The Backend Engineering Show with Hussein Nasser

In this video I give some advice to junior backend engineers who just started their new jobs and feel overwhelmed. Backend engineering jobs can be overwhelming at the start, there are so much to learn, so much to read, documentation, tests, code in multiple programming languages. Here are some advice for Junior backend engineers. 0:00 Intro 1:20 Take your time 6:05 Stay hungry keep learning 8:36 Assume your collages know something you don’t 12:42 Don’t bad mouth other people code even if its bad 17:19 Question everything

Creating a software design is an art here is why 

Qualities of a good software tester: understanding the system being tested, strong troubleshooting skills, finding unexpected bugs. Approaches to bug finding: investigating underlying cause, using proxies, identifying UX bugs. Importance of testing and how to excel: dig deeper into server and database, analyze CPU and database performance.

JSON Web Token (JWT, sometimes pronounced JOT) an internet standard for creating JSON-based access tokens that assert some number of claims. The tokens are signed either using a private secret or a public/private key. In this video I want to discuss the difference between JWT and Session Based Auth, will show examples with Node JS and Postgres. Finally I’ll discuss the pros and cons of JWT.

This podcast explores the main differences between synchronous execution, multithreading, and multiprocessing programming. It discusses the advantages and disadvantages of each approach and touches on topics like thread blocking, asynchronous execution, thread safety, inter-process communication, and problem-solving among multiple processes.

In this video I explain End to End encryption within the context of WhatsApp. I explain how encryption and TLS works then the problem of having a centerlized server decrypting the traffic, I then talk about how end to end encryption (e2e) can help mitgate that and finally I explain the problems with e2e encryption Classic Encryption Example 1:00 End to end encryption 3:25 Problem with E2E 7:30 - Trust? Fingerprints/CA (QR whatspp) encryption 00:30 encryption, e2e encryption, end to end encryption, whatsapp end to end encryption, how e2e works, e2e limitations

WhatsApp Introduced long time a go Unlimited forwarding then limited Up to 5 times Double forwarded too many times (last year) Double forwarded messages can only be forwarded once or even none Forwarding feature end to end encryption Sent/delivered/read https://www.cnbc.com/2020/04/07/whatsapp-limits-message-forwards-to-combat-coronavirus-misinformation.html

In this video, I explain the difference between a proxy and a reverse proxy. This is a refreshed version of the proxy video I made.   What is a Proxy ?  Proxy use cases - Logging - Anonymity - Geofencing  - Caching - Block sites (office)  - Enable Polyglot    What is Reverse Proxy?  Reverse Proxy Example Reverse Proxy Use Cases  - Caching (Varnish)  - Load Balancing - Ingress (/pics)  - Canary Deployment   Many types of proxy check it here  Q and A * can we use proxy and reverse proxy together?  * Can I use Proxy to hide my identity instead of a VPN?  * Can I use proxy just for HTTP?     tags: proxy vs reverse proxy, reverse proxy benefits, what is a reverse proxy, what is a proxy, what is the difference between proxy and reverse proxy   Sidecar proxy 4:14 Load balance 7:40  Proxy Reverse Proxy 5:00   🏭 Software Architecture Videos https://www.youtube.com/playlist?list=PLQnljOFTspQXNP6mQchJVP3S-3oKGEuw9  💾 Database Engineering Videos https://www.youtube.com/playlist?list=PLQnljOFTspQXjD0HOzN7P2tgzu7scWpl2  🛰 Network Engineering Videos https://www.youtube.com/playlist?list=PLQnljOFTspQUBSgBXilKhRMJ1ACqr7pTr  🏰 Load Balancing and Proxies Videos https://www.youtube.com/playlist?list=PLQnljOFTspQVMeBmWI2AhxULWEeo7AaMC  🐘 Postgres Videos  https://www.youtube.com/playlist?list=PLQnljOFTspQWGrOqslniFlRcwxyY94cjj  🚢Docker https://www.youtube.com/playlist?list=PLQnljOFTspQWsD-rakNw1C20c1JI8UR1r  🧮 Programming Pattern Videos  https://www.youtube.com/playlist?list=PLQnljOFTspQV1emqxKbcP5esAf4zpqWpe  🛡 Web Security Videos https://www.youtube.com/playlist?list=PLQnljOFTspQU3YDMRSMvzflh_qXoz9zfv  🦠 HTTP Videos https://www.youtube.com/playlist?list=PLQnljOFTspQU6zO0drAYHFtkkyfNJw1IO  🐍 Python Videos https://www.youtube.com/playlist?list=PLQnljOFTspQU_M83ARz8mDdr4LThzkBKX  🔆 Javascript Videos  https://www.youtube.com/playlist?list=PLQnljOFTspQWab0g3W6ZaDM6_Buh20EWM  👾Discord Server https://discord.gg/CsFbFce  Support me on PayPal https://bit.ly/33ENps4  Become a Patreon https://www.patreon.com/join/hnasr?  Stay Awesome, Hussein

In this video I explore what is a distributed transaction but first I explain what is a transaction, then why we invented distributed transactions and finally discuss proposed solutions to implement distributed transactions   Cards 2:40 ACID https://www.youtube.com/watch?v=pomxJOFVcQs 7:30 Microservices https://www.youtube.com/watch?v=T-m7ZFxeg1A    Transactions 2:30 Compensating Edits 6:40 Atomic Clocks 11:50 Event Sourcing 13:30 Mini-Monolith 15:20   Resources  https://www.youtube.com/watch?v=YPbGW3Fnmbc  https://www.youtube.com/watch?v=S4FnmSeRpAY  https://www.youtube.com/watch?v=epOLEdaPSLQ  https://softwareengineeringdaily.com/2018/12/19/linkerd-service-mesh-with-william-morgan/     🏭 Software Architecture Videos https://www.youtube.com/playlist?list=PLQnljOFTspQXNP6mQchJVP3S-3oKGEuw9  💾 Database Engineering Videos https://www.youtube.com/playlist?list=PLQnljOFTspQXjD0HOzN7P2tgzu7scWpl2  🛰 Network Engineering Videos https://www.youtube.com/playlist?list=PLQnljOFTspQUBSgBXilKhRMJ1ACqr7pTr  🏰 Load Balancing and Proxies Videos https://www.youtube.com/playlist?list=PLQnljOFTspQVMeBmWI2AhxULWEeo7AaMC  🐘 Postgres Videos  https://www.youtube.com/playlist?list=PLQnljOFTspQWGrOqslniFlRcwxyY94cjj  🚢Docker https://www.youtube.com/playlist?list=PLQnljOFTspQWsD-rakNw1C20c1JI8UR1r  🧮 Programming Pattern Videos  https://www.youtube.com/playlist?list=PLQnljOFTspQV1emqxKbcP5esAf4zpqWpe  🛡 Web Security Videos https://www.youtube.com/playlist?list=PLQnljOFTspQU3YDMRSMvzflh_qXoz9zfv  🦠 HTTP Videos https://www.youtube.com/playlist?list=PLQnljOFTspQU6zO0drAYHFtkkyfNJw1IO  🐍 Python Videos https://www.youtube.com/playlist?list=PLQnljOFTspQU_M83ARz8mDdr4LThzkBKX  🔆 Javascript Videos  https://www.youtube.com/playlist?list=PLQnljOFTspQWab0g3W6ZaDM6_Buh20EWM  👾Discord Server https://discord.gg/CsFbFce  Support me on PayPal https://bit.ly/33ENps4  Become a Patreon https://www.patreon.com/join/hnasr?  Stay Awesome, Hussein
