🗣️ Talks
➡️ The Lost Art of Debugging: Why Your Browser is Smarter than AI - Abdullah Ola Mudathir
The easiest thing to do is often what causes hours of debugging down the line. With LLMs becoming increasingly normalized in the industry, an overreliance on them can allow bugs to slip through the cracks.
In this talk, I'll demonstrate a practical debugging workflow: Debug first. Prompt second. I'll show how browser DevTools reveal what's actually happening faster than any AI can guess.
You'll learn:- Essential DevTools features that improve your bug-fixing prowess
- When to reach for your browser and when AI can actually help
- The almost forgotten art of breakpoints and strategic console messages
AI in your codebase represents growth, but understanding your runtime state represents mastery. This talk is about balancing both and knowing which tool to reach for first.
➡️ Why Your Marketing Scripts and Cookie Banners Are Ruining Your Lighthouse Scores - Christopher Burns
Most marketing scripts and cookie banners run on the critical path. They block the main thread, delay first paint, and inject third-party code before the page is interactive.
Consent managers often make this worse by synchronously loading vendors, mutating the DOM repeatedly, and re-hydrating UI after page load. The result is slower LCP, higher TBT, and unstable CLS.
The fix is not fewer scripts, it is better orchestration. Treat consent as infrastructure, load vendors after intent, and keep compliance off the critical path.
