In this article, we’ll explore the case for not encrypting absolutely everything. We’ll look at the pros and cons of encryption, and discuss when it’s appropriate to use it—and when it’s not....
Introduction Welcome, fellow engineers! In the whirlwind of modern software development, where buzzwords fly faster than you can say “microservices,” it’s easy to get lost in the hype. Today, we’re going to demystify one of those buzzwords that has stood the test of time: Domain-Driven Design (DDD). But don’t worry, we’re not diving into a philosophical treatise; we’re here to give you the 20% that will make 80% of the difference in your projects....
Introduction In the world of DevOps and Site Reliability Engineering (SRE), the terms “Service Level Objectives” (SLOs) and “error budgets” have become increasingly popular. But are they just new management buzzwords, or do they offer real value in ensuring the reliability of our systems? In this article, we’ll dive deep into the concept of SLOs and error budgets, exploring their practical applications, benefits, and potential pitfalls. What are SLOs and Error Budgets?...
Error handling in Go Go’s approach to error handling is often a topic of debate among developers. Some love it, some hate it, but one thing is for sure: it’s unique. In Go, errors are values, and you handle them using the if err != nil pattern. This might seem verbose, but it encourages explicit error checking and handling. The if err != nil pattern Let’s look at a simple example:...
