How does Facebook know what to show to you? How does it make predictions and guesses your interest? Some of you might be having a rough idea that Facebook’s algorithms keep tracking your activity and user-interactions, but what’s the real deal? To answer these question, a free and open source tool named Data Selfie is here. It’s basically a Chrome extension that tracks you while you’re using Facebook and shows you your own data traces. It further shows how Facebook’s machine learning algorithms use your data to know more about you. How does Data Selfie work? To be precise, Data Selfie records your clicks in the newsfeed, clicks on external links in the newsfeed, time spend on posts and the particular information of those posts, things you type and post, and the overall time devoted t
After two years of hard work and research, Google has successfully broken SHA-1 encryption (Nine quintillion (9,223,372,036,854,775,808) SHA1 computations in total!). The security researchers have been able to achieve the first real-world collision attack against this popular hashing functi on. Before going into the details of the demise of this building block of web encryption, let’s tell you a little about SHA-1 Encryption. What is SHA-1? What does it do? SHA-1 Encryption stands for Secure Hash Algorithm. A hash is a unique code that’s based on some data input. When a person creates a password, it’s “hashed” and stored by the server. When you type a password, it’s hashed again and matched with original hash. In simpler language, SHA-1 generates a digital fingerprint of a file that al

This new feature in Messenger will let the users stick reaction emojis to the messages in conversations. They’ll be able to click on a button next to the text to bring up different reactions. Apart from the six reactions for Facebook posts, the Messenger reactions will also have a dislike or thumbs down button. Image: TechCrunch
