Many years ago, I used to think that A/B tests were foolproof and all you need to do is compare the metrics for the two groups. The group with the highest conversion rate wins, right?

It's hard to write code for computers, but it's even harder to write code for humans

Writing code for a computer is hard enough. You take something big and fuzzy, some large vague business outcome you want to achive. Then you break it down recursively and think about all the cases until you have clear logical statements a computer can follow.

Predicting solar eclipses with Python

As I am en route to see my first total solar eclipse, I was curious how hard it would be to compute eclipses in Python. It turns out, ignoring some minor coordinate system head-banging, I was able to get something half-decent working in a couple of hours.

Simple sabotage for software

CIA produced a fantastic book during the peak of World War 2 called Simple Sabotage. It laid out various ways for infiltrators to ruin productivity of a company. Some of the advice is timeless, for instance the section about “General interference with Organizations and Production”:

What I have been working on: Modal

Long story short: I'm working on a super cool tool called Modal. Please check it out — it lets you run things in the cloud without having to think about infrastructure. Scaling out, scheduling, containerization, using GPUs, setting up webhooks, and all kinds of other stuff.

We are still early with the cloud: why software development is overdue for a change

This is is in many respects a successor to a blog post I wrote last year about what I want from software infrastructure, but the ideas morphed in my head into something sort of wider.

This Arduino device helps ‘split the G’ on a pint of Guinness

Guinness is one of those beers (specifically, a stout) that people take seriously and the Guinness brand has taken full advantage of that in their marketing. They even sell a glass designed specifically for enjoying their flagship creation, which has led to a trend that the company surely appreciates: “splitting the G.” But that’s difficult […] The post This Arduino device helps ‘split the G’ on a pint of Guinness appeared first on Arduino Blog.

Why Website Taxonomies Drift (and What to Do about It)

AI is everywhere, but most websites are still managed manually by humans using content management systems like WordPress and Drupal. These systems provide means for tagging and categorizing content. But over time, these structures degrade. Without vigilance and maintenance, taxonomies become less useful and relevant over time. Users struggle to find stuff. Ambiguity creeps in. Search results become incomplete and unreliable. And as terms proliferate, the team struggles to maintain the site, making things worse. The site stops working as well as it could. Sales, engagement, and trust suffer. And the problem only gets worse over time. Eventually, the team embarks on a redesign. But hitting the reset button only fixes things for a while. Entropy is the nature of things. Systems tend toward disorder unless we invest in keeping them organized. But it’s hard: small teams have other priorities. They’re under pressure to publish quickly. Turnover is high. Not ideal conditions for consistent tagging. Many content teams don’t have governance processes for taxonomies. Folks create new terms on the fly, often without checking whether similar ones exist. But even when teams have the structures and processes needed to do it right, content and taxonomies themselves change over time as the org’s needs and contexts evolve. The result is taxonomy drift, the gradual misalignment of the system’s structures and content. It’s a classic “boiled frog” situation: since it happens slowly, teams don’t usually recognize it until symptoms emerge. By then, the problem is harder and more expensive to fix. Avoiding taxonomy drift calls for constant attention and manual tweaking, which can be overwhelming for resource-strapped teams. But there’s good news on the horizon: this is exactly the kind of gradual, large-scale, boring challenge where AIs can shine. I’ve worked on IA redesigns for content-heavy websites and have seen the effects of taxonomy drift firsthand. Often, one person is responsible for keeping the website organized, and they’re overwhelmed. After a redesign, they face three challenges: Implementing the new taxonomy on the older corpus. Learning to use the new taxonomy in their workflows. Adapting and evolving the taxonomy so it remains useful and consistent over time. AI is well-suited to tackling these challenges. LLMs excel at pattern matching and categorizing existing text at scale. Unlike humans, AIs don’t get overwhelmed or bored when categorizing thousands of items over and over again. And with predefined taxonomies, they’re not as prone to hallucinations. I’ve been experimenting with using AI to solve taxonomy drift, and the results are promising. I’m building a product to tackle this issue, and looking implement the approach in real-world scenarios. If you or someone you know is struggling to keep a content-heavy website organized, please get in touch.
