To implement its safety guarantees, the Rust compiler keeps careful track of ownership and references throughout a program. This makes writing certain kinds of data structures challenging; in particular, data structures that have circular references.
Contrasting how each language handles iteration helps understand how to work effectively in either.
Sometimes we start things but decide midway through that we would prefer to rather not be doing them. That process is sometimes referred to as cancellation. Say we accidentally clicked "download" on a large file in the browser. We should have a way to tell the computer to stop downloading it.
Rubinius began as a metacircular implementation of Ruby and was billed as Ruby in Ruby . Today the core and much of the standard library, parser, bytecode compiler, and other components are implemented in Ruby, but the interpreter, runtime, GC and other components, are written in C++.
Go 1.18 will be a significant release of the programming language that will contain some major features that I’m excited about. The upcoming version is scheduled for early 2022. The first beta should be out in a month. Let’s take a look at some of the new features that will be available.
Common Lisp is one of the few languages which is both dynamic and also gives you a full native compiler and the ability to declare types ...

This blog post discusses a few alternative Rust-language memory models. I hope that this discussion is of value to the Rust community, but in the end, it is their language, so it is also their choice of memory model. This discussion takes the Rust fearless-concurrency viewpoint, tempered by…
C++20 added minimal support for coroutines. I think they’re done in a way that really doesn’t fit into C++, mostly because they don’t follow the zero-overhead principle. Calling a…
Async Ruby is a powerful and highly scalable concurrency feature. It's available today, it's production-ready, and it's an awesome addition to Ruby language!

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…
During the annual Python core development sprint we held a meeting with Sam Gross, the author of nogil, a fork of Python 3.9 that removes the GIL. This is a non-linear summary of the meeting.

The best way to learn a new programming language, just like a human language, is from example. To learn how to write code you first need to read someone else’s code. But who is the best person to learn from? Which code should we read? Where should we look to find it?
Recently, the awesome-lisp-companies list was posted on HN, more people got to know it (look, this list is fan-cooked and we add companies when we learn about one, often by chance, don’t assume it’s anything “official” or exhaustive), and Alex Nygren informed us that his company Kina Knowledge…
Since Python 3.5 was released in 2015 including PEP 484 and the typing module type hints have grown from a nice-to-have to an expectation for popular packages. To fulfill this expectation our team...
I’ve used F# a lot in the last 3 years and for quite some time I wanted to collect a few good starting points to venture into F# in one place. I also wanted ...
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.

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.
