Gleam is a Type-Safe programming language that transpiles to Erlang And javascript . , so you can run its code on the BEAM. I’ve slept on Gleam for a while because its syntax. It was too much Rust and not enough Elixir for me.
Learn Ruby metaprogramming: call methods dynamically with send, define them at runtime with define_method, and handle missing calls with method_missing.
Sigils have a bit of a bad reputation. According to their detractors, sigils are “just a way of encoding type information” in variable names – basically a glorified version of apps Hungarian notati…
TableGen is a language used within the LLVM project for generating a variety of files, when manual maintenance would be very difficult. For example, it is used to define all of the instructions that can be used on a particular architecture.
New SBCL versions are usually released at the end of each month: check the Sourceforge File List to see the current version. The new features of the two most recent SBCL releases are listed below.
Coding in Rust and others; making coding videos.
You probably know how to use async/await. But have you ever wondered how it works under the hood?
Pattern matching and exhaustive switches come together to enable functional style data models that blend seamlessly with Dart’s…
This release is the Reference Implementation of version 21 of the Java SE Platform, as specified by JSR 396 in the Java Community Process.
I’ve been on a C kick recently as I learn the intricacies involved in low level programming. As a Data Scientist/Python Programmer I work with strings all the time. People say that handling strings in C range anywhere from tricky to downright awful. I was curious so I decided to see how deep the rabbit hole went.
Now that Java 21 is features complete (Rampdown Phase Two at the day of writing), it’s time to walk through all the functionalities that bring to us, developers, this new version. This article is part of a series on what’s new on the last versions of Java, for those who wants to read the others,
Listen, I didn’t plan on making a whole ‘writing X like Y’ series. But here we are.
Update (2023-07-21): I was being a bit overly brief with liberal use of ... to mean “unimportant” in the code examples. Ginger Bill (creator of Odin) noted it might be clearer to have more correct/explicit Odin and Zig code for the examples given people would be less familiar. Those has been updated For the past few…
Welcome to Learning Zig, an introduction to the Zig programming language. This guide aims to make you comfortable with Zig. It assumes prior programming experience, though not in any particular language.
On April 8, 2020, John Horton Conway developed symptoms of COVID-19. On April 11, 2020, he succumbed to the disease. 1 2 3 4
Designing APIs is hard. Designing good APIs that future people will not instantly classify as "total crap" is even harder. There are typical...
In my last post about Zig and Rust, I mentioned that Rust is a scalable language. Let me expand on this a bit.
It's been just over three months since we announced the Guile on WebAssembly project (codenamed Hoot ). Since then we've brought on two fantastic hackers to develop the project and progress has been quick.
I sometimes get asked why I use Perl so much. Am I not a fan of strongly typed functional programming? Yeah, I am. Ask me to write something that is known, for sure , to become a big system and I’ll pick strongly typed functional programming without hesitation. 1 1 And, of course, put me in a team that uses Blub, and…
Every March, developers worldwide each try to make a roguelike game in less than 168 hours as part of the 7DRL Challenge . Roguelike games are hard , involving procedural level generation, pathfinding, line-of-sight algorithms, and more dijkstra maps than you can imagine.
The Lua programming language is unusual among its peers. It’s a dynamically typed, scripting language with a really small core (100-200kB), but runs efficiently, has far simpler semantics than other similar languages, and is just as old as the giants like JavaScript, Python, and Ruby – first made in a research lab…
My paper P1144R8 “std::is_trivially_relocatable” has, in the past few months, been joined by three(!) papers out of Bloomberg:
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…
Why the function signatures in the slices packages are so complicated.
Go 1.21 is the first perfectly reproducible Go toolchain.
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:
