Linux 5.9 RC7

  • Linux 5.9-rc7
    So we finally have all the issues I know about sorted out - the fix
    for the VM issue I mentioned in the rc6 announcement is here, as is
    the fix for the slab corruption issue that was separately discussed,
    along with another silly page locking bug one-liner fix.
    
    But while I do now know of any remaining gating issues any more, the
    fixes came in fairly late. So unless I feel insanely optimistic and/or
    a burning bush tells me that everything is bug-free, my plan right now
    is that I'll do another rc next Sunday rather than the final 5.9
    release. And btw, please no more burning bushes. We're kind of
    sensitive about those on the West coast right now.
    
    Anyway, while the MM side is what kept me on my toes last week, most
    of the changes here are actually drivers and networking. And
    networking drivers. With a small smattering of documentation and
    filesystem fixes and other noise thrown in.
    
    Shortlog appended, but what I really hope you all will do is to give
    it a nice good testing. One extra week or rc kernels will help, but
    only if people actually try this out.
    
    So.. Please?

  • Kernel prepatch 5.9-rc7

    The 5.9-rc7 kernel prepatch is out for testing. "But while I do now know of any remaining gating issues any more, the fixes came in fairly late.

  • Linux 5.9 Stable Expected In Two Weeks, But For Now Is Linux 5.9-rc7

    Linus Torvalds just released Linux 5.9-rc7 as the newest weekly test candidate for Linux 5.9. Due to the regressions encountered this cycle and prominent issues being resolved late, he's looking at releasing Linux 5.9 in two weeks time rather than next week.

  • Joachim Breitner: Learn Haskell on CodeWorld writing Sokoban

    Two years ago, I held the CIS194 minicourse on Haskell at the University of Pennsylvania. In that installment of the course, I changed the first four weeks to teach the basics of Haskell using the online Haskell environment CodeWorld, and lead the students towards implementing the game Sokoban. As it is customary for CIS194, I put my lecture notes and exercises online, and this has been used as a learning resources by people from all over the world. But since I have left the University of Pennsylvania, I lost the ability to update the text, and as the CodeWorld API has evolved, some of the examples and exercises no longer work.

  • SiFive Begins Adding RISC-V "Bullet" Microarchitecture Code To LLVM

    On Friday night patches began to appear for "RISC-V Bullet" in the LLVM compiler code-base. The initial work is on the scheduler being added for the RISC-V Bullet. The initial scheduler is in place for the RISC-V Bullet microarchitecture and bullet-rv32 / bullet-rv64 naming.

  • Pho 1.0, Belated Release

    I was doing some disk housekeeping and noticed that my venerable image viewer, Pho, was at version 1.0pre1, and had been since 2017. It's had only very minimal changes since that time. I guess maybe it's been long enough that it's time to remove that -pre1 moniker, huh?

  • GammaRay 2.11.2

    We have released version 2.11.2 of our Qt application introspection tool GammaRay, bringing support for Qt 5.15 and improved Qt Quick item picking. GammaRay is a software introspection tool for Qt applications developed by KDAB. Leveraging the QObject introspection mechanism it allows you to observe and manipulate your application at runtime. This works both locally on your workstation and remotely on an embedded target.

  • A meta issue for modules: bug tracking

    I was reading a module on meta::cpan when I spied a small issue. I went up to the Issues link, clicked, and was sent to rt.cpan. I know that many module authors now have their modules on sites like GitHub, GitLab, or Bitbucket. Before I posted the issue on rt.cpan, I checked the author's profile for a linked account to one of the other sites. I found the module on GitHub and read the CONTRIBUTING.md to find the author does want issues reported there and not rt.cpan. I did not report my original issue, I reported the link issue instead as it seemed more important. Today is not the first time I noticed this issue with a module's bug tracking. Before continuing, I have not released a module to CPAN and am still learning all that goes into releasing one. Please be gentle if I am wrong or stating an obvious well known fact.

  • Gisle Aas's CPAN distributions are available for adoption

    Gisle Aas (GAAS on CPAN) is a well-known CPAN author, who made his first releases back in 1995. Over the years he has developed and maintained a number of keystone modules that most of us have relied on, whether we realised it or not. Gisle has informed the PAUSE admins that he will no longer be maintaining his CPAN distributions, and is open to responsible adoption. In this blog post we'll summarise what distributions are available, and our interpretation of responsible adoption. If you're interested, please read this post, and if you still would like to adopt a distribution, contact the PAUSE admins (modules at perl dot org) and not Gisle.

  • Firefox Nightly Flips On New JIT "Warp" Code For Greater JavaScript Performance

    Mozilla's SpiderMonkey JavaScript engine team have been working on a big update to their just-in-time compiler code. This big update called "Warp" is now enabled in the latest Firefox Nightly builds for offering big speed-ups. Warp aims to improve the Firefox JavaScript performance by reducing the amount of internal type information that is tracked along with other optimizations. Warp can lead to greater responsiveness and faster page load speed. Numbers cited by Warm developers are normally in the 5~15% range.
