A Glass Battery That Keeps Getting Better

A Glass Battery That Keeps Getting Better

(Spectrum had profiled him and his battery technology the year before, following an initial announcement about his group’s new glass battery.) Goodenough and collaborators claimed they’d developed a non-flammable lithium battery (whose electrolyte was based on a glass powder) that had twice the energy density of traditional lithium-ion batteries. Maria Helena Braga, associate professor and head of the engineering physics department at the University of Porto in Portugal, has been one of Goodenough’s chief collaborators in the spate of recent papers around the glass battery.

ARKit 3 Ushers in RealityKit, Priming Us for AR Glasses

ARKit 3 Ushers in RealityKit, Priming Us for AR Glasses

Prior to ARKit 3 and RealityKit, a lot of augmented reality tooling was handled by SceneKit, Apple’s toolkit meant for 2D games. RealityKit is a brand new toolkit that is focused on 3D augmented reality, and specializes in two key areas: People Occlusion and Motion Capture. Prior to RealityKit, ARKit and SceneKit would place an object on a table, for example, but it was overlaid onto the scene; the plane was quasi-‘virtual’ and couldn’t identify what else was going on.

Detailed overview of spaCy: the NLP library built for production

In this article, I’ll show you what spaCy is, what makes it special, and how you can use it for NLP tasks. “SpaCy is an Industrial-Strength Natural Language Processing library” — spaCy.iospaCy is a fairly new library to join the NLP world. In this section, I’ll demonstrate how to perform basic NLP tasks with spaCy using practical examples.

The Helpful Bystander: Current Evidence from CCTV-Captured Public Conflicts

The Helpful Bystander: Current Evidence from CCTV-Captured Public Conflicts

Taken together, these data offer compelling evidence that bystander intervention is the norm in public space conflicts. Addressing the question of bystander helpfulness with CCTV video data, Levine, Best and Taylor (2011) assessed the de-escalatory and escalatory actions of bystanders across 42 public assaults. With evidence now suggesting that intervention is helpful from the perspective of the victim, the next question is whether such behaviour is potentially dangerous for the bystander.

Why Medium Sucks

Why Medium Sucks

In the last couple weeks, there’s been a lot of backlash against Medium in response to the infamous “Paywall”. In the email, Oleg explains how Medium strong-armed the non-profit, eventually causing them to leave the platform. For those wondering why the import tool doesn’t work for my blog, here’s what Medium has to say.

Physicists Debate Hawking’s Idea That the Universe Had No Beginning

Physicists Debate Hawking’s Idea That the Universe Had No Beginning

The Big Bang theory, for instance — pioneered 50 years before Hawking’s lecture by the Belgian physicist and Catholic priest Georges Lemaître, who later served as president of the Vatican’s academy of sciences — rewinds the expansion of the universe back to a hot, dense bundle of energy. In 1980, the year before Hawking’s talk, the cosmologist Alan Guth realized that the Big Bang’s problems could be fixed with an add-on: an initial, exponential growth spurt known as cosmic inflation, which would have rendered the universe huge, smooth and flat before gravity had a chance to wreck it. Likewise, Hartle and Hawking expressed the wave function of the universe — which describes its likely states — as the sum of all possible ways that it might have smoothly expanded from a point.

India reportedly orders Uber and rival Ola to electrify 40% of fleets by 2026

India reportedly orders Uber and rival Ola to electrify 40% of fleets by 2026

India orders Uber and rival Ola to electrify 40% of fleets by is doubling down on its push to replace gasoline and diesel vehicles on its streets with environmentally friendly electric cars. The government plans to order ride-hailing firms such as Uber and Ola, that operate hundreds of thousands of cars in the nation, to convert 40% of their fleets to electric by April 2026, Reuters reported today. India’s electric push will spell new frustration for Uber, which is already struggling to fight back against Ola, its local rival and the market leader in ride-hailing space in the country.

Mark Twain’s Portfolio

Mark Twain’s Portfolio

If it was soon after this chance encounter with the operations of United Fruit that Clemens and Rogers chose to invest in the company, that investment surely paid off, but so far as I can tell, they never discussed it, as they did many of their other mutual ventures. One can see Twain’s investment in United Fruit as both an acknowledgment of his own futility – an admission that his anti-imperialist writings weren’t making a damn bit of difference – and a clever way of contriving to make his political enemies subsidize his dissent. Perhaps in part because he could count on the equivalent of $50,000-$60,000 a year from his United Fruit shares (among many other investments), Twain was finally free, in the final decade of his life, from having to publish and lecture in order to sustain himself and his household.

When Grown-Ups Get Caught in Teens’ AirDrop Crossfire

When Grown-Ups Get Caught in Teens’ AirDrop Crossfire

Anyone who has accidentally left their AirDrop settings open around a group of teens is likely familiar with the deluge of memes, selfies, and notes that arrives so quickly it can often freeze your phone. “Another day another group of french teens trying to AirDrop me memes on the subway,” one woman tweeted. It works like this: Once there’s a critical mass of people around, usually enough so that it’s not immediately clear who an AirDrop came from, teens start dropping photos, memes, selfies, and more to every open phone around.
