Using unwrap() in Rust is okay
One day before Rust 1.0 was released, I published a blog post covering the fundamentals of error handling . A particularly important but small section buried in the middle of the article is named “ unwrapping isn’t evil ”. That section briefly described that, broadly speaking, using unwrap() is okay if it’s in…

MiniRust
I have been thinking about the semantics of Rust – as in, the intended behavior of Rust programs when executed, in particular those containing unsafe code – a lot. Probably too much. But al...

The pervasive effects of C's malloc() and free() on C APIs
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…

C99 doesn't need function bodies, or 'VLAs are Turing complete'
The 1999 revision to the C programming language brought several interesting changes and additions to the standard. Among those are variable length arrays, or VLAs for short, which allow array types to have lengths that are determined at runtime. These can show up in different contexts, but for the purposes of this…

Formally Verifying Rust's Opaque Types
Introduction The other day I was reading this blog post covering existential types in Rust (also known as impl Trait or opaque types). In that blog post, the author makes the following claim. We’re going to have to take a slight diversion into type theory here because it motivates a result that is perhaps intuitive…

Carbon’s most exciting feature is its calling convention
Last week, Chandler Carruth announced Carbon, a potential C++ replacement they’ve been working on for the past two years. It has the usual cool features you expect from a modern language: useful generics, compile-time interfaces/traits/concepts, modules, etc. – but the thing I’m most excited about is a tiny detail…

Some Thoughts on Zig
One of the biggest things Zig has going for it—especially compared to Rust—is that it is (relatively) small. That sits in tension with Rust’s approach to solving memory safety problems, and sets up a nice challenge for future programming language designers.

Learning Go as a Python Developer: The Good and the Bad
I've been thinking about supplementing another language to Python for some time – mainly to cope with areas Python struggles with, or is a pain to use (which I'll go over in a minute). I had used C/C++ some years ago, but don't want to go back to them. C

Beating the Averages (2001)
April 2001, rev. April 2003 (This article is derived from a talk given at the 2001 Franz Developer Symposium.) In the summer of 1995, my friend Robert Morris and I started a startup called Viaweb . Our plan was to write software that would let end users build online stores. What was novel about this software, at the…
