Typing a command in the Linux terminal is one of the exciting things. We are like a king who is giving orders to his soldiers to do certain things.

As an update to the situation around Canonical planning to drop 32bit support (and Valve saying bye-bye to Ubuntu 19.10+ support), apparently they're not. Instead, the 32bit libraries will be frozen. Are you confused yet? I sure am.

There will be no 32-bit support at all in Ubuntu 19.10. This is problematic for developers of Wine and Steam and gaming on Ubuntu might be in trouble.

Welcome to Arguments chapter of BASH scripting series. This chapter will introduce you to another new method of getting user inputs for your script. In the previous chapter, we’ve used the read command to get user inputs. The read command works after our bash program is invoked by our bash interpreter ie., user input is prompted after the program is run, but this time we are interested in getting inputs as parameters or arguments so it will later be processed by our program.

rga (or ripgrep-all) is a command line tool to recursively search all files in a directory for a regex pattern, that runs on Linux, macOS and Windows. It's a wrapper for ripgrep, the line-oriented recursive search program, on top of which it enables search in a multitude of file types like PDF, DOCX, ODT, EPUB, SQLite databases, movies subtitles embedded in MKV or MP4 files, archives like ZIP or GZ, and more.

One of the downsides of dropping 32 bit support.

Things are starting to get messy, after Canonical announced the end of 32bit support from Ubuntu 19.10 onwards, Valve have now responded.

I wrote recently that "GogglesMM has been one of my favorite players for quite some time now." So, when I was thinking about interviewing developers who build and maintain open source music players, Sander Jansen came quickly to mind. read more

The Red Hat Enterprise Linux and CentOS Linux operating systems have received new Linux kernel security updates that are marked as important and address the recently disclosed TCP vulnerabilities affecting all GNU/Linux distributions.

Microsoft tactics for defection and takeover of the competition (without coming across as hostile) aren't new tactics; internal documents from Microsoft explain how to achieve this

This tutorial explains how to show all databases in a MySQL or MariaDB server through the command line.

Containers have shifted the way we think about virtualization. You may remember the days (or you may still be living them) when a virtual machine was the full stack, from virtualized BIOS, operating system, and kernel up to each virtualized network interface controller (NIC). You logged into the virtual box just as you would your own workstation. It was a very direct and simple analogy. read more

In general, people are using the proprietary TeamViewer program to do that. But there are many other open source alternatives to TeamViewer that you can use. Here are 5 of them.

Canonical released another update for the intel-microcode firmware for all supported Ubuntu Linux operating systems to address recent Intel MDS (Microarchitectural Data Sampling) security vulnerabilities.

Public Key Infrastructure (PKI) provides a framework of encryption and data communications standards used to secure communications over public networks. At the heart of PKI is a trust built among clients, servers and certificate authorities (CAs). This trust is established and propagated through the generation, exchange and verification of certificates. This article focuses on understanding the certificates used to establish trust between clients and servers. These certificates are the most visible part of the PKI (especially when things break!), so understanding them will help to make sense of—and correct—many common errors.

The Linux Foundation is boosting the Microsoft boosters (as above) and calls that “community”

The makers of the Zorin OS Linux operating system announced today that they partnered with a computer manufacturer to offer users notebooks powered by Zorin OS.

Sysadmins, site reliability engineers (SREs), and cloud operators all too often struggle to feel confident in their infrastructure as it scales up. Also too often, they think the only way to solve their challenges is to write a tool for in-house use. Fortunately, there are options. There are many open source tools available to test an infrastructure's performance. Here are my favorites.

Canonical released a new Linux kernel live patch for the Ubuntu 18.04 LTS (Bionic Beaver) and Ubuntu 16.04 LTS (Xenial Xerus) operating system series to address the recently disclosed TCP Denial of Service (DoS) vulnerabilities.
