I’ve stated before that one of the unique features of Emacs Lisp is that its closures are readable . Closures can be serialized by the printer and read back in with the reader. I am unaware of any other programming language that has this feature. In fact it’s essential for Elisp byte-code compilation because…
So we’re supposed to be writing a game, right? But in order to make progress, we have to fix a bug. And in order to fix the bug, we have to write a test. And in order to write a test, we have to write a test framework. And in order to write a test framework, we have to understand a thing or two about macros. Okay. So…
Algebraic effects and handlers provide a modular abstraction for expressing effectful computation, allowing the programmer to separate the expression of an effectful computation from its implementation. In this post, I will present an extension to OCaml for programming with linear algebraic effects, and demonstrate…
TypeScript is a big Superset of JavaScript which has many features which might not be shown in every beginner tutorial. This post has three of them to make your life easier learning TypeScript.
MT-NLG has 3x the number of parameters compared to the existing largest model of this type and demonstrates unmatched accuracy in a broad set of natural language tasks.
Thousands of cam girls live right now from Colombia, the US, Europe and Asia. Watch free with no signup, and see when each model is usually online.
This is a follow-up to Error handling in Rust from a couple of days ago. The moment we want to use error propagation for different error types, we have to rely on trait objects with Box<dyn Error>, which means we defer a lot of information from compile-time to runtime, for the sake of convenient error handling.
Making the Python interpreter faster
In the second part of our metaprogramming series, find out about the inner workings of macros in Elixir.
Monads and macros have an almost gnostic mystique about them. Why is that? Why does hardly anyone use both?
This may surprise you if you know me, but I’ve been learning Common Lisp for a few weeks now.
A deep-dive technical overview of how you can write CPython extensions in assembly (with a bonus tutorial on assembly programming)
While working on an article for the Monad.Reader, I’ve had the opportunity to think about how people learn and gain intuition for abstraction, and the implications for pedagogy. The heart of …
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…
Enumerating and analyzing 40+ non-V8 JavaScript implementations
A critical but informative look at the new structural pattern matching feature in Python 3.10, with real-world code examples.
A look at how Java 17 stacks up against Kotlin and Scala for development teams in 2021, and an overview of popular JVM technologies.
On August 15th, the following answer showed up on the Retrocomputing Stack Exchange site :
Get a closer look at how the Shenandoah garbage collector adds concurrent thread-stack processing, and reliable sub-millisecond pauses, in OpenJDK 17.
The macro Ecto Query dynamic/2 allows you to build query fragments and interpolate them into one large query. We get easy-to-manage query building in an accessible way. It allows you to control the parameters from the user and transparently create filtering of data stored in the database.
I’ve been using Go for a few years now, mostly in my open source project Lazygit. In my day job I use Ruby and Typescript, and I’ve also spent some time with Rust. Each of those languages have design quirks that can grind a developer’s gears, and although my own precious gears have been ground by every language I’ve…
I’ve seen people be genuinely puzzled about why functional programming is not more popular. For example I’m currently reading “Out of the Tar Pit” where after arguing for fu…
Yes, I am aware that I am interrupting our self-hosting PL/0 compiler series but I think it will be worth it. Earlier today, I got the J language system running on OpenBSD . I find it important to write these up, because it helps me preserve my own knowledge of what I did and hopefully it will help others porting…
When the subject of Java modules comes up in online discussions every so often, I get the sense that many people misunderstand what it is that modules are supposed to do. That's understandable, as the name 'modules' does not evoke the precise purpose of the feature. There are many kinds of modules, even in the Java…
