we are doing a special show on 4/15 with awesome speakers and opportunities to sing (or not!)
Folks, if you’d like to give a presentation, let Jenna or myself know!
It’s like not providing laptop, internet or electricity - no point to stay in the office during blackout.
Over the past 19 years, my team @cloudfour.com have shared over 600 articles and resources with the #WebDesign community, absolutely free.
But now, our design practice is in danger without your help. Please read and share: cloudfour.com/thinks/more-...

What's next? It'll start building the ridge beam between the eyebrows?
🚫 When All You Can Do Is All or Nothing, Do Nothing
For all you weekend warriors, advice for times of uncertainty.

OK, I moved the first planet in federation to prime.federatedplanets.com and created web-inspector cli npm package to validate the planets: github.com/Federated-Pl...
We do augment it a little today, but will definitely need to either do more of it or simply get more data sources to augment it.
I am working on a standalone open source waterfall web component that we'll be also using in Telescope. It only uses HAR at this point, but would love to add other sources as well.
There is still a lot for me to clean up, but would love your opinion at some point: github.com/cloudflare/t...
Next up - building ships and space ports using some kind of distributed ledgers filed with the source and destination planets that do some kind of signing of those plans making them verifiable and useful.
Never thought I'd be researching distributed ledger technology ;)
Navigation API
Building single-page apps just got a lot more reliable with the Navigation API hitting Baseline Newly available → goo.gle/3MGV7NN
Use it to intercept navigations and manage history entries natively without the sharp edges of the legacy History API 🧭
I'm worried that they'll just chuck it out to the cost of doing business - like they already do when their sites are slow - "that's our normal conversion rate" and "we usually have that many people bounce from our inbound ad campaigns".
I absolutely LOVE that I can just tell Antigravity (in excruciating detail) that I'd like it to build a pcap/pcapng processing layer to decrypt TLS, decode DNS and extract HTTP, HTTP/2 and QUIC to a request level and I have working code in a couple of hours.
Well, what can I say - first outpots of Federated Planets is ready: federatedplanets.com - you can see how to populate your own world at Source Codia here: github.com/sergeycherny...
The latest twist is that it can use some federated protocols without any centralized authority and can be called “Fediverse Traders” or something like that. Maybe ATproto or something.
What should I do with all the ideas I get (new and well forgotten old ones) now that the barrier to get somewhere is so low?
Most recently remembered one - distributed clone of “VGA Planets” (yes I’m old) but where each planet is a website that people host on their own, customized and all that.
Time for SKILL/fast.md files
“Appeasing a RoboCop” - a process of making sure AI review bots for your PR are good with your changes.
Apple generates a helpful video for your new app’s social media.
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?
Surprise, surprise!
After a long time out, I finally re-vibed Treasure Scanner for iOS in Swift and it is now available in the App Store: apps.apple.com/us/app/treas... - it is now faster, supports light and dark modes and syncs leaderboards and achievements to Game Center.

Yep, I feel that at least interrupts the flow due to slowness of the computer response (even if masked by some clever tricks). I do find some positive feeling when machine manages to build things (that would be a routine before) faster skipping me the trouble, but overall I don’t feel that’s enough.
I wonder if anyone already did any research about the state of flow and job satisfaction for people who use AI workflows comparing to “classic” workflows.
I currently only have circumstantial feelings about it which might or might not be attributed to overall stress of the changing industry.
To me this bug, again, confirms that we need proper mobile testing of WPT.
I sure hope github.com/web-platform... can come to a conclusion this year, so that the set of viewport tests which I proposed in 2023 can finally be implemented, preventing regressions like this from happening 🤞
Had to do that a decade r so ago and quit coffee altogether - next challenge is to quit sugar, then Starbucks brand ;)
A screenshot of the video section of the HTML standard, now containing the loading attribute, a new addition
Spec proposal merged.
HTML video and audio lazy loading is now a web standard.

Kudos to @scottjehl.com (and all that helped him along the way!) for making this happen.
