The Backend Engineering Show with Hussein Nasser

Scientists at the Physics and Engineering Department of the UK’s Lancaster University published a new paper describing ULTRARAM. A Low-Energy, High-Endurance, Compound-Semiconductor Memory on Silicon. I think this tech is a game changer but I still have my doubts. Let us discuss 0:00 Intro 0:30 RAM 4:00 SSD 11:00 UltraRAM 17:30 Doubts * RAM (Dynamic RAM) * Fast access with capacitors * random access * requires power to be refreshed * Flash NAND (SSD) * Pros fast random access (FTL) * Block storage * Requires high voltage (20V to erase/ 7.5 to program) * Low durability endurance which then (write amplification + garbage collection ) * UltraRAM uses a new novel approach to the memory cell design that only need 2.5 V to program/erase, low power which saves the memory cell lifetime https://www.sciencedirect.com/topics/engineering/fowler-nordheim-tunnelling * High endurance program/erase last longer * High retention * GC/WA not required * Limitations: still we know very little https://onlinelibrary.wiley.com/doi/10.1002/aelm.202101103

enom my DNS registrar had an outage which took down my site husseinnasser.com lets discuss   0:00 Intro  5:00 How DNS Works 12:00 Outage report 16:00 Will I migrate my DNS? 21:40 Does decentralize mean anything anymore?

In this episode of the backend engineering show, I’ll discuss the low code movements and their pros and cons. 0:00 Intro 2:00 Evolution of Languages 8:40 Low Code Movement 10:00 Side Effect of Low Code 13:00 Leaky Abstractions Fundamentals of Database Engineering udemy course (link redirects to udemy with coupon) https://database.husseinnasser.com Introduction to NGINX (link redirects to udemy with coupon) https://nginx.husseinnasser.com Python on the Backend (link redirects to udemy with coupon) https://nginx.husseinnasser.com

These are some fundamental technologies that I want to explore in 2022.   0:00 The Way I learn 4:20 Database Engineering 7:00 Network Engineering  9:30 Hardware and Operating Systems 15:00 The problem with software engineering   Collateral Knowledge Video https://www.youtube.com/watch?v=6YKbVpWmeLM&t=3s  Become a Member on YouTube https://www.youtube.com/channel/UC_ML5xP23TOWKUcc-oAE_Eg/join 🔥 Members Only Content https://www.youtube.com/playlist?list=UUMO_ML5xP23TOWKUcc-oAE_Eg  Fundamentals of Database Engineering udemy course (link redirects to udemy with coupon) https://database.husseinnasser.com Introduction to NGINX  (link redirects to udemy with coupon) https://nginx.husseinnasser.com Python on the Backend (link redirects to udemy with coupon) https://nginx.husseinnasser.com

Welcome to another dev tools video, in this video I use dev tools to break down how Tiktok website works to pull short-form content.  We will use therock as a subject. It is an interesting episode, enjoy   

In this episode of the backend engineering show, I explain the journey of an HTTP request that gets initiated from a click on a link. I discuss DNS, TCP, API Gateways, reverse proxies, load balancers, backend web servers, and much more.
