Operating Systems

Past Presentations


Why aren't operating systems more like applications?We live in an era of application microservices, even nanoservices. Each application serves precisely its purpose, living for exactly how long it needs. When we need it to do something else, we either create a distinct service, or rebuild...

Unikernels Aren’t Dead, They’re Just Not Containers

For years we’ve been observing the Unikernel concept gather and then lose steam. Unikernels where put forward as the next evolutionary step beyond containers. However, unikernels are fundamentally different beasts and they really have very little in common with containers. I’ll try to look...

Understanding CPU Microarchitecture to Increase Performance

Microprocessors have evolved over decades to eke out performance from existing code. But the microarchitecture of the CPU leaks into the assumptions of a flat memory model, with the result that equivalent code can run significantly faster by working with, rather than fighting against, the...

SQL Server On Linux: Will It Perform Or Not?

What have you been working on recently?

Two years ago there was a business decision to put SQL Server on Linux; so, as the engineering team, we have to figure out the “How” part. The task is technically challenging: tens of millions of lines of code that continues growing on a monthly basis, with over 500 developers working on it. The Drawbridge project, which I became...

What's the focus of your work today?

I'm playing in a few different areas all related around technology and operations. My focus tends to be where do changes in technology or engineering lead to fundamental changes in how individuals and companies operate. Sometimes it's a little bit more about the tech, sometimes it's a little more about operations and organization, but...
