This tutorial provides a general description of updating Linux-based firmware and illustrates it with some specific implementations. First, consider the sections of the memory system (Figure 1) and parts of memory that should be updated while transferring software to a new version.

When you think about it, it's surprising how many programming tasks don't require the use of floating point numbers. If you're an embedded systems programmer, you'd probably get fired for using "double" in a C program. If you write PHP or JavaScript, quick, do they even support floating point? One language that doesn't support it is Bash, but let's not let that stop us...

I have spent the first three parts of this series describing the evolution and current state of Flash storage. I also described how to configure an NVMe over Fabric (NVMeoF) storage network to export NVMe volumes across RDMA over Converged Ethernet (RoCE) and again over native TCP.

If you can remember all of your passwords, they're not good passwords. I used to teach people how to create "good" passwords. Those passwords needed to be lengthy, hard to guess and easy to remember. There were lots of tricks to make your passwords better, and for years, that was enough. That's not enough anymore.

Create handy command-line utilities in Rust. This article is about text processing in Rust, but it also contains a quick introduction to pattern matching, which can be very handy when working with text. Strings are a huge subject in Rust, which can be easily realized by the fact that Rust has two data types for representing strings as well as support for macros for formatting strings. However, all of this also proves how powerful Rust is in string and text processing.

How to get started with this useful new programming language.

In a previous article, I discussed Apache Tomcat, which is the ideal way to run Java applications from your server. I explained that you can run those apps from Tomcat's default 8080 port, or you can configure Tomcat to use port 80. But, what if you want to run a traditional Web server and host Java apps on port 80? The answer is to run a reverse proxy.

Tighten up your code and identify errors before they occur with mypy. I've been using dynamic languages—Perl, Ruby and Python—for many years. I love the flexibility and expressiveness that such languages provide. For example, I can define a function that sums numbers:

Can "by hackers, for hackers" sell laptops? System76 sold an Oryx Pro to Rob, and he's here to tell you about it. I should start by saying that although I'm definitely no newbie to Linux, I'm new to the world of dedicated Linux laptops. I started with Linux in 1996, when Red Hat 4.0 had just adopted the 2.0 kernel and Debian 1.3 hadn't yet been released. I've run a variety of distros with varying degrees of satisfaction ever since, always looking for the Holy Grail of a desktop UNIX that just plain worked.
