Mesa 17.3 Coming Soon, X.Org Server 1.19.5 is Out

Filed under
Graphics/Benchmarks
  • Mesa 17.3 Will Be Branching Soon For Releasing In Mid-November

    Feature development for Mesa 17.3 will be over soon in order to get this quarterly update to Mesa3D shipping next month.

    Release manager Emil Velikov is planning to issue the feature freeze and first release candidate next Friday, 20 October. That will mark the deadline for getting major features/improvements into Mesa 17.3, after which point it will be reserved for bug fixes.

  • xorg-server 1.19.5

    One regression fix since 1.19.4 (mea culpa), and fixes for CVEs 2017- 12176 through 2017-12187. C is a terrible language, please stop writing code in it.

  • X.Org Server 1.19.5 Released To Fix Another Handful Of Security Vulnerabilities

    Ouch, so basically a lot of potential for buffer overflows. Sadly, this is not the first time we have seen a big batch of X.Org Security vulnerabilities and security researchers in the past have generally characterized X.Org security as even worse than it looks.

Filed under
Android
Linux

Olimex unveiled a new “SOM204” form factor for computer-on-modules and previewed an open spec, Allwinner A20 based “A20-SOM204” COM built in the new format.

Last week Olimex announced it was standardizing all future computer-on-modules on a new “SOM204” form factor with an 204-pin SODIMM edge connector. It also previewed the first SOM204 module: the “A20-SOM204,” based on the Allwinner A20 SoC. The module will ship in November with an evaluation board at prices comparable to that of the company’s earlier A20-SOM, says Olimex. Schematics for the A20-SOM204 COM and A20-EVB204 carrier board are already available for free download.

10 open source alternatives to Minecraft

Filed under
OSS

There's no denying that Minecraft is a favorite game for millions. And being written in Java enables it to run on a variety of platforms, including Linux. With a huge modding community, there are countless Minecraft tinkerers out there who would love to be able to get under the hood and play around with the source code themselves. Unfortunately, the source is not available to the general public.

But there's good news. Minecraft's popularity has led to many attempts to recreate the game, and others in a similar vein, as open source software. Interested in a free Minecraft alternative? Here's a quick look at some clones and derivatives out there that you really ought to check out.

Servers: Containers, Buzzwords, and Debian

  • Using Containers? Look for the OCI Seal of Approval

    Some standards have been set for container technology. That's a good thing. Without standards, everybody working on developing a technology goes in separate directions, with no thought about how their implementation will work and play with the work being done by others. Without standards, vendor lock-in is practically unavoidable.

    Until July, when the Open Container Initiative (OCI) released version 1.0 of its specification, there were no standards when it came to containers. Products from one vendor didn't necessarily work with the offerings from another. Obviously, this was a problem for DevOps working in diverse environments.

  • 6 ways to work with database admins in the DevOps world

    DevOps is defined as "unifying the operations and engineering teams," in order to foster a culture of cross-team collaboration, codify how infrastructure is built, and become a more data-driven organization. But it seems databases and the teams that care for them are treated as an exception to this environment. In most companies, databases are still treated like walled gardens, with the database hosts tended to like delicate flowers and the database administrators (DBAs) guarding any and all access to them.

    This walled-garden attitude invariably affects the rest of the organization, from tech ops, to delivery engineering, all the way to product planning, as everyone tries to work around the datastore. Ultimately this reduces the benefits of an agile approach to software development, which is a problem for companies that have been running for a few years and have reached a solid financial footing with loyal paying customers, but are having a hard time shedding that startup skin (the one that flies by the seat of its pants), and are feeling the pressure to achieve a sense of stability in existing and future offerings.

  • Container Runtime Brings Greater Flexibility to Kubernetes and BOSH

    The Cloud Foundry Foundation on Wednesday launched Cloud Foundry Container Runtime, or CFCR, as the default deployment and management platform for containers using Kubernetes and BOSH.

  • Debian and the GDPR

    GDPR is a new EU regulation for privacy. The name is short for "General Data Protection Regulation" and it covers all organisations that handle personal data of EU citizens and EU residents. It will become enforceable May 25, 2018 (Towel Day). This will affect Debian. I think it's time for Debian to start working on compliance, mainly because the GDPR requires sensible things.

  • XikiHub: The Social Command Line

    Brief: A new Linux project named XikiHub has been spotted on Kickstarter. It aims to add a social community feature right into the Linux command line.

  • qTox – An Open Source P2P Instant Messaging and VoIP App

    As you probably already know, GNU/Linux has no shortage of VoIP apps. We’ve written on Wire and Discord. And we even compiled a list of The 10 Best Instant Messaging Apps for Linux.

    Today, we’ve got a new app to add to our list of instant messaging apps and it goes by the name of qTox.

    qTox is a free and open source p2p instant messaging, audio and video calls app and is (apparently) the most feature-rich Tox client. As a powerful Tox client, it follows Tox’s design guidelines while maintaining a uniform UI/UX across all the major platforms.

  • Dash to Panel Adds Support for Dynamic Transparency

    The popular Dash to Panel GNOME extension has been updated to support GNOME 3.26.

    The upcoming release will also include support for dynamic transparency, a bit of desktop eye candy that was introduced by GNOME developers in the recent GNOME 3.26 release.

    Dynamic Transparency in Ubuntu 17.10 works on both the top bar (the panel across the top of the screen) and the Ubuntu Dock. When an app window touches either element, or is maximised, the transparency of the dock and panel is reduced to help improve legibility.

  • The Slack Threat

    During a long era, electronic mail was the main communication tool for enterprises. Slack, which offer public or private group discussion boards and instant messaging between two people, challenge its position, especially in the IT industry.

    Not only Slack has features known and used since IRC launch in the late ’80s, but Slack also offers file sending and sharing, code quoting, and it indexing for ulterior searches everything that goes through the application. Slack is also modular with numerous plug-in to easily add new features.

    [...]

    Slack is a Web service which uses mainly Amazon Web services and most specially Cloudfront, as stated by the available information on Slack infrastructure.

    Even without a complete study of said infrastructure, it’s easy to state that all the data regarding many innovative global companies around the world (and some of them including for all their internal communication since their creation) are located in the United States, or at least in the hands of a US company, which must follow US laws, a country with a well-known history of large scale industrial espionage, as the whistleblower Edward Snowden demonstrated it in 2013 and where company data access has no restriction under the Patriot Act, as in the Microsoft case (2014) where data stored in Ireland by the Redmond software editor have been given to US authorities.

    [...]

    Officially, Slack stated that “No financial or payment information was accessed or compromised in this attack.” Which is, and by far, the least interesting of all data stored within Slack! With company internal communication indexed—sometimes from the very beginning of said company—and searchable, Slack may be a potential target for cybercriminal not looking for its users’ financial credentials but more their internal data already in a usable format. One can imagine Slack must give information on a massive data leak, which can’t be ignored. But what would happen if only one Slack user is the victim of said leak?

    [...]

    Because Slack service subscription in the long term put the company continuously at risk. Maybe it’s not the employees’ place to worry about it, they just have to do their job the more efficiently possible. On the other side, the company management, usually non-technical, may not be aware of what risks will threaten their company with this technical choice. The technical management may pretend to be omniscient, nobody is fooled.

  • Linux LTS Kernel Support Extended to 6 Years

    Despite being a free and open source OS, Linux has one of the quickest development cycles. Every 70 days, a major new version of the Linux kernel rolls out. This deprecates any older versions except for the few Long Term Support releases. In a sign of changing times, the Linux kernel lifetime is getting a major boost. From now on, the Linux LTS kernel will be supported for a whole 6 years. Jumping up to 6 years is a tripling of the current 2 year support period. This is especially goods news for Android.

  • RADV Vulkan Driver Gets An On-Disk Shader Cache

    The RADV Radeon Vulkan driver in Mesa now supports an on-disk shader cache.

    Timothy Arceri working for Valve who previously spearheaded the RadeonSI OpenGL on-disk shader cache support has added a similar on-disk shader cache for the RADV Vulkan driver. Vulkan supports the concept of a pipeline cache for reusing cached objects between pipelines and runs of a game/application.

  • Qt Creator 4.5 Beta released

    We are happy to announce the release of Qt Creator 4.5 Beta!

    There has been very little time between the 4.4 release and the 4.5 feature freeze, but 4.5 still comes with a bunch of very nice improvements.

    Locator now does fuzzy camel case matching in the same way as code completion does. Type “c andesu” in locator to open the “AndroidDebugSupport” class.

  • How to Enable Fractional Scaling in Gnome

    Fractional scaling is practically necessary if you’re running a HiDPI display, and you want your desktop to scale uniformly to match your display. It’s always been an issue on Linux, but the latest version of the GNOME desktop has implemented a true fractional scaling feature to keep your desktop looking good.

    Even though GNOME 3.26 does have fractional scaling support, it wasn’t mature enough to make the release. As a result, it’s still a testing feature that you need to enable yourself.
