This week on our panel we have Jamison Dance.JAMISON:  Hello friends.CHUCK:  I’m Charles Max Wood from DevChat.TV. And we have a special guest and that is Jake Archibald.JAKE:  Hello.CHUCK:  Jake, do you want to introduce yourself for the folks who haven’t heard of you before?JAKE:  Sure thing. I work on the Google Chrome team as part of DevRel. What I’m doing there is a combination of speaking at conferences about particular stuff. I got to do a lot in performance at the moment, but I also do a lot of standards work where I’ve done a lot with an alternative to application cache, which we’ll be talking about, but also looking at things like script loading and some of the resource priority stuff.CHUCK:  Cool. So it sounds like you’re smart on a number of levels then.JAKE:  Or dumb at all. [Chuckles] I can only see what I work on. I don’t know if I’m any good at it.[Chuckles]CHUCK:  So we brought you on to talk about the application cache. I’m not completely sure I know what is totally involved there. Is it just the cache like you clear the browser cache cache or is it something else?JAKE:  Well. the aim for the application cache was to let you make a site that works offline. So we’ve got the http cache and that works, in a manner of speaking. But if you have, say a website where you’ve cached your JavaScript, you’ve cached your CSS. You’ve cached your html page and some images. That’s great, but the user will visit another website and the browser will go and delete the CSS file from your site from the cache just to make room for the stuff from this other site. That means that if we were just going to use the http cache for making things work offline, people go to your site, your html’s there, your images are there, your JavaScript’s there, but your CSS is not and that’s going to break your site.Special Guest: Jake Archibald.
