How the CIA destroyed the socialist internet | Mashable #internet #history #privacy

In Mashable’s new three-part episode of our series on the digital age's dark side, Kernel Panic, we explore a startlingly advanced computer network developed in Salvador Allende's Chile of the 1970s. Called Project Cybersyn, the network was a centerpiece of Allende's effort to modernize the Chilean economy. It was developed in parallel with the American networks that would become the internet, at a moment in time in which President Nixon was trying to undermine the Chilean economy and overthrow Allende, the first democratically elected Marxist leader in Latin America.

Cybersyn, designed by a farthinking British theorist named Stafford Beer and run by a cadre of young revolutionary programmers, was an astonishing success. Using little more than old telephone wires and mothballed pre-war machinery, the Chilean program managed to build out a real-time data stream very much like the social media newsfeed of today, watching and monitoring the country's industry from a retro-futuristic control room in the capital.

More content by people, for people in Search #internet

Many of us have experienced the frustration of visiting a web page that seems like it has what we’re looking for, but doesn’t live up to our expectations. The content might not have the insights you want, or it may not even seem like it was created for, or even by, a person.

We work hard to make sure the pages we show on Search are as helpful and relevant as possible. To do this, we constantly refine our systems: Last year, we launched thousands of updates to Search based on hundreds of thousands of quality tests, including evaluations where we gather feedback from human reviewers.

“Quantum-Safe” Crypto Hacked by 10-Year-Old PC - IEEE Spectrum #security #blockchain

In theory, quantum computers can quickly solve problems it might take classical computers untold eons to solve. For example, much of modern cryptography relies on the extreme difficulty that classical computers face when it comes to mathematical problems such as factoring huge numbers. However, quantum computers can in principle run algorithms that can rapidly crack such encryption.

To stay ahead of this quantum threat, cryptographers around the world have spent the past two decades designing postquantum cryptography (PQC) algorithms. These are based on new mathematical problems that both quantum and classical computers find difficult to solve.

How to Estimate Distance Using Just Your Thumb #lifehack

  1. Hold your thumb in front of you (with your arm fully outstretched), and close one eye. Line up your thumb with an object whose size you have some sense of (for example, a car).
  2. Without moving your thumb, close your open eye, and open the other one. Your thumb will appear to be in a different place.
  3. Estimate how far your thumb “moved” relative to the object you’re looking at. For example, a car is about 15 feet long, so if your thumb moved half a car length, that’s about 7.5 feet.
  4. Multiply by 10. In this example, you’d calculate that the car is about 75 feet away from you.

Physical buttons outperform touchscreens in new cars, test finds | Vi Bilägare #hardware #automotive #safety

Physical buttons are increasingly rare in modern cars. Most manufacturers are switching to touchscreens – which perform far worse in a test carried out by Vi Bilägare. The driver in the worst-performing car needs four times longer to perform simple tasks than in the best-performing car.

A pizzeria owner made money buying his own $24 pizzas from DoorDash for $16 - The Verge #economy #internet

Apparently, this is one way that DoorDash does custoACmer acquisition — by bullying restaurants. But what’s funnier about Roy’s friend’s problem (and it was a real problem because of Yelp reviews and angry customers) is that DoorDash priced the pizzas incorrectly. “A pizza that he charged $24 for was listed as $16 by Doordash,” emphasis Roy’s. And then: “My third thought: Cue the Wall Street trader in me…..ARBITRAGE!!!!”

And so the story unfolds. “If someone could pay Doordash $16 a pizza, and Doordash would pay his restaurant $24 a pizza, then he should clearly just order pizzas himself via Doordash, all day long. You’d net a clean $8 profit per pizza [insert nerdy economics joke about there is such a thing as a free lunch],” wrote Roy. They order 10 pizzas this way, and it worked! The money was free, a seamless transfer from SoftBank’s deep venture capital-lined pockets to Roy’s friend’s business bank account. Eventually, in another series of what Roy hilariously calls “trades,” they just ordered pizza dough through DoorDash for $75 in pure profit.

“So over a few weeks, almost to humor me, we did a few of these ‘trades’. I was genuinely curious if Doordash would catch on but they didn’t,” wrote Roy. “Was this a bit shady? Maybe, but fuck Doordash. Note: I did confirm with my friend that he was okay with me writing this, and we both agreed, fuck Doordash.” (I reached out to DoorDash for comment and will update this story if they reply.)

How to build bigger biceps: A little exercise each day improves muscles more than one big weekly workout - Study Finds #health

Could the answer to getting builder muscles be quantity over quality? A new study finds just a little bit of exercise each day is better for the body than one intense workout session.

Researchers from Australia and Japan have found that just doing a handful of bicep curls each day, five days a week actually improves muscle strength more than continuously doing dozens of curls in a longer exercise routine once a week. Moreover, they found people don’t even have to work out at full intensity to achieve these results.

During their study, the team had two groups of volunteers perform “maximal voluntary eccentric bicep contractions” for four weeks while they measured each person’s muscle strength and muscle thickness. An eccentric contraction is when the muscle lengthens. In the case of a bicep curl, a person lengthens the muscle by lowering a heavy dumbbell.
