This week’s episode of Destination Linux, we’re going to be discussing Web 3.0 . . . what is it and should you be excited about it? Then we have Danielle Fore’ from elementary on the show to discuss the latest release.
The Mars Helicopter continues to amaze, aviation nerds get burned, Google lays off loads of open source people, running a Mastodon instance isn’t for everyone, KDE Korner, and more.
Linux users may not have a plethora of fonts, but there are many lovely and usable fonts. Different Linux fonts are supplied with different Linux distros. What you may need is an efficient way to manage your fonts. Step forward a dedicated font manager utility.
Here’s our verdict captured in a LinuxLinks-style chart. We only feature free and open source software in this article.
Python is a popular programming language that is widely used for web development, data analysis, artificial intelligence, and many other applications. It is easy to learn, versatile, and has a large community of developers who contribute to its development.
Python is a high-level programming language that is widely used for web development, data analysis, artificial intelligence, and more.
Creating tables in MySQL is a fundamental task for any database administrator or developer. A table is a collection of related data that is organized in a specific structure, with rows and columns. In this article, we will go over the basics of creating tables in MySQL and provide examples to help you get started.
MySQL is a popular open-source relational database management system that is widely used for web development, data warehousing, and other applications. One of the first things you’ll need to do when working with MySQL is to create a new database.
Connecting to MySQL using the command-line client can seem like a daunting task for those new to the world of databases. But don’t worry, it’s not as difficult as it may seem.
In this article, we will go over five different ways to empty/delete a large file in Linux. You might have a file that’s gigabytes in size that you want to get rid of quickly, or you want to automate emptying a file for each iteration.
With the three options we have presented in this guide, you can quickly get the latest Firefox version on your Linux Mint.
The preinstalled version is not the latest one and with the three options in this guide, you can quickly get the latest Firefox version on your Linux Mint.
This guide covered how to install TeamSpeak on Ubuntu using three ways. In one of the methods, you will soon start enjoying the comfort of TeamSpeak.

How do you find a soft link?
The netstat is one of the most popular utilities to monitor connections over your network.
After having an OpenStack production and home lab for a while, I can definitively say that provisioning a workload and managing it from an Admin and Tenant perspective is important.
Terraform is an open source Infrastructure-as-Code (IaC) software tool used for provisioning networks, servers, cloud platforms, and more. Terraform is a declarative language that can act as a blueprint of the infrastructure you’re working on. You can manage it with Git, and it has a strong GitOps use case.
This article covers the basics of managing an OpenStack cluster using Terraform. I recreate the OpenStack Demo project using Terraform.
GitOps as a workflow is perfect for application delivery, mostly used in Kubernetes environments, but it is also possible to use for infrastructure. In a typical GitOps scenario, you might want to look at solutions like Crossplane as a Kubernetes-native alternative, while most traditional infrastructure are still used with CI/CD pipelines. There are several benefits of creating your deployment platform with Kubernetes as the base, but it also means that more people would have to have that particular skill set. One of the benefits of an Infrastructure-as-Code tool like Terraform is that it is easy to learn, and doesn’t require much specialized knowledge.
When my team was building our platform services, we wanted everyone to be able to contribute. Most, if not all, of our engineers use Terraform on a daily basis. They know how to create Terraform modules that can be used in several scenarios and for several customers. While there are several ways of automating Terraform, we would like to utilize a proper GitOps workflow as much as possible.
Free, open source and full of bugs (the squishable kind) — Unvanquished is a mixture of strategy and an FPS with a new release v0.54 out now. Unvanquished is a fork of Tremulous, for those don’t know it’s similar in style to Natural Selection with aliens versus humans fighting it out with each having a little base to build.
Bugs! Kill ‘em all! Would you like to know more? Valve have a new Steam Deck and Desktop Steam Beta available with a few bugs being stomped. As per usual, there’s some shared between them since they mostly use the same bits of the Steam client now.
Forspoken has been controversial for quite a lot of a reasons but also a title many were looking forward to. The release was a bit rough but the developers are cleaning it up now and it has some Steam Deck fixes.
The work to improve gaming performance on Steam Deck and Linux desktops for AMD GPUs is always ongoing, and it seems we’re set for another nice improvement to how smooth games are.
Colossal Cave, originally released in 1977 from Will Crowther and Don Woods has been revived and reimagined for modern audiences. Another one for a heavy dose of nostalgia perhaps? This new version comes from Sierra On-Line founders Ken and Roberta Williams.
Oh the nostalgia is heavy with this one! Gem Worlds is inspired directly by the likes of Boulder Dash and Supaplex. I didn’t play either, but it’s also very similar to one I did play and LOVED on Amiga called Emerald Mine.
It’s early days for the game yet with it in Early Access but SurrounDead could be a promising one to play online with some friends.
Great news for users of the lightweight Xfce desktop environment as the next major release, Xfce 4.20, which is currently in early development, will finally bring the long-anticipated and highly requested Wayland support.
That’s right, work on Xfce 4.20 kicked off earlier this month with the release of libxfce4windowing, a new dependency for the Xfce desktop environment to provide support for the next-generation Wayland display protocol.
Git support in Kate landed almost 2 years ago but so far it is undocumented. I am writing this article in order to fill this gap and hopefully make more people aware of the git related features that Kate has.
To be able to use git functionality you need to enable at least two plugins
This is a rather small release with only two new features and one small improvement.
The new version of elementary OS 7 “Horus” is now officially available to download. This version was under development for more than a year by the elementary team. Hence you can expect many improvements across the desktops and applications.
Let’s take a look at the key highlights.
See what’s new in elementary OS 7, the latest stable release of this Ubuntu-based Linux distro. From UI changes, to new apps, to powerful new features.
It’s been just over a year since we released elementary OS 6.1 Jólnir which brought new features and fixes based on your feedback, introduced new office productivity features, and expanded compatibility with a wide range of hardware. So far, OS 6.1 has been downloaded from our website over 400,000 times—150,000 times more than 6.0—and as always, that’s not including downloads from third parties or direct downloads via torrent that bypass our download page!
elementary OS 6.1 was an impressive release. It has been more than a year, and finally, the next major upgrade, elementary OS 7 ‘Horus’, landed. The changes may not be considered a massive overhaul, but the development focus was more on refinements, as previously reported.
The elementary OS developers have been hard at work crafting version 7 of their open source operating system. With this new release, they’ve focused on getting users the apps they need, empowering users with new features and settings, and evolving their developer platform.
When you install and boot up elementary OS 7, there are no obvious and major changes to greet you. In fact, the desktop UI looks very much in line with what the team has released in the past… and that’s a good thing, as the elementary OS UI is one of the finest on the market.
Red Hat Inc. today announced a nonexclusive alliance with Oracle Corp. under which Red Hat Enterprise Linux will become a supported operating system on Oracle Cloud Infrastructure. IBM-owned Red Hat said the deal is significant in that 90% of Fortune 500 companies currently use products from at least one of the two companies.
A discussion that began in 2018 about adopting OpenSnitch in Debian repositories will probably find a resolution in Debian 12.
Are the developers of Linux Mint fans of the Spice Girls? That I don’t know. What I do know, however, is Linux Mint 21.2 has been code-named “Victoria.” I’d like to think this version of the operating system is being named after soccer-star David Beckham’s wife Victoria (who once went by the stage name “Posh Spice” as a member of the aforementioned pop singing group), but probably not.
Anyway, besides the codename of “Victoria,” the Linux Mint developers have shared some interesting tidbits about the upcoming Ubuntu-based operating system. Most importantly, it will be released in June 2023. As expected, Linux Mint 21.2 will once again come with your choice of three desktop environments — Cinnamon, Mate, and Xfce. If you opt for the Xfce variant, you will be treated to the cutting-edge version 4.18.
Linux Mint 21.2 will be released at the end of June. It has the codename “Victoria”. New features will be added to the login screen and the Pix photo app.
There are three types of motors that makers typically consider: stepper motors, servo motors, and DC motors (either brushed or brushless). Stepper motors are great when you need high precision and torque, but tend to have jerky movement.
While we adults don’t experience them often, school kids practice fire drills on a regular basis. Those drills are important for safety, but kids don’t take them seriously. At most, they see the drills as a way to get a break from their lessons for a short time.
Love your plants, but also have a life? If you work long hours, travel often or just can’t be tied down to a regular schedule, the Arduino Plant Watering Kit is for you.
DSM (digital spectrum modulation) is a relatively new radio control technology that is ideal for long-range applications. It uses two methods, FHSS (frequency hopping spread spectrum) and DSSS (direct sequence spread spectrum), to transmit data, with the latter being especially resilient to interference and therefore suitable for transmission over long distances.
Biometric identification and authentication is big business. As an example, consider Apple’s Face ID technology, which has made strong smartphone security both user friendly and readily available. But Face ID requires substantial hardware and computational power to work, which makes it ill-suited for applications where cost is a major concern.
Cathy Pedrayes earned a following as TikTok’s “Mom Friend” for her practical safety tips – from how to break a car window in an emergency to what not to post on social media. She’s a TV host and has been featured on Today Parents, The Miami Herald, BuzzFeed News, The Bump and Good Morning America. Her book, “The Mom Friend Guide to Everyday Safety and Security,” was published last year.
The Pocket editorial and product teams have been busy over the past couple of months to continue delivering the great experience Pocket users have come to expect.

OnlyOffice Desktop Editors is an open-source office suite distributed under AGPL v.3 that combines text, spreadsheet and presentation editors allowing to create, view and edit documents stored on your computer. The application does not require constant connection to the Internet and allows you to create, edit, save and export text, spreadsheet and presentation documents.
Here’s our summary of updates, events and activities in the LibreOffice project in the last four weeks….
FOSDEM is one of the largest meetups for free and open source software projects. After two years of online events due to the panic, it’s back in-person, in Brussels on February 4 and 5! And, of course, LibreOffice and The Document Foundation will be there.
For most of the history of computer programming, there’s been a gap between the programmers creating an application’s code and the designers creating an application’s user experience (UX). The two disciplines receive vastly different training, and they use a different set of tools. Programmers use a text editor or an IDE to write code, while designers often draw concepts of widget layout and potential interactions. While some IDEs, like Eclipse and Netbeans, have interface design components, they’re usually focused on widget position and not on widget design. The open source design app Penpot is a collaborative design and prototyping platform. It has a suite of new features that make it easy for designers and developers to work together with familiar workflows. Penpot’s design interface lets developers write code in harmony with the design process like no other tool does. And it’s come a long way since Opensource.com last looked at it. Its latest features don’t just improve your experience with Penpot, they propel the open source Penpot app past similar and proprietary tools.
The federated Mastodon social network has gotten very popular lately. It’s fun to post on social media, but it’s also fun to automate your interactions. There is some documentation of the client-facing API, but it’s a bit light on examples. This article aims to help with that.
You should be fairly confident with Python before trying to follow along with this article. If you’re not comfortable in Python yet, check out Seth Kenlon’s Getting started with Python article and my Program a simple game article.
Writing the same application in multiple languages is a great way to learn new ways to program. Most programming languages have certain things in common, such as:
These concepts are the basis of most programming languages. Once you understand them, you can take the time you need to figure out the rest.
Furthermore, programming languages usually share some similarities. Once you know one programming language, you can learn the basics of another by recognizing its differences.
A good tool for learning a new language is by practicing with a standard program. This allows you to focus on the language, not the program’s logic. I’m doing that in this article series using a “guess the number” program, in which the computer picks a number between 1 and 100 and asks you to guess it. The program loops until you guess the number correctly.
Golang is an open-source programming language developed by Google in 2007. It is a statically typed and compiled language which makes it lightning fast and
You sometimes want to add a string to an existing data structure.

It’s time for the January 2023 Federal Circuit statistics update! As I’ve done for the last few years, below I provide some statistics on what the Federal Circuit has been doing over the past year. These charts draw on the Federal Circuit Dataset Project, an open-access dataset that I maintain that contains information on all Federal Circuit decisions and docketed appeals. While previous versions of the dataset have been limited to merits decisions, this year we began including non-merits terminations as well. Currently, all non-merits terminations from 2022 are included in the dataset. We’ll be working backwards to add terminations from earlier years.
I just rewatched a 2005 documentary about early ANSI/BBS history on YouTube. It mainly shows the eternal battle of ACiD vs. iCE, two dominant ANSI groups.
In the online circles I frequent, I bump into the notion of “solarpunk” primarily in the form of a label applied to things actual people are actually doing, a kind of practice. But it’s “supposed” to be a genre of fiction, and when I first encountered the term, around ten years ago now (and, yes, for the record, when I chose the handle “solderpunk”, I did kind of like that there was a subtle nod to solarpunk in there, even though at the time I wasn’t anywhere near as focused on sustainability stuff as I am now), there didn’t seem to be any notion of it as anything *other* than a genre of fiction. It was a strange kind of “vapourgenre”, I remember discovering it and feeling like it was really strange that there seemed to more words written about what solarpunk was than there were words written in the total sum of actual solarpunk literature, unless you counted stuff which had been retroactively labelled solarpunk, stuff written years before the label existed. I suppose this has probably changed quite a bit in the decade since, I’m vaguely aware that Tomasino has a solarpunk writing prompt podcast, which I ought to check out some time if I can ever overcome my innate aversion to podcasts.
