Floating ghosts, singing pumpkins, and creatures on the house, all from three projectors in the front yard 👻🎃

The ghost screen is just gray tulle stretched on a scrap wood frame. The trick-or-treaters loved it.

Parallel test runs are great until a test changes global state, like the server date, and breaks its neighbors. I wrote up three ways to mix serial and parallel tests in #Playwright https://t.co/UUCBTgXHiy

An #AI-generated #K6 load test took 30 minutes to build and passed every check.

The app fell over in production days later. A silent try/catch had been swallowing every error the whole time.

What the #StarEast 2026 session taught me about AI guardrails: https://t.co/9jSZAqKVCQ

I reused our #Playwright functional tests to drive load testing. A SAS performance engineer did the exact same thing, independently, using different tools. Neither of us knew the other existed. We hit the same wall too.

10 years of suction-side pool cleaners never touched my walls. My new @AiperOfficial Experts Duo (Scuba + EcoSurfer skimmer) and a robot pool cleaner climbed them clean and ate every bug off the surface. Was the 2x price worth it? https://t.co/ux07zmasR4

If your attic fan or gable fan isn't matched with your soffit or ridge venting it may be costing you money instead of saving on summer air conditioning and cooling costs. Check with this intake calculator https://t.co/huh2l3Ar5m

Why does #Ubiquiti #UniFi offer such a great #5G internet backup solution lineup paired with such awful data plans? This could have been my unicorn solution. https://t.co/KI2idzoKRP

Used a #FLIR camera to see how much heat a portable #AC exhaust duct radiates back into the room it's supposed to be cooling.

The before/after after insulating it is pretty wild + #efficiency tips learned since

Have you, or someone you know, been told that #Playwright CLI is more token efficient, but haven't independently researched why? Well @AutomationPanda explained it during #StarEast2026

"What is an eval? It is a regression suite...codename because developers didn't like testers so they came up with a different name." Kevin Pyles dropped that line at #StarEast2026 🤪

I also built a Dracula chatbot. https://t.co/BhfIbi4ML3

Interesting tutorial on using AI Vision to side-step brittle test selectors at #StarEast2026 as well as using vision to test non-web apps
