Canonical Assures Users 32-bit Apps Will Run on Ubuntu 19.10 and Future - Updated

Monday 24th of June 2019 03:00:00 PM
Due to recent escalations, Canonical updated their view on the removal of support for the i386 (32-bit) architecture for Ubuntu 19.10 and future releases to assure users 32-bit apps will still run on the Linux-based operating system.

Last week, Canonical announced that they will completely deprecate support for 32-bit (i386) hardware architectures in future Ubuntu Linux releases, starting with the upcoming Ubuntu 19.10 (Eoan Ermine) operating system, due for release later this fall on October 17th. However, the company mentioned the fact that while 32-bit support is going away, there will still be ways to run 32-bit apps on a 64-bit OS.

As Canonical didn't give more details on the matter at the time of the announcement, many users started complaining about how they will be able to run certain 32-bit apps and game... (read more)

Friday 21st of June 2019 02:18:00 PM
The Red Hat Enterprise Linux and CentOS Linux operating systems have received new Linux kernel security updates that are marked as important and address the recently disclosed TCP vulnerabilities affecting all GNU/Linux distributions.

The new Linux kernel security updates patch an integer overflow flaw (CVE-2019-11477) discovered by Jonathan Looney in Linux kernel's networking subsystem processed TCP Selective Acknowledgment (SACK) segments, which could allow a remote attacker to cause a so-called SACK Panic attack (denial of service) by sending malicious sequences of SACK segments on a TCP connection that has a small TCP MSS value.

"While processing SACK segments, the Linux kernel's socket buffer (SKB) data structure becomes fragmented," reads Red Hat's security advisory. "Each fragment is about TCP maximum segment size (MSS) byt... (read more)

Canonical Will Drop Support for 32-bit Architectures in Future Ubuntu Releases

Tuesday 18th of June 2019 08:21:00 PM
Canonical announced today that it finally decided to completely drop support for 32-bit (i386) hardware architectures in future releases of its popular Ubuntu Linux operating system.

Last year, during the development cycle of the Ubuntu 18.04 LTS (Bionic Beaver) operating system series, Canonical announced that they won't offer 32-bit installation images (ISOs), a trend that was shortly followed by all official Ubuntu Linux flavors with the Ubuntu 18.10 (Cosmic Cuttlefish) release. However, Ubuntu's 32-bit repositories were still available.

As Ubuntu 18.04 LTS (Bionic Beaver) will be supported for the next five years, Canonical disabled upgrades from Ubuntu 18.04 LTS to Ubuntu 18.10 for 32-bit systems to avoid leaving users on a short-lived release, and now, they announced that starting with the upcoming Ubuntu 19.10 (Eoan Ermine) release, support for 32-bit system will no longer be provided.

Microsoft Edge for Linux: A Browser the Software Giant “Would Like to Do”

Friday 14th of June 2019 07:36:00 AM
Microsoft announced in late 2018 that it’d switch Edge browser to the Chromium engine, the same one that’s being used by Google Chrome.

This decision technically allows Microsoft to convert Microsoft Edge from a Windows 10-exclusive browser to a cross-platform application.

The company has already confirmed Microsoft Edge would be released beyond Windows 10, and existing preview builds also allow the browser to be installed on macOS.

The migration to Chromium would technically allow the company to bring Edge to Linux as well, and given its efforts to get more involved in the open-source world, such a release wouldn’t be surprising at all.

Linux version possible in the long term

And after Microsoft suggested that it’s indeed considering a Linux version of Edge back in May at the Build developer conference, the Edge tea... (read more)

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.

    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.

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.
