Memories: Edinburgh ML to Standard ML
Dave MacQueen (with Robert Harper and John Reppy) has written a 100-page History of Standard ML . Here I offer my brief, personal and utterly subjective impressions of its early days, up to the deeply unfortunate schism that created what was then called Caml . Standard ML was a tragic missed opportunity. But even…

Programming as interaction: A new perspective for programming language research
In programming research, we say a lot about programs and languages, but very little about the actual process of programming. One simple trick that will make programming language research significantly more interesting is to think about programs not as expressions, but as a result of a sequence of interactions that…

Counting Clojure Code
For better or worse, we count lines of code. We (hopefully) feel a little dirty when we do it, because it's a flawed metric. But we do it . We do it on large codebases and small code snippets . Even badass hacker David Nolen does it .

Erlang: A Generalized TCP Server
In my last few articles about Erlang we've covered the basics of network programming with gen_tcp and Erlang/OTP's gen_server, or generic server, module. Let's combine the two.

The Python Paradox is now the Scala Paradox
Paul Graham has written a bunch of good essays on entrepreneurship, laying down much of the philosophy behind Y Combinator . If you’ve not read any of them yet, you should go and read them now – they contain lots of wisdom.

A case against currying
Curried functions are probably one of the first new things you come across if you go from an imperative language to a functional language. In purely functional languages, the convention is to define an n-parameter function inductively by staggering the parameters: applying the function to argument #1 returns a…

Deconstructing "K&R C"
Learn C The Hard Way (LCTHW) is a practical book teaching real world useful C using the same proven Learn The Hard Way method. LCTHW teaches real robust C coding and defensive programming tactics on real hardware rather than abstract machines and pedantic theory. The book emphasizes breaking your code on purpose, and…

The C++ Killers (Not You, Rust)
All the “C++ killers”, even these which I wholeheartedly love and respect like Rust, Julia, and D, help you write more features with fewer bugs, but they don't much help when you need to squeeze the very last FLOPS from the hardware you rent. As such, they don’t have a competitive advantage over C++. Or, for that…

Strategic Scala Style: Principle of Least Power
The Scala language is large and complex, and it provides a variety of tools that a developer can use to do the same thing in a variety of ways. Given the range of possible solutions to every problem, how can a developer choose which one should be used? This is the first in a series of blog posts aiming to provide…
