FAQ

 

Q. What's the meaning of B2R2?

B2R2 is a binary analysis framework, thus, the name is related to "binary" and "reversing". In fact, both "B" and "2" stand for binary, and "R" means reversing. Originally, the name of our framework was B2-R2, which was named after R2-D2, a famous fictional robot appeared in the Star Wars. However, we decided to omit the dash (-) as .NET does not allow it in identifiers (or namespaces) anyways.

Q. Does the logo have any special meaning?

Yes, it is inspired by Bagua. The two robots facing each other at the center of the logo resembles the Tai Chi symbol of Bagua. In Taoism, every object in the universe is considered to have their own energy (or force; to use the Star Wars terminology). The energy can be either negative or positive, which is called Yin and Yang, respectively. The concept of Yin and Yang is strikingly similar to "binary", because two seemingly opposite binary values (0 and 1) can form any computations that a computer can perform. The repeated B2R2 letters appeared in the logo also represent Yin and Yang (or binary) as its color alternates.
