Ruins of forgotten empires: APL languages
One of the problems with modern computer technology: programmers don’t learn from the great masters. There is such a thing as a Beethoven or Mozart of software design. Modern programmers seem…

Embracing Modern C++ Safely, Book Review
C++11 has been around for around 11 years and C++14 for 8. From my experience, I see that even today, many companies struggle to use those standards in production in the most efficient way. As always, with new stuff came benefits, risks, and increased learning effort. Fortunately, with a new book written by top C++…

Assembly Language: Still Relevant Today
First, no, I don't do every thing in assembly. I use other languages too. Assembly language does have its place though. Second, a few of my points may not apply to highly complex processors; for example, self-modifying code may not work on a processor with an instruction cache .

What is a programmable programming language? (2019)
When I was still researching this fabled obscure language called Lisp one thing people kept saying about it is that “Lisp is a programmable programming language”, but I could never figure out what they meant by that. It sounds like a smug buzzword or like a gimmick from an academic toy language. Lisp programmers have…

Your C is not standard C
this is an incomplete list of some incompatibilities between c as it's written in the standard and c as it exists in the real world for people who use gcc/clang + glibc/musl.

Rust via its Core Values
I have a couple of ideas about learning programming languages. The first is that we do it wrong. I’m sure you’ve experienced this. You try learning a new language and can’t quite see how it all works. Why do I use this syntax here and some other syntax over here? We get frustrated by all the weird bits and go back to…

Comparing Pythagorean triples in C++, D, and Rust
EDIT: As pointed out in the Rust reddit thread, the Rust version can be modified to run faster due to a suble difference between ..=z and ..(z+1). I’ve updated the measurements with rustc0 be…

Yes, I am still learning Rust
Recently, I got yet another nice email from a “talent sourcing specialist” asking me if I’d like to work for their company. This one stood out from the usual blockchain recruiting spam by actually looking at this blog. And they told me their expectations were lowered by the front matter stating that I’m currently…

My mental model of Clojure transducers
I’ve been programming in Clojure for a long time, but I haven’t been using transducers much. I learned to mechanically transform (into [] (map f coll)) to (into [] (map f) coll) for a slight performance gain, but not much beyond that. Recently, however, I’ve found myself refactoring transducers-based code at work…

Clojure's machine learning ecosystem
I had a really enlightening talk with Daniel Slutsky this week (who is an exceptional data scientist, software engineer, and community organizer I highly…

Turbo 8 is dropping TypeScript
By all accounts, TypeScript has been a big success for Microsoft. I've seen loads of people sparkle with joy from dousing JavaScript with explicit types that can be checked by a compiler. But I've never been a fan. Not after giving it five minutes, not after giving it five years. So it's with great pleasure that I can…

Python vs Common Lisp, workflow and ecosystem (2019)
I learned Java and C at school, I learned Python by myself and it was a relief. After 8 years working and doing side projects in Python and JavaScript (mostly web dev, Django/Flask/AngularJS/Vuejs), I am not satisfied anymore by the overall experience so I’m making Common Lisp my language of choice.I am not here…

Scala: Understanding implicits
In previous posts, we covered the most popular implicit use cases. What is left to complete the picture is the mechanics of implicits itself.

Non-Lexical Lifetimes in Rust
Over the last few weeks, I’ve been devoting my free time to fleshing out the theory behind non-lexical lifetimes (NLL). I think I’ve arrived at a pretty good point and I plan to write various posts talking about it. Before getting into the details, though, I wanted to start out with a post that lays out roughly how…

First look at Clojure.core.typed
I just heard that core.typed is ready for production. Which is great timing because I'm working with a new team and they like types.

Retrofitting JIT Compilers into C Interpreters
C interpreters are a common language implementation technique and the basis for the reference implementations of languages such as Lua, Ruby, and Python. Unfortunately, C interpreters are slow, especially compared to language implementations powered by JIT compilers. In this post I’m going to show that it is possible…

A gentle intro to assembly with Rust
One of the things I’ve wanted to do for a while is really dig into assembly and get into the weeds of how programs actually run. A rework of the asm macro has recently landed in nightly rust so it seemed like a good time.

Fun with Lisp: Programming the NES (2012)
"Low-level programming is good for the programmer's soul." -John Carmack When the complexity of modern computing gets fatiguing, I look back to the simpler machines of my childhood. I grew up surrounded by various 8-bit and 16-bit machines (most of them already a few years outdated at the time),…

Let’s Run Lisp on a Microcontroller
I was inexplicably amazed by Lisp since the first day I've seen how Lisp programs look.
