Vsftpd is the acronym of Very Secure FTP Daemon: it is one of the most used ftp servers on Linux and other Unix-like operating systems. It is open source and released under the GPL license, and supports virtual users and SSL for data encryption. In this tutorial we will see how to install it and configure it on Linux.

Bloatware is a type of software which is installed by the product vendor (like Samsung) on top of the Android operating system in your mobile phone. The name clarifies; it makes your mobile bloated. Much of the utilities and services installed on your phone are simply not required, and at times may be annoying or consuming a fair bit of battery. Uninstalling a lot of these may buy you an extra day or two of battery power.

Mobile phones have evolved a lot over recent years, and we have seen several mobile-vs-desktop management solutions like Samsung DeX for Samsung Mobile phones, and only available for Windows 7 and 10 as well as Mac. As a non-Samsung or Linux user, one may feel left out. Not so! In fact, a whole lot more power can be provided by the ADB toolset from the Android developer team!

FTP (File Transfer Protocol) needs no presentations: it is among the most used file transfer methods between one or more clients and a server. By design it supports both anonymous access and authentication, but in its most basic form it doesn’t provide data encryption, that’s why it is often secured via TLS.

There are many times when a Bash developer or user will want to run a process in the background, either from the command line or from inside a bash script, and then handle that same process again later. There are various command line tools which allow one to do so. Being able to start, manage and destroy background processes is a requirement for many more advanced level tasks, especially in the areas of advanced scripting and process control.

These days everyone seems to be speaking about Big Data - but what does it really mean? The term is used quite ambiguously in a variety of situations. For the purposes of this article, and the series, we will refer to big data whenever we mean ‘a large amount of textual data, in any format (for example plain ASCII text, XML, HTML, or any other human-readable or semi-human-readable format). Some techniques shown may work well for binary data also, when used with care and knowledge.

BackupPC is a free and versatile backup suite that can run on Linux systems and supports several protocols like NFS, SSH, SMB, and rsync. It can be used to backup numerous Linux, Mac, and Windows machines. It has a lot of nice features like automatic backups and a web interface as its control panel. It also uses file compression and hard links to try and minimize the amount of space that your backups consume. Thus if a file is present on multiple machines, BackupPC is smart enough to only store a single copy of that file in the backup.

If you ever need to record your screen on Ubuntu Linux, there are a lot of tools you can use to accomplish the task. Not all Linux screen recording software is created equal, and you may find that one tool suits your scenario better than others.

If you read our previous linux subshells for beginners with examples article, or are experienced with subshells already, you know that subshells are a powerful way to manipulate Bash commands inline, and in a context sensitive manner.

Bash one-liners can reduce workload, automate something quickly and put the power of ultimate system control in your hands. Over time, you will likely learn to write more complex one-liners and some of the things you end up writing as a seasoned professional will be nearly in-parsible by a beginner. That said, the Bash command and development language is highly structured - and relatively easy to understand - once you know about the in and outs. It really is like becoming proficient in a foreign language.

You may already be versed in debugging Bash scripts (see How to Debug Bash Scripts if you are not familiar with debugging Bash yet), yet how to debug C or C++? Let’s explore. GDB is a long-standing and comprehensive Linux debugging utility, which would take many years to learn if you wanted to know the tool well. However, even for beginners, the tool can be very powerful and useful when it comes to debugging C or C++.

Making use of subshells in Bash provides you with an ability to generate context sensitive information from right within your Bash command. For example, if you want to modify a text string right inside an echo statement, then this can be done easily with subshells.

Redis is open source software used as a database and cache that sits in memory, allowing for exceptional performance. When you're ready to give this lightning fast program a try, the developers recommend installing Redis on a Linux system, and what better candidate than Ubuntu Linux?

If your website is hosted with NGINX and it has SSL enabled, it's best practice to disable HTTP completely and force all incoming traffic over to the HTTPS version of the website. This avoids having duplicate content and ensures that all of the site's users are only browsing the secure version of your website. You should also see an SEO boost, as search engines prefer non-redundant and secured web pages.

Like all Linux distros, it's important to keep your CentOS system up to date in order to make sure that you have the latest security updates and newest features. Updating the system usually involves simply upgrading all installed packages to their latest versions. Every few years, there's a new version of CentOS released, which requires a more involved update process to install.

Compressed files with the .zip extension are commonplace throughout Windows systems, as it's been the native file compression method for the operating system since many years ago. On a Linux system, the nearest equivalent would have to be tar files and various methods of compression like gzip. There are a few reasons why you may need to create or open .zip files on Linux.

The ABS or Arch Build System is a package building system native to the Arch Linux distribution: with it, we can easily build packages which can be installed with pacman, the distribution package manager, starting from source code. All we have to do is to specify instruction inside a PKGBUILD file and then build the package using the makepkg tool. In this tutorial we will see how to customize and re-build an already existing package.

Many developers and programmers choose Manjaro because it's one of the most user-friendly and feature-rich Linux distributions. In this guide, we go over the steps to install the Java Development Kit on Manjaro Linux. We'll show you how to install both the OpenJDK package (which is free and GPL-licensed) as well as Oracle Java SE Development Kit.

Lutris is a game manager that can be run on Manjaro and other Linux distributions, and it does its job incredibly well. It has thousands of games in its catalog and works with very little fuss, allowing you to install games from the cloud and keep them up to date. Most games are "one click install" titles, meaning that you shouldn't have to worry about fiddling with extra configuration to get a Windows game working on Linux. It just works.

A Linux kernel is the core of a Linux distribution and consists of three things: the kernel itself, the kernel's headers, and the kernel's extra modules. The kernel headers are used to define device interfaces. For example, they can be used to compile the module that controls your computer's video card and driver
