A public list by dan.

Anyway... the talk is done. Rehearsed a couple of times. Happy with the pace and I still have 10 - 15 minutes left for the demos that I have planned and Q&A.

Panic over.

Every time I decide to write a talk I underestimate the time I need. I do have a rough idea, but there is this whole period of me just making random slides. Sometimes weeks.

Then suddenly I am happy. Build the rest of the talk in a day or two. Way too long. Cut in half. And it just fits together.

I haven't yet made plans for speaking at conferences this fall – limited time and writing another talk kind of felt too much...

Now that the CSS Day talk is ready, I really think the CSS DOOM chapter would work really well as a standalone talk.

Hit me up in my DMs – love to talk about CSS DOOM

This weekend was full-panic mode for #cssday as I had not a single slide or even an outline. And the conference is next week.

It took a couple of days, but last night I finished it and thought I could relax again.

Did a full run-through today and I’m about 15 minutes long. Back to panic mode.

It has been such an honour to be on the Beyond Tellerrand stage. I've given dozens of talks and this one felt very much like a personal journey through some projects I never meant to show on stage.

I had so much fun creating all of this and I think it shows in the video. Thank you, Marc!

I can't believe this actually works.

The game loop sends renderer commands to an orchestrator that fans out the commands to multiple local completely independent renderers.

Each renderer gets the same commands and can decide to override the camera position.

One of the things I started doing recently is to add recording and visualisations straight into my demos. Great to export and then include in a talk.

In this case I am showing 4 different renders, from my original oscilloscope version of DOOM and several intermediate steps of the CSS renderer.

I guess this is a sign that I should start with my #CSSDay presentation 😬

@Una I might need to recount, but I think we cover 34 (!!) new #CSS and Web UI features in 45 minutes in this talk.

Every demo shown in the talk has a link, and there's also a ton of links to articles and explainers included throughout.

And yes, we also show compat tables and baseline indicators.

Here's the recording of this year's “What's new in Web UI” talk @Una and I gave at Google I/O earlier this week.

Very happy with how it went, and I think you might find it useful, so give it a watch 😊
