I've started working on a new edition of Ruby Under a Microscope that covers Ruby 3.x. I'm working on this in my spare time, so it will take a while. Leave a comment or drop me a line and I'll email you when it's finished.
One of the first things any Rust programmer learns is that you can’t pass an object and a reference to that object around at the same time. It’s impossible to do, even indirectly. This limitation has been the subject of countless questions on Stack Overflow and posts on Reddit and the Rust forums and anywhere else…
Of course you want to design (and implement!) your own programming language! It’s fun. It’s creative. It’s empowering.
A modest mathematical framing of language
wingolog: article: the last couple years in v8's garbage collector
Optimizing compilers like to keep track of each IR instruction’s effects. An instruction’s effects vary wildly from having no effects at all, to writing a specific variable, to completely unknown (writing all state).
(From someone who has spent far too much time thinking about the designs of programming languages)
This is my Code BEAM Europe 2025 talk, converted to a blogpost.
I can’t think of any other language in my 45 years long career that surprised more than Zig . I can easily say that Zig is not only a new programming language, but it’s a totally new way to write programs, in my opinion. To say it’s merely a language to replace C or C++, it’s a huge understatement.
If you’re already familiar with SIMD, the table is all you need. And if you’re not, you will understand the table by the end of the…
Smalltalk was the second major influence on Ruby's design. A different kind of influence, since almost nothing of Smalltalk's syntax made into Ruby. But many of the details of how objects work are directly inspired by Smalltalk, including the idea that every piece of data is part of the object system.
An "impossible" Ruby bug: Hashes becoming Strings at runtime. 2,700 identical crashes. No corruption. Just objects changing what they are. Deep dive.
I graduated last month, and my GSoC project along with my startup work finally wrapped up. To take a proper break and enjoy some deliberate...
Some time ago, I played around with decompiling Java class files in a more efficient manner than traditional solutions like Vineflower allow. Eventually, I wrote an article on my approach to decompiling control flow, which was a great performance boost for my prototype. At the time, I believed that this method can be…

Friendly Attributes pattern enables writing human-friendly attributes with compact and flexible syntax.
To be fair, nobody asks me this exact question. But people have regularly asked why Isabelle dispenses with proof objects. The two questions are essentially the same, because proof objects are intrinsic to all the usual type theories. They are also completely unnecessary and a huge waste of space. As described in an…
The Arduino Uno Q is... a weird board. It's the first product born out of Qualcomm's buyout of Arduino. It's like if you married an Intel CPU, and a Raspberry Pi RP2040 microcontroller—oh wait, Radxa's X4 did that. Arduino even tried it before with their old Yún board, which had Linux running on a MIPS CPU, married to…

I’ve been watching the Zig language for a while now, given that it was created for writing audio software (low-level, no allocations, real time). I never paid too much attention though, it seemed a little weird to me and I didn’t see the real need. Then I saw a post from Andrew Kelley (creator of the language) on…
