  • How to Install Glances System Monitor on Linux Mint 20 - LinuxCapable

    Glances System Monitor is free, an open-source command-line tool for process monitoring, system resources such as CPU, Disk I/O, File System, Load Average, Memory, Network Interfaces and processes. Glances are built with Python language. Glances support cross-platform monitoring, which can be used in conjunction with a web-based interface. One of the excellent features Glances supports is the ability to set thresholds in the program. You can set careful, warning, and critical in the configuration file, which will then relay information in colors that can show alerts to systems resources bottlenecks, system resources issues, and much more. Glances, by default, comes with a pre-set list of colors, but you can modify and add additional configs.

  • How To Install OpenLDAP on Ubuntu 20.04 - idroot

    In this tutorial, we will show you how to install OpenLDAP on Ubuntu 20.04 LTS. For those of you who didn’t know, OpenLDAP (lightweight directory access protocol) provides user authentication and enables you to set up user accounts that provide the user access to each computer in your network without having to set up a local user account on each computer. OpenLDAP is the free and open-source implementation of LDAP. 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 the step-by-step installation of the OpenLDAP on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.

  • Add storage with LVM | Opensource.com

    Logical Volume Manager (LVM) allows for a layer of abstraction between the operating system and the hardware. Normally, your OS looks for disks (/dev/sda, /dev/sdb, and so on) and partitions within those disks (/dev/sda1, /dev/sdb1, and so on). In LVM, a virtual layer is created between the operating system and the disks. Instead of one drive holding some number of partitions, LVM creates a unified storage pool (called a Volume Group) that spans any number of physical drives (called Physical Volumes). Using the storage available in a Volume Group, LVM provides what appear to be disks and partitions to your OS. And the operating system is completely unaware that it's being "tricked."

  • How to back up Linux apps and files on your Chromebook - TechRepublic

    If you've made the jump and installed Linux support on your Chromebook, you've probably already started installing apps and working with files and data. That being the case, you might be curious as to how you back up those apps and data. In some cases, you'll be saving data within the Linux filesystem hierarchy (and not on either your local or cloud storage, via Chrome OS. Fortunately, the Chrome OS developers thought of this, so you don't have to bother with locating that data and running commands to back it all up.

Windows 11 will be the new Vista (or Windows 8)

I've been using Windows 10 in production for about two years now - testing it since even before the official release. Early on, my impression was that it was comparable to Windows 7. Okay. Nothing too special, new or revolutionary. Over time, this impression has changed. With subsequent semi-annual releases, I encountered issues I've never had in Windows before, mostly various system errors and bugs that speak of low quality and bad design. Then, Windows 10 would occasionally undo some of my tweaks and options, wasting my time, and forcing me to tighten the screws ever more. All in all, my outlook isn't bright or happy. Bored and exhausted by the nonsense would be the best word. Now, Windows 11 is coming. As I've done many times in the past, I logged into my Insiders account and started testing, to see what awaits me. Right away, I found the experience quite dejecting. My early impression of Windows 11 Dev Build was mediocre at best, and it progressively got worse with each update. Different from Windows 10, though. What happened was, I found myself reliving 2011, when I tested Windows 8 and came to pretty much the same conclusions. To wit, this is what I think will unfold. Read more

Overcoming the Challenges of Embracing Linux: a Different Perspective

After months of working at SUSE, my Jungle Green t-shirt was finally recognized at a store. “SUSE?” the gentleman asked, pointing at the large white letters. “Yes, I work there!” I responded, thrilled that I had the opportunity to engage in our mutual love of the chameleon, Geeko, “But I don’t work on the technology, I’m in Program Management.” “Well, let me ask you this – what is the operating system on your computer at home?” he asked, inquiring to my level of SUSE-ness. “Just the basic… Microsoft,” I responded. He continued, “I have a virtual machine with Slackware 1.0 I’m running, and I’ve been trying to get my hands on something old, openSUSE older than 5.3.” I breathed a sigh of relief when our conversation was cut short and he ran off to help another customer. Slackware? Virtual Machine? All terms I had just enough exposure to know what category they belonged in, yet not enough to carry a conversation. Despite the embarrassment, I knew I wasn’t alone. A 2020 study by the AnitaB.org Institute found that women make up 28.8% of the tech workforce. When considering open source technology, this number further shrinks down to the single digits. Nonetheless, the number of women becoming cloud native practitioners is growing. Recently, Lynne Chamberlain, CEO of SUSE Rancher Government Solutions, and Denise Schannon, Director of Engineering, joined special host Katie Gamanji for a special feature of OCTOpod in which they discussed their contributions to Linux, challenges they have faced and shared inspiring stories on how they’ve overcome those challenges to get to where they are today.
