22: Scaling WhatsApp with Silky

<p><span style="font-weight: 400;">For the first time, Rachel and Pascal are joined by a guest from WhatsApp. Silky walks the two through a staggering array of optimisations WhatsApp deploy to make sure that text, media and documents arrive quickly, reliably and safely on the other end. They discuss going from five to six nines of reliability for Facebook’s distributed blob store, POPs, FNAs, and fighting abuse on an end-to-end encrypted platform. As ever, before the interview, Pascal and Rachel discuss some news from the Open Source world, including React Native documentation updates, an exciting contracting opportunity on the Docusaurus project and the latest Facebook Open Source statistics.</span></p> <p><span style="font-weight: 400;">Please do send us feedback!
