• Syntax podcast episode 623: “Nothing in CSS” errata

  I just listened to the Syntax podcast for the first time because they were discussing topics near and dear to my heart, HTML and CSS. The episode is called “Nothing in CSS - 0 vs 0px, no, none, hidden, initial and unset”, and they’re talking about all the things that can be none or 0 in CSS and HTML.

• Overview of ICU collation settings, part 2

  The best way to find out which types are available and what they do is to look into the source code, which for ICU is the CLDR project. Let’s start with the definition of the keys in CLDR.

• What’s Wrong with IPv4 and Why We Are Moving to IPv6

  For the past 10 years or so, this has been the year that IPv6 will become widespread. It hasn’t happened yet. Consequently, there is little widespread knowledge of what IPv6 is, how to use it, or why it is inevitable.

  We’ve been using IPv4 ever since RFC 791 was published in 1981. At the time, computers were big, expensive, and rare. IPv4 had provision for 4 billion IP addresses, which seemed like an enormous number compared to the number of computers.

• A Beginner’s Guide to Configuring IPv4 and IPv6 Addresses in Linux

  As a systems administrator, you will occasionally be tasked with configuring or setting up the IP addresses of your servers to keep up with changing network requirements.

• OpenBLAS >= 0.3.23-2 update requires manual intervention

  The openblas package prior to version 0.3.23-2 doesn't ship optimized LAPACK routine and CBLAS/LAPACKE interfaces for compatibility.

• Linux Fu: Easy And Easier Virtual Networking

  One of the best things about Linux is that there are always multiple ways to do anything you want to do. However, some ways are easier than others. Take, for example, virtual networking. There are plenty of ways to make a bunch of Internet-connected computers appear to be on a single private network. That’s nothing new, of course. Linux and Unix have robust networking stacks. Since 2018, though, Wireguard has been the go-to solution; it has a modern architecture, secure cryptography, and good performance.
