Alan Kay and OO Programming
Dr. Alan Kay invented the term "OO Programming", but he states that modern OO programming isn't what he meant. What did he mean?

Jumping Back and Forth
The order that our mind imagines is like a net, or like a ladder, built to attain something. But afterward you must throw the ladder away, because you discover that, even if it was useful, it was meaningless.

Shell Completions in Rust
If you've ever hit the tab key while typing commands in the shell, you are familiar with the value of shell completions. Bash has some default completion behavior, which is why you can type hel<TAB> and end up with help . It is also possible to add additional completion scripts which define the completion behavior for…

F() vs. F(void) in C vs. C++
Prefer f(void) in C to potentially save a 2B instruction per function call when targeting x86_64 as a micro-optimization. -Wstrict-prototypes can help. Doesn’t matter for C++.

Prolog's Death (2010)
Maarten van Emden just posted a terrific and authoritative account of one episode in the history of Prolog under the title “Who Killed Prolog” (and, tantalizingly, promises another epis…

Go makes it easier to write correct, clear and efficient code
The main reasons Go makes it easier (than Java or Python) to write correct, clear and efficient code are discussed in this comprehensive report by an expert Go and Java developer.

A final proposal for Rust await syntax
This is an announcement regarding the resolution of the syntax for the await operator in Rust. This is one of the last major unresolved questions blocking the stabilization of the async/await feature, a feature which will enable many more people to write non-blocking network services in Rust. This post contains…

What to Know Before Debating Type Systems (2008)
I was asked by someone to put this old piece of writing of mine somewhere more permanent, so here it is. A few comments off the top: This isn’t new. I wrote it years ago. Yes, I’m a b…

A Guide to Rust Graphics Libraries as of 2019
You are seeing this because the administrator of this website has set up Anubis to protect the server against the scourge of AI companies aggressively scraping websites . This can and does cause downtime for the websites, which makes their resources inaccessible for everyone.

Modern C++ for C Programmers
2018 is an exciting time to be a programmer, with so many good “full service” programming languages to choose from: C, C++ 2017, Go, Python, Rust and who knows Swift too. Programming languages are complicated beasts - even the simplest languages have specifications that run (or would run) in the hundreds of pages, and…

How Many Type Parameters Can a Java Method Have?
and this made me wonder how many type parameters a method could have. As far as I can tell, the Java Language specification says nothing about this question. 1

A PHP Compiler, a.k.a. the FFI Rabbit Hole
It’s no secret that I’m into building toy compilers and programming languages. Today I’m introducing something that’s not a toy (I hope). Today, I’m introducing php-compiler (among many other projects

Defeating Racket’s separate compilation guarantee
Being a self-described programming-language programming language is an ambitious goal. To preserve predictability while permitting linguistic extension, Racket comes equipped with a module system carefully designed to accommodate composable and compilable macros . One of the module system’s foundational properties is…

Comparing JVM alternatives to JavaScript
I am mostly a backend developer, but every now and then I need to do some frontend work. Even if just for personal use.

Asynchronous Programming in Rust
Asynchronous programming in Rust continues to make exciting strides, including the upcoming stabilization of the futures API . But, while these core APIs make it possible to write async Rust code today, it's not easy: it's a far cry from the smoothness of synchronous code.

Learning Parser Combinators with Rust
This article teaches the fundamentals of parser combinators to people who are already Rust programmers. It assumes no other knowledge, and will explain everything that isn't directly related to Rust, as well as a few of the more unexpected aspects of using Rust for this purpose. It will not teach you Rust if you don't…

The Power of Lifetimes
The execution of a program unfolds over some interval of time. The lifetime of every temporary resource (e.g., variable or object) is the time span between that resource’s “creation” and “destruction”. This lifetime is wholly contained within the typically-longer lifetime of the program.

Languages I want to write
I spent this weekend writing a Forth designed for music synthesis, and it reminded me what a joy writing programming languages is! I have a big list of programming language experiments that I want to try, but it's mostly been in my head so far. Here's a living document of some of the languages I want to write.

Lvalues, rvalues, glvalues, prvalues, xvalues, help (2018)
