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.
In part 1 I dove into Spotify Codes and explained the general technical concepts of how they work. If you haven’t read that post you should check it out. I shared it on reddit where it generated a lot of interesting discussion. Ludvig Strigeus, a key early developer at Spotify and the person who invented Spotify…
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.
I worked on Rust part-time for several years at Mozilla. During that period I regularly summarized how the compiler’s performance had improved. For example: 2017-11-12 to 2019-07-24.
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++.

🔎I authored this blog post whilst I was an employee of Gitpod for Gitpod. I no longer work at Gitpod. In what seems like a long time ago, in part because it is, I learned the catastrophic capabilities of this command the hard way, and I'm sure folks my

I am very proud to say that after about 10 months of work I finished writing my Emacs Lisp book . If you haven’t heard of it yet, it’s called “Hacking your way around in Emacs” and it is an intermediate-level textbook on Emacs Lisp, showing a lot of useful things on about 100 pages.
So I couldn't sleep the other night, and my brain wanted to think about odd problems… Ever had a script that's compatible with both, Python 2 and 3, but you didn't want to bother the user to know whic
In the aftermath of my previous blog post about using Nextjournal's clojure-mode for better highlighting, I tried optimizing the JS output and got a look at the internals of CodeMirror 6 . I realized that writing a Clojure highlighter from scratch wasn't that hard if you had the right tools at hand:
