Hey! I'm David, cofounder of zkSecurity and the author of the Real-World Cryptography book. I was previously a crypto architect at O(1) Labs (working on the Mina cryptocurrency), before that I was the security lead for Diem (formerly Libra) at Novi (Facebook), and a security consultant for the Cryptography Services of NCC Group. This is my blog about cryptography and security and other related topics that I find interesting.

Long polling and webhooks posted April 2014

I remember reading about how the newly facebook chat was made using long pollings, years ago. Now with HTML5 with have sockets and webhooks made easy. I wonder if they're still using long polling now...

Anyway, Zapier. A start up that is making APIs easy, is writing a lot of interesting tutorials these last few months. Their new Chapter 7 was released and it's about polling and web hooks. And as usual it's great!
