Square’s Head of Software Jesse Dorogusker explained

Square announces the Register, a $999 point-of-sale device for larger businesses

that while the company’s existing products incorporate existing hardware (the Square Stand, for example, turns an iPad into a POS stand), the Square Register is "totally integrated — our hardware, our software, all in the box, all by Square.”

CEO Jack Dorsey added that the Register is meant to address concerns from larger sellers who are using Square or considering about using it. For one thing, he said some businesses felt the Stand was "very consumer-focused,” so they wanted something "more professional.”

More specifically, Dorsey said the Register solves a big pain point by coming with separate screens for the buyer and seller. The Square team thought it was "clever” to design the Stand to swivel back-and-forth ("and it is quite clever”), but larger sellers wanted separate displays, allowing the customer to see each product as they’re being rung up.

The customer display also allows businesses to show off their imagery and branding. It’s detachable to accommodate different countertops. And it supports tap-to-pay, allowing customers to pay with their phone or watch without having to pass it over to the cashier.

Other features include Ethernet and offline support, so that businesses without good WiFi (say at a concert venue, or in the basement of a mall) can still use it without worrying about connectivity, and a five-port USB hub, so that the Register can be connected to other devices.

 

Square Register

This isn’t necessarily going to replace the Stand or Square’s other hardware. Instead, Dorogusker said this gives larger sellers "two great choices,” and he added that the real goal is to replace "the giant beige and gray boxes that are out there in the world.”

As for whether Square is shifting away from supporting smaller businesses, Dorsey said they’ll "always be a part of our growth plan and always who we serve.” At the same time, he said the company decided early on that it wasn’t just going to focus on small and independent retailers: "The problem with that is, they want to grow … We can’t be a service that says, ‘Oh, you’re too big for us.'”

The Square Register will cost $999, plus a transaction fee of 2.5 percent and 10 cents per transaction. Dorogusker acknowledged that might sound a little pricey ("You wouldn’t consider $999 an impulse purchase”) but he said larger retailers are already spending thousands of dollars on point-of-sale hardware. Plus, the price is lower than buying two comparable iPads. Square is also offering a financing option where businesses pay $49 a month for 24 months.

Ben & Jerry’s Ice Cream is already using the Square Register in select locations. And as part of the launch, Square is hosting a pop-up with Top Dawg Entertainment at the Square Showroom in New York City.

10 Amazing Health Benefits

Nutritionists have identified a group of foods that provide amazing health benefits. Dubbed ‘superfoods’, this group provide nutrients that normal food groups could only dream of.

There’s no strict definition of a superfood. But what scientists do know is that these foods are full of more than just essential vitamins and minerals. Many of these foods also include a healthy dose of antioxidants and polyphenols.

Some science suggests that people who regularly consume these foods reduce their risk of certain diseases. Other evidence suggests that they help prolong life. Whatever it is that these superfoods do, many of the people who consume them regularly are often healthier than those who ignore them.

Some of these superfoods include foods like kale. Others are fruits like acai and blueberries. But one of the most essential superfoods is Kerson fruit.

What Is Kerson Fruit?
Kerson fruit grows on trees. The fruit resembles a cherry and has a tart flavor. Kerson fruit is not always known by this name. It is also referred to as the Panama berry, the Jamaican cherry and the Singapore cherry. If you buy them from a Spanish grocer, the fruit would be called a yamanza, memizo or bolania.

The trees grow all around the world. However, they primarily grow in warm climates. These fruit can be found throughout the Caribbean and Mexico. It grows as far south as South America. It is also found in southern Asia. It grows in countries like India, Indonesia and the Philippines.

There are many amazing health benefits of Kerson fruit. The following list contains only ten out of dozens of essential properties of this superfood.

Antibacterial Properties
The Kerson fruit offers antibacterial properties that are beneficial to anyone. These antibacterial properties help kill harmful bacteria while promoting good bacterial. This can help ward off infections and illnesses.

Low Blood Pressure
Drinking tea made from the leaves of this tree can help relieve low blood pressure. Low blood pressure often occurs when blood is unable to flow around the body at a normal rate. Low blood pressure can be dangerous and it often results in poor circulation.

Kerson fruit leaves help by providing nitric oxide. This helps improve blood flow by relaxing your blood vessels.

Pain Relief
The tea that helps improve your blood pressure can also help relieve mild pain. It works by blocking pain receptors. This is similar to how opiates work. The benefit of drinking tea is that you do not have the side effects associated with medication.

Relieves Inflammation
The tea made from the leaves of the Kerson tree also has anti-inflammatory properties. This is great for treating inflammation anywhere in the body. It can also help relieve swelling and fevers.

Provides Antioxidants
As a superfood, Kerson fruit offers plenty of antioxidants. What makes this fruit special is that it offers many of the antioxidants found in green tea.

There are around 24 different phenolic and flavonoid compounds found in Kerson fruit. This is great news for anyone who wants the benefits of green tea without the caffeine.

Relieves Headaches
Both the fruit and tea from the leaves are known for providing relief from headaches. It helps by providing mild pain relief. It also reduces the inflammation associated with headaches.

Avoid Cancer
One of the biggest reasons why many people flock to superfoods is to prevent cancer. There are many properties in superfoods that may help people avoid cancer. The Kerson fruit is no exception to this.

Some science suggests that Kerson fruit and other superfoods have properties that prevent cancer and will spare you the need to start a claims process in case of medical complications. Although there is no conclusive evidence, eating these fruits seems like a safe and tasty way to keep your body healthy.

Works as a Multi-Vitamin
Besides to the 24 antioxidants the fruit provides, the Kerson fruit offers all the benefits of a great multi-vitamin. The Kerson fruit has plenty of fiber. It also has a balanced amount of carbohydrates, protein, phosphorus and calcium.

In addition to these macronutrients, Kerson fruit also offers B-Vitamins, iron, and vitamin C. All of these have serious health benefits and can improve your quality of life.

Treats Gout
One of the most celebrated aspects of Kerson fruit is how it treats gout. It works to relieve the pain that often comes with the disease. Some research suggests that eating 10 cherries three times daily will help treat the pain.

Relieves Cramps
The pain blockers also work to relieve abdominal cramps. The tea created from Kerson fruit leaves constitutes a natural home remedy for stomach cramps.

The Kerson fruit tree is a great superfood with plenty of beneficial properties. To try it for yourself, you can buy fresh fruit from both Asian and Latin supermarkets. You can also find it online in health supplement shops.

Google’s cord cutter app YouTube TV reaches 2 million downloads

Approximately 2 million people have installed the YouTube TV app, Google’s live TV service aimed at a younger generation of cord cutters, as well as those who never signed up for traditional pay TV in the first place. That download figure comes from app store analytics firms Sensor Tower and App Annie, which both also noted that installs are evenly split between iOS and Android devices book hotel hk.

Of course, 2 million downloads doesn’t necessarily translate into subscribers — many users may have simply installed the app out of curiosity; others could be on free trials that never convert to paid subscriptions.

Still, it’s a number that should give YouTube TV competitors — in particular, telco rivals — pause. YouTube TV is the youngest arrival in the over-the-top live TV space, and it’s growing rapidly.

Sensor Tower said that YouTube TV added about 700,000 new installs of its app since its announcement last week that it was entering several new U.S. markets, tripling its footprint DDoS Attack.

Yes, that’s right — YouTube TV has 2 million installs and isn’t even available across all of the U.S. at this point.

That’s a promising start for a newcomer in this race, even if many of those are still trial customers Serviced apartment Hong Kong.

Using the hashtags #OpKKK and #HoodsOff, Anonymous "unhooded" alleged Klan members online, and provided links to social media accounts which contained their photos, addresses, phone numbers, ages, workplaces, and photos of their children.

Most Twitter users appeared supportive of Anonymous.


We would never post pictures of their kids, or where they live. We don't out any small person who has radical right views; only if they are hiding behind anonymity to do something really loathsome”

"I daresay that @KuKluxKlanUSA will remember, remember, remember the 16th of November. Bravo, Anonymous, Bravo. #oppKKK #hoodsoff," wrote Carlos Larkin.

After back-and-forth taunting, in which the KKK wrote "We are continuing to read Anonymous threats with much amusement" and "I thought you Anons were all about free speech. Cowards!", Anonymous gained access to the KKK website and took over its Twitter account.

The most recent tweet from the hacked @KuKluxKlanUSA account was on Monday evening, showing a unicorn and rainbow in front of a sunset scene.

Responding to criticism about violating free speech, Anonymous released this statement:

"We are not attacking you because of what you believe in, as we fight for freedom of speech. We are attacking you because of your threats to use lethal attacks against us at the Ferguson protests… The Ku Klux Klan is a terrorist group. The blood of thousands of human beings are on the hands of the Klansmen."

he altered the course of classical music forever.

"It would be inconceivable,” said Schoenberg, "to attack the heroes who make daring flights over the ocean or to the North Pole, for their achievement is obvious to everyone. But although experience has shown that many a pioneer trod his path [with] absolute certainty at a time when he was still held to be wandering half-demented, most people invariably turn against those who strike out into unknown regions of the spirit… New music is never beautiful on first acquaintance.” Often forced onto the defensive like this, Schoenberg plunged fearlessly – and often beautifully – into the unknown, shattering the seemingly unbreakable rules of Western tonality that had prevailed for centuries. In reimagining harmony in so-called ‘tone rows’ he altered the course of classical music forever.じいあぉあ

His breakthrough work was The Firebird, produced in 1900 by Diaghilev’s Les Ballets Russes; thirteen years later, a full-scale riot legendarily broke out at the premiere of The Rite of Spring, his ballet of pagan sacrifice (which historian Barbara Tuchman aptly describes as "the 20th Century incarnate"). The New Yorker’s music critic Alex Ross masterfully captures the work’s ominous energy, it raw, spooky power and explains how this is achieved both harmonically and rhythmically. "looselyYou have these two chords slammed together," Ross explains. "These are two adjacent chords. They're dissonant. They're being jammed together. And that's a harsh sound, and he keeps insisting on it. That chord repeats and repeats and repeats, pounding away." Rhythmically, Ross says, "It seems as though at first he's just going to have this regular pulse. But then these accents start landing in unexpected places, and you can't quite get the pattern of it…It's as if you're in a boxing ring, and this sort of brilliant fighter is coming at you from all directions with these jabs."jiiiaser

Rarely did films show sexual act

I was 10 when I saw my first film, and had already snuck a look in the back of my mother's Home Doctor book and was shocked and intrigued by the pictures I found there.HKUE amec

Other children had been told by friends, while the more cavalier characters in class might have encountered pornography in magazines or in films. As sex education films often glossed over penetration into a sanitised narrative, smirks would accompany these films just as much as grimaces.針灸

The laughter didn't stop when dainty cartoons of the human anatomy showed what happened inside us, rather than between us. But occasionally, some films would show very progressive material. A few memorable films showed the experience of childbirth, prompting gasps and stunned silences and, in some cases, fainting.

Rarely did films show sexual acts. Dr Martin Cole's 1971 film Growing Up, is one of the few that broke with convention, showing masturbation and intercourse acted out by real people. By attempting to dispel the shame and guilt that clouded sexual behaviour, he received some positive feedback from teachers and pupils.

Novelty value

But the film also triggered national controversy. It was banned by Birmingham City Council and criticised heavily by the Sun newspaper.

Whatever their content, educational videos still had novelty value for children in the 1970s and 1980s. For starters, visual material was rare in schools, and it is easy to forget that televisions at home had only three channels until 1982.

In the 1970s the protagonists became a lot hairier

Sexual images and debate were also less common. There were tighter controls on TV and magazines, and the availability of sexual resources on the internet, both in terms of health and pornography, was still many years away. But these films also had novelty value for teachers.

While obviously saving them the embarrassment of explaining the mechanics of sex to minors, they also brought to their classrooms an engaging new tool. After a class watched a sex education film, and thought about the interesting images and ideas they had encountered, they could then pose questions to their teacher about what they had seen, and healthy debate could be encouraged.

In many cases, this actually happened.

Many would argue that sex education films are needed more than ever today, especially while teenage pregnancies continue to rise, and sex continues to be so prominent in popular culture. 旅遊團

The annals of movie history are filled with clashes.

Battles between executives and directors are nearly always a struggle between commerce and art. Executives want a picture that will maximise box office takings. Anything that might dampen ticket sales can become part of the tussle. Film length is often a major concern as are complexity of plot and whether or not the film has a ‘feel good’ ending that sits well with focus groups.iphone 4 screen protector

The annals of movie history are filled with clashes. Early cuts of Ridley Scott’s classic science-fiction film Blade Runner (1982) infuriated producers who commented that parts of it were dull and confusing. Terry Gilliam had difficulties in 1985 with his picture Brazil, which was 142 minutes long. Although it already had been released outside the US, the president of Universal Pictures ordered a dramatic re-edit for the American market despite objections from Gilliam. After a very public dispute, a longer cut, supervised by Gilliam, was released by the studio – but it failed to drum up much excitement at the box office.designer bags sale

In fact it’s not always the case that final cut is protecting a filmmaker from heartless profit-driven executives riding roughshod over the artistry of filmmakers. Some would take the view that audiences might have benefitted from a little studio-ordered editing of films from at least two directors who enjoy final cut privileges: Peter Jackson and Steven Spielberg. Jackson’s recent Hobbit films have been criticised for being overlong – as has Spielberg’s Lincoln in 2012.

The giant bears had been primed to choose their food

The giant bears had been primed to choose their food from various baskets emblazoned with the national flags of the teams, thereby predicting winners.

But moments before the opening game kicked off, the Chengdu research base pulled out of the stunt.

The idea of animals predicting football scores has become a standard publicity stunt for zoos and other organisations.

The most famous example from the last tournament was Paul the octopus, who apparently correctly guessed the winners of games until the semi-final.
Giant panda cubs lie in a crib at Chengdu Research Base of Giant Panda Breeding in Chengdu, Sichuan province, September 23, 2013 Panda cubs would have indicated the winners through their choice of food container

This year, a whole variety of animals across the world are being touted as the successor to Paul.

The pandas' attempt to emulate Paul had been eagerly anticipated on social media SEO Hong Kong.

But late on Thursday, the Chengdu facility said it had been ordered to stop the stunt.

"The predictions have been halted by the authorities," a spokesman told the AFP news agency without giving any details.

However, the Chinese newspaper Global Times quoted a spokesman from the research enclosure as denying the authorities had stepped in.

The spokesman said the stunt had been cancelled by the research centre because it would have harmed the pandas by requiring too much contact with humans dermes vs medilase.

The other has evolved circular suckers on the end of each leg bristle

The micro-scale study revealed how bristles on male beetles' legs attach to females. 百合空间

Tiny suckers on these bristles stick to the females' bodies. miewe

As well as shedding light on evolution at the very tiny scale, understanding this could inspire the design of devices for underwater attachment in engineering.

The results are published in the Royal Society journal Interface. 浪美心的blog

The team, led by Dr Kai-Jung Chi from National Chung Hsing University in Taiwan, directly measured the gripping force of the "attachment devices" on the leg bristles of two diving beetle species.

Microscopic images reveal that one of the species they studied - a more primitive insect - has a spatula-like attachment. ぶあすえ

The retired field marshal overthrew President

The former army chief said he wanted "freedom" and "social justice", echoing the slogan of the 2011 revolution.

Mr Sisi spoke after election officials announced that he had received 96.9% of the vote and his sole challenger, left-winger Hamdeen Sabahi, only 3.1%.

The retired field marshal overthrew President Mohammed Morsi last July.

He has since been locked in a battle with Mr Morsi's Muslim Brotherhood, which urged a boycott of what it called "the election of blood".

Liberal and secular activists, including the 6 April youth movement which was prominent in the 2011 revolution that ousted Hosni Mubarak, also shunned the poll in protest at the curtailing of civil rights.
'Historic day'

Some journalists and government officials burst into applause and started dancing after the final results of the election were announced at a news conference in Cairo on Tuesday.

Thousands of Sisi supporters also celebrated in the capital's famous Tahrir Square, cheering, singing songs and setting off fireworks.

Yet Nhong Huu Ling, just south-west of Udon Thani, now calls itself a "red village", as do thousands of others in the region, which is the heartland of support for the governing Pheu Thai party of Prime Minister Yingluck Shinawatra.

The declaration is little more than a symbolic statement of allegiance to the wider so-called red shirt movement that loosely incorporates the government's mass support base. 雪纖瘦

Villagers get together to share ideas on practical issues, like supporting small businesses or controlling illegal drug use. They also discuss politics. And these days, there is a lot to discuss.

On the day I visited the village head's house - with a giant-sized poster of former Prime Minister Thaksin Shinawatra in ceremonial robes covering one wall - there was a heated discussion about the comments being made by the anti-government protest movement in Bangkok, in particular the call for the entire Shinawatra family to be forced to leave the country - a call that at one point had reduced Ms Yingluck to tears. 排毒方法

It looked, from the outside, like a heart attack.

In 1986, a 44-year-old woman was admitted to Massachusetts General Hospital. She felt fine all day, but in the afternoon she developed extreme crushing pain in her chest, radiating through her left arm. It's a classic sign of a heart attack, but the puzzling thing was that she didn't suffer from coronary heart disesase. There was no life-threatening clot in the arteries surrounding the heart.

It looked, from the outside, like a heart attack, but it wasn't. Describing the unusual case in the New England Journal of Medicine, Thomas Ryan, and John Fallon suggest the apparent damage to the heart muscle was emotional rather than physiological. Earlier that day, she had been informed that her 17-year-old son had committed suicide.

Could the woman have suffered from a broken heart? The answer, it turned out, was already hiding in plain sight. The Massachusetts case was surprising to doctors – but it wasn’t news to everybody.

For many years, doctors scorned the idea of a relationship between psychology and physiology. In their book Zoobiquity, Kathryn Bowers and Barbara Natterson-Horowitz described this attitude: "Among many physicians, the idea that emotions could cause actual physical events within the architecture of the heart was viewed with nearly the same sideways glance as an interest in healing crystals or homeopathy. Real cardiologists concentrated on real problems you could see: arterial plaque, embolising blood clots, and rupturing aortas. Sensitivity was for psychiatrists."

Despite this, the evidence that extreme emotions can impact the heart goes back decades – only not among humans. It was wildlife biologists and veterinarians who first noticed that extreme emotions can wreak havoc on body physiology. By the mid-20th Century, they noticed that a curious thing happens when an animal experiences a sudden jolt of life-or-death fear. When it's caught by an advancing predator, adrenaline fills the bloodstream to such an extent that the blood almost becomes like a poison, damaging the animal's muscles, including the heart. It’s called "capture myopathy”.

combining marine physiology

A new research study combining marine physiology, neuroscience, pharmacology(药物学), and behavioral psychology has revealed a surprising outcome from increases of carbon dioxide uptake in the oceans: anxious fish. A growing base of scientific evidence has shown that the absorption of human-produced carbon dioxide into the world's oceans is causing surface waters to decline in pH, causing a rise in acidity. This ocean acidification is known to disrupt the growth of shells and skeletons of certain marine animals but other consequences such as behavioral impacts have been largely unknown.
 
In a study published in the journal Proceedings of the Royal Society B (Biological Sciences), scientists at Scripps Institution of Oceanography at UC San Diego and MacEwan University in Edmonton, Canada, have shown for the first time that rising acidity levels increase anxiety in juvenile rockfish, an important commercial species in California. Using a camera-based tracking software system, the researchers compared a control group of rockfish kept in normal seawater to another group in waters with elevated acidity levels matching those projected for the end of the century. They measured each group's preference to swim in light or dark areas of a testing tank, which is a known test for anxiety in fish. The researchers found out that normal juvenile rockfish continuously moved between the light and dark areas of the tank. However, experiments have shown that fish administered with an anxiety-inducing drug (anxiogenic) prefer the darker area and seldom venture into the light. Hence, dark-preference is indicative of increased anxiety in juvenile rockfish.
 
Next, the researchers found that rockfish exposed to acidified ocean conditions for one week also preferred the dark area of the tank, indicating they were significantly more anxious than their normal seawater counterparts. Rockfish exposed to acidified ocean conditions remained anxious even one week after being placed in seawater with normal carbon dioxide levels. Only after the twelfth day in normal seawater did the anxious fish behave like the control group and resumed normal behavior.
 
The researchers say the anxiety is traced to the fish's sensory systems, and specifically "GABAA" (neural gamma-aminobutyric acid type A) receptors, which are also involved in human anxiety levels. Exposure to acidified water leads to changes in the concentrations of ions in the blood (especially chloride and bicarbonate), which reverses the flux of ions through the GABAA receptors. The end result is a change in neuronal activity that is reflected in the altered behavioral responses described in this study.
 
"These results are novel and thought-provoking," said Martín Tresguerres, a Scripps marine biologist and study coauthor, "because they reveal a potential negative effect of ocean acidification on fish behavior that can possibly affect normal population dynamics and maybe even affect fisheries."
