Katherine Druckman and Doc Searls talk to Linux Journal Editor at Large, Petros Koutoupis, about moving from Mac to Linux.

I wrote recently that "GogglesMM has been one of my favorite players for quite some time now." So, when I was thinking about interviewing developers who build and maintain open source music players, Sander Jansen came quickly to mind. read more

Containers have shifted the way we think about virtualization. You may remember the days (or you may still be living them) when a virtual machine was the full stack, from virtualized BIOS, operating system, and kernel up to each virtualized network interface controller (NIC). You logged into the virtual box just as you would your own workstation. It was a very direct and simple analogy. read more

Public Key Infrastructure (PKI) provides a framework of encryption and data communications standards used to secure communications over public networks. At the heart of PKI is a trust built among clients, servers and certificate authorities (CAs). This trust is established and propagated through the generation, exchange and verification of certificates. This article focuses on understanding the certificates used to establish trust between clients and servers. These certificates are the most visible part of the PKI (especially when things break!), so understanding them will help to make sense of—and correct—many common errors.

Sysadmins, site reliability engineers (SREs), and cloud operators all too often struggle to feel confident in their infrastructure as it scales up. Also too often, they think the only way to solve their challenges is to write a tool for in-house use. Fortunately, there are options. There are many open source tools available to test an infrastructure's performance. Here are my favorites.

This relatively unknown, but useful, sysadmin tool is getting a new chance for glory via The Linux Foundation.

What does it take to make a Linux distribution like Fedora 30? As you might expect, it’s not a simple process. Changes in Fedora 30 Although Fedora 29 released on October 30, 2018, work on Fedora 30 began long before that. The first change proposal was submitted in late August. By my count, contributors made […]

This article demonstrates how to perform basic file and file I/O operations in Rust, and also introduces Rust's ownership concept and the Cargo tool. If you are seeing Rust code for the first time, this article should provide a pretty good idea of how Rust deals with files and file I/O, and if you've used Rust before, you still will appreciate the code examples in this article.

With the months ticking down to IBM's acquisition of Red Hat, the Linux and cloud power, business continues to perform at a high level.

'Why use a copy when the original is free, proven and battle-tested?' Google is planning to reimplement parts of libcurl, a widely used open-source file transfer library, as a wrapper for Chromium's networking API – but curl's lead developer does not welcome the "competition".…

In the world of free software, many people speak English: It is the one language. English helps us cross borders to meet others. However, this language is also a barrier for the majority of people. Some master it while others don't. Complex English terms are, in general, a barrier to the understanding and propagation of knowledge. Whenever you use an uncommon English word, ask yourself about your real mastery of what you are explaining, and the unintentional barriers you build in the process.

WonderCMS is a free and open source flat file CMS, aimed to be extremely small, light and simple. In this tutorial, we will go through the WonderCMS installation and setup on the Debian 9 system by using Nginx as a web server, and optionally you can secure the transport layer by using Acme.sh client and Let's Encrypt certificate authority to add SSL support.
