Doubly a shame, any decent tiki bar should've been well-equipped for a NA cocktail & if anything ready to go "Hey, we have this neat house thing!"

(your order was simple, but that just makes it worse for them)

p75 and p90 JavaScript bytes on the web have exploded since May, 2025—easily the largest 10 month period based on HTTP Archive data since 2023.

The long-tail is getting worse, very quickly.

Gemini, what happened in May 2025?

Daughter gently lifts the cat off the table, the cat still very much in "let me at that food" mode.

Eid Mubarak. Here is my daughter fending off a Beirut cat who belongs to the cafe but wanders in and out depending on the menu. If you celebrate, may your meal be as tempting as the makdous bi labneh was to this kitty.

Agreed. I haven't tested this yet, but Steam's clipping overlay might work? It'd be weird, but plausible

@newyorker.com hit the nail on the head with this one 😂

#Seaotters are highly intelligent marine mammals that use tools, like a rock 🪨, to crack open the hard-shelled invertebrates they love to eat, such as crabs 🦀.

Both showers and public transit rides have 3x multipliers to Thinking Time. You'd think stationary bikes would be too because they're both moving and mindless but actually they're 0.5x at best. Long flights have 10x to Thinking Time but only if you're in the sweet spot of tired but not TOO tired

Bao, meaning “treasure” in Vietnamese, represents more than a milestone for our zoo. His birth was recommended by the Association of Zoos & Aquariums Species Survival Plan® (SSP), a science-based program supporting the long-term survival of this highly vulnerable species. 2/2

Two things growing otter pup, Bao, loves: eating seafood and playing with sticks! 💙

As first-time parents, Pintar and Sebastian have done an exceptional job raising Bao behind the scenes. Now three months old, he’s ready to make his public debut this weekend. 1/2

SpeedCurve | How fast is fast enough? Rethinking web performance in pragmagical terms Always remember: We're in the business of creating experiences for other humans.

In our rush to align page speed with SEO and business metrics, have we in the #webperf community lost our way? In this post, based on the keynote I gave at #PerfNow a few months ago, I explore how it's not too late to bridge the gap between pragmatism and user delight.

How do you measure when a component is “ready”? ⏱️

LCP is too global; Element Timing is too specific.

🛠️ I’ve been working with Bloomberg on a new #webperf API: Container Timing. Think of it as “LCP for a web component”, providing aggregated paint timing for a subtree.
