Never stop learning, because life never stops teaching

Interviews these days...

Interviews are the dreaded part of the job search process. They can be nerve-wracking, stressful, and sometimes downright bizarre. Only software engineers will understand what I am talking about. What if I could show how conversations on interviews feel to non-software engineers?

Declarative Kubernetes

Imperative approach using kubectl .... is great, but we came at some point to situation where our commands became too long with many parameters or that running the same command again and again was time-consuming and more error-prone. That is where we stop using imperative approach and start to use declarative approach with Kubernetes Resource definition files.

Kubernetes basics

Kubernetes is more flexible and extensible tool, provides more mature features, like self-healing, rollouts and rollbacks, secret management, auto-scaling and I mean really large scale applications, adoption by big companies like Google, Microsoft, Amazon, IBM, etc. and can run in single cloud, multi-cloud, on-premises, hybrid cloud, etc. This might take longer to learn, but at the end it is worth it. So buckle up and let’s dive into the Kubernetes basics.

Docker Volumes

I am using docker in personal and professional projects for a couple of years now. Like everybody else, I learned it as I went along and learned as little as I needed to know to be able to deliver what I wanted. I never had a chance to sit down and look deeper into it (as no one does these days). But from time to time, I like to dive deeper to figure out more about handling data with docker. And then I thought to myself that what I summarized for myself mighty actually be helpful for someone else too. Therefore, if you are interested in knowing more about docker volumes, you are in the right place.

Lifetimes in Rust functions

Lifetimes in Rust are a way for the Rust compiler to ensure that the references are always valid. They prevent dangling references or data races. The compiler is checking the lifetimes at compile time. If I am right, Rust is the only language that has this concept. In this post, I will show you how to use lifetimes in functions, what doesn’t work, what not to do and what are the best practices.
