Try this Linux text editor for Emacs fans

Fri, 12/04/2020 - 20:45

GNU Emacs is a very famous editor, but not everyone knows that emacs is a tradition of text editors rather than just one specific application. The term "emacs" is actually a portmanteau of "Editor Macros," and the first one was programmed in 1976 as a set of macros for the TECO editor.

Why I love Emacs

Wed, 12/02/2020 - 16:02

I'm a habitual Emacs user. I didn't choose Emacs as much as it chose me. Back when I was first learning about Unix, I stumbled upon a little-known feature in a strange application called Emacs, which was apparently hidden away on my computer. Legend had it (and was proven true) that if you typed emacs into a terminal, pressed Alt+X, and typed tetris, you could play a falling-blocks game.

In the year since the Raspberry Pi 4 was released, I've seen many tutorials (like this and this) and articles on how well the 4GB model works with container platforms such as Kubernetes (K8s), Lightweight Kubernetes (K3s), and Docker Swarm.

Journal five minutes a day with Jupyter

Mon, 11/30/2020 - 16:00

Some people follow the tradition of creating New Year's resolutions. A year is a long time, though, so I plan with a seasonal theme or trajectory. Each quarter, I sit down and look at the upcoming three-month season and decide what I'll work on during that time.

For my latest theme, I decided I wanted to write a daily journal. I like having clear commitments, so I committed to writing for five minutes each day. I also like having observable commitments, even if it is just for me, so I put my entries in Git.

All of your heroes have failures under their belts—from minor mistakes to major disasters. Nobody knows how to do everything automatically, and the process of learning is usually a messy one.

Comparing the similarities and differences between inner source and open source

Fri, 11/27/2020 - 16:01

Open source software (OSS) has been around since the 1990s and has thrived, quickly growing to become mainstream. It is now more well understood around the world than it has ever been before. Some refer to it as FOSS to highlight the Freedom part of open source (Free and Open Source Software). And in 2014, at OSCON, the term "inner source" was debuted, and people started talking about how to use the principles of open source, but inside of a company. It raised several questions for those unfamiliar with the term, which I hope to answer with this article.
