Cambridge Engineering alumnus Hal Evans has built a fully-functioning replica of a 1930s Polish cyclometer -- an electromechanical cryptologic device that was designed to assist in the decryption of German Enigma ciphertext. The replica currently resides in King's College, Cambridge. TechXplore reports: Work on the hardware-based replica began in 2018, as part of Hal's fourth year Master's project under the supervision of King's College Fellow and Senior Tutor Dr. Tim Flack. The aim was to investigate further into cryptologist Marian Rejewski's cyclometer -- an early forerunner to Cambridge University mathematician Alan Turing's machine, known as the Bombe, which was used to crack the German Enigma code during the Second World War. Hal said he chose to work on the cyclometer as it was the very first machine used to assist the decryption effort. To his knowledge, the replica is the first fully-functioning hardware-based electromechanical cyclometer to exist since the years preceding the Second World War. The original machines would have been destroyed in 1939 to prevent them from falling into the hands of German invaders. Rejewski's cyclometer exploited the German's procedure at the time of double encipherment of the Enigma message key, and semi-automated the process for calculating what were known as 'characteristics' for every possible Enigma rotor starting position. There were more than 100,000 of these rotor starting positions, and they each needed their characteristic to be calculated and catalogued in a card index system. The cyclometer therefore eliminated the arduous task of calculating these characteristics by hand. The machine consisted of, in effect, two interlinked Enigma systems side-by-side -- one offset by three positions relative to the other -- and 26 lamps and switches to cover the alphabet. On operation, a certain number of bulbs illuminated, indicating the lengths of the characteristics. These were recorded for every single possible rotor starting position to create an immense look-up catalogue. Once this was completed, obtaining the daily Enigma rotor starting settings to decode messages was a simple matter of intercepting enough messages and referencing the catalogue, taking only a matter of minutes.

Millions of the creatures took to the skies

Two men remain in police custody

Grant Imahara, an electrical engineer and roboticist who hosted the popular science show MythBusters and Netflix's White Rabbit Project, has died suddenly following a brain aneurysm. He was 49. From The Hollywood Reporter: An electrical engineer and roboticist by training, he joined Discovery's MythBusters in its third season, replacing Scottie Chapman and was with the show until 2014 when he left with with co-hosts Kari Byron and Tory Belleci. The trio would reunite in 2016 for Netflix's White Rabbit Project which lasted for one season. On MythBusters, Imahara used his technical expertise to design and build robots for the show and also operated the computers and electronics needed to test myths. Born in Los Angeles, Imahara studied electrical engineering at the University of Southern California (though he briefly had doubts and wanted to become a screenwriter) before combining the two passions and landing a post-graduation gig at Lucasfilm-associated THX labs. In his nine years at Lucasfilm, he worked for the company's THX and Industrial Light and Magic (ILM) divisions. In his years at ILM he became chief model maker specializing in animatronics and worked on George Lucas' Star Wars prequels, as well as The Matrix Reloaded, The Matrix Revolutions, Galaxy Quest, XXX: State of the Union, Van Helsing, The Lost World: Jurassic Park, A.I. Artificial Intelligence and Terminator 3: Rise of the Machines. [...] Imahara also starred in several episodes of the fan-made web series Star Trek Continues. He played Hikaru Sulu, a lieutenant, helmsman and third officer on the USS Enterprise, in the show that was an unofficial continuation of Star Trek: The Original Series. "We are heartbroken to hear this sad news about Grant. He was an important part of our Discovery family and a really wonderful man. Our thoughts and prayers go out to his family," a representative for Discovery said in a statement on Monday.

An anonymous reader quotes a report from The New York Times: Researchers in Singapore have developed an apparatus that can be placed in a window to reduce incoming sound by 10 decibels. The system was created by a team of scientists, including Masaharu Nishimura, who came up with the basic concept, and Bhan Lam, a researcher at Nanyang Technological University in Singapore. Their results were published on Thursday in Scientific Reports. The prototype is not yet the most practical device in real world conditions, but it points the way toward the development of technologies that may help ease the strain of noisy city living. Borrowing from the same technological principles used in noise-canceling headphones, the team expanded the concept to fit an entire room by placing 24 small speakers in a window. The speakers emit sound waves that correspond to the incoming racket and neutralize it -- or, at least some of it. The system is based on the frequency of the sound waves and, for now, the optimal range is between 300 and 1,000 hertz. [...] The system uses a microphone outside the window to detect the repeating sound waves of the offending noise source, which is registered by a computer controller. That in turn deciphers the proper wave frequency needed to neutralize the sound, which is transmitted to the array of speakers on the inside of the window frame. The speakers then emit the proper "anti" waves, which cancel out the incoming waves, and there you have it: near blissful silence. Unfortunately, there are some limitations. The system works best from the types of steady noise sources found within the optimal frequency range and isn't great at neutralizing sporadic noises. Also, since human voices don't fit within most of that range, they won't be canceled out.

Engineers from Kenoteq are working to reinvent the humble clay-fired brick, which has remained largely the same for thousands of years and causes significant environmental problems. Not only are the majority of brick kilns required to produce bricks heated by fossil fuels, but the bricks that are made must be transported to construction sites, generating more carbon emissions. CNN reports: [Gabriela Medero, a professor of Geotechnical and Geoenvironmental Engineering at Scotland's Heriot-Watt University] joined forces with fellow engineer Sam Chapman and founded Kenoteq in 2009. The company's signature product is the K-Briq. Made from more than 90% construction waste, Medero says the K-Briq -- which does not need to be fired in a kiln -- produces less than a tenth of the carbon emissions of conventional bricks. With the company testing new machinery to start scaling up production, Medero hopes her bricks will help to build a more sustainable world. To make it, construction and demolition waste including bricks, gravel, sand and plasterboard is crushed and mixed with water and a binder. The bricks are then pressed in customized molds. Tinted with recycled pigments, they can be made in any color. [...] Kenoteq currently operates one workshop in Edinburgh, which can produce three million K-Briqs a year. Medero is looking at scaling up -- but it's hard to create a revolution in construction. Over the next 18 months, Medero plans to get K-Briq machinery on-site at recycling plants. This will increase production while reducing transport-related emissions, she says, because trucks can collect K-Briqs when they drop off construction waste. "We need to have ways of building sustainably, with affordable, good quality materials that will last."

California has opened its own antitrust probe into Google, leaving just one state that has yet to do so. "In September, attorneys general from 48 states, Puerto Rico and the District of Columbia announced an antitrust investigation into Google focused on the company's dominance of the advertising technology market," reports Politico. "Over the past 10 months, that investigation -- led by Texas -- has expanded into other aspects of the company's business, including its conduct in the search market." From the report: California -- which houses Google's headquarters in Mountain View -- was the most notable holdout in the multi-state group, and Democratic Attorney General Xavier Becerra has repeatedly declined to answer questions about why the state wasn't a participant. The California antitrust probe is a separate investigation from the multi-state effort, two of the individuals said. All of the individuals spoke on condition of anonymity to talk openly about a confidential probe. Alabama is now the only state that is not investigating the company. It was not immediately clear what aspect of Google's business California is targeting. Google has previously been in California's crosshairs over antitrust concerns. In the early 2010s, California was among five states that investigated Google alongside the Federal Trade Commission over allegations the tech giant biased its search results to favor its own products. The FTC opted against filing an antitrust suit and closed its probe in January 2013. California and the other states, which included Texas, New York, Oklahoma and Ohio, later closed their probes in 2014. California has its own antitrust laws, the Cartwright Act and the Unfair Competition Act, that are sometimes interpreted more broadly than the U.S. federal antitrust law. Unlike federal antitrust law, California's laws do allow government enforcers to seek restitution or civil penalties for violations.
