Harry Roberts - From Milliseconds To Millions: A Look At The Numbers Powering Web Performance
Harry reconvened the conference after lunch with a talk about the business impact of performance on the web. A sidestep from his usual talks about the more technical details of how to make sites fast, and he detailed some of the reasoning and methods for working to improve performance across the board.
He also went into a bit of detail about how he runs his business as a Front-end Architecture and Performance Engineer.

There's a fair amount of content on performance and CSS on his blog too.
Anna Migas - Effortless Performance Debugging
Following on with the performance theme, Anna took a deeper dive into debugging and improving performance issues. Jumping straight into a live demo with the Chrome dev tools, Anna showed off a few tips and optimisations that we can all make to ensure our pages are more responsive and usable.
I learnt about
font-display: swap; too, which I immediately implemented on this site, so thanks, Anna!
Charlotte Dann - Taking The Web Off The Screen
Charlotte is from a creative background, having studied the intricacies of Jewellery at university, but has since gone on to use code to create generative art.
There was also a great example of pen plotting in action.
Suz Hinton - Adventures In Reinventing Interfaces
Suz completely caught us all off guard when she went further into how IoT devices hijacking public radio frequencies is a real threat to our privacy in a surveillance state. She finished with a strong plea for us to be more mindful of what we install in our homes, and what giving up that privacy really costs us. Suz's talk was also a nice link into Laura's talk earlier in the day.
Less mass-produced surveillance bullshit and more Harry Potter magic (please).
I also learnt about The Every Day Calendar which is the best streaks implementation I've ever seen!
