After a long flight and a little bit of jetlag, I've arrived back in London after visiting New York for Velocity Conference 2014. In typical Velocity fashion, the quality of the talks have been amazing and there have been a few highlights that are worth sharing. I thought it would be worthwhile to gather all the slides and links together in one place.
Extreme Mobile Web Performance
First up and definitely worth sharing is Maximilliano Firtman's talk about Extreme Web performance for the mobile web. In it, he covered all aspects related to mobile web performance and the key tips and tricks that you can use to improve your mobile websites today. The slides contain detailed demos that explain the different factors that can affect mobile web performance.
Building a device lab
The next talk worth mentioning was entitled Building a Mobile Device Lab by Lara Swanson & Destiny Montague. They both work at Etsy and gave a great account of the challenges involved in building a mobile device lab. There was a deep dive into power management, device setup and how they test at Etsy. If you or your company is interested in setting up a device lab for testing, take a look at the videos below.

Are progressive JPEGs really the best option for our user's overall happiness?
