John Carmack on Inlined Code
The real enemy addressed by inlining is unexpected dependency and mutation of state, which functional programming solves more directly and completely. However, if you are going to make a lot of state changes, having them all happen inline does have advantages; you should be made constantly aware of the full horror of…

Clojure Distilled
The difficulty in learning Clojure does not stem from its syntax, which happens to be extremely simple, but from having to learn new methods for solving problems. As such, we'll focus on understanding the core concepts and how they can be combined to solve problems the functional way.

Careful with that Buffer
Last week I was sorting through several sets of Microsoft C 5.1 disks from 1988 (more about that later). While I was comparing the disk images to see whether the disks were the same or not, despite different labels and part numbers, I did a double take when I realized that a file with random e-mail fragments was, in…

Programming without objects
Recently I gave an itemis internal talk about basic functional programming (FP) concepts. Towards the end I made a claim that objects and their blueprints (a.k.a. classes) have severe downsides and that it is much better to "leave data alone", which is exactly how Clojure and Haskell treat this subject.
