Kubernetes (64 Key Concepts) 👇👇

@jasonalakiri I always agonize on what to name a variable or function

Writing code: 10 mins. Naming the variable: 45 mins

I am E. and F.

“How would you Deploy the application to Kubernetes.” 🔴 Candidate A: “I’ll create a Deployment, Service, and Ingress.” starts writing YAML 🟢 Candidate B: “Before that, can I ask a few things?” Interviewer: “Sure.” Candidate B: “Is the app stateful or stateless?” “Expected traffic?” “Any autoscaling needs?” “Do we need high availability across nodes or zones?” Interviewer: “Stateless, high traffic, needs autoscaling.” Candidate B: “Great. I’ll include HPA, resource limits, and readiness probes…” Lesson: Kubernetes is easy to deploy. Hard part is deploying it correctly.

@Amani_Thunk @X 🤝

@abdulmuhd_dev @X Hey, Looking to meet more builders in AI/ML. Let`s connect🤝

Hey @X algorithm 👋 I’m looking to #connect with people interested in: •Frontend •Backend •Databases •Full-stack •DevOps •App Development •SaaS •AI / ML •Data Science •LeetCode & DSA •Startups •Building in public •Web3/Blockchain If that’s you, let’s connect 🤝

AI Video Generation Gone Hilariously Wrong

@REjjami I totally agree 💯 Dr. @REjjami

@abdulmuhd_dev Interesting how the same tools can lead to very different results depending on the team.

The biggest driver of DevOps success isn’t tools or processes it’s CULTURE. Teams that prioritize collaboration, transparency, and trust always outperform. What’s your take?

@e_opore What about Python?

In the AI age, Java is more relevant than ever

20 ML algorithms and their real-world use cases. One cheat sheet i wish i had when i started. I spent months confusing random forest with decision trees and had no clue when to use xgboost vs lightgbm. So i made this for myself. Save this and share this with someone who's into data analytics. #machinelearning #datascience #algorithms #python #dataanalyst

Before you call Kubernetes the solution… understand the problems it was built to solve and you can use the same during interview 🔥🔥

@REjjami @X I Absolutely agree, Dr. @REjjami ! The AI + full-stack combo is a game-changer right now — being able to integrate LLMs, RAG pipelines, or AI agents directly into scalable web/mobile apps opens up so many possibilities for intelligent SaaS products.

@abdulmuhd_dev @X The combination of AI and full-stack skills is becoming increasingly valuable.

System Design Talks 25 - Stateless Auth [All FAANG Interview] Problem We're using JWTs for our app. An account is hacked, so user changes their password. But the hacker still has the JWT that doesn't expire for 1 hour. How to 'revoke' that stateless token to prevent exploits?

@techyoutbe I used openrouter.ai instead, but i can write fall back manually if needed

@abdulmuhd_dev are you using fallback as well..? for API
