Mozilla: Developer Roadshow (Asia Tour), CRLite, Async Interview

  • The Mozilla Developer Roadshow: Asia Tour Retrospective and 2020 Plans

    November 2019 was a busy month for the Mozilla Developer Roadshow, with stops in five Asian cities —Tokyo, Seoul, Taipei, Singapore, and Bangkok. Today, we’re releasing a playlist of the talks presented in Asia. We are extremely pleased to include subtitles for all these talks in languages spoken in the countries on this tour: Japanese, Korean, Chinese, Thai, as well as English. One talk, Hui Jing Chen’s “Making CSS from Good to Great: The Power of Subgrid”, was delivered in Singlish (a Singaporean creole) at the event in Singapore! In addition, because our audiences included non-native English speakers, presenters took care to include local language vocabulary in their talks, wherever applicable, and to speak slowly and clearly. We hope to continue to provide multilingual support for our video content in the future, to increase access for all developers worldwide.

  • CRLite: Speeding Up Secure Browsing

    CRLite pushes bulk certificate revocation information to Firefox users, reducing the need to actively query such information one by one. Additionally this new technology eliminates the privacy leak that individual queries can bring, and does so for the whole Web, not just special parts of it. The first two posts in this series about the newly-added CRLite technology provide background: Introducing CRLite: All of the Web PKI’s revocations, compressed and The End-to-End Design of CRLite. Since mid-December, our pre-release Firefox Nightly users have been evaluating our CRLite system while performing normal web browsing. Gathering information through Firefox Telemetry has allowed us to verify the effectiveness of CRLite.

  • Niko Matsakis: Async Interview #5: Steven Fackler

    Hello! For the latest async interview, I spoke with Steven Fackler (sfackler). sfackler has been involved in Rust for a long time and is a member of the Rust libs team. He is also the author of a lot of crates, most notably tokio-postgres. I particularly wanted to talk to sfackler about the AsyncRead and AsyncWrite traits. These traits are on everybody’s list of “important things to stabilize”, particularly if we want to create more interop between different executors and runtimes. On the other hand, in [tokio-rs/tokio#1744], the tokio project is considering adopting its own variant traits that diverge significantly from those in the futures crate, precisely because they have concerns over the design of the traits as is. This seems like an important area to dig into!

Graphics: Wayland 1.18 Alpha, Linux on Embedded Ryzen with Radeon, and Keith Packard's X Talk

  • wayland 1.17.91
    This is the alpha release for Wayland 1.18. Here's a highlight of the
    biggest changes:
    
    - Add support for the Meson build system (autotools is still supported
      but will be removed in a future release)
    - Add API to tag proxy objects to allow applications and toolkits to
      share the same Wayland connection
    - Track wayland-server timers in user-space to prevent creating too
      many FDs
    - Add wl_global_remove, a new function to mitigate race conditions with
      globals
    
    Thanks to all contributors!

  • Wayland 1.18 Alpha Released With Meson Support, Connection Sharing

    Wayland 1.18 is adding Meson build system support so that Autotools can be dropped in a future release, API support for allowing applications and toolkits to share the same Wayland connection, better handling over file descriptors, and wl_global_remove as a new function for mitigating race conditions with globals. There are also various test improvements, improved documentation, and various other fixes and minor improvements.

  • Linux on Embedded Ryzen with Radeon

    American Micro Devices (AMD) has released the Ryzen processors which works very well with Linux. The embedded processor also contains a Graphical Processing Unit (GPU) which is an AMD Ryzen Vega. The board I am using is the IBase 918f-1605 to install Linux. Linux can be installed from a stock ISO, but the system does not perform as well unless using a special Linux kernel from AMD. It also helps to have the proper GPU driver for performance. Stability is much better with the AMD kernel they provide on their website.

  • Keith Packard Talks About The Early Politics Of X Window System + Code Licensing

    At last week's Linux.Conf.Au conference was an interesting presentation by longtime X developer Keith Packard on the early days of the pre-X.Org X Window System, the collapse of Unix, and how his views formed on copyleft licenses for building thriving communities. Keith's LCA 2020 presentation is focused on the X happenings largely during the 80's and very early 90's. Keith's involvement goes back to the 80's during which he was employed at MIT as part of the X Consortium.

  • Keith Packard: lca2020

    I just got back from linux.conf.au 2020 on Saturday and am still adjusting to being home again. I had the opportunity to give three presentations during the conference and wanted to provide links to the slides and videos.

ODF 1.3 approved as OASIS Committee Specification

OASIS is pleased to announce that Open Document Format for Office Applications (OpenDocument) v1.3 from the OpenDocument TC has been approved as an OASIS Committee Specification. The OpenDocument Format is an open XML-based document file format for office applications, to be used for documents containing text, spreadsheets, charts, and graphical elements. OpenDocument Format v1.3 is an update to the international standard Version 1.2, which was approved by the International Organization for Standardization (ISO) as ISO/IEC 26300 in 2015. OpenDocument Format v1.3 includes improvements for document security, clarifies underspecifications and makes other timely improvements. The OpenDocument Format specifies the characteristics of an open XML-based application-independent and platform-independent digital document file format, as well as the characteristics of software applications which read, write and process such documents. It is applicable to document authoring, editing, viewing, exchange and archiving, including text documents, spreadsheets, presentation graphics, drawings, charts and similar documents commonly used by personal productivity software applications. This Committee Specification is an OASIS deliverable, completed and approved by the TC and fully ready for testing and implementation. Read more
