  • NAB 2019: Haivision Announces Peer-to-Peer Low-Latency Streaming for Its SRT Framework

    Prior to releasing SRT P2P to the open-source community, Haivision is seeking partners to collaborate and stress-test the technology at scale.

    [...]

    SRT P2P is the latest development for the SRT (Secure Reliable Transport) initiative that Haivision started in 2017 when the company open-sourced the SRT protocol and technology stack. SRT has been endorsed as a low-latency contribution and distribution streaming protocol by more than 200 companies across the broadcast and streaming industries. With a focus on video delivery, SRT P2P extends the SRT initiative to create a comprehensive framework for high-performance streaming from contribution through distribution and into delivery.

  • Netflix and Intel to Deploy AV1 CODEC For Content Streaming

    At The National Association of Broadcasters Show today, Intel and Netflix announced a new high-performance video codec that is available as open source and royalty-free to content creators, developers and service providers. Scalable Video Technology for AV1 (SVT-AV1) offers performance and scalability in video processing.

    AV1 is a royalty-free codec and offers improved compression compared to vp9 or hevc, the video bandwidth reduction can run upwards to 30 to 40 percent, without you seeing a difference. The best thing yet, this is a royalty-free model. 

  • NAB '19: Netflix and Intel Release SVT-AV1 Codec as Open Source

    This morning at NAB, Intel and Netflix together announced the SVT-AV1 codec which is capable of real-time 4K/60p 10-bit encoding when running on Intel Xeon Scalable processors and Intel Xeon D processors. To our knowledge, this is the first software-only AV1 implementation capable of real-time encoding and it represents an order of magnitude acceleration of AV1 encoding. The companies released SVT-AV1, or Scalable Video Technology for AV1, into the open source community for immediate availability.

Libreoffice vs Apache OpenOffice: how to choose the right free office suite for you

When it comes to free office software, there are two main choices: LibreOffice and OpenOffice (or, to give it its proper name, Apache OpenOffice). The two are remarkably similar, so how can you choose the right one for you? First, it's worth thinking carefully about whether you need desktop office software at all. Provided you have an internet connection, Google Docs, Sheets and Slides might offer everything you need, without the need to install anything, and with the extra bonus that everything you create will be automatically saved to the cloud. No more lost documents, or having to email work to yourself. Read more

  • How do you say SUSE?
    SUSECON 2019 has come and gone and was definitely one for the books. Whether you were able to attend the event in person or not, you can still view plenty of videos and content that was shared at the event. One of my favorite videos from the week was “How do you say SUSE” -which comically reminded attendees how to properly say “SUSE.” Don’t quite know exactly how to pronounce SUSE? We’ve got you covered….Broadway musical style. The keynote videos from each day are not to be missed as well as the series of amazing music parody videos that have recently been created. One of the major take-a-ways this year was the recent announcement that as of March 15, not only did SUSE become an independent company, we are now the largest independent open source company in the industry.
  • In 2019, Most Linux Distributions Still Aren't Restricting Dmesg Access
    Going back to the late Linux 2.6 kernel days has been the CONFIG_DMESG_RESTRICT (or for the past number of years, renamed to CONFIG_SECURITY_DMESG_RESTRICT) Kconfig option to restrict access to dmesg in the name of security and not allowing unprivileged users from accessing this system log. While it's been brought up from time to time, Linux distributions are still generally allowing any user access to dmesg even though it may contain information that could help bad actors exploit the system. The primary motivation of CONFIG_SECURITY_DMESG_RESTRICT and an associated sysctl tunable as well (dmesg_restrict) is for restricting access to dmesg so unprivileged users can't see the syslog to avoid possible kernel memory address exposures among other potentially sensitive information that could be leaked about the kernel to help anyone trying to exploit the system. But even with these options being available for years, most Linux distributions leave dmesg open to any user.
  • Is Email Making Professors Stupid?
     

    I can think of at least three strong arguments for why higher education should be that industry, significantly restructuring its work culture to provide professors more uninterrupted time for thinking and teaching, and require less time on email and administrative duties.

  • What is ZIL anyway?
     

    The Infocom ZIL code dump has kicked off a small whirlwind of news articles and blog posts. A lot of them are somewhat hazy on what ZIL is, and how it relates to MDL, Lisp, Z-code, Inform, and the rest of the Golden-Age IF ecosystem.

    So I'm going to talk a lot about it! With examples. But let's go through in chronological order.

  • Death by PowerPoint: the slide that killed seven people

    Edward Tufte’s full report makes for fascinating reading. Since being released in 1987 PowerPoint has grown exponentially to the point where it is now estimated than thirty million PowerPoint presentations are made every day. Yet, PowerPoint is blamed by academics for killing critical thought. Amazon’s CEO Jeff Bezos has banned it from meetings. Typing text on a screen and reading it out loud does not count as teaching. An audience reading text off the screen does not count as learning. Imagine if the engineers had put up a slide with just: “foam strike more than 600 times bigger than test data.” Maybe NASA would have listened. Maybe they wouldn’t have attempted re-entry. Next time you’re asked to give a talk remember Columbia. Don’t just jump to your laptop and write out slides of text. Think about your message. Don’t let that message be lost amongst text. Death by PowerPoint is a real thing. Sometimes literally.
