A New Use For McDonald's Used Cooking Oil: 3D Printing (cnn.com) 73

An anonymous reader quotes a report from CNN: Professor Andre Simpson had a problem. The University of Toronto's Scarborough campus was paying through the nose for a crucial material for its 3D printer. Few would have guessed McDonald's would come to the rescue. Simpson is director of the school's Environmental NMR Center dedicated to environmental research. Central to this research is an analytical tool called the NMR spectrometer. NMR stands for nuclear magnetic resonance and is technically similar to how an MRI works for medical diagnostics. Simpson had bought a 3D printer for the lab in 2017. He hoped to use it to build custom parts that kept organisms alive inside of the NMR spectrometer for his research. But the commercial resin he needed for high-quality light projection 3D printing (where light is used to form a solid) of those parts was expensive.

The dominant material for light projection printing is liquid plastic, which can cost upward of $500 a liter, according to Simpson. Simpson closely analyzed the resin and spotted a connection. The molecules making up the commercial plastic resin were similar to fats found in ordinary cooking oil. What came next was the hardest part of the two-year experiment for Simpson and his team of 10 students -- getting a large sample batch of used cooking oil. "We reached out to all of the fast-food restaurants around us. They all said no," said Simpson. Except for McDonald's.
After filtering out chunks of food particles and experimenting with the oil for several months, the team was able to successfully print a high-quality butterfly with details as minute as 100 micrometers in size.

"The experiment yielded a commercially viable resin that Simpson estimates could be sourced as cheaply as 30 cents a liter of waste oil," reports CNN. Another bonus: it is biodegradable.

Simpson and his team published their research in December 2019 in industry publication ACS Sustainable Chemistry & Engineering.

Google Says Developers Can Now Purchase Latest Smart Glasses (bloomberg.com) 38

Google is making it easier for developers to purchase the latest version of its smart glasses, with the company saying on Tuesday that the Glass Enterprise Edition 2 is now available from some hardware resellers. From a report: "We've seen strong demand from developers and businesses who are interested in building new, helpful enterprise solutions for Glass," Google said in a blog post, adding that the new headset was already being used by people with jobs in logistics, manufacturing and field services."

Microsoft Announces Plan To Support DoH In Windows (microsoft.com) 97

New submitter Shad0wz writes: Microsoft's Core Network team just announced they plan on supporting DoH in the Windows resolver. In the blog post, the company writes: Providing encrypted DNS support without breaking existing Windows device admin configuration won't be easy. However, at Microsoft we believe that "we have to treat privacy as a human right. We have to have end-to-end cybersecurity built into technology." We also believe Windows adoption of encrypted DNS will help make the overall Internet ecosystem healthier. There is an assumption by many that DNS encryption requires DNS centralization. This is only true if encrypted DNS adoption isn't universal. To keep the DNS decentralized, it will be important for client operating systems (such as Windows) and Internet service providers alike to widely adopt encrypted DNS. With the decision made to build support for encrypted DNS, the next step is to figure out what kind of DNS encryption Windows will support and how it will be configured. Here are our team's guiding principles on making those decisions:

Windows DNS needs to be as private and functional as possible by default without the need for user or admin configuration because Windows DNS traffic represents a snapshot of the user's browsing history. To Windows users, this means their experience will be made as private as possible by Windows out of the box. For Microsoft, this means we will look for opportunities to encrypt Windows DNS traffic without changing the configured DNS resolvers set by users and system administrators.
Privacy-minded Windows users and administrators need to be guided to DNS settings even if they don't know what DNS is yet. Many users are interested in controlling their privacy and go looking for privacy-centric settings such as app permissions to camera and location but may not be aware of or know about DNS settings or understand why they matter and may not look for them in the device settings.
Windows users and administrators need to be able to improve their DNS configuration with as few simple actions as possible. We must ensure we don't require specialized knowledge or effort on the part of Windows users to benefit from encrypted DNS. Enterprise policies and UI actions alike should be something you only have to do once rather than need to maintain.
Windows users and administrators need to explicitly allow fallback from encrypted DNS once configured. Once Windows has been configured to use encrypted DNS, if it gets no other instructions from Windows users or administrators, it should assume falling back to unencrypted DNS is forbidden.

Volkwagen Finally Pleads Guilty On 'Dieselgate' Charges (cnet.com) 115

Friday Volkswagen admitted in court that they'd committed fraud in their diesel emissions tests, also pleading guilty to falsifying statements and obstruction of justice. An anonymous reader quotes CNET: It marks the first time VW admitted guilt in any court in the world, according to a VW spokesman speaking to Reuters. The judge overseeing the case in the U.S. District Court in Detroit accepted the plea and will issue a sentence at a hearing on April 21. "The agreements that we have reached with the US government reflect our determination to address misconduct that went against all of the values Volkswagen holds so dear," Volkswagen said in an emailed statement... The road to Dieselgate's conclusion still has plenty of pavement, though. The company is still under investigation by the Securities and Exchange Commission and Internal Revenue Service. And that's in the US alone.
"VW AG is pleading guilty to all three counts because it is guilty on all three counts," the company's general counsel told the judge. Reuters also reports that VW offered to buy back half a million vehicles just in America, and agreed to spend up to $25 billion in the U.S. to address claims from unhappy owners.

Of course they can.
Most of the dissidents in this country are well known and tracked as closely as if they had implanted GPS transmitters.

The same people show up at every protest, get arrested and let go by every city they visit by liberal judges. A phone call from Washington, a hint of a under cover arrangement, and a get out of jail free card.

Dozens if not hundreds of arrests, and they just walk.

Why? The Feds get more information from them running around loose than they would if they were in jail.

No One's Bidding on The Shadow Brokers' Stolen NSA Hacking Tools (vice.com) 51

That group auctioning the NSA's hacking tools is "very upset" no one's bidding on them. An anonymous Slashdot reader quotes Motherboard: "TheShadowBrokers" authored another bizarre rant expressing their annoyance at the seeming lack of interest in ponying up bitcoins to release their full set of stolen files. "Peoples is having interest in free files ... But people is no interest in #EQGRP_Auction," the mysterious hacker group complained in a ranting post on Medium, which seems to be purposely written in Borat-style broken English. "TheShadowBrokers is thinking this is information communication problem."

The message also blindly lashes out at hackers, foreign intelligence services, and basically anyone else who hasn't bid on the files... At the time of this writing, TheShadowBrokers have only received bids for a total of 1.76 bitcoins -- or about $1,082 -- far below the group's asking price of $1 million.

At least five transactions came from a prankster who was trying to Rickroll the group with bitcoin addresses containing the words "Never Gonna Give You Up."

Comment Re:Not Client Side? (Score 2) 19

Google would be the first with a cloud offering, encryption integration points, and an enterprise encrypted document play that could be federated. The fear is, as some other posters noted, will Google commit to this or just do it for 2 years and then dump the whole thing?

If it has a revenue stream, (paying customers - not advertising) they probably won't dump it.
