Clojure core.async.flow (github.com/clojure)
The fundamental objective of core.async.flow is to enable a strict separation of your application logic from its topology, execution, communication, lifecycle, monitoring and error handling, all of which are provided by and centralized in, c.a.flow, yielding more consistent, robust, testable, observable and operable systems.

In-Depth Ruby Concurrency: Navigating the Ruby Concurrency Landscape (jpcamara.com)
I was honored to present a talk on Ruby concurrency at RubyConf 2024. It represents a high-level distillation of much of my writing and research over the past year. The conference itself was great, and presenting was such a fun experience.

Linux 6.13 Quadrupling Workqueue Concurrency Limit (phoronix.com)
The Linux kernel Workqueue (WQ) is used for handling asynchronous process execution. For the past many years there has been an upper limit on the number of workqueue execution contexts per CPU at 512, but with Linux 6.13 that is being quadrupled to a limit of 2048.

Playground Wisdom: Threads Beat Async/Await (pocoo.org)
It's been a few years since I wrote about my challenges with async/await-based systems and how they just seem to not support back pressure well. A few years later, I do not think that this problem has subsided much, but my thinking and understanding have perhaps evolved a bit. I'm now convinced that async/await is, in fact, a bad abstraction for most languages, and we should be aiming for something better instead and that I believe to be thread.

Understanding Concurrency, Parallelism and JavaScript (rugu.dev)
Up until now, I was not aware that concurrency and parallelism were actually different things since they are often used interchangeably by some. I just learned that this is not the case while reading Chapter 9 of the book “Clojure for the Brave and True.”
