Show Notes Welcome to The Modern .NET Show! Formerly known as The .NET Core Podcast, we are the go-to podcast for all .NET developers worldwide and I am your host Jamie "GaProgMan" Taylor. In this episode, I spoke with Niels Rasmussen about a CSV parser he wrote called Sep - one of the fastest CSV parses in .NET - and the the mysteries of performance optimization and mechanical sympathy. "And I just got hooked by it. It has to be faster. It has to be faster than the fastest known to man. So that's what I worked on a lot and that's what I find fun. I'm very passionate about performance, mechanical sympathy, all that. That's really what I dig, things I read about and stuff like that." — Niels Rasmussen Along the way we discuss the power of simplicity, the importance of understanding hardware intricacies, and the birth of Niels' lightning-fast CSV parsing library, Sep. From exploring different programming paradigms to dissecting the legendary Doom source code, this podcast is a must-listen for developers seeking to enhance their skills and unravel the secrets of software development In preparation for this episode, Niels actually provided a veritable cornucopia of performance-related stuff - from important points to links to blog posts and other resources. There was no way that we could include them all in this episode, so I have gotten his permission and have been able to supply them as a PDF, linked at the end of the show notes page on the website. How cool is that! So let's sit back, open up a terminal, type in dotnet new podcast and we'll dive into the core of Modern .NET.
