Q4OS Operating System Brings the Trinity Desktop to Debian GNU/Linux 10 "Buster"

Sunday 28th of July 2019 06:58:00 PM
The Q4OS team announced the released of the Q4OS 3.8 "Centaurus" Linux and Debian-based computer operating system, a major version that adds many new features and improvements.

Based on the recently released Debian GNU/Linux 10 "Buster" operating system series, Q4OS 3.8 "Centaurus" comes more than seven months after the Q4OS 2.7 "Scorpion" release and it is the first stable version in the 3.x series, which was in heavy development during the last few years.

For a long time, Q4OS was shipping with the Trinity Desktop Environment (TDE) by default, which offers users, especially those who want to switch from Windows to Linux, a very familiar interface. However, it looks like the Q4OS 3.8 "Centaurus" series uses the latest stable KDE Plasma desktop by default.

"One of the Q4OS specific goals is the ability to have Plasma and Trinity desktop alongside each other installed," explain the developers. "Plasma is being... (read more)

GNU Linux-Libre 5.2 Kernel Released for Those Seeking 100% Freedom for Their PCs

Tuesday 9th of July 2019 04:16:00 PM
The GNU Linux-libre project has released the GNU Linux-libre 5.2 kernel, a 100% free version of the Linux kernel that doesn't include any proprietary drivers, firmware, or code.

Based on the recently released Linux 5.2 kernel series, which introduces the Sound Open Firmware support for DSP audio devices, the GNU Linux-libre 5.2 kernel also ships with the open-source firmware, which wasn't included in previous versions of the GNU Linux-libre kernel because they were overlooked.

"I had not realized the SOF files were Free Software in recent earlier releases, so the requests for these files were disabled in them," said developer Alexandre Oliva in a mailing list announcement. "Only while cleaning up the new kernel module specifically devoted to SOF-supporting devices did I realize my mistake."

The GNU Linux-libre 5.2 kernel also deblobs several new drivers, including btmtksdio, iqs5xx, is... (read more)

  • This Week in Rust 300
  • Python String Interpolation with the Percent (%) Operator

    There are a number of different ways to format strings in Python, one of which is done using the % operator, which is known as the string formatting (or interpolation) operator. In this article we'll show you how to use this operator to construct strings with a template string and variables containing your data.

  • Your Guide to the CPython Source Code

    Are there certain parts of Python that just seem magic? Like how are dictionaries so much faster than looping over a list to find an item. How does a generator remember the state of the variables each time it yields a value and why do you never have to allocate memory like other languages? It turns out, CPython, the most popular Python runtime is written in human-readable C and Python code. This tutorial will walk you through the CPython source code. You’ll cover all the concepts behind the internals of CPython, how they work and visual explanations as you go.

  • Python 3.8 support in PyCharm

    The release of Python 3.8 brought new features to the Python coding realm. The language is evolving according to its community’s needs by addressing cases where new syntax or logic become necessary. From new ways of assigning expressions to restriction of usage of function declarations, calls, and variable assignations, this latest release presents new options to code. Of course, PyCharm couldn’t get behind, so we now support some of the major features coming with this new version. This article will walk you through the features currently supported by our latest PyCharm release. To try them out, get the latest version of PyCharm and download the current beta release of Python 3.8 from here. From there you will just need to switch to Python 3.8 as your interpreter in PyCharm (if you’re not sure how to switch the interpreter, jump into our documentation for help).

  • Python Arrays in a Nutshell

    Python arrays are homogenous data structure. They are used to store multiple items but allow only the same type of data. They are available in Python by importing the array module. Lists, a built-in type in Python, are also capable of storing multiple values. But they are different from arrays because they are not bound to any specific type. So, to summarize, arrays are not fundamental type, but lists are internal to Python. An array accepts values of one kind while lists are independent of the data type.

    I’m thrilled to share this update with you today. Bryce and Brady have joined us last week and will be able to help out on Support for some of the new efforts Mozilla are working on towards creating a connected and integrated Firefox experience. They are going to be involved with new products, but also they won’t forget to put extra effort in providing support on forums and as well as serving as an escalation point for hard to solve issues.

  • FPR16 delays

    FPR16 was supposed to reach you in beta sometime tomorrow but I found a reproducible crash in the optimized build, probably due to one of my vain attempts to fix JavaScript bugs. I'm still investigating exactly which change(s) were responsible. We should still make the deadline (September 3) to be concurrent with the 60.9/68.1 ESRs, but there will not be much of a beta testing period and I don't anticipate it being available until probably at least Friday or Saturday. More later.

Games: Loria, Dota Underlords and Steam in China

  • Classic inspired RTS Loria is now available DRM-free on GOG

    If you're like me and you enjoy a good real-time strategy game, Loria is actually pretty good. It added Linux support on Steam earlier this year and now it's also available on GOG. While it's inspired by titles like Warcraft II, it's not just a retro RTS. There's a few RPG-like elements including hero units, item collection, quests and more.

  • The Underlords are actually coming to Dota Underlords, plus a new Duos mode

    Valve continue to push out changes rapidly to their auto-battler Dota Underlords, with some of their upcoming plans now being detailed in a fresh update. One big new feature planned to be available in a few weeks is a new Duos game mode. Valve say it's a new way to play cooperatively with a friend. You party up and battle against other teams and it will support both Casual and Ranked play. The actual Underlords are going to be making an appearance soon too. This feature Valve said they're "excited" about, as they're a "core part of the game". They haven't said how they will work but they will "add a layer of fun and strategy to every match" so I'm very curious to see what happens.
