OpenSSH 8.0 released

Filed under
Security
BSD

This release contains mitigation for a weakness in the scp(1) tool
and protocol (CVE-2019-6111): when copying files from a remote system
to a local directory, scp(1) did not verify that the filenames that
the server sent matched those requested by the client. This could
allow a hostile server to create or clobber unexpected local files
with attacker-controlled content.

This release adds client-side checking that the filenames sent from
the server match the command-line request,

The scp protocol is outdated, inflexible and not readily fixed. We
recommend the use of more modern protocols like sftp and rsync for
file transfer instead.

Ubuntu 19.04 comes refreshed with the Linux 5.0 kernel

Filed under

Ubuntu

The heart of the Linux desktop beats on with the latest release of Canonical's Ubuntu distribution: Ubuntu 19.04. But, in addition, the server version comes ready with the latest cloud and container tools.

Now, if you're using Ubuntu in production, you probably should stick with the Long Term Support Ubuntu 18.04. After all, it comes with ten years of support. But there's a lot of tempting goodness in Disco Dingo, Ubuntu 19.04's playful moniker.

Some theming fixes to arrive with Plasma 5.16

Filed under
KDE

One of the things which makes Plasma so attractive is the officially supported option to customize also the style, and that beyond colors and wallpaper, to allow users to personalize the look to their likes. And designers have picked up on that and did a good set of custom designs (store.kde.org lists at the time of writing 454 themes).

  • 9 Useful PDF Manipulation Tools

    Portable Document Format (PDF) is a file format created by Adobe Systems in 1993 for document exchange. The format includes a subset of the PostScript page description programming language, a font-embedding system, and a structural storage system.

    Over the years PDF has become an extremely important file format. If you want to create documents that can be viewed under all major operating systems, PDF is the ticket, as it maintains the overall look and feel of documents regardless of what platform they are viewed under.

    There is a large range of PDF-related software available with many different applications available that can both output to and open files. Many open source software save documents to this format such as LibreOffice and GIMP.

    The purpose of this Group Test is to highlight high quality small tools that are designed to manipulate PDF files. We are not considering PDF editors, PDF viewers, tools that add an OCR layer to PDF files here. This is because these categories are covered by other legendary Group Tests.

  • Blender short film, new license for Chef, ethics in open source, and more news

    Spring, the latest short film from Blender Animation Studio, premiered on April 4th. The press release on Blender.org describes Spring as "the story of a shepherd girl and her dog, who face ancient spirits in order to continue the cycle of life." The development version of Blender 2.80, as well as other open source tools, were used to create this animated short film. The character and asset files for the film are available from Blender Cloud, and tutorials, walkthroughs, and other instructional material are coming soon.

  • 6 alternatives to OpsGenie for managing monitoring alerts

    Now, if an issue comes up with any of this company's products, the response team should act before the customer (and company) experiences negative effects. There won’t be much of a problem if the response team is immediately there to jump on the issue, but in case they are not, someone from the response team should notify them in some way to reduce the diameter of functional or possible financial losses.

    Here's the problem. People are not able to notice and respond to issues all the time. If you send the response team an email or text message, there is a probability that no one on the team will see it before the issue causes significant financial loss. Also, the response team might already be receiving so many email alerts that even if they are available, they may find it difficult to spot the high-impact issues among the smaller ones. In this situation, you should send someone from the response team a distinct alert, such as making a phone call or messaging a pager. However, if you decide to call, you need to know who is actually available, otherwise you might have to call multiple people until you find the response team member who is ready to jump on a ringing phone at that very moment, which can take even longer if your call is at an odd time for their location.

    Instead, what you need is a tool that not only monitors your systems but also intelligently manages the alert process for the quickest results possible. A popular commercial option is OpsGenie, and in this article, we will talk about open source alternatives to this proprietary option.

Qt/KDE: KDE Plasma 5.16 Pre-Beta and Qt Creator 4.9.0

  • KDE Plasma 5.16 Pre-Beta Run Through

    In this video, we are having a look at the pre-Beta version of KDE Plasma 5.16. It still have a few bugs but it is expected.

  • Qt Creator 4.9.0 released with language support, QML support, profiling and much more

    Yesterday, the team behind Qt released the latest version, Qt Creator 4.9.0, a cross-platform software development framework for embedded and desktop applications. This release comes with programming language support, changes to UI, QML support and much more.

  • Qt Creator hits 4.9 with ever-growing language skills

    Qt Creator 4.9 has been released, extending support for the language server protocol and improving diagnostics for C++ developers.

    The language server protocol was added in version 4.8 but can now work with document outlines, find usages and – using code actions – lets the language server suggest fixes or refactoring actions at a specific place in a piece of code. The custom highlighting file parser, meanwhile, has been replaced with KSyntaxHighlighting – the library also used in KDE.

    Another slew of changes improve C++ support, with – amongst other things – an option to format code instead of only indenting it, a tooltip button for copying and ignoring diagnostics, and an option to synchronise ‘Include Hierarchy’ with the current document.

  • Qt Creator 4.9 uses KSyntaxHighlighting

    As you can read in the official Creator 4.9.0 release announcement, Qt Creator now uses the KSyntaxHighlighting Framework for providing the generic highlighting.

    This is a nice step for the wider adoption of this MIT licensed part of the KDE Frameworks.

    And this is not just an one-way consumption of our work.

    The framework got actively patches back that make it more usable for other consumers, too, like Kate ;=)

  • A Special Offer for SAP HANA on IBM Power Systems Early Adopters

    In my blog, “Is time running out for your SAP Linux support?”, I talked about SUSE Linux Enterprise Server for SAP Applications 11 SP4 soon reaching its March 31, 2019 end date for General Support. This date has passed. To maintain support you have a choice of either upgrading to a currently supported version or adding Long Term Service Pack Support (LTSS). But if you’re an early adopter of SAP HANA on IBM Power Systems, then it’s not just a matter of upgrading the Linux OS. You need to migrate your data from Big Endian to Little Endian format. Also, your data is still probably in an SAP HANA 1.0 database so you’ll also need to migrate to SAP HANA 2.0. All of this can take significant time and effort.

  • Leadership of OpenJDK 8 and OpenJDK 11 Transitions to Red Hat

    OpenJDK is an open source implementation of Java, one of the most widely-used programming languages for building enterprise-grade applications. In its role as steward of OpenJDK 8 and OpenJDK 11 update releases, Red Hat will work with the community to enable continued innovation in Java.

    Red Hat has been a member of the OpenJDK community since 2007 and is one of the largest contributors to the project. Red Hat’s long-time Java technical lead, Andrew Haley, was appointed as project lead for OpenJDK 8 and OpenJDK 11 in February 2019. He has been an active member of the OpenJDK governing board for seven years and, in this capacity, helps to guide the future direction of Java and OpenJDK.

    In addition to its work within individual OpenJDK communities, Red Hat leads the upstream development of Shenandoah, a high-performance garbage collector that is now part of OpenJDK 12.

ZFS Indications Have Us Already Eager For Ubuntu 19.10

Filed under
Ubuntu

While Ubuntu 19.04 isn't even coming out until tomorrow, the indications around Ubuntu desktop ZFS support and functionality likely debuting the next cycle has us already quite eager for the Ubuntu 19.10 release coming out in October.

We've been anxiously clamoring for more details on the Ubuntu desktop ZFS plans as part of their new desktop installer initiative and much more than simply offering ZFS On Linux (ZoL) that they've been doing through their archive in recent years. In order to get this support ready before next year's Ubuntu 20.04 Long Term Support release, they need to have the initial work ready for Ubuntu 19.10 to ensure sufficient testing pre-LTS cycle.

Emacs finally gets Unicode-11.0-ready

Filed under
GNU

Unicode 11.0 has come to Emacs 26.2, which – although not the most recent edition lets devs using GNU’s text editor – at least lets devs get more creative with scripts and emojis.

To reduce crashes, the new version includes a xft-ignore-color-fonts variable that in its standard setting will stop the editor loading colour fonts when using the X FreeType interface library. Setting it to nil will, however, let users access those fonts if needed.

The movemail program from the GNU Mailutils is now set to be the default of mail-source-movemail-program, meaning it will be used even if it couldn’t be found when the editor was built. Adding the absolute file name of another executable will let users work with this instead.

Do We Have More Kubernetes Distributions Than We Need?

Filed under
Server
OSS

Kubernetes itself—meaning the source code you can download from kubernetes.io—is not very useful on its own. Setting up a Kubernetes cluster using the source code would require you to compile the code and set up a server environment (or, in most cases, a cluster of servers) to host it, install it, configure it, set up tools to manage it and update it all on your own.

That’s a lot of work, and it’s not a realistic way for most people to use Kubernetes. That’s why a number of companies have created Kubernetes distributions. The distributions provide not just a preconfigured version of Kubernetes itself, but also other important tools for installing and working with Kubernetes. Many distributions also include host operating systems. Some even give you hosting infrastructure in the form of IaaS in a public cloud.

Kubernetes is not unique in spawning an ecosystem of distributions. The Linux kernel has done the same thing. So have other complex software platforms, inlcuding Spark, Hadoop and OpenStack.

I Can't Believe I'm Writing This Linux Article About Loving The Xfce Desktop Environment

Linux
Reviews

My Choose Linux co-host Joe Ressington swears by Xfce. He has no interest in eye candy. He simply wants to get his production work done. I also appreciate a distraction-free environment (like elementary OS), but I crave a bit of elegance and visuals that don't bore me.

Every time I looked at screenshots of Xfce, though -- even from the official website -- I was reminded of something from the days of Windows 2000. Grey. Archaic. Uninteresting. It struck me as as one of the few alternatives people with anemic PCs are forced to use. MATE is one of those alternatives, but it comes off as sharper and more modern despite also thriving on low-end hardware. Even if it is obsessed with the color green.
