Dries Buytaert announced recently that the product name for the result of the Drupal Starshot Initiative will be Drupal CMS. Exciting! Activities on features for Drupal CMS are divided into tracks - a set of deliverables focused to provide valuable solutions for different parts of the product strategy.

Let’s see what’s cooking in the Drupal CMS kitchen as since the announcement of the track leads, quite some work has been done. We are happy to share a brief overview to highlight the progress made!

The Events Track has been busy with transferring the Events recipe to the Drupal CMS and now we’ve got the beginnings of an event system. As with all the Drupal CMS components, the ultimate plan is for each one to be available as its own project, but at the same time all be developed within the same repo. 

The Data Privacy / Compliance Track is busy developing a survey for the international audience. We are looking forward to sharing it with the community very soon.

The Trial Experience Track in coordination with the Drupal Association has devised a solution to leverage GitLab Pages. After checking in with the rest of the Drupal CMS team, it was decided the trial codebase would be added to the monolithic repository. You can find more details at the dedicated blog post by Matt Glaman.

The Starshot Demo Design System initiative is supporting the Experience Builder demo next month by providing Drupal-branded components within a design system theme. The team has made excellent progress and needs more help in the next two weeks to test components within Experience Builder. Learn how to get involved!

The SEO Track managed to add Basic SEO recipe to Drupal CMS. This recipe will be applied by default, is idempotent (can be applied multiple times), and sets the simple best practices configuration we feel every site needs. The team is continuing to work to define an advanced SEO recipe that we will propose to be optional that has more tools for optimizing for search engines.

The Advanced Search Track has drafted a proposal for the track. It is being reviewed by the leadership team and the idea is to provide a recipe for at least two different approaches and collect community feedback. We expect this to happen in September so stay tuned!

The Media Management Track is undertaking discovery to gather common practices and new insights that will lead to a proposal for the features and recipes for media in early versions of Drupal CMS. The track will also propose how improvements and innovations could look for media beyond the launch of Drupal CMS. Tony Barker has created a survey as part of the discovery and welcomes the community to provide their thoughts and feelings on media in Drupal using this form.

We are observing the progress each track team is making with excitement and will keep you up to date on upcoming developments!

This week was all about catching up on notifications and open PRs from last week, and creating a mega amount of new PRs.

Libtoolers!

The Libtool Team is pleased to announce the release of libtool 2.5.2, a beta release.

This beta release was not planned, but additional testing of a recent bugfix
was requested for distros to have the chance to test it with mass-rebuilds.

The details of this bugfix can be found here:
    https://debbugs.gnu.org/cgi/bugreport.cgi?bug=71489
The commit for this bugfix can be found here:
    https://git.savannah.gnu.org/cgit/libtool.git/commit/?id=0e1b33332429cd578367bd0ad420c065d5caf0ac

I hope to release the stable in a couple of weeks if testing goes well!

GNU Libtool hides the complexity of using shared libraries behind a
consistent, portable interface. GNU Libtool ships with GNU libltdl, which
hides the complexity of loading dynamic runtime libraries (modules)
behind a consistent, portable interface.

PORTLAND, Ore., 29 August 2024—The Drupal Association is pleased to announce Dropsolid as a partner for the Drupal 7 Extended Security Support Provider Program. This initiative aims to support Drupal 7 users by carefully selecting providers that deliver extended security support services beyond the 5 January 2025 end-of-life (EOL) date.

The Drupal 7 Extended Security Support Provider Program allows organizations that cannot migrate from Drupal 7 to newer versions by the EOL date to continue using a version of Drupal 7 that is secure and compliant. This program complements the Association’s Drupal 7 Certified Migration Providers Program, which helps organizations find the right partner to transition their sites from Drupal 7 to Drupal 11.

Dropsolid’s Drupal 7 extended support offers Drupal 7 support beyond 5 January 2024, with Enterprise Drupal specialists with a reputation in the community, access to enterprise Drupal 7 developers to continue development, and much more.

“We’re excited that Dropsolid has stepped up and committed to our Drupal 7 Extended Security Support Program,” commented Tim Doyle, CEO of the Drupal Association.  “Dropsolid has been a tremendous supporter of Drupal and the Drupal Community, and we’re grateful that they’re including bona fide Drupal 7 support among their offerings.” 

As organizations prepare for the transition from Drupal 7, Dropsolid will provide the necessary support to keep their sites secure and operational.

Dominique De Cooman, co-founder and co-CEO of Dropsolid, proudly added: “We are thrilled to qualify for the Drupal 7 Extended Security Support program. Even more so since we're the only European company selected (even though we have offices in US and EU). As an organization of makers contributing towards security of Drupal and Mautic, we want to continue contributing to Drupal as much as possible. It's part of our mission to give Drupal 7 the End of Life it deserves. Beyond EOL support, Dropsolid will continue to deliver robust D7 support at both the code and platform levels. We’re here to back you—past, present, and future.”

Around a decade ago, I was happy to learn about bcache – a Linux block cache system that implements tiered storage (like a pool of hard disks with SSDs for cache) on Linux. At that stage, ZFS on Linux was nowhere close to where it is today, so any progress on gaining more ZFS features in general Linux systems was very welcome. These days we care a bit less about tiered storage, since any cost benefit in using anything else than nvme tends to quickly evaporate compared to time you eventually lose on it.

In 2015, it was announced that bcache would grow into its own filesystem. This was particularly exciting and it caused quite a buzz in the Linux community, because it brought along with it more features that compare with ZFS (and also btrfs), including built-in compression, built-in encryption, check-summing and RAID implementations.

Unlike ZFS, it didn’t have a dkms module, so if you wanted to test bcachefs back then, you’d have to pull the entire upstream bcachefs kernel source tree and compile it. Not ideal, but for a promise of a new, shiny, full-featured filesystem, it was worth it.

In 2019, it seemed that the time has come for bcachefs to be merged into Linux, so I thought that it’s about time we have the userspace tools (bcachefs-tools) packaged in Debian. Even if the Debian kernel wouldn’t have it yet by the time the bullseye (Debian 11) release happened, it might still have been useful for a future backported kernel or users who roll their own.

By total coincidence, the first git snapshot that I got into Debian (version 0.1+git20190829.aa2a42b) was committed exactly 5 years ago today.

It was quite easy to package it, since it was written in C and shipped with a makefile that just worked, and it made it past NEW into unstable in 19 January 2020, just as I was about to head off to FOSDEM as the pandemic started, but that’s of course a whole other story.

Fast-forwarding towards the end of 2023, version 1.2 shipped with some utilities written in Rust, this caused a little delay, since I wasn’t at all familiar with Rust packaging yet, so I shipped an update that didn’t yet include those utilities, and saw this as an opportunity to learn more about how the Rust eco-system worked and Rust in Debian.

So, back in April the Rust dependencies for bcachefs-tools in Debian didn’t at all match the build requirements. I got some help from the Rust team who says that the common practice is to relax the dependencies of Rust software so that it builds in Debian. So errno, which needed the exact version 0.2, was relaxed so that it could build with version 0.4 in Debian, udev 0.7 was relaxed for 0.8 in Debian, memoffset from 0.8.5 to 0.6.5, paste from 1.0.11 to 1.08 and bindgen from 0.69.9 to 0.66.

I found this a bit disturbing, but it seems that some Rust people have lots of confidence that if something builds, it will run fine. And at least it did build, and the resulting binaries did work, although I’m personally still not very comfortable or confident about this approach (perhaps that might change as I learn more about Rust).

With that in mind, at this point you may wonder how any distribution could sanely package this. The problem is that they can’t. Fedora and other distributions with stable releases take a similar approach to what we’ve done in Debian, while distributions with much more relaxed policies (like Arch) include all the dependencies as they are vendored upstream.

As it stands now, bcachefs-tools is impossible to maintain in Debian stable. While my primary concerns when packaging, are for Debian unstable and the next stable release, I also keep in mind people who have to support these packages long after I stopped caring about them (like Freexian who does LTS support for Debian or Canonical who has long-term Ubuntu support, and probably other organisations that I’ve never even heard of yet). And of course, if bcachfs-tools don’t have any usable stable releases, it doesn’t have any LTS releases either, so anyone who needs to support bcachefs-tools long-term has to carry the support burden on their own, and if they bundle it’s dependencies, then those as well.

I’ll admit that I don’t have any solution for fixing this. I suppose if I were upstream I might look into the possibility of at least supporting a larger range of recent dependencies (usually easy enough if you don’t hop onto the newest features right away) so that distributions with stable releases only need to concern themselves with providing some minimum recent versions, but even if that could work, the upstream author is 100% against any solution other than vendoring all its dependencies with the utility and insisting that it must only be built using these bundled dependencies. I’ve made 6 uploads for this package so far this year, but still I constantly get complaints that it’s out of date and that it’s ancient. If a piece of software is considered so old that it’s useless by the time it’s been published for two or three months, then there’s no way it can survive even a usual stable release cycle, nevermind any kind of long-term support.

With this in mind (not even considering some hostile emails that I recently received from the upstream developer or his public rants on lkml and reddit), I decided to remove bcachefs-tools from Debian completely. Although after discussing this with another DD, I was convinced to orphan it instead, which I have now done. I made an upload to experimental so that it’s still available if someone wants to work on it (without having to go through NEW again), it’s been removed from unstable so that it doesn’t migrate to testing, and the ancient (especially by bcachefs-tools standards) versions that are in stable and oldstable will be removed too, since they are very likely to cause damage with any recent kernel versions that support bcachefs.

And so, my adventure with bcachefs-tools comes to an end. I’d advise that if you consider using bcachefs for any kind of production use in the near future, you first consider how supportable it is long-term, and whether there’s really anyone at all that is succeeding in providing stable support for it.

The first prominent leap forward this week was built by Harumi “hooroomoo” Jang: they added the ability to Experience Builder (XB) to first pick the location to add a component to, and then pick the component, rather than only the other way around:

Hovering a section (XB calls top-level components sections) now offers placing another section and triggers the component list form.
Issue #3460952, image by Harumi.

Clearly, it’s important to support both paths towards placing a component!

Great news: this week, Bálint “balintbrews” Kléri joined the team working on XB full-time :) Satisfyingly, he landed an improvement that he started working on as a volunteer contributor: #3458535: Middle click + drag doesn’t work correctly if middle click is inside preview iframe.

Utkarsh “utkarsh_33”, syeda-farheen, Harumi and Jesse “jessebaker” Baker fixed the undo/redo functionality and added end-to-end tests, ensuring that XB cannot regress anymore on that essential functionality.

Ben “bnjmnm” Mullins and I collaborated to overhaul XB’s all-props test-only Single-Directory Component (SDC), whose purpose is solely to exercise the full spectrum of prop shapes (JSON schemas) that SDC can use:

The all-props test-only SDC facilitates testing/developing missing pieces of XB: it makes it easy to see the editing UX that is generated for a particular SDC prop shape.
Issue #3463583, image by Wim.

Last week, we landed component previews, and that was a big leap forward! We firmly believe in rapid iteration, and landing something as soon as it’s at least partially usable, rather than polishing it to perfection — for a mature codebase like Drupal core that makes sense, but not for something that is still in its infancy, like XB. So, unsurprisingly, we found an (obvious) bug: the preview caused styles to bleed:

Notice how pink outlines appear everywhere as soon as the Hero component is previewed — that’s obviously not the intent! :D
Issue #3466303, image by Jesse.

Jesse, Utkarsh and Gaurav “gauravvvv” used shadow DOM to properly encapsulate this.

OpenAPI: constantly keeping front-end and back-end work in sync

Back during week 3, Lee “larowlan” Rowlands opened an issue to create an OpenAPI spec for the (then) mock HTTP responses. Back then, the client (React, JS) and server (PHP, Drupal module) were being developed completely independently. Because things were still moving so rapidly back then, some request or response shape was changing almost daily, and nobody had OpenAPI experience … it sadly didn’t become a priority.

then, in the past ~5 or so weeks, having an OpenAPI spec that both the mocks and the actual server responses were validated against would have prevented several problems, and would have boosted productivity.

Thankfully, Philip “pfrilling” Frilling had already gotten significant parts working (and he was able to reuse Lee’s work on the Decoupled Layout Builder API module!). It was not yet mergeable because it didn’t validate the actual server responses yet.
So I started pushing it forward and ran into PHP dependency hell, was able to fix that, and then got us onto OpenAPI 3.1.0 (instead of 3.0.0), enabling XB’s openapi.yml to use patternProperties, without which we actually cannot express all of XB’s response shapes.

Hurray! A whole class of productivity blockers gone! (And Lee was right all along, of course.)

Shape matching woes

Last week’s StorablePropShape worked okay, but Ted “tedbow” Bowman’s work on #3446722: Introduce an example set of representative SDC components; transition from “component list” to “component tree” revealed an interesting edge case: JSON object keys are always strings, so 50 is encoded as '50', meaning … the type is changed, and information is lost. Fortunately, Drupal core solved this a decade ago: we (re)discovered Drupal core’s ::storageSettingsFromConfigData(), which was added for precisely this purpose! A simple fix by Utkarsh “utkarsh_33” later, and we were good to go :)

That wasn’t the only problem #3446722 surfaced: we figured out why exactly the JSON schema validation refused to accept a sample value generated by Drupal core’s uri field type … and it turns out that’s simply because that field type indeed generates invalid URIs! We worked around it by swapping the class and overriding the logic to generate valid sample values. 1

In other words: matching the SDC props’ type information (expressed as JSON schema) against Drupal’s Typed Data/Entity/Field/Field Property type information (expressed as DataType plugins + validation constraints) is definitely revealing interesting problems that probably nobody else has been running into :D

P.S.: we set a new record by a significant margin this week: 16 MRs merged!

Week 13 was August 5–11, 2024.

1. We’ll eventually create upstream issues in Drupal core, but first we’re working accumulating a range of these kinds of problems, to identify the best strategy to fix this upstream. We’re now at ten overrides for field type classes, for a variety of reasons — most for missing validation constraints and/or incorrect field property class implementations. ↩︎

The PyPy project is always happy to hear about industrial use and deployments of PyPy. For the GC bug finding task earlier this year, we collaborated with PortaOne and we're super happy that Serhii Titov, head of the QA department at PortaOne, was up to writing this guest post to describe their use and experience with the project.

What does PortaOne do?

We at PortaOne Inc. allow telecom operators to launch new services (or provide existing services more efficiently) using our VoIP platform (PortaSIP) and our real-time charging system (PortaBilling), which provides additional features for cloud PBX, such as call transfer, queues, interactive voice response (IVR) and more. At this moment our support team manages several thousand servers with our software installed in 100 countries, through which over 500 telecommunication service providers connect millions of end users every day. The unique thing about PortaOne is that we supply the source code of our product to our customers - something unheard of in the telecom world! Thus we attract "telco innovators", who use our APIs to build around the system and the source code to create unique tweaks of functionality, which produces amazing products.

At the core of PortaSIP is the middle-ware component (the proper name for it is "B2BUA", but that probably does not say much to anyone outside of experts in VoIP), which implements the actual handling of SIP calls, messages, etc. and all added features (for instance, trying to send a call via telco operators through which the cost per minute is lower). It has to be fast (since even a small delay in establishing a call is noticed by a customer), reliable (everyone hates when a call drops or cannot be completed) and yet easily expandable with new functionality. This is why we decided to use Python as opposed to C/C++ or similar programming languages, which are often used in telecom equipment.

The B2BUA component is a batch of similar Python processes that are looped inside a asyncore.dispatcher wrapper. The load balancing between these Python processes is done by our stateless SIP proxy server written in C++. All our sockets are served by this B2BUA. We have our custom client-wrappers around pymysql, redis, cassandra-driver and requests to communicate with external services. Some of the Python processes use cffi wrappers around C-code to improve their performance (examples: an Oracle DB driver, a client to a radius server, a custom C logger).

The I/O operations that block the main thread of the Python processes are processed in sub-threads. We have custom wrappers around threading.Thread and also asyncore.dispatcher. The results of such operations are returned to the main thread.

Improving our performance with PyPy

We started with CPython and then in 2014 switched to PyPy because it was faster. Here's an exact quote from our first testing notes: "PyPy gives significant performance boost, ~50%". Nowadays, after years of changes in all the software involved, PyPy still gives us +50% boost compared to CPython.

Taking care of real time traffic for so many people around the globe is something we're really proud of. I hope the PyPy team can be proud of it as well, as the PyPy product is a part of this solution.

Finding a garbage collector bug: stage 1, the GC hooks

However our path with PyPy wasn't perfectly smooth. There were very rare cases of crashes on PyPy that we weren't able to catch. That's because to make coredump useful we needed to switch to PyPy with debug, but we cannot let it run in that mode on a production system for an extended period of time, and we did not have any STR (steps-to-reproduce) to make PyPy crash again in our lab. That's why we kept (and still keep) both interpreters installed just in case, and we would switch to CPython if we noticed it happening.

At the time of updating PyPy from 3.5 to 3.6 our QA started noticing those crashes more often, but we still had no luck with STR or collecting proper coredumps with debug symbols. Then it became even worse after our development played with the Garbage Collector's options to increase performance of our middleware component. The crashes started to affect our regular performance testing (controlled by QA manager Yevhenii Bovda). At that point it was decided that we can no longer live like that and so we started an intense investigation.

During the first stage of our investigation (following the best practice of troubleshooting) we narrowed down the issue as much as we could. So, it was not our code, it was definitely somewhere in PyPy. Eventually our SIP software engineer Yevhenii Yatchenko found out that this bug is connected with the use of our custom hooks in the GC. Yevhenii created ticket #4899 and within 2-3 days we got a fix from a member of the PyPy team, in true open-source fashion.

Finding a garbage collector bug: stage 2, the real bug

Then came stage 2. In parallel with the previous ticket, Yevhenii created #4900 that we still see failing with coredumps quite often, and they are not connected to GC custom hooks. In a nutshell, it took us dozens of back and forward emails, three Zoom sessions and four versions of a patch to solve the issue. During the last iteration we got a new set of options to try and a new version of the patch. Surprisingly, that helped! What a relief! So, the next logical step was to remove all debug options and run PyPy only with the patch. Unfortunately, it started to fail again and we came to the obvious conclusion that what will help us is not a patch, but one of options we were testing out. At that point we found out that PYPY_GC_MAX_PINNED=0 is a necessary and sufficient condition to solve our issue. This points to another bug in the garbage collector, somehow related to object pinning.

Here's our current state: we have to add PYPY_GC_MAX_PINNED=0, but we do not face the crashes anymore.

Conclusion and next steps

Gratitude is extended to Carl for his invaluable assistance in resolving the nasty bugss, because it seems we're the only ones who suffered from the last one and we really did not want to fall back to CPython due to its performance disadvantage.

Serhii Titov, head of the QA department at PortaOne Inc.

P.S. If you are a perfectionist and at this point you have mixed feelings and you are still bothered by the question "But there might still be a bug in the GC, what about that?" - Carl has some ideas about it and he will sort it out (we will help with the testing/verification part).

Desktop software has many differences from mobile and embedded applications but one of the biggest and most obvious is the screen. How can you take advantage of all that real estate for your application? Here are six considerations for managing the screen in your desktop application.

1. Choosing the right GUI framework

Use a flexible GUI framework that easily supports building apps with differing resolutions. The less hand-tweaking you need for your dialogs, graphical assets, and interface across a wide spectrum of resolutions, the better.

2. Testing across diverse displays

Make sure you have a wide range of monitors to test your app against. It’s easy to assume everything works perfectly when your app is tested on a uniform configuration provided by IT. However, visual issues may arise when your app runs on smaller, larger, or different monitors.

3. Setting clear resolution standards

Set a clear minimum resolution that supports your application’s features effectively. Ensure all dialogs fit on screen, scrollbars function properly, nothing is off-screen. Also, test against ultra-high-resolution monitors (like 4K and 8K) to ensure clarity and usability at high DPI settings. Verify that text is legible, controls are noticeable, and clickable regions are big enough to target accurately.

4. Designing for adaptability

Ensure that your application’s user interface is not only scalable but also adaptable. It should reconfigure itself based on the resolution, maintaining a balance between functionality and aesthetics. Dialog boxes should be resizable, and layout managers should dynamically adjust component placement based on the available screen real estate.

5. Embracing multi-monitor flexibility

Multi-monitor setups aren’t just for developers anymore. Many people use laptops along with a larger monitor. In fact, a two-screen configuration may be even more popular than single screens. Make sure your application handles this flexibility intelligently by allowing spawning windows or panels that can be moved to the monitor that best works for the user.

6. Customizing the user workspace

With features such as dockable toolbars, multiple document interfaces, or floating inspectors, you can allow users to customize their workspace. This is particularly handy for apps like graphic design, audio/video editing, and software development, where distributing a wide variety of tools, dialogs, controls, and views across the entire screen real estate is essential.

Final thoughts

Designing and testing for multiple screen resolutions and configurations is part of making a great application. As screen technology evolves and user expectations rise, your applications’ ability to harness the full potential of ultra resolution and multi-monitor setups might just set it apart from the crowd.

Why do we ask for donations so often? Because it’s important! As KDE becomes more successful and an increasing number of people use our software, our costs grow as well:

• Web and server hosting
• Organizing and hosting larger Akademy events
• Funding more and larger sprints
• Paying people to work on stuff the volunteer community doesn’t focus on, and retaining them over time

And so on. If we don’t raise more money while our software becomes more popular, we risk “dying of success,” so to speak. Remember, we give all this stuff away for free, no strings attached! Nobody has to pay a cent if they don’t want to or can’t afford to.

Accordingly, if you’re plugged into KDE social media, you probably see a lot of requests for donations. I end every one of my “This Week in KDE” posts with one, and many others do for their own blog posts as well. KDE’s official social media channels blast it out constantly, and we also do yearly fundraisers that are widely promoted online. If you’re reading this, you may get the impression that we’re always begging for cash!

But if you’re not plugged into these communications channels, you might not have ever seen a donation request at all. We know that the fraction of people who subscribe to these channels is small, so there’s a huge number of people who may not even know they can donate to KDE, let alone that donations are critically important to its continued existence.

Starting in Plasma 6.2, that changes, and I’d like to introduce what it will look like! From 6.2 onwards, Plasma itself will show a system notification asking for a donation once per year, in December:

The idea here is to get the message that KDE really does need your financial help in front of more eyeballs — especially eyeballs not currently looking at KDE’s public-facing promotion efforts.

Now, I know that messages like this can be controversial! The change was carefully considered, and we tried our best to minimize the annoying-ness factor: It’s small and unobtrusive, and no matter what you do with it (click any button, close it, etc) it’ll go away until next year. It’s implemented as a KDE Daemon (KDED) module, which allows users and distributors to permanently disable it if they like. You can also disable just the popup on System Settings’ Notifications page, accessible from the configure button in the notification’s header.

Ultimately the decision to do this came down to the following factors:

1. We looked at FOSS peers like Thunderbird and Wikipedia which have similar things (and in Wikipedia’s case, the message is vastly more intrusive and naggy). In both cases, it didn’t drive everyone away and instead instead resulted in a massive increase in donations that the projects have been able to use to employ lots of people.
2. KDE really needs something like this to help our finances grow sustainably in line with our userbase and adoption by vendors and distributors.

So now let me address what I anticipate will be some common concerns:

I think you’re wrong; people hate pop-ups and this is going to turn them off!

Like I said, peer organizations didn’t see that happen, and some were even more in-your-face about it. I do suspect a small but vocal crowd of people will spread doom and gloom about it on social media anyway, of course. This also happened when we implemented off-by-default telemetry — which by the way, was implemented so conservatively that it barely collects any information of value at all. It’s a cautionary tale about the danger of being too timid and ending up with the worst of both worlds.

The worst-case scenario is that we don’t get more donations from this after a couple of years, and end up removing it. That’s always an option. But I think it’s worth venturing out there and being a bit bold! With risk comes opportunity.

KDE shouldn’t need to pay people directly; employment should come from vendors and distributors shipping our software!

To a certain extent this already does happen: by far the largest contributor of paid work is Blue Systems — mostly funded by Valve Corporation, which ships KDE software on the Steam Deck. There are also trickles and spurts of sponsored work from distros, KDAB, and enterprising folks who get funded via grants.

Ultimately a healthy economic ecosystem around KDE includes people employed by many parties, including KDE itself, in my opinion. This is how KDE can help control its own destiny. And that costs money! Money that needs to come from somewhere.

Why does it have to be a notification pop-up? Put this in Welcome Center or something!

We had a request for donations in Welcome center for several years, and it didn’t make a difference, because right after you’ve installed the system wasn’t the right time to ask. At that point, you don’t know if you like Plasma yet, so asking for money is premature.

If KDE is as successful as Thunderbird and Wikipedia have been, what are you going to do with all that money?

This is a question the KDE e.V. board of directors as a whole would need to answer, and any decision on it will be made collectively.

But as one of the five members on that board, I can tell you my personal answer and the one that as your representative, I’d advocate for. It’s basically the platform I ran on two years ago: extend an offer of full-time employment to our current people, and hire even more! I want us to end up with paid QA people and distro developers, and even more software engineers. I want us to fund the creation of a next-generation KDE OS we can offer directly to institutions looking to switch to Linux, and a hardware certification program to go along with it. I want us to to extend our promotional activities and outreach to other major distros and vendors and pitch our software to them directly. I want to see Ubuntu, Red Hat Enterprise Linux, and SUSE Linux Enterprise Desktop ship Plasma by default. I want us to use this money to take over the world — with freedom, empowerment, and kindness.

These have been dreams for a long time, and throughout KDE we’ve been slowly moving towards them over the years. With a lot more money, we can turbocharge the pace! If that stuff sounds good, you can start with a donation today.

I know talking about money can be awkward. But failure to plan is planning to fail; money is something we can’t ignore and just hope things work out — and we don’t. Raising more money is a part of that plan, and this new yearly donation notification is a part of raising money. It’s my expectation and hope that asking our users for donations will result in more donations, and that we can use these to accelerate KDE’s reach and the quality of our software!

Drupal core development offers developers both opportunities and challenges. On the one hand, it keeps them updated with the latest API changes, ensures their skills stay sharp, introduces fresh ideas and solutions by reviewing contributions from other smart developers and helps developers optimize their code for various scenarios they might not have considered before. On the other hand, getting into Drupal development isn’t easy. Setting up Drupal correctly requires attention to detail and understanding its setup.

A few weeks ago Tiziano Bacocco started a small project to implement a (golang) proxy that allows to store proxmox backups on S3 compatible storage: pmoxs3backuproxy, a feature which the current backup server does not have.

I wanted to have a look at the Proxmox Backup Server implementation for a while, so i jumped on the wagon and helped with adding most of the API endpoints required to seamlessly use it as drop-in replacement in PVE.

The current version can be configured as storage backend in PVE. You can then schedule your backups to the S3 storage likewise.

It now supports both the Fixed index format required to create virtual machine backups and the Dynamic index format, used by the regular proxmox-backup-client for file and container backups. (full and incremental)

The other endpoints like adding notes, removing or protecting backups, mounting images using the PVE frontend (or proxmox-backup-client) work too. It comes with a garbage collector that does prune the backup storage if snapshots expire and runs integrity checks on the data.

You can also configure it as so called “remote” storage in the Proxmox Backup server itself and pull back complete buckets using “proxmox-backup-manager pull”, if your local datastore crashes.

I think it will become more interesting if future proxmox versions will allow to push backups to other stores, too.

We are happy to announce the release of GNU Taler v0.13.

GNUnet 0.22.0 released

We are pleased to announce the release of GNUnet 0.22.0.
GNUnet is an alternative network stack for building secure, decentralized and privacy-preserving distributed applications. Our goal is to replace the old insecure Internet protocol stack. Starting from an application for secure publication of files, it has grown to include all kinds of basic protocol components and applications towards the creation of a GNU internet.

This is a new major release. It breaks protocol compatibility with the 0.21.x versions. Please be aware that Git master is thus henceforth (and has been for a while) INCOMPATIBLE with the 0.21.x GNUnet network, and interactions between old and new peers will result in issues. In terms of usability, users should be aware that there are still a number of known open issues in particular with respect to ease of use, but also some critical privacy issues especially for mobile users. Also, the nascent network is tiny and thus unlikely to provide good anonymity or extensive amounts of interesting information. As a result, the 0.22.0 release is still only suitable for early adopters with some reasonable pain tolerance .

We Updated the Drupal User Guide for Drupal 11

Drupal 11 was released recently. Yay. And with it comes a bunch of minor (and sometimes major) changes to the way Drupal works and the need to update the documentation to reflect those changes.
