  • OpenCL 2.2 Sees A Maintenance Update With Document Clarifications, Bug Fixes

    While OpenCL 2.2 support by the major hardware vendors' drivers are sadly languishing, a new maintenance release of this year-old OpenCL standard was issued today to provide various bug fixes as well as documentation clarifications to the specification. Additionally, there is also an update to the OpenCL SPIR-V specification.

  • AMD's Compressonator 3.0 Brings Better Texture Compression

    AMD's GPUOpen team has released Compressonator 3.0, the latest major update to this tools collection for dealing with texture and 3D model compression and optimizations for Linux, macOS, and Windows.

    The Compressonator 3.0 release brings improved texture compression, mesh optimizations, mesh compression support, and other enhancements.

  • AMDKFD In Linux 4.18 Bringing Vega GPU Support

    The AMDKFD kernel driver in the upcoming Linux 4.17 has the long-awaited discrete Radeon GPU support working so it can be used with the ROCm/OpenCL compute user-space, but Vega GPU support wasn't ready for this release. Fortunately, it's ready for Linux 4.18.

  • Four Years After Launch, AMD Kaveri Sees Huge Performance Boost On Linux

    For those making use of AMD Kaveri APUs, the latest Linux graphics stack improvements will now yield much better performance -- up to twice as fast in some instances! Here are some benchmarks with Ubuntu 18.04 on the AMD A10-7870K.

  • X.Org Server 1.21 Opens For Development

    Following the long drawn out and feature-packed X.Org Server 1.20 cycle, the 1.21 window officially opened up today.

    Adam Jackson of Red Hat who continues serving as the X.Org Server release manager today did the post-1.20 version bump to begin allowing new feature material to land for this next cycle.

    For the time being xserver Git is living as version 1.20.99.1 and Adam's latest codename is "Carrot and Ginger Soup."

    No release plans have been posted yet, so it remains to be seen if 1.21 will aim to get back on a six-month release cadence like X.Org had been getting good at delivering on. Or if it will be like 1.20 where it was one and a half years in the making.

    Bison and Flex (or any of the yacc/lex family members) are a quick way to generate reliable parsers and lexers for language development. It's easy to write a token recognizer in Flex and a grammar in Bison, and you can readily hook code up to the resulting parsing operation. However, neither Bison nor Flex are really designed for embedded systems where memory is limited and malloc is to be avoided. When starting Newt, I didn't hesitate to use them though; it's was nice to use well tested and debugged tools so that I could focus on other parts of the implementation. With the rest of Newt working well, I decided to go take another look at the cost of lexing and parsing to see if I could reduce their impact on the system.
  • Kano Scores a Disney Partnership, Announces a Star Wars Kit for Later This Year
    Kano creates killer little sets to teach kids how to code and beyond (like the awesome Harry Potter Coding Kit), and today the company is announcing a Disney partnership. The first product will be a Star Wars kit. While other info is scant at the time, Kano says the Star Wars kit will be out “in the second half of 2019.” Alex Klein, Kano’s CEO and co-founder, only teased other details, saying that “Collaborating with Disney is a blessing. We can combine connected, creative technologies with some of the most memorable stories ever told.”

Security: Software Security is a Civil Right, Security Isn’t a Feature, Metasploit and Software Updates

  • Software Security is a Civil Right!
  • Security isn’t a feature
    As CES draws to a close, I’ve seen more than one security person complain that nobody at the show was talking about security. There were an incredible number of consumer devices unveiled, no doubt there is no security in any of them. I think we get caught up in the security world sometimes so we forget that the VAST majority of people don’t care if something has zero security. People want interesting features that amuse them or make their lives easier. Security is rarely either of these, generally it makes their lives worse so it’s an anti-feature to many. Now the first thing many security people think goes something like this “if there’s no security they’ll be sorry when their lightbulb steals their wallet and dumps the milk on the floor!!!” The reality is that argument will convince nobody, it’s not even very funny so they’re laughing at us, not with us. Our thoughts by very nature blame all the wrong people and we try to scare them into listening to us. It’s never worked. Ever. That one time you think it worked they were only pretended to care so you would go away. So it brings us to the idea that security isn’t a feature. Turning your lights on is a feature. Cooking you dinner is a feature. Driving your car is a feature. Not bursting into flames is not a feature. Well it sort of is, but nobody talks about it. Security is a lot like the bursting into flames thing. Security really is about something not happening, things not happening is the fundamental problem we have when we try to talk about all this. You can’t build a plausible story around an event that may or may not happen. Trying to build a narrative around something that may or may not happen is incredibly confusing. This isn’t how feature work, features do positive things, they don’t not do negative things (I don’t even know if that’s right). Security isn’t a feature. So the question you should be asking then is how do we make products being created contain more of this thing we keep calling security. The reality is we can’t make this happen given our current strategies. There are two ways products will be produced that are less insecure (see what I did there). Either the market demands it, which given the current trends isn’t happening anytime soon. People just don’t care about security. The second way is a government creates regulations that demand it. Given the current state of the world’s governments, I’m not confident that will happen either.
  • Metasploit, popular hacking and security tool, gets long-awaited update
    The open-source Metasploit Framework 5.0 has long been used by hackers and security professionals alike to break into systems. Now, this popular system penetration testing platform, which enables you to find, exploit, and validate security holes, has been given a long-delayed refresh. Rapid7, Metasploit's parent company, announced this first major release since 2011. It brings many new features and a fresh release cadence to the program. While the Framework has remained the same for years, the program was kept up to date and useful with weekly module updates.

  • [Slackware] New VLC and Flash
    AV1 is a new video codec by the Alliance for Open Media, composed of most of the important Web companies (Google, Facebook, Netflix, Amazon, Microsoft, Mozilla…). AV1 has the potential to be up to 20% better than the HEVC codec, but the patents license is totally free. VLC supports AV1 since version 3.0.0 but I never added the ‘aom‘ decoder/encoder to my vlc package, since ‘aom’ is the reference implementation of the video format and it does not really perform. The VideoLAN and FFmpeg communities are collaborating on ‘dav1d’ to make this a reference optimized decoder for AV1. Now that ‘dav1d’ has an official release I thought it would be cool to have in the VLC package. Mozilla and Google browsers already have the support for AV1 video playback built-in, so… overdue here.
