• Enable .htaccess on Apache 2 Linux Server

  When using the Apache web server, .htaccess files (also called “distributed configuration files”) are used to specify configuration on a per-directory basis, or more generally to modify the behavior of the Apache web server without having to access virtual hosts files directly (this is usually impossible for example, on shared hosts). For these .htaccess files to have any effect, we must first enable the pertinent setting in the Apache configuration.

  In this tutorial, we will see how to enable .htacces on Apache 2 for a Linux system. You will also learn how to disable it, in case you decide to turn the setting off later.

• System Clock vs Hardware Clock on Linux

  The system clock and the hardware clock are used for different purposes on a Linux system. The system clock is maintained by the operating system, and the hardware clock is maintained in BIOS. The hardware clock will continue to keep time when the computer is powered off, thanks to the CMOS battery on the motherboard. The system clock maintains time by querying online time servers whenever the computer is powered on.

  The hardware clock will set the time for the system clock upon installation if there is no internet connection. Apart from this scenario, there is little use for the hardware clock in Linux. Instead, Linux uses systemd to synchronize the system time with online servers or an NTPD server.

  Linux programs and services will rely on the system clock, not the hardware clock. Usually, the hardware clock will get synchronized to the system time whenever the computer is powered off. This way, the hardware time can remain accurate and will not drift off more than a few milliseconds while the computer is off, usually. In this tutorial, you will learn the difference between system clock and hardware clock, and about commands that can be used to view or set the hardware clock and system clock in Linux.

• How to install, generate and list Locale on Linux

  The locale on a Linux system is what determines the type of characters and encoding that appear in your command line terminal. Changing the locale will set various environment variables to different values. The terminal and other applications can then query those variables to figure out what type of characters and settings to show the user.

  In this tutorial, you will see the step by step instructions on how to list all of the available locales on your Linux system, as well as set and generate a new one to use.

• List of exit codes on Linux

  When a script or process exits or is terminated by some other means, it will have an exit code, which gives some indication about how or why the script or process ended. For example, an exit code of 0 means that the process exited without error – in other words, it completed its task and exited as expected. On the other hand, an exit code of 1 means that the process encountered some kind of error upon exiting.

  In addition to those two exit codes, there are a slew of other reserved codes in Bash that have their own meanings. In this tutorial, we will show you a list of exit codes on a Linux system, and explain what each of them mean.

• Change IP address on Ubuntu Server

  You have two options when configuring the IP address on your Ubuntu Server, and that is either a static IP address or DHCP. A static IP address allows you to manually select your IP address by configuring it on the Linux system, whereas DHCP relies on the router or DHCP server to lease you an IP address – either a reserved one or the next available one that is currently free, depending on the setup.

  In addition to the IP address configuration, Linux administrators may also need to set the DNS server and default gateway, or setup a virtual IP address. In this tutorial, you will see how to change to static IP or DHCP, and edit the other aforementioned network settings on Ubuntu Server.

• How to Install Linux Kernel 6.0 on AlmaLinux 9

  As anyone who has used AlmaLinux for any time knows, one of its primary focuses is stability. This can often mean that the distribution is relatively stable but usually has very outdated packages in terms of new features. For example, at the time of this writing, AlmaLinux features kernel 5.14, but some users may require a more recent kernel for better hardware compatibility, among many other things. While this focus on stability is admirable, it can be frustrating for users who need the latest and most significant features that newer kernels often provide. Fortunately, there are a few ways to work around this issue. One option is to use the ELRepo repository, which has an excellent reputation amongst EL9 distributions such as CentOS Stream, Rocky Linux, etc.

  Some of the various changes besides the typical CPU improvements include the following.

  Alacritty terminal is known for its fast speed. It’s written in Rust and uses OpenGL for rendering to be the fastest terminal emulator available. It is the simplest terminal emulator for Linux because the developers want to increase its performance of it. That means you won’t find things like tabs, splits, or GUI config editor. Therefore, this terminal is for those who are Linux using some old system or have limited resources, or looking for a performance-centric Terminal.

  It is not for those who want some fancy Terminal with dozens of features such as Tabby and Terminator instead a simple, minimal one that can use the GPU to enhance the performance. Well, it is a relatively new Terminal as compared to other popular names such as Gnome terminal or XFCE terminal.
