A Comparison of Differential Equation Solver Suites
Many times a scientist is choosing a programming language or a software for a specific purpose. For the field of scientific computing, the methods for solving differential equations are one of the important areas. What I would like to do is take the time to compare and contrast between the most popular offerings. This…

Implementing Algebraic Effects in C
We describe a full implementation of algebraic effects and handlers as a library in standard and portable C99, where effect operations can be used just like regular C functions. We use a formal operational semantics to guide the C implementation at every step where an evaluation context corresponds directly to a…

The language of choice
Propositional logic was discovered by Stoics around 300 B.C., only to be abandoned in later antiquity and rebuilt in the 19th century by George Boole’s successors. One of them, Charles Peirce, saw its significance for what we now call logic circuits, yet that discovery too was forgotten until the 1930s. In the ’50s…

The Design and Use of QuickCheck
QuickCheck is the grandfather of property-based testing libraries. Despite being imitated in over thirty languages, the original implementation remains pre-eminent due to the type system and consistent logic of the Haskell language in which it is written.

Origins and History of Unix, 1969-1995 (2003)
A notorious ‘second-system effect‘ often afflicts the successors of small experimental prototypes. The urge to add everything that was left out the first time around all too frequently leads to huge and overcomplicated design. Less well known, because less common, is the ‘third-system effect’; sometimes, after the…

Not Explicit
Oftentimes when I am conversing about the design of Rust with other users - as on RFCs or the internals forum - I witness a peculiar remark about “explicitness.” It usually goes something like this: I do not like Feature Design X because it is too implicit. Magic is okay in Other Language Y, but Rust is supposed to be…
