Performance tips & tricks
For our October meetup we are pleased to welcome the front-end team from Flickr presenting for us various tips and tricks to build high performance websites!
We'll have 3 talks:
Using Web Workers for fun and profit: parsing EXIF in the client (Chris Berry (https://twitter.com/christopher_b)) Exif, exchangeable image file format, describes various sets of metadata stored in a photo. Really interesting metadata, like image titles, descriptions, lens focal lengths, camera types, image orientation, even GPS data! I'll go over the methods to extracting this data on the front-end, in real-time, using web workers.
The Grid: How we show 10,000 photos on a page without crashing your browser (Scott Schiller (https://twitter.com/schill)) Flickr's latest Web-based Uploadr interface uses HTML5 APIs to push bytes en masse. Its real power, however, is the UI which enables users to add and edit the metadata of hundreds of photos while they are uploading in the background.
Handling the selection, display and management of large numbers of photos in a browser UI meant that the Uploadr project needed to be designed for scalability from the ground up.
This talk will go into some of the details of the Uploadr "Grid" UI,
technical notes and performance findings made during its development.
