SectorC: A C Compiler in 512 bytes
SectorC ( github ) is a C compiler written in x86-16 assembly that fits within the 512 byte boot sector of an x86 machine. It supports a subset of C that is large enough to write real and interesting programs. It is quite likely the smallest C compiler ever written.

Why Lisp?
A lot of people ask us the question, why do we choose to use Common Lisp as our primary development language? Often times the question comes disguised as a suggestion: "Flask is a great webserver you should consider using". This is a well intentioned suggestion- of course we would like to use the best tools available!…

The seven programming ur-languages (2021)
I regularly hear people asking which programming language to learn, and then reeling off a list of very similar languages (“Should I learn Java, C#, C++, Python, or Ruby?”). In response I usually tell them that it doesn’t really matter, as long as they get started. There are fundamentals behind them.

Driving Compilers
I remember how pleasant it was to learn to program in C. There were so many good books explaining not only the language but also the standard library. I devoured both The C Programming Language (K&R) by Kernighan/Ritchie and The Standard C Library by P.J. Plauger. Then came Expert C Programming by Van der Linden and…

Why split lexing and parsing into two separate phases?
“lex and yacc” are two terms that are used together so often that they can seem indivisible. lex takes a string as input and divides it up into lexemes (roughly speaking “words”) and yacc takes a sequence of lexemes and parses them. Since some parsing approaches such as recursive descent parsing unify these phases…
