It’s Season 14 Episode 24 of the Ubuntu Podcast! Alan Pope, Mark Johnson and Rhys Davies are connected and speaking to your brain.
A Quick overview of elementary OS 6
One of the most popular pieces of free and open source software is Gimp (GNU Image Manipulation Program). It is the free and open source alternative to things like Adobe Photoshop.
Today we're looking at a bizarre file manager, it's not like this is an amazing tool that everybody should use but fm awk demonstrates how insanely power awk can be if you're insane enough to actually write an entire program in it.
Creating diverse communities requires effort and commitment to creating inclusive and welcoming spaces. Recognizing that communities which adopt inclusive language and actions attract and retain more individuals from diverse backgrounds, the Linux kernel community adopted inclusive language in Linux 5.8 release. Understanding if this sort of change has been effective is a topic of active research. This MC will take a pulse of the Linux kernel community as it turns 30 this year and discuss some next steps. Experts from the DEI research community will share their perspectives, together with the perspectives from the Linux community members. This microconference will build on what was started at the LPC 2020 BoF session on Improving Diversity.
Linux is entering its 3rd decade of existence. And, it will be a glorious celebration around the world in the Web3.0 era. Research revealed Linux systems would soon outpace and outperform many of the existing super-powers of OS industry, including Microsoft. What started out of frustration on working with traditional operating systems (OS) for Linus Torvalds, Linux kernel steadily became a ubiquitous part of the fast-growing open-source DevOps economy. Linux’s popular distribution versions include Fedora and Ubuntu, both of which are now strong components of the internet of things, driving value in the cloud computing setups and robotics. From NASA to Mercedes Benz, there is a streak of Linux visible in the IT and programming world, which needs to be highlighted widely, even as other OS makers shift focus to delivering licensed products that need massive up-hauling every 6 months.
For those that prefer to hold off on upgrading to a new Mesa stable release series until the first point release is out, Mesa 21.2.1 is now available as the first update to this quarter's Mesa 21.2 series.
Mesa 21.2 introduced the Intel "Crocus" Gallium3D driver for i965 through Haswell graphics hardware support, PanVK was merged for starting on Vulkan for Arm Mali GPUs, support for alternate GBM back-ends contributed by NVIDIA, continued work on Intel Gen12/Xe Graphics across the board, various RADV Vulkan driver improvements, and much more. It was quite a busy quarter in the open-source graphics world.
Google Chrome is the most used Internet Explorer software on the earth, with a recent update in 2021 that Chrome is currently the primary browser of more than 2.65 billion internet users as you would know, installing Debian 11, like most Linux distributions, only install Mozilla Firefox. However, installing Google Chrome on Debian is a straightforward task.
If you manage to take a deeper glimpse inside the ecosystem of the Linux operating system environment, you will discover that its built-in commands are sufficient enough to solve most of our computing problems.
One such problem is the need to find and replace text, word, or string in a file especially when you are in a server environment. A solution to this problem lets you handle nagging issues like updating the “/etc/apt/sources.list” file after a successful Linux system upgrade.
The binary compatibility that associates Rocky Linux with RHEL (Red Hat Enterprise Linux) has made this free operating system software a perfect alternative for users that still want to reap the server benefits found in the RHEL ecosystem. It has made Rocky Linux an ideal candidate for server management and networking.
This article seeks to explore how to associate network configurations with IP addresses on the Rocky Linux environment to successfully set up a static IP address.
Piping is a method of taking the output of one command and using it as the input to the second command.
In this tutorial we’ll cover some of the basics of piping in Linux.
Debian 11, codenamed Bullseye, was released on August 14, 2021. This tutorial is going to show you how to upgrade Debian 10 to Debian 11 from the command line. You can follow this tutorial on a Debian 10 desktop, or Debian 10 server. As with every Debian release, Debian 11 will be supported for 5 years. The codename “Bullseye” is named after the toy horse in the Toy Story movie.
Today we are looking at how to install Funkin' vs Bob and Bosip Mod on a Chromebook. Please follow the video/audio guide as a tutorial where we explain the process step by step and use the commands below.
The VLC media player is an open-source, free portable, cross-platform media player software and streaming media server developed by the VideoLAN project. VLC can play nearly all known multimedia files and DVDs, Audio CDs, VCDs, and various streaming protocols and can be extended and customized with various plugins.
By default, Fedora Linux does not include VLC, so users wanting to use the software will need to install it manually. However, this is a straightforward process. In the following tutorial, you will learn how to install VLC Media Player on your Fedora Linux operating system:
In this tutorial, we will show you how to install pgAdmin 4 on AlmaLinux 8. For those of you who didn’t know, pgAdmin is the leading open-source feature-rich PostgreSQL administration and development platform that runs on Linux, Unix, Mac OS X, and Windows. It provides all the features you need to manage your PostgreSQL databases from a web UI. PgAdmin 4 replaces PgAdmin III which was developed in the C++ language and supports PostgreSQL 9.2 and later releases. If you are not a fan of managing databases on the PostgreSQL shell, then PgAdmin4 is the go-to management tool.
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 pgAdmin 4 open source administration and development platform for PostgreSQL on AlmaLinux 8. You can follow the same instructions for Rocky Linux.
Most people think of Linux as an operating system but it is actually a kernel; A kernel is a bridge between the software and hardware of a computer. Linux-based operating systems are actually called Linux distributions which usually include the Linux kernel along with software package managers, software, and graphical user interface.
It is important to always know the kernel and OS version of your system, especially if you’re an administrator. Knowing the version of your kernel and OS can help you determine which package manager to use to install new software and whether that software is supported by your system or not. It can also help in installing security patches and identifying the features available in your system.
The OS version of a Linux distribution can be determined by using the command-line interface as well as a graphical user interface. In Linux, CLI is preferred over GUI as it provides more control over the OS. In this article, we will mostly focus on the command line methods which can be used to check the OS version of a Linux distribution.
There are a number of different methods which can be used to determine the version of a Linux-based OS using the command-line interface.
Fedora Cinnamon is an alternative version of Fedora that uses the Cinnamon Desktop environment from Linux Mint. It is an elegant operating system and very popular with those who like modern features but dislike Gnome Shell. Here’s how to install it on your computer.
KDE’s Kdenlive Video editor 21.08 was released. The official PPA added Ubuntu 21.10 “Impish Indri” support.
Kdenlive, stands for KDE Non-Linear Video Editor, is a free and open-source video editor for KDE though it also works on other desktop environment. And version 21.08 was finally released a few days later than other KDE Gear 21.08 apps.
The new release based on MLT 7 framework which has removed the Automask effect, along with many other legacy and buggy modules. The region module is also removed and replaced with new Effect Masking feature. As well, the old and unmaintained tools like the DVD Wizard and the Preview Compositing mode has been removed.
Uptime-Kuma is an open source monitoring tool like "Uptime Robot" written in Nodejs. It's a self-hosted monitoring tool with a fancy beautiful dashboard and supports multiple notifications methods. The Uptime-Kuma will monitor the uptime of hosts or servers via protocol HTTP(s), TCP, and Ping. If hosts cannot be rach through these protocols in such interval times, the uptime hosts will send notifications via Webhooks, Telegram, Discord, Gotify, Slack, Pushover, Email (SMTP), etc.
In this guide, you will learn how to install Uptime-Kuma on an Ubuntu server and using the Apache web server as a reverse proxy with a free Let's Encrypt SSL Certificate in front of it. During the installation, you will also learn about the nodejs installation through nvm (node version manager).
Although su and sudo both grant administrative privileges, using the latter is advisable. Here's how to disable the root account and use sudo instead.
Depending on how you installed it, your Linux system might be set up to log in to the root account via su instead of sudo. However, you can disable the root account and use sudo instead. Here's how.
ownload Zorin 16 ISO and install it on Virtualbox Virtual machine to experience this latest launched Linux operating system features.
The newly launched Zorin OS 16 is based on Ubuntu 20.04, uses Gnome desktop software and software can be installed from the Ubuntu repository, the snap store, and Flathub. The user can switch between light and dark themes to match the time of day and the pre-installed active wallpaper subtly changes its color tones during the day, similar to what is known from macOS.
With Zorin Connect you can connect Android smartphones to the PC using the appropriate app. You can view cell phone photos on your PC, reply to SMS via the desktop, or exchange files and websites between the devices.
In addition to the paid “Pro” and the free “Core” version, there is also a “lite” version with Xfce as a desktop. With the help of pre-installed Wine, the user can install compatible Windows applications with few clicks.
I practically always write in a positive way (“X is a good practice!”) instead of in a negative way (“Y is a bad practice!”). So why am I writing about confusing patterns instead of writing about positive patterns?
Writing clearly is a LOT of work. A big part of what motivates me to put in the work to write clearly is my frustration with confusing technical explanations (“ugh, everything I read about Linux containers was SO confusing, I wish someone had just told me X Y Z…“).
But, if I’m not careful, it’s easy to reproduce the exact same confusing patterns in my own writing! And the problem with positive patterns (like “avoid introducing unnecessary jargon”) is that they seem so obvious that I trick myself into thinking I’m following them, even when I’m not! So I’m writing these down to try to keep myself honest and hopefully help you avoid some of these patterns as well.
The Web Management for the LinuxSchools project has had two factor authentication for a long time. However this uses client authentication which can be awkward to set up as it involves importing client keys into any devices that you want to access the Web Management from. This may have put users off setting up two factor authentication. An alternative method using one time passwords was seen as a good way to improve on this situation.
While we're busy working on both the upcoming Godot 4.0 and 3.4 releases (with a dev snapshot for 3.4 beta 4 available now), we still cherry-pick important bug fixes to the 3.3 branch regularly for maintenance releases (see our release policy).
Since the release of Godot 3.3.2 in May, there have been a number of bug fixes which are worth including in a new stable release for all Godot users.
Additionally, this release fulfills a new Google Play requirement for Android to target the API level 30 (Android 11). This includes partial support for Android scoped storage, which will be expanded in future releases.
Godot 3.3.3, like all future 3.3.x releases, focuses purely on bug fixes, and aims to preserve compatibility. It is a recommended upgrade for all Godot 3.3 users.
Monster Sanctuary from Moi Rai Games and Team17 grows again, with the 1.2 Legendary Keeper Update out now.
Adding in some more end-game content there's now the Hall of Legendary Keepers to find deep within the Magma Chamber. It presents statues of their biggest Kickstarter backers, who each contributed a team of Monsters that gives players fourteen unique fights - and some of the most challenging in the game. Tough but it has rewards to earn too.
Want to look flashy? There's now player customization too. Different costumes are available, with more to come in future upgrades and you can find them throughout the game or as a reward for "epic accomplishments".
Parkitect, the magnificent theme-park building game from Texel Raptor added online co-op, after being in Beta since April. This follows on from the original multiplayer update that was locked per-platform back in December 2020.
This is great and at times a technical challenge due to the way different platforms handle things, which we've seen before in other games. Crossplay is becoming (thankfully) a much bigger focus in recent years with many more games, and consoles, properly sorting it out so you can play together regardless of your choice platform. For a game like Parkitect, building cooperatively is such a wonderful idea for an already great game.
After having regular early public releases available for around 4 years now MakerKing (previously called Jumpaï), has formally entered Early Access on Steam and it's free to play.
From the various builds we played through, MakerKing has come a very long way and has actually turned into one of the better creator platformers overall. Giving you the ability to create entire levels, play through levels from others and to play online with others too. If you've been looking for something a bit like Mario Maker on PC this is a good choice.
It seems GOG have been watching what Valve are doing with Steam and they've announced the GOG Games Festival.
Today they've announced a bunch of new game releases, more upcoming games, games you can try a demo of and of course there's lots of titles currently on sale. From the press email, GOG mentioned they will be revealing and adding games on a daily basis, so you'll want to check back often to see them all.
As there came out the first beta of Krita 5, I decided to throw it into my KDE/Plasma OBS builds to try it out. To get it working, add my OBS key say in /usr/local/share/keyrings/obs-npreining.asc and add a file /etc/apt/sources.lists.d/obs-npreining-krita-beta.list, containing the following line:
deb [signed-by=/usr/local/share/keyrings/obs-npreining.asc] https://download.opensuse.org/repositories/home:/npreining:/debian-kde:/krita-beta/Debian_Unstable/ ./
While current testing suite of KIO-FUSE tests individual operations pretty aptly, it lacks the support to put KIO-FUSE through regression tests. KIO-FUSE has not been through regression tests and chances are, doing so would uncover bugs that previously went undetected. KIO-FUSE is updated fairly frequently and new features are still being added, making regression testing a necessity to prevent new bugs from creeping in.
The lack of regression tests in KIO-FUSE’s current testing suite can be fixed by integrating XFSTESTS with it. XFSTESTS is considered as the quintessential file system regression testing suite and KIO-FUSE would benefit greatly from it. A more rigorous testing regime would translate to an even more robust and reliable filesystem. Testing KIO-FUSE would mean we’re testing KIO slaves as well. As of now, XFSTESTS doesn’t support FUSE, and that’ll have to be added as a part of this project. FUSE support for XFSTESTS would be a major plus since it’d allow hundreds of file systems written using FUSE to be tested.
Some 18 months of development have gone into crafting the latest stable release of this popular desktop environment.
“The theme for this release has been adding new functionality to the MATE Desktop while maintaining the look and feel that we all know and love,” writes MATE’s Johannes Unruh in the release announcement.
“While all the added features are surely quite exciting we also did not forget to do tons of bugfixing, modernising the code base and optimizing the performance.”
As you may have noticed, there have been various changes in the GNOME developer documentation website, as of late. These changes also affected the API references for GTK and its core dependencies.
What has changed
The main change is that GTK moved to a new documentation tool for its API reference and ancillary documentation, called gi-docgen. Unlike the previous documentation tool, gtk-doc, gi-docgen uses the introspection data that is generated by GObject-based libraries to build the API reference.
As described in a previous post, the goal in this GSoC was to port Icon Library and App Icon Preview to the GTK 4 toolkit, with a corresponding port from libhandy to libadwaita.
In this video, we are looking at Zorin 16 Core. Enjoy!
Today we are looking at Zorin 16 Core. It comes with Linux Kernel 5.11, based on Ubuntu 2004, Gnome 3.36, and uses about 1.8GB of ram when idling. Enjoy!
On August 16, 2021 we released version 8.4 of the EuroLinux operating system. It adds a few important technology highlights. The new release is compatible with the latest version of RHEL. As we already indicated, EuroLinux 8 is a distribution based directly on the Red Hat€® Enterprise Linux€® system source code.
From button-mashing brawlers to massive battle royales, there’s a lot of fun to be had in online gaming. That is, if players’ connections are reliable. If you’ve ever dealt with input delay, or wrestled with lag, you know how important a quality connection is in online gaming. But with edge computing on the horizon, what impact might there be on how we play?
The internet, as we’ve explored in past seasons of Command Line Heroes, is a patchwork of international agreements and varying infrastructure. But there’s something coming to change the ways we connect. In this episode of Compiler, we explore what edge computing could mean for people who enjoy video games, and what this form of entertainment could teach us about the technology.
Red Hat applauds the recent release of Kubernetes hardening guidance from the US National Security Agency (NSA) and the US Cybersecurity and Infrastructure Agency (CISA) to improve the nation’s cybersecurity through their collaborative efforts. Cybersecurity is a team sport and Red Hat is pleased to help foster government and industry collaboration. This guidance will be especially useful to security practitioners in both public and private sectors who can benefit from the experience of leading cybersecurity experts.
As more organizations move to hybrid architectures, operating in one or more clouds as well as on-premises, application development and operations teams have had to adapt. According to our research, 57% of organizations are running their IT infrastructure in heterogeneous environments. Containers – lightweight code/configuration bundles that run without regard to the underlying hardware – have been a key enabler and driver of this transformation. But achieving an efficient outcome from this shift means workloads must be able to run anywhere without being hampered by complex container management issues.
Engineers at IBM Research and Red Hat OpenShift recently joined hands to help researchers tackle two fundamental challenges in today’s constantly changing hybrid cloud field: the first being able to back up their ideas with deep research and the second about assuring the open source community that their idea is important and how it enhances existing software frameworks.
With your fresh Ubuntu 20.04 LTS Focal Fossa installation, especially coming from an entirely different operating system, setting things up to your taste can be a daunting and expensive endeavor.
This tutorial has curated a handful of things to do after installing Ubuntu 20.04 LTS. Canonical officially moved from Unity to GNOME, thus we explain based Gnome Desktop.
With the release of MAAS 3.0, we moved LXD virtual machines out of Beta. Several articles in the MAAS documentation address LXD. Since no document ties all these features together, though, it’s time for a topical blog about LXD.
Skudo is crowdfunding Kryptor FPGA, a single-chip hardware security module (HSM) based on an Intel MAX10 FPGA. At $129 and up, the board embeds a soft-core suite of security encryption functions. A free Raspberry Pi API for Linux is available for the module.
Estonia-based Skudo went live earlier this week on Crowd Supply with its Kryptor FPGA board. The one-chip card functions as a hardware security module (HSM) and a MAX10 FPGA development board. In order to make Kryptor FPGA more accessible to IoT developers and makers, the company says it’s providing a free Raspberry-Pi-compatible API for Linux. Skudo says the API will “allow almost anyone to get started in mere minutes.” An Arduino library is provided also.
Embedded motherboard maker DFI has secured itself a “first.” The company’s new GHF51 board and EC90A-GH fanless PC stand alone as the first to have passed Canonical’s Ubuntu IoT hardware certification process.
The EC90A-GH appears to simply add a heatsink case and port and connectivity options to the GHF51. Both are built around the AMD Ryzen R1000 series, which marks another first as AMD’s only chip for embedded systems that has the ability to multithread. The dual-core Zen chips can be clocked up to 3.5Ghz and also pack three (up to) 1.2Ghz Vega GPUs, support for three external 4K displays and dual 10G gigabit Ethernet.
 Thanks to the good folk who put the hard work into building a UEFI implementation for the Raspberry Pi 4 which "just works", allowing you to install Debian straightforwardly, and especially to Pete Batard who has written up the process and collected a zip file together.
I have an early model Raspberry Pi 4. I wanted to install Debian on an SSD connected via a cable to a USB3 port. It turned out that the version of the software in the EEPROM would not boot reliably so the first task was to update this with the latest stable EEPROM available from the Raspberry Pi downloads.
Lantronix’s Open-Q™ 5165RB SOM is an ultra-compact (29 x 50 mm), production-ready computing module based on the powerful Qualcomm€® QRB5165 System-on-Chip with Ubuntu 18.04 Linux. The Open-Q™ 5165RB utilizes Qualcomm Technologies’ heterogenous compute expertise to provide an SoC with multiple specialized processing cores, including...
Leveraging its involvement in the Ingenuity Mars helicopter, Qualcomm has introduced the Qualcomm Flight RB5 5G platform, a high-end drone reference design with 5G and WIFi 6 connectivity, seven cameras up to 8K resolution, and 15 TOPS of AI performance.
The platform is based on Qualcomm QRB5165 octa-core processor, a variant of Snapdragon 865 for robotics, also found in Qualcomm Robotics RB5 Platform with support for Intel RealSense D435i (that should reach end-of-life soon), and provides an upgrade to the company’s Flight Pro drone based on Qualcomm Snapdragon 820 platform.
Within an industrial setting, being able to determine if and/or when a machine malfunctions is vital to maintaining safety and uptime. This challenge is what prompted a maker who goes by javagoza on element14 to enter into their Design for a Cause 2021 contest with his device, which he calls the VenTTracker.
At its heart, the VenTTracker uses an Arduino Nano 33 IoT mounted onto a small protoboard that is attached to a sliding surface, such as a window or vent. Under normal operation, the device does nothing, but once an anomaly is detected, including an obstacle or breakdown, the onboard OLED screen shows an alert message.
LibreOffice continues to be considered the main alternative to Microsoft Office, and the open-source license makes it one very cost-effective product for both home users and businesses.
But on the other hand, one concern when transitioning from Microsoft Office to LibreOffice is document compatibility and interoperability, something that The Document Foundation has been working around the clock on resolving.
The Document Foundation has announced the latest release of LibreOffice...
Terraform is a powerful tool. However, it has some limitations: since it uses AWS APIs, it doesn’t have a native way to check if an EC2 instance has completed to run cloud-init before marking it as ready. A possible workaround is asking Terraform to SSH on the instance, and wait until it is able to perform a connection before marking the instance as ready.
In this notebook, we will learn about how to use Python sort and sorted methods to sort different types of data structures.
A cryptomining malware that exploits over twenty known vulnerabilities has been dubbed the “King of Vulnerability Exploitation” by cybersecurity experts.
Google has confirmed a whole new bunch of alarmingly serious security vulnerabilities in Chrome 92, just two weeks after the last batch of flaws was fixed. These new security threats mean that "an attacker could exploit to take control of an affected system," the U.S. Cybersecurity and Infrastructure Security Agency (CISA) has stated.
Contribute to Tails by testing our release candidate for Tails 4.22 by the end of August!
The Netfilter project has announced the release of Nftables 1.0.0 for their user-space code for interfacing with the Linux kernel's Nftables subsystem for network filtering and classification.
With Nftables 1.0 there is catch-all set element support, support for defining variables from the command-line, simplified syntax for NAT mappings, and a wide range of other nft command improvements. There are also bug fixes and documentation updates.
A few days ago, the official Odysee company channel made a post promoting a creator channel. The first such promotion, of any channel, in many months. What channel did they choose to promote? One of the hundreds of high quality channels that currently publish to the platform? One of the exciting, popular channels that have joined recently?
No.
The official Odysee company channel made this post, promoting one of the most low quality, vile, vulgar, degenerate channels on the platform. A channel with only a couple dozen subscribers, no less.
That post -- again, posted by Odysee, itself -- contained such text as "You want to F* my TWO HOT GIRLFRIENDS in the A???" and "F*ING breaking my F*ING AHOLE!!"**.
Signing off with the text: "Odysee is his yard now!"
Seriously. Not a joke. Someone at Odysee thought this was a great idea.
It's almost so over the top, it's hard to believe a company (any company) would do such a stupid thing.
[...]
I simply will not associate myself with filth, garbage, degeneracy, and low-quality.
To reiterate: I am not leaving because some degenerate makes vulgar content. I am leaving because the leadership of the company running the platform has made a decision to promote that type of content above all others -- and force creators to associate with it... and end users to see it (with executives screaming obscenities at anyone who disapproves of those actions).
I’m getting ready to teach my Fall 2021 Patent Law class, and that means doing an updated patent grant graph. This year’s version shows U.S. utility patents granted per year from 1840-2020:
The W3C has been working on the "Open Screen Protocol" as part of their Second Screen Working Group. This effort has been about having a web standard so web pages can drive secondary screens to display web content. Unfortunately, the plans are currently being complicated by a number of software patents issued to Apple.
The Open Screen Protocol was published as a working draft earlier this year and is intended to allow web content / web-sites to interact with secondary screens such as for controlling Internet-connected TVs, HDMI dongles, smart speakers, and other secondary Internet-connected devices.
In September 2017, Stefan Makk (the Applicant) obtained an international trade mark registration designating the EU for the word mark “PANTA RHEI”. Registration would be for goods in Class 5 (pharmaceuticals, dietetic food supplements for medicinal purposes, nutritional supplements, non-alcoholic beverages adapted for medical purposes for the prevention and curative treatment of eye diseases, and non-alcoholic dietetic beverages for medical purposes) of the Nice Classification.
In April 2019, Ubati Cosmetics, SL (the Intervener) filed an opposition, pursuant to Article 8(1)(b) of the EU Trade Mark Regulation (EUTMR) based on its earlier word mark “PANTA RHEI”, covering goods and services in Classes 3 (perfumery, essential oils, cosmetics, hair lotion, soap), 35 (‘advertising, business management, business administration, clerical services’) and 44 (‘hygienic and beauty care, and cosmetic treatment’).
In August 2019, the Opposition Division partially upheld the opposition in respect of the goods referred to the above. The Applicant appealed to the EUIPO Fourth Board of Appeal (the board) which subsequently dismissed the appeal.
