  • Some New Operating Systems on Distrotest that Caught My Attention!

    Distrotest is one site that provides a variety of Linux distributions that can be run directly on the browser. Or you can also run it on a remote desktop client application, for example using Remmina. So, you can try various linux distributions online without having to install it or make a live CD.

    when I visited the distrotest. Apparently, there have been many new systems added. However, there are several new systems that caught my attention.

FreeBSD/amd64 images are available on the Hashicorp Atlas site, and can
be installed by running:

    % vagrant init freebsd/FreeBSD-12.1-RC2
    % vagrant up

=== Upgrading ===

The freebsd-update(8) utility supports binary upgrades of amd64 and i386
systems running earlier FreeBSD releases.  Systems running earlier
FreeBSD releases can upgrade as follows:

	# freebsd-update upgrade -r 12.1-RC2

During this process, freebsd-update(8) may ask the user to help by
merging some configuration files or by confirming that the automatically
performed merging was done correctly.

	# freebsd-update install

The system must be rebooted with the newly installed kernel before
continuing.

	# shutdown -r now

After rebooting, freebsd-update needs to be run again to install the new
userland components:

	# freebsd-update install

It is recommended to rebuild and install all applications if possible,
especially if upgrading from an earlier FreeBSD release, for example,
FreeBSD 11.x.  Alternatively, the user can install misc/compat11x and
other compatibility libraries, afterwards the system must be rebooted
into the new userland:

	# shutdown -r now

Finally, after rebooting, freebsd-update needs to be run again to remove
stale files:

	# freebsd-update install

Games: Stellaris, Crusader Kings III and More

Filed under
Gaming
  • Stellaris: Federations and Stellaris: Lithoids Species Pack announced at PDXCON

    PDXCON is now in full swing and the announcement are being handed out like candy. First up, Paradox Interactive and Paradox Development Studio have announced Stellaris: Federations and Stellaris: Lithoids Species Pack.

  • Crusader Kings III announced for release next year, to be more welcoming to new players

    As I suggested they would when setting Crusader Kings II permanently free (but not the DLC), Paradox Interactive have announced Crusader Kings III.

    "Crusader Kings III is a grand medieval simulator where you are free to live out any plausible ruler fantasy that we could think of - but not without challenge." says Henrik Fåhraeus, the Game Director. "Seeing its predecessor explode in popularity was very satisfying, especially considering that user friendliness was never our primary goal. Now we have a chance to address an even larger audience."

  • Prison Architect - Psych Ward: Warden's Edition expansion announced (plus another coming)

    I think we all saw this coming when Paradox Interactive picked up the rights to Prison Architect, with Double Eleven taking on further development. The first proper DLC has been announced at PDXCON named Prison Architect - Psych Ward: Warden's Edition.

    Psych Ward was previously a console exclusive DLC, so it's good to see it make it onto PC. However, it does include new added features not in the original DLC and it will launch along side a free content update for everyone. It's not exactly a small pack either, it actually sounds like it's going to be adding quite a bit to the game. Paradox also gave it a release date of November 21, so you won't exactly have long to wait to really find out.

  • BATTLETECH: Heavy Metal brings more classic 'Mechs and new weapon systems, releasing in November

    Even more news from PDXCON! Harebrained Schemes and Paradox Interactive have now properly announced the BATTLETECH: Heavy Metal expansion to bring more destruction.

  • Hearts of Iron IV: La Résistance expansion and a significant free update announced

    Paradox Development Studio and Paradox Interactive are expanding another of their grand-scale strategy games, with Hearts of Iron IV: La Résistance announced during PDXCON.

    Not just that, as they usually do they also confirmed a "significant" free content update will be released to all players. The free update will include a reworking of the resistance system, interface improvements to battleplans and air operations plus many other "quality of life improvements".

  • Continuing the Counter-Strike 20th anniversary Valve put out skins, plus a possible Operation and update coming

    After starting off the celebration for Counter-Strike turning 20 back in June with the retro version of Dust II, Valve have now added a refreshed version of the map Cache and a themed Weapon Case and Sticker Capsule.

    We're expecting some bigger updates to come but let's go over what they've already done.

    [...]

    VNN's Tyler McVicker also released another of his highly speculative videos talking about lots of other things that could be pointing to a new operation. With a possible update coming that may include: custom Danger Zone modes, a new Danger Zone map, new Danger Zone weapons, co-op missions, hats and other wearable items, player taunts and more being speculated on.

    I personally hope Valve do put out a big update, since their celebration so far has been a bit lacklustre. An old map, a refreshed map and some skins you have to pay for. Not exactly big or exciting really so far. Speaking personally again, I'm still very much enjoying Danger Zone so if they do expand it again I will be quite pleased.

Theme Updates, Offline Upgrades Headline New Additions to Pop!_OS 19.10

Filed under
OS

Offline upgrades are now live on Pop!_OS 19.04, bringing faster, more reliable upgrades. When an upgrade becomes available, it is downloaded to your computer. Then, when you decide to upgrade to the newest version of your OS, the upgrade will overwrite the current version of your software. However, this is not to be confused with an automatic update; your OS will remain on the current version until you yourself decide to upgrade.

To upgrade to 19.10 from a fully updated version of Pop!_OS 19.04, open the Settings application and scroll down on the sidebar menu to the Details tab. In the About panel of the Details tab, you will see a button to download the upgrade. Once the download is complete, hit the button again to upgrade your OS. This will be the standard method of upgrading between Pop!_OS releases going forward.

  • Paragon Looks To Upstream Their Microsoft exFAT Driver For The Linux Kernel

    With the upcoming Linux 5.4 kernel release there is now an exFAT file-system driver based on an old Samsung code drop of their exFAT driver support for mobile devices. This comes after Microsoft made the exFAT specification public recently and gave their blessing for a native Linux driver for the file-system. The Linux developers acknowledge though the current exFAT code is "horrible" and a "pile of crap" but is within the staging area.

    So in Linux 5.4's staging is this preliminary read-write driver for exFAT that continues to be cleaned up and further improved upon. Meanwhile there is also another out-of-tree exFAT Linux driver based on Samsung's sdFAT code that is said to be in better shape than the mainline code. But now there's another option with Paragon Software wanting to upstream their own exFAT driver into the Linux kernel.

  • Brief on Behalf of Amicus Curiae Open Source Hardware Association in Curver Luxembourg, SARL v. Home Expressions Inc., No. 18-2214 (Fed. Cir.)

    Curver Luxembourg, SARL v. Home Expressions Inc. is a case of first impression for the Court of Appeals for the Federal Circuit. The question on appeal is whether a design patent’s scope is tied to the article of manufacture disclosed in the patent.

    In this amicus brief, the Open Source Hardware Association (“OSHWA”) explains the potential effects on open source hardware development, and design practice generally, of untethering design patent protection from the article of manufacture disclosed in the patent. A large percentage of open-source hardware combines both ornamental and functional elements, and industrial design routinely involves applying design concepts from disparate fields in novel ways. To engage in this practice, open-source hardware designers need to know the universe of available source material and its limits. Further, understanding the licensing requirements of open-source hardware begins with understanding how the elements that make up that hardware may or may not be protected by existing law. Accordingly, while many creators of open-source hardware do not seek patent protection for their own creations, an understandable scope of design patent protection is nonetheless essential to their ability to collaborate with other innovators and innovate lawfully.

    The brief argues that the District Court in the case—and every district court that has considered the issue—correctly anchored the patented design to the article of manufacture when construing the patent. The brief explains that anchoring the patented design to the disclosed article of manufacture is the best approach, for several reasons. Connecting the patented design to the disclosed article of manufacture calibrates the scope of design patent protection to the patentee’s contribution over the prior art. It avoids encumbering the novel and nonobvious application of prior designs to new articles of manufacture, a fundamental and inventive practice of industrial design. It aligns the scope of design patent protection with its purpose: encouraging the inventive application of a design to an article of manufacture. This balances protection for innovative designs with later innovators’ interest in developing future designs. Finally, anchoring the patented design to the disclosed article of manufacture helps fulfill design patent law’s notice function by clarifying the scope of protection.

    It looks like as soon as Linux 5.5 is where the AMDGPU kernel driver could be ready with Panel Self Refresh (PSR) support for enabling this power-savings feature on newer AMD laptops.

    While Intel's Linux driver stack has been supporting Panel Self Refresh for years, the AMD support in their open-source Linux driver code has been a long time coming. We've seen them working towards the support since Raven Ridge and now it appears the groundwork has been laid and they are ready to flip it on within the Display Core "DC" code.

  • GNU poke: Dealing with alternatives - Unions in Poke

    Computing with data whose form is not the most convenient way to be manipulated, like is often the case in unstructured binary data, requires performing a preliminary step that transforms the data into a more convenient representation, usually featuring a higher level of abstraction. This step is known in computer jargon as unmarshalling, when the data is fetch from some storage or transmission media or, more generally, decoding.

    Once the computation has been performed, the result should be transformed back to the low-level representation to be stored or transmitted. This is performed in a closing step known as marshalling or, more generally, encoding.

    Consider the following C program whose purpose is to read a 32-bit signed integer from a byte-oriented storage media at a given offset, multiply it by two, and store the result at the same offset.

    One of the key features in the release is an update to GNU Make to version 4.2, which provides a number of bug fixes, and enables ‘–output-sync’ to avoid interleaving output with error messages, the team explained. This is enabled by default with ndk-build.

    Additionally, GDB, the GNU project debugger, has been updated to version 8.3, which includes fixes for debugging modern Intel CPUs.

  • What is the history behind C Programming and Unix?

    If you think C programming and Unix are unrelated, then you are making a big mistake. Back in the 1970s and 1980s, if the Unix engineers at Bell Labs had decided to use another programming language instead of C to develop a new version of Unix, then we would be talking about that language today.

    The relationship between the two is simple; Unix is the first operating system that is implemented with a high-level C programming language, got its fame and power from Unix. Of course, our statement about C being a high-level programming language is not true in today’s world.

    This article is an excerpt from the book Extreme C by Kamran Amini. Kamran teaches you to use C’s power. Apply object-oriented design principles to your procedural C code. You will gain new insight into algorithm design, functions, and structures. You’ll also understand how C works with UNIX, how to implement OO principles in C, and what multiprocessing is.

This is true for software development companies (who develop apps and services for other businesses), as well as companies looking to roll out web-based and mobile applications with an unheard of speed and reliability.

    But with any new technology, comes hurdles. One of the biggest hurdles for any business is security. Data breaches have become rampant and it’s on the shoulders of every company to do everything in their power to make sure they are rolling out technology that is as secure as possible. This idea should certainly be applied to containers.

    But what can you do to use containers security? Fortunately, there are a few steps that you can take from the very beginning.

  • Pensando Systems Exits Stealth Mode With Plans To Take On Amazon AWS

    While normally we don't cover hardware start-ups on Phoronix, Pensando Systems has just exited stealth and given their focus will be heavily involved with Linux and in fact already have their first kernel driver mainlined.

    After announcing a $145 million (USD) Series-C round, Pensando Systems exited "stealth" and revealed the first details of what they are trying to achieve with this company led by many ex-Cisco staff.

    [...]

    Pensando has been on our radar since as I wrote about last month when they were just a stealth networking startup they already upstreamed their first Linux kernel driver. In the Linux 5.4 kernel is a Pensando "Ionic" driver for a family of network adapters. In this week's press release, Pensando didn't specifically call out Ionic but presumably is the backbone to their hardware. Now that they are beginning to talk about their ambitions, hopefully we see more Linux kernel patches from them soon.

SUSE/OpenSUSE: Ceph and OpenSUSE's Tumbleweed Progress

  • Can I deploy Ceph on older hardware?

    You just retired a bunch of servers and disk arrays, but before you place hundreds of thousands or millions of dollars’ worth of equipment on the curb, you’re wondering if you can use it for a Ceph-based storage solution like SUSE Enterprise Storage. The answer is: maybe.

    SUSE prides itself on supporting a wide range of hardware, from blades to retail terminals to IoT devices. In fact, SUSE makes it possible to easily deploy a wide range of software on that hardware and certify it will work through the SUSE YES Certification Program. SUSE Yes Certification assures your IHV equipment is fully compatible with SUSE software, including SUSE Enterprise Storage.

  • EPA Rule Will Make Its Custom Code Open Source By Default

    The Environmental Protection Agency is getting ready to default to making all its custom code open source, finally meeting an Office of Management and Budget policy instituted during the last administration.

    The EPA will publish a notice Friday in the Federal Register soliciting public comment on a new open-source policy that will be added to the agency’s acquisition regulations. The clause—which will be added to all EPA contracts that include the use of open-source software or the development of custom code that may or may not be shared widely—will require contractors to provide the agency with all “underlying source code, license file, related files, build instructions, software user’s guides, automated test suites and other associated documentation as applicable,” according to the notice.

  • Environmental Protection Agency Acquisition Regulation (EPAAR); Open Source Software

    A Proposed Rule by the Environmental Protection Agency on 10/18/2019

    [...]

    The EPA is writing a new EPAAR clause to address open source software requirements at EPA, so that the EPA can share custom-developed code as open source code developed under its procurements, in accordance with Office of Management and Budget's (OMB) Memorandum M-16-21, Federal Source Code Policy: Achieving Efficiency, Transparency, and Innovation through Reusable and Open Source Software. In meeting the requirements of Memorandum M-16-21 the EPA will be providing an enterprise code inventory indicating if the new code (source code or code) was custom-developed for, or by, the agency; or if the code is available for Federal reuse; or if the code is available publicly as open source code; or if the code cannot be made available due to specific exceptions.

Samsung discontinues ‘Linux on DeX’ program

  • Samsung discontinues ‘Linux on DeX’ program, removing support w/ Android 10

    Late last year, Samsung and Canonical partnered on an app that allowed select Galaxy phones to run a full Linux desktop on top of Android. Less than a year later, Samsung has announced that they’re discontinuing the Linux on DeX program, coinciding with the update to Android 10.

    One of the sci-fi-style dreams that many of us have had since the onset of smartphones is the idea of plugging your phone into a desktop-size monitor to get a desktop-style experience. Through the years, many have attempted it in earnest, and the latest offering from Samsung brought an interesting approach.

  • Samsung Calls It Quits on the ‘Linux on DeX’ Project

    Samsung DeX, if you have heard of it, allows the users to turn their Galaxy phones into desktop PCs simply by connecting a monitor and other peripherals. The company made DeX more welcoming and useful for Galaxy flagship users by partnering with Canonical earlier last year. It made it possible for users to run a full Linux desktop instance on its DeX-supported flagship phones.

    This was an amazing feature for developers and users who didn’t really like carrying a laptop with them. They could rely on their Galaxy flagship (including the Galaxy S and Note-series) for a desktop-like experience, running Ubuntu on the move. However, the response to Linux on DeX seems to have been lackluster and Samsung has decided to shutter this project.

  • Samsung is discontinuing Linux support on Dex

    Samsung goes on to explain that starting with its Android 10 beta ROMS, already rolling out on certain devices, Linux support will be removed from Dex altogether. This does make us wonder if, perhaps, the third-party OS emulation setup Samsung was employing to get Linux to work in the first place somehow breaks certain rules or security policies Google implemented with the latest Android version.

    Regardless of whether or not this is the case, if you are currently using Linux on Dex, you definitely want to start keeping regular backups of your data. Since, given current developments even staying on Android 9 and not updating your phone's Android OS still might not be a sure-fire way to keep the feature running.

To space and beyond with open source

Filed under
OSS

The Cambridge Dictionary defines curiosity as "an eager wish to know or learn about something." It's curiosity that fuels our drive to acquire knowledge about outer space, but what drives our curiosity, our "eager wish," in the first place?

I believe that our curiosity is driven by the desire to escape the unpleasant feeling of uncertainty that is triggered by acknowledging our lack of knowledge. The intrinsic reward that comes from escaping uncertainty pushes us to find a correct (or at least a less wrong) answer to whatever question is at hand.

If we want space discovery to advance at a faster pace, we need more people to become aware of the rewards that are waiting for them when they make the effort and discover answers for their questions about the universe. Space discovery is admittedly not an easy task, because finding correct answers requires following rigorous methods on a long-term scale.

Luckily, open source initiatives are emerging that make it easier for people to get started exploring and enjoying the beauty of outer space.

Announcing the release of LTTng 2.11

Linux

We're happy to announce the release of LTTng 2.11 "Lafontaine".
This is a combined release announcement for the 2.11.0 - "Lafontaine" release of the LTTng Tools, LTTng UST, and LTTng modules projects.
This release is named after a modern Saison beer from Montréal's Oshlag microbrewery. It is a refreshing, zesty, rice beer with hints of fruit and spices. Some even say it makes for a great Somaek when mixed with Chamisul Soju, not that we've tried!
Lafontaine is also a tongue-in-cheek reference to a water leak that affected EfficiOS's offices during the development of this release.

Games: Stellaris, Crusader Kings III and More

  • Stellaris: Federations and Stellaris: Lithoids Species Pack announced at PDXCON

    PDXCON is now in full swing and the announcement are being handed out like candy. First up, Paradox Interactive and Paradox Development Studio have announced Stellaris: Federations and Stellaris: Lithoids Species Pack.

  • Crusader Kings III announced for release next year, to be more welcoming to new players

    As I suggested they would when setting Crusader Kings II permanently free (but not the DLC), Paradox Interactive have announced Crusader Kings III. "Crusader Kings III is a grand medieval simulator where you are free to live out any plausible ruler fantasy that we could think of - but not without challenge." says Henrik Fåhraeus, the Game Director. "Seeing its predecessor explode in popularity was very satisfying, especially considering that user friendliness was never our primary goal. Now we have a chance to address an even larger audience."

  • Prison Architect - Psych Ward: Warden's Edition expansion announced (plus another coming)

    I think we all saw this coming when Paradox Interactive picked up the rights to Prison Architect, with Double Eleven taking on further development. The first proper DLC has been announced at PDXCON named Prison Architect - Psych Ward: Warden's Edition. Psych Ward was previously a console exclusive DLC, so it's good to see it make it onto PC. However, it does include new added features not in the original DLC and it will launch along side a free content update for everyone. It's not exactly a small pack either, it actually sounds like it's going to be adding quite a bit to the game. Paradox also gave it a release date of November 21, so you won't exactly have long to wait to really find out.

  • BATTLETECH: Heavy Metal brings more classic 'Mechs and new weapon systems, releasing in November

    Even more news from PDXCON! Harebrained Schemes and Paradox Interactive have now properly announced the BATTLETECH: Heavy Metal expansion to bring more destruction.

  • Hearts of Iron IV: La Résistance expansion and a significant free update announced

    Paradox Development Studio and Paradox Interactive are expanding another of their grand-scale strategy games, with Hearts of Iron IV: La Résistance announced during PDXCON. Not just that, as they usually do they also confirmed a "significant" free content update will be released to all players. The free update will include a reworking of the resistance system, interface improvements to battleplans and air operations plus many other "quality of life improvements".

  • Continuing the Counter-Strike 20th anniversary Valve put out skins, plus a possible Operation and update coming

    After starting off the celebration for Counter-Strike turning 20 back in June with the retro version of Dust II, Valve have now added a refreshed version of the map Cache and a themed Weapon Case and Sticker Capsule. We're expecting some bigger updates to come but let's go over what they've already done. [...] VNN's Tyler McVicker also released another of his highly speculative videos talking about lots of other things that could be pointing to a new operation. With a possible update coming that may include: custom Danger Zone modes, a new Danger Zone map, new Danger Zone weapons, co-op missions, hats and other wearable items, player taunts and more being speculated on. I personally hope Valve do put out a big update, since their celebration so far has been a bit lacklustre. An old map, a refreshed map and some skins you have to pay for. Not exactly big or exciting really so far. Speaking personally again, I'm still very much enjoying Danger Zone so if they do expand it again I will be quite pleased.

Android Leftovers

Theme Updates, Offline Upgrades Headline New Additions to Pop!_OS 19.10

Offline upgrades are now live on Pop!_OS 19.04, bringing faster, more reliable upgrades. When an upgrade becomes available, it is downloaded to your computer. Then, when you decide to upgrade to the newest version of your OS, the upgrade will overwrite the current version of your software. However, this is not to be confused with an automatic update; your OS will remain on the current version until you yourself decide to upgrade. To upgrade to 19.10 from a fully updated version of Pop!_OS 19.04, open the Settings application and scroll down on the sidebar menu to the Details tab. In the About panel of the Details tab, you will see a button to download the upgrade. Once the download is complete, hit the button again to upgrade your OS. This will be the standard method of upgrading between Pop!_OS releases going forward. Read more Also: Pop!_OS 19.10 Released With Tensorman Tool For Tensorflow Management, GNOME 3.34
