In late 2017, we received some critical feedback from the brothers on the Stranger Things 2 audio mix: in some scenes, there was a reduced sense of where sounds are located in the 5.1-channel In this tech blog, we’ll dive deep into what high-quality audio is, how we deliver it to members worldwide, and why it’s so important to us.

We’re equally convinced on both counts, but in this blog article, we’re focusing on why MongoDB is not open source. This blog article traces key developments that coincided with MongoDB’s move away from open source software, and it examines how SSPL influence might have lured others in the same direction.

Back in 2014, I started a series of blog posts here to talk about specific wait types and what they do and don’t mean. Understanding what these mean and how to investigate them is critical so you don’t succumb to what I call ‘knee-jerk performance tuning’ and waste time and effort trying to fix a problem that isn’t actually a problem.

This weeks’ blog post covers a technique you can use to make all file operations on Windows run at one tenth their normal speed (or slower), in a way that will be untraceable for most users! When you own all of the code then this may involve some back of the envelope estimates, competitive benchmarking, or intuition tuned by experience.
