Everything* as code

Hello, dear visitor. Seeing you here today means you're likely a developer, engineer, coder, or some combination of these -- and that you're familiar with the term "code". For several decades engineers all over the world were writing code. This code, first and foremost, was meant to solve problems. And today I would like to tell you about solving even more problems with the power of code. I will show you why and how we should use code for more and more scenarios across our professional and personal lives.

A Beginner's Guide to AWS S3 Block Public Access

S3 is an incredibly useful service for storing and sharing a vast variety of files. Due to its ability to store files in a bucket accessible to a broad audience, it is even possible to host a static website. The first "S" in the acronym S3 stands for "Simple." But is it actually so simple when it comes to public access? In this article, I will try to comprehensively figure out the thing that baffles me each time I come across it: the "Block public access" configuration.

Deploying React application with AWS Amplify

AWS has long allowed users to host their static websites using S3 buckets. While this is a very simple and reliable solution, sometimes there is a need for a more complex application. AWS addresses this need with AWS Amplify Gen 2. In this article, I'm going to show you how to create and serve a React application utilizing its power.

Hidden files in an S3 bucket

Recently, during a routine backup procedure for personal files, I discovered that my private bucket, which should contain only one archive, for some reason has approximately 500 objects in it. This surprised me greatly, and I decided to investigate what the issue was and how it happened.

Solving Sad Servers scenarios: part 1

In this series of articles, I will attempt to solve scenarios from the website "Sad Servers" and provide detailed explanations of the tasks and solutions. The website is described as "Like LeetCode for Linux", offering opportunities to train and improve debugging and operating skills with Linux.

Part 1 includes scenarios 1 to 11 (scenario 10 is locked behind a paywall and will be discussed in another article).

AWS open-sourced Secrets Manager Agent: what does that mean?

A few days ago, AWS open-sourced¹ its Secrets Manager Agent, which is designed to help us users fetch secrets more easily and securely. Let's take a look at what it is, compare it with existing solutions, discuss its potential applications and limitations and how it may help us (or not) in our day-to-day operations.

Story time: how I locked myself out of root account and how I fixed it

Yet another reason why I love Linux is the ability to shoot myself in the leg and still be able to do something about it (or not). This approach allows very deep configuration and understanding of the system, but at the same time, it teaches users to be cautious of their actions. Today, I would like to tell a story about how I locked myself out of root access (easy) and fixed it afterward (not easy).

Signing your git commits with GPG key

We all use git. We all are familiar with pull, push and commit commands and we don't give them too much thought apart from that. Like, what can possibly be complicated about a commit? But is it actually this simple and straightforward? Let's find out!

Linux battery management

Yet another reason why I love Linux: everything is a file. Today I would like to talk about the files that help us to understand the health of our accumulator batteries.

Server's first aid kit: a quick way to determine if your server is alive and well

There are a lot of posts in the internet regarding which program or tool does what in Linux systems. Usually it's a brief overview of the program's functionality, a few examples, and that's it. All from the objective point of view: what we want to achieve. But there aren't so many posts discussing the algorithms in which these programs can be used. So I decided to write a quick guide you can follow to determine whether there's a problem with a server and where it is.
