• Davie Street Enterprises: A case study in digital transformation

  We would like to introduce you to Davie Street Enterprises (DSE). DSE is a fictitious 100-year-old multinational corporation that is beginning its digital transformation journey. In this post we will lay the groundwork for a series following DSE as an illustration of how some Red Hat customers are preparing for and succeeding at digital transformation to save money, become more efficient, and compete more effectively. The company isn't real, but its struggle is very real for many organizations. Throughout this series, we will explore the business problems any number of organizations are challenged with and how DSE, with the help of Red Hat and its partners, plan to solve those problems. To start, let’s learn more about DSE, its business, and some of the associates involved in its digital transformation journey.

• Farewell 2020: A year of togetherness with our EMEA partners

  When reflecting on 2020, I do what many people do and think about what things were like prior to this year. For me, I immediately go back to a spring day three years ago. Red Hat was hosting our EMEA Partner Conference; a mix of distributors, independent software vendors (ISVs), system integrators and solution providers from across the region. Alongside the usual product updates and market insight sessions you might expect, we decided to do a little drumming. A lot of drumming, in fact — 900 people banging bongos and clashing cymbals. Other than the noise, what I remember was the genuine sense of togetherness; embarrassment and egos put to the side in the pursuit of the perfect tempo. It seems drumming is a good signal of solidarity. Even in a large group, it’s easy to notice someone beating to a different rhythm. Trainers and coaches use this drumming technique frequently to promote unity and coordination. Our coach that day later congratulated me on "having such a tight knit group of employees." When I told him they weren’t our employees but partners from 550 different companies, he couldn’t believe it.

• Visualizing system performance with RHEL 8 using Performance Co-Pilot (PCP) and Grafana (Part 1)

  When it comes to performance metrics data collection and visualization on Linux, PCP metrics collection and visualization are key. Red Hat Enterprise Linux (RHEL) 8 provides an excellent framework for collecting performance metrics and visualizing them! The days of poring over command line output to try and figure out what is happening on a system are gone. In this series, I’d like to introduce the power of using Performance Co-Pilot (PCP) and Grafana to visualize system performance data in RHEL. By default, Performance Co-Pilot is not installed on RHEL 8. We believe in giving users choices and as such, you have to opt-in to using Performance Co-Pilot.

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.
