GhostBSD Review: Simple and Lightweight

Filed under
Reviews
BSD

Because there are so many different options out there for your free and open-source operating system, it can be hard to figure out what the best option is for you. Sifting between Linux distros is difficult – Debian and its derivatives, Ubuntu and its derivatives, Fedora, Arch, openSUSE, the list goes on. However, what if the best choice for you isn’t actually technically Linux? Here we review GhostBSD, a FreeBSD-based Unix OS designed for a simple desktop experience, to see if it’s the right fit for you.

[...]

The applications that are installed are all necessary. It’s exactly what you might expect to find in your typical lean open-source desktop OS configuration, with no frills and just the essential applications.

There is not much to remark on with the user experience – it is a very simple and friendly version of the MATE desktop that’s designed to be light on system resources and simple to use. Overall, I think there is no way you could go wrong.

  • Thrilling Linux Gaming Predictions for 2021 - Boiling Steam

    Last week we reached out to the community at large with a simple question: What do you predict will happen in the world of Linux Gaming by the end of 2021? To make things a little more fun, we asked everyone to limit their Linux Gaming predictions to 5 items, and be as specific as possible as to what they expect to occur. We also asked everyone to work on their predictions individually to avoid any potential bias.

    Now, we are sharing with you all the predictions we received, from quite a few places across the world as you can see from the below map. The Linux Gaming Community knows no frontiers.

  • Team Cherry upgrade the excellent Hollow Knight with Vulkan for Linux | GamingOnLinux

    Team Cherry have given their excellent action-platformer metroidvania Hollow Knight a bit of an upgrade, which you can test out on Steam in a fresh Beta test.

    Not played it before? You're missing out. Hollow Knight is a classically styled 2D action adventure across a vast interconnected world. Explore twisting caverns, ancient cities and deadly wastes; battle tainted creatures and befriend bizarre bugs; and solve ancient mysteries at the kingdom's heart.

  • OpenLoco is a free and open source re-implementation of Chris Sawyer's Locomotion | GamingOnLinux

    Just like there's the awesome OpenTTD for fans of Transport Tycoon Deluxe, there's also OpenLoco for players who want to play through the classic Locomotion. Not a project we've covered here before it seems, so we're making that right today.

    Originally released back in 2004, it's actually a spiritual successor to Transport Tycoon but it was not as loved due to various problems with the original release. Perhaps though it can have a new life thanks to OpenLoco.

  • VRWorkout is a free and open source VR fitness rhythm game

    Well, that's certainly one way to get a bit more exercise in. Whatever helps right? No judgement here, I could probably do with a little more myself…

    It's built with the free and open source game engine Godot Engine, so not only is the source code open for the game itself it's properly open for anyone to put it together from the source and will remain so. Speaking about VRWorkout to us on Twitter, the developer mentioned they actually do develop for it on Linux but they use a Quest headset not supported on Linux so they have to work with that on Windows. Perhaps though, in time, Monado might break down that barrier.

  • Free and open source voxel game engine Minetest 5.4 is out, makes mods easier for users | GamingOnLinux

    Minetest, the Minecraft-like voxel game engine (and a basic game that comes with it) has a big new release out with Minetest 5.4.0 and it's worth trying again.

    As we covered before during the Release Candidate stage, one of the big features for users in this release is vastly easier modding with both small mod packs and entire games. Minetest had a way to browse and download them all directly in the game for a while, but now it will also actually download all the dependencies mods need - making it vastly easier to get what you want and then into a game. No more downloading one mod, then finding all the individual bits it needs.

  • New service: https://debuginfod.debian.net

    Hello there,

    I would like to announce a new service that I have just configured for
    Debian: https://debuginfod.debian.net.

    debuginfod is a new-ish project whose purpose is to serve
    ELF/DWARF/source-code information over HTTP.  It is developed under the
    elfutils umbrella.  You can find more information about it here:

      https://sourceware.org/elfutils/Debuginfod.html

    In a nutshell, by using a debuginfod service you will not need to
    install debuginfo (a.k.a. dbgsym) files anymore; the symbols will be
    served to GDB (or any other debuginfo consumer that supports debuginfod)
    over the network.  Ultimately, this makes the debugging experience much
    smoother (I myself never remember the full URL of our debuginfo
    repository when I need it).

    If you would like to use the service, and if the service supports the
    Debian distribution you are using (see below), all you have to do is
    make sure that the following environment variable is set in your shell:

      DEBUGINFOD_URLS="https://debuginfod.debian.net";

    Currently, the elfutils and GDB packages in unstable and testing have
    native support for using debuginfod.  I will soon propose a change to
    the elfutils package in order to make it be configured with our
    debuginfod instance by default, so that users will be able to use the
    service transparently.

    For now, debuginfod.debian.net is serving debug information symbols for
    the following Debian distributions:

      - unstable

      - testing
      - testing-proposed-updates

      - stable
      - stable-backports
      - proposed-updates

    In the near future I intend to expand this list and include the
    debuginfo stored at snapshot.debian.org as well.

    Setting up a debuginfod service for Debian has been on my TODO list for
    some time now, and I finally got enough time & resources to do it.  I
    would like to thank a few people for their feedback and help:

      - Héctor Orón (zumbi)
      - Jonathan Carter (highvoltage)
      - Paul Wise (pabs)

    Last, but not least, you can find a wiki page about our service here:

      https://wiki.debian.org/Debuginfod

    Thanks,

  • Debian Launches A Debuginfod Server For Smoother Debugging Experience

    Debian is the latest major Linux distribution deploying a Debuginfod web server so that ELF/DWARF/source-code information can be supplied via HTTP to clients on-demand when debugging. 

    Introduced last year was Debuginfod with GNU Binutils 2.34 for distributing debugging information / source code on demand. Readelf and objdump utilities can query connected Debuginfod servers for source files / data based on a build ID. Debuginfod support was later integrated into the GNU Debugger too (GDB 10.1). The effort was led by Red Hat engineers while now Debian is getting in on this practical feature too.

  • Python While Loop: Intro and Explanation - Make Tech Easier

    Coding is (of course) about building things to help others. However, creating programs and software has more to do with automating repetitive or complex tasks than anything else. Python’s while loop lets you repeat suites of code to automate many actions at once.

    In this post, we show you how to use Python’s while loop. First, let’s talk about what the while loop does and where it’s best used.

  • Pattern dispatch | Playing Perl 6 b6xA Raku

    The ever helpful raiph wished for RakuAST in an answer to a question about pattern matching like it is done in Haskell. It was proposed to use MMD to solve this problem. Doing so and getting a fall-through default was unsolved. Since dispatch simply is pattern matching we just need to do some extra work. In a nutshell, the dispatcher gets a list of functions and a list with arguments. The first function that takes all arguments wins.

  • Clang LTO Support Merged For Linux 5.12 Including ARM64 + x86_64

    Pop open the champagne as the in-development Linux 5.12 kernel will be able to support link-time optimizations (LTO) in conjunction with the LLVM Clang compiler on not only AArch64 (64-bit ARM) but also x86_64.

    Last week I noted that Clang LTO support had been submitted but at the time was not clear if Linus Torvalds was willing to land it given his past comments around LTO'ing the kernel. With that pull request it was also just for AArch64 with the x86_64 support not yet squared away.

    Years ago Linus Torvalds was unconvinced by GCC LTO support for the kernel and that code ultimately was never mainlined. With Clang the benefits are much the same in allowing for potentially greater performance by allowing the code compiler to apply optimization passes at link-time on the entire kernel rather than being limited on a per source file basis. LTO also has the possibility of providing greater space savings too. Plus in the case of Clang, LTO for the kernel is also needed to support Control Flow Integrity (CFI) for the kernel.

  • add -ftrivial-auto-var-init and variable attribute "uninitialized" to gcc

    This is the first version of the complete patch for the new security feature for GCC:

    Initialize automatic variables with new first class option -ftrivial-auto-var-init=[uninitialized|pattern|zero]
    and a new variable attribute “uninitialized” to exclude some variables from automatical initialization to
    Control runtime overhead.

  • Proposed GCC 12 Security Option Would Auto Initialize Automatic Variables - Phoronix

    An Oracle engineer has proposed introducing a new "-ftrivial-auto-var-init=" option for the GCC compiler that would allowing initializing automatic variables with either a pattern or zeroes in the name of security.

    In trying to fight security issues stemming from uninitialized memory disclosure, the suggested -ftrivial-auto-var-init==zero would initialize automatic variables with zeroes unless the new "uninitialized" variable attribute was used on a particular variable for overriding the behavior.

  • An incomplete list of complaints about real code

    A couple of weeks ago, I got bored and decided to come up with a list of things that have bothered me when trying to run software to get things done. These might be reliability concerns, or development issues, or really anything else that bothered me at the time. This was actually pretty illuminating.

    I would actually recommend other people try it with their own annoyances and see how things stack up. It was interesting to look at the rows to see which choices were particularly bad because they hit so many of them, and then to look at the columns to see how often they showed up regardless of the language or environment.

  • Checkout Skimmers Powered by Chip Cards

    Easily the most sophisticated skimming devices made for hacking terminals at retail self-checkout lanes are a new breed of PIN pad overlay combined with a flexible, paper-thin device that fits inside the terminal’s chip reader slot. What enables these skimmers to be so slim? They draw their power from the low-voltage current that gets triggered when a chip-based card is inserted. As a result, they do not require external batteries, and can remain in operation indefinitely.

  • Why Was SolarWinds So Vulnerable to a [Crack]?

    Early in 2020, cyberspace attackers apparently working for the Russian government compromised a piece of widely used network management software made by a company called SolarWinds. The [attack] gave the attackers access to the computer networks of some 18,000 of SolarWinds’s customers, including U.S. government agencies such as the Homeland Security Department and State Department, American nuclear research labs, government contractors, IT companies and nongovernmental agencies around the world.

  • Google Disbands Stadia Game Developers And Signals Potential For More Trouble Ahead

    It's no secret that in the year and a half since Google launched its video game streaming platform, Stadia, things haven't gone particularly well. Game developers were wary at the onset that Google, as it has with projects like this in the past, might simply one day shut the whole thing down if it thinks the venture is a loser. The launch of Stadia itself was mostly met with meager interest, due to scant games available on the platform. Even then, the rollout was a mix of chaos and glitch, critiques of its promise for true 4k game streaming, very low adoption rates, and some at the company appearing to want to go to war with game-streamers.

  • John Deere Promised To Back Off Monopolizing Repair. It Then Ignored That Promise Completely.

    Five years or so ago, frustration at John Deere's draconian tractor DRM helped birth a grassroots tech movement dubbed "right to repair." The company's crackdown on "unauthorized repairs" turned countless ordinary citizens into technology policy activists, after DRM (and the company's EULA) prohibited the lion's share of repair or modification of tractors customers thought they owned. These restrictions only worked to drive up costs for owners, who faced either paying significantly more money for "authorized" repair (which for many owners involved hauling their tractors hundreds of unnecessary miles), or toying around with pirated firmware just to ensure the products they owned actually worked.

  • Spotify CEO Daniel Ek explains how the company plans to help artists (and itself) make money

    During the 90-minute event, the company rattled through a series of announcements. It detailed a slew of new podcasts, including one featuring former President Barack Obama and rockstar Bruce Springsteen as co-hosts, as well as a full universe of DC Comics programming. It debuted an expanded podcast ad marketplace, bolstered by its Megaphone acquisition and Streaming Ad Insertion technology, along with a Hi-Fi subscription tier. And it teased new tools for podcasters to engage with their audiences and make money through subscriptions. Spotify obviously intends to make podcasting a real revenue driver.

    But none of the announcements were groundbreaking for people in the industry. If anything, they demonstrated how far Spotify has yet to go. Crucially, Spotify announced that 7,500 musicians are making at least $100,000 per year through its platform, which isn’t much considering the service is available in 93 markets. Now, Spotify is trying to make the same pitch to podcasters as it did to musicians — that they’re all on the same side and share the same goals.

I have spent some time looking at independent Linux distributions – that means those that are built from scratch and not derived from one of the larger, generally better-known distributions (Debian, Ubuntu, Arch, etc.), such as Solus, which I wrote about earlier. This time I am going to look at KaOS Linux.

The screen shot above shows the initial display of a freshly installed KaOS system. If you are not familiar with the side-panel orientation used here, it is basically the same as the traditional bottom or top panel desktop, but with everything "standing on end". The complete desktop menu is at the top of the panel, just click on the "K" symbol (the desktop menu is open in this screen shot); the common application launchers are just below that, and the controls for things like the network, volume, bluetooth, network and such are at the bottom.

The Best Linux Distributions Without systemd

Filed under
GNU
Linux

Historically, the startup sequence in a Linux system was a replica of the initialization system that was introduced with System V Unix (SysV). The SysV init system adhered to the Unix philosophy. When people refer to the Unix philosophy, they usually reduce it to the well-known soundbite “Do one thing, and do it well.” And that thing was to start as the first process and then start other processes. It also culled zombies now and then.

SysV init did its job well enough, but it didn’t do it too efficiently. It started processes serially, one after the other. There was no parallelism. The design bottle-necked the throughput. This was more or less masked by the speed gains of modern hardware, and it’s not as if booting a Linux computer took an interminable age. But yes, technically, it could have been made more efficient.

As with everything else in Linux, the users had a choice. Alternatives were available. Competent users could configure their Linux computer to use a different init system, one that started processes in parallel and worked the way they liked.

Red Hat

Red Hat-based Linux distributions are shaping the industrial and corporate use of Linux for a long time. This project was quite popular since its initial release in 1995. Although later on, the developer company shut that down to start developing the successor named Red Hat Enterprise Linux (RHEL). This commercial project is mainly for deployment in multi-processor systems and cluster computing.

RHEL is a commercial project with enterprise support from the Red Hat company. So, to utilize the power of Red Hat Linux more easily and affordably, the open-source community has come up with derivatives based on the Red Hat source. These distros provide much flexibility and customization options. They are quite reliable and stable as well to deploy on your organization.

    If you look at your car’s dashboard, there’s a good chance you’ll find an efficiency rating for how you’re driving. However, what if you instead ride a hoverboard? This functionality is certainly not stock equipment, yet Niklas Roy wanted to understand the power consumption of his transporter during different riding situations. For that reason, he decided to develop a power monitor that not only graphs his stats when scooting around, but records the data for later viewing and analysis. Roy’s handheld device is controlled by an Arduino Nano and utilizes a Hall effect ammeter for current sensing. The measurements are shown as numbers and as oscillograms on a 1.8” TFT screen, which can also be logged to the display’s built-in SD card. An RTC module provides timestamp information for these readings, which can be produced using Processing and overlaid on video.

Documentation Improvements in KDE

Doxyqml, our documentation bridge between QML and doxygen, got various improvements, thanks to Olaf Mandel and Lasse Lopperi. Now QML enums are supported and the lexer/parser got various bug fixes. Speaking of QML documentation, the Kirigami API documentation was improved and now uses more correctly @inherit tags and @property tags. There is still room for improvements, but the current state is already a lot better. Most Components are now showing all their properties correctly and the type of the property is correct. (kirigami!239) Another improvement is that the generated Kirigami documentation now shows more accurate names: e.g. Kirigami.Page instead of org::kde::kirigami::Page. This makes it easier to read and navigate the documentation. There was also a bit of background work inside KApiDox, Jannet added support for QDoc, allowing to use QDoc as an alternative to Doxygen. This might be a better solution for generating documentation for projects with a lot of QML. Read more Also: MJ Inventory Released

  • What is Automation and Configuration Management with CHEF – Part 1

    Configuration Management is the key focus point of DevOps practice. In the Software development cycle, all the servers should be software-configured and maintained well in such a way that they should not make any break in the development cycle. Bad configuration Management can make system outages, leaks, and data breaches. Using Configuration Management tools is about facilitating accuracy, efficiency, and speed in the DevOps-driven environment. There are two models of configuration Management tools – PUSH-based & PULL-based. In the PUSH-based, the Master server pushes the configuration code to the servers wherein PULL-based individual servers contact the Master for getting configuration code. PUPPET and CHEF are widely used PULL-based models, ANSIBLE is a popular PUSH-based model. In this article, we will see about CHEF.

What is GNU/Linux Copypasta?

I’d just like to interject for a moment. What you’re refering to as Linux, is in fact, GNU/Linux, or as I’ve recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX. Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called Linux, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project. There really is a Linux, and these people are using it, but it is just a part of the system they use. Linux is the kernel: the program in the system that allocates the machine’s resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called Linux distributions are really distributions of GNU/Linux! Read more
