Related to the recent "what-did-Chrome-do-shipping-all-these-ugly-interest-invokers-they-must-be-evil-oh-wait-no-i-think-i-have-the-experimental-flag-set" flap:
Would it be a good idea if browsers showed a clear "Experiments Engaged" message in their toolbar or somewhere if the experimental flag is engaged?
I know from my QuirksMode testing days that this can be really really tricky to remember and a big, user-friendly visual might help.

Do you want to hear the good news?
It actually works nowadays. For many many years it didn't, but since about, eighteen months or so, it does.

Or this #cssday feedback:
"Too many white people, too many men. Too many of the same people that always speak."
If you feel that way, why come at all? I mean, you could have known beforehand.

Is the email system breaking down?
Just now I went to an art gallery and a board game shop, and both proprietors complained that their mails never arrive any more.
Coming home, I discovered a mail I was expecting for days in my spam box, while there was no reason for doing so.
Is the pressure getting too high or something? It's getting impossible to mail people.

Severely censored until I can get my old schwung back.

I bought a new city bike. After a bikeless period of at least 16 months or so, maybe longer.
For the first five minutes I biked like a tourist; all kinds of navigational, Amsterdam bike dance rule-following, and collision avoidance systems had to come online from their long slumber. But it went better during the next 15 minutes of bike ride.
My muscles, unfortunately, are completely atrophied and will need a few week to reset.

Writing a CSS Day newsletter about flamethrowers and doom lasers. We must address the legitimate concerns of our audience.

Buy tickets for all of these conferences, and buy them now.
Or else @npub1la3…w653 will come after you. And you know what that means.

Well, CSS Day is live now (https://cssday.nl) and I've got a bunch of related things to do but unfortunately I'm ill and can hardly concentrate.
So the going will be very slow this time.

Home. Sleep.
No #perfnow day 3. I'm sorry.

2025-08-25 13:15:27 GMT

performance.now(), the web performance conference, 30th and 31st of October, Amsterdam. Single track, the best speakers in the industry, plenty of your performance-mad peers around to have fascinating conversations. What's not to like?

SSI is an Apache functionality, so yes, you need Apache to run locally (and then maybe mess with httpd.conf, depending on the defaults - on Mac SSI is turned off by default for God know what sort of silly reason).
This article makes it seem as if installing Apache on Windows 11 is fairly easy, but I have no experience.

I am looking for WEB DEVS to INTERVIEW about WEB MONETIZATION.
We want to understand our developer audience better, and want to know what you expect from Web Monetization, and how you expect it to work.
Want to help us? Please fill in https://docs.google.com/forms/d/e/1FAIpQLSckZ5MVzAAbQmoRjkwmjL_xlab3_OkxJrHlM8cpIdTmyKGvLA/viewform and we'll be in touch.

Not totally sure why, but we'll see.
