BU BÖLÜM HAKKINDA
Page faults occurs when the process tries to access a memory that isn’t backed by a physical page kernel raises a fault which loads a page. It happens on first access, stack expansion, COW, swap and much more. However it comes with a cost.
In this episode of the backend engineering show I dissect the need and the cost page faults in the kernel.

Page tables provide the mapping between virtual memory and physical memory for each process. This means it needs to be as efficient and as fast as possible. I explore the inner workings of page tables in this episode.

I wrote a new book that has been in the works for years. It is called Root Cause, and it is for those who enjoy the art of backend engineering.
Early in my career, 20 years ago, I built backend and database applications without fully grasping their inner mechanics. Performance issues, race condit…
In this video I introduce 5 different design patterns for building backend applications. Each mode explains how a socket listener is established, a connections are established and how threads and connections are managed to read, write and process requests.
A discussion about why many engineers still love the struggle, the mistakes, and the process of figuring things out themselves. This is how we grow and get better and stronger. Letting AI do everything (even though it can’t) robs us this feeling..
