6:30pm — Doors open, food, networking

7:00pm — Siena Aguayo: Facebook Sharing for Single-Page Apps

Facebook uses the OpenGraph tags defined on your page to populate its share dialogs. But what if you have a single-page app and you want to share many different pieces of content that technically have the same URL? Learn this One Weird Trick for sharing your beautiful content.

7:15pm — Neeraj Singh: Towards Secure Cookies with the Help of Modern Encryption Techniques in Rails 5.2

Rails 5.2 adds support for encrypting cookies using modern techniques such as AES-GCM scheme. Because of this, the authentication and encryption processes will be processed together, improving the speed of the process. Apart from that, it will also result into shorter ciphertexts resulting into quicker encryption and decryption.

Along with this, we will also discuss changes to the MessageEncryptor such as switching to AES-GCM as default cipher, better support for expiry of messages, and fine-grained server side control for the expiration of such messages.

7:45pm — Ginny Fahs & Mark Stewart: Tech: The Most Welcoming Community In The World

What if the tech community felt more like a knitting circle? This talk is about finding “the good parts” of the tech community—whatever that means for you—and empowering you to create the amazing tech community you deserve. We will trace the qualities that we believe make communities welcoming, and propose community-building strategies for those joining tech, and those seeking to improve it.

8:15-9:00pm — More hanging out and talking to nice people
