How Old School C Programmers Process Arguments
Here’s a bit of code from Kernighan’s and Ritchie’s seminal text, The C Programming Language . I’m not sure I’d actually recommend coding this way (as written in the book, the entire program has only one comment), but it’s so darn clever and concise, I can’t help but post it. This snippet is part of a larger program…

Borrow checking without lifetimes
This blog post explores an alternative formulation of Rust’s type system that eschews lifetimes in favor of places . The TL;DR is that instead of having 'a represent a lifetime in the code, it can represent a set of loans , like shared(a.b.c) or mut(x) . If this sounds familiar, it should, it’s the basis for polonius…

Destructuring and Recursion in ES6
Arrays are JavaScript’s “native” representation of lists. Lists are important because they represent ordered collections of things, and ordered collections are a fundamental abstraction for making sense of reality.

Turbo Pascal on CP/M, MSX-DOS and MS-DOS
The Pascal language was named after Blaise Pascal (see picture), a French mathematician who was a pioneer in computer development history. In 1641, at the age of eighteen, Pascal constructed the first arithmetical machine, arguably the first computer. He would improve upon the instrument eight years later. In 1650…

How Javascript Prototypal Inheritance Really works
Everywhere on the web we read that Javascript has prototypal inheritance. However Javascript only provides by default a specific case of prototypal inheritance with the new operator. Therefore, most of the explanations are really confusing to read. This article aims to clarify what is prototypal inheritance and how to…

Multithreading in modern C++
With the new C++11 Standard, C++ faces the first time challenges of multicore architectures. The 2011 published standard defines how a C++ program has to behave in the presence of multiple threads. The C++11 multithreading capabilities are composed of two components. This is, on the one hand, the defined memory model…

When the Compiler Bites
So far this year I’ve been bitten three times by compiler edge cases in GCC and Clang, each time catching me totally by surprise. Two were caused by historical artifacts, where an ambiguous specification lead to diverging implementations. The third was a compiler optimization being far more clever than I expected…

Python becomes a platform. Thoughts on the release of clojure-py.
The recent announcement of clojure-py made some noise in the Clojure community, but not, as far as I can tell, in the Python community. For those who haven’t heard of it before, clojure-py is…

Smalltalk-87
In late 1986 and early 1987 an ad hoc group of Smalltalk implementors got together to see if they could agree on a design for the next major version of Smalltalk, after Smalltalk-80. The intent was that what they agreed upon would feed into an IEEE standardization process. That process never got
