Improved Battery Reporting For Newer Logitech Devices Coming To Linux 5.12

Newer wireless Logitech keyboard/mice supporting "unified battery" reporting will be supported beginning with Linux 5.12 as a newer interface compared to the existing battery reporting support. While Logitech doesn't engage much with seeing good Linux support by their consumer devices (there has been only a handful of commits from Logitech developers over the past decade - in most cases providing just some basic bits), the open-source community through reverse engineering and widespread testing have filled in the voids. Wireless Logitech devices on Linux have generally enjoyed working battery reporting under Linux while now support for an interface found with newer devices is forthcoming.

• UBlock Origin and custom filters - Mini tutorial

  Several months ago, I wrote a review of UBlock Origin. It's a powerful, nerdy browser extension, available across the wider range of browsers out there, with the sacred purpose of making the Internet palatable for intelligent use. It does so by being a sophisticated adblocker and content blocker. Since, I've received requests for additional tutorials - and also found myself tackling a few real-world issues with somewhat overzealous content blocking. For example, on Bing images, if I clicked on an image, they would show up for a second, flicker and then disappear. Not consistently - but always with UBlock Origin active. So I used this opportunity to write a little guide on how to create custom filters. Let's have a look.

• apt-key Is Deprecated. How To Add OpenPGP Repository Signing Keys Without It On Debian, Ubuntu, Linux Mint, Pop!_OS, Etc.

  This article explains how to securely add OpenPGP keys and third-party APT repositories on Debian, Ubuntu, and Linux distributions based on these, like Linux Mint, Pop!_OS, Elementary OS and so on, to replace the deprecated apt-key. When you try to add an APT repository key using apt-key on Debian, Ubuntu and Linux distributions based on these, you'll see the following message: "Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8))". The apt-key man page mentions that the "use of apt-key is deprecated, except for the use of apt-key del in maintainer scripts to remove existing keys from the main keyring". What's more, "apt-key will last be available in Debian 11 and Ubuntu 22.04."

• How to count lines of source code in Linux

  For various reasons you may want to know in how many lines of code given open-source software is implemented. For example, you want to estimate the effort devoted to developing a particular open-source program. Or you want to gauge the size and complexity of a program before trying it. There is some controversy as to using source lines of code (SLOC) as a metric to determine the size of a software program, since existing programming languages differ greatly in terms of clarify and brevity. In any rate, if you would like to count the number of source code lines quickly and accurately, you can use a command-line tool called cloc (short for "Count Lines Of Code"). cloc is a Perl program that is dedicated to counting the number of lines of code. To estimate the size of codebase accurately, cloc automatically detects different types of programming/scripting languages, and discounts comment lines and blank lines based on the type appropriately.

• How to List Directory Contents on Linux - buildVirtual

  When working with the Linux file system, its important to know some of the different ways you can list directory contents on Linux. This article will look at some of the commands you can use to list directory contents, which will work on whichever version of Linux you are using. These commands will also work to list directory contents on VMware ESXi. It will cover how to do a basic directory listing, how to list specific information such as file size and permissions, and how to sort and filter the directory list output. Let’s start by looking at the basic usage of the ls command, before moving onto some more advanced examples of how you can use ls to list directories and their contents.

3 Helpful Networking Projects for Your Raspberry Pi

In spite of being a beloved companion to computer hobbyists the world over, the Raspberry Pi doesn’t get enough credit. In fact, single-board computers of all stripes haven’t gotten their due — I just happen to have a Raspberry Pi. It was upon casting a stray glance into the corner of my room where my Pi is, churning away on the previous task I assigned it, that I pondered all the loftier projects I have in mind for it. It will probably be a while before I tackle those grand designs. But the next best thing to following my dreams is to share them. The ideas here are charcoal sketches, not full illustrations, but they yield a rough picture. I should also note that these projects all contain Linux in their blueprints (shocking, I know). As this is the preliminary stage, we can leave the exact distribution blank for now. You can safely trust, though, that any services we might need our Pi to run will fasten flush onto a Linux base.
