@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 🦀. #otters #cartoon #newyorkermagazine #seaotter #newyorker

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

Breaking News: Baby Bao found another stick! The 3-month-old otter pup was really proud to show it off and even share it with his mom, Pintar. 💙

Interested in the @httparchive.org and not sure where to start? During the @performanceobserver.dev meetup tomorrow (12:30pm ET), I'm going to be providing an overview of the HTTP Archive and demonstrate how to start querying it! performanceobserver.dev/events/episo...

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

How it started: early construction taking shape. How it’s going: a fully connected 2 Line. Years of planning, precision, and teamwork are leading to one historic connection, opening March 28. See more photos: https://www.soundtransit.org/blog/platform/then-now-crosslake-connection-journey-photos

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. www.speedcurve.com/blog/fast/

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.

A shocking 8.5% of sites that use CDNs deliver some static content directly to end users via cloud storage! Many are not compressing or caching this content either. This comes at a significant performance cost. Details, examples and @httparchive.org stats here - paulcalvano.com/2026-02-09-s...

"We would have lost so much if we'd driven him away" is the justification. But we lost all those girls. We lost the women they would have become. We lost the work they would have done. Why was his future work so much more valuable than theirs?

Here's your friendly reminder that CSS selectors are global and evaluated RTL, so if you have selectors that are very broad like `.container > div` you might be impacting performance in a measurable way 🙈 Before and after profile of server switching after some selector optimizations in @discord.com

this is truly a perfect distillation of the AI industry's ever-more-monumental public relations problem

Showing cross-racial solidarity is a potential death sentence. There are few things white supremacists hate more.

We could talk about whether we got the "good cyberpunk" but what's important I think is a good 50 years of film and comics were trying really, really hard to make you think about this exact sort of image, and to internalize that if you saw this sort of image you should have an intense reaction to it

The 2025 Web Almanac by HTTP Archive has been officially released! 🚀 We would like to thank all of our contributors from around the globe who made this extensive report possible! Check out the full report here: almanac.httparchive.org

I've been running an indie games studio for 15 years now, and it felt like a good time to boil down what I've learned into 4 pieces of advice: www.pentadact.com/2026-01-08-1... I hope it's of use, not least because goddamn I forgot how long blog posts take to write.

“It’s about being full human beings and not just means to an end. I want to live in a city that honors what you’re doing when you’re not making money: time spent on the playground with a kid or visiting a sick friend…we need bread, but we need roses too.” -Seattle Mayor Katie Wilson

The viewers are encouraged to take pieces of candy away, symbolically performing a sacrament of partaking of the body, and symbolically watching his partner waste away to nothing. It is such a poignant and powerful piece

My contribution to this years Web Performance Calendar is all about Third Parties and Single Points of Failure (SPOF). Based on @httparchive.org data I found that 67% of websites have at least 1 render blocking third party - and quite a few of them are SPOF risks!

What do I mean when I say everything in Obsidian should feel instantaneous? No more than 0.1 seconds. The target was established in 1968 by Robert Miller and well described in 1993 by Jakob Nielsen here:

I don't know what to say about this garbage vote to criminalize gender affirming care btw. Been trying to find the words. I hear so many friends in sadness and fear today but of what use is "I hear you"? Not much I fear. To live through this moment sucks ass (negative). We must find a way through

Got inspired

I understand that a lot of folks have been misled by fear-mongering and powerful regressive voices but it’s still astonishing to me that so many have fallen for the idea that oppressively policing other people’s gender identity and expression could in any way be part of an enlightened future.

Found the coolest website that takes random found cassette tapes people submit and digitizes them. I’m listening to an NYC hip hop station from 1994: intertapes.net

This's exciting to see, I'm glad LCP/INP are arriving. I'll be curious to see how full cross-browser comparisons of these perf metrics shake out

WASHINGTON AND OREGON CARTOONISTS: Seattle's bus service is commissioning 6 artists for public art pieces, 2 each, of local stories, 16-32 pages, over 2026, for $54k per artist, to be freely distributed over their ridership. details here: www.4culture.org/grants/movin...

macbeth linkin park what i've done

Video of my @perfnow.nl keynote is up! In this talk, I challenged the false choice between magic and pragmatism. Don't settle for "fast enough". Instead, aim to create a user experience that's #pragmagical — blending user delight with measurable business impact. conffab.com/presentation...

"babies are born worshipping unknown gods" is one of the most incredible dwarf fortress bugs i have heard of. its poetry.

Look folks gen AI videos are out in the wild so if you weren't already being careful about sharing rage bait videos then now is a great time to start If you can't trace a video back to a trusted source then I recommend leaving it where it is, like a slice of bologna you found on the street
