“Though Hamburg’s $843 million philharmonic is filled with stunning architectural gems, its most interesting feature is the central auditorium, a gleaming ivory cave built from 10,000 unique acoustic panels that line the ceiling, walls, and balustrades. The room looks almost organic—like a rippling, monochromatic coral reef—but bringing it to life was a technological feat.

The auditorium—the largest of three concert halls in the Elbphilharmonie—is a product of parametric design, a process by which designers use algorithms to develop an object’s form. Algorithms have helped design bridges, motorcycle parts, typefaces—even chairs. In the case of the Elbphilharmonie, Herzog and De Meuron used algorithms to generate a unique shape for each of the 10,000 gypsum fiber acoustic panels that line the auditorium’s walls like the interlocking pieces of a giant, undulating puzzle."

“For anything other than ASCII, Python 2 “strings” are broken. Python 3’s string handling is superb. The problem with it has only ever been that you don’t actually know how strings work. Instead of starting ignorant flamewars about it, learn how it works.”
I’ve found myself explaining Python 3’s str to people online more and more often lately. There’s this ridiculous claim about that Python 3’s string handling is broken or somehow worse than Python 2, and today I intend to put that myth to rest. Python 2 strings are broken, and Python 3 strings are sane. The only problem is that you don’t grok strings.

“On January 13, 2017, the Pardon Snowden campaign delivered more than 1 million signatures to the White House, from people asking President Obama to pardon Edward Snowden. This letter, from the heads of the American Civil Liberties Union, Amnesty International, and Human Rights Watch, accompanied the signatures.”

"Seeking to allay concerns about how the incoming commander-in-chief’s business ties would affect the way he governs, members of Donald Trump’s White House transition team assured the American public Friday that the president-elect has far too many conflicts of interest to favor any individual one. “The American people have absolutely nothing to worry about regarding Mr. Trump’s ethical integrity, as his conflicts of interest are simply too extensive for him to give preferential treatment to any one of them in particular,” said Trump senior advisor Kellyanne Conway, noting that the real estate magnate’s foreign and domestic holdings are so expansive and complex that it would be almost impossible for him to keep track of them all, let alone isolate one specifically and exploit it. “Every single citizen can rest assured that none of Mr. Trump’s vast array of investments will ever take precedence over any of the others. And even if one of his many business interests did stand to sway his position on an issue, another one of the thousands of other ventures he has a stake in would surely exert pressure to counteract it. So there’s no reason for concern at all.” Conway added that given how committed every member of the incoming administration was to upholding such rigorous principles, the American populace should not even waste their time by scrutinizing the White House’s ethics at all for the next four years."

‘WhatsApp’s end-to-end encryption relies on the generation of unique security keys, using the acclaimed Signal protocol, developed by Open Whisper Systems, that are traded and verified between users to guarantee communications are secure and cannot be intercepted by a middleman. However, WhatsApp has the ability to force the generation of new encryption keys for offline users, unbeknown to the sender and recipient of the messages, and to make the sender re-encrypt messages with new keys and send them again for any messages that have not been marked as delivered.

The recipient is not made aware of this change in encryption, while the sender is only notified if they have opted-in to encryption warnings in settings, and only after the messages have been re-sent. This re-encryption and rebroadcasting effectively allows WhatsApp to intercept and read users’ messages.

The security backdoor was discovered by Tobias Boelter, a cryptography and security researcher at the University of California, Berkeley. He told the Guardian: “If WhatsApp is asked by a government agency to disclose its messaging records, it can effectively grant access due to the change in keys.”’

“The case involved a woman who had spent considerable time in India, where multi-drug-resistant bacteria are more common than they are in the US. She had broken her right femur — the big bone in the thigh — while in India a couple of years back. She later developed a bone infection in her femur and her hip and was hospitalized a number of times in India in the two years that followed. Her last admission to a hospital in India was in June of last year.

The unnamed woman — described as a resident of Washoe County who was in her 70s — went into hospital in Reno for care in mid-August, where it was discovered she was infected with what is called a CRE — carbapenem-resistant enterobacteriaceae. That’s a general name to describe bacteria that commonly live in the gut that have developed resistance to the class of antibiotics called carbapenems — an important last-line of defense used when other antibiotics fail. CDC Director Dr. Tom Frieden has called CREs “nightmare bacteria” because of the danger they pose for spreading antibiotic resistance.

In the woman’s case, the specific bacteria attacking her was called Klebsiella pneumoniae, a bug that often causes of urinary tract infections.

Testing at the hospital showed resistance to 14 drugs — all the drug options the hospital had, said Lei Chen, a senior epidemiologist with Washoe County Health District and an author of the report. “It was my first time to see a [resistance] pattern in our area,” she said.

A sample was sent to the CDC in Atlanta for further testing, which revealed that nothing available to US doctors would have cured this infection. Kallen admitted people in this field experience a sinking feeling when they’re faced with a superbug like this one.”
The “nightmare bacteria” could fend off 26 different drugs

“As a young man Mr Zhou spent time in the US and worked as a Wall Street banker.

He returned to China after the communist victory in 1949 and was put in charge of creating a new writing system using the Roman alphabet.

"We spent three years developing Pinyin. People made fun of us, joking that it had taken us a long time to deal with just 26 letters," he told the BBC in 2012.

Before Pinyin was developed, 85% of Chinese people could not read, now almost all can.

Pinyin has since become the most commonly used system globally, although some Chinese communities - particularly in Hong Kong and Taiwan - continue to use alternatives.”
Zhou Youguang, who created a system to turn characters into words using Roman letters, dies aged 111.

"We’re excited to announce the release of Project Wycheproof, a set of security tests that check cryptographic software libraries for known weaknesses. We’ve developed over 80 test cases which have uncovered more than 40 security bugs (some tests or bugs are not open sourced today, as they are being fixed by vendors). For example, we found that we could recover the private key of widely-used DSA and ECDHC implementations. We also provide ready-to-use tools to check Java Cryptography Architecture providers such as Bouncy Castle and the default providers in OpenJDK.

The main motivation for the project is to have an achievable goal. That’s why we’ve named it after the Mount Wycheproof, the smallest mountain in the world. The smaller the mountain the easier it is to climb it!

In cryptography, subtle mistakes can have catastrophic consequences, and mistakes in open source cryptographic software libraries repeat too often and remain undiscovered for too long. Good implementation guidelines, however, are hard to come by: understanding how to implement cryptography securely requires digesting decades' worth of academic literature. We recognize that software engineers fix and prevent bugs with unit testing, and we found that many cryptographic issues can be resolved by the same means."

"Existing methods of protecting users against server compromise require users to manually verify recipients’ accounts in-person. This simply hasn’t worked. The PGP web-of-trust for encrypted email is just one example: over 20 years after its invention, most people still can't or won’t use it, including its original author. Messaging apps, file sharing, and software updates also suffer from the same challenge.

One of our goals with Key Transparency was to simplify this process and create infrastructure that allows making it usable by non-experts. The relationship between online personas and public keys should be automatically verifiable and publicly auditable. Users should be able to see all the keys that have been attached to an account, while making any attempt to tamper with the record publicly visible. This also ensures that senders will always use the same keys that account owners are verifying."

Still tough to imagine the long-term use cases here, since Allo with desktop capabilities, group chats, and Assistant integration seem far more powerful than Hangouts for companies.
Google Hangouts is a fantastic service, but little by little, it’s fading into the background like the dozen other Google messaging services before it. However, Google has no plans to kill th…

Fantastic food. Very tasty, amusing menu names and overall a strong and consistent theme going for these folks. The music is too loud, and the music choice isn't great. Otherwise, highly recommended.

Fantastic doughnuts. Tried two of their flavors: sourdough, and peanut butter and jelly. Both were fantastic, though if you're not big on sweets, the PB&J isn't recommended unless you portion it out. The sourdough was easily the best doughnut I've ever had.

Impressive selection and variety for the price. Big discounts on some very notable brands, and there are plenty of items with reasonable sizes still in stock (not XL, etc).

Service is fine, food is good as pub-style food goes. Price is acceptable for the size of meal, but could be lower.

Simply enormous. Layout is great with sections dedicated to various areas of the tech world in a far better way than other Best Buy locations. Really liked the dedicated store areas for Google, Apple and Microsoft.
