  • Persistent Live USB vs. Full Linux install on a USB drive | FOSS Linux

    Live USB is a fascinating way of testing out any Linux distro without modifying or making changes to your computer. Unknown to many, there is data persistency mode in the Live session. So you can make some changes and save the file to your Universal Serial Bus (USB) drive. The data will remain still even after powering off the live session.

  • Toggle Light & Dark Mode for Flatpak Apps in Ubuntu 20.04+ / Linux Mint | UbuntuHandbook

    Using Flatpak apps in Linux? You may found that Flatpak app appearance does not change when toggling light & dark mode or switching to another app theme.

    As more and more apps publish Linux packages via Flatpak, I have a few of them installed in my Ubuntu laptop. However, the apps stick to the light theme whenever I switches to dark mode in Appearance settings.

    Since Flatpak runs in sandbox and does not have permission to access the “/usr” directory, it does not use system theme according to the document. So, some popular GTK themes are packaged as Flatpaks. And, it detects the current system app theme and tries to install the Flatpak version of the theme if available during app installation or update.

    I’m working with default Yaru theme in the most time, so it automatically installs Yaru theme flatpak package but leaves Yaru Dark not installed. When I switching to Yaru Dark, it can’t find the match theme so falls back to the default Adwaita.

    To connect Linux operating systems such as Rocky Linux, AlmaLinux 8, or CentOS, we can use the open-source implementation of Remote desktop protocol called XRDP. RDP is developed by Microsoft and has been an integral part of Windows operating systems. It allows the users to remotely control and use the GUI desktop systems just like a local one. Although, Windows can be operated over this protocol out of the box, for Linux we need to install some additional packages. Here we learn how to set up a remote desktop connect to Rocky Linux 8.

  • Automatically reassign your default printer - Fedora Magazine

    I run Linux,…or does it run me? Some computing paradigms are so ubiquitous, so ingrained, we rarely stop to think that things could work another way. When such a realization comes, we can exercise our freedom – one of Fedora’s four foundations – to improve the user experience. For that sentiment to be more than cliché, I needed to re-imagine the idea of the default printer and how it gets set. This article presents that implementation.

  • [Older] Permanently add a directory to shell PATH

    When you type a command into a Linux terminal, what’s really happening is that a program is being executed. Normally, to execute a custom program or script, we need to use its full path, such as /path/to/script.sh or just ./script.sh if we’re already in its residing directory. Alternatively, we can execute a lot of commands without specifying paths, like uptime or date, etc.

  • 15 Super Useful Examples of Find Command in Linux

    The find command is used for searching for files and directories in the Linux command line.

    Find is one of the most powerful and frequently used commands. It is also one of the most extensive commands with over 50 options and this makes it a bit confusing, specially when it is paired with the exec or xargs command.

    It is impossible for a sysadmin or software developer to avoid the find command while working in the command line. Instead of being afraid of it, you should embrace its power.

    I am going to discuss some of the most common examples of the find command that you are likely to use. But before that, let me show you its syntax and how to use it.

  • Sending logs to Panther using syslog-ng - Blog - syslog-ng Community - syslog-ng Community

    Panther is an open-source log management system, which is also available as a service for a time-limited trial. It is still in beta phase, but it looks promising. You can see the “beta” sign on its opening page: https://app.panther.support/ I tested the time-limited cloud service version, but you can also install it locally, either from Dockerhub, or you can build the containers locally from the source.

    Even if it is still in beta phase, Panther comes with detailed documentation. There is a notable exception: while syslog-ng is shown on some of the figures, documenting it is still to be done. This blog helps you to get started with sending logs to Panther, using syslog-ng. You can use either legacy syslog with TLS encryption (still a bit problematic) or the http() destination to send logs to the Panther HTTP API.

  • How To Install NVIDIA Drivers on Fedora – TecAdmin

    Fedora, the operating system of RHEL(Red Hat Enterprise Linux) does not have pre-installed exclusive Nvidia drivers in it for the users. Although it does have default Nouveau drivers which work in most conditions, you may face some problems while using them. If you encounter issues while using the Nouveau drivers you will have to install the official proprietary Nvidia drivers.

    The official Nvidia drivers can help you get the most out of your GPU by enhancing its performance. In this article, we will learn to install the official Nvidia drivers on Fedora

    However, before we start with the installation process, we need to do system configuration. The first configuration we need to do is stop the GUI from running and the second step is to disable the default nouveau drivers. From the GRUB boot menu, it is really easy and doable.

  • Install Docker and Portainer - blackMORE Ops

    Docker is a set of platform as a service (PaaS) products that use OS-level virtualization to deliver software in packages called containers. Containers are isolated from one another and bundle their own software, libraries and configuration files; they can communicate with each other through well-defined channels. Because all of the containers share the services of a single operating system kernel, they use fewer resources than virtual machines. The service has both free and premium tiers. The software that hosts the containers is called Docker Engine.

    Portainer CE is a lightweight ‘universal’ management GUI that can be used to easily manage Docker, Swarm, Kubernetes and ACI environments. It is designed to be as simple to deploy as it is to use. Portainer consists of a single container that can run on any cluster. It can be deployed as a Linux container or a Windows native container. Portainer allows you to manage all your orchestrator resources (containers, images, volumes, networks and more) through a super-simple graphical interface. A fully supported version of Portainer is available for business use.

  • DearPyGui 1.0.0 user interface Toolkit Released - itsfoss.net

    Published edition Dear PyGui 1.0.0 (the DPG), a cross-platform toolkit for GUI development in Python. The most important feature of the project is the use of multithreading and outsourcing of operations to the GPU to speed up rendering. The key goal of shaping the 1.0.0 release is to stabilize the API. Compatibility-breaking changes will now be proposed in a separate “experimental” module. To ensure high performance, the bulk of the DearPyGui code is written in C ++ using the Dear ImGui library , designed for creating graphical applications in C ++ and offering a fundamentally different operating model. The Dear PyGui source code is licensed under the MIT license. Declared support for Linux, Windows 10 and macOS platforms.

  • Software testing - a 32-year-old message

    And then, after having tested hundreds of Linux distributions, thousands of applications, every release of Windows since 3.11, and then some, I can definitely say that the slow, steady erosion of professional testing in the software world is noticeable. And by that mean, in those scenarios it actually existed, because in some domains, it's never been there, and it shows. If anything, the longer I keep my hands on this or that application or program, the more I'm convinced that the new, casual approach to quality is simply not working. There will be a moment of reckoning.

  • ODROID-H2+ SBC discontinued due to supply shortage - CNX Software

    Hardkernel has just discontinued ODROID-H2+ single board computer based on the Intel Celeron J4115 Gemini Lake Refresh processor, which followed ODROID-H2 SBC itself being discontinued shortly after Intel decided to phase out Intel J4105 and other Gemini Lake processors. The reason given is the “uncertain situation of main component supply”, which could mean Celeron J4115 processor is hard to get (or expensive), or the Realtek RTL8125B chipset provides 2.5GbE networking. That means Hardkernel does not offer any x86 SBC at this time. That’s a shame before ODROID-H2+ was a well-supported SBC running Linux or Windows, and great value for money at $119, especially for people interested in the two 2.5 Gbps Ethernet ports found on the board (and upgradeable to six), not to mention support for SO-DIMM memory and M.2 NVMe SSD.

  • Debian blocks VPN and Tor users from reading its Wiki. – BaronHK's Rants

    I understand that they don’t want VPN and Tor users messing up their Wiki anonymously, where it would be difficult to ban any one vandal, but to block people from even _reading it_ unless they unmask themselves is a bit heavy-handed. On Wikipedia, they block Tor and VPN users from editing, but you can read it all you want, and you can view the page’s source code if you are on a VPN. This is the right thing to do. I’m not sure why Debian is requiring us to de-anonymize ourselves just to read their Wiki. I wish that they would stop doing this.

  • October 2021 Web Server Survey [Ed: Microsoft became so irrelevant in Web servers that it is not even mentioned anymore and most tables don't even list Microsoft (it's miniscule, outside view)]

    In the October 2021 survey we received responses from 1,179,448,021 sites across 265,426,928 unique domains and 11,388,826 web-facing computers. This reflects a loss of 8.59 million sites, but a gain of 1.07 million domains and 20,800 computers. The number of unique domains powered by the nginx web server grew by 789,000 this month, which has increased its total to 79.5 million domains and its leading market share to 29.9%. Conversely, Apache lost 753,000 domains and saw its second-place share fall to 24.7%. Meanwhile, Cloudflare gained 746,000 domains – almost as many as nginx – but it stays in fourth place with an 8.15% share while OpenResty's shrank slightly to 14.5%. Cloudflare also made strong progress amongst the top million websites, where it increased its share by 0.24 percentage points to 18.2%. nginx is in second place with a 22.5% (+0.12pp) share but has closed the gap on Apache which still leads with 24.0% after losing 0.21pp. Apache also continues to lead in terms of active sites, where it has a total of 48.0 million. However, it was the only major vendor to suffer a drop in this metric, with a loss of 277,000 active sites reducing its share down to 23.9% (-0.29pp). In terms of all sites, nginx lost the most (-9.99 million) but remains far in the lead with a total of 412 million.

  • Security Risks of Client-Side Scanning

    Even before Apple made their announcement, law enforcement shifted their battle for back doors to client-side scanning. The idea is that they wouldn’t touch the cryptography, but instead eavesdrop on communications and systems before encryption or after decryption. It’s not a cryptographic back door, but it still a back door — and brings with it all the insecurities of a back door. I’m part of a group of cryptographers that has just published a paper discussing the security risks of such a system. (It’s substantially the same group that wrote a similar paper about key escrow in 1997, and other “exceptional access” proposals in 2015. We seem to have to do this every decade or so.) In our paper, we examine both the efficacy of such a system and its potential security failures, and conclude that it’s a really bad idea.
