Every time you open Facebook, one of the world’s most influential, controversial, and misunderstood algorithms springs into action. It scans and collects everything posted in the past week by each of your friends, everyone you follow, each group you belong to, and every Facebook page you’ve liked. For the average Facebook user, that’s more than 1,500 posts. If you have several hundred friends, it could be as many as 10,000. No one outside Facebook knows for sure how it does this, and no one inside the company will tell you. Facebook through the Years Facebook’s news feed algorithm has shaped not only what we read and how we keep in touch, but how the media frame stories to catch our attention.

The Anatomy of a Forgotten Social Network The study of social networks has gripped computer scientists in recent years. In particular, researchers have focused on a few of the biggest networks that have made their data available, such as some mobile phone networks, Wikipedia and Twitter. But in the rush, one network has been more or less ignored by researchers: Tumblr, a microblogging platform similar to Twitter. So an interesting question is how the network associated with Tumblr is different from the Twitter network. Today we get an answer thanks to the work of Yi Chang and pals at Yahoo Labs in Sunnyvale.

Inside Facebook’s Decision to Blow Up the Like Button Chris Cox wants to mess with Facebook’s secret sauce. By Sarah Frier | January 27, 2016 Photographs by Adam Amengual From The most drastic change to Facebook in years was born a year ago during an off-site at the Four Seasons Silicon Valley, a 10-minute drive from headquarters. Chris Cox, the social network’s chief product officer, led the discussion, asking each of the six executives around the conference room to list the top three projects they were most eager to tackle in 2015.

After the Election: ‘What a Pathetic Thing Is Decadence’ Today is finally Election Day, mercifully. Our tireless politics team is live-blogging events throughout the day and into the night. Over the past several weeks, scores and scores of your emails have poured in, covering a wide array of campaign topics, so here’s one final roundup of your smart opinions and analyses as the polls open this morning. (They’re already closed in Dixville Notch, New Hampshire, the first vote in the nation, and in that tiny hamlet Clinton beat Trump in a landslide, 4-2—a harbinger, we hope.) Most recently we had a roundup of reader reaction to the Comey aftermath, and a new reader makes an interesting point here:

The big myth Facebook needs everyone to believe ( J.J. Alcantara/The Washington Post; iStock) In the middle of January, in a change noticed nowhere but Spain, Facebook added six words to a single dialogue box — and inadvertently stumbled into a tortuous national debate. The dialogue box is part of Facebook’s content-reporting process, the means by which users can request that the social network censor their friends. The six words appeared to invite Spanish users to report on a new category of things: Under the option “it’s inappropriate, it annoys me, or I don’t like it,” Facebook listed Spain’s millennium-old national pastime, bullfighting. The offending dialogue box.

Maybe This is What Life is About – The Mission – Medium From the end to the beginning, people are the point. Yes, the ones you’re going to see today. Yes, the people you are going to see tomorrow. You may write the next Harry Potter and make a ton of money. Then later you will be dead.

We've all heard of think tanks, but many people don't know exactly what think tanks do and what their influence is over public opinion and policies. A think tank is an organization that conducts research and attempts to influence public policy in many different areas including business and finance, economics, education, fiscal policy, defense, security, technology, science, foreign affairs, health and science and political strategy. There are think tanks all over the world, but the United States has by far the most – a whopping 1815 think tanks with 14.66 trillion dollars being poured into these idea factories. Think tanks have a huge influence over public opinion and policy – after all, that is what they are meant to do.

Facebook search tools take aim at Twitter’s relationship with news Facebook is updating its search tool to make it easier for users to find things that interest them among the 2 trillion items archived by the company’s index. The update boasts personalized search suggestions, the ability to search through public posts in addition to those made by friends or family, and a new tool that allows people to view public conversations around news stories. That last item is by far the most interesting — and the one most likely to worry Twitter. Twitter often bills itself as a forum for public conversations. Unless someone makes their entire account private, every 140-characters-or-fewer missive is indexed and can be found by anyone using the service’s search function. You requested someone with a degree in this? *Holds up hand* You requested someone with a degree in this? *Holds up hand* So there are two main schools of Artificial Intelligence — Symbolic and non-symbolic. Symbolic says the best way to make AI is to make an expert AI — e.g. if you want a doctor AI, you feed it medical text books and it answers questions by looking it up in the text book. Non-symbolic says the best way to make AI is to decide that computers are better at understanding in computer, so give the information to the AI and let it turn that in to something it understands. As a bit of an apt aside — consider the Chinese room thought experiment.
