When it comes to VR and other simulations, time accuracy could mean either euphoria or you painting the walls a lovely new color, so Facebook invented a new time metric to ensure the former.
When developing a time-sensitive fracture, rigid body, or fluid simulation, accuracy could mean the difference between success or mom’s spaghetti on the floor. Facebook has solved this problem by inventing a new unit of time — spearheaded by a former employee at the company, Christopher Horvath — that helps developers improve time synchronization within one second, which is quite important when it comes to Virtual Reality, among other things.
The ‘flick’ as it is called — derived from ‘frame-tick’ — represents 1/705,600,000 of a second in C++. In comparison, a nanosecond comes in at one billionth of a second, or 1/1,000,000,000. The reason a flick represents this specific amount of time is quite simple. It allows developers divide some of the most common refresh rates for film and VR evenly, without ending up with messy fractions. For example, a single frame at 1/30fps has an exact duration of 23,520,000 flicks, instead of 33,333,333.333… in nanoseconds.
A Facebook spokesperson elaborated on this further:
The humble flick joins the likes of ‘a jiffy’ which represents an indeterminable amount of time, a shake which comes in at 10 nanoseconds, and a microcentury, something that represents around 52 minutes. In South Africa, the amount of time called ‘now-now’ could either mean now or never.
In other Facebook news, the company admitted that it played a key part in ‘corroding democracy’ during the 2016 U. S. election cycle. According to its product manager Samidh Chakrabarti, the platform was supposedly used as a weapon by the Russians to influence American voters, with it recognizing the problem ‘too late’. The company also announced new changes coming to its news feed that should ‘encourage dialog’ between members, deprecating content posted by Pages.
