I was recently listening to one of my go to podcasts, A Problem Squared, where the hosts tackled the problem of figuring out the probabilities of outcomes for a particular card game. They approached it by simulating the game 10 millions times and collecting statistics on the results. I've been wanting a small Rust project to work on, so I thought it would be fun to do this in Rust and run 1B+ simulations to see how the results compared. I learned far more than I expected.

One of Rust’s most powerful features is its ownership model, which enforces memory safety and helps prevent bugs related to side effects. In this post, we’ll explore how Rust’s function signatures make side effects explicit—or impossible—by design, and compare this to common patterns in other languages where side effects are often hidden.

I've been using TypeScript more and more lately. And I don't like it. I've found that I spend more time fixing type mismatch errors than I save by having a strongly typed variant of JavaScript. However, I am commonly in the minority opinion among my teams. In this article, I'll explore why that is, how to better leverage TypeScript's typing system rather than treating like annotations on top of Javascript, and I'll go through some hands-on examples based on a few real-world cases we recently encountered.

In this article, we'll discuss authentication flows in OpenID Connect (OIDC). We'll work through a hands-on example using Keycloak to demonstrate how OIDC works in practice. More information on Keycloak's authorization flows can be found here or in the OIDC Spec.

APIs or Application Programming Interfaces are, like their name implies, an interface to an application that allows other systems to interact with them programmatically. In this post, we'll discuss some foundational concepts and distill the lexicon associated with APIs into tangible knowledge.

In preparation for our upcoming pilot bootcamp, I've been working on a few programming challenges. Since we're challenging our bootcamp participants to learn a new language as part of this effort, I thought I'd do the same and finally begin exploring Rust.

Regardless of discipline, many fields need to be able to process, manipulate, and visualize data. This article introduces the basics of plotting data with Python using Matplotlib. View the notebook on Github or experiment with it yourself on Google Colab.

In this article, we discuss asynchronicity in Javascript, its evolution over time, and some of the patterns for dealing with various asynchronous challenges. We'll discuss callbacks, promises, and the present-day async/await approach to asynchronicity and when and how each of these are relevant in modern applications.

In this article we'll build on my previous article, Web Development Basics with Python & Flask and introduce the Javascript language and the concept of asynchronous communication with a webserver to provide a clean and dynamic user experience.

This article describes a recent bug in Facebook's Docusaurus project. I was not the first to discover this bug, nor was I the one to ultimately fix it, but it makes for a very interesting deep dive into how to triage and resolve an issue.
