PCLinuxOS Roll-Up Release: Another Linux installed on my new notebook

Filed under
PCLOS
Reviews

I happened across a new ISO image for the PCLinuxOS KDE desktop distribution this week.

PCLOS is a classic rolling-release Linux distribution, so this is just a "roll-up" release, pulling all of the updates since the last release together to make new installations easier, faster and more reliable.

Every time a new rolling release update is made we talk about those first two points, how it makes installation faster and easier, but I think my recent experience with two ASUS laptops shows that the last point can be important as well.

PCLOS and blackPanther OS

  • Time for a change

    Three days ago, I decided to abandon my efforts to rescue my PCLOS KDE4 install, which was destroyed by a connection disruption while updating. I lost my connection for over a week and, when my ISP finally solved the problem, my desktop was so messed up that I gave up on it and decided to give PCLOS KDE5 a chance.

    I must confess that I am not a real fan of Plasma 5. However, as KDE4 is going the way of the dodo, I thought that it was better to take the leap and see how this beautiful Linux distro works with KDE's new desktop.

  • LinuxAndUbuntu Distro Review Of The Week blackPanther OS

    blackPanther OS is a Hungarian Linux distro. It takes out many features from other famous distros like GUI from fedora, drivers from Ubuntu and many others. The website of blackPanther OS states that:- “The blackPanther OS development started in 2002 by Charles K. Barcza. The First public version was 1.0 (Codename: Shadow) in 2003. Since then, the development is continuous, every year a new version is released. The last stable version, v16.1.2 has become available in Aug. of 2016. (The v16.2 is a special, non-free release, and v17.1 still under development) It was among the 5 top popular distributions January of 2010 on distrowatch.”

PCLinuxOS 2017.03

Reviews

It has been about a year since I last explored the PCLinuxOS distribution. At that time I was experimenting with the project's MATE edition. Since I have not taken the chance to try PCLinuxOS since the distribution launched an edition with the KDE Plasma 5 desktop environment, I thought it would be fun to revisit this project. PCLinuxOS currently ships with version 5.8 of the Plasma desktop which is a long term support release of Plasma. The ISO file I downloaded for PCLinuxOS was 1.3GB in size.

Booting from the distribution's live media brings up a menu asking how we would like to launch the operating system. We can choose to launch PCLinuxOS with a graphical desktop with the default settings, load the desktop with safe mode graphics settings, boot to a text console or launch the project's system installer. Taking one of the live desktop options soon brings up a window asking us to select our keyboard's layout from a list. Then the Plasma desktop loads. PCLinuxOS has a varied and colourful wallpaper. There are icons on the desktop which open the Dolphin file manager and launch the system installer. At the bottom of the screen we find a panel which houses the application menu, a few quick-launch buttons, a task switcher and the system tray.

Recreating the PCLinuxOS Full Monty with KDE Plasma Activities

Filed under
KDE
PCLOS

When I recently wrote about the new PCLinuxOS release, I was a bit disappointed to find that the Full Monty version had been laid to rest. I'm sure there were a lot of good reasons for this decision, and I have no quarrel with it. But it still made me a bit sad, because I have always kept the Full Monty on at least one of my systems (it is currently on my Acer All-In-One desktop), and I often showed it to people who were curious about Linux, as an example of its breadth, depth and flexibility.

So I decided that it might be a useful exercise for me to try to create the equivalent of the Full Monty desktop starting from the latest PCLinuxOS KDE5 distribution. There are two major features which distinguish the Full Monty desktop - it had six virtual desktops, each of which was dedicated to a specific use, and it had lots and lots and lots of packages installed. The desktops looked like this:

Latest Progress on KDE Themes and KTechLab

  • Week report 0

    Hello every one in the KDE planet and beyond, this is the progress weekly report on O². So The week surprisingly started Monday and after the initial chock and accompanying usual work day at KDAB, I decided to do a little bit of progress on O² style mock ups...

  • Announcing KTechLab 0.50.0

    I’m happy to announce KTechLab release version 0.50.0. KTechLab is an IDE for microcontrollers and electronics. In this new release every user-visible functionality is the same as in previous releases, however, the codebase of KTechLab has been updated, so now it is a KF5/Qt5 application and it does not depend anymore on KDELibs4Support libraries. This release should compile and run on systems where KDELibs4Support libraries are not available. In its current state KTechLab’s codebase is ready for fixes and enhancements, as it only depends on modern libraries like KDE Frameworks 5 (KF5) and Qt5. As a side note, KF6 and Qt6 have been announced, and the first release of Qt6 has been scheduled to the end of 2020.

  • KTechLab git master doesn't depend on deprecated Qt5/KF5 API anymore

    KTechLab git master doesn’t depend anymore on deprecated Qt5/KF5 APIs. Thank you for everybody who made this possible! Using only up-to-date APIs should help with long-term maintenance of KTechLab and probably it helps distributors of KTechLab, too.

Review: Garuda Linux 200817

One of the more recent additions to the DistroWatch database is Garuda Linux, an Arch-based distribution that offers several enticing features. By default Garuda is intended to be run on the Btr file system, which offers all sorts of attractive features such as multi-disk storage volumes and snapshots. Btrfs has been paired with Timeshift on Garuda and the system is reported to take automatic snapshots before each package upgrade, making the system much easier to recover. I especially like the idea of having automated filesystem snapshots on a rolling release distribution such as Arch. The openSUSE Tumbleweed rolling release has offered automatic snapshots of the system prior to upgrades for a while now and it is nice to see this feature catching on in other projects. The Garuda distribution ships with the Calamares system installer to make setting up the operating system easier. We are also given a desktop tool for managing drivers and Garuda's website mentions proprietary NVIDIA video drivers are optionally available. Rounding out some of the key features, Garuda ships with the Zen Linux kernel with the goal of providing better desktop performance. Read more

Linux 5.9-rc6

  • Linux 5.9-rc6
    Another week, another rc, and things look fairly normal: the diffstat
    looks fairly flat (implying small changes) and we don't have any
    unusual amount of activity.
    
    The one thing that does show up in the diffstat is the softscroll
    removal (both fbcon and vgacon), and there are people who want to save
    that, but we'll see if some maintainer steps up. I'm not willing to
    resurrect it in the broken form it was in, so I doubt that will happen
    in 5.9, but we'll see what happens.
    
    The other stats also look normal: about 60% of the patch is drivers
    (and yes, the softscroll is a noticeable part, but not overwhelmingly
    so - there's sound, gpu, mtd, i2c, usb etc). And the usual arch
    updates, along with some vm fixes (including the fix for the
    performance regression noted last rc) and perf tooling updates.
    
    We also have a (test regression (not the performance one) in the VM
    that we know about - the test that triggers this was admittedly buggy,
    but if the test was buggy it is quite possible that real uses are
    buggy too. We don't actually have any known case of any such real user
    breakage, but we do have a nice fix for the test regression that is
    very  much the RightThing(tm) to do in the long run, so that has been
    actively discussed.
    
    We know what the fix looks like, and a few initial patches have been
    floating around, but a final patch doesn't exist yet, and depending on
    how that goes this might be something that pushes out the final 5.9 by
    a week. We'll see.
    
    So there's still some development going on, but honestly, that VM case
    is a very odd corner case that normal users should never hit, so it
    should not keep anybody from testing this in the meantime.
    
    Holler if you see anything odd,

  • Linux 5.9-rc6 Released With Soft Scrollback Removed, Performance Regression Fixed

    The sixth weekly release candidate to Linux 5.9 is now available with at least two notable changes in particular. Prominent in Linux 5.9-rc6 is the fix for the previously reported performance regression hitting 5.9. In case you missed it from the end of last week, see the article on controlling page lock unfairness as part of addressing the performance regression. That code is now in Linux 5.9-rc6 and the performance is back on track with Linux 5.8 while I will have out more benchmark numbers soon on the revised Linux 5.8 vs. 5.9 performance state.

  • Fair Code vs Open Source, Which Wins The Future?

    When developers release their software as open source, they are also giving a by-definition right to every company in the world to commercially use their software without having to obtain a license or share some profits with them. And this caused some problems in the open source world few years ago. For example, Amazon took the MongoDB source code (An open source database system), changed its name and then provided it as a SaaS (Software-as-a-Service) on its AWS platform, and then charged people money to use it. MongoDB developers were angered since they literally got nothing back from Amazon although they are the original creators of 100% of the code. This adds some sustainability problems to open source projects, as anybody and any company can just take the code and then reuse it commercially without giving anything back to the original developers. The original developers may starve and the project may stop, and there would be no obligation by anyone to commercially pay them. Fair code initiative arose from this context; To prevent anyone from using the software commercially without contacting the original software authors first, making it under the umbrella of what’s known as source-available models.

  • How to Convert a Project to REUSE Compatible License Statements?

    This blog post provides a step-by-step example about how the conversion of a project to REUSE compatible license statements is done in practice. For my setup, I have a readily configured kdesrc-build environment. First, I get out the most recent source code if the project I want to convert. For this tutorial, I use KTurtle, which is a nice and small application from KDE Education with just about 200 files.

  • Best Python Data Science Libraries
  • John Cook: Descartes and Toolz

    I was looking recently at the Python module toolz, a collection of convenience functions. A lot of these functions don’t do that much. They don’t save you much code, but they do make your code more readable by making it more declarative. You may not realize need them until you see them. For example, there is a function partitionby that breaks up a sequence at the points where a given function’s value changes. I’m pretty sure that function would have improved some code I’ve written recently, making it more declarative than procedural, but I can’t remember what that was. Although I can’t think of my previous example, I can think of a new one, and that is Descartes’ rule of signs.

  • How big data forced the hunt for extraterrestrial intelligence to evolve

    Interest in SETI can be used to bring the public into science as well. A recent collaboration between the SETI Institute and the open-source software project GNU Radio aims to give people the opportunity to learn about radio engineering, digital signal processing, and radio astronomy. By purchasing a dongle for around $25, members of the public can digitize analog radio signals and process signals on their computers.        

  • Getting credit: Taking your place in a meritocracy

    Dealing with either of those incredibly frustrating situations without appearing petty is difficult. But getting credit for your ideas and work is critical in today's organizational environments, especially those that aspire to be well-functioning meritocracies. Promotions, bonuses, and other forms of recognition (such as the opportunity to lead the project you proposed) are all generally based on performance. If people don't know you contributed, you'll likely be continually overlooked.
