When we last looked at the On the Addition of Fractions, I covered a proof that the harmonic series

Accessibility problems usually have recognizable solutions. A button needs an accessible name, text needs sufficient contrast, and a modal needs sensible focus management.

When writing React code, we often need to pull data from an API and manipulate that data to better match how we want to present it. Now that React hooks are ubiquitous, I have seen a lot of that data manipulation move into hooks that get re-used in multiple components.

We all end up doing it: // TODO implement this function, or // TODO handle this edge case. Often as we write code, we use TODOs to track ephemeral work, and typically clean them up as we go along. But sometimes we keep that TODO around, and it ends up in main. Then what?

In a previous article, I discussed Surfaces as an abstraction on APIs and how we could measure complexity as the size of that surfaces' perimeter – the "visible" part of the API to consumers. I shared this article with a colleague who I was actively working closely with on a new implementation of a design system. They has some interesting feedback on different ways of reducing complexity of certain APIs that I felt compelled to revisit this topic.

I've discussed full and partial objects before on this blog, and in this article I'm going to investigate a common factory pattern in Typescript that can lead to type-holes. When writing tests or complex components, I'll often create prop factory utilities.

We all know that naming things is right up there in the top three most difficult things about programming, right next to concurrency and caching.

At the height of the GPU craze, around 2021, when everyone was holed up in their homes due to COVID, the 30 series of Nvidia GPUs was extremely difficult to purchase. The scarcity was due to a few factors: the COVID pandemic had disrupted supply chains across the world, Taiwan was experiencing a severe drought that was impacting chip production, and cryptocurrency, especially ETH, was gaining value, making mining it was the latest GPU series incredibly lucrative.

In my previous post, "On the Addition of Fractions, by Petri Mengoli", I wrote that the following inequality holds, with no proof

In 2008, Steve Ballmer once famously said “Developers, developers, developers” in a highly meme-able video. He was trying to emphasize the importance of software developers in business and that their importance was only going to continue to grow. Microsoft shifted to try to support software developers, noticing that if they supported developers, they would build better software for Windows, which in turn would make people want to use Windows.
