Qubes OS Security-Focused Operating System Now Supports Librem Linux Laptops

Filed under
OS
Security

Last year, Purism started shipping coreboot-enabled Librem laptops, and it received some interesting feedback from customers who bought them and attempted to install early release candidate images of the Qubes 4.0 operating system, reporting that the Qubes OS installer complained about IOMMU support.

Apparently, IOMMU support wasn't available in Intel's Skylake processors that powered Purism's Librem laptops, but it's supported by the coreboot firmware, formerly known as LinuxBIOS, so the company had to update its laptops to the latest coreboot release, which lets users install Qubes OS 4.0 without any warnings.

KDE: Hiding Neon LTS Edition and KMarkdownWebView 0.5.0

Filed under
KDE
  • Hiding Neon LTS Edition

    With the new Plasma LTS came an update to KDE neon LTS Edition and lots of people asking which edition to use and what the difference is.  This caused us to review the purpose of LTS and as a result we’ve just hidden LTS from the download page.  The only difference with the LTS edition is that it stays on Plasma’s LTS release but apps and libraries still get updates.  This doesn’t fit well with the main use cases of an LTS which is that it only gets bug fixes and no new features.  Further we test Neon LTS edition less than any other edition so it’s more likely we’ll miss some problem, which is the opposite of what most people would expect. There are distros whose release model fits better with the needs of Plasma LTS but the constant updates of Neon don’t fit too well.  We’ll keep the edition around and don’t expect to make any changes to the repositories or builds, they’re useful for devs testing Plasma LTS, but we’re not advertising it for download since it gives a different expectation of what to expect than fits into the release method of Neon.

  • KMarkdownWebView 0.5.0

    The KMarkdownWebView software is for the rendered display of Markdown documents, using web technologies. It implements a C++/Qt-based wrapper around a local webpage with a JavaScript library (“marked”) which creates HTML from the plain text in Markdown format passed in.

GNOME: GNOME Mobile and Shelved Wallpapers

  • Python for GNOME Mobile?

    As you may already know, Python is one of the hottest programming language out there, with thousand of job offerings, so makes sense, at least for me, to push this language as official one for GNOME Mobile applications.

    elementary OS is doing a good job on engagement new developers, while use Vala as its official language. For me, Vala is a good candidate for advanced/performance constrained Mobile applications.

  • Shelved Wallpapers

    GNOME 3.28 will release with another batch of new wallpapers that only a freaction of you will ever see. Apart from those I also made a few for different purposes that didn’t end up being used, but it would be a shame to keep shelved.

    So here’s a bit of isometric goodness I quite enjoy on my desktop, you might as well.

Security: Mageia, Tizen, Equifax, Apple

  • Spectra-Meltdown mitigation update

    Since we released 4.14.18 yesterday, we now are in pretty good shape with the mitigations, especially on x86_64. We now have bits in place for Spectre v1, v2 and Meltdown.

    Of course over the coming weeks/months there will be more follow-up fixes upstream to cover corner cases, missed fixes and improvements for all of this…

    And we still need Intel and AMD to release microcodes so hardware vendors can release updated BIOS/EFI firmwares and to the public so we can provide microcode updates in case of vendors not providing new BIOS/EFI firmwares.

  • Apple AirPod began smoking in ear, blew apart, says man

     

    Suddenly, he said, he noticed smoke. It was coming from the area of his right ear. More specifically, the smoke was being emitted from one of his AirPods.
     

    He says that he immediately put both AirPods on a piece of workout equipment and walked away. By the time he came back, the smoking AirPod appeared to have completely burst apart.

  • A Recap Of The Many Interesting Presentations At FOSDEM 2018

    Over the past week and a half we have highlighted many of the interesting presentations that took place at the annual Free Open-Source Developers' European Meeting (FOSDEM) in Brussels. Here's a look back if you are behind on your Phoronix reading.

  • WebRender newsletter #14
  • Restricting AppCache to Secure Contexts

    The Application Cache (AppCache) interface provides a caching mechanism that allows websites to run offline. Using this API, developers can specify resources that the browser should cache and make available to users offline. Unfortunately, AppCache has limitations in revalidating its cache, which allows attackers to trick the browser into never revalidate the cache by setting a manifest to a malformed cache file. Removing AppCache over HTTP connections removes the risk that users could see stale cached content that came from a malicious connection indefinitely.

    LSD was founded by Stefan Lesicnik in 2001. In the early days, the company focused on supporting basic Linux servers.

  • Qt 5.10.1 Ships With More Than 300 Bug Fixes

    The Qt Company has announced the availability of Qt 5.10.1, the first bug-fix release to Qt 5.10 that shipped back in December.

    In the approximately two months since Qt 5.10.0, today's point release has more than 300 bug fixes and around 1,400 changes in total over the previous release.

Kudos to Namib Linux for Making Arch Approachable

Filed under
Reviews

Namib is an ideal Linux distro for anyone who wants to ease into the Arch approach to computing.

Namib is a newcomer -- the third and current release (version 17.11) arrived late last year. However, it makes up for its lack of age by its performance. Namib makes Arch simple.

Surprisingly very user-friendly as well as compatible with older computers, Namib also is very stable.

Since Namib is based on the Arch philosophy, it uses rolling releases so you do not have to reinstall the entire operating system every time a major update occurs. The Pacman package manager handles new system components along with security and application updates automatically.

Namib is very up to date.

Getting started with the RStudio IDE

Filed under
Development

For as long as I can remember, I've been toying with numbers. As an undergraduate student in the late 1970s, I began taking statistics courses, learning ways to examine and analyze data to uncover some meaning.

Back then, I had a scientific calculator that made statistical calculations much easier than ever before. In the early '90s, as a graduate student in educational psychology working on t-tests, correlations, and ANOVA, I started doing my calculations by meticulously writing text files that were fed into an IBM mainframe. The mainframe was an improvement over my handheld calculator, but one minor spacing error rendered the whole process null and void, and the process was still somewhat tedious.

Gaming
  • Super Tony Land is a story-based platformer that will let you build your own awesome stories

    Super Tony Land [Official Site, Kickstarter] sounds like a platformer that I could enjoy, one that will enable you to make your own challenges, worlds and stories.

    The game will use a "block based programming language" allowing you to create some really wild stuff. Not just in the form of levels, but vehicles and all sorts of wacky creations.

  • pocketsprite game console is the open-source tamagotchi of 2018

    ...it’s open source. sure, you could in theory just turn on the pocketsprite wi-fi, connect your computer up to it, and download games via pocketsprite’s desktop interface, but where’s the challenge in that? if you understand a few youtube-tutorial’s-worth of hacking, you could upload whatever you want to this tiny emulator...

  • Rise of the Tomb Raider announced for Linux, port from Feral Interactive

    Many asked, now Feral Interactive have answered. Rise of the Tomb Raider [Steam] is officially on the way to Linux! What a fantastic way to start a Tuesday with news like this! It still amazes me to this day that Linux will have games like this, very happy with the news!

    Feral aren't saying exactly when it will arrive, but they had a tweet out that said "This Winter" which has since been deleted (Edit: replaced with this one). You can see the official confirmation on their official site which now says "This spring", so it could be here sometime between March and late June.

  • Feral Is Bringing Rise of the Tomb Raider To Linux

    Feral Interactive has announced today that they are porting Rise of the Tomb Raider to Linux.

    Rise of the Tomb Raider was released for Windows in January of 2016 as the latest in the Tomb Raider franchise. Now two years later the Linux port will be released in the months ahead. When Feral has asked the community about games coming to Linux, this title has repeatedly been brought up as a title many Linux gamers would like to see following the port of the 2013 Tomb Raider game.

Everything I know about open source I learned from SpaceX

You probably heard, but the private rocket company SpaceX did a thing last week. And while it was really cool to watch live video from a freakin' rocket on my pocket computer, that's not all there is to it. As I thought about the Falcon Heavy launch, I realized it contains a lot of lessons from my experience in open source projects.

GNOME: WebKit, Fleet Commander, Introducing deviced

  • On Compiling WebKit (now twice as fast!)
    Are you tired of waiting for ages to build large C++ projects like WebKit? Slow headers are generally the problem. Your C++ source code file #includes a few headers, all those headers #include more, and those headers #include more, and more, and more, and since it’s C++ a bunch of these headers contain lots of complex templates to slow down things even more. Not fun.
  • Fleet Commander is looking for a GSoC student to help us take over the world
    Fleet Commander has seen quite a lot of progress recently, of which I should blog about soon. For those unaware, Fleet Commander is an effort to make GNOME great for IT administrators in large deployments, allowing them to deploy desktop and application configuration profiles across hundreds of machines with ease through a web administration UI based on Cockpit. It is mostly implemented in Python.
  • Introducing deviced
    Over the past couple of weeks I’ve been heads down working on a new tool along with Patrick Griffis. The purpose of this tool is to make it easier to integrate IDEs and other tooling with GNU-based gadgets like phones, tablets, infotainment, and IoT devices. Years ago I was working on a GNOME-based home router with davidz which sadly we never finished. One thing that was obvious to me in that moment of time was that I’m not doing another large scale project until I had better tooling. That is Builder’s genesis, and device integration is what will make it truly useful to myself and others who love playing with GNU-friendly gadgets.

KDE: Usability & Productivity, AtCore , Krita

To hold our hardware is the standard touch screen enclosure that often comes with the screen if you buy it in a kit.
  • Look, new presets! Another Krita 4 development build!
    We’ve been focusing like crazy on the Krita 4 release. We managed to close some 150 bugs in the past month, and Krita 4 is getting stable enough for many people to use day in, day out. There’s still more to be done, of course! So we’ll continue fixing issues and applying polish for at least another four weeks. One of the things we’re doing as well is redesigning the set of default brush presets and brush tips that come with Krita. Brush tips are the little images one can paint with, and brush presets are the brushes you can select in the brush palette or brush popup. The combination of a tip, some settings and a smart bit of coding! Our old set was fine, but it was based on David Revoy‘s earliest Krita brush bundles, and for Krita 4 we are revamping the entire set. We’ve added many new options to the brushes since then! So, many artists are working together to create a good-looking, useful and interesting brushes for Krita 4.

Software: GIMP, Spyder, SMPlayer

  • Five free photo and video editing tools that could save burning a hole in your pocket and take your creativity to the next level
    GIMP stands for the Gnu Image Manipulation Program and is the first word that people usually think about when it comes to free image editors. It’s a raster graphics editor, available on multiple platforms on PC. It has a similar interface to Photoshop: you have your tools on one side, there’s an option for your tool window and then you have your layers window on another side. Perhaps one of the most useful features of GIMP is the option of plugins. There is a wide database for them and there’s a plugin for almost any task you might need to carry out. GIMP is extremely extensive, and it’s the choice of the FOSS community, thanks to the fact that it’s also open source. However, there are also some disadvantages. For example, GIMP has no direct RAW support yet (you have to install a plugin to enable it, which means a split workflow). It also has quite a bit of a learning curve as compared to Photoshop or Lightroom.
  • Introducing Spyder, the Scientific PYthon Development EnviRonment
    If you want to use Anaconda for science projects, one of the first things to consider is the spyder package, which is included in the basic Anaconda installation. Spyder is short for Scientific PYthon Development EnviRonment. Think of it as an IDE for scientific programming within Python.
  • SMPlayer 18.2.2 Released, Install In Ubuntu/Linux Mint Via PPA
    SMPlayer is a free media player created for Linux and Windows, it was released under GNU General Public License. Unlike other players it doesn't require you to install codecs to play something because it carries its own all required codecs with itself. This is the first release which now support MPV and some other features such as MPRIS v2 Support, new theme, 3D stereo filter and more. It uses the award-winning MPlayer as playback engine which is capable of playing almost all known video and audio formats (avi, mkv, wmv, mp4, mpeg... see list).
