    The Glimmer VM: Boots Fast and Stays Fast 05 Apr '17, 8pm

    Great web applications boot up fast and stay silky smooth once they've started. In other contexts, applications can choose quick loading or responsiveness once they've loaded. Great games can get away with a long loading bar as long as they react instantly once the gamer gets going. I...
