We cover events and user groups that are running in France. This article forms part of our Linux Around The World series.
System76 has refreshed its thin-and-light take on Linux laptops, the company announced Tuesday, as spotted by Tom's Hardware. The revamped 14-inch Lemur Pro, like its predecessors, prioritizes a longer battery life, with the latest model claiming up to 14 hours of use.
It's time once again for The Weekender. This is our departure into the world of hedonism, random topic excursions, whimsy and (hopefully) knowledge. Thanks for listening and, if you happen to get a chance, feel free to call us or e-mail and send us some feedback. Tell us how we're doing. We'd love to hear from you.
In this video, I am going to show how to install Ubuntu Unity 22.04
Finally, a decent replacement for Skywave linux! This is a great starting point for hams that want get into linux. One install for a complete desktop system with nearly all of the available ham radio software already installed and ready to run.
The new movement to leave GitHub, an Ubuntu bug biting 22.04 users, the hardware platform Fedora might start taking seriously, and a major desktop dev departs Red Hat.
After almost 9 years since the beginning of the last wxWidgets stable release series, the first release in the new stable 3.2 series is finally available on GitHub. You will find there archives with the library sources and documentation as well as binaries for the selected Windows compilers such as Microsoft Visual C++, MinGW-w64 and TDM-GCC. You can also read the updated documentation for this version and, in particular, if you’re new to wxWidgets, you may find the installation guide a good starting point.
Many other modules might trigger ACPI device registration. This means the the basic ACPI subsystem has to be up and available before much of the Hardware is usable. Hence, we can see that the ACPI subsystem gets registered here. What I am not certain of is when does this code get called?
To back up a bit, I was reading the ACPI Kernel documentation and saw that something needs to scan the ACPI namespace for devices. Yes, I was starting in the middle.
SELinux is a Linux kernel security implementation that allows system administrators to have more control over the system. It was originally developed by the United States National Security Agency (NSA) as a series of patches to the Linux kernel using Linux Security Modules (LSM).
It provides a mechanism for supporting access control security policies, including MAC (mandatory access controls). The main reasons behind the implementation are to enforce data confidentiality and integrity, as well as to protect processes from untrusted inputs.
Recently, I posted a tutorial on deploying SFTPGo. During my work with this platform, I discovered that if you decide to venture beyond the realm of the default virtual folders, things get a bit complicated and you have to not only add users and groups to SFTPGo but also to the Linux system. This doubles the amount of work you have to do, and if you’re dealing with a lot of users, this can get problematic.
I you opt to keep your users within their virtual folders, this isn’t a problem. But for my purposes, I need to be able to share folders outside of /srv/sftpgo.
If you don’t want to have to jump through the same hoops I did, I have a quick fix for you. Let me show you how it’s done.
One of the best features of Fedora Silverblue is that it allows you to safely and easily try and switch between several variants of the distro. Here's how you can use a process known as "rebasing" to explore different versions of this unique Linux distribution.
Although none of the following commands are destructive, it’s always best to back up your data before changing options in your operating system in case something goes wrong.
Amazon RDS provides an enhanced monitoring feature for databases. In this tutorial, you will learn how to use the ‘IAM Passrole’ permission for enabling enhanced monitoring for Amazon RDS. We will see this by demonstrating a simple example.
In this tutorial, we are going to explore how to install Apache Cassandra 4 on our Ubuntu 21.10 server. Apache Cassandra is an open-source, free, NoSQL database used to store large data. Its linear scalability and proven fault tolerance on commodity hardware or cloud infrastructure make it the perfect platform for mission-critical data.
In this tutorial, we will show you how to install Nvidia Drivers on Ubuntu 22.04 LTS. For those of you who didn’t know, Ubuntu by default uses the open-source video driver Nouveau which has limited support and features when compared with proprietary Nvidia drivers. The objective this article is to install the NVIDIA drivers on Ubuntu 22.04 and switch from a default opensource Nouveau driver to the proprietary Nvidia driver. Fyi, Nouveau drivers are slower than Nvidia’s proprietary drivers, lacking the latest graphics card hardware’s latest features, software technology, and support.
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 Nvidia graphics processing units (GPUs) Drivers on Ubuntu 22.04 (Jammy Jellyfish). You can follow the same instructions for Ubuntu 22.04 and any other Debian-based distribution like Linux Mint, Elementary OS, Pop!_OS, and more as well.
In this tutorial, we will show you how to install LAMP Stack on AlmaLinux 9. For those of you who didn’t know, A LAMP stack is a group of open-source software that is typically installed together to enable a server to host dynamic websites and web apps. It comprises the Apache web server, MariaDB database server, and PHP which is a backend scripting language used for developing dynamic web pages.
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 LAMP Stack on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.
Security-Enhanced Linux (SELinux) is a form of mandatory access control (MAC) that helps Linux systems enforce file and process permissions. It's a default subsystem on Red Hat Enterprise Linux (RHEL), CentOS, Fedora, and many other Linux distributions.
To create a directory in Linux, you use the mkdir command. It stands for 'make directory' after all. It's quite a simple command.
PipeWire is a graph-based processing engine, that focuses on handling multimedia data (audio, video and MIDI mainly).
It has gained steam early on by allowing screen sharing on Wayland desktops, which for security reasons, does not allow an application to access any framebuffer that does not concern it. The PipeWire daemon was run with sufficient privileges to access screen data; giving access through a D-Bus service to requesting applications, with file-descriptor passing for the actual video transfer. It was as such bundled in the Fedora distribution, version 27.
This is going to be a very interesting release this month for users. Quite a large number of features landed for this release!
Automatic TSO mode migration
When FEX is running a single threaded application, we can be optimistic and disable heavy TSO-emulation related features. This significantly speeds up some single threaded applications. Once the program creates a thread then FEX will disable this optimize and clear its code cache to be safe.
Over 120 individual programs plus dozens of programmer libraries and feature plugins are released simultaneously as part of KDE Gear.
Today they all get new bugfix source releases with updated translations, including...
A list of ten great KDE apps (Part 2) spread across productivity, utilities and games.
Adwaita stans listen up: that exceptionally sweet theme pack you can use to make Firefox look like GNOME Web has been updated.
And I don’t mean ‘updated’ in the sense it just supports the latest Firefox 102 release – that’s a given. Rather, the Firefox GNOME theme has been updated to follow GTK4/libadwaita styling.
Something I know I’ve been waiting for.
It means you can very easily make the latest version of the Firefox web browser looks über integrated and ingratiated on the GNOME 42 desktop (well, those GNOME 42 desktops where the default Adwaita theme is in use).
The yum and dnf package managers are used to install packages or software on your RedHat-based Linux distributions like Rocky Linux. Moreover, the ‘yum’ command is used to check security updates and binary package information. In this article, we will explore different uses of the yum command in Rocky Linux 8.
Open the terminal and log in as the root user through the terminal.
This report covers work that happened between April 5th and July 4th. For previous work, see the 2022Q1 report.
Over the past decade, powerful AI systems have matched or surpassed human levels of performance in a number of specific tasks such as image and speech recognition, skin cancer classification and breast cancer detection, and highly complex games like Go. These AI breakthroughs have been based on deep learning (DL), a technique loosely based on the network structure of neurons in the human brain that now dominates the field. DL systems acquire knowledge by being trained with millions to billions of texts, images and other data instead of being explicitly programmed.
These task-specific, DL systems have generally relied on supervised learning, a training method where the data must be carefully labelled, - e.g., cat, not-cat, - thus requiring a big investment of time and money to produce a model that’s narrowly focused on a specific task and can’t be easily repurposed. The rising costs for training ever-larger, narrowly focused DL systems have prompted concerns that the technique was running out of steam.
The recent implementation of the CableLabs 10G Lab environment facilitates the service provider's relentless "innovation journey" and surmounts a myriad of technical and logistical challenges while propelling the industry forward. Additionally, it embraces open and co-compatible configurations to provide a successful proof of concept (POC) and vendor collaboration.
In an industry undergoing constant change, Red Hat’s annual community and social responsibility report is an opportunity for reflection. This is particularly true of our 2021 report, which offers a view into how throughout the pandemic (and beyond), we found new ways of collaborating and contributing to the communities around us.
New iso images of Sparky 2022.07 of the (semi-)rolling are ready to go.
Sparky Linux released an update to their rolling edition with updated packages in the Debian and Sparky test repos as of July 5, 2022.
Jack Wallen shows you how easy it is to install a wide-ranging load monitor to Ubuntu Server so you look out for bottlenecks and other issues.
Every Linux system admin knows how important it is to be able to keep track of how a server performs. Whether it’s a load average, kernel usage, filesystem usage or network I/O, you need the tools to keep tabs on that information. Of course, because this is Linux, there are a lot of options, one of which is called Monitorix. This open-source tool is capable of watching the following:
As of Ubuntu 22.04, the Pimoroni Unicorn hats are supported on Ubuntu out of the box. This includes the standard Unicorn Hat, Unicorn pHAT, Unicorn HAT Mini, and Unicorn HAT HD.
The Chromium browser package (Snap version) in Ubuntu Software is missing VAAPI hardware decoding support. Ubuntu developer team is finally working on get the feature back!
As you may know, Ubuntu now includes the chromium web browser in the system repository as Snap package that runs in sandbox. However, the package is missing the graphics hardware acceleration since version 72 which was released a few years ago in 2019.
Some third-party PPAs are being maintained with Chromium packages, either due to lack of hardware acceleration or just because they don’t like Snap.
For Chromium fans who are OK with the Snap package, you can now help testing the new hwacc build that uses the graphics card for video playback.
Ubuntu is arguably the most widely used Linux-based desktop operating system (OS) out there. It is a free, open-source, and easy-to-use Debian Linux derivative first launched in October 2004, by a team of Debian developers set up by Mark Shuttleworth, who together founded Canonical – the publisher of the OS. Canonical now offers professional services at a low cost to fund the improvement of the Ubuntu platform.
Ubuntu desktop powers millions of PCs and laptops around the world. It ships with everything you need to run your organization, school, home, or enterprise, as a result, Ubuntu competes well with any proprietary desktop OS available on the market including Microsoft Windows desktop and Apple macOS.
First released in August of 2006, Linux Mint is another widely-used OS for desktop and laptop computers. It is derived from Debian and Ubuntu and is a highly recommended alternative to the Ubuntu desktop and one of the best alternatives to Windows OS and macOS.
Flutter is an open source UI framework, released in 2017 by Google, that allows the creation of multi-platform applications, without having to worry about constraints related to supported platforms.
Flutter applications are written in a programming language called Dart, then compiled and run as a native applications, to be efficiently executed on Linux, Android, iOS or Windows platforms, but also as Web applications.
Gtranslator is an application which helps translators to do translation of application from one language to another through po files .
Kids are, by default, curious beings. Everything is new to them, and they love to explore. In this era of technology, keeping children up-to-date is also a part of parenting. Introducing them to programming is a great start, and there are tons of programming tools for kids to make it a fun experience.
Studies suggest that the best age to start with programming or coding is around five to seven years, depending on the kid’s understanding and reading capability. Like mathematics, programming also helps children open to problem-solving methods and think more logically, which can benefit them in the future.
The aim of this project is to develop a new compositor back-end, taking advantage of GPU acceleration to be performant enough for real-time interaction.
As a first step, this new back-end will be used to power the Viewport Compositor, a new shading option that applies the result of the Compositor Editor node-tree directly in the 3D Viewport. Artists will not have to wait for a full render to start compositing, allowing for faster and more interactive iterations on one’s projects.
For ants in particular, stigmergy is useful as it alleviates the need for memory and more direct communication; instead of broadcasting a signal about where a new source of food has been found, you can instead just leave a breadcrumb trail of pheromones that will naturally lead your community to the food.
We humans also use stigmergy in a lot of ways: most notably, we write things down. From post-it notes posted on the fridge to remind ourselves to buy more cheese to writing books that can potentially influence the behaviour of a whole future generation of young people.
Let's face it: We don't have infinite brains and we need to somehow alleviate the need to remember everything. If you remember the movie Memento, the protagonist Leonard has lost his ability to form new long-term memories and relies on stigmergy to inform his future actions; everything that's important he writes down in a place he's sure to come across it again when needed. His most important discoveries he turns into tattoos that he cannot lose or avoid seeing when he wakes up in the morning.
We are happy to announce the release of Qt Creator 8 RC!
Porting legacy code from Motif, MFC, Photon, or a previous Qt version to a more recent Qt version can be a big challenge. There are a number of pitfalls in a large porting effort that can significantly increase time, cost, and complexity, leading to risk of project derailment. You may have languages, frameworks, and windowing systems that are no longer supported or that leave you unable to find knowledgeable talent. On top of that, legacy UIs tend to look very dated compared to today’s fluid animations, context-sensitive controls, and responsive interactions, requiring more than just a simple port to bring them up-to-date. All of this may be so overwhelming that you aren’t sure where to even start.
I haven’t spent much time at my computer for a long time now. Partly because I’m busy with life in general, but also because I haven’t enjoyed computers (or technology in general) for a while now.
There’s just so much crap out there these days, that’s killing all the fun for me.
For decades, Microsoft spent great effort to scare the commercial software sector with stories of how FOSS (and Linux in particular) were not commercially viable products. Microsoft even once claimed that anyone who developed FOSS under copyleft was against the American Way. Today, there are many developers who make their living creating,supporting, and redistributing FOSS, which they fund (in part) by charging for FOSS on app stores. We in the FOSS community have long disagreed with Microsoft: we have touted that FOSS provides true neutrality regarding commercial and non-commercial activity — both are permitted equally. In short, our community proved Microsoft wrong with regard to the commercial viability and sustainability of FOSS.
Sadly, these days, companies like Microsoft have set up these app stores as gatekeepers of the software industry. The primary way that commercial software distributors reach their customers (or non-profit software distributors reach their donors) is via app stores. Microsoft has closed its iron grasp on the distribution chain of software (again) — to squeeze FOSS from the marketplace. If successful, even app store users will come to believe that the only legitimate FOSS is non-commercial FOSS.
Ravie Lakshmanan's recent article CISA warns of active exploitation of 'PwnKit' Linux vulnerability in the wild articulates the vulnerability in Polkit (CVE-2021-4034) and recommends "to mitigate any potential risk of exposure to cyberattacks… that organizations prioritize timely remediation of the issues," while "federal civilian executive branch agencies, however, are required to mandatorily patch the flaws by July 18, 2022."
Security updates have been issued by Debian (intel-microcode), Fedora (dotnet3.1 and gnupg2), Oracle (grub2, kernel, php:7.4, php:8.0, and qemu-kvm), SUSE (389-ds, apache2, crash, curl, expat, firefox, fwupd, fwupdate, ImageMagick, ldb, samba, liblouis, librttopo, openssl, openssl-1_0_0, openssl-1_1, openssl-3, oracleasm, php7, php8, python-Twisted, python310, rsyslog, s390-tools, salt, thunderbird, and xen), and Ubuntu (linux-lts-xenial, linux-kvm and openssl).
Kali Linux is a Linux distribution designed for penetration testing or -- yes -- hacking. This Debian-based Linux is a security worker's favorite distribution. And, now Linode, which recently became part of Akamai, is offering Kali as a supported distribution.
Cisco has released security updates to address vulnerabilities in multiple Cisco products. An attacker could exploit some of these vulnerabilities to take control of an affected system. For updates addressing lower severity vulnerabilities, see the Cisco Security Advisories page.
MITRE has released its latest list of the top 25 most exploited vulnerabilities and exposures found in software.
The MITRE CWE list is different from the product-specific CVE lists from the U.S. Cybersecurity and Infrastructure Security Agency (CISA) and other agencies and instead focuses on more generic software development weaknesses, similar to the OWASP list for web applications.
MITRE’s latest CWE Top 25 Most Dangerous Software Weaknesses list contains a number of significant changes, such as a big jump in Race Condition attacks (CWE-362) and Command Injection attacks (CWE-77).
MITRE said its goal is to help professionals handle and mitigate various risks, which includes software for “architects, designers, developers, testers, users, project managers, security researchers, educators,” and many other contributors.
The ranking is a great resource for everyone from developers to defenders and security teams, as it lists bugs that are actively exploited in the wild and have a significant impact.
Report by Georgetown’s Center on Privacy and Technology published a comprehensive report on the surprising amount of mass surveillance conducted by Immigration and Customs Enforcement (ICE).
Twitter's decision to reject Indian demands that it take down content and block accounts the government dislikes shows a tough new tack by social media giants that analysts say could set a precedent in the face of growing regulatory crackdowns.
On Tuesday, the U.S. social media platform asked an Indian court to overturn some of the government orders to kill posts, which Delhi had accused of spreading misinformation.
They included posts that backed farmer protests and tweets critical of the government's handling of the COVID-19 pandemic.
Losing connectivity in today’s Myanmar is life-threatening. When access to the internet, phone, and call services are curtailed and people are unable to communicate, they cannot contact their families, get critical information for their safety and protection, or expose the serious human rights violations that continue to escalate. The anti-coup resistance movement in Myanmar will be paralyzed if the military junta is given unbridled authority to decide who can access critical phone services and who gets cut off.
That is exactly what will happen if the military junta succeeds in implementing its plan to require registration of all International Mobile Equipment Identity (IMEI) numbers for mobile devices in Myanmar. An IMEI number is the unique identification number assigned to a mobile device – such as a cellular phone – by its manufacturer. According to the latest reports, the junta-controlled Ministry of Finance and Planning met with telecom operators on 7 June 2022 to discuss implementing the plan.
The registration requirement gives the people of Myanmar only dangerous choices: to register and be subjected to deeper surveillance, or to refuse to register and be unable to call, text, or access the internet through one’s phone.
Who am I? Its a fairly simple question. Three words, 6 characters (okay 8 if you include spaces), is all is needed to encode in english one of the most profound and fundimental questions of human experience. From philosophers to psychologist to theologist to neuro-scientist. Every culture of decent intellect tries to tackle the question of conciousness and its ethereal nature as well as the seemingly paradoxical nature of our own conciousness being able to try and analize itself. An observer trying to look at its own self and ponder the mystery of observation itself.
The longer one thinks about it, the more existantially uncomfortable one becomes. A conciousness trying to understand the nature of itself. Define and box our own selves into understandable chunks, rationalizations of why we do what we do, like what we like, hate what we hate, and think how we think.
As a result, I will likely not be posting much on my log. I will, however, continue to be reading Gemini, and I will continue to be reachable via e-mail and other methods of contact.
* Gemini (Primer) links can be opened using Gemini software. It's like the World Wide Web but a lot lighter.
