Facebook’s dating app will let you list your secret crushes (4 minute read)
Facebook’s new dating app, which is currently only in a testing phase in a few select countries, has a new feature which will let users list up to nine ‘secret crushes’ from their friends list. If one of their friends also lists them as a secret crush, Facebook will send a notification to both users and match them. Facebook Dating usually avoids listing friends as potential matches. While there seems to be no method of monetization during its testing phase, there is big money in the dating app marketplace. Analysts predict that the dating app industry could be worth $12 billion by 2020. The Match Group, who owns Tinder, OkCupid, Match.com, and many other dating sites, brought in $1.7 billion last year from memberships, advertising, and premium features.

McDonald’s deploys 700 AI-powered menu boards (5 minute read)

Going forward, McDonald’s will be deploying AI-powered menu boards at 700 restaurants. The menu boards will use AI to suggest and upsell products based on trending items, the time of day, and the weather. These menus will eventually be added to apps and kiosks. There is pressure from customers and advocacy groups for McDonald’s to introduce a plant-based meat option, similar to Burger King’s new Impossible Whopper, which will be available country-wide by the end of 2019.

A Conspiracy To Kill IE6 (10 minute read)
A bug in Internet Explorer 6 made it try to run code that it couldn’t run, causing the browser to either get stuck in a recursion loop or make it crash into the blue screen of death. This only happened in IE6 and it caused many problems for web developers as they had to make their sites compatible with the browser. A team of developers at YouTube decided that the best way to fix the issue was to threaten to drop support for the browser so that more users would upgrade, eventually making support for the browser unnecessary. Using special privileges, without YouTube’s official permission, they inserted a banner available only for IE6 users that stated that YouTube was going to stop supporting development for the browser and that users should upgrade. The tactic was successful, and eventually, upper management made the deprecation of the browser into real policy.
