Strategy Pattern in Go: Choosing Algorithm at Runtime

Strategy Pattern is a way to choose an algorithm at runtime. Instead of hardcoded logic, you get flexibility: the same code works with different algorithms that can be changed on the fly.

Imagine a navigator: you can choose a route - fast, short, or scenic. The navigator doesn’t change, only the route-building strategy changes.

Proxy Pattern in Go: Access Control and Resource Management

Proxy pattern provides a surrogate or placeholder for another object to control access to it. It acts as an intermediary, adding functionality without changing the original object.

Here’s when and how to use it in real-world Go applications.

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 🚀

Builder Pattern in Go: Step-by-Step Construction of Complex Objects

Builder pattern separates object construction from its representation. It allows creating different representations of an object using the same construction process.

Here’s how to implement it properly in Go with real-world examples.

Observer Pattern in Go: Event Subscription Implementation

Observer pattern is one of the most useful behavioral patterns. It establishes one-to-many dependency between objects: when one object changes state, all dependents are notified automatically.

Here’s how to implement it properly in Go with real-world examples.

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.

Redis as Message Broker: When It's Better Than RabbitMQ

Redis is often perceived only as a cache. But Redis is a full-fledged message broker that in some scenarios works better than RabbitMQ, Kafka, and other specialized solutions.

Let’s figure out when Redis is the right choice, and when it’s better to take something else.
