The Samsung Developer Conference, held this week in San Francisco, brings creators together to discover and learn about the latest technologies in Samsung’s portfolio and further afield. One of the technologies showcased, following the initial demo in 2017, is Samsung’s Linux on DeX. Samsung DeX, launched last year, lets users of Samsung flagship Galaxy devices enjoy apps on a bigger screen for a better viewing experience, whether watching films, playing games or just browsing the web.

This year, Samsung is announcing the beta launch of Linux on DeX which extends the value of Samsung DeX to Linux developers. Linux on DeX empowers developers to build apps within a Linux development environment by connecting their Galaxy device to a larger screen for a PC-like experience.

Got a Screwdriver? GalliumOS Can Turn Chromebooks Into Linux Boxes

GalliumOS is a Chromebook-specific Linux variant. It lets you put a real Linux distro on a Chromebook.

My recent review of a new Chromebook feature -- the ability to run Linux apps on some Chromebook models -- sparked my interest in other technologies that run complete Linux distros on some Chromebooks without using ChromeOS.

GalliumOS is not a perfect solution. It requires making a physical adjustment inside the hardware and flashing new firmware before the GalliumOS installation ISO will boot. However, it can be a handy workaround if your Chromebook does not support Linux apps and/or Android apps.

If you follow directions explicitly and can wield a screwdriver to remove the bottom panel, GalliumOS is an ingenious Linux distro that can give you the best of two computing worlds. You can install it as a fully functional replacement for the ChromeOS on a compatible Chromebook. You can install it as a dual boot to give you both ChromeOS and a complete Linux distro on one lightweight portable computer.

How To Install Kali Linux Tools In Ubuntu

Filed under
Linux

Today I am going to do a quick demonstration of how to easily install a suite of security testing tools from Kali Linux onto a Ubuntu machine. For a bit of background information, Kali Linux is a distribution derived from Debian. Its sole purpose is to provide a suite of tools for penetration testing (pentesting) and forensics. It is provided by Offensive Security, an organization dedicated to providing security training. There is a very long list of tools available for Kali. Such tools include (but are not limited to) forensics, vulnerability checks, access checks, and stress testing.

LWN Kernel Articles: 4.20/5.0 Merge, Jiri Kosina, Arnd Bergmann and Greg Kroah-Hartman

Filed under
Linux
  • 4.20/5.0 Merge window part 1

    Linus Torvalds has returned as the keeper of the mainline kernel repository, and the merge window for the next release which, depending on his mood, could be called either 4.20 or 5.0, is well underway. As of this writing, 5,735 non-merge changesets have been pulled for this release; experience suggests that we are thus at roughly the halfway point.

  • Improving the handling of embargoed hardware-security bugs

    Jiri Kosina kicked off a session on hardware vulnerabilities at the 2018 Kernel Maintainers Summit by noting that there are few complaints about how the kernel community deals with security issues in general. That does not hold for Meltdown and Spectre which, he said, had been "completely mishandled". The subsequent handling of the L1TF vulnerability suggests that some lessons have been learned, but there is still plenty of room for improvement in how hardware vulnerabilities are handled in general.

    There are a number of reasons why the handling of Meltdown and Spectre went bad, he said, starting with the fact that the hardware vendors simply did not know how to do it right. They didn't think that the normal security contact (security@kernel.org) could be used, since there was no non-disclosure agreement (NDA) in place there. Perhaps what is needed is the creation of such an agreement or, as was discussed in September, a "gentleman's agreement" that would serve the same role.

  • Removing support for old hardware from the kernel

    The kernel supports a wide range of hardware. Or, at least, the kernel contains drivers for a lot of hardware, but the hardware for which many of those drivers was written is old and, perhaps, no longer in actual use. Some of those drivers would certainly no longer work even if the hardware could be found. These drivers provide no value, but they are still an ongoing maintenance burden; it would be better to simply remove them from the kernel. But identifying which drivers can go is not as easy as one might think. Arnd Bergmann led an inconclusive session on this topic at the 2018 Kernel Maintainers Summit.

    Bergmann started by noting (to applause) that he recently removed support for eight processor architectures from the kernel. It was, he said, a lot of work to track down the right people to talk to before removing that code. In almost every case, the outgoing architectures were replaced — by their creators — by Arm-based systems. There probably are not any more architectures that can go anytime soon; Thomas Gleixner's suggestion that x86 should be next failed to win the support of the group.

  • The proper use of EXPORT_SYMBOL_GPL()

    The kernel, in theory, puts strict limits on which functions and data structures are available to loadable kernel modules; only those that have been explicitly exported with EXPORT_SYMBOL() or EXPORT_SYMBOL_GPL() are accessible. In the case of EXPORT_SYMBOL_GPL(), only modules that declare a GPL-compatible license will be able to see the symbol. There have been questions about when EXPORT_SYMBOL_GPL() should be used for almost as long as it has existed. The latest attempt to answer those questions was a session run by Greg Kroah-Hartman at the 2018 Kernel Maintainers Summit; that session offered little in the way of general guidance, but it did address one specific case.

  • Blockchain as a Catalyst for Good

    Blockchain and its ability to “embed trust” can help elevate trust, which right now, is low, according to Sally Eaves, a chief technology officer and strategic advisor to the Forbes Technology Council, speaking at The Linux Foundation’s Open FinTech Forum in New York City.

    People’s trust in business, media, government and non-government organizations (NGOs) is at a 17-year low, and businesses are suffering as a result, Eaves said.

Choosing a printer for Linux

Filed under
Linux

We've made significant strides toward the long-rumored paperless society, but we still need to print hard copies of documents from time to time. If you're a Linux user and have a printer without a Linux installation disk or you're in the market for a new device, you're in luck. That's because most Linux distributions (as well as MacOS) use the Common Unix Printing System (CUPS), which contains drivers for most printers available today. This means Linux offers much wider support than Windows for printers.

    Of course, Dropbox does see this differently, but their explanation that ext4 is the only reasonable file system (and be aware, not in all combination and encryption), and also the only that supports extended attributes, is so ridiculously stupid that it is vain to even discuss it.

    Yes I know, as OSS enthusiast I should (and I am) using NextCloud. But integration-wise Dropbox is still the best, and many of my applications only offer Dropbox integration (or, God forbid, OneDrive integration).

This brings native Linux app functionality to the Chromebooks with the MT8173C chipset and although the number of devices is few, MediaTek Chromebooks are relatively inexpensive and versatile machines.

  • Some Chromebooks Won’t Get Linux Apps. Here’s What You Can Do Instead

    When Chromebooks first began getting support for Android apps, there was some confusion as to just which Chromebooks would be supported. The same thing is starting to play out—though to a lesser degree—with support for Linux apps.

    You’ve always been able to install Linux applications (or other Linux-based operating systems) on Chromebooks through a workaround called Crouton because Chrome OS is based on the Linux kernel. The new method for installing Linux apps is much easier than before since it’s a baked-in part of the operating system.

    But not all Chromebooks will get official support for Linux apps. Here’s the deal.

    In October 2018, Microsoft had release a cumulative update KB4462933 for Windows 10 V1803 users who had installed Windows 10 April 2018 update. This cumulative update released on 24th October lifted Windows 10 V1803 to build 17134376. It was a massive update with several important improvements and fixes. However, there were two main issues with this update that no one had noticed before, BornCity reports. One of the issues is the dysfunctional behavior of Edge Developer Tools and another is problems with SQL connections. These issues were also acknowledged by Microsoft on its support page for this update.

    According to WindowsLatest, Microsoft had not originally acknowledged the presence of these issues but later quietly updated the document to confirm these two issues being faced with the latest update.

Mozilla Firefox and Google Chrome: Net Neutrality Stance, Mozilla, a VR Work, Firefox Monitor and 5 Best Chrome Extensions For Productivity

  • Mozilla Fights On For Net Neutrality
    Mozilla took the next step today in the fight to defend the web and consumers from the FCC’s attack on an open internet. Together with other petitioners, Mozilla filed our reply brief in our case challenging the FCC’s elimination of critical net neutrality protections that require internet providers to treat all online traffic equally. The fight for net neutrality, while not a new one, is an important one. We filed this case because we believe that the internet works best when people control for themselves what they see and do online. The FCC’s removal of net neutrality rules is not only bad for consumers, it is also unlawful. The protections in place were the product of years of deliberation and careful fact-finding that proved the need to protect consumers, who often have little or no choice of internet provider. The FCC is simply not permitted to arbitrarily change its mind about those protections based on little or no evidence. It is also not permitted to ignore its duty to promote competition and protect the public interest. And yet, the FCC’s dismantling of the net neutrality rules unlawfully removes long standing rules that have ensured the internet provides a voice for everyone. Meanwhile, the FCC’s defenses of its actions and the supporting arguments of large cable and telco company ISPs, who have come to the FCC’s aid, are misguided at best. They mischaracterize the internet’s technical structure as well as the FCC’s mandate to advance internet access, and they ignore clear evidence that there is little competition among ISPs. They repeatedly contradict themselves and have even introduced new justifications not outlined in the FCC’s original decision to repeal net neutrality protections.

VR is changing the very future of web interaction, so advancing it is crucial to Mozilla’s mission. That was the initial idea behind Hubs by Mozilla, a VR interaction platform launched in April 2018 that lets you meet and talk to your friends, colleagues, partners, and customers in a shared 360-environment using just a browser, on any device from head-mounted displays like HTC Vive to 2D devices like laptops and mobile phones. Since then, the Mozilla VR team has kept integrating new and exciting features to the Hubs experience: the ability bring videos, images, documents, and even 3D models into Hubs by simply pasting a link. In early October, two more useful features were added: drawing and photo uploads.

Graphics: Open-Source AMD Linux Driver Stack, Mesa 18.3.0 RC, ROCm 1.9.2 and Firefox on Wayland

  • The Open-Source AMD Linux Driver Stack Hitting Problems With The Radeon RX 590
    While the Radeon RX 590 that launched this week is just yet another Polaris refresh, it turns out the open-source AMD Linux graphics driver stack isn't yet playing well with retail RX 590 graphics cards. This is quite a surprise considering the PCI ID was picked up months ago and the mature Polaris Linux driver support for quite a while now, but could be like the rough Raven Ridge Linux experience where the production cards with the shipping vBIOS isn't what the developers encountered during their pre-production driver enablement. [...] Long story short, it looks like at least one initialization issue is blocking the Radeon RX 590 Linux support. Hopefully the workaround ends up being trivial enough that it can be quickly back-ported to existing stable Linux kernel series. Once the Radeon RX 590 is running well on Linux, I'll be through with a ton of benchmarks that I have already been working on this week with other graphics cards using the newest Linux driver stacks. This situation is sadly reminiscent of the Raven Ridge launch earlier this year where the open-source driver team was working on support for months in advance, but the production hardware/BIOS ended up varying a lot from their hardware bring-up that is was very shaky support at launch. The Raven Ridge support improved a lot on Linux since launch, but even to this day some hardware still seems to be problematic both of hardware in my labs as well as reports by users. Hopefully it won't take nearly as long for the RX 590 support to be in shape.

  • Delver devs release their tech publicly under open source license
    As an added bonus, it's always nice when developers open source their tech to share with others. The source release doesn't contain or cover the game data from Delver, and the game data remains subject to original copyright and applicable law. It's also worth mentioning that the source code release is licensed under the GNU General Public License v2.0, meaning the software can continue to be shared, edited, and distributed for free, and can be used for commercial use as well.

One way to look at Amazon's struggles is through the lens of "proprietary software creates lock-in," but this isn't actually helpful. Why? Because open source creates similar lock-in, and that's something open source entrepreneurs might want to consider.

I think less than 10% of the world had internet. I started Drupal; it was very much an experimental platform for me, just to have some fun. I was fascinated with the web, and I didn't have any grand plans. Obviously, that changed over time. I made it open source, [and] it started growing, slowly. Drupal started to grow, so I started my plans for Drupal and [followed] my conviction of us being onto something. We made a bet-the-farm bet on cloud [in about 2008], and that turned out to be the right bet, because we pioneered a new business model for open source, delivering [it] in the cloud. And a lot of companies are doing that now -- Elastic Path, MongoDB -- and I'm very proud of that.
  • Openstack moves one step closer to the edge
    The second Openstack Summit of the year drew to a close in Berlin yesterday, and it will be the last of its name as it rebrands as the Open Infrastructure Summit in 2019, a move that seems largely in line with the evolution of the open source cloud platform as it shifts further into edge and builds out a series of related pilot projects with Openstack as the core proposition. Many of the keynotes this time around showed the progress that the community had made in building out the pilot projects announced at the Vancouver Summit earlier this year. One in particular, the first release of StarlingX, might well help cement the open infrastructure platform in edge. StarlingX is branded as an open source edge platform, with telecom and IoT use cases in mind. According to the Foundation it "leverages components of Ceph, Openstack and Kubernetes and complements them with new services including configuration and fault management", in particular to address technology challenges around high availability and ultra-low latency compute.
