Penn Engineering Online Learning has just launched a new Specialization called Introduction to Programming with Python and Java. This Specialization moves quickly; it starts out by teaching basic concepts in Python and ramps up to more complex subjects such as object-oriented programming and data structures in Java. By the time learners complete this series of […]

Elementary particles part ways with their properties
“Spooky action at a distance,” Einstein’s summation of quantum physics, has been a criticism of quantum mechanics since the field emerged. So far, descriptions of entangled particles to explain their apparently faster-than-light responses, and even explanations for the phase shifts induced by an electromagnetic field in regions where it is zero—the “Aharonov-Bohm” effect—have mostly addressed these concerns. However, recent theoretical and…
Hearts, airlocks, and asteroids: New research flies on 21st SpaceX cargo mission

Activists Turn Facial Recognition Tools Against the Police
An anonymous reader quotes a report from The New York Times: In early September, the City Council in Portland, Ore., met virtually to consider sweeping legislation outlawing the use of facial recognition technology. The bills would not only bar the police from using it to unmask protesters and individuals captured in surveillance imagery; they would also prevent companies and a variety…
Researchers Demonstrate In-Chip Watercooling
FallOutBoyTonto shares a report from Ars Technica: Part of the problem with liquid cooling solutions is that they’re limited by having to get the heat out of the chip and into the water in the first place. That’s led some researchers to consider running the liquid through the chip itself. Now, some researchers from Switzerland have designed the chip and cooling…
Google Removes Android App That Was Used To Spy On Belarusian Protesters
Google has removed an Android app from the Play Store that was used to collect personal information from Belarusians attending anti-government protests. ZDNet reports: The app, named NEXTA LIVE, was available for almost three weeks on the official Android Play Store, and was downloaded thousands of times and received hundreds of reviews. To get installs, NEXT LIVE claimed to be the…
Telegram Messaging App Proves Crucial To Belarus Protests
An anonymous reader quotes a report from The Associated Press: Every day, like clockwork, to-do lists for those protesting against Belarus’ authoritarian leader appear in the popular Telegram messaging app. They lay out goals, give times and locations of rallies with business-like precision, and offer spirited encouragement. The app has become an indispensable tool in coordinating the unprecedented mass protests that…
William English, Engineer Behind ‘The Mother of All Demos’, Dies at 91
An anonymous reader quotes The Los Angeles Times:
On Dec. 9, 1968, the then-small world of computer engineering was shaken to its core by a presentation of new technologies projected onto a screen in a San Francisco hall. The attendees at the historic event saw demonstrations of video conferencing, the first public use of a computer mouse, hyperlinking in which clicking a…
Facebook, Twitter, Google Face Free-Speech Test in Hong Kong
U.S. technology titans face a looming test of their free-speech credentials in Hong Kong as China’s new national-security law for the city demands local authorities take measures to supervise and regulate its uncensored internet. From a report: Facebook and its Instagram service, Twitter and YouTube, a unit of Alphabet’s Google, operate freely in the city even as they have been shut…
