Algorithms, in the popular imagination, are mysterious, powerful entities that stand for all the ways technology and modernity both serve our every desire and threaten the values we hold dear.
Meine Hoffnung ist, dass mit Java 8 dieses Problem nicht mehr auftritt. Every time you open Facebook, one of the world’s most influential, controversial, and misunderstood algorithms springs into action.It fueled the stratospheric rise of billion-dollar companies like Zynga and Living Social—only to suck the helium from them a year or two later with a few adjustments to its code, leaving behind empty-pocketed investors and laid-off workers.Facebook’s news feed algorithm can be tweaked to make us happy or sad; it can expose us to new and challenging ideas or insulate us in ideological bubbles.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.He can, however, tell me what it does, and why—and why it’s always changing.He starts, as engineers often do, at the whiteboard. That requires an algorithm: a set of concrete instructions by which a given problem may be solved.Tom Alison is director of engineering for the news feed; he’s in charge of the humans who are in charge of the algorithm.Alison steers me through a maze of cubicles and open minikitchens toward a small conference room, where he promises to demystify the Facebook algorithm’s true nature.Facebook’s algorithm, I learned, isn’t flawed because of some glitch in the system.
