More Sammy in Baja!

The Baja 1000 started this morning. I snagged a couple of pics out of the Off-Road.com photo gallery, they show the H2 waiting for the race to start in Ensenada on contingency row.

I’ll be following the coverage on Off-Road.com and will post anything interesting on Sam and his team as it comes by.

Hall H2 on contingency row in Ensenada

Wilbur, Lisa, Jake and Levi are going to be in town for the weekend, I’ll have plenty more pics to fill up the site.

These are my links for July 20th through July 24th:

The language of choice - Propositional logic was discovered by Stoics around 300 B.C., only to be abandoned in later antiquity and rebuilt in the 19th century by George Boole’s successors. One of them, Charles Peirce, saw its significance for what we now call logic circuits, yet that discovery too was forgotten until the 1930s. In the ’50s John McCarthy invented conditional expressions, casting the logic into the form we’ll study here; then in 1986 Randal Bryant repeated one of McCarthy’s constructions with a crucial tweak that made his report “for many years the most cited paper in all of computer science, because it revolutionized the data structures used to represent Boolean functions” (Knuth).1 Let’s explore and code up some of this heritage of millennia, and bring it to bear on a suitable challenge: playing tic-tac-toe.
Then we’ll tackle a task that’s a little more practical: verifying a carry-lookahead adder circuit. Supposedly logic gets used all the time for all kinds of serious work, but for such you’ll have to consult the serious authors; what I can say myself, from working out the code to follow, is that the subject offers a fun playground plus the most primitive form of the pun between meaning and mechanism.
