Programmer’s Day is celebrated on the 256th day of the year, and this year, it’s on Wednesday, September 13. This number is important in the binary space, the mathematical foundations that computer science is built on. Computer values are stored in bits, and 8 bits form a byte. With all its binary combinations, a single byte can store amounts from 0–255, which results in 256 unique values total. In honor of this, we’ve come up with a mega-list of 256 reasons to celebrate. They’re packed into 16 categories (2 bytes) of size 16. Finally, in honor of the ‘C’ language, our values are zero-indexed. Of course, with the long history of programming comes a road filled with many revolutions that have changed the way we live. Here are a number of facts that show the magnitude of its impact on our everyday lives. 0. Programming is a top career field.
