joshics.in: Why Drupal is the Ultimate CMS for Your Business: Flexibility, Security, and Scalability
When it comes to choosing a Content Management System (CMS) or framework, the options can be overwhelming. WordPress, Joomla, Squarespace, and many others each have their own strengths. However, there's one CMS that stands out among the rest for its power, flexibility, and scalability: Drupal. Here’s why Drupal should be at the top of your list.
Unmatched FlexibilityDrupal is known for its modular architecture, which allows developers to create highly customised solutions. Unlike WordPress and Squarespace that offer limited customisation out of the box, Drupal’s framework enables you to build virtually any type of website, from simple blogs to complex enterprise-level applications. Joomla also offers flexibility, but Drupal surpasses it with its extensive range of modules and themes.
Robust SecuritySecurity is a critical concern for any website owner. While WordPress is often targeted due to its vast user base, and Joomla has had its share of vulnerabilities, Drupal boasts one of the most secure CMS frameworks available. With a dedicated security team that actively works to identify and patch vulnerabilities, Drupal ensures that your site is well-protected against common cyber threats.
ScalabilityOne of the most compelling reasons to choose Drupal is its ability to scale. Whether you're running a small business website or a high-traffic enterprise portal, Drupal can handle your needs. Major websites like NASA trust Drupal to manage their vast amount of content and traffic demands. While WordPress can also scale, it may require significant customisation and optimisations, which come naturally to Drupal.
Active Community SupportDrupal has a large and active community of developers, designers, and contributors who constantly improve the platform. While WordPress boasts the largest community, Drupal’s community-driven approach means you benefit from a wide range of modules, themes, and plugins that can extend the functionality of your site. Joomla also has a strong community, but Drupal’s focus on high-quality, enterprise-level solutions sets it apart.
SEO-FriendlyHaving a website that ranks well on search engines is crucial. Drupal offers extensive SEO capabilities right out of the box, comparable to those of WordPress, which is often praised for its SEO plugins. From clean URLs to meta tags and mobile optimisation, Drupal provides the tools you need to ensure your site is easily discoverable by search engines. This built-in SEO functionality means you can focus more on your content and less on technical tweaks.
Cost-Effective in the Long RunWhile initial development costs for a Drupal site might be higher compared to simpler platforms like WordPress or Squarespace, the long-term benefits make it a cost-effective choice. Its robust architecture reduces the need for frequent redesigns or overhauls, ensuring you get a higher return on investment over time.
Integrated Digital EcosystemFor businesses looking to integrate their website with other digital tools and platforms, Drupal offers seamless integration capabilities. Whether it’s CRM systems, marketing automation tools, or e-commerce platforms, Drupal can easily connect with your existing digital ecosystem, streamlining your operations and enhancing user experience.
if you're looking for a CMS that offers unparalleled flexibility, robust security, scalability, active community support, SEO-friendliness, and long-term cost-effectiveness, Drupal is an excellent choice. Make the smart move and consider Drupal for your next project.
Drupal Drupal CMS Drupal Planet Add new commentHynek Schlawack: Production-ready Python Docker Containers with uv
Starting with 0.3.0, Astral’s uv brought many great features, including support for cross-platform lock files uv.lock. Together with subsequent fixes, it has become Python’s finest workflow tool for my (non-scientific) use cases. Here’s how I build production-ready containers, as fast as possible.
Jonathan Dowland: loading (unintended consequences?)
For their 30th anniversary (ish; the Covid pandemic pushed the date out a bit) British electronic music duo Orbital released the compilation 30 something. The track list mostly looks like a best hits list, which — given their prior compilation celebrating 20 years looks much the same — would appear superfluous. However, they’ve rearranged and re-recorded all their songs for 30, to reflect their live arrangements. The reworkings are sufficiently distinct from the original versions (in some cases I prefer them) and elevate the release. The couple of new tracks are also fun, and many of the remixes on the second disc are worth a listen too.
But what I actually sat down to write about was the cover artwork. They often have designs which riff on the notion of a circle (given their name) and the 30-something art (both for the album and single takes from it) adapts a “loading” spinner-like device from computing (I suppose it mostly closely resembles the spinner from macOS).
A possibly unintended effect of the pattern occurs when you view it on a display which is adjusting its brightness, such as if you’re listening to it on a phone, the screen is off, and you pick it up. The brightest part of the spinner is visible first, and the rest fade into visibility in sequence. The first time you see this is unexpected and very cool. (I've tried to recreate it in the picture below, but I don't think it's worked.)
Although I've suffixed the titled of this post unintended consequences?, It's quite possible this was deliberate.
I’ve got the pattern on a t-shirt and my kids love to call out “Daddy’s loading!” In my convalescence it’s taken on a special sort of resonance because at times I’ve felt I’m in a holding state: waiting for an appointment to be made; waiting a polite interval before chasing an appointment; waiting for treatment to start after attending an appointment. Thankfully I’m at the end of that now, I hope.

Talk Python to Me: #476: Unified Python packaging with uv
Dirk Eddelbuettel: RcppCNPy 0.2.13 on CRAN: Micro Bugfix
Another (again somewhat minor) maintenance release of the RcppCNPy package arrived on CRAN earlier today.
RcppCNPy provides R with read and write access to NumPy files thanks to the cnpy library by Carl Rogers along with Rcpp for the glue to R.
A change in the most recent Rcpp appears to cause void functions wrapper via Rcpp Modules to return NULL, as opposed to being silent. That tickles discrepancy between the current output and the saved (reference) output of one test file, leading CRAN to display a NOTE which we were asked to take care of. Done here in this release—and now that we know we will also look into restoring the prior Rcpp behaviour. Other small changes involved standard maintenance for continuous integration and updates to files README.md and DESCRIPTION. More details are below.
Changes in version 0.2.13 (2024-09-03)A test script was updated to account for the fact that it now returns a few instances of NULL under current Rcpp.
Small package maintenance updates have been made to the README and DESCRIPTION files as well as to the continuous integration setup.
CRANberries also provides a diffstat report for the latest release. As always, feedback is welcome and the best place to start a discussion may be the GitHub issue tickets page.

Brightness controls for all your displays
Whoops, it's already been months since I last blogged. I've been actively involved with Plasma and especially its power management service PowerDevil for over a year now. I'm still learning about how everything fits together.
Turns out though that a little bit of involvement imbues you with just enough knowledge and confidence to review other people's changes as well, so that they can get merged into the next release without sitting in limbo forever. Your favorite weekly blogger for example, Nate Graham, is a force of nature when it comes to responding to proposed changes and finding a way to get them accepted in one form or another. But it doesn't have to take many years of KDE development experience to provide helpful feedback.
Otfen we simply need another pair of eyes trying to understand the inner workings of a proposed feature or fix. If two people think hard about an issue and agree on a solution, chances are good that things are indeed changing for the better. Three or more, even better. I do take pride in my own code, but just as much in pushing excellent improvements like these past the finish line:
- Fabian Arndt's support for Lenovo laptops' battery conservation mode (Plasma 6.1)
- Natalie Clarius's feature to block apps from inhibiting sleep and screen locking (6.2)
- Christoph Wolk's improvements to usability for the Power Management settings page (6.2, one among many of the sort)
- Nate's changes to show the current power profile in addition to the battery charge (6.2)
- Xaver Hugl's push to allow software brightness adjustments not just for HDR displays (6.1), but indeed for any display without hardware brightness controls (6.2)
In turn, responsible developers will review your own changes so we can merge them with confidence. Xaver, Natalie and Nate invested time into getting my big feature merged for Plasma 6.2, which you've already read about:
Per-display Brightness Controls
This was really just a follow-up project to the display support developments mentioned in the last blog post. I felt it had to be done, and it lined up nicely with what KWin's been up to recently.
So how hard could it be to add another slider to your applet? Turns out there are indeed a few challenges.
In KDE, we like to include new features early on and tweak them over time. As opposed to, say, the GNOME community, which tends to discuss them for a loooong time in an attempt to merge the perfect solution on the first try. Both approaches have advantages and drawbacks. Our main drawback is harder to change imperfect code, because it's easy to break functionality for users that already rely on them.
Every piece of code has a set of assumptions embedded into it. When those assumptions don't make sense for the next, improved, hopefully perfect solution (definitely perfect this time around!) then we have to find ways to change our thinking. The code is updated to reflect a more useful set of assumptions, ideally without breaking anyone's apps and desktop. This process is called "refactoring" in software development.
But let's be specific: What assumptions am I actually talking about?
There is one brightness slider for your only displayThis one's obvious. You can use more than just one display at a time. However, our previous code only used to let you read one brightness value, and set one brightness value. For which screen? Well... how about the code just picks something arbitrarily. If you have a laptop with an internal screen, we use that one. If you have no internal screen, but your external monitor supports DDC/CI for brightness controls, we use that one instead.
What's that, you have multiple external monitors that all support DDC/CI? We'll set the same value for all of them! Even if the first one counts from 0 to 100 and the second one from 0 to 10.000! Surely that will work.
No it won't. We only got lucky that most monitors count from 0 to 100.
The solution here is to require all software to treat each display differently. We'll start watching for monitors being connected and disconnected. We tell all the related software about it. Instead of a single set-brightness and a single get-brightness operation, we have one of these per display. When the lower layers require this extra information, software higher up in the stack (for example, a brightness applet) is forced to make better choices about the user experience in each particular case. For example, presenting multiple brightness sliders in the UI.
A popup indicator shows the new brightness when it changesSo this raises new questions. With only one display, we can indicate any brightness change by showing you the new brightness on a percentage bar:
Now you press the "Increase Brightness" key on your keyboard, and multiple monitors are connected. This OSD popup shows up on... your active screen? But did the brightness only change for your active screen, or for all of them? Which monitor is this one popup representing?
Ideally, we'd show a different popup on each screen, with the name of the respective monitor:
That's a good idea! But Plasma's OSD component doesn't have a notion of different popups being shown at the same time on different monitors. It may even take further changes to ask KWin, Plasma's compositor component, about that. What we did for Plasma 6.2 was to provide Plasma's OSD component with all the information it needs to do this eventually. But we haven't implemented our favorite UI yet, instead we hit the 6.2 deadline and pack multiple percentages into a single popup:
That's good enough for now, not the prettiest but always clear. If you only use or adjust one screen, you'll get the original fancy percentage bar you know and love.
The applet can do its own brightness adjustment calculationsYou can increase or decrease brightness by scrolling on the icon of the "Brightness and Color" applet with your mouse wheel or touchpad. Sounds easy to implement: read the brightness for each display, add or subtract a certain percentage, set the brightness again for the same display.
Nope, not that easy.
For starters, we handle brightness key presses in the background service. You'd expect the "Increase Brightness" key to behave the same as scrolling up with your mouse wheel, right? So let's not implement the same thing in two different places. The applet has to say goodbye to its own calculations, and instead we add an interface to background service that the applet can use.
Then again, the background service never had to deal with high-resolution touchpad scrolling. It's so high-resolution that each individual scroll event might be smaller than the number of brightness steps on your screen. The applet contained code to add up all of these tiny changes so that many scroll events taken together will at least make your screen change by one step.
Now the service provides this functionality instead, but it adds up the tiny changes for each screen separately. Not only that, it allows you to keep scrolling even if one of your displays has already hit maximum brightness. When you scroll back afterwards, both displays don't just count down from 100% equally, but the original brightness difference between both screens is preserved. Scroll up and down to your heart's content without messing up your preferred setup.
Dimming will turn down the brightness, then restore the original value laterSimple! Yes? No. As you may guess, we now need to store the original brightness for each display separately so we can restore it later.
But that's not enough: What if you unplug your external screen while it's dimmed? And then you move your mouse pointer again, so the dimming goes away. Your monitor, however, was not there for getting its brightness restored to the original value. Next time you plug it in, it starts out with the dimmed lower brightness as a new baseline, Plasma will gladly dim even further next time.
Full disclosure, this was already an issue in past releases of Plasma and is still an issue. Supporting multiple monitors just makes it more visible. More work is needed to make this scenario bullet-proof as well. We'll have to see if a small and safe enough fix can still be made for Plasma 6.2, or if we'll have to wait until later to address this more comprehensively.
Anyway, these kind of assumptions are what eat up a good amount of development time, as opposed to just adding new functionality. Hopefully users will find the new brightness controls worthwhile.
So let's get to the good newsYour donations allowed KDE e.V. to approve a travel cost subsidy in order to meet other KDE contributors in person and scheme the next steps toward world domination. You know what's coming, I'm going to:
Akademy is starting in just about two days from now! Thank you all for allowing events like this to happen, I'll try to make it count. And while not everyone can get to Germany in person, keep in mind that it's a hybrid conference and especially the weekend talks are always worth watching online. You can still sign up and join the live chat, or take a last-minute weekend trip to Würzburg if you're in the area, or just watch the videos shortly afterwards (I assume they'll go up on the PeerTube Akademy channel).
I'm particularly curious about the outcome of the KDE Goals vote for the upcoming two years, given that I co-drafted a goal proposal this time around. Whether or not it got elected, I haven't forgotten about my promise of working on mouse gesture support on Plasma/Wayland. Somewhat late due to the aforementioned display work taking longer. Other interesting things are starting to happen as well on my end. I'll have to be mindful not to stretch myself too thinly.
Thanks everyone for being kind. I'll be keeping an eye out for your bug reports when the Plasma 6.2 Beta gets released to adventurous testers in just over a week from today.

Samuel Henrique: DebConf24 was fun!: Security, curl, wcurl, Debian's quality
DebConf24 was fun!
A playlist of all of my talks, with subtitles (en, pt-br) and chapters is available on YouTube.
OverviewDebConf24 was held in Busan, South Korea, between Sunday July 28th to Sunday August 4th 2024.
As usual for DebConfs, I had a great time meeting my friends, but also met new people and got to learn a bit about the interesting things they're working on.
I ended up getting too excited during the talk submission stage of the conference and as a result I presented 5 different activities (3 talks, 1 BoF and 1 lightning talk).
Since I was too busy with the presentations, I did not have a lot of time to actually hang out with folks, or even to go out in the city, I guess I've learned my lesson for next time.
The main purpose of this post is to write about all of the things I presented at the conference. I did want to list some of the interesting talks I've watched, but that I would not be able to be fair as I'm sure I would miss some.
You can get the schedule and the recordings of any talks from the conference's website: https://debconf24.debconf.org/schedule/
wcurl Lightning TalkThe most fun of my presentations, during the second-to-last day of the conference, I've asked for help from Sergio Durigan Junior <sergiodj> to setup an URL containing a whitespace and redirecting that to wcurl's manpage.
I then did a little demo to showcase why me (and a lot others) struggle with downloading things with curl, and how wcurl solves that.
Fixing CVEs on Debian: Everything you probably know alreadyI've always felt like DebConf was missing security-related talks, so I decided to do something about it and presented a few of the things I've learned when fixing CVEs for Debian.
This is an area where we don't get a lot of new contributors, I'm trying to change that, and this talk can be used to introduce newcomers to it.
The secret sauce of DebianDebian is not very vocal about all of the nice things it has regarding quality-assurance, testing, or CI, even though it's at the state-of-the-art for a lot of things.
This talk is an initial step towards making people aware of the cool things happening behind the scenes. Ideally we should have it well-documented somewhere.
"I use Debian BTW": fzf, tmux, zoxide and friendsOne of my earliest good memories of Debian was when it started coming with a colored PS1 by default, I still remember the feeling of relief whenever I jumped into a Debian server and didn't have to deal with a black and white PS1.
There's still a lot of room for Debian to ship better defaults, and I think some of them can actually happen.
This talk is a bit of a silly one where I'm just making people aware of the existence of a few Golang/Rust CLI tools, and also some dotfiles configurations that should probably be the default.
curlThe curl project does such a great job with their security advisories that it will likely never receive the amount of praise it deserves, but I did my best at mentioning it throughout my CVEs talk.
Maybe I will write more extensively about this someday, but in case I don't:
There's no other project which always consistently mentions the exact range of commits that are affected by a given CVE.
Forget about whether the versions are EOL, curl doesn't have LTS releases, yet they do such a great job at clearly documenting their CVEs that I would take that over having LTS releases anytime (that's for curl at least, I acknowledge some types of projects have a different need for LTS releases).
Not only that, but they are also always careful about explaining alternative mitigations such as configuration changes, build flags that defuse the exploitation, or parameters that you should not use.
Just like we tend to do every time we meet, me and the other Debian curl maintainers spent the first 2 or 3 days of the conference talking about how we wanted to eventually meet up to discuss the package.
It was going to be informal, maybe during the Cheese and Wine party, but then I've realized we should make it part of the official schedule, which would also give us the recordings for later.
And so the "curl maintainers BoF" happened, where we spoke about HTTP3, GnutTLS, wcurl and other things.
wcurlRight after that BoF, Daniel Stenberg asked if we were interested in having wcurl adopted into curl, which we definitely were, so wcurl is now part of the curl project.
Daniel was also kind enough to design a logo for the project, which makes me especially happy because I can stop with my own approach at a logo (which I had to redo every few days):
And here is the new logo:
Much better, I would say :)
curl SwagDebConf24 was my chance at forwarding some curl swag items to the other curl maintainers, so both Sergio Durigan Junior <sergiodj> and Carlos Henrique Lima Melara <charles> got the curl-up t-shirt and the very cool curl PCB coaster, both gifted by Daniel Stenberg.
Unfortunately I didn't have any of that for DebConf attendees, but I did drop loads of curl stickers at the stickers table, they were gone very quickly.
For the futureI used to think the most humbling experience you could have as someone who presented a talk was to have to watch it yourself, you notice a lot of mistakes and you instantly think about things that should be done differently.
It turns out the most humbling thing to do is actually to write subtitles for your talks, I noticed every single mistake, often multiple times.
So after spending more than 30 hours writing the subtitles for both English and Brazilian Portuguese for my talks, I feel like it's going to be much easier to avoid committing the same mistakes again. After some time you stop feeling shame about those mistakes and you're just left with feelings of annoyance, and at that point it becomes easier to consciously avoid them.
I am collecting a list of things I wish I had done differently on all of those talks, so if I end up presenting any one of them again, it will be an improved version.

GSoC Final Update
This is my last update about my GSoC project (Python bindings for KDE Frameworks).
These weeks have been quieter than usual because I’ve been on vacation, but there are still some new things to share.
I published a mini tutorial on how to generate Python bindings using the new CMake module.
People have started to test the Python bindings and some building issues have been reported (which is good, because that means people have interest in them). Unfortunately I’m going to have less time to contribute as I start university next week, but I’m sure you’ll see me!
Many thanks to Carl (my mentor) and everyone who reviewed my merge requests!

Calligra 4.0.1
Calligra 4.0.1 is out. This small releases mostly contains fixes for distributions issues and updated translations.
I fixed some compatibility issues for Flatpak which is since yesterday available on Flathub.

Yaakov Selkowitz fixed the installation of the Okular generators so now if Calligra is installed, you can read your office document in Okular correctly.
Antonio Rojas dropped the unused KPart dependency and reenabled the user documentations.
I removed the old space navigator plugin which didn’t build anymore and was only used to navigate an office document with some retro controllers.
Finally, I fixed a few issues in Stage, I found while dog footing it for my slides for my Akademy presentation.
