They Called It LISP for a Reason: List Processing (2005)
Lists play an important role in Lisp--for reasons both historical and practical. Historically, lists were Lisp's original composite data type, though it has been decades since they were its only such data type. These days, a Common Lisp programmer is as likely to use a vector, a hash table, or a user-defined class or…

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…

Swift 5 Exclusivity Enforcement
The Swift 5 release enables runtime checking of “Exclusive Access to Memory” by default in Release builds, further enhancing Swift’s capabilities as a safe language. In Swift 4, these runtime checks were only enabled in Debug builds. In this post, I’ll first explain what this change means for Swift developers before…

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…

JIT and Ruby's MJIT
If you already know lots about JIT in general and Ruby’s MJIT in particular… you may not learn much new in this post. But in case you wonder “what is JIT?” or “what is MJIT?” or “what’s different about Ruby’s JIT?” or perhaps “why in the world did they decide to do THAT?”… Well then, perhaps I can

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…
