This post will show you how to use D to write a bare-metal “Hello world” program that targets the RISC-V QEMU simulator. In a future blog post ( now available ) we’ll build on this to target actual hardware: the VisionFive 2 SBC. See blog-code for the final code from this post. For a more complex example, see…
People in the programming language design community strive to make their languages more expressive, with a strong type system, mainly to increase ergonomics by avoiding code duplication in final software; however, the more expressive their languages become, the more abruptly duplication penetrates the language itself.
A very good friend of mine has been experimenting with trying to coax Chat-GPT4 to successfully do basic coding tasks. So have a lot of people these days, of course. In an idle moment, though, my friend submitted the following query:
For a while now I've been trying to find a good way to explain what structured concurrency is, and how it applies to Rust. I've come up with zingers such as: "Structured concurrency is structured programming as applied to concurrent control-flow primitives" . But that requires me to start explaining what structured…
I hope that the true promise of functional programming for parallel computing can be widely realized.
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…
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…
( This is part of a series on the design of zest . See the list of posts here .)
In the following series of blog posts I will document my attempts to write Linux modules using the Ada language. In part 1, I will demonstrate how to write in Ada and build a simple "hello world" Linux kernel module. Additionally, I will introduce a basic customized Ada runtime to support our "hello world" module…
Improving API function calls using inline assembly
It is thankfully common wisdom nowadays that documentation must be placed as near as possible to the code it documents, and should be fine-grained to a minimal unit of describability (the thing being documented). The practice provides numerous benefits to the codebase and project as a whole:
Sometimes it's even useful too
Everything was fine until BASIC entered the picture. Edsger Dijkstra in a hallucination of 2023’s AI Simplicity is the ultimate sophistication. Leonardo Da Vinci It is practically impossible to teach good programming to students that have had a prior exposure to BASIC: as potential programmers they are mentally…
This series of articles is a tutorial on the theory and practice of developing language parsers and compilers. Before we are finished, we will have covered every aspect of compiler construction, designed a new programming language, and built a working compiler.
Once upon a time, there were many music composition software packages, mostly written in Common LISP. To name a few I know, Common Music, Symbolic Composer (not related to the Symbolics Lisp Machine). Common Music is still available in source code but I doubt if anyone is still able to setup that. Symbolic Composer…
Full Slice Expressions in Golang — A Rare Slice Trick
Summary In this post I’ll go into detail about how, during my contracting work for Shimmer Industries (a company founded by Eskil Steenberg which is focused on developing a real-time lighting designing software), I worked on a piece of software which enabled us to use the MacOS and iOS APIs using a custom C API…
When programming in Go, the amount of error handling is something that slaps you in the face. Most API’s you deal with will expose errors. It can become overwhelming, but with a few tips and a guiding principle we can make handling errors easy, keep our code clean and give you the confidence that nothing is breaking…
Does Python still have a need for class without @dataclass?
co_lc is a lambda calculus extended with stackful coroutines. An efficient implementation for the compilation and virtual machine execution of co_lc is presented. The implementation supports tail-call optimization and eliminates all indirect calls by defunctionalizing closures.
This is a short introduction to Rust, intended for developers that already know another language. In the examples, Rust is compared with TypeScript, JavaScript or Java, sometimes with C++ or Kotlin.
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…
It's risky business fighting Intel, AMD, and Arm, and that's exactly what Star Five is trying to do with this: The chip on this new single board computer could be the start of a computing revolution—at least that's what some people think! The VisionFive 2 has a JH7110 SoC on it, sporting a new Instruction Set…
I've had some pretty surreal experiences while making Vale. 0 The weirdest was when I realized the hidden fundamental truth beneath a lot of the programming languages we use today.
Following up from the last post, there is a lot more we need to cover. This was intended to be the post where we talk exclusively about benchmarks and numbers. But, I have unfortunately been perfectly taunted and status-locked,
With the release of rust 1.70, there was some surprise and frustration that unstable test features now require nightly , like all other unstable features in Rust. One of the features most affected is --format json which has been in limbo for 5 years . This drew attention to a feeling I've had: the testing story in…
