How to scan for viruses with ClamAV on Ubuntu 24.04
Author: Bill Toulas • Tags: desktop, security, server, ubuntu • Comments: 22 • Updated: Jun 18, 2024There aren't many viruses made for Linux distributions and as such, most people who use such systems don't even bother using antivirus software. Those however who do want to be able to scan their system or other windows-based systems that are connected on a Linux PC through a network can use ClamAV. ClamAV is an open-source anti-virus engine that is built to detect viruses, trojans, malware, and other threats. It supports multiple file formats (documents, executables, or archives), utilizes multi-thread scanner features and receives updates for its signature database at least 3-4 times a day.

This parameter's default value is “60” and it can take anything from “0” to “100”. The higher the value of the swappiness parameter, the more aggressively your kernel will swap.

Author: Bill Toulas • Tags: arch linux, centos, debian, desktop, fedora, linux, mandriva, suse, ubuntu • Comments: 3 • Updated: Nov 03, 2022This post is a response to the overwhelming comments about Meld (and other tools) on my previous article on text files comparison and merging tools. While my intention wasn't to focus on code text only but to also present something useful to word editors and writers as well, but the coders community objected for the “shallowness” of the previous post so here we go with part 2.

Updated: Oct 28, 2022 For this tutorial, we will use the Whale Docker image. The Whale is the official mascot of Docker and the Whale docker image resembles the cowsay program which generates ASCII pictures of a cow in the terminal with a message. It can also generate pictures using pre-made images of other animals, such as Tux the Penguin, the Linux mascot.

How to Benchmark your GPU on Linux
Author: Bill Toulas • Tags: arch linux, centos, debian, desktop, fedora, suse, ubuntu • Comments: 22Linux is not famous for its gaming abilities and possibilities, and it is only natural that there aren't many GPU benchmarking tools available with which users can test their graphics hardware. There are however some benchmarking suites that can help you determine the various aspects of your GPU performance with precision. In this tutorial I will show you GLX-Gears, GL Mark 2 and the benchmarks from "Unigine Benchmark Products".
