Canonical Outs Major Linux Kernel Updates for All Supported Ubuntu Releases

Friday 16th of August 2019 01:57:00 PM
Canonical released major Linux kernel updates for all supported Ubuntu Linux operating system series to address dozens of security vulnerabilities affecting all supported architectures on desktop, server, and cloud.

Available for Ubuntu 19.04 (Disco Dingo), Ubuntu 18.04 LTS (Bionic Beaver), Ubuntu 16.04 LTS (Xenial Xerus), and Ubuntu 14.04 ESM (Trusty Tahr), the new Linux kernel security updates are here to patch more than 30 security vulnerabilities, including a heap buffer overflow discovered in the Marvell Wireless LAN device driver and a NULL pointer dereference discovered in the Near-field communication (NFC) implementation.

The security patch also addresses a use-after-free vulnerability discovered by Google Project Zero's Jann Horn in the Linux kernel when accessing LDT entries, as well as a race condition when performing core dumps. A flaw discovered by Andrei Vlad Lutas and Dan Lutas in x86 processors, which incorrectly handled SWAPGS instructions during s... (read more)

LibreOffice 6.3 Open-Source Office Suite Officially Released, Here's What's New

Thursday 8th of August 2019 10:14:00 AM
The Document Foundation released today the LibreOffice 6.3 open-source and cross-platform office suite for Linux, Mac, and Windows platforms.

The third major, feature-full update to the latest LibreOffice 6 office suite series, LibreOffice 6.3, comes exactly six months after the LibreOffice 6.2 release to add better performance, enhanced interoperability with proprietary document formats, as well as a set of new features and other improvements.

LibreOffice 6.3 comes with an important change for Linux users, namely that it doesn't ship with 32-bit binaries for Debian or Red Hat-based operating systems. The Document Foundation is comitted to support 3... (read more)

Ubuntu 19.10 to Support ZFS on Root as an Experimental Option in the Installer

Wednesday 7th of August 2019 01:43:00 PM
Canonical announced today that it plans to implement support for ZFS on root file system in the upcoming Ubuntu 19.10 (Eoan Ermine) operating system.

Ubuntu 19.10 (Eoan Ermine) will be the next major release of the popular Ubuntu Linux operating system, and also a testbed for Canonical to implement new features and see if they prove to be useful to the community for upcoming LTS (Long Term Support) releases, such as next year's Ubuntu 20.04 LTS.

One of these new features coming to the Ubuntu 19.10 release this fall is an experimental option implemented in the graphical installer to let users create a root file system formatted with the ZFS file system. But Canonical warns users that they should not use it on a production machine.

"As we want to have the dataset layout right and we know a file system is very crucial as it's responsible for all your data, we don't want to... (read more)

Microsoft Teams for Linux Could Soon Be a Real Thing

Wednesday 7th of August 2019 07:59:00 AM
Microsoft might launch a Linux version of Microsoft Teams at some point in the future, according to company engineers working on the project.

Microsoft Teams is already available on the most popular platforms out there, including Windows, macOS, Android, and iOS, and given the software giant’s push towards the Linux world, such a release perfectly aligns with its long-term plans.

A thread on UserVoice, Microsoft’s feedback platform, discusses the chances of getting a Linux version of Microsoft Teams, with the post having nearly 9,000 upvotes from users, as per a tweet from @unixterminal.

“My team has some users on Linux, and one benefit Slack has is a Linux client. Without a Linux client on Microsoft Teams, some orgs may have to turn away in favor of Slack, so everyone can participate without keeping a browser open all the time,” the original feature suggestion reads.

Collabora Brings VR Support to Linux Desktop Environments, Sponsored by Valve

Tuesday 30th of July 2019 04:34:00 PM
Collabora today announced a new open-source project that promises to enable Linux-based desktop environments and window managers to be aware of VR (virtual reality).

Sponsored by Valve, the xrdesktop project is developed by Collabora and designed to integrate into existing desktop environments like KDE and GNOME, making them running in virtual reality (VR) runtimes. It does that by rendering windows in 3D space, allowing users to manipulate them with VR controllers and headsets.

"This integration of xrdesktop into the window managers enables mirroring existing windows into XR and to synthesize desktop input through XR actions. xrdesktop can be run as a dedicated scene application, but it also features an overlay mode, where desktop windows are overlaid over any other running VR application," explains Collabora's Lubosz Sarnecki.

Linux 5.4 To Expose What's Keeping The System Awake Via Sysfs

The next Linux kernel version will expose the real-time sources of what's keeping the system awake via Sysfs compared to existing source information that previously was only available via DebugFS. With Linux 5.4, wakeup source statistics will now be exposed under /sys/class/wakeup/wakeup*/ for tracking wakeups, their counts, and related bits for profiling the system for power usage optimizations. Suspend-blocking wakeup sources have been available under DebugFS to be useful for bug reporting and analyzing battery consumption. This solidifies the work now under Sysfs with a stable ABI. In addition to the interfaces now stable in adding them to sysfs, it makes them more accessible compared to DebugFS often being restricted to root or other restrictions in place by different distribution kernels.

Programming Leftovers

  • Creating a Docker Swarm Stack with Terraform (Terrascript Python), Persistent Volumes and Dynamic HAProxy.

    Before someone blame me about why I am not using Kubernetes, AWS ECS, Mesos or anything but Swarm the answer is simple: Docker Swarm is an inexpensive and very simple thin orchestrator. Because of this it miss a lot of features that Kubernetes already implemented by default. Most of important data centers (Google, AWS, Azure, Oracle, IBM, Digital Ocean, etc) already implemented some sort of Kubernetes as a Service make it easy its adoption. However, docker swarm does not have any datacenter are implementing it and are creating some of structure ready to go as K8s has.

  • Python Filter()

    Python filter() function applies another function on a given iterable (List/String/Dictionary, etc.) to test which of its item to keep or discard. In simple words, it filters the ones that don’t pass the test and returns the rest as a filter object. The filter object is of the iterable type. It retains those elements which the function passed by returning True. We can also convert it to List or Tuple or other types using their factory functions. In this tutorial, you’ll learn how to use the filter() function with different types of sequences. Also, you can refer to the examples that we’ve added to bring clarity.

  • Sending HTML messages with Net::XMPP (Perl)

    This started with a very simple need: wanting to improve the notifications I’m receiving from various sources.

  • Excellent Free Books to Master Programming

    A quick search of the internet reveals a plethora of books for programmers. No one has time to read even a minuscule fraction of the available books. What you need is a curated list of programming books. Better than that. A curated list of free programming books. Free and open source books still have a cost — your time. And just because a book is free/open source doesn’t, itself, signify any great quality to the work. Hence the need for some recommendations for free books to help you learn C, C++, Java, Python, R, or whatever language takes your fancy. The books we’re recommending will help increase your technical skills and make you proficient in the language of your choice. And some of them even provide a little light relief on the way. Humor can be a great aid to learning.

Anime studio, Khara, is planning to use open-source Blender software

The open-source 3D creation software, Blender, will be picked up by the Japanese anime studio, Khara. It’ll begin partially using the software for its current development ‘EVANGELION:3.0+1.0’ but will make the full switch once that project is finished. The current project is expected to end in June next year, so after that point, its employees will start using Blender for the majority of their work. At the moment, Khara uses 3ds Max from Autodesk on a subscription basis; however, the company found that it had to reach out to small and medium-sized businesses for its projects. Due to the limitations of those companies, it’s harder for them to afford 3ds Max. By switching to Blender, Khara says it can work better with external firms. Read more
