Never stop learning, because life never stops teaching

Docker Volumes

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.

Update Python on Ubuntu 22.04

Ok, so you have a fresh installation of Ubuntu 22.04 (Jammy Jellyfish), and you would like to update the default Python 3.10 that comes preinstalled in Ubuntu 22.04 to the latest version. It seems trivial, as you think that you can just uninstall the old version and install the new one. But it is not that simple. The problem is that Ubuntu 22.04 uses python 3.10 for some of its internal tools, and if you uninstall it, you will break your system.

Using GPG key for Git commits on Linux

Introduction “Hey, Stefan, can you please push your changes to the Git repository?” - asked my colleague. “and make sure you sign your commits with GPG!” - he added. “Sure, I will do that!” - I replied. But wait a minute, what is GPG signing? And why should I use it? PGP (Pretty Good Privacy) was initially developed by Phil Zimmermann in 1991 as a commercial product and was designed as a way to encrypt and decrypt email messages.

Symlinks in Unix

Create a link in Unix A symbolic link is a special form of a file. Actually it is not a file just a pointer to a file. This link points to another file somewhere in the file system. You can create link to files and folders. By the look, feel and functionality it is same as Windows shortcut or alias on iOS systems. If the content of the original file changes, so does the content of symlink.

Install NVM (Node Version Manager) for Node.js on Ubuntu 18.04

Managing Node.js version through NVM Node.js is javascript runtime. I am not going to explain why and how it can be used, you can check yourself on node.js website. But the fact is that Node.js comes in different versions and if you used it in the past, you might be familiar that sometimes you just need other version, sometimes newer version, other times older version. There is a easy way to manage those versions with a single command and that’s what I want to introduce you to today.
