Here's what a clown learned about male violence by face-painting kids at a picnic

Sanduhruh is a clown who wrote a twitter thread about her experience painting faces at a picnic. When little boys wanted butterflies painted on their faces, the parents objected.

National Rifle Association TV host says his request for North Korea to nuke California was a "joke"

Grant Stinchfield thought his call for North Korea to incinerate millions of human beings was a real knee-slapper. He's sorry some people didn't find it as funny as he did.

“Let's send a note to North Korea that Sacramento changed its name to Guam!," he tweeted.

From The New York Daily News:

Internet users were quick to jump on the cavalier comment as a recommendation that North Korea try to hit a city on the U.S. mainland.

The tweet was also viewed as insensitive to the people of Guam, who recently received guidance about how to avoid being blinded by a potential attack.

Stinchfield told the Daily News Friday afternoon that he is sorry for the remark.

“It was meant as a joke and I regret it,” he said by phone.

Why do porn sites have social media sharing buttons?

On Reddit, the question was asked, "Why do porn sites have social media sharing buttons?" It's a good question!

The Next Web presented some of the most plausible answers:

“Because while it would be immensely embarrassing for you, it’d still be great advertisement for them,” one commenter says. “Realistically, nearly every blog standard CMS framework comes with them on out of the box these days,” another argues. “Most sites probably just don’t turn them off.”

One user suggests that it’s probably there for people who post porn on Tumblr or Reddit — which makes sense, as they are places for embedding images and videos that offer greater anonymity.

Court orders venture capital billionaire to restore access to public beach

Sun Microsystems co-founder Vinod Khosla must open access to a public beach that he'd closed for private use, says a California court.

From The Guardian:

Khosla’s refusal to restore access has made him something of a symbol of the immense wealth in the tech industry and rising income inequality in the region.

Last year, his attorneys claimed that he would open the gate to the beach only if the government paid him $30m, an amount that state officials said was unreasonably high. In October, Khosla also sued two state agencies, accusing the government of using “coercion and harassment” to infringe on his private property rights.

The California coastal commission, established by voters in 1972 to protect public use of the coast, has reported that beachgoers have increasingly complained about private security guards telling them they are trespassing on private property and forcing them to leave the public beaches.

Martin Gardner puzzle: red, white, and blue weights

Here's a good puzzle from Martin Gardner's Mathematical Circus. The book is out of print but used copies are cheap.

Problems involving weights and balance scales have been popular during the past few decades. Here is an unusual one invented by Paul Curry, who is well known in conjuring circles as an amateur magician

You have six weights. One pair is red, one pair white, one pair blue. In each pair one weight is a trifle heavier than the other but otherwise appears to be exactly like its mate. The three heavier weights (one of each color) all weigh the same. This is also true of the three lighter weights. In two separate weighings on a balance scale, how can you identify which is the heavier weight of each pair?

Frixion Erasable Blue Gel Ink Pen ($13, 3 Pack) "So, this pen is not actually marketed as a disappearing ink pen. It’s marketed as a Frixion Pen, and its intention is to be an erasable pen — it’s a normal-looking pen and on the back of the pen is this sort of rubber or plastic nib. And if you write with the pen and you rub the nib over the ink, the ink goes away. But, the true nature of the pen is that it's heat activated. So, if you heat up the ink, it disappears. That could be with the nib that's on the back of the pen or that could be with the flame from a lighter or that could be in a microwave. So, basically, what you have, is you have a pen that writes with ink that you can make disappear with fire. And that is a pretty cool tool to me. … One of the cool things about it is that you can use it sort of as a fun science thing to do with kids because, you don’t necessarily need to use fire.

U.S. embassy employees in Cuba deafened by mysterious sonic weapon

Two employees at the US embassy in Havana have been sent home after suffering hearing loss from a silent "acoustic attack."


The sophisticated device that operated outside the range of audible sound was deployed either inside or outside the residences of US diplomats living in Havana, according to three US officials.

The Cuban government says it had nothing to do with the attack.

From Time:

Cuba employs a state security apparatus that keeps many people under surveillance and U.S. diplomats are among the most closely monitored people on the island. Like virtually all foreign diplomats in Cuba, the victims of the incidents lived in housing owned and maintained by the Cuban government.

However, officials familiar with the probe said investigators were looking into the possibilities that the incidents were carried out by a third country such as Russia, possibly operating without the knowledge of Cuba's formal chain of command.
