Efficient concurrent programming libraries are essential for taking advantage of fine-grained parallelism on multicore hardware. In this post, I will introduce reagents , a composable, lock-free concurrency library for expressing fine-grained parallel programs on Multicore OCaml . Reagents offer a high-level DSL for…
One feature of Rust that I'm rather enamoured with is its macro system. Known as "macro by example" (MBE) or sometimes referred to as macro_rules , it provides you with an impressive amount of power whilst not allowing for the sort of evil tricks you can pull in C/C++.
Covers general elements of computer hardware useful to know before reading the rest of the tutorials
By now it is difficult to imagine that once there was a time when the utility, and even the possibility, of recursion in programming was in doubt. Yet that was true of the programming community aro…
An overview of a paper that presents a reference implementation of a defer mechanism (co-authored with Robert C. Seacord) has been accepted for publication at SAC’21. The full version is avai…
👋🏼 This is part of series on concurrency, parallelism and asynchronous programming in Ruby. It’s a deep dive, so it’s divided into 12 main parts: Your Ruby programs are always multi-threaded: Part 1 Your Ruby programs are always multi-threaded: Part 2 Consistent, request-local state Ruby methods are colorless The…
I've been building enterprise Java web apps since servlets were created. In that time the Java ecosystem has changed a lot but sadly many enterprise Java…

As we've been building Mach engine, we've been using a neat little pattern in Zig that enables writing flag sets more nicely in Zig than in other languages. Here's a brief explainer.
Over the last 25 years, I’ve written a lot of event-driven code in C++. A typical example of event-driven code is registering a callback that gets invoked every time a socket has data to be read. Once you have read an entire message, possibly after many invocations, you parse the message and invoke another callback…
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…
Integer overflow detection/handling in Rust is sometimes misunderstood.
Following up on my recent Scala posts , some commented that because I haven't used Scala seriously, my opinion is of little value. I respo...
About a year ago, I published a Rust crate called inline-python, which allows you to easily mix some Python into your Rust code using a python!{ .. } macro. In this series, I’ll go through the process of developing this crate from scratch.

IBM Developer is the source for hands-on training and in-demand learning on relevant technologies such as generative AI, data science, Java, and more.
It's not about technology for its own sake. It's about being able to implement your ideas.

Python and Go have distinct qualities that can complement each other.
In this article of our Haskell in Production series, we interview José Pedro Magalhães from Standard Chartered – a multinational bank that has over 6 million lines of code written in their own dialect of Haskell.
