This post describes how the Netflix TVUI team implemented a robust strategy to quickly and easily detect performance anomalies before they are released — and often before they are even committed to the codebase.

I rather like Scott’s term for what happens when you use client-side JavaScript for A/B testing.

This pattern leads to such a unique effect on page load that at last week’s Perf.Now() Conference, I coined a new somewhat tongue-in-cheek performance metric called “Second Meaningful Content,” which occurs long after the handy First Meaningful Content (or Paint) metric, which would otherwise mark the time at which a page starts to appear usable.

I love companies that are as invested in giving back to the community as they are at doing quality web-work. The Guardian is certainly one of them, and their latest post is a great example. They walk through several errors and mistakes they made on their site this year, why those mistakes were made, and how they fixed them.
