Co-routines as an alternative to state machines (2009)

Another, much more elegant approach, is to write the function recursively. A recursive function employs the machine stack used to implicitly implement…

Interactive Programming in C
I’m a huge fan of interactive programming (see: JavaScript , Java , Lisp , Clojure ). That is, modifying and extending a program while it’s running. For certain kinds of non-batch applications, it takes much of the tedium out of testing and tweaking during development. Until last week I didn’t know how to apply…

The Lucky 13 attack against CBC in TLS had just been published and I had spent most of January writing patches for OpenSSL and NSS to implement constant-time CBC decoding.
