Censoring secrets from logs in infrastructure as code

15 Oct 2025 🔖 devops 💬 EN

This is not exhaustive, but here’re a few coding hygiene tidbits for making sure that when you need to use a secret in your infrastructure as code (IaC), it doesn’t leak into its execution runtime’s system logs.

Test-driven development for infrastructure as code

15 Oct 2025 🔖 devops 💬 EN

Much as I’m hooked on it, I’ll admit test-driven development (TDD) has a reputation for being a bit intimidating to adopt in traditional software application development.

Luckily, it’s not just easier, but arguably almost tailor-made for the work of sysadmins taking on the challenge of infrastructure as code (IaC).

Infrastructure as code tool types

Lately, I’ve been studying industry-standard taxonomies for categorizing the many types of tool that a company needs if its wants to modernize delivering and managing servers using “infrastructure as code.”

So far, I’m at 15 categories.

Note: my examples are probably pretty inaccurate. I’m not a sysadmin, I’ve just been researching with GenAI and picking sysadmins’ brains, and potentially not very effectively. Please take this post with a grain of salt.

Notes from Designing Content Authoring Experiences

03 Oct 2025 🔖 web development 💬 EN

I work in tech. That means that for friends and family, I sometimes find myself fixing printers and making business web sites. Greg Dunlap’s new book “Designing Content Authoring Experiences” is a resource I wish I’d had available to me over the last two decades.

Look, ma, I'm a language teacher!

I shared yesterday’s LLM prompts for requirements analysis and project scoping post with a friend, and they said:

“You got to teach languages this week!”

I teared up, and nearly dropped what I was holding, when I read that comment.

E2E and Synthetic Testing Considered Harmful

“End-to-end test automation and synthetic monitoring considered harmful” – was I clickbaitey enough to get your attention? 😉

Frontend automated testing demystifier

07 Jul 2025 🔖 web development 💬 EN

When it comes to authoring automated test code for web application frontends, it’s easy to get confused about what kinds of test go where in the “testing pyramid” and how to implement them – especially since all four levels of the “testing pyramid” potentially ask the question: “does this HTML/DOM element exist in this condition?”.

Can usability testing be automated?

07 Jul 2025 🔖 web development prompt engineering 💬 EN

Is there a place for browser automation (e.g. Playwright, Selenium, Puppeteer, Cypress) in the art of “usability testing” (à la Don’t Make Me Think)? Or should 100% of usability testing always execute on the platform known as “humans”? 😉

When I make a web site, the programming language I choose is typically Node.js (a flavor of JavaScript that can run on a server operating system’s (“OS”) command line (“CLI”), rather than needing to run inside of a web browser). I’ve played around a bit with Python, C# (via .NET), PHP (via WordPress), and Ruby (via Jekyll), but that’s about it. Despite years of Java-like programming experience via Salesforce’s Apex, I’ve never built a web site from scratch using Java.
