Welcome to the Backend Engineering Show podcast with your host Hussein Nasser. If you like software engineering you’ve come to the right place. I discuss all sorts of software engineering technologies and news with specific focus on the backend. All opinions are my own. Most of my content in the podcast is an audio version of videos I post on my youtube channel here http://www.youtube.com/c/HusseinNasser-software-engineering Buy me a coffee https://www.buymeacoffee.com/hnasr🧑🏫 Courses I Teachhttps://husseinnasser.com/courses

An aws engineer discovered a 50% regression in postgres throughput while testing the new Linux 7.0 kernel. The cause turns out to be massive TLB and page faults exacerbated by Postgres process-based design. In this backe
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 ca
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
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
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. 0:
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
On October 19 2025 AWS experienced an outage that lasted over a day, 10 days later we finally got the root cause analysis and we know exactly what caused the DNS to fail0:00 Summary 5:30 How did Dynamo lost its DNS?13:41
There are cases where the backend may need to close the connection to prevent unexpected situations, prevent bad actors or simply just free up resources. Closing a connection gracefully allows clients and backends to cle

Polling is the ability to interrogate a backend to see if a piece of information is ready. It can introduce a chatty system and as a result long polling was born. In this video I explain the beauty of this design pattern
