Gentoo-Based Porteus Kiosk 4.7 Brings More Mitigations Against Spectre Flaws

Filed under
Gentoo

Powered by the long-term supported Linux 4.14.50 kernel, Porteus Kiosk 4.7.0 is the second release of the operating system in 2018 and comes five months after version 4.6 to introduce more mitigations against the Spectre security vulnerabilities, though the next-gen Spectre flaws require microcode firmware updates for Intel CPUs.

"Newly discovered "Spectre Next Generation" vulnerabilities require updated microcode from Intel which is not available yet. Please consider enabling automatic updates service for your kiosks to receive latest fixes and patches as soon as they become available," reads today's announcement.

Canonical Shifts Its Fiscal Year Ahead Of Likely IPO

Filed under
Ubuntu

You have likely heard by now about Ubuntu maker Canonical planning to do an initial public offering (IPO) at some point in the not too distant future to become a publicly-traded company. The latest sign of that is Canonical has now shifted its corporate calendar.

Rather than ending its accounting period now on 31 March of each year, Canonical is shifting that to align with the end of each calendar year (31 December). 31 March tends to be the end of fiscal years for UK-based organizations. This change may indicate a desire of Canonical to more likely list on one of the US-based stock exchanges rather than London, but others may have differing hypothesis over the change.

KDE/Qt: Qt 3D, Kube/Kolab, GSoC, and Atelier (3-D Printing)

Filed under
KDE
  • What a mesh!

    With all the advances being made in Qt 3D, we wanted to create some new examples showing some of what it can do. To get us started, we decided to use an existing learning framework, so we followed the open source Tower Defence course, which you can find at CGCookie. Being a game, it allows an interactive view of everything at work, which is very useful.

  • Last week in Kube

    Perhaps if Windows wasn’t such a PITA there would be more progress

  • GSoC 2018: Week 4 & 5

    The last 2 weeks were mainly dedicatd for reviews and testing and thanks to my mentors, I passed the first evaluation with good work till now. Some significant changes were made on discussion with my mentors during the last 2 weeks in the code and some new features.

  • Giving Atelier some Love

    I work for atelier together with Chris, Lays and Patrick for quite a while, but I was basically being the “guardian angel” of the project being invocked when anything happened or when they did not know how to proceed (are you a guardian angel of a project? we have many that need that)

    For instance I’v done the skeleton for the plugin system, the buildsystem and some of the modules in the interface, but nothing major as I really lacked the time and also lacked a printer.

Devuan GNU+Linux 2.0.0 "ASCII"

Filed under
OS
Reviews

When I am trying out a desktop distribution, what really tends to divide the field of Linux distributions in my mind is not whether the system uses MATE or Plasma, or whether the underlying package manager uses RPM or Deb files. What tends to leave a lasting impression with me is whether the desktop environment, its applications and controls feel like a cooperative, cohesive experience or like a jumble of individual tools that happen to be part of the same operating system. In my opinion Ubuntu running the Unity desktop and Linux Mint's Cinnamon desktop are good examples of the cohesive approach. The way openSUSE's administration tools work together provides another example. Like them or hate them, I think most people can see there is an overall design, a unifying vision, being explored with those distributions. I believe Devuan falls into the other category, presenting the user with a collection of utilities and features where some assembly is still required.

This comes across in little ways. For example, many distributions ship Mozilla's Firefox web browser and the Thunderbird e-mail client together as a set, and they generally complement each other. Devuan ships Firefox, but then its counterpart is the mutt console e-mail program which feels entirely out of place with the rest of the desktop software. The PulseAudio sound mixing utility is included, but its system tray companion is not present by default. Even the system installer, which switches back and forth between graphical windows and a text console, feels more like a collection of uncoordinated prompts rather than a unified program or script. Some people may like the mix-and-match approach, but I tend to prefer distributions where it feels like the parts are fitted together to create a unified experience.

What I found was that Devuan provided an experience where I had to stop and think about where items were or how I was going to use them rather than having the pieces seamlessly fit together. However, once I got the system set up in a way that was more to my liking, I appreciated the experience provided. Devuan offers a stable, flexible platform. Once I shaped the operating system a little, I found it to be fast, light and capable. Having a fairly large repository of software available along with Flatpak support provided a solid collection of applications on a conservative operating system foundation. It was a combination I liked.

In short, I think Devuan has some rough edges and setting it up was an unusually long and complex experience by Linux standards. I certainly wouldn't recommend Devuan to newcomers. However, a day or two into the experience, Devuan's stability and performance made it a worthwhile journey. I think Devuan may be a good alternative to people who like running Debian or other conservative distributions such as Slackware. I suspect I may soon be running Devuan's Raspberry Pi build on my home server where its lightweight nature will be welcome.

5 open source alternatives to Dropbox

Filed under
OSS

Dropbox is the 800-pound gorilla of filesharing applications. Even it's a massively popular tool, you may choose to use an alternative.

Maybe that's because you're dedicated to the open source way for all the good reasons, including security and freedom, or possibly you've been spooked by data breaches. Or perhaps the pricing plan doesn't work out in your favor for the amount of storage you actually need.

Fortunately, there are a variety of open source filesharing applications out there that give you more storage, security, and control over your data at a far lower price than Dropbox charges. How much lower? Try free, if you're a bit tech savvy and have a Linux server to use.

Debian GNU/Linux 8 "Jessie" Has Reached End of Security Support, Upgrade Now

Filed under
Debian

Released more than three years ago, on April 25, 2015, Debian GNU/Linux 8 "Jessie" is currently considered the "oldstable" Debian branch since the release of the Debian GNU/Linux 9 "Stretch" operating system series precisely a year ago, on June 17, 2017. As such, Debian GNU/Linux 8 "Jessie" has now reached end of life and will no longer receive regular security support beginning June 17, 2018.

Security support for Debian GNU/Linux 8 "Jessie" will be handed over to the Debian LTS team now that LTS (Long Term Support) support has ended for Debian GNU/Linux 7 "Wheezy" on May 31, 2018. Debian GNU/Linux 8 "Jessie" will start receiving additional support from the Debian LTS project starting today, but only for a limited number of packages and architectures like i386, amd64, armel, and armhf.

openSUSE Tumbleweed Is Now Powered by Linux Kernel 4.17, KDE Plasma 5.13 Landed

Filed under
KDE
SUSE

As of today, the openSUSE Tumbleweed rolling operating system is now powered by the latest and most advanced Linux 4.17 kernel series, which landed in the most recent snapshot released earlier.

Tumbleweed snapshot 20180615 was released today, June 17, 2018, and it comes only two days after snapshot 20180613, which added the Mesa 18.1.1 graphics stack and KDE Plasma 5.13 desktop environment, along with many components of the latest KDE Applications 18.04.2 software suite.

Today's snapshot 20180615 continued upgrading the KDE Applications software suite to version 18.04.2, but it also upgraded the kernel from Linux 4.16.12 to Linux 4.17.1. As such, OpenSuSE Tumbleweed is now officially powered by Linux kernel 4.17, so upgrading your installs as soon as possible would be a good idea.

  • Using Open Source Software in a SecDevOps Environment

    On 21 June 2018 the Open Source Software3 Institute is hosting a discussion that should be of high interest to enterprise technologists in the DC/Northern Virginia, Maryland area. From their invite:

    Come hear from our panelists about how the worlds of Open Source Software and the Secure Development / Operations (SecDevOps) intersect and strengthen one another. SecDevOps seeks to embed security in the development process as deeply as DevOps has done with operations, and Open Source Software is a major factor in Security, Development, and Operations.

  • TenFourFox FPR8b1 available

    TenFourFox Feature Parity Release 8 beta 1 is now available (downloads, release notes, hashes). There is much less in this release than I wanted because of a family member in the hospital and several technical roadblocks. Of note, I've officially abandoned CSS grid again after an extensive testing period due to the fact that we would need substantial work to get a functional implementation, and a partially functional implementation is worse than none at all (in the latter case, we simply gracefully degrade into block-level divs). I also was not able to finish the HTML input date picker implementation, though I've managed to still get a fair amount completed of it, and I'll keep working on that for FPR9. The good news is, once the date picker is done, the time picker will use nearly exactly the same internal plumbing and can just be patterned off it in the same way. Unlike Firefox's implementation, as I've previously mentioned our version uses native OS X controls instead of XUL, which also makes it faster. That said, it is a ghastly hack on the Cocoa widget side and required some tricky programming on 10.4 which will be the subject of a later blog post.

  • GNU dbm 1.15

    GDBM tries to detect inconsistencies in input database files as early as possible. When an inconcistency is detected, a helpful diagnostics is returned and the database is marked as needing recovery. From this moment on, any GDBM function trying to access the database will immediately return error code (instead of eventually segfaulting as previous versions did). In order to reconstruct the database and return it to healthy state, the gdbm_recover function should be used.

  • Five Supercomputers That Aren't Supercomputers

    A supercomputer, of course, isn't really a "computer." It's not one giant processor sitting atop an even larger motherboard. Instead, it's a network of thousands of computers tied together to form a single whole, dedicated to a singular set of tasks. They tend to be really fast, but according to the folks at the International Supercomputing Conference, speed is not a prerequisite for being a supercomputer.

    But speed does help them process tons of data quickly to help solve some of the world's most pressing problems. Summit, for example, is already booked for things such as cancer research; energy research, to model a fusion reactor and its magnetically confined plasma tohasten commercial development of fusion energy; and medical research using AI, centering around identifying patterns in the function and evolution of human proteins and cellular systems to increase understanding of Alzheimer’s, heart disease, or addiction, and to inform the drug discovery process.

Making GNOME Look Like Apple's Operating System

  • A macOS Mojave Inspired GTK Theme Appears
    A new GTK theme brings the luscious look of macOS Mojave to the Linux desktop. Not that you should be surprised; we’ve written before about how easy it is to make Ubuntu look like a Mac. But thanks to this new macOS Mojave inspired GTK theme that fact is truer, and more faithful, than ever.
  • Make Ubuntu Look Like macOS Mojave’s Dark Mode
    If you’re a Linux user who likes the look of the dark mode coming in macOS Mojave, you’re in luck: there’s a GTK theme just for you. The theme is available on Gnome-Look.org alongside several other macOS inspired themes. You’re looking for the one titled McOS-MJV-Dark-mode, but feel free to download more if you think you might want to switch it up later. Installing is a little tricky: you need to create a .themes directory in your home folder, then extract the folder in the downloaded archive into that folder. Next you need to install Gnome Tweaks in the Ubuntu Software Store, which you can use to change the theme. You can also use Gnome Tweaks to move the buttons to the left side of the window, where they belong. Fight me.

  • Linux Foundation Shifts Network Infrastructure to Kubernetes
    The Linux Networking Fund (LNF) is making significant progress toward embracing Kubernetes as a platform for delivering a range of networking services that are expected to be widely embraced by telecommunications carriers and cloud service providers (CSP). Arpit Joshipura, general manager of networking an orchestration for The Linux Foundation, says the latest Beijing release of the Open Networking Automation Platform (ONAP) contains several modules that have been ported to Kubernetes, with more to follow once the Casablanca release of ONAP is released.
  • A Platform Of A Certain Age And Respectability
    But seriously. The many rivals of the OS/400 platform and its follow-ons since that June 21, 1988, launch of the Application System/400 are now gone or not even on life support. We can all rattle them off, but the important ones that drove innovation for OS/400 and its children through to the current IBM i are DEC’s VMS for the VAX and Alpha systems, Hewlett Packard Enterprise’s MPE for the HP 3000 and HP-UX for the HP 9000s, and Sun Microsystems’ Solaris for the Sparc systems. You could throw in SCO Unix, Novell NetWare, and a slew of proprietary operating systems in Europe and Japan, and while you are at it, you should probably also include the IBM System/38’s CPF operating system and the IBM System/36’s SSP operating system. Even OS/2 and its PS/2 platform actually predate the AS/400 by 10 months – and they are long, long gone.

A look at Lutris – Open Gaming Platform for GNU/Linux

Lutris is quite the handy application I’ve discovered, that helps with organization and installation of games on GNU/Linux, even if they come from multiple sources. One of the project's goals is to support any game that runs on Linux regardless of whether it runs natively, through Wine, or other means. The main appeal of Lutris is that it provides an interface to manage all games installed on the machine regardless of source. While it is necessary to integrate the games in the application first, doing so is not super complicated. You may add local games right away by selecting them from the local system or visit the Lutris website to add games this way. Lutris simplifies nearly everything. Users can visit the list of support games on the Lutris website, choose to download and install the game (Note: If its a game that must be bought, you must own it first.) The website lists supported games and where you can acquire or download them. You can use filters on the site to display only free games, games of a genre, or use the built-in search to find games of interest quickly using it. Read more
