Grep Sed AWK Filters

I usually work with *nix systems, and I process text all the time. This consists of CLI tool output, config file modifications and log files scanning. These utilities make it easy to search and manipulate plaintext data. I think they’re an essential part of any developer’s toolbox. ...

Node/Python Version Management

I work with some projects that can be only used with specific versions of node/python and it’s not feasible to simply dockerize them. Every time I switch between these projects I’d need to reinstall different versions of node/python. That would be plain silly… BUT there’s a better way. ...

Reveal.js CLI

Ever since I wrote about VSCode Reveal, I wanted to have a command-line interface to generate the same output. I loved that well-configured behavior and did not want to start from scratch. Finally, I had the time to do it. ...

Storybook

When I develop new web components I find it frustrating that I have to run the app, click it through until the point I find my new visual, just to see how it behaves in a real life situation. Unit tests are great to check whether my component does what I intended, but styling is a whole different story. I’ve been looking for a component preview library for React, that is not invasive and I do not need to change my code with extra markup to make it work, Storybook does exactly what I was looking for. ...

Supercharge your command line

The commmand line can be your best friend during development, if you take some time to get to know its capabilities. But even if you know what it can help you with, you can still extend it. I’d like to introduce you some of my favourite tools, fzf, and oh-my-zsh. By the end of this post I hope you’ll see how well they can work together with you. ...

Developer font

ELK adventures

I have an application that logs a lot, and during development I got tired of looking through the command line for the error logs, that were hidden by other logs (that were also necessary). So I looked around what is the preferred way of handling logs nowadays. ...

Groom merge request

Imagine you want to submit a huge merge request (gitlab terminology), that has many changes from a bunch of commits. You realize that you don’t want to see some changes, but these changes are not in separate commits, so they can’t be easily reverted. There are a lot of small changes. You don’t want to type their reverse, or copy-paste for minutes. You want to keep the commits, not squash them together in the end. What would you do? ...
