• Essential Guide: How to Install Docker on Ubuntu 20.04 LTS (Beginners Guide)

  Docker is a combo of ‘platform as a service’ products and services which use OS virtualisation to provide software in packages called containers. Containers contain everything an app, tool or service needs to run, including all libraries, dependencies, and configuration files. Containers are also isolated from each other (and the underlying host system), but can communicate through pre-defined channels.

• Demux, mux and cut MP4 in ffmpeg

  Sometimes video and audio needs to be separated into individual files (aka demuxed). This can be handy when some audio artifacts need to be removed (e.g. noise or buzz) from the audio track (aka stream). This can be done easily...

• Oracle Linux 8: Containers made easy with short training videos

  Container technology provides a means for developers and system administrators to build and package applications together with libraries, binaries, and configuration files so they can run independently from the host operating system and kernel version. You can run the same container application, unchanged, on laptops, data center virtual machines, and on a cloud environment.

• Fix for 2createpackages in woofQ

  WoofQ is the build system for EasyOS. It has scripts '0setup', '1download', '2createpackages' and '3buildeasydistro', that are run in that order. The script '2createpackages' splits each input package into _EXE, _DEV, _DOC and _NLS components. Recently, when compiling LibreOffice in EasyOS on the Pi4, the configure step reported that the system boost libraries cannot be used, as some header files were missing. So, I had to use the internal boost, which does make the final LibreOffice PET bigger than it could have been.

• How to Install and Remove Packages in Arch Linux

  Want to install packages on Arch Linux but do not know how? A lot of people face this problem when they first migrate from Debian-based distributions to Arch. However, you can easily manage packages on your Arch-based system using package managers. Pacman is the default package manager that comes pre-installed in every Arch distribution. But still, there's a need for other package managers as Pacman doesn't support packages from the Arch User Repository.

• How to Manage Systemd Services with Systemctl on Linux

  Systemd a standard process for managing start-up services in Linux operating systems. It is used for controlling which programs run when the Linux system boots up. It is a system manager and has become the new standard for Linux operating systems. Systemd allows you to create a custom systemd service to run and manage any process. In this tutorial, we will explain how to manage services with systemd on Linux.

• How to Exclude a Directory While Finding Files in Linux

  In Linux, the find command is used to search for files or folders from the command line. It is a complex command and has a large number of options, arguments, and modes. The most common use of the find command is to search for files using either a regular expression or the complete filename(s) to be searched.

• How to Copy Files with Specific File Extension Recursively

  In Linux, the command ‘cp‘, which standards for ‘Copy‘ is used to copy files and folders to another folder. It is available by default in Linux as part of the GNU Coreutils set of tools. The most basic use of the cp command is to specify the files to be copied as the arguments and to specify the target folder as the last argument.

• How to Copy Large Number of Files in Linux

  We use the cp command in Linux to copy files and directories from one directory to another. It can be simply used to copy a few files or directories, or it can be used with the '-r' argument (which stands for ‘recursive‘) to copy a directory and the whole directory tree structure underneath it.

• What is /dev/null in Linux

  The ‘/dev‘ directory in Linux and Unix based systems contains files corresponding to devices attached to the system. For example, as seen in the screenshot below, the CD drive is accessed using ‘cdrom‘, DVD drive with ‘dvd‘, hard drives are accessed using ‘sda1‘, ‘sda2‘, etc. All these files communicate with the Linux system through the respective files in ‘/dev‘. The input/output processing of the devices takes place through these files. This is due to an important feature of the filesystem in Linux: everything is either a file or a directory.

• What is ‘> /dev/null 2>&1’ in Linux

  /dev/null is a pseudo-device file in Linux, which is used to discard output coming from programs, especially the ones executed on the command line. This file behaves like a sink, i.e. a target file which can be written, however as soon as any stream of data is written to this file, it is immediately deleted. This is useful to get rid of the output that is not required by the user. Programs and processes can generate output logs of huge length, and it gets messy at times to analyze the log.

• Learn the main Linux OS components

  Evolved from Unix, Linux provides users with a low-cost, secure way to manage their data center infrastructure. Due to its open source architecture, Linux can be tricky to learn and requires command-line interface knowledge as well as the expectation of inconsistent documentation. In short, Linux is an OS. But Linux has some features and licensing options that set it apart from Microsoft and Apple OSes. To understand what Linux can do, it helps to understand the different Linux OS components and associated lingo.

• How to Redirect Output to /dev/null in Linux

  In Linux, programs are very commonly accessed using the command line and the output, as such, is displayed on the terminal screen. The output consists of two parts: STDOUT (Standard Output), which contains information logs and success messages, and STDERR (Standard Error), which contains error messages. Many times, the output contains a lot of information that is not relevant, and which unnecessarily utilizes system resources. In the case of complex automation scripts especially, where there are a lot of programs being run one after the other, the displayed log is huge.

• How to Move Large Number of Files in Linux

  To move files from one directory to another, the ‘mv‘ command is used in Linux. This command is available in Linux by default and can be used to move files as well as directories.

Brave Browser Adds Native Support for Decentralized IPFS Protocol

Even though Brave browser was caught up in some controversies last year, it looks like they managed to become the first major web browser to add support for InterPlantetary File System (IPFS) protocol with the help of Protocol Labs. This support was introduced with v1.19.86 release. In case you didn’t know, IPFS is a peer to peer protocol that lets you store and share files. You can safely assume it as something similar to the BitTorrent protocol with some technical differences. Just because it is totally a decentralized system to store and share files, it can be quite effective to fight censorship by big tech and the government.
