Technically, the linked article is correct that it is something that I like to say, but I stole the phrase from David Schleef (one of the Dirac developers).

I wondered why they used TZCNT instead of BSF. If their algorithm has correctly located the word with the jth bit set, the output of PDEP shouldn't be zero, and these should be equivalent (but BSF doesn't require a dependency on B

You can check for errors with alloca. It returns NULL on failure. You have the same problem as with error checking malloc. On platforms with overcommit (any fork-based UNIX, except maybe Solaris) it doesn't fail at allocation time, it

There are a number of features that make AV1 structurally more suited to real-time implementations than its predecessor, VP9. For example, it does adaptive entropy coding instead of explicitly coding probabilities in the header. That mean

I didn't claim [4] was the solution. I claimed the problem was solvable. One example of how to improve on [4] is to build into browsers the option of automatically searching archive.org whenever you hit a 404.
