Scalability, scale-up, systems thinking, and collaboration — Hello everyone! The 55th episode of “It Depends”, my weekly newsletter on software engineering is out. This one is a doozy, even if I say so myself. Don’t miss it. This week I have put together a comprehensive look into scalability. I explain what it means, why we sometimes don’t have it, and what can we do to make scalable systems. From the internet this week, @Sander_Mak on scale up at Picnic, a comprehensive review of literature on systems thinking in engineering, and @jessitron on why we need better software, not better coordination.
