Swissembly is a blog about efficient low-level algorithms for doing stuff, and musings on the ways this has been achieved over the past 50 or so years of computing history.  In other words, what compiled code “should” look like: either because the compiler did a job well-suited to the target architecture, or because a human with a complete grasp of the problem took the time to hand-tweak some code.

Another feature is integrated-circuit hardware peripherals that assist in the development of really neat, compact, fast or otherwise impressive ways of doing stuff with cheap printed circuits.

The official Swissembly coat of arms as featured in the first blog post looks a lot like the official Switzerland coat of arms, but with an exclusive OR instead of a garden-variety, inclusive OR.  (This feature makes the blog more exclusive.)
