Canonical has released new Linux kernel security updates for all supported Ubuntu Linux releases to address various security vulnarabilities.

Available for Ubuntu 19.04 (Disco Dingo), Ubuntu 18.10 (Cosmic Cuttlefish), Ubuntu 18.04 LTS (Bionic Beaver), and Ubuntu 16.04 LTS (Xenial Xerus), the new security patches are here to fix several issues affecting the Linux kernels of these releases, especially a security vulnerability (CVE-2019-11191) that only affects the i386 (32-bit) kernels of Ubuntu 18.10, Ubuntu 18.04 LTS, and Ubuntu 16.04 LTS, as Ubuntu 19.10 and Ubuntu 19.04 are not affected.

"Federico Manuel Bento discovered that the Linux kernel did not properly apply Address Space Layout Randomization (ASLR) in some situations for setuid a.out binaries. A local attacker could use this to improve the chances of exploiting an existing vulnerability in a setuid a.out binary. As a hardening ... (read more)

Linux Kernel 5.0 Reaches End of Life, Users Urged to Upgrade to Linux Kernel 5.1

Tuesday 4th of June 2019 01:10:00 PM
Linux kernel developer Greg Kroah-Hartman announced today that the Linux 5.0 kernel series reached end of life, urging users to upgrade to the most recent stable series.

Released two months ago, on March 4th, 2019, by Linus Torvalds, the Linux 5.0 kernel series was long anticipated by the Linux community, but it was only the version number that was a major thing, as Linux kernel 5.0 didn't brought any major changes, nor it was a long-term support release.

Linux kernel 5.0.21 was released today as the last maintenance update for the Linux 5.0 kernel series, which means that no further updates or security patches will be provided for it. Therefore, users are urged to upgrade to the latest Linux 5.1 kernel series as soon as possible.

Antergos Linux Has Been Discontinued, All Users Will Be Migrated to Arch Linux

Monday 27th of May 2019 02:03:00 PM
The development behind the Antergos Linux operating system announced the discontinuation of the project, as they decided to step down from developing this Arch Linux-based GNU/Linux distribution.

Created more than seven years ago by Alexandre Filgueira, Gustau Castells, and Dustin Falgout, Antergos Linux was first called Cinnarch as it aimed to be an unofficial Cinnamon flavor of the popular and powerful Arch Linux operating system. A year later, it was renamed from Cinnarch to Antergos, which is a Galician word meaning "to link the past with the present."

Antergos wanted to provide the Linux community with a modern, beautiful, and powerful computer operating system that is easy to install, configure, and use. Antergos Linux used its own graphical installer, as oppossed to Arch Linux, which still doesn't have a GUI installed, those making the installation harder for newcomers, those bringing Arch Linux to the masses.

Programming: Rust and Python Miscellany

  • 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.

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.

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.

Samsung Galaxy Note 10 now links up with Windows and Mac PCs via supercharged DeX app

And there’s a big bonus here in the form of being able to drag-and-drop files directly from your phone to your PC, and vice versa. So you could take a photo from your Note 10 and whip it onto the PC to tweak it up in a proper heavyweight image editor, for example. Furthermore, as XDA Developers observes, Linux on DeX is available via the DeX app, allowing you to create a container and run an Ubuntu Linux image, giving you even more flexibility and options here. It’s not clear what Samsung intends to do in terms of giving users with older Galaxy handsets backwards compatibility, but at the moment, this is strictly a Galaxy Note 10-only affair, as mentioned. Finally, it’s worth noting that the app does warn that your phone might get hot running the DeX application, although exactly how hot likely depends on what you’ve got the hardware doing, of course.
