• How to Symlink a File in Linux

  A symbolic link, also known as ‘Symlink‘ is a special type of file in Linux, which is used for the purpose of pointing to another file. The symlink does not contain any other data apart from the disk address of the file to which the symlink is pointing to. Symlinks are particularly useful as shortcut files; where you can have the symlink of a program/application on your desktop/home folder, instead of the program file and its dependencies.

• How to Install Wine 5.0 on Debian, Ubuntu and Linux Mint

• How to Change Open File Limit in Linux

  In Linux, there are limits defined by the system for anything that consumes resources. For example, there are limits on how many arguments can be passed to a certain command, how many threads can run at the same time, etc. Similarly, there is a limit on the number of open files. As you might know, an open file is actively being used in some of the other programs and hence consumes memory. You can view and modify the open file limit with the command ‘ulimit‘.

• How to Install GVM Vulnerability Scanner on Ubuntu 20.04

  GVM (Greenbone Vulnerability Management) is an open-source solution for vulnerability scanning and vulnerability management. GVM was previously known as OpenVAS. Greenbone Vulnerability Manager and OpenVAS are widely used by a number of people in the World including security experts and common users alike who used this all in one suite of tools that works together to run the tests against client computers using its own database of known weaknesses and exploits. In this article, we will show How to install and setup GVM on Ubuntu 20.04 to make sure that your servers are protected against attacks.

• How To Install Wine on Debian 10 - idroot

  In this tutorial, we will show you how to install Wine on Debian 10. For those of you who didn’t know, Wine is a free and open-source use that allows users to run Microsoft Windows applications in a Linux environment. In the present day, Wine is a must-have tool to get Linux users who don’t want to be able to let go of Windows native software especially gamers. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step by step installation of Wine on a Debian 10 (Buster).

• How to boot multiple ISO images from one USB drive on Linux

  A bootable USB drive allows you to instantly run a full-fledged OS from the file system on the USB drive, rather than from the host computer's hard drive. Such capability is quite useful in various scenarios, for example, when you need to diagnose and repair a corrupted file system of a host computer, or when you want to test drive an alternative OS or the latest release of your favorite Linux distro before installing it. You can easily create a bootable USB by burning an ISO image on a USB drive with tools like Gparted or UNetbootin. There is nothing fancy. However, for people like me who would like to try out all sorts of Linux distros and different releases of each distro for testing purposes, as part of writing tutorials, what would be nice is the ability to boot multiple ISO images from a single USB drive. However, a typical bootable USB drive or memory stick can only boot from a single ISO file stored on the drive. It is not only inconvenient as I need to re-format the USB drive with a new ISO file every time I need to boot from a different ISO file, but also quite wasteful as a typical USB drive has much bigger space than a single ISO image. Although it's possible to boot ISO files using GRUB, it's rather cumbersome to modify GRUB configuration each time you want to add a new ISO file to try. Also, the GRUB-based approache does not provide the portability of a USB drive.

• How to compress PDF files on Linux | FOSS Linux

  PDFs offer us one of the most convenient ways of sharing images. However, by stuffing tons of data such as images and graphics, the PDF file size can get too big to share via emails. If you are also suffering from this issue, you have come to the right place. Here, we will show you how to compress a PDF file in Linux to reduce its size drastically. And don’t worry, we have included both GUI and Terminal methods in this tutorial.

• How to fix error : Conda command not found

  If you have already installed Miniconda and cannot run the commands in the terminal while using zsh, you may find the following helpful. In case you have already added the appropriate path environment variable to bashrc and bash_profile files, you would need to add the Miniconda folder directory to the PATH environment variable of zsh shell.

• Introduction to ContainerJFR: JDK Flight Recorder for containers

  OpenJDK has long been a top pick for real-world applications and workloads, chosen for its blend of performance, compatibility, reliability, and observability. For many years, JDK Flight Recorder (JFR) and JDK Mission Control (JMC) have contributed to OpenJDK’s success. Until recently, both were commercial features, however, available only for certain users and workloads. In 2018, JDK Mission Control and JDK Flight Recorder were open-sourced. JDK Flight Recorder is now built into the Java Virtual Machine (JVM) for later releases of OpenJDK 8 and all versions from OpenJDK 11 onward. Open-sourcing these tools brings their power—always-on, near-zero overhead production profiling and monitoring, application-specific custom events, and unified-core JDK analytical tooling—to all JDK users. On the downside, JDK Mission Control and JDK Flight Recorder have emerged into a world rapidly moving toward containerization, which is not the paradigm that they were designed for. The desktop-only JDK Mission Control application requires developers and administrators to access flight recordings on the local disk. Otherwise, one resorts to a complex and potentially insecure setup to connect directly to applications over Java Management Extensions (JMX) in the cloud. Similarly, the bare-metal-focused JDK Flight Recorder allows JVMs to dump recordings into the local filesystem, but not when the application runs inside a container. In that case, the filesystem is not easily accessible from the outside world, and it isn’t possible to retrieve and analyze recordings.
