  • GNU Inetutils 2.0 Is Released - LinuxReviews

    The GNU Project is "pleased" to announce Inetutils 2.0. This is the first release of the GNU implementations of many commonly used Internet utilities such as ping, ftp, hostname, ifconfig and telnet in six years.

    [...]

    The GNU inetutils contain implementations of a lot of the common network-related utilities found on modern GNU/Linux distributions. Some of the same programs it provides are implemented by the completely different net-tools package and some are implemented by the also very different iputils package. The ping, hostname and ifconfig implementations your favorite GNU/Linux distribution may or may not be provided by GNU inetutils.

    The previous version of GNU inetutils was released on June 10th, 2015. The first version mentioned in the changelog of inetutils-1.3a (the oldest version available for download at the GNU Project), which doesn't have a number, was released on December 30, 1995. A common/version.c was added the following year.

  • libredwg-0.12.3 released

    Add llvmfuzz and oss-fuzz integration, fixed many minor fuzzing errors. libfuzzer is much better than afl++ and honggfuzz.

  • Tips for writing portable assembler with GNU Assembler (GAS)

    Writing assembly code is straightforward when you are familiar with the targeted architecture’s instruction set, but what if you need to write the code for more than one architecture? For example, you might want to test whether a particular assembler feature is available, or generate an object file for use with another tool. Writing assembly source code that can work on multiple architectures is not so simple.

    This article describes common types of problems encountered when working with assembly code, and the techniques to overcome them. You will learn how to address problems with comments, data, symbols, instructions, and sections in assembly code. To get you started, the Portable assembler demo source file provides many examples of GNU Assembler (GAS) assembly code. I’ll use a few of the examples in this article.

    [...]

    This article addressed common problems writing portable assembly code and provided solutions and examples. In summary, writing portable assembler is hard to do and best kept simple, and persistence is the key.

How I digitized my CD collection with open source tools

The restrictions on getting out and about during the pandemic occasionally remind me that time is slipping by—although some days, "slipping" doesn't quite feel like the right word. But it also reminds me there are more than a few tasks around the house that can be great for restoring the sense of accomplishment that so many of us have missed. One such task, in my home anyway, is converting our CD collection to FLAC and storing the files on our music server's hard drive. Considering we don't have a huge collection (at least, by some people's standards), I'm surprised we still have so many CDs awaiting conversion—even excluding all the ones that fail to impress and therefore don't merit the effort.

Hyperbola Linux Review: Systemd-Free Arch With Linux-libre Kernel

In the last month of 2019, the Hyperbola project took a major decision of ditching Linux in favor of OpenBSD. We also had a chat with Hyperbola co-founder Andre Silva, who detailed the reason for dropping Hyperbola OS and starting a new HyperbolaBSD. HyperbolaBSD is still under development and its alpha release will be ready by September 2021 for initial testing. The current Hyperbola GNU/Linux-libre v0.3.1 Milky Way will be supported until the legacy Linux-libre kernel reaches the end of life in 2022. I thought of giving it a try before it goes away and switches to BSD completely. Read more
