In October 2011, Apple added the emoji keyboard to iOS as an international keyboard. Since then, digital language has evolved such that nearly half of comments and captions on Instagram contain emoji characters. And earlier this week, Instagram also added support for emoji characters in hashtags, which allows people to tag and search content with their favorite emoji #.

In addition to looking for evidence of time travelers online, the researchers also reached out to any potential time travelers directly by writing a post on an online message board asking people from the future to tweet using one of two pre-specified hashtags before a certain date that had already occurred. The hashtags (#ICanChangeThePast2 and #ICannotChangeThePast2) were aimed at letting time travelers tell the researchers about the nature of time travel and whether actions taken while traveling in the past can change events in the future.

in a quest to produce the ultimate chair, designer jan habraken and his team at formnation developed chairgenics as a matter of scientific inquiry: if the chair had DNA, what might its descendants look like; and in a race for survival of the fittest, which combination of elements approaches genetic perfection? could modern technology breed the perfect chair? in setting up parameters for the technical hypothesis, formnation considered the genetic makeup of chairs in terms of ergonomics, durability, construction, costs and aesthetics; assigning a 1-10 value for each piece of furniture.

the list of tweets meant to show off Twitter’s success pointed out some of the sadder aspects of human nature.

Edward Chen listed real tweets that help differentiate women from men, and nobody came out looking good. Not women, not men, and not Twitter for looking for gender in such stereotypical places; and for missing some of the sad ironies of the gender signifiers it pointed to with an implied, “Eureka! I’ve found it!”

it's increasingly common for a city to have several centres performing different functions.

D'Acci's new model is designed to cope with this increased complexity. His idea is to calculate the benefit of a given location to a resident, taking into account the effect of all the city's various amenities.Having done that, he calculates locations of equal benefit, connecting them with so-called "isobenefit lines".

That gives a simple and immediate visual representation of the structure of the city in terms of the benefits it offers.

"It appears that Pennsylvania's new strict photo ID requirement may be in effect a racially discriminatory voting procedure," Tamara Manik-Perlman, Azavea's spacial data analyst, wrote in a recently published blog post.

But she admitted that the findings are limited in scope because the analysis is confined to the city of Philadelphia, the only geographic area for which Azavea has all the relevant datasets.

The 33-year-old wrote a program to crawl the Web and download menus from New York eateries. It took her down a rabbit hole of restaurant exploration. She didn’t figure out the perfectly average spot, but she learned that there are 173 different burgers to order in the West Village—but 363 in the East Village, and at lower prices.
