About this event

As a bonus our venue Thames Valley Science Park has agreed to let you use their hot-desking facilities for the afternoon. So if the aim is to avoid the traffic you can now make the journey early and continue to work from there until the meetup starts. Free tea and coffee is also available :-O. It's a great chance to get a feel for what is going on at TVSP.

Note: This is currently at the fantastic new Thames Valley Science Park facility in Shinfield.

In August - Doug Sillars will be joining us as part of his European tour. On the evening, Doug will introduce some image & video optimisation techniques that we'll then go on to implement in a practical workshop.

A Google Developer Expert and the author of O’Reilly’s “High Performance Android Apps,” Doug has spoken at developer conferences in the US and Europe, and blogs regularly at He is currently working as a freelance digital nomad, traveling with his family in Europe.

Fast and Beautiful Images and Video...

The average website page weight is 50% images and 25% video. As the images and videos delivered to mobile devices get larger and larger, the load time of websites gets slower and slower. Further complicating matters, there are thousands of screens and devices with varying resolutions and CPU power that receive this content. In this talk, we’ll examine strategies to send the perfect image or video to every device, ensuring a fast, beautiful rendering of your content. We’ll look at how to test our content, and describe responsive images, delivering progressive images, and finally optimising all of this content for fast delivery to each screen. Attendees will walk away with a better understanding of how to efficiently deliver beautiful images to every device that accesses their content.

Applied Image Optimisations Workshop.

This will require a laptop and provided wifi. It'll run on any browser - and can be hosted on Github (or anywhere really). We'll apply the optimisations we covered in the talk to an actual website that is really slow.
