Ubuntu 14.10's Lack Of X.Org Server 1.16 Gets Blamed On AMD

Filed under
Graphics/Benchmarks

Yesterday I wrote about Ubuntu 14.10 not yet having X.Org Server 1.16 even though the first beta was issued this week and there's been a testing package repository for more than one month. This lack of X.Org Server 1.16 thus far is apparently due to AMD with not yet having a supportive Catalyst driver.

In the comments to yesterday's story, Timo Aaltonen of Canonical and part of their X/graphics team responded. "no fglrx, can't force people to switch to radeon and likely regress, on newer hw at least."

So Canonical is keeping away from using the latest X.Org code since the Catalyst (fglrx) driver doesn't yet support it and they don't want to regress users by forcing them to use the improving but still less than perfect open-source driver. Canonical's effectively bowing down to a binary blob.

Android 4.4, KitKat was released on October 31, 2013, or at least, that's what you can say about one device: the Nexus 5. For the rest of the ecosystem, the date you got KitKat—if you got KitKat—varied wildly depending on your device, OEM, and carrier.

Akademy 2014: Navigating the tracks

Filed under
KDE

I meant to write a post about the upcoming Akademy for a while now. Since I submitted quite a few sessions (obviously requiring preparation) and I had to prepare for the KDE Frameworks BoF, I never quite found the time... until now! I'm all done! Actually I just have to pack my bags and hit the road at that point. It's probably the first Akademy where I'm ready four days before the first flight of my journey.

Low-Spec Hardware? Try these Desktop Environments

Filed under
GNU
Linux

Popular Linux distributions for beginners typically default to one of two desktop environments, KDE or GNOME. Both of these environments provide users with an intuitive and attractive desktop, as well as offering all the applications users love, ranging from multimedia software, games, administration programs, network tools, educational applications, utilities, artwork, web development tools and more. However, these two desktops focus more on providing users with a modern computing environment with all the bells and whistles, rather than minimising the amount of system resources they use.

Filed under
OS
OSS

The OpenELEC devs have released yet another Beta version of their embedded operating systems and they are getting really close to get a new stable version out the door. Some of the major components have been updated as well and the Raspberry Pi users should be really thrilled about this latest upgrade, as it includes some interesting changes for them as well.

"This release includes some bugfixes, security fixes and improvements since OpenELEC-4.1.4. Besides the usual bugfixes and package updates we updated XBMC to XBMC Gotham 13.2 final, FFmpeg to ffmpeg-2.3.3, Mesa to Mesa-10.3-rc1and systemd to systemd-216. We fixed crashes while playing FLAC files with ID3v2 tags, optimized some software packages and updated the RaspberryPi firmware to include the last fixes and features," said the devs in the official announcement.

MSI Motherboard BIOS Updating Remains A Pain For Linux Users

Filed under
Hardware

In recent years with more motherboard vendors enabling the updating of the BIOS/UEFI from within the setup utility itself and support loading the BIOS file off a USB thumb drive or other storage, it's generally easier for Linux users and all around a smoother process than the days of having to make a MS-DOS start-up floppy disk or similar. For most of these BIOS updates, Windows is generally not required as you can just head on over to the vendor's web-site, download a zipped up copy of the BIOS, transfer it to a USB drive, and reboot into the UEFI setup utility and flash away.

Some vendors will package their BIOS file inside an EXE that has to be executed that will then extract the file right away, but fortunately there's many programs capable of straightaway extracting the files from the EXE or the worst case scenario is generally just running the EXE under Wine. As a Linux user, with MSI motherboards their BIOS packaging takes it to an additional level of annoying and for some Linux users could be show-stopping.

Chromebook Pixel revisited: 18 months with Google's luxury laptop

Google

When you stop and think about it, it's kind of astonishing how far Chromebooks have come.

It was only last February, after all, that Google's Chromebook Pixel came crashing into our lives and made us realize how good of an experience Chrome OS could provide.

At the time, the Pixel was light-years ahead of any other Chromebook in almost every possible way: From build quality to display and performance, the system was just in a league of its own. And its price reflected that status: The Pixel sold for a cool $1300, or $1450 if you wanted a higher-storage model with built-in LTE support.

Why I Hate Non-Free Software

Filed under
OSS

I know why authours of software include such restrictions, to make sure they get paid per whatever. On the other hand, we should not have to enslave ourselves and our families in order to use a smooth, convenient application on our PCs. That’s like selling our children or self-flagellation before having any fun at all to nullify evil. It’s just evil to accept such restrictions. The licence began with “PLEASE READ THIS LICENCE AGREEMENT CAREFULLY BEFORE USING THIS SOFTWARE. IF YOU USE THIS SOFTWARE THEN YOU AGREE TO BE BOUND BY THE TERMS OF THIS LICENCE AGREEMENT.” Sweet, eh? I did not agree and purged the .deb from my system. I am not a slave. I do not agree to be bound in slavery to the authours of software. To add insult to injury, the authours presume to enslave us while we perform them the free service of testing their beta-software.

  • What to expect from Scylla Summit 2019

    Scylla (the company) takes its name directly from Scylla [pronounced: sill-la], a Greek god sea monster whose mission was to haunt and torment the rocks of a narrow strait of water opposite the Charybdis whirlpool. Outside of Greek history, Scylla is an open source essentially distributed NoSQL data store that uses a sharded design on each node, meaning each CPU core handles a different subset of data.

  • Licence to grill: A year on, MongoDB's Eliot Horowitz talks to The Reg about SSPL

    A year after its controversial switch to the Server Side Public License (SSPL), and with new products livening up the summer, MongoDB remains unrepentant. The change was aimed at making vendors selling a service using the company's code share the source of applications used to run the service as well as any tweaks. The move appeared to be aimed squarely at cloud vendors, content to "capture all the value and give nothing back to the community," as Dev Ittycheria, CEO of MongoDB, told us at the time. Elements of the open source community were less than impressed. The Open Source Initiative (OSI) rejected the company's attempts to get the licence approved and eventually MongoDB withdrew the thing from the process, although the company continued to use it for its own products. Indeed, at MongoDB's London .Local event, where we met co-founder and CTO Eliot Horowitz, the company was trumpeting the opening up of its Compass GUI for MongoDB under the SSPL.

  • The love and the lament: Percona CEO details state of open source data

    Open source has changed, obviously it has. Starting from its origins among the hobbyist programmers and hackers who dared to defy the proprietary Silicon Valley behemoths, the open community-centric model for software development has now been widely adopted by the commercial software sector. In many cases, open source has become the norm for modern platforms, tools and applications. But how has this affected the nature of open development and what impact has this shift left in its wake on the data landscape that we view today?

Stateful Functions enables users to define loosely coupled, independent functions with a low footprint that can interact consistently and reliably in a shared pool of resources. Ververica will propose the project, licensed under Apache 2.0, to the Apache Flink community as an open source contribution.

  • DataStax offers bidirectional data dexterity for Apache Kafka

    DataStax has opened up ‘early access’ to its DataStax Change Data Capture (CDC) Connector for Apache Kafka, the open source stream-processing (where applications can use multiple computational units, similar to parallel processing) software platform. As a company, DataStax offers a commercially supported ‘enterprise-robust’ database built on open source Apache Cassandra. Stream processing is all about speed and cadence, so, the DataStax CDC Connector for Apache Kafka gives developers ‘bidirectional data movement’ between DataStax, Cassandra and Kafka clusters.

Security: WireGuard, SafeBreach and More

  • WireGuard Snapshot `0.0.20191012` Available
    -----BEGIN PGP SIGNED MESSAGE-----
    Hash: SHA256
    
    Hello,
    
    A new snapshot, `0.0.20191012`, has been tagged in the git repository.
    
    Please note that this snapshot is a snapshot rather than a final
    release that is considered secure and bug-free. WireGuard is generally
    thought to be fairly stable, and most likely will not crash your
    computer (though it may).  However, as this is a snapshot, it comes
    with no guarantees; it is not applicable for CVEs.
    
    With all that said, if you'd like to test this snapshot out, there are a
    few relevant changes.
    
    == Changes ==
    
      * qemu: bump default version
      * netns: add test for failing 5.3 FIB changes
      
      Kernels 5.3.0 - 5.3.3 crash (and are probably exploitable) via this one liner:
      
      unshare -rUn sh -c 'ip link add dummy1 type dummy && ip link set dummy1 up && ip -6 route add default dev dummy1 && ip -6 rule add table main suppress_prefixlength 0 && ping -f 1234::1'
      
      We fixed this upstream here:
      
      https://git.kernel.org/pub/scm/linux/kernel/git/davem/net.git/commit/?id=ca7a03c4175366a92cee0ccc4fec0038c3266e26
      
      This is relevant to WireGuard because a very similar sequence of commands is
      used by wg-quick(8).
      
      So, we've now added some tests to catch this code path in the future. While
      the bug here was a random old use-after-free, the test checks the general
      policy routing setup used by wg-quick(8), so that we make sure this continues
      to work with future kernels.
      
      * noise: recompare stamps after taking write lock
      
      We now recompare counters while holding a write lock.
      
      * netlink: allow preventing creation of new peers when updating
      
      This is a small enhancement for wg-dynamic, so that we can update peers
      without readding them if they've already been removed.
      
      * wg-quick: android: use Binder for setting DNS on Android 10
      
      wg-quick(8) for Android now supports Android 10 (Q). We'll be releasing a new
      version of the app for this later today.

  • SafeBreach catches vulnerability in controversial HP Touchpoint Analytics software

    Now the feature is embroiled in another minor controversy after security researchers at SafeBreach said they uncovered a new vulnerability. HP Touchpoint Analytics comes preinstalled on many HP devices that run Windows. Every version below 4.1.4.2827 is affected by what SafeBreach found. In a blog post, SafeBreach Labs security researcher Peleg Hadar said that because the service is executed as "NT AUTHORITY\SYSTEM," it is afforded extremely powerful permissions that give it wide access. "The CVE-2019-6333 vulnerability gives attackers the ability to load and execute malicious payloads using a signed service. This ability might be abused by an attacker for different purposes such as execution and evasion, for example: Application Whitelisting Bypass Signature Validation Bypassing," Hadar wrote. [...] The company has long had to defend HP Touchpoint Analytics against critics who say it gives HP unnecessary access to users' systems. When it first became widely noticed in 2017, dozens of users complained that they had not consented to adding the system.

But the true measure of success of any programming language is the projects that developers create with it. Go has proven itself as a first choice for fast development of network services, software infrastructure projects, and compact and powerful tools of all kinds.

    By an anonymous commenter, I got pointed to that Unicode (in Qt) is slightly more complicated than I had considered when writing the code: I missed to handle planes beyond the Basic Multilingual Plane (BMP) and the ‘surrogates’ between code points 0xD800 and 0xDFFF. In a series of recently pushed Git commits I addressed problem of surrogates and fixed some more issues. Some preparatory work has been done to support more planes in the future, but as of now, only the BMP is supported. For details, please have a look at the five commits posted on 2019-10-12.
