it came to writing fully functional code using the best practices for efficiency and writing, only 2.21% of the engineers studied made the grade. Read more of this story at Slashdot.
