Quantum Computing Basics: Qubits and Superposition in Go

Hey there! 👋

While everyone’s talking about AI, real geeks are already studying quantum computing. This isn’t science fiction - it’s the mathematics of the future that will break all modern cryptography.

Google claimed quantum supremacy, IBM launched cloud quantum computers, and Microsoft is investing billions in quantum technologies.

But how does it work? And can we simulate quantum computing in Go?

Let’s explore qubits, superposition, and quantum gates with practical Go examples 🚀

mTLS in Microservices: Mutual Authentication

In traditional HTTPS, only the server proves its identity with a certificate. The client remains anonymous. But in microservices, where services communicate with each other, we need mutual trust. This is where mTLS (mutual TLS) comes in.

How to Make Technical Decisions in Product Teams

Hey there! 👋

You’re not just a coder - you’re an architect of the future. Every technical choice you make is either a breakthrough or tech debt for the next year.

But here’s the problem: there are tons of opinions around, deadlines are burning, and your decision determines whether the product will soar or crash at launch.

Let’s figure out how to make technical decisions quickly, confidently, and without the subsequent “what the #@!^? did I choose?”

A guide for those who don’t want to shoot themselves in the foot

Project Crisis: How Not to Panic and What to Do

Hey captain! 🚨

Project is on fire, deadline in a week, but only 30% is ready? Key developer got sick, production crashed, and the client demands explanations?

Project crisis is not the end of the world. It’s a test of professionalism. Right actions in the first hours of crisis determine whether it becomes a catastrophe or valuable experience.

Let’s break down the step-by-step algorithm for crisis management in IT projects 🚀

Consistent Hashing: The Math Behind Load Balancing

Hey there! 👋

Imagine: you have 1000 servers and millions of requests. How do you distribute load evenly so that adding a new server doesn’t require rehashing everything?

Regular hash(key) % servers becomes a disaster when scaling. Add one server and 90% of data needs to be moved!

But there’s an elegant solution: Consistent Hashing. The mathematics that saves you from chaos in distributed systems.

Let’s dive into the algorithm used by Amazon DynamoDB, Cassandra, and Redis Cluster 🚀

TLS 1.3: What Changed and How to Migrate

Hey defender! 👋

TLS 1.3 isn’t just another protocol version. It’s a revolution in internet security: faster, more secure, simpler.

But migrating from TLS 1.2 isn’t just updating a config. You need to understand what changed, what will break, and how to migrate properly.

Let’s explore key TLS 1.3 changes, practical examples, and a step-by-step migration plan 🚀

PostgreSQL Random Data Generation

Hey developer! 🎲

Need to generate promo codes for a campaign? Create a million test users? Or just mask production data for development? PostgreSQL can do much more than just SELECT random().

Let’s explore how to turn PostgreSQL into a random data generator for real-world tasks.
