  • Book Squire Is Ten Years Old

    I choose Python for the first version. I got the logging in, navigating of the Library site and the scraping of account data working as a script. Then decided to built it into an application running under the then new Google App Engine platform. That worked for a while just fine. Over time I added a database to store user information and an email notifications feature with nightly reports delivered when accounts had notable events worth mentioning.

    After working on a few Django applications I decided to move Book Squire to Django and host it on a VPS. Here it stayed for many years working well except for the random updates made to the Library site which broke the parsing of the pages.

    Eventually, the Library upgraded there system in a significant way. Actually made it somewhat user friendly. Still it didn't support multiple cards and you had to click around a bit so Book Squire was reworked and it continued on.

    For my latest update to Book Squire I've rewritten it in Clojure. The latest version is much cleaner internally and suspect the maintenance going forward will be easier. The old Python code did suffer overtime as refactoring was never justified enough because it just worked.

  • Matt Fleming: isolcpus is deprecated, kinda

    A problem that a lot of sysadmins and developers have is, how do you run a single task on a CPU without it being interrupted? It’s a common scenario for real-time and virtualised workloads where any interruption to your task could cause unacceptable latency.

    For example, let’s say you’ve got a virtual machine running with 4 vCPUs, and you want to make sure those vCPU tasks don’t get preempted by other tasks since that would introduce delays into your audio transcoding app.

    Running each of those vCPU tasks on its own host CPU seems like the way to go. All you need to do is choose 4 host CPUs and make sure no other tasks run on them.

    How do you do that?

  • GNU Health HMIS 3.6 Release Candidate 1 is out !

    We are pleased to announce the initial release candidate for the upcoming GNU Health HMIS server !

  • rpminspect-0.7 released, bug fixes and a new integration test suite

    rpminspect-0.7 has been released. The main things in this release are a new integration test suite and many bug fixes. There is one new user feature and that's the -t or --threshold option.

    The -t option lets you control the result code that triggers a non-zero exit code from rpminspect. By default, this is set to VERIFY. But you could set it to BAD or INFO or any other valid result code in the program. The result code specified by this option means that any result in rpminspect at that code or higher will trigger a non-zero return code. Combined with the -T option, this can be a useful tool for some types of CI system integration.

Release of PyPy 7.2

  • PyPy v7.2 released

    As always, this release is 100% compatible with the previous one and fixed several issues and bugs raised by the growing community of PyPy users. We strongly recommend updating.

  • PyPy 7.2 released

    Version 7.2 of PyPy, an implementation of the Python language, is out.

  • PyPy 7.2 Released With Full 64-bit AArch64 Support, PyPy 3.6 Beyond Beta

    PyPy 7.2 is out today as a big update for this alternative Python implementation that currently provides interpreters for compatibility with Python 2.7 and Python 3.6. In cooperation with Arm and Crossbar.io, PyPy developers have been working on complete 64-bit ARM (AArch64) support and this summer they achieved getting the PyPy JIT running on 64-bit ARM. PyPy 7.2 is the first release with this 64-bit ARM support now in good standing.

  • Intel Firmware Binaries Land For AX200/AX201 Bluetooth Linux Support

    With devices beginning to hit store shelves using the new Intel WiFi 6 AX200 series chipsets, the firmware binaries have landed in linux-firmware.git for rounding out support for these latest WiFi/Bluetooth adapters. For a few kernel releases now since earlier this year these new Intel wireless chipsets have been supported by the mainline kernel but the firmware hasn't been part of the de facto linux-firmware.git tree that houses the various firmware binaries for different hardware component support under Linux.

  • Improving distfile mirror structure

    The Gentoo distfile mirror network is essential in distributing sources to our users. It offloads upstream download locations, improves throughput and reliability, guarantees distfile persistency. The current structure of distfile mirrors dates back to 2002. It might have worked well back when we mirrored around 2500 files but it proved not to scale well. Today, mirrors hold almost 70 000 files, and this number has been causing problems for mirror admins.

  • LibreOffice 6.2.7 packages available for Slackware 14.2

    There was a recent update in my repository of LibreOffice packages, but that libreoffice-6.3.2 was just for slackware-current. There’s a recent release in the LibreOffice 6.2 stable series as well (ok… five weeks ago, not that recent…), and so I decided to use my build box’s free weekend to come up with packages for LibreOffice 6.2.7. This release has a security improvement over previous versions, in that it will popup a warning to the user if a document tries to run an embedded script (similar to existing warning mechanism for embedded macros).
