That is correct, the page speed insights extension has been deprecated since May 2015. We will use the online service (and api) in the talk.

You can use any preferred text editor as long as you can edit html, css, and javascript files.

Looking forward to meeting everyone in person!

Two questions about prep work:

> Google Chrome with Google PageSpeed extension installed

https://developers.google.com/speed/pagespeed/insights_extensions says “PageSpeed Insights for Google Chrome has been deprecated. Please use the online version of PageSpeed Insights.” Is that what this referred to, or is there something else we need?

> Sublime text or textmate

Can we use another favorite text editor, or will we specifically need one of those two?

Thanks! Looking forward to it.
