Software: Book Squire, isolcpus, GNU Health and rpminspect

  • 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.

Open source technology, enabling innovation

One of the most exciting projects to come out of the open source revolution is Kubernetes, a tool helping companies running their software on cloud services. It enables them to get the most out of the processing power they’re paying for by identifying machines that are being underutilised. So, if the software detects that a machine is not being optimised, it will load it up with another task so it’s working as hard as it can. Read more

Forbes Raves Upcoming Linux Desktop will enclose Windows 10 and macOS

Forbes senior employee Jason Evangelho dedicated an entire article to an upcoming update for a Sino-domestic Linux distribution: If you haven't paid attention to a bit of Linux desktop distribution called Deepin, it's time to put it on your radar. Remember that Huawei Deepin chose to ship on their MateBook laptop lineup. Remember that Deepin Cloud Sync (for system settings) is a great, progressive feature that every Linux distro must use. Remember that the retractable control center from the future looks like something sexy and sensible. But looking at 2020, Deepin is absolutely breathtaking. This is without a doubt the nicest desktop environment I have ever seen … For me, the UX is more intuitive and pleasant than macOS and Windows 10. And luckily a quick setting can also transform Deepin into the traditional Windows or macOS desktop paradigm's that you are already familiar with. Hell, even the installer is a relief.

[libre-riscv-dev] power pc

So as you know, the RISCV Foundation is seriously impeding progress. There
is huge momentum around RISCV itself, however as far as open *innovation*
is concerned, the sheer arrogance of the Foundation in failing to respect
the combination of Libre goals and business objectives has us completely
isolated from key critical resources such as the closed secret lists and
wiki.

We cannot even get access to documentation explaining how to propose new
extensions.

I have been considering for some time to reach out to MIPS and PowerPC.
Yesterday I wrote to the OpenPower Foundation and was really surprised and
delighted to hear back from Hugh Blemings, whom I worked with over 20 years
ago.

I outlined some conditions (no NDAs, open mailing lists, use of
Certification Marks and Compliance Suites) and he replied back that this
was pretty much along the lines of what they were planning.

I will have a chat with him some time, in the meantime I found the spec:

https://openpowerfoundation.org/?resource_lib=power-isa-version-3-0

It is eeenooormous, however Hugh reassures me that they want to break it
into sections.

Why would we even consider this?

The lesson from RISCV is really clear: if the ISA is set up as a cartel,
Libre innovation is not welcome.

If we had a goal to just *implement* a *pre existing* Extension, there
would be no problem.

It is the fact that we wish to implement entirely new extensions, for CPU
and GPU *and* VPU purposes, but not as a separate processor (which would be
classified as "custom") that is the "problem".

So starting at page 1146, we need to work out how to shoe horn a ton of
stuff into the ISA, as well as fit 16 bit compressed in as well.

Calamares grabs onto things

I’ve been working on Calamares, the Universal Linux Installer, for a little over two years – following up in the role Teo started. It’s used by Neon (for the dev version, not the user version) and Manjaro and lots of other Linux distributions. I’ve typically called it an installer for boutique distro’s, as opposed to the Big Five. Well, Debian 11 has plans. And lubuntu uses it as well (and has for over six months). Those seem pretty big.
