Linux 3.3: Finally a little good news for bufferbloat
While I was out chasing computer history last week, the Linux 3.3 kernel was released. And a very interesting release it is, though not for its vaunted re-inclusion of certain Android kernel hacks.

Computed goto for efficient dispatch tables
Recently, while idly browsing through the source code of Python, I came upon an interesting comment in the bytecode VM implementation ( Python/ceval.c ) about using the computed gotos extension of GCC [1] . Driven by curiosity, I decided to code a simple example to evaluate the difference between using a computed goto…
