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 🚀

Go Channel Hell: How We Defeated chan map[string]*map[int]chan struct{}

Hey Gopher! 👋

Have you ever seen code like chan map[string]*map[int]chan struct{}? If yes, then you know what channel hell is.

This is a story about how we started simple, reached nightmare, and found an elegant solution. A real-time notification system that grew from 100 users to 100,000, and how we refactored the channel architecture.

Spoiler: we ended up replacing all this horror with 3 simple interfaces and typed channels 🚀

Test Doubles: Mocks, Stubs and Dependency Injection in Go

Hey tester! 👋

Are your tests slow, brittle, and dependent on external services? Every time the database is unavailable, half your tests fail?

Test Doubles are your salvation. Instead of real dependencies, use fakes: mocks, stubs, fakes.

Let’s break down how to properly isolate code for testing and write fast, reliable unit tests in Go 🚀

Linear Regression in Go: From Zero to Production

Hey Go developer!

📊 Think machine learning is only for Python developers? Want to add predictive analytics to your Go service but afraid of math?

While others import sklearn, you’ll learn how to implement linear regression in Go from scratch and take it to production-ready solution.

1. What is Linear Regression and Why Does a Go Developer Need It?

In simple terms

Linear regression is a way to find a straight line that best describes the relationship between variables. Like stretching a thread through a cloud of points on a graph.

Natural Language Processing: Text Processing Fundamentals in Go

Hey linguist! 👋

Want to teach computers to understand human language? Analyze customer reviews, extract keywords from documents, or determine sentiment of comments?

Natural Language Processing (NLP) is the magic that transforms unstructured text into useful data. And yes, you can do this in Go!

Let’s explore NLP fundamentals, practical algorithms, and real examples of text processing in Go 🚀

Go Race Detector: Finding and Fixing Data Races

Hey bug hunter! 👋

Data races are the most insidious bugs in concurrent programs. They hide in production, don’t reproduce locally, and corrupt data in the most unpredictable ways.

Fortunately, Go has a built-in race detector that finds these bugs automatically. It’s like an X-ray for your concurrent code!

Let’s explore what data races are, how to find them, and how to fix them using Go Race Detector 🚀

GitHub Actions: Advanced Workflows for Go Projects

Hey there! 👋

Are you still manually running tests before every commit? Deploying to production via SSH and praying nothing breaks?

GitHub Actions turns your repository into an automated machine: tests, linters, builds, deployments - all without your intervention.

But most people only use basic features. You can set up matrix testing, dependency caching, conditional deployments, and even automatic releases.

Let’s explore advanced patterns for GitHub Actions in Go projects 🚀
