Crafting Interpreters
We’ll spend the rest of this book illuminating every dark and sundry corner of the Lox language, but it seems cruel to have you immediately start grinding out code for the interpreter without at least a glimpse of what we’re going to end up with.

I want off Mr. Golang’s Wild Ride (2020)
My honeymoon with the Go language is extremely over. This article is going to have a different tone from what I’ve been posting the past year - it’s a proper rant. And I always feel bad writing tho...

Compile time evaluation in Nim, Zig, Rust and C++
Evaluating code at compile time is a capability that most, if not all, compiled programming languages possess, even if it can't be directly used by the programmer, but rather applied as an optimization. In this post, we'll explore a bit how to execute code at compile time in Nim, Zig, Rust and C++.

Tcl the Misunderstood (2006)
In an article recently linked from reddit entitled Tour de Babel you can read (among lots of other nonsense): Heck, people still use Tcl as an embedded interpreter, even though Python is far superior to Tcl in every conceivable way -- except, that is, for the frost thing.

Rust9x: Compile Rust code for Windows 95, NT and above
You might remember my old post about the journey to get at least a bit of Rust code working for Windows 98 SE . Well, I'm back, this time with a more ambitious package:

Generate Python extensions using Nim language
A Python Extension is generally some code written in language other than python to extend the python ecosystem by exposing an interface compatible with Python API.Such extensions are generally in form of compiled code and loaded dynamically by the Python runtime ...

Pointers Are Complicated III, or: Pointer-integer casts exposed
In my previous blog post on pointer provenance, I have shown that not thinking carefully about pointers can lead to a compiler that is internally inconsistent: programs that are intended to...

Making Rust a Better Fit for Cheri and Other Platforms
Recently, Aria Beingessner published an interesting essay “ Rust’s Unsafe Pointer Types Need An Overhaul ”. There are several parts to this essay, all of which address issues which cause me pain in Rust, and which I would love to see fixed. I want to focus on one issue: Rust’s usize conflates address, data, and object…

What Is Rust's Unsafe? (2019)
I’ve seen a lot of misconceptions around what the unsafe keyword means for the utility and validity of Rust and its marketing as a “safe systems language”. The truth is a lot more complicated than a single pithy tweet can possibly sum up, unfortunately; here it is as I see it.

Rethinking Visual Programming with Go
This is a blog version of the talk I gave at GopherCon Europe 2019 (Canary Islands Edition) , where I shared my thoughts on why Visual Programming Languages have failed and revealed for the first time my experiment on visualizing Go code.

Faster Sorting with Go Generics
Recently, a new set of sorting functions has landed in Go's golang.org/x/exp/slices package [1] . These functions leverage Go generics to provide a more ergonomic API for sorting (without requiring users to implement sort.Interface ), and also deliver a nice performance improvement, as the CL demonstrates.
