  • Tuning your Intel Graphics Card in Ubuntu 18.04

    In the computing world things move at a brisk pace. To appeal to business users and conservative types like me Ubuntu releases the Long Term Support (LTS) versions of Ubuntu the latest of which is Ubuntu 18.04 which came out early this year. Ubuntu 16.04 for which I wrote the guide, is the LTS version prior to 18.04.

    It’s a little bit late to say this now but Ubuntu 18.04 came with a lot of changes including the infamous switchback to GNOME and the subsequent death of Unity. Another not so famous change was the fact that Intel drivers now ship with the kernel. This is not an Ubuntu specific change per se which explains why it was more of a footnote and not a headline in the Ubuntu world.

  • 4 Best open source & free YouTube Downloader for Ubuntu Linux

    Downloading YouTube Videos on Ubuntu Linux is not that much difficult as it appears. Lots of newbies think that Windows is the only platform to download online Youtube videos due to the availability of tons of free YouTube downloader software for it. However, after going through this article their opinion would be changed forever because not only normal videos but 4K videos can be downloaded on the Linux platforms as easy as on Windows.

Mark Shuttleworth delivered an unashamed plug for Ubuntu while cheerfully throwing a little shade on the competition at the OpenStack Berlin 2018 summit last week.

If Nick Barcet of Red Hat had elicited gasps by suggesting the OpenStack Foundation (OSF) might consider releasing updates a bit more frequently, Shuttleworth sent eyebrows skywards by announcing that the latest Long Term Support (LTS) edition of Ubuntu, 18.04, would get 10 years of support.

Ubuntu

If you are/were a fan of Ubuntu's Unity desktop environment, Unite-Shell is one of the most promising efforts to date for making the current GNOME 3 stack more like Unity.

The Unite Shell is an extension to GNOME Shell for configuring it to look just like Ubuntu's Unity 7. While it made waves a bit earlier this month, a Phoronix reader reported in over the weekend just how good it looks and works that it's worthy of an extra shout-out.

Is Linux IoT a potential big new market for EUC vendors?

Filed under
Linux

One thing we’re seeing now is how Linux for IoT is clearly a big trend, with several well-known vendors developing Linux IoT operating systems. A 2018 survey from earlier this year found that it dominates IoT, with about 72% using Linux-based OSes.

This could have an effect on players big and small in our space, so let’s take a look at what’s going on.

7 command-line tools for writers

Filed under
OSS

For most people (especially non-techies), the act of writing means tapping out words using LibreOffice Writer or another GUI word processing application. But there are many other options available to help anyone communicate their message in writing, especially for the growing number of writers embracing plaintext.

There's also room in a GUI writer's world for command line tools that can help them write, check their writing, and more—regardless of whether they're banging out an article, blog post, or story; writing a README; or prepping technical documentation.

Stumbling into Linux and open source from Vietnam to Amsterdam

Filed under
Linux
OSS

Since the beginning of time... no, really, just the beginning of Opensource.com in 2010, our writers have shared personal stories of how they got into open source or Linux (many times both).

Some had friends in school remark "You don't know Linux? What's going on with you, dude?" Some came in through the gateway of gaming, and others were simply looking for alternatives.

When I came on the scene in 2012 as a newcomer to open source and Linux, I saw these stories as pure gold. They get to the heart of why people are so passionate about it and why they love talking about it with other people who "get it." Now I'm one of those people, too.

Review: NetBSD 8.0

Filed under
Reviews
BSD

NetBSD, like its close cousins (FreeBSD and OpenBSD) does not do a lot of hand holding or automation. It offers a foundation that will run on most CPUs and we can choose to build on that foundation. I mention this because, on its own, NetBSD does not do much. If we want to get something out of it, we need to be willing to build on its foundation - we need a project. This is important to keep in mind as I think going into NetBSD and thinking, "Oh I'll just explore around and expand on this as I go," will likely lead to disappointment. I recommend figuring out what you want to do before installing NetBSD and making sure the required tools are available in the operating system's repositories.

Some of the projects I embarked on this week (using ZFS and setting up file sharing) worked well. Others, like getting multimedia support and a full-featured desktop, did not. Given more time, I'm sure I could find a suitable desktop to install (along with the required documentation to get it and its services running), or customize one based on one of the available window managers. However, any full featured desktop is going to require some manual work. Media support was not great. The right players and codecs were there, but I was not able to get audio to play smoothly.

My main complaint with NetBSD relates to my struggle to get some features working to my satisfaction: the documentation is scattered. There are four different sections of the project's website for documentation (FAQs, The Guide, manual pages and the wiki). Whatever we are looking for is likely to be in one of those, but which one? Or, just as likely, the tutorial we want is not there, but is on a forum or blog somewhere. I found that the documentation provided was often thin, more of a quick reference to remind people how something works rather than a full explanation.

As an example, I found a couple of documents relating to setting up a firewall. One dealt with networking NetBSD on a LAN, another explored IPv6 support, but neither gave an overview on syntax or a basic guide to blocking all but one or two ports. It seemed like that information should already be known, or picked up elsewhere.

Newcomers are likely to be a bit confused by software management guides for the same reason. Some pages refer to using a tool called pkg_add, others use pkgsrc and its make utility, others mention pkgin. Ultimately, these tools each give approximately the same result, but work differently and yet are mentioned almost interchangeably. I have used NetBSD before a few times and could stumble through these guides, but new users are likely to come away confused.

One quirk of NetBSD, which may be a security feature or an inconvenience, depending on one's point of view, is super user programs are not included in regular users' paths. This means we need to change our path if we want to be able to run programs typically used by root. For example, shutdown and mount are not in regular users' paths by default. This made checking some things tricky for me.

Ultimately though, NetBSD is not famous for its convenience or features so much as its flexibility. The operating system will run on virtually any processor and should work almost identically across multiple platforms. That gives NetBSD users a good deal of consistency across a range of hardware and the chance to experiment with a member of the Unix family on hardware that might not be compatible with Linux or the other BSDs.

  • Researchers Find Critical Vulnerability In Optical In-Display Fingerprint Sensors, Allowed Attackers To Unlock Devices Instantly

    In-Display Fingerprint sensors seem like an upcoming trend in smartphones. Conventional fingerprint sensors have become quite reliable over the years, but it’s still limited by design. With conventional fingerprint sensors, you need to locate the sensor and then unlock your phone. With the scanner placed under the display, unlocking the device feels much more natural. The technology is still in its infancy and hasn’t really matured yet, but a few companies like OnePlus have already put out phones with In-Display fingerprint sensors.

    Optic sensors used in most of the In-Display fingerprint scanners these days aren’t very accurate and some researchers even discovered a big vulnerability in them, which was patched recently. The vulnerability discovered by Tencent’s Xuanwu Lab gave attackers a free pass, allowing them to bypass the lock screen completely.

    Yang Yu, a researcher from the same team stated that this was a persistent problem present in every In-Display Fingerprint scanner module they tested, also adding that the vulnerability is a design fault of In-display fingerprint sensors.

  • Google’s Move To Open Source BERT May Change NLP Forever

    In 1954, with the success of the Georgetown experiment in which the scientists used a machine to translate random sentences from Russian to English, the field of computational linguistics took giant strides towards building an intelligent machine capable of recognising and translating speech. These models were even used in translations during the Nuremberg trials. Nonetheless, the future of machine translation was nowhere close to the forecast due to sluggish computational devices and scarcity of data to train on.

    [...]

    Bidirectional Encoder Representations from Transformers or BERT, which was open sourced earlier this month, offers a new ground to embattle the intricacies involved in understanding the language models.

    Pre-training a binarised prediction model helps understanding common NLP tasks like Question Answering or Natural language Inference.

    Unidirectional models are efficiently trained by predicting each word conditioned on the previous words in the sentence. However, it is not possible to train bidirectional models by simply conditioning each word on its previous and next words, since this would allow the word that’s being predicted to indirectly “see itself” in a multi-layer model.

  • Lars Wirzenius: Retiring from Debian

    I've started the process of retiring from Debian. Again. This will be my third time. It'll take a little while I take care of things to do this cleanly: uploading packages to set Maintainer to QA, removing myself from Plant Debian, sending the retirement email to -private, etc.

    I've had a rough year, and Debian has also stopped being fun for me. There's a number of Debian people saying and doing things that I find disagreeable, and the process of developing Debian is not nearly as nice as it could be. There's way too much friction pretty much everywhere.

    For example, when a package maintainer uploads a package, the package goes into an upload queue. The upload queue gets processed every few minutes, and the packages get moved into an incoming queue. The incoming queue gets processed every fifteen minutes, and packages get imported into the master archive. Changes to the master archive get pushed to main mirrors every six hours. Websites like lintian.debian.org, the package tracker, and the Ultimate Debian Database get updated at time. (Or their updates get triggered, but it might take longer for the update to actually happen. Who knows. There's almost no transparency.)

    The developer gets notified, by email, when the upload queue gets processed, and when the incoming queue gets processed. If they want to see current status on the websites (to see if the upload fixed a problem, for example), they may have to wait for many more hours, possibly even a couple of days.

  • Linux: Ubuntu 18.04 LTS will be supported for a full decade

    Mark Shuttleworth has announced that Ubuntu 18.04 will be supported for ten years. Long Term Support releases of Ubuntu usually enjoy just five years of support, so this doubling is highly significant.

    Shuttleworth -- the founder of Canonical and Ubuntu -- made the announcement at the OpenStack Summit in Berlin, and the change is a tactical maneuver that will help Ubuntu better compete against the likes of Red Hat/IBM. It is also an acknowledgement that many industries are working on projects that will not see the light of day for many years, and they need the reassurance of ongoing support from their Linux distro. Ubuntu can now offer this.

  • Daniel Stenberg: I’m leaving Mozilla

    It's been five great years, but now it is time for me to move on and try something else.

    During these five years I've met and interacted with a large number of awesome people at Mozilla, lots of new friends! I got the chance to work from home and yet work with a global team on a widely used product, all done with open source. I have worked on internet protocols during work-hours (in addition to my regular spare-time working with them) and its been great! Heck, lots of the HTTP/2 development and the publication of that was made while I was employed by Mozilla and I fondly participated in that. I shall forever have this time ingrained in my memory as a very good period of my life.

    [...]

    I had worked on curl for a very long time already before joining Mozilla and I expect to keep doing curl and other open source things even going forward. I don't think my choice of future employer should have to affect that negatively too much, except of course in periods.

    With me leaving Mozilla, we're also losing Mozilla as a primary sponsor of the curl project, since that was made up of them allowing me to spend some of my work days on curl and that's now over.

    Short-term at least, this move might increase my curl activities since I don't have any new job yet and I need to fill my days with something...

Linux 4.20-rc3

Linux

The only unusual thing last week was my travel - not any code issues.
That caused a few pulls to be delayed by a day or two, but nothing
else.

And now I'm back home, and 4.20-rc3 is out there.

The changes in rc3 are pretty tiny, which means that the statistics
look slightly different from the uysual ones - drivers only account
for less than a third of the patch, for example. But that really isn't
because of anything odd going on anywhere else, it all looks like just
random noise in the distribution of patches. So we have about one
third driver updates, one third arch updates, and one third "core"
(kernel, mm, fs, networking).

If you are hoping to pick-up a new graphics card during the upcoming holiday sales, here is a 20-way NVIDIA GeForce and AMD Radeon Linux gaming benchmark comparison using a wide assortment of GPUs while using the very newest graphics drivers and a variety of OpenGL/Vulkan titles.

In preparation for the Radeon RX 590 launch this week, I've been re-testing my available graphics cards on the latest AMD/NVIDIA drivers and newest kernel (unlike some Windows sites that may regurgitate their existing data points for months at a time, Phoronix tests are always done fresh on the current/latest components). But with the Radeon RX 590 currently being a dud on Linux with the current AMDGPU kernel code, I decided to keep testing including some older graphics cards to make for this twenty-way comparison ahead of Black Friday sales and the holidays.

Linux Kernel: EROFS, Heterogeneous Memory Management, Getting Involved, 4.20-rc3, and DRM ('Secure Output Protocol')

  • There Is Finally A User-Space Utility To Make EROFS Linux File-Systems
    Back when Huawei introduced the EROFS Linux file-system earlier this year, there wasn't any open-source user-space utility for actually making EROFS file-systems. Even when EROFS was merged into the mainline tree, the user-space utility was still non-existent but now that issue has been rectified.
  • The State Of Heterogeneous Memory Management At The End Of 2018
    Heterogeneous Memory Management is the effort going on for more than four years that was finally merged to the mainline Linux kernel last year but is still working on adding additional features and improvements. HMM is what allows for allowing the mirroring of process address spaces, system memory to be transparently used by any device process, and other functionality for GPU computing as well as other device/driver purposes. Jerome Glisse at Red Hat who has spearheaded Heterogeneous Memory Management from the start presented at last week's Linux Plumbers Conference on this unified memory solution.
  • An attempt to create a local Kernel community
    Now I am close to complete one year of Linux Kernel, and one question still bugs me: why does it have to be so hard for someone in a similar condition to become part of this world? I realized that I had great support from many people (especially from my sweet and calm wife) and I also pushed myself very hard. Now, I feel that it is time to start giving back something to society; as a result, I began to promote some small events about free software in the university and the city I live. However, my main project related to this started around two months ago with six undergraduate students at the University of Sao Paulo, IME [3]. My plan is simple: train all of these six students to contribute to the Linux Kernel with the intention to help them to create a local group of Kernel developers. I am excited about this project! I noticed that within a few weeks of mentoring the students they already learned lots of things, and in a few days, they will send out their contributions to the Kernel. I want to write a new post about that in December 2018, reporting the results of this new tiny project and the summary of this one year of Linux Kernel. See you soon :)

  • Wayland Secure Output Protocol Proposed For Upstream - HDCP-Like Behavior
    Collabora developer Scott Anderson sent out a "request for comments" patch series that would add a Secure Output Protocol to the Wayland space. The Secure Output Protocol is for allowing a Wayland client to tell the compositor to only display if it's going to a "secure" output, such as for HDCP-like (High-bandwidth Digital Content Protection) configurations, but there is no mandate at the protocol level about what is the definition of secure -- if anything. This does not impose any DRM per se by Wayland but is mostly intended for set-top-boxes and other closed systems where a Wayland client can reasonably trust the compositor. The Wayland Secure Output Protocol is based upon the work done by Google on their Chromium Wayland code.

Best Linux Desktop Environments: Strong and Stable

A desktop environment is a collection of disparate components that integrate together. They bundle these components to provide a common graphical user interface with elements such as icons, toolbars, wallpapers, and desktop widgets. Additionally, most desktop environments include a set of integrated applications and utilities. Desktop environments (now abbreviated as DE) provide their own window manager, system software that controls the placement and appearance of windows within a windowing system. They also provide a file manager which organizes, lists, and locates files and directories. Other aspects include a background provider, a panel to provide a menu and display information, as well as a setting/configuration manager to customize the environment. Ultimately, a DE is a piece of software. While they are more complicated than most other types of software, they are installed in the same way. Read more

KDE neon upgrade - From 16.04 to 18.04

I am quite happy with the KDE neon upgrade, going from the 16.04 to the 18.04 base. I think it's good on several levels, including improved hardware support and even slightly better performance. Plus there were no crashes or regressions of any kind, always a bonus. This means that neon users now have a fresh span of time to enjoy their non-distro distro, even though it's not really committing to any hard dates, so the LTS is also only sort of LTS in that sense. It's quite metaphysical. On a slightly more serious note, this upgrade was a good, positive experience. I semi-accidentally tried to ruin it, but the system recovered remarkably, the post-upgrade results are all sweet, and you have a beautiful, fast Plasma desktop, replete with applications and dope looks and whatnot. I'm happy, and we shall bottle that emotion for when the need arises, and in the Linux world it does happen often, I shall have an elixir of rejuvenation to sip upon. KDE neon, a surprisingly refined non-distro distro. Read more
