Why I haven't jumped ship from Common Lisp to Racket just yet
Matthias Felleisen jested "Why are you still using CL when Scrbl/Racket is so much better :-)" ? My response was as follows: Dear Matthias, you are right Racket is so much better in so many dimensions. I use Lisp because I just can't bear programming in a language without proper syntactic…

Pointers Are More Abstract Than You Might Expect in C
A pointer references a location in memory and dereferencing a pointer refers to the lookup of the value of the memory location the pointer references. The value of a pointer is a memory address. The C standard does not define the representation of a memory address. This is crucial since not every architecture makes…

Why I still reach for Lisp and Scheme instead of Haskell
Scheme (and Lisp) lets you express complex systems and problem domains in simpler terms than any other language can. For all its brilliance, Haskell resists most of the attempts people make to just hack and write useful code quickly.

Why don't you use dependent types?
To be fair, nobody asks me this exact question. But people have regularly asked why Isabelle dispenses with proof objects. The two questions are essentially the same, because proof objects are intrinsic to all the usual type theories. They are also completely unnecessary and a huge waste of space. As described in an…

Comparing Rust and Java
It may not be obvious from my other blog entries, but I work as a Java developer. I also freely confess to enjoy it, which probably makes me part of some minority.

How LLVM Optimizes a Function
This is very nice summary of IR Passes. I found “InstCombine” pass to be easier to start with to understand the code flow in LLVM IR Pass. Maybe the beginners can start with that first.
