Category: Linux

Linux is my primary operating system. I used it on the servers, desktops, laptops, netbooks, and even mobile phones since approximately 1997. I’ve tried a number of distributions over the years, and even created a couple myself. I still look around sometimes to see what others are up to. But most of my machines are running some sort of Red Hat – either a quick and easy Fedora Linux, or a stable and secure Red Hat Enterprise Server, or a cheaper CentOS alternative.

And while by now I am very comfortable in the Linux environment (both graphical and command line), I still discover a lot of new and interesting things about it. When I come across something worthy, I usually share it with the rest of the Open Software world, using this category.

Managing dotfiles with rcm

These days it is a common practices to manage, version, and share configuration files for command line tools (bash, vim, etc) via a GitHub repository. There are plenty of open repositories to study and borrow things from, as well as the tools and scripts to help one with setting things up. Have a look at the awesome-dotfiles – a curated list of dotfiles resources.

Fedora Magazine runs an article about rcm – one of the many tools that are handy for managing dotfiles.

Personally, I haven’t heard of rcm until now. My own setup went through several iterations, varying from custom scripts, to Puppet, and now to Ansible. Have a look here. By the way, my dotfiles aren’t only about the command line tools. I also keep my desktop environment configuration in there (MATE + i3).

eDEX-UI – a sci-fi terminal

eDEX-UI is a science fiction terminal that runs on most operating systems. It was heavily inspired by the user interfaces in sci-fi movies, like TRON, Minority Report, and others. While it’s not very practical for the day-to-day use for anyone heavily using command line, it’s a lot of fun to run when there are non-technical people around, staring at your screen.

The installation is pretty simple:

git clone https://github.com/GitSquared/edex-ui.git
cd edex-ui
npm run install-linux
npm start

I think it works even better with a large touch screen, but I don’t have one around to try it on.

Awesome Interviews

Awesome Interviews is a curated awesome list of lists of interview questions. Technical interviews, mind you. It covers a wide range of areas from a variety of programming languages, frameworks and databases, to operating systems, data structures and algorithms. There also coding exercises and much more.

This list links to some really great resources for both candidates, who are preparing for the interviews, and interviewers who want to make their interviews better.

SSH Examples, Tips & Tunnels

“SSH Examples, Tips & Tunnels” is a nice collection of tips and examples for Secure Shell (ssh) users. It covers a variety of scenarios from simple remote connections, to file copying, to tunnels and jump hosts.

Programmer Playing Cards

I have recently blogged about the Faces of Open Source project. That’s a great initiative. But here’s another one, with a lot more practical approach – Programmer Playing Cards. It is a deck of playing cards, featuring people who influenced the world of computer programming in a variety of ways. Each card has a photo of a person, his or her name, what was the influence, and, as a nice touch, a quote from that person.

Here’s an example with Larry Wall.

More examples as well as instructions on how to get these cards are here.
