LostCarPark Drupal Blog: Drupal Advent Calendar day 20 - Navigation
It’s day 20 of the Drupal Advent Calendar, and today we’re looking at the admin UI Navigation. Joining us today are Pablo López and Matthew Oliveira, so let’s look into it…
The aim of the Navigation track is to provide a better site management experience for Drupal users. It does not provide a specific recipe or feature to Drupal CMS. Navigation is a core experimental module. However, the Navigation track provides key integration points to Drupal CMS that will help other tracks to highlight their features in the new Navigation left sidebar.
The navigation sidebar provides an improved interface for site builders and content creatorsSince Navigation has replaced Toolbar in Drupal CMS…

New LabPlot User Documentation
In recent weeks we have been working on transferring LabPlot’s documentation to a new format.
We decided to move the documentation from the DocBook and MediaWiki format to the Sphinx/reStrcutredText framework. In our perception Sphinx offers a user-friendly and flexible way to create and manage documentation. Easy math typing and code formatting also come along. Additionally, Sphinx supports basic syntax checks, and modern documentation practices, such as versioning and integration with various output formats like HTML, PDF and ePub.
The new user’s manual is available on a dedicated page: https://docs.labplot.org. Please check it out and let us know what you think.
The manual still needs to be supplemented with new content, so we encourage you to contribute to the documentation, e.g. by fixing and adding new sections, updating images, as collaborative efforts can lead to a more comprehensive resource for everyone. Please check the Git repository dedicated to the documentation to find more details on how to help make it better.

Digging into the Fast Sketch Cleanup Plugin for Krita
We started this project with the intent of providing users a tool helpful in inking sketches. It is based on a research article by Simo & Sierra published in 2016, and it uses neural networks (now commonly called simply AI) to work. The tool has been developed in partnership with Intel and it’s still considered experimental, but you can already use it and see the results.
In the section below there are some real life examples of use cases and the results from the plugin. The results vary, but it can be used for extracting faint pencil sketches from photos, cleaning up lines, and comic book inking.
Regarding the model used in the tool, we trained it ourselves. All the data in the dataset is donated from people who sent their pictures to us themselves and agreed on this specific use case. We haven’t used any other data. Moreover, when you use the plugin, it processes locally on your machine, it doesn’t require any internet connection, doesn’t connect to any server, and no account is required either. Currently it works only on Windows and Linux, but we’ll work on making it available on MacOS as well.
Use casesIt averages the lines into one line and creates strong black lines, but the end result can be blurry or uneven. In many cases however it still works better than just using a Levels filter (for example in extracting the pencil sketch). it might be a good idea to use Levels filter after using the plugin to reduce the blurriness. Since the plugin works best with white canvas and grey-black lines, in case of photographed pencil sketches or very light sketch lines, it might be a good idea to use Levels also before using the plugin.
Extracting photographed pencil sketchThis is the result of the standard procedure of using Levels filter on a sketch to extract the lines (which results in a part of the image getting the shadow):

The sketch was drawn by Tiar (link to KA profile)
This is the procedure using the plugin with SketchyModel (Levels → plugin → Levels):

Comparison (for black lines):
sketch_girl_procedures_comparison_small1920×1260 215 KB
Another possible result is to just stop at the plugin without forcing black lines using Levels, which results in a nicer, more pencil-y look while keeping the lower part of the page still blank:

Here in the pictures above you can see the comic book style inking. The result, which is a bit blurry compared to the original, can be further enhanced by using a Sharpen filter. The dragon was sketched by David Revoy (CC-BY 4.0).

On the pictures below, on the scales of the fish, you can see how the model discriminates lighter lines and enhances the stronger lines, making the scales more pronounced. In theory you could do that using the Levels filter, but in practice the results would be worse, because the model takes into account local strength of the line.

How to use it in KritaTo use the Fast Sketch Cleanup plugin in Krita, do the following:
-
Prepare Krita:
-
On Windows:
-
Either in one package: download Krita 5.3.0-prealpha with Fast Sketch Cleanup plugin already included: https://download.kde.org/unstable/krita/5.3.0-prealpha-fast-sketch/krita-x64-5.3.0-prealpha-cdac9c31.zip
-
Or separately:
- Download portable version of Krita 5.2.6 (or similar version - should still work)
- Download separately the Fast Sketch Cleanup plugin here: https://download.kde.org/stable/krita/FastSketchPlugin-1.0.2/FastSketchPlugin1.0.2.zip
- Unzip the file into krita-5.2.6/ folder (keeping the folder structure).
- Then go to Settings → Configure Krita → Python Plugin Manager, enable Fast Sketch Cleanup plugin, and restart Krita.
-
-
On Linux:
- Download the appimage: https://download.kde.org/unstable/krita/5.3.0-prealpha-fast-sketch/krita-5.3.0-prealpha-cdac9c31c9-x86_64.AppImage
-
-
(Optional) Install NPU drivers if you have NPU on your device (practically only necessary on Linux, if you have a very new Intel CPU): Configurations for Intel® NPU with OpenVINO™ — OpenVINO™ documentation (note: you can still run the plugin on CPU or GPU, it doesn’t require NPU)
-
Run the plugin:
- Open or create a white canvas with grey-white strokes (note that the plugin will take the current projection of the canvas, not the current layer).
- Go to Tools → Fast Sketch Cleanup
- Select the model. Advanced Options will be automatically selected for you.
- Wait until it finishes processing (the dialog will close automatically then).
- See that it created a new layer with the result.
Currently it’s better to just use the SketchyModel.xml, in most cases it works significantly better than the SmoothModel.xml.
You need to make sure the background is pretty bright, and the lines you want to keep in the result are relatively dark (either somewhat dark grey or black; light grey might result in many missed lines). It might be a good idea to use a filter like Levels beforehand.
After processing, you might want to enhance the results with either Levels filter or Sharpen filter, depending on your results.
Technology & Science behind it Unique requirementsFirst unique requirement was that it had to work on canvases of all sizes. That meant that the network couldn’t have any dense/fully or densely connected linear layers that are very common in most of the image processing neural networks (which require input of a specific size and will produce different results for the same pixel depending on its location), only convolutions or pooling or similar layers that were producing the same results for every pixel of the canvas, no matter the location. Fortunately, the Simo & Sierra paper published in 2016 described a network just like that.
Another challenge was that we couldn’t really use the model they created, since it wasn’t compatible with Krita’s license, and we couldn’t even really use the exact model type they described, because one of those model files would be nearly as big as Krita, and the training would take a really long time. We needed something that would work just as well if not better, but small enough that it can be added to Krita without making it twice as big. (In theory, we could do like some other companies and make the processing happen on some kind of a server, but that wasn’t what we wanted. And even if it resolved some of our issues, it would provide plenty of its own major challenges. Also, we wanted for our users to be able to use it locally without a reliance on our servers and the internet). Moreover, the model had to be reasonably fast and also modest in regards to RAM/VRAM consumption.
Moreover, we didn’t have any dataset we could use. Simo & Sierra used a dataset, where the expected images were all drawn using a constant line width and transparency, which meant that the results of the training had those qualities too. We wanted something that looked a bit more hand-drawn, with varying line-width or semi-transparent ends of the lines, so our dataset had to contain those kinds of images. Since we haven’t been aware of any datasets that would match our requirements regarding the license and the data gathering process, we asked our own community for help, here you can read the Krita Artists thread about it: https://krita-artists.org/t/call-for-donation-of-artworks-for-the-fast-line-art-project/96401 .
The link to our full dataset can be found below in the Dataset section.
Model architectureAll main layers are either convolutional or deconvolutional (at the end of the model). After every (de)convolutional layer except for the last one there is a ReLu activation layer, and after the last convolution there is a sigmoid activation layer.
Python packages used: Pillow, Numpy, PyTorch and OpenvinoNumpy is a standard library for all kinds of arrays and advanced array operations and we used Pillow for reading images and converting them into numpy arrays and back. For training, we used PyTorch, while in the Krita plugin we used Openvino for inference (processing through the network).
Using NPU for inference
This table shows the result of benchmark_app, which is a tool that’s provided with Intel’s python package openvino. It tests the model in isolation on random data. As you can see, the NPU was several times faster than the CPU on the same machine.
On the other hand, introducing NPU added a challenge: the only models that can run on NPU are static models, meaning the input size is known at the time of saving the model to file. To solve this, the plugin first cuts the canvas into smaller parts of a specified size (which depends on the model file), and then proceeds to process all of them and finally stitch the results together. To avoid artifacts on the areas next to the stitching, all of the parts are cut with a little bit of a margin and the margin is later cut off.
How to train your own modelTo train your own model, you’ll need some technical skills, pairs of pictures (input and the expected output) and a powerful computer. You might also need quite a lot of space on your hard drive, though you can just remove unnecessary older models if you start having issues with lack of space.
Drivers & preparationYou’ll need to install Python3 and the following packages: Pillow, openvino, numpy, torch. For quantization of the model you will also need nncf and sklearn. If I missed anything, it will complain, so just install those packages it mentions too.
If you’re on Windows, you probably have drivers for NPU and dedicated GPU. On Linux, you might need to install NPU drivers before you’ll be able to use it: https://docs.openvino.ai/2024/get-started/configurations/configurations-intel-npu.html .
Moreover if you want to use iGPU for training (which might still be significantly faster than on CPU), you’ll probably need to use something like IPEX which allows PyTorch to use an “XPU” device, which is just your iGPU. It’s not tested or recommended since I personally haven’t been able to use it because my Python version was higher than the instruction expects, but the instruction is here: https://pytorch-extension.intel.com/installation?platform=gpu&version=v2.5.10%2Bxpu .
The sanity check for the installation is as follows:
python3 -c "import torch; import intel_extension_for_pytorch as ipex; print(f'Packages versions:'); print(f'Torch version: {torch.__version__}'); print(f'IPEX version: {ipex.__version__}'); print(f'Devices:'); print(f'Torch XPU device count: {torch.xpu.device_count()}'); [print(f'[Device {i}]: {torch.xpu.get_device_properties(i)}') for i in range(torch.xpu.device_count())];"
It should show more than 0 devices with some basic properties.
If you manage to get XPU device working on your machine, you’ll still need to edit the training scripts so they’ll able to use it: https://intel.github.io/intel-extension-for-pytorch/xpu/latest/tutorials/getting_started.html (most probably you’ll just need to add this line:
import intel_extension_for_pytorch as ipex
to the script on the very top, just underneath “import torch”, and use “xpu” as the device name when invoking the script, and it should work. But as I said, the scripts hasn’t been tested for that.
You’ll need some pictures to be able to train your model. The pictures must be in pairs, every pair must contain a sketch (input) and a lineart picture (expected output). The better quality of the dataset, the better the results.
Before training, it’s best if you augment the data: that means the pictures are rotated, scaled up or down, and mirrored. Currently the data augmentation script also performs an inversion with the assumption that training on inverted pictures would bring the results faster (considering that black means zero means no signal, and we’d like that to be the background, so the models learn the lines, not the background around lines).
How to use the data augmentation script is explained below in the detailed instruction for the training part.
Here’s the dataset that we used (please read the license carefully if you want to use it): https://files.kde.org/krita/extras/FastSketchCleanupPluginKritaDataset.zip
Choice of model and other parametersFor quick results, use tooSmallConv; if you have more time and resources, typicalDeep might be a better idea. If you have access to a powerful GPU machine, you might try original or originalSmaller, which represent the original description of the model from the SIGGRAPH article by Simo-Sierra 2016, and a smaller version of it.
Use adadelta as the optimizer.
You can use either blackWhite or mse as the loss function; mse is classic, but blackWhite might lead to faster results since it lowers the relative error on the fully white or fully black areas (based on the expected output picture).
Training-
Clone the repository at https://invent.kde.org/tymond/fast-line-art (at 33869b6)
git clone https://invent.kde.org/tymond/fast-line-art.git -
Then, prepare the folder:
- Create a new folder for the training.
- In the folder, run:
python3 [repository folder]/spawnExperiment.py --path [path to new folder, either relative or absolute] --note "[your personal note about the experiment]"
-
Prepare data:
- If you have existing augmented dataset, put it all in data/training/ and data/verify/, keeping in mind that paired pictures in ink/ and sketch/ subfolders must have the exact same names (for example if you have sketch.png and ink.png as data, you need to put one in sketch/ as picture.png and another in ink/ as picture.png to be paired).
- If you don't have existing augmented dataset:
- Put all your raw data in data/raw/, keeping in mind that paired pictures should have the exact same names with added prefix either ink_ or sketch_ (for example if you have picture_1.png being the sketch picture and picture_2.png being the ink picture, you need to name them sketch_picture.png and ink_picture.png respectively.)
- Run the data preparer script:
python3 [repository folder]/dataPreparer.py -t taskfile.yml
That will augment the data in the raw directory in order for the training to be more successful.
-
Edit the taskfile.yml file to your liking. The most important parts you want to change are:
- model type - code name for the model type, use tinyTinier, tooSmallConv, typicalDeep or tinyNarrowerShallow
- optimizer - type of optimizer, use adadelta or sgd
- learning rate - learning rate for sgd if in use
- loss function - code name for loss function, use mse for mean squared error or blackWhite for a custom loss function based on mse, but a bit smaller for pixels where the target image pixel value is close to 0.5
-
Run the training code:
python3 [repository folder]/train.py -t taskfile.yml -d "cpu"On Linux, if you want it to run in a background, add “&” at the end. If it runs in a foreground, you can pause the training just by pressing ctrl+C, and if it runs in a background, find a process id (using either “jobs -l” command or “ps aux | grep train.py” command, the first number would be the process id) and kill it using “kill [process id]” command. Your results will still be in the folder, and you’ll be able to resume the training using the same command.
-
Convert the model to an openvino model:
python3 [repository folder]/modelConverter.py -s [size of the input, recommended 256] -t [input model name, from pytorch] -o [openvino model name, must end with .xml] -
Place both the .xml and .bin model files in your Krita resource folder (inside pykrita/fast_sketch_cleanup subfolder) alongside other models to use them in the plugin.
Python Morsels: Merging dictionaries in Python
Merging dictionaries in Python is usually as simple as a single pipe character.
Table of contents
- Merging dictionaries with | in Python
- Merging dictionaries with the update method
- Merging dictionaries with **
- The difference between | and **
- Handling duplicate keys when merging
- The | operator performs a "union" between dictionaries
- Join dictionaries with the | operator
First let's talk about the simplest way to merge dictionaries, which will usually be all that you need.
Here are two dictionaries:
>>> context = {"language": "en", "timezone": "UTC"} >>> more_context = {"title": "Home", "breadcrumbs": ["Home"]}We'd like to make a new third dictionary that combines these two. This new dictionary should contain all the key-value pairs from both dictionaries.
The easiest way to do this is to use the pipe (|) operator:
>>> new_context = context | more_contextThis made a new dictionary that contains all the items from both of the two initial dictionaries:
>>> new_context {'language': 'en', 'timezone': 'UTC', 'title': 'Home', 'breadcrumbs': ['Home']}Using the | operator is basically the same as making a new empty dictionary, and then looping over all the items in the first dictionary and then all the items in the second dictionary, and adding all of them to the new dictionary:
>>> new_context = {} >>> for key, value in context.items(): ... new_context[key] = value ... >>> for key, value in more_context.items(): ... new_context[key] = value ... >>> new_context {'language': 'en', 'timezone': 'UTC', 'title': 'Home', 'breadcrumbs': ['Home']} Merging dictionaries with the update methodWhat if we wanted to …

Kdenlive 24.12.0 released
We are happy to announce Kdenlive 24.12. This release focuses on bug fixes, improved stability, and usability enhancements across the board. Numerous crashes and glitches have been addressed, including issues with audio capture, effect zones, high DPI display rendering, and subtitle editing. Proxies, rotoscoping, and project management workflows have been significantly refined, resolving lags, incorrect EXIF orientation handling, and archiving problems. We’ve managed to sneak in some little nifty features as well like the ability to resize multiple timeline items, Shift + Del shortcut to extract clips from the timeline, added actions to quickly add Marker/Guides in a specific category and mixes (same track transitions) can be 1 frame long.
Under the hood, we’ve dropped support for Qt5 and now require Qt6, alongside updated dependencies (MLT 7.28 and KF 6.3). This release comes with a lot of code cleanups and refactored Whisper settings. Optimized threading and memory management. Additionally, fail-safe measures have been taken to prevent invalid project profiles and script names.
Subtitles
We’ve added support for Advanced SubStation Alpha (ASS) subtitles, a widely used text-based format renowned for its flexibility in creating highly styled and customizable subtitles. ASS subtitles support advanced features such as font family, size, and color; text outlines and shadows; alignment and positioning; scaling and rotation; margins and spacing; and effects, including masking and other enhancements.
Subtitle Manager
The new subtitle manager is now integrated with style management and has been divided into four sections: Files, Layers and Content, Style, and Info, which correspond to the four main components of ASS subtitles.
Files – create, import and export subtitles
Layers and Content – create/remove subtitle tracks and apply styling
Styles – create and manage styles
Info – displays information about subtitles
Subtitle Style Editor
The new and powerful Subtitle Style Editor allows you to control all the styling capabilities of the ASS format. Animated Subtitles
The ASS format supports three types of effects: Banner, where the text scrolls sideways across the screen; Scroll, where the text moves vertically; and Karaoke, where each word is highlighted in sync with the audio. Currently, only the Banner and Scroll effects are accessible through the user interface, but additional styling, including Karaoke effects, can be applied using ASS tags. Currently, only the Banner and Scroll effects are accessible through the user interface, but additional styling, including Karaoke effects, can be applied using ASS tags. Speech-to-Text
We’ve polished the Speech to Text features ensuring a smoother and more reliable experience. Seamless installation, GPU translation and threading issues have fixed. We’ve also resolved issues with the display of Vosk, Whisper and Seamless model folder sizes on Windows. Added the ability to update all virtual environment packages have updated to the latest version of Whisper. Lastly, the Whisper settings interface has been refactored.
Effects
With this version, we complete the final task of our fundraiser: builtin effects and a redesigned effects interface. Rendering of keyframe types like Bounce, Circular, and Exponential has been improved, alongside fixes for zone-based effects, rotoscoping lag, shape filter rendering, improved precision for time remapping, motion tracker models and prev/next seeking in monitor. It is also now possible to have single-frame mixes (same track transitions).
Interface redesign
The new Effect Stack redesign enhances usability with clearer organization of keyframeable and non-keyframeable parameters, improved layout consistency, more compact and clean. We’ve also added info buttons in effect headers for quick access to documentation. Built-in Effects
To make your workflow much more fluid, the new effects panel gives direct access to effect parameters, allowing to quickly and easily adjust them. Currently built-in effects are Transform and Flip for video clips and Volume for audio clips. Built-in effects can be enabled/disabled in the settings.
New EffectsAs usual there is always room for some eye candy, so we’ve added two color correction effects, HSL Primaries and HSL Range as well as GPS Effects (Images below displaying Distance, Altitude and Speed among many other values).

The Python Show: 50 - Imposter Syndrome
Imposter syndrome is a topic that some engineers and developers struggle with. It’s basically a type of self-doubt. WebMD has a good description and some good ideas for fighting self-doubt.
Ways to combat imposter syndrome:
List out your accomplishments on a regular basis (keep it in a Google doc)
Review the list
If you receive compliments, record them (make a copy, write it down, take a screenshot) and store those too
Reminder: you will never stop learning. Embrace it!
🚨 Python devs, this one’s for you. If you’re tired of struggling with context-unaware coding tools, let me introduce you to a game-changer I’ve been exploring: Zencoder.
Here’s why it’s caught my attention:
1️⃣ Python-friendly to its core. Whether you’re building web apps, analyzing data, or automating tasks, Zencoder delivers context-aware suggestions that actually understand your project. No more “guessing” code completions. But don't worry it supports other programming languages as well!
2️⃣ Custom AI agents you can create and tweak. Imagine having a bot that automates your repetitive Python tasks—refactoring, testing, debugging—leaving you free to tackle the fun parts.
3️⃣ Natural language to code magic. Want to build a quick game for fun or a Python script in seconds? Just describe it in plain English, and Zencoder makes it happen. (Yes, it’s that good.)
I’ve also been loving how it seamlessly supports unit testing and bug fixing—a massive time-saver for clean code lovers like me.
Check out Zencoder if you’re looking for an AI assistant that actually gets Python devs:

How does this system differ from previous versions, and how can you take advantage of its capabilities when building your website? Find out why you should consider choosing this system or upgrading to Drupal 11.
Freelock Blog: Add conflict detection on reservation forms
Our Yacht Club client has three workslips that members can reserve for up to 3 days. Using core taxonomy, content types, views, and the Events, Conditions, and Actions (ECA) module, we built a system to allow members to make reservations, and have the system prevent double-bookings.
2024 end-of-year review: policy and standards
As 2024 draws to a close, the Open Source Initiative (OSI) reflects on an eventful year marked by significant achievements in advocating for Open Source principles in policy and standards development worldwide. Below, we highlight key milestones, initiatives and ongoing work from the year.
Global engagementsColumbia Convening on AI: Led by the Mozilla Foundation and the Columbia Institute of Global Politics, OSI participated in this collaboration to build a framework for openness in AI. The convening produced technical and policy memorandums advancing the discourse on open and equitable AI development.
United Nations “OSPOs for Good”: OSI participated in a panel on this NYC event, emphasizing Open Source’s role in defining Open Source AI. Collaborative discussions underscored the growing recognition of Open Source in global governance.
Open Source Congress: OSI participated in the second Open Source Congress, hosted in Beijing by the Open Atom Foundation. This event fostered collaboration among nonprofit leaders in the Open Source ecosystem.
Digital Public Goods Alliance (DPGA): OSI continued its active role as a member of the DPGA, contributing to the Annual Members Meeting held in Singapore. The event highlighted OSI’s involvement in promoting open standards, software and AI models as part of the global ecosystem of Digital Public Goods.
European policy workCyber Resilience Act (CRA): After having successfully helped the community to understand the challenges of the first draft of the Cyber Resilience act, OSI’s focus shifted to implementation in the second half of the year, joining the Eclipse Open Regulatory Compliance Group, a group designed to help Open Source developers implement the CRA. In addition to this, we are preparing to work with European standardization organizations to ensure the standards developed for the CRA are implementable for Open Source developers.
Standardization Advocacy: OSI provided feedback on the Standard Essential Patents Regulation and standardization frameworks, ensuring they align with Open Source principles. Efforts included ensuring software standards can be freely implemented by the community. In parallel to this, OSI is working to find ways to involve Open Source developers in the standardization process. OSI remains a member at ETSI and regularly engages with representatives of other standards bodies.
Collaboration with Eclipse Foundation: A Memorandum of Understanding with the Eclipse Foundation marked a strategic partnership to influence Open Source AI policy and the implementation of the Cyber Resilience Act.
AI Act Advocacy: After the introduction of an exemption for Open Source AI in the AI act, lawmakers have faced an unprecedented wave of openwashing in the AI space. OSI has expanded its educational efforts, meeting with lawmakers and staffers, presenting the Open Source AI Definition, and highlighting cases of openwashing. In addition to this, OSI was selected as one of the stakeholders for the drafting of the Code of Practice on General-Purpose AI, a set of rules designed to help companies comply with the AI act. OSI has used this opportunity to help address some of the challenges Open Source AI developers face, and to clearly differentiate between Open Source and open weight AI.
New Appointments: OSI welcomed Jordan Maris as EU Policy Analyst, strengthening its advocacy presence in Brussels.
Community Outreach: Blogs, workshops and participation in conferences like FOSDEM and CPDP-ai in Brussels ensured robust engagement with diverse stakeholders.
U.S. policy workOpen Policy Alliance: Designed to bring nonprofit organizations together, the OPA focuses on educating and informing U.S. public policy decisions related to Open Source software, content, research and education. OSI’s leadership in the OPA strengthened policy efforts across the U.S., including invited participation roundtables with federal agencies, responding to public calls for comments on security, sustainability and open source AI models, educating policymakers on Open Source’s societal benefits, and securing philanthropic support for Open Source policy initiatives.
AI Policy Development: Partnering with Carnegie Mellon University, OSI co-founded the Open Forum for AI, focusing on human-centered AI development. The initiative reflects OSI’s commitment to ensuring AI policies protect openness and transparency.
Federal Advocacy: OSI contributed responses to Requests for Comments (RFCs) on AI and cybersecurity, emphasizing the value of openness in safeguarding public interest, working together with other organizations like the Mozilla Foundation and the Center for Democracy & Technology.
Community Outreach: Blogs, workshops and participation in events like All Things Open in Raleigh, NC and Open Forum for AI in Washington D.C. fostered strong engagement with a diverse range of stakeholders.
Looking ahead: 2025The year ahead promises continued focus on:
- Implementing AI Act and CRA provisions
- Expanding outreach and educational programs for policymakers
- Strengthening global partnerships
OSI remains committed to championing Open Source principles in the policy landscape, ensuring developers and communities worldwide thrive in an environment of transparency, collaboration and innovation.
We extend our gratitude to our partners, allies and community members for their support in advancing OSI’s mission. Together, we are shaping a more open and equitable future. Please consider donating to or sponsoring the OSI.
