    • Welcome to the New (and Much Lighter) Tux Machines News Section

      LAST night we made the final changes — alternations that have been planned since June. The migration has thus far gone smoothly. The “old” site is still there, working as before, but new stories will be posted only here.

      As noted above, this site’s CMS (custom-made) is still in its “testing” phase. It seems to have matured enough for a ‘stable’ deployment (fingers crossed; famous last words!). We do expect some bugs. We’ve already heard from readers who have suggestions. They’re being added to our TODO list.

      Do you have further feedback on the site? Come and tell us in IRC. It’s the best and the quickest way to contact us.

      • Its FOSSDesktop Linux Market Share: August 2022

        Of course, Linux dominates the entire cloud industry (Web host, cloud computing, data warehouse, etc.). Here, we focus only on the desktop Linux market share.

        One day, we hope that Linux distributions dominate the desktop operating market share in the future. But, what do the current trends say? Is it the year of the Linux desktop yet?

        The trends change every month. Last year, Linux could have a better grip over the market share compared to this year. So, it is vital to track the latest reports.

    • Kernel Space

      • /bɑs ˈtjɛ̃ no ˈse ʁɑ/ (hadess) | News: Speeding up the kernel testing loop

        When I create kernel contributions, I usually rely on a specific hardware, which makes using a system on which I need to deploy kernels too complicated or time-consuming to be worth it. Yes, I’m an idiot that hacks the kernel directly on their main machine, though in my defense, I usually just need to compile drivers rather than full kernels.

        But sometimes I work on a part of the kernel that can’t be easily swapped out, like the USB sub-system. In which case I need to test out full kernels.

        I usually prefer compiling full kernels as RPMs, on my Fedora system as it makes it easier to remove old test versions and clearly tag more information in the changelog or version numbers if I need to.

        [...]

        Easy enough. Now we can use fedpkg or rpmbuild to create RPMs. Don’t forget to run those under “powerprofilesctl launch” to speed things up a bit.

        [...]

        I believe there’s still significant speed ups that could be done, in the kernel, by parallelising some of the symbols manipulation, caching the BTF parsing for modules, switching the single-threaded vmlinux bzip2 compression, and not generating a headers RPM

      • WCCF TechAMD CPU microcode loading to be optimized to per-thread on Linux

        Previously, any new processor microcodes for AMD-based CPUs had to be checked to guarantee that the open-source developers working with the company installed each physical core with the latest microcode. Not only did this leave out updates for coinciding threads for SMT processors, but it would be a lengthy process, which this new update will fix the per-thread updating within Linux.

        “It’s crucial to manage storage capacity on a Linux system. Programs that act as package managers, for instance, alert you to the amount of disc space needed for setup. You need to be aware of the amount of free space on your machine for that knowledge to be useful. There are several utilities available in the Linux systems to discover what is using the disk space of our system. Discover how to examine the disc space in Ubuntu using the df utility as well as how to view the file system’s disc space consumption using the “du” tool throughout this lesson.”

      • ID RootHow To Install Linux Kernel 5.19 on Ubuntu 22.04 LTS – idroot

        In this tutorial, we will show you how to install Linux Kernel 5.19 on Ubuntu 22.04 LTS. For those of you who didn’t know, Linux Kernel is a free and open-source, monolithic, modular, multitasking Unix-like operating system. It is the main component of a Linux operating system and is the core interface between the computer’s hardware and its processes. Linus Torvalds announced the Linux Kernel 5.19 which is available to download for general usage with new features, Major ARM updates, improvements, better hardware support, and other new updates.

        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 Linux Kernel 5.19 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.

      • Red Hat OfficialHow to configure a hostname on a Linux system

        Each person has a unique identity, such as their name and birth date. Computers also have individual identities, specifically, their hostnames and internet protocol (IP) addresses. Each machine has a valid IP address, but referring to a system by its IP address is not practical.

        Instead, you can configure a computer’s hostname, which is the machine’s human-friendly name. You can map the hostname to the IP address so that it’s easy to connect to a machine using its name.

        If you are a beginner Ubuntu user or recently upgraded to Ubuntu 22.04, you may wonder how you can play mp4 files. By default, Ubuntu lacks the needed multimedia codecs to support mp4 files, especially if you want to play a locally stored video. It gets worse when you try opening your favorite platform like YouTube or Facebook or when you try to load the live videos and you get the annoying error that your browser can’t play the given video file.

          Happy traveller is back. Happy open source conference guy is ready for another trip. This time my destination is KDE Akademy and Barcelona. It’s my first time attending to Akademy and I am soooooo excited. It’s also my second time in Barcelona.

      • GNOME Desktop/GTK

        • The Register UKThere’s no place like GNOME: Project hits 25, going on 43

          The two original developers behind the GNOME project started work 25 years ago, and the 43rd version of their brainchild is nearly here.

          The GNOME project is celebrating its quarter century, not long behind that of the KDE project, whose version 5.23 was its corresponding birthday last year. They’re close for a reason, but it’s ancient history in Linux terms.

          As we’ve covered in some depth before, KDE uses the Qt toolkit, which is written in and designed for use with C++. When the KDE project started, Qt wasn’t GPL. As a result, Red Hat refused to bundle KDE with its distro (which is how Mandrake Linux got started – it was Red Hat Linux, but bundled with KDE).

          A second issue is that Linux is mostly written in C, just like Unix before it. Some traditional Unix types remain suspicious of C++ and prefer to avoid it. The result was GNOME – a desktop written in C, using the all-GPL GTK toolkit. For years thereafter, if you installed Red Hat Linux, you got GNOME.

        With many enterprise edge computing strategies still in their early days, edge security could likewise appear as a new – a potential risky – frontier.

        The highly distributed nature of edge computing does expand an organization’s threat surface and overall complexity. But edge itself shouldn’t be viewed as scary or insecure – security just needs to be properly prioritized, much like your cloud and on-premises environments.

        “Edge computing can create more complexity, and this can make securing the entire system more difficult,” says Jeremy Linden, the senior director of product management at Asimily. “Still, there is nothing inherently less secure about edge computing.”

        The big edge security risks should sound familiar – compromised credentials, malware and other malicious code, DDoS attacks, and so forth.

      • Daniel PocockDebian & Open Source volunteer suicides: who pays compensation?

        The comparisons between the Debian Day suicide and Amnesty International suicides have resonated with many people. We see similarities in the way these people died but dramatic differences in the way organizations respond. Amnesty commissioned a public report about each case. Debian fought tooth-and-nail to keep the details secret.

        After the Amnesty suicides, somebody leaked details about a €1 million (£800,000) compensation payment to the family of one victim.

        Debian financial backers like Ubuntu and Google may not want to make a similar payment. Could this be the reason some Debian people want to maintain secrecy about the suicide? Over the last twenty-four hours, they have launched an unprecedented pestering campaign to have moderators purge references to Frans Pop from online forums, Reddit and social media.

        When the misfits start one of these pestering campaigns, forum owners only see one side of the story, the five or six misfits clicking the “report” button over and over again. Even if this noise comes from less than one percent of the community, if the other ninety-nine percent are simply passive then the moderator might be duped or might simply remove a post as a result of fatigue. There is no button for people to click to “un-report” a post so the majority of people who value these posts are largely invisible.

        [...]

        Due to the way so much of Debian activity is conducted through electronic channels that are not visible to employers and families, his family may be completely unaware how much unrelenting pressure Frans Pop experienced.

      • Its FOSSWhat’s the difference between apt-get upgrade vs dist-upgrade?

        Are they the same, or is there a difference? In which cases should you use apt-get upgrade and when should you use apt-get dist-upgrade?

        In this article, I’ll explain the difference between apt-get upgrade and dist-upgrade. I’ll also discuss how apt upgrade and apt full-upgrade do things differently.

        • Linux HintNull in C++

          A null pointer points to nothing. The default constant null has a value of 0. Similar to how C++ end strings, the character 0 is used to end strings. Null is another possible value for a pointer, and unless the CPU supports a particular bit pattern for null pointers, it has the same meaning as zero. Something has no value when marked with the SQL special marker null or referred to as NULL. Frequently used as a separator, terminator, or filler is the zero-valued ASCII character known as “null” or “NUL”. This symbol has no visible representation. An object pointer (or reference) not currently set to point to an object is known as a null pointer or reference. It may also be written as None, NULL, or nil.

        • Linux HintDefault Constructor in C++

          “When an object is created in C++, a special technique named the function Constructor is immediately called. In general, it is utilized to configure member functions of new classes. In C++, the class name serves as the title of the Constructor. Whenever we create an object, we have to invoke the Constructor. It creates the values, i.e., supplies the element with data; this is why it is referred to as a Constructor.

          The default constructor is utilized to generate the objects without a predefined initial value. A constructor can have default parameters as well as default values. If the user does not specify a default constructor, the compiler may automatically construct one and define it as required. Some configurations of the class intervals must be performed by the default constructor specified by the compiler. But depending on the situation, the compiler creates instructions for the default constructor.

          We’ll go over the default constructor’s functionality in this article.”

        • Linux HintC++ Comments

          “The purpose of comments is to serve as a reminder to you and to let others know how your program works. Large text code explanations and code snippets that need to be commented out while debugging applications are both examples of multiline comments. The compiler doesn’t take comments into account. The comments in C++ can be one or more lines long. Any character that is present inside a comment is disregarded by the C++ compiler. Your comments should make it possible for outside users to understand your code.

          If comments regarding program details are not supplied, someone reading a huge amount of code will be perplexed. Making a code more comprehensible by adding extra descriptions is possible with comments. To make the code understandable, comments may contain an algorithm description. If code needs to be reused after a significant break, comments can be useful for the individual as well. Comments shouldn’t be used as a stand-in for an English language explanation of badly written code. Writing clean, self-explanatory code should always be a priority. Next, use the comments section.”

          “Maps are associative containers that are used to store objects in a mapped manner. Every key in a key-value pair containing all the components of a map is distinct. Keys are used for ordering, but every key has a set of related values. Data could be added and removed when needed. In the C++ programming language, maps hold items created by combining a key value and a defined value.

          For two primary purposes, C++ programmers may find the map structure useful. First, by use of the key, a map enables quick and easy accessibility to the value. Creating any type of index or pointer can benefit from this attribute. A key must be unique throughout the integrated data framework, which the map provides to do. This prevents data duplication; therefore, it is another benefit of using the map.

          For example, if you’re creating a trading app and have to keep asset values by ticker sign, a map is a useful approach due to these two benefits. A map would be an efficient method to provide and check the existing weather in many cities all over the world if we had been developing a weather app. We will probably use a map at an online marketplace to locate products by brands or categories.”

        • Linux HintAbstract Classes C++

          “A class in C++ Programming language is considered abstract if it contains at least a single virtual method. The virtual method can be defined by the classes that inherit the abstract class; otherwise, the subclass would have become an abstract class. Abstract classes have been used to construct the C++ APIs; however, data abstraction, which will be the idea of maintaining configuration settings apart from associated data, may not be mixed up with abstract methods. An abstract class operates as a base class from which certain classes may derive. Let’s see the different examples of an abstract class.”

          Keep in mind that you will require a Mapbox account and access token to access the Mapbox API and create various types of plots.

          To learn more about that, check our tutorial on the plotly set_mapbox_access_token function.”

          This article focuses on Python packages location in different Linux distributions.

          By reading this tutorial, you will learn where the Python packages and modules are installed in your system and other Linux distributions. But the most important teaching in this tutorial is in the last section, where you will learn how to find the Python packages without memorizing the directories independently of the Linux distribution or installation method.

          All examples shown in this article include screenshots, making it easy for every Linux user to understand them independently of their knowledge level.

        • Linux HintNumPy.Square

          The square function in NumPy allows you to perform an element-wise square of an input array. Once you provide an array, the function will return an array of similar shape with each element in the source array squared.

          This function does not perform the operation in-place. Hence, the input array remains unchanged.

        • Linux HintDecorators in Python

          Python’s decorators are an extremely helpful feature as they let the programmers customize how a method or class behaves. Decorators enable us to encapsulate another function to modify its functionality temporarily while extending the functionality of the wrapped method. Let’s first comprehend a few concepts that would be helpful while learning about decorators before we get too deeply into them.

          After being directed by the Delhi High Court to respond afresh to our RTI requests seeking information on use of facial recognition (FRT) in policing, the Delhi Police has revealed that it treats all results above 80% similarity as positive results. Read our analysis of the responses received below.

          RTI responses shine new light on how the Delhi Police uses FRT

          In 2020 and 2021, we filed three RTI requests with the Delhi Police seeking information on their use of FRT. The information was refused under Section 8 of the RTI Act. Some information was refused on the ground that it is not available. The Delhi Police also said they have “Nil” information on CCTV cameras! Our first appeals against these responses were rejected, so we filed Second Appeals with the Central Information Commission. They were heard on June 29, 2022, and the Delhi Police were directed to revise their response to the RTI applications, in compliance with the RTI Act.

        Access Now, Amnesty International USA, Fight for the Future, Human Rights Watch, and Planned Parenthood Federation of America are calling on Meta to come clean in regards to its dangerous censorship of reproductive rights content in a post-Roe world.

        In the weeks following the Dobbs v. Jackson Women’s Health Organization decision, reports began to emerge detailing cases where Meta censored reproductive health-related information in the United States, including posts and hashtags that used the words “abortion pills” and abortion medication “mifepristone.”

        Then news broke that Facebook turned over the messages of a teenager in Nebraska to law enforcement over charges that she broke a state law banning abortions after 20 weeks.

        These cases are incredibly alarming when it comes to Meta, its platforms, and how (or if) it intends to protect peoples’ rights to seek, receive, and impart information related to sexual and reproductive health. While the company has made public comments about plans to protect its employees’ access to reproductive healthcare, it has not said if it will do the same for the millions of people who use its platforms in the U.S.

        Civil society calls on the company to clarify how and why Meta’s Community Standards and other policies led to the removal of abortion-related content, and to assess whether these policies contravene the human right to abortion.

      • Internet Freedom FoundationMonsoon Session 2022: A Digital Rights Review

        The Monsoon session of Parliament was held from July 18, 2022 to August 8, 2022. Parliament adjourned sine die two working days ahead of schedule, having sat for 16 days. In the ongoing 17th Lok Sabha, this is the seventh consecutive session that has been cut short. This session saw the election of the new President and Vice President (who is also the Chairman of the Rajya Sabha). Debates on several prominent issues, including discussion on price rise, led to frequent disruptions during the Monsoon Session. Approximately 23 Members of Parliament (“MPs”) were also suspended during the course of the session. In this post, we take a look at these disruptions, suspensions, bills passed/ withdrawn and analyse how the Parliament fared with respect to digital rights. Unfortunately, from a key legislation on data protection being withdrawn to parliamentary questions posed by suspended MPs going unanswered, the parliament saw very limited activity.

        [...]

        This Monsoon Session was a huge setback for digital rights: the withdrawal of the DPB, 2021 sent us back more than four years, when the consultation process for the data protection legislation began. The upcoming ‘comprehensive legal framework’ will set the tone for India’s data protection regulatory regime and thus it is essential that the comments, feedback and deliberations serve to inform the government about the issues that various stakeholders, especially the civil society, want a data protection legislation to address. Thus, we hope that when the government finally presents the new Bill, it conducts comprehensive public consultation and discussions on the Bill in Parliament, and provides its rationale for either accepting or rejecting each of the recommendations of the JPC. We also hope that in the upcoming sessions, parliamentary procedures are conducted in good faith, such that we are able to fathom the veracious account of digital rights in India.

        The United States Inflation Reduction Act of 2022 is poisoned.

        It’s bad enough that it divided the climate money by ten and then changed it to be about “energy security” (probably better known as drill mania), taking our earmarked climate change save-the-world money and instead dedicating much of it to burning the world.

        I have always liked writing digitally, particularly because of the speed at which you can convey thoughts and the easy formatting. Recently, I have taken a new approach towards writing: putting my thoughts down on paper then transcribing them here.

        Writing on paper is a whole different environment from digital writing, so I will discuss various aspects of it.

        • Capsule design

          Recently, I have re-designed my capsule, inspired by a post from idiomdrottning[1] about designing your capsule for simplicity.

          I switched from using the ISO8601 format dates in the URL, to including the full post title, no date. The date could induce FOMO as in “oh, what other posts are there this is from N date”, while I do not want it to be that. Besides, the principle of presenting every resource as a first-class citizen is a good idea, not piggy-backing off your posts in order to redirect people to your capsule. The content matters, not views.

          Although, the URLs might get a tad too long if there is a lengthy title, I will see how I shorten it, perhaps not including linker words.
