Привет, любители Go и статистики!
A/B тестирование повсюду: цвета кнопок, цены, алгоритмы. Но большинство реализаций использует частотную статистику.
Байесовский подход даёт вероятность того, что вариант лучше, а не просто “статистически значимо”.
Разберемся в деталях и реализуем это на Go.

📊 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.
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.

Need to build a notification system that works like the big players? Where messages arrive instantly on all user devices, and the server doesn’t crash under load?
Let’s break down how to design a notification service that can handle millions of users and sync state across their devices.
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 🚀
Continue readingImagine searching for your favorite song on an old mp3 player without a playlist - scrolling through tracks one by one until you stumble upon the right one. That’s PostgreSQL without indexes: huffing, puffing, and scanning every row in our huge table.
Now add indexes - and you’ve got Spotify with instant search!
Let’s quickly break down what indexes PostgreSQL has, why you need them, and how they transform your database from a turtle into a rocket. Plus - a couple of real-life examples to feel the difference.

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 🚀

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 🚀
