  • Fedora Community Blog: Some docs repos are moving to GitLab

    The Fedora Docs team is starting the process of moving repos from the fedora-docs namespace on Pagure to GitLab. We’re making this move in order to take advantage of features like improved in-browser editing and cross-repo kanban boards. This move will be entirely transparent to the docs published at docs.fedoraproject.org. However, if you are contributing to one of the repos in this namespace, you’ll need to update the git remote.

  • Red Hat 2022: Linux In a New Avatar, OpenShift Upgrades, and Other Announcements
  • Is the new open source standard no standard at all? | TechRepublic

    We’re in a strange, somewhat unpredictable period in open source that has been caused perhaps by a lessening of Red Hat’s industry impact over the years. On Twitter, Brianna Wu asked men over 40 to comment on “structures [that] existed in your life to teach you how to be a good man.” Answers included things like Boy Scouts. A similar sort of question might be asked of developers and “open source structures…to teach you how to be a good open source citizen.”

    When I got started in open source, the obvious answer to most every question was “Red Hat.” What’s the right way to build a business in open source? Look to Red Hat was the stock response. What’s the right way to advocate for code freedom in open source? Again, look to Red Hat.

  • Return String From Function C++

    A way to identify a series of strings as a class member is specified in C++’s definition. The String class holds attributes as a stream of bits, with the ability to handle a single-byte character. In C++, we may retrieve a string, but we should still examine how the string will be retained and transferred. Because C++ returns elements on the heap, which has a finite amount of space, providing immense components will induce stack overflow issues that could result in errors and security flaws.

    If we can return a std::string object from the standard template library, we may provide a constant pointer to the string. Ascertain that the string is retained in static memory. This article outlines various approaches for returning a string from a C++ function.

Emulate the VIC-20 home computer with Linux

Sob, 05/21/2022 - 12:24

Emulation is the practice of using a program (called an emulator) on a PC to mimic the behaviour of a home computer or a video game console, in order to play (usually retro) games on a computer.

Home computers were a class of microcomputers that entered the market in 1977 and became common during the 1980s. They were marketed to consumers as affordable and accessible computers that, for the first time, were intended for the use of a single non-technical user.

Back in the 1980s, home computers came to the forefront of teenagers’ minds. Specifically, the Amiga, ZX Spectrum, and Atari ST were extremely popular. They were hugely popular home computers targeted heavily towards games, but they also ran other types of software.

The Commodore VIC-20 is an 8-bit home computer that was released in 1980/1. It featured a MOS Technology 6502 CPU, with 20KB ROM and 5KB RAM although 1.5K of the RAM was used for the video display and aspects of the BASIC and kernal.

It offered limited low-resolution graphics (176 x 184) with storage provided by cassette and floppy disk.

    Most modern Linux distributions have out of the box outstanding support for most of the available hardware components, like your graphics card, printer and WiFi adapter. Even for many relatively new hardware technologies there is support with the help of Hardware Enablement. But it is always possible that the setup procedure doesn’t come up directly with the correct or most optimized drivers for your specific internal or external devices. In this article as part of my Zorin OS tutorial series I will focus on the support of graphics cards and will show you how to install or update graphics drivers in Zorin OS.

FSF Does Not Accept Debian as a Free Distribution. Here's Why!

Sob, 05/21/2022 - 12:05

The Debian Project develops a free GNU/Linux distribution that respects the freedom of its users. It’s not uncommon for software, the source code of which is distributed under this or that free license, to contain non-free components. In this case, the software is cleaned before being released into Debian. The Free Software Foundation (FSF), in turn, maintains a list of free GNU/Linux distributions, but oddly enough, Debian is not there. The fact is that Debian does not meet some criteria for getting on this list and we have to figure out which ones. But first, you need to understand how all this intellectual work is justified. In other words, why bother trying to get on some lists and this one in particular?

Stefano Zacchiroli, who used to be the leader of the Debian Project from 2010 to 2013, once voiced several reasons why Debian should have got the FSF to obtain the status of free distribution. One of these reasons, which Stefano called “external review”, I especially liked. The fact is that Debian has criteria and quality standards that software must meet to become part of the distribution, but no one except the Debian developers themselves controls this process. If the distribution had been included in that cherished list, the FSF would have been keeping a close eye on the fate of Debian with moderate criticism. Excellent motivation, I believe. If you also think so, then let’s now have a look at the reasons why the FSF considers Debian as not free enough.

  • This Week In Security: IPhone Unpowered, Python Unsandboxed, And Wizard Spider Unmasked

    As conspiracy theories go, one of the more plausible is that a cell phone could be running malicious firmware on its baseband processor, and be listening and transmitting data even when powered off. Nowadays, this sort of behavior is called a feature, at least if your phone is made by Apple, with their Find My functionality. Even with the phone off, the Bluetooth chip runs happily in a low-power state, making these features work. The problem is that this chip doesn’t do signed firmware. All it takes is root-level access to the phone’s primary OS to load a potentially malicious firmware image to the Bluetooth chip.

  • Ransomware Deals Deathblow to 157-year-old College [iophk: Windows TCO]

    Illinois-based Lincoln College was established during the U.S. Civil War. Since then it has weathered two world wars, the Spanish Flu, the Great Depression, the Great Recession and a devastating fire. But two things it couldn’t survive?

    A ransomware attack and financial pressures tied to the impact of COVID-19 on its enrollment.

  • Total Commander forced to stop letting you install APKs

    One of the handiest features on Android that sets it apart from the mobile competition is the ability to install apps from outside the Play Store. APK installation is why you can still play Fortnite — even as Epic's legal battle with Google continues — and it's how you can skip the wait for automatic updates to bring the latest features to your favorite apps. Unfortunately, one of Android's most trusted file browsers has removed the ability to install APK files after receiving takedown warnings from Google.

    Total Commander has been around since the 90s, eventually expanding into Android after the platform launched over a decade ago. The app has more than 10 million downloads on the Play Store, still supporting OS versions as far back as Android 2.2. With a new update, developer Christian Ghisler has removed the ability to install APK files on Android, blaming Google Play policies in the patch notes for the app. It's a shocking twist for the service and, seemingly, a bad omen of things to come for other mobile file managers.

  • Bernd Rodler: Real Innovation And Progress Happen Beyond Big Tech (Part I ) – Interview

    In 1991, Linus Torvalds started this fantastic Linux project and prior to that, Richard Stallman came up with the idea of GPL, the general public license. Thus, a new model to deliver software code in an open and transparent manner came into existence. Stallman can be quoted with the famous phrase: „If you think about open source, think free as in free speech, not free beer.“ After GPL and the first Linux kernels gained ground, more and more open source based business software was developed.

    The US Justice Department has directed prosecutors not to charge "good-faith security researchers" with violating the Computer Fraud and Abuse Act (CFAA) if their reasons for hacking are ethical — things like bug hunting, responsible vulnerability disclosure, or above-board penetration testing.

    Good-faith, according to the policy [PDF], means using a computer "solely for purposes of good-faith testing, investigation, and/or correction of a security flaw or vulnerability."

    Additionally, this activity must be "carried out in a manner designed to avoid any harm to individuals or the public, and where the information derived from the activity is used primarily to promote the security or safety of the class of devices, machines, or online services to which the accessed computer belongs, or those who use such devices, machines, or online services."

We decided to write a quick tip on how to add a comment to UFW (Uncomplicated Firewall) rules.

    I am not a huge fan of UFW or Firewalld. In my opinion they make managing netfilter harder, not easier. That is because I started using iptables over 20 years ago. I am very comfortable with it and tend to know the necessary syntax off the top of my head. That being said, adding a comment to UFW rules is much more intuitive than any other iptables front end.

GNOME and KDE: This Week in GNOME, Qt6 and KF6

    Update on what happened across the GNOME project in the week from May 13 to May 20.

  • Okteta making a small step to Qt6 | Attracted by virtual constructs

    Old, but stable, even more in when it comes to the feature set, and still getting its polishing now and then: your simple editor for the raw data of files, named Okteta.

    What started in 2003 as a hex editing widget library for KDE3 (and Qt3), of course named KHexEdit (to be confused with the unrelated hex editor program that was part of KDE at that time), it turned into a first dedicated application by the title Okteta during the years 2006 to 2008 for KDE4 (and Qt4). From there on a small set of features was added once in a while, most impressively Alexander Richardson’s Structures tool in 2010,. Until then in 2013 the port to Qt5/KF5 was done (also to a good degree by Alexander). After that things had settled, the program working properly when needed, otherwise just left in the corner of the storage.

    Now, nearly 2 decades after the first lines were written, the next port is to be done, to Qt6 and KF6. And this time the actual port is just amazingly boring: changing a few “Qt5” to “Qt6” in the buildsystem (and later some “KF5” to “KF6” once KF6 is ready), adding Qt6::Core5Compat as helper library for 1-2 classes that had not yet been substituted, adding a “const” to the argument of an overridden virtual method, adapting some “QStringList” forward declarations… and done.
