• Zotero and LibreOffice

  If you’re working with LibreOffice and need to create a bibliography, this software makes it simple to manage your citations.

  You can tell how few people use LibreOffice’s Bibliography Database by the fact that a bug that would take 10 minutes to fix has survived since 2002. Instead, those who need bibliographies or citations rely on other software such as Zotero, which can be integrated into LibreOffice with an extension.

  That robust bug is that the Citation Format in the database table is called the Short Name in the input fields. Even more confusing, the examples give an arbitrary name, when to work with the citation insertion tool in Insert | Table of Contents and Index | Insert Bibliography Entry, it should in a standard form, such as (Byfield: 2016) for the MLA format. Add the fact that a single database is used for all files – an absurdity in these memory-rich days – and the neglect of the Bibliography Database is completely understandable.

• PulseCaster 0.9 released!

  For starters, PulseCaster is now ported to Python 3. I used Python 3.6 and Python 3.7 to do the porting. Nothing in the code should be particular to either version, though. But you’ll need to have Python 3 installed to use it, as most Linux bistros do these days.

  Another enhancement is that PulseCaster now relies on the excellent pulsectl library for Python, by George Filipkin and Mike Kazantsev. Hats off to them for doing a great job, which allowed me to remove many, many lines of code from this release.

  Also, due the use of PyGObject3 in this release, there are numerous improvements that make it easier for me to hack on. Silly issues with the GLib mainloop and other entrance/exit stupidity are hopefully a bit better now.

  Also, the code for dealing with temporary files is now a bit less ugly. I still want to do more work on the overall design and interface, and have ideas. I’ve gotten way better at time management since the last series of releases and hope to do some of this over the USA holiday season this late fall and winter (but no promises).

• post modern C tooling - draft

  Some of the C++ people have pulled off one of the cleverest and sneakiest tricks ever. They required 'modern' C99 and C11 features in 'recent' C++ standards. Microsoft has famously still clung onto some 80s version of C with their compiler for the longest time. So it's been a decade of hacks for people writing portable code in C. For a while I thought we'd be stuck in the 80s with C89 forever. However, now that some C99 and C11 features are more widely available in the Microsoft compiler, we can use these features in highly portable code (but forget about C17/C18 ISO/IEC 9899:2018/C2X stuff!!).

• Reading and Writing YAML to a File in Python

  In this tutorial, we're going to learn how to use the YAML library in Python 3. YAML stands for Yet Another Markup Language.

  In recent years it has become very popular for its use in storing data in a serialized manner for configuration files. Since YAML essentially is a data format, the YAML library is quite brief, as the only functionality required of it is the ability to parse YAML formatted files.

  In this article we will start with seeing how data is stored in a YAML file, followed by loading that data into a Python object. Lastly, we will learn how to store a Python object in a YAML file. So, let's begin.

  Before we move further, there are a few prerequisites for this tutorial. You should have a basic understanding of Python's syntax, and/or have done at least beginner level programming experience with some other language. Other than that, the tutorial is quite simple and easy to follow for beginners.

• Python Multiple Inheritance (with Examples)

  In this tutorial, we’ll describe Python Multiple Inheritance concept and explain how to use it in your programs. We’ll also cover multilevel inheritance, the super() function, and focus on the method resolution order.

  In the previous tutorial, we have gone through Python Class and Python (Single) Inheritance. There, you have seen that a child class inherits from a base class. However, Multiple Inheritance is a feature where a class can derive attributes and methods from more than one base classes. Hence, it creates a high level of complexity and ambiguity and known as the diamond problem in the technical world. We’ll be taking up this problem later in this tutorial.

• Adding Methods Retroactively

  Imagine you have a "shapes" library. We have a Circle class, a Square class, etc.

  A Circle has a radius, a Square has a side, and maybe Rectangle has height and width. The library already exists: we do not want to change it.

  However, we do want to add an area calculation. If this was our library, we would just add an area method, so that we can call shape.area(), and not worry about what the shape is.

• Fedora Community Blog: GSoC summer 2019: Fedora Gooey Karma

  The day GSoC projects list was published I started sorting out all the organizations that I’d enjoy working with. Being a Linux user/enthusiast I filtered down to a bunch of Linux distros and desktop managers. Sorting out all the projects, Fedora-Gooey-Karma seemed to be a project that suited the skills I have.

• Linux 5.4 To Fix Many Newer 64-bit Windows Games On Wine / Steam Play

  A kernel patch from CodeWeavers is landing in the Linux 5.4 kernel and will help some 64-bit Windows games run nicely under Wine (and the likes of CrossOver / Valve's Proton) with newer Intel and AMD systems.

  With the few x86 Assembly patches for Linux 5.4 is a UMIP addition by CodeWeavers' Brendan Shanks that ends up being quite important for running a number of Windows games under Proton/Wine on newer AMD/Intel Linux systems.

• You may want to hold off on Linux Kernel 5.3 and systemd 243 if you use a gamepad

  Did you do a big system upgrade recently and notice you're having gamepad issues? You're not alone. Time to downgrade perhaps.

• Bin Li: GUADEC 2019

  Thessaloniki is very peaceful place, every morning I liked to walk along the seaside to the venue. As usual, it was a great and enjoyable GUADEC, thanks to everyone who helped to make it.

• Lunar Vacation Planning

  HPE, one of SUSE’s most important partners in High-Performance Computing and the advancement of science and technology, is now building NASA’s new supercomputer named “Aitken” to support Artemis and future human missions to the moon. HPE’s “Aitken” supercomputer will be built at NASA’s Ames Research Center and will run SUSE Linux Enterprise HPC (co-located where the Pleiades supercomputer – also SUSE-based – has been advancing research for several years). Aitken will run extremely complex simulations for entry, descent and landing on the moon as part of the Artemis program. The missions include landing the next humans on the lunar south polar region by 2024 (on the rim of the Shackleton crater, which experiences constant indirect sunlight for a toasty -300 degrees Fahrenheit).

• Warning Issued For Millions Of Microsoft Windows 10 Users

  The September KB4515384 update is already a menace. Introduced to fix CPU spiking, reports state it has broken Windows 10 search, the Start Menu, Action Centre, USB connections and caused audio problems. And now it is gunning for your Internet access.

  Windows Latest has spotted that users are reporting on Microsoft’s community forum, Windows 10’s Feedback Hub and social networks that network adapters have stopped working after applying this update. Impacted users primarily appear to have Intel chipsets (Asus, MSI and Gigabyte motherboards are mentioned) and both their Ethernet and WiFi connections are affected.

  “Cumulative update (KB4515384) causes the NIC to fail to enable with a code 10 error,” warns one user on the Windows 10 Feedback Hub. “Reinstalling network drivers from Intel or Windows Update sources does not resolve the issue. However removing the update through the ‘Programs & Software’ panel or using a recovery point set *before* the update fully resolves the issue.”

• Google's FS-VERITY File Authentication Called For Inclusion In Linux 5.4 Kernel

  Linux kernel engineer Eric Biggers of Google has sent in a pull request adding FS-VERITY support to the Linux 5.4 but it remains to be seen if Linus Torvalds is content with pulling the code at this stage.

  FS-VERITY is the code Google has been working on for a while now in the context of Android. The focus is on providing transparent integrity/authenticity support for read-only files on an otherwise writable file-system. See this presentation to learn more on this file-based authenticity protection.

• Linux 5.4 Brings Working Temperature Reporting For AMD Ryzen 3000 Series CPUs

  Due to a combination of poor timing and an oversight at AMD, the CPU temperature reporting under Linux for the Ryzen 3000 series processors isn't in order until this new Linux 5.4 cycle. Back at the Ryzen 3000 series launch event I was told everything was "all good" from the Linux support perspective for thermal monitoring, after having been closely following the situation for past Zen CPUs and ended up myself adding the Linux CPU temperature monitoring support for Threadripper 2 among other hudles in the past. That all-good though just ended up meaning that there is no Tcontrol offset needed for these new CPUs, which is great news no longer needing the temperature offset by an arbitrary amount. But the oversight was the Family 17h Model 70h ID was never added to the AMD k10temp driver. As a result, temperature monitoring wasn't actually working and took an extra kernel cycle before this trivial addition landed.

• All about Reactive Foundation,The Linux Foundation's new baby

  The Linux Foundation has announced the launch of the Reactive Foundation, a community of leaders established to accelerate technologies for building the next generation of networked applications. The foundation is made up of Alibaba, Lightbend, Netifi and Pivotal as initial members and includes the successful open source RSocket specification, along with programming language implementations.

  The aim of reactive programming is to build applications that maintain a consistent user experience regardless of traffic on the network, infrastructure performance and different end-user devices (computers, tablets, smartphones). Reactive programming uses a message-driven approach to achieve the resiliency, scalability, and responsiveness that is required for today's networked cloud-native applications, independent of their underlying infrastructure. The Reactive Foundation establishes a formal open governance model and neutral ecosystem for supporting open source reactive programming projects.

GNU Linux-libre 5.3-gnu sources and tarballs are now available at
<http://www.fsfla.org/selibre/linux-libre/download/releases/5.3-gnu/>.
It didn't require any deblobbing changes since -rc7-gnu, the first
published rc-gnu.  Freesh binaries are already available!, thanks to
Jason Self; others are on the way.


Besides recognizing new false positives (sequences that our blob hunter
would report as suspicious, but that are neither blobs nor requests for
blobs), updating the deblobbing scripts for 5.3 required adjusting
cleaned up drivers for updated blob names, recognizing one new Free
piece of firmware with binary and corresponding sources embedded in the
kernel sources, and disabling blob loading introduced in a few drivers:
QCOM, DRM (HDCP), Allegro-DVT, and Meson-VDEC.

This last one was particularly disappointing: the firmware sources were
supposed to be available from LibreELEC, and though the link to the
alleged sources there is broken, I managed to find the "source" repo
containing them, only to find out the "source" was just a binary blob
encoded in C as an array of char, just like Linux used to do back when I
got involved with Linux-libre.  Oh well...  Request disabled...

If anyone can find Freely-licensed actual source code for that, or for
any other file whose loading we disable, please let us know, so that we
can refrain from disabling its loading.

GNU Linux-libre 5.3 Continues Deblobbing & Dealing With Firmware Trickery

WireGuard sadly isn't slated for the now-open Linux 5.4 merge window, but lead developer Jason Donenfeld has put out a new development snapshot of this open-source secure VPN tunnel.

Coming barely two weeks since the previous WireGuard snapshot, this newest development release isn't too heavy on the changes but the focus is on better portability/compatibility.

That's all for now. As always, I love how simple and beautiful GNOME release announcement was. After testing in 3 days, I immediately like this version more than the previous one for the speed improvement and I hope Ubuntu and other distros adopt it soon. Ah, I forgot, regarding Ubuntu, good news for us: next October's Ubuntu Eoan Ermine will feature 3.34! Regarding GNOME, I don't know if this is coincidence or what, but this year's KDE Plasma is faster and smoother and so is GNOME. I think next GNOME 3.36 will be faster and better as well. Finally I would love to say thank you GNOME developers! You all did well in last 6 month.

How do you think about 3.34? Let me know in the comment section!
