"Quand on parle des performances web, on peut risquer de trop idéaliser les conseils et bonnes pratiques. Cédric Morin vous propose cette semaine un article pragmatique qui vous aidera à mettre tout ceci en perspective, et à mieux gérer l'optimisation de vos sites."

At Bugsnag we use SPDY on our production rails application. For our users who run modern browsers, this can make the site feel much faster and more responsive. Want to get SPDY working on your production rails app? Read on. What is SPDY?
