Some time ago, I decided to move my computing environment from a Mac Mini PowerPC to a Raspberry Pi Model 2. This article describes my reasons for doing so and how I did it. While it is quite technical in places, if you're considering switching from an existing system to something decidedly lean and mean, there are things that you need to know before making that leap. There are lots of links to click as well, which will lead you to the software and apps that I mention.

In my earlier article, I explained how I transformed a Raspberry Pi Zero into a minimal, portable, go-anywhere computer system that, although small, can actually achieve useful things. I've since made iterations that have proved interesting and made the little Pi even more useful. Read on to learn what I've done.

In a previous article, we deployed a couple of simple websites on our k3s cluster. There were non-encrypted sites. Now that's fine, and they work, but non-encrypted is very last century! These days most websites are encrypted. In this article, we are going to install cert-manager and use it to deploy TLS encrypted sites on our cluster. How to encrypt your website with k3s and Letsencrypt on a Raspberry Pi.

iWave has updated its Linux-driven, i.MX ULL-based “OBD II” telematics and fleet management computer with CAN-FD support. The compact OBD II supports up to 3x CAN and CAN FD connections simultaneously along with OBD-II and SAE J1939 protocols. CAN and the newer, faster CAN FD interfaces are increasingly common on in-vehicle computers. Now, iWave has […]

Rust and dual-partition sets for security, efficiency, and automated updates. Amazon Web Services has begun previewing Bottlerocket, a new open-source Linux distribution designed for running containers.…

Two-factor authentication, or multi-factor authentication, is not a topic only for nerds anymore. Many services on the internet provide it, and many end-users demand it. While the average end-user might only realize that his preferred web site either offers MFA or it does not, there is more to it behind the scene. The two-factor market is changing, and changing rapidly. New authentication methods arise, classical vendors are merging, and products have disappeared.

For some time now, I've been a huge fan of the Raspberry Pi computer in all of its various forms. I have a number of them, and each has a server role to play. Most of the time, they work extremely well, and I'm safe in the knowledge that the small amount of power they consume is keeping the bills down. You don't have to invest large amounts of money to build a relatively powerful system that can be taken on the road and used productively.

Python is a powerful and popular programming language with many packages that are useful for general programming, data science, and many other things. These packages are not included with the Python installation, so you have to download, install, and manage them separately. All of these packages (libraries and frameworks) are stored in a central repository called the Python Package Index, or PyPI for short. This is where pip (short for Preferred Installer Program), Python's package manager, comes into the picture. read more

There are a few Linux commands you should be familiar with in order to manage account passwords effectively. In this article, we'll cover some of the handiest password management commands.

The first personal computer I purchased with my own money was a Packard Bell, back in the mid-1990s. What I remember about that computer was that for US$ 1,500, I had an Intel Pentium processor with a few megabytes of RAM, a modem to connect to my dial-up internet, and no other devices for internet connectivity. read more

In this article, we will deploy a couple of simple websites and learn how to ingress traffic from the outside world into our cluster using Traefik. After that, we will learn how to remove Kubernetes resources as well. Let’s get started!

Unfortunately, good code won't speak for itself. Even the most elegantly designed and well-written codebase that solves the most pressing problem in the world won't just get adopted on its own. You, the open source creator, need to speak for your code and breathe life into your creation. That's where technical writing and documentation come in.

You can safely assume if you were planning on going to a Linux or open-source conference anytime soon, it's been canceled or made virtual. The post Linux and open-source conferences: List of what’s canceled or going virtual appeared first on Linux.com.
