    The story does not tell us how Linus Torvalds responded to the NSA, but I’m guessing he told them he wouldn’t be able to inject backdoors even if he wanted to, since the source code is open, and all changes to it are reviewed by many independent people.

    Yeah I’m guessing the answer would be more colorful based on the historical data we have

    Years ago there was a commit to the Linux kernal that strangly had no author. This got some attention of several of the developers.

    Looking into the code that had to deal with network transmission. there was a section that if you tried to get network access in a unusual way had a check that was written something like this.

    If (usr_permission = ROOT) … Instead of If (usr_permission == ROOT) …

    The first giving the user root if invoked and the second checking to see if the user was root.

    It’s widely thought this was the NSA or some other intelligence agency trying to backdoor lin Linux.

    Circa 1975, IBM proposed the cipher now called DES, the Data Encryption Standard. It became a worldwide standard for secret key encryption. As IBM originally designed it, DES had a 64-bit key. The National Security Agency (NSA) required that the key be reduced from 64 bits to 56 bits, with the other 8 bits used as a checksum. This made no sense. If a checksum were really needed, then the key could be increased from 64 to 72 bits. It was widely believed that the real reason the NSA made this demand was that it knew how to crack messages using a 56-bit key, but not messages using a 64-bit key. This proved to be true.

    I somehow misread that as NBA, and was very confused what basketball had to do with OS backdoors

    NSA makes

    WAY more sense

      A OS backdoor is very simular to a backdoor cut, which allows a player to sneak behind defenders when they are focused on the ball or player with a ball.

      NBA coaches have taken inspiration from many different places to perfect their plays. Computer security is just another step.
