  • 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.

  • Read Intermediate Python | Leanpub – This book is intended as a concise intermediate level treatise on the Python programming language. There is a need for this due to the lack of availability of materials for python programmers at this level. The material contained in this book is targeted at the programmer that has been through a beginner level introduction to the Python programming language or that has some experience in a different object oriented programming language such as Java and wants to gain a more in-depth understanding of the Python programming language in a holistic manner. It is not intended as an introductory tutorial for beginners although programmers with some experience in other languages may find the very short tutorial included instructive.

    The book covers only a handful of topics but tries to provide a holistic and in-depth coverage of these topics. It starts with a short tutorial introduction to get the reader up to speed with the basics of Python; experienced programmers from other object oriented languages such as Java may find that this is all the introduction to Python that they need. This is followed by a discussion of the Python object model then it moves on to discussing object oriented programming in Python. With a firm understanding of the Python object model, it goes ahead to discuss functions and functional programming. This is followed by a discussion of meta-progr
