USB condoms (Int3)

USB condoms (Int3)

Have you ever plugged your phone into a strange USB port because you really needed a charge and thought: "Gee who could be stealing my data?". We all have needs and sometimes you just need to charge your phone. "Any port in a storm" as the

Antivirus could make your computer more vulnerable (CSO Online)

Since June, researchers have found and reported several dozen serious flaws in antivirus products from vendors such as Kaspersky Lab, ESET, Avast, AVG Technologies, Intel Security (formerly McAfee) and Malwarebytes. Many of those vulnerabilities would have allowed attackers to remotely execute malicious code on computers, to abuse the functionality of

The architecture of a street level panopticon (Dia Kayyali, 32c3)

Street level surveillance technology, such as surveillance cameras and iris scanners, is now a pervasive part of the daily lives of city dwellers, with disastrous consequences for freedom of expression. This talk will cover what kind of street level technology we’re seeing, how it’s spreading, and who’s

Weird, Rare Clouds and the Physics Behind Them (Wired)

In August, we posted a photograph of some odd, rare clouds known as Morning Glory clouds without providing an explanation for how they form. In response to reader interest, we followed up with meteorologist Roger Smith of the University of Munich, who has studied their formation. “Over the years we’

Are Christmas Lights in Series or Parallel? (Wired)

Why don’t your Christmas lights work? Sadly, in the event of a string of lights going out on your tree, replacing the strand is usually the best option. It’s pretty difficult to find that one bulb that’s causing the problem. However, this is a great time to

The Secret Ingredient In Your Orange Juice (Food Renegade)

The Secret Ingredient In Your Orange Juice (Food Renegade)

Do you buy orange juice at the store? If you do, I’m sure you’re careful to buy the kind that’s 100% juice and not made from concentrate. After all, that’s the healthier kind, right? The more natural kind? The kind without any additives? The kind that’

Why Facebook's internet.org in India ain't be a charity (Tech in Asia)

[The aim of the project is] to capture the poor and the needy for free inside, so they could be hooked on this free cocaine of chat and profiles forever; and not discover the actual internet that lies outside these walls. So the real internet outside, where other sites that

Basic income: how Finland plans to implement the first nation-wide project in the EU (Finland Politics)

The Finnish Social Insurance Institution (KELA) has given some preliminary elements concerning Finland’s plan to experiment and then generalize the implementation of a basic income in the country. In its final version, the basic income would replace other benefits people currently receive, and would therefore be rather high, as

Natural nuclear reactors, with pulsed activity (iAfrikan)

Natural nuclear reactors, with pulsed activity (iAfrikan)

Nuclear scientists at the Pierrelatte uranium enrichment plant in south-east France noticed a strange deficit in the amount of uranium-235 they were processing in June 1972. That’s a serious problem in a uranium enrichment plant where every gram of fissionable material has to be carefully accounted for. (...) Physicists soon

How Friendships Change in Adulthood (The Atlantic)

How Friendships Change in Adulthood (The Atlantic)

Friendships are unique relationships because unlike family relationships, we choose to enter into them. And unlike other voluntary bonds, like marriages and romantic relationships, they lack a formal structure. You wouldn’t go months without speaking to or seeing your significant other (hopefully), but you might go that long without

Why You Can Never Tune a Piano (Open Culture)

Why You Can Never Tune a Piano (Open Culture)

Grab a cup of coffee, put on your thinking cap, and start working through this newly-released video from Minute Physics, which explains why guitars, violins and other instruments can be tuned to a tee. But when it comes to pianos, it's an entirely differently story, a mathematical impossibility.

Stop Googling. Let’s Talk (NY Times)

College students tell me they know how to look someone in the eye and type on their phones at the same time, their split attention undetected. They say it’s a skill they mastered in middle school when they wanted to text in class without getting caught. Now they use

Why Russia has the world's most beautiful bus stops (The Guardian)

Architects may have felt creatively stifled in the old Soviet empire – but there was one place where their imaginations were encouraged to run riot: the bus stop. https://www.theguardian.com/artanddesign/2015/sep/02/soviet-superpower-why-russia-has-the-worlds-most-beautiful-bus-stops (discussion on HN: https://news.ycombinator.com/item?id=10186954 praising the subway stations

Dalí, Escher, and Magritte Inspire a Stunning Video Game (Vice)

Dalí, Escher, and Magritte Inspire a Stunning Video Game (Vice)

Surrealism and somnambulism are the themes behind a new video game inspired, in part, by the topsy-turvy aesthetics of Dutch artist M.C. Escher, and the unique stylings of modern masters Salvador Dalí and René Magritte. A major hallmark of surrealism has always been the blurring of the lines between

Meet the electric life forms that live on pure energy (New Scientist)

Unlike any other life on Earth, these extraordinary bacteria use energy in its purest form – they eat and breathe electrons – and they are everywhere. https://www.newscientist.com/article/dn25894-meet-the-electric-life-forms-that-live-on-pure-energy/

Is Advertising Morally Justifiable? The Importance of Protecting Our Attention (Thomas Wells, ABC)

Advertising is a natural resource extraction industry, like a fishery. Its business is the harvest and sale of human attention. We are the fish and we are not consulted. Two problems result from this. The solution to both requires legal recognition of the property rights of human beings over our

The Sixth Sense You Didn’t Know You Had (Discover Magazine)

Ever fancied having a superpower? Something you can call upon when you need it, to hand you extra information about the world? OK, it’s not X-ray vision, but your eyes do have abilities that you might not be aware of. We are all familiar with color and brightness, but

The Faces of Ultraviolet (Slate)

The Faces of Ultraviolet (Slate)

I spend a lot of time thinking about how narrowly we see the Universe. Our eyes perceive the narrowest slice of the electromagnetic spectrum, the huge range of flavor lights comes in. Radio waves, infrared, ultraviolet, X-rays, gamma rays—they make visible light, from blue to red, seem hopelessly parochial.
