How to create database in MySQL | FOSS Linux

Before we look at what MySQL is, let us first discuss what a database is and its use. In a modern setting, databases are common, and they are a standard way of storing data/information. For instance, when you upload a photo to your social media account, your photo gallery acts as a database.

Another instance of database use is when you go to websites, for example, online e-commerce shops, to buy an electronic device. The database, in this case, is the shopping cart where the items you are buying are temporarily stored. Therefore, it is evident that a database is a storage mechanism that we all have encountered in our day-to-day lives.

Rsync Show Progress Bar When Copying Files in Linux

Rsync is a powerful utility to backup and synchronizes your files and directories. You can see Rsync mainly used as a backup solution to snapshot your files and directories.

Rsync does an incremental backup, meaning it only captures what is newly modified (created, deleted, updated). There are many backup solutions like Timeshift, which uses rsync in the background to take backups. It is important that you know how to use rsync which will come in handy.

In this article, I will demonstrate different ways of displaying the progress bar while copying files using the rsync command. As always, either the man page or help command comes in handy to see what options are available for rsync.

System Calls in Linux

System calls are a special set of procedures that regular programs (user space processes) can submit to the Linux kernel for working with files, interacting with hardware, accessing internal OS functionality, implement all sorts of communication and process management and basically do anything else that’s sensitive or performance critical enough that OS kernel must enforce strict controls around it.

Regular processes interface with the OS kernel by supplying a system call name and parameters, the kernel then verifies validity of a system call and executes it within kernel space, returning data and execution status back.

Each system call has a unique number and name for identification. There are separate numbers for 32bit and 64bit architectures.

Parse JSON configuration files with Groovy | Opensource.com

For example, LibreOffice Writer gives access to stuff like user data, fonts, language settings, and (much) more through Tools > Options on its menu bar. Some applications (like LibreOffice) provide a point-and-click user interface to manage these settings. Some, like Tracker (the GNOME task that indexes files), use XML files. And some, especially JavaScript-based applications, use JSON, despite the protestations of many (for example, this writer and this other writer).

In this article, I'll sidestep the debate about whether or not to use JSON as a configuration file format and explain how to parse this kind of information using the Groovy programming language. Groovy is based on Java but with a different set of design priorities that make Groovy feel more like Python.
