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 .

Scrapy is a robust Python web scraping framework that can manage requests asynchronously, follow links, and parse site content. To store scraped data, you can use MongoDB, a scalable NoSQL database, that stores data in a JSON-like format. Combining Scrapy with MongoDB offers a powerful solution for web scraping projects, leveraging Scrapy’s efficiency and MongoDB’s flexible data storage.

In this tutorial, you’ll learn how to:

• Set up and configure a Scrapy project
• Build a functional web scraper with Scrapy
• Extract data from websites using selectors
• Store scraped data in a MongoDB database
• Test and debug your Scrapy web scraper

If you’re new to web scraping and you’re looking for flexible and scalable tooling, then this is the right tutorial for you. You’ll also benefit from learning this tool kit if you’ve scraped sites before, but the complexity of your project has outgrown using Beautiful Soup and Requests.

To get the most out of this tutorial, you should have basic Python programming knowledge, understand object-oriented programming, comfortably work with third-party packages, and be familiar with HTML and CSS.

By the end, you’ll know how to get, parse, and store static data from the Internet, and you’ll be familiar with several useful tools that allow you to go much deeper.

Interactive Quiz

Web Scraping With Scrapy and MongoDB

In this quiz, you'll test your understanding of web scraping with Scrapy and MongoDB. You'll revisit how to set up a Scrapy project, build a functional web scraper, extract data from websites, store scraped data in MongoDB, and test and debug your Scrapy web scraper.

Prepare the Scraper Scaffolding

You’ll start by setting up the necessary tools and creating a basic project structure that will serve as the backbone for your scraping tasks.

While working through the tutorial, you’ll build a complete web scraping project, approaching it as an ETL (Extract, Transform, Load) process:

• Extract data from the website using a Scrapy spider as your web crawler.
• Transform this data, for example by cleaning or validating it, using an item pipeline.
• Load the transformed data into a storage system like MongoDB with an item pipeline.

Scrapy provides scaffolding for all of these processes, and you’ll tap into that scaffolding to learn web scraping following the robust structure that Scrapy provides and that numerous enterprise-scale web scraping projects rely on.

Note: In a Scrapy web scraping project, a spider is a Python class that defines how to crawl a specific website or a group of websites. It contains the logic for making requests, parsing responses, and extracting the desired data.

First, you’ll install Scrapy and create a new Scrapy project, then explore the auto-generated project structure to ensure that you’re well-equipped to proceed with building a performant web scraper.

Install the Scrapy Package

To get started with Scrapy, you first need to install it using pip. Create and activate a virtual environment to keep the installation separate from your global Python installation. Then, you can install Scrapy:

Shell (venv) $ python -m pip install scrapy Copied!

After the installation is complete, you can verify it by running the scrapy command and viewing the output:

Shell (venv) $ scrapy Scrapy 2.11.2 - no active project Usage: scrapy <command> [options] [args] Available commands: bench Run quick benchmark test fetch Fetch a URL using the Scrapy downloader genspider Generate new spider using pre-defined templates runspider Run a self-contained spider (without creating a project) settings Get settings values shell Interactive scraping console startproject Create new project version Print Scrapy version view Open URL in browser, as seen by Scrapy [ more ] More commands available when run from project directory Use "scrapy <command> -h" to see more info about a command Copied!

The command-line (CLI) program should display the help text of Scrapy. This confirms that you installed the package correctly. You’ll next run the highlighted startproject command to create a project.

Create a Scrapy Project

Scrapy is built around projects. Generally, you’ll create a new project for each web scraping project that you’re working on. In this tutorial, you’ll work on scraping a website called Books to Scrape, so you can call your project books.

As you may have already identified in the help text, the framework provides a command to create a new project:

Shell (venv) $ scrapy startproject books Copied! Read the full article at https://realpython.com/web-scraping-with-scrapy-and-mongodb/ »

The Open Source Initiative (OSI) is running a blog series to introduce some of the people who have been actively involved in the Open Source AI Definition (OSAID) co-design process. The co-design methodology allows for the integration of diverging perspectives into one just, cohesive and feasible standard. Support and contribution from a significant and broad group of stakeholders is imperative to the Open Source process and is proven to bring diverse issues to light, deliver swift outputs and garner community buy-in.

This series features the voices of the volunteers who have helped shape and are shaping the Definition.

Meet Ezequiel Lanza

What’s your background related to Open Source and AI?

I’ve been working in AI for more than 10 years (Yes, before ChatGPT!). With a background in engineering, I’ve consistently focused on building and supporting AI applications, particularly in machine learning and data science. Over the years, I’ve contributed to and collaborated on various projects. A few years ago, I decided to pursue a master’s in data science to deepen my theoretical knowledge and further enhance my skills. Open Source has also been a significant part of my work; the frameworks, tools and community have continually drawn me in, making me an active participant in this evolving conversation for years.

What motivated you to join this co-design process to define Open Source AI?

AI owes much of its progress to Open Source, and it’s essential for continued innovation. My experience in both AI and Open Source spans many years, and I believe this co-design process offers a unique chance to contribute meaningfully. It’s not just about sharing my insights but also about learning from other professionals across AI and different disciplines. This collective knowledge and diverse perspectives make this initiative truly powerful and enriching, to shape the future of Open Source AI together.

Can you describe your experience participating in this process? What did you most enjoy about it, and what were some of the challenges you faced?

Participating in this process has been both rewarding and challenging. I’ve particularly enjoyed engaging with diverse groups and hearing different perspectives. The in-person events, such as All Things Open in Raleigh in 2023, have been valuable for fostering direct collaboration and building relationships. However, balancing these meetings with my work duties has been challenging. Coordinating schedules and managing time effectively to attend all the relevant discussions can be demanding. Despite these challenges, the insights and progress have made the effort worthwhile.

Why do you think AI should be Open Source?

We often say AI is everywhere, and while that’s partially true, I believe AI will be everywhere, significantly impacting our lives. However, AI’s full potential can only be realized if it is open and accessible to everyone. Open Source AI should also foster innovation by enabling developers and researchers from all backgrounds to contribute to and improve existing models, frameworks and tools, allowing freedom of expression. Without open access, involvement in AI can be costly, limiting participation to only a few large companies. Open Source AI should aim to democratize access, allowing small businesses, startups and individuals to leverage powerful tools that might otherwise be out of reach due to cost or proprietary barriers.

What do you think is the role of data in Open Source AI?

Data is essential for any AI system. Initially, from my ML bias perspective, open and accessible datasets were crucial for effective ML development. However, I’ve reevaluated this perspective, considering how to adapt the system while staying true to Open Source principles. As AI models, particularly GenAI like LLMs, become increasingly complex, I’ve come to value the models themselves. For example, Generative AI requires vast amounts of data, and gaining access to this data can be a significant challenge.

This insight has led me to consider what I—whether as a researcher, developer or user—truly need from a model to use/investigate it effectively. While understanding the data used in training is important, having access to specific datasets may not always be necessary. In approaches like federated learning, the model itself can be highly valuable while keeping data private, though understanding the nature of the data remains important. For LLMs, techniques such as fine-tuning, RAG and RAFT emphasize the benefits of accessing the model rather than the original dataset, providing substantial advantages to the community.

Sharing model architecture and weights is crucial, and data security can be maintained through methods like model introspection and fine-tuning, reducing the need for extensive dataset sharing.

Data is undoubtedly a critical component. However, the essence of Open Source AI lies in ensuring transparency, then the focus should be on how data is used in training models. Documenting which datasets were used and the data handling processes is essential. This transparency helps the community understand the origins of the data, assess potential biases and ensure the responsible use of data in model development. While sharing the exact datasets may not always be necessary, providing clear information about data sources and usage practices is crucial for maintaining trust and integrity in Open Source AI.

Has your personal definition of Open Source AI changed along the way? What new perspectives or ideas did you encounter while participating in the co-design process?

Of course, it changed and evolved – that’s what a thought process is about. I’d be stubborn if I never changed my perspective along the way. I’ve often questioned even the most fundamental concepts I’ve relied on for years, avoiding easy or lazy assumptions. This thorough process has been essential in refining my understanding of Open Source AI. Engaging in meaningful exchanges with others has shown me the importance of practical definitions that can be implemented in real-world scenarios. While striving for an ideal, flawless definition is tempting, I’ve found that embracing a pragmatic approach is ultimately more beneficial.

What do you think the primary benefit will be once there is a clear definition of Open Source AI?

As I see it, the Open Source AI Definition will support the growth, and it will be the first big step. The primary benefit of having a clear definition of Open Source AI will be increased clarity and consistency in the field. This will enhance collaboration by setting clear standards and expectations for researchers, developers and organizations. It will also improve transparency by ensuring that AI models and tools genuinely follow Open Source principles, fostering trust in their development and sharing.

A clear definition will create standardized practices and guidelines, making it easier to evaluate and compare different Open Source AI projects.

What do you think are the next steps for the community involved in Open Source AI?

The next steps for the community should start with setting up a certification process for AI models to ensure they meet certain standards. This could include tools to help automate the process. After that, it would be helpful to offer templates and best practice guides for AI models. This will support model designers in creating high-quality, compliant systems and make the development process smoother and more consistent.

We are looking for the next group of organizers to own and lead the 2026 DjangoCon Europe conference. Could your town - or your football stadium, circus tent, private island or city hall - host this wonderful community event?

DjangoCon Europe is a major pillar of the Django community, as people from across the world meet and share. This includes many qualities that make it a unique event - unconventional and conventional venues, creative happenings, a feast of talks and a dedication to inclusion and diversity.

Hosting a DjangoCon is an ambitious undertaking. It's hard work, but each year it has been successfully run by a team of community volunteers, not all of whom have had previous experience - more important is enthusiasm, organizational skills, the ability to plan and manage budgets, time and people - and plenty of time to invest in the project.

For 2026, we want to kickstart the organization much earlier than in previous years to allow more flexibility for the organizing team, and open up more opportunities for support from our DjangoCon Europe support working group.

Step 1: Submit your expression of interest

If you’re considering organizing DjangoCon Europe (🙌 great!), fill in our DjangoCon Europe 2026 expression of interest form with your contact details. No need to fill in all the information at this stage if you don’t have it all already, we’ll reach out and help you figure it out.

Express your interest in organizing

Step 2: We’re here to help!

We've set up a DjangoCon Europe support working group of previous organizers that you can reach out to with questions about organizing and running a DjangoCon Europe.

The group will be in touch with everyone submitting the expression of interest form, or you can reach out to them directly: european-organizers-support@djangoproject.com

We'd love to hear from you as soon as possible, so your proposal can be finalized and sent to the DSF board by October 6th 2024. The selected hosts will be publicly announced at DjangoCon Europe 2025 by the current organizers.

Step 3: Submitting the proposal

The more detailed and complete your final proposal is, the better. Basic details include:

• Organizing committee members: You won’t have a full team yet, probably, naming just some core team members is enough.
• The legal entity that is intended to run the conference: Even if the entity does not exist yet, please share how you are planning to set it up.
• Dates: See “What dates are possible in 2026?” below. We must avoid conflicts with major holidays, EuroPython, DjangoCon US, and PyCon US.
• Venue(s), including size, number of possible attendees, pictures, accessibility concerns, catering, etc.
• Transport links and accommodation: Can your venue be reached by international travelers?
• Budgets and ticket prices: Talk to the DjangoCon Europe Support group to get help with this, including information on past event budgets.

We also like to see:

• Timelines
• Pictures
• Plans for online participation, and other ways to make the event more inclusive and reduce its environmental footprint
• Draft agreements with providers
• Alternatives you have considered

Have a look at our proposed DjangoCon Europe 2026 Licensing Agreement for the fine print on contractual requirements and involvement of the Django Software Foundation.

Submit your completed proposal by October 6th 2024 via our DjangoCon Europe 2026 expression of interest form, this time filling in as many fields as possible. We look forward to reviewing great proposals that continue the excellence the whole community associates with DjangoCon Europe.

Q&A Can I organize a conference alone?

We strongly recommend that a team of people submit an application.

I/we don’t have a legal entity yet, is that a problem?

Depending on your jurisdiction, this is usually not a problem. But please share your plans about the entity you will use or form in your application.

Do I/we need experience with organizing conferences?

The support group is here to help you succeed. From experience, we know that many core groups of 2-3 people have been able to run a DjangoCon with guidance from previous organizers and help from volunteers.

What is required in order to announce an event?

Ultimately, a contract with the venue confirming the dates is crucial, since announcing a conference makes people book calendars, holidays, buy transportation and accommodation etc. This, however, would only be relevant after the DSF board has concluded the application process. Naturally, the application itself cannot contain any guarantees, but it’s good to check concrete dates with your venues to ensure they are actually open and currently available, before suggesting these dates in the application.

Do we have to do everything ourselves?

No. You will definitely be offered lots of help by the community. Typically, conference organizers will divide responsibilities into different teams, making it possible for more volunteers to join. Local organizers are free to choose which areas they want to invite the community to help out with, and a call will go out through a blog post announcement on djangoproject.com and social media.

What kind of support can we expect from the Django Software Foundation?

The DSF regularly provides grant funding to DjangoCon organizers, to the extent of $6,000 in recent editions. We also offer support via specific working groups:

• The dedicated DjangoCon Europe support working group.
• The social media working group can help you promote the event.
• The Code of Conduct working group works with all event organizers.

In addition, a lot of Individual Members of the DSF regularly volunteer at community events. If your team aren’t Individual Members, we can reach out to them on your behalf to find volunteers.

What dates are possible in 2026?

For 2026, DjangoCon Europe should happen between January 5th and April 27th, or June 4th and June 28th. This is to avoid the following community events’ provisional dates:

• PyCon US 2026: May 2026
• EuroPython 2026: July 2026
• DjangoCon US 2026: September - October 2026
• DjangoCon Africa 2026: August - September 2026

We also want to avoid the following holidays:

• New Year's Day: Wednesday 1st January 2026
• Chinese New Year: Tuesday 17th February 2026
• Eid Al-Fitr: Friday 20th March 2026
• Passover: Wednesday 1st - Thursday 9th April 2026
• Easter: Sunday 5th April 2026
• Eid Al-Adha: Tuesday 26th - Friday 29th May 2026
• Rosh Hashanah: Friday 11th - Sunday 13th September 2026
• Yom Kippur: Sunday 20th - Monday 21st September 2026

What cities or countries are possible?

Any city in Europe. This can be a city or country where DjangoCon Europe has happened in the past (Vigo, Edinburgh, Porto, Copenhagen, Heidelberg, Florence, Budapest, Cardiff, Toulon, Warsaw, Zurich, Amsterdam, Berlin), or a new locale.

PyPy v7.3.17: release of python 2.7 and 3.10

The PyPy team is proud to release version 7.3.17 of PyPy.

This release includes a new RISC-V JIT backend, an improved REPL based on work by the CPython team, and better JIT optimizations of integer operations. Special shout-outs to Logan Chien for the RISC-V backend work, to Nico Rittinghaus for better integer optimization in the JIT, and the CPython team that has worked on the repl.

The release includes two different interpreters:

• PyPy2.7, which is an interpreter supporting the syntax and the features of Python 2.7 including the stdlib for CPython 2.7.18+ (the + is for backported security updates)

• PyPy3.10, which is an interpreter supporting the syntax and the features of Python 3.10, including the stdlib for CPython 3.10.14.

The interpreters are based on much the same codebase, thus the dual release. This is a micro release, all APIs are compatible with the other 7.3 releases. It follows after 7.3.16 release on April 23, 2024.

We recommend updating. You can find links to download the releases here:

https://pypy.org/download.html

We would like to thank our donors for the continued support of the PyPy project. If PyPy is not quite good enough for your needs, we are available for direct consulting work. If PyPy is helping you out, we would love to hear about it and encourage submissions to our blog via a pull request to https://github.com/pypy/pypy.org

We would also like to thank our contributors and encourage new people to join the project. PyPy has many layers and we need help with all of them: bug fixes, PyPy and RPython documentation improvements, or general help with making RPython's JIT even better.

If you are a python library maintainer and use C-extensions, please consider making a HPy / CFFI / cppyy version of your library that would be performant on PyPy. In any case, both cibuildwheel and the multibuild system support building wheels for PyPy.

RISC-V backend for the JIT

PyPy's JIT has added support for generating 64-bit RISC-V machine code at runtime (RV64-IMAD, specifically). So far we are not releasing binaries for any RISC-V platforms, but there are instructions on how to cross-compile binaries.

REPL Improvements

The biggest user-visible change of the release is new features in the repl of PyPy3.10. CPython 3.13 has adopted and extended PyPy's pure-Python repl, adding a number of features and fixing a number or bugs in the process. We have backported and added the following features:

• Prompts and tracebacks use terminal colors, as well as terminal hyperlinks for file names.

• Bracketed paste enable pasting several lines of input into the terminal without auto-indentation getting in the way.

• A special interactive help browser (F1), history browser (F2), explicit paste mode (F3).

• Support for Ctrl-<left/right> to jump over whole words at a time.

See the CPython documentation for further details. Thanks to Łukasz Langa, Pablo Galindo Salgado and the other CPython devs involved in this work.

Better JIT optimizations of integer operations

The optimizers of PyPy's JIT have become much better at reasoning about and optimizing integer operations. This is done with a new "knownbits" abstract domain. In many programs that do bit-manipulation of integers, some of the bits of the integer variables of the program can be statically known. Here's a simple example:

x = a | 1 ... if x & 1: ... else: ...

With the new abstract domain, the JIT can optimize the if-condition to True, because it already knows that the lowest bit of x must be set. This optimization applies to all Python-integers that fit into a machine word (PyPy optimistically picks between two different representations for int, depending on the size of the value). Unfortunately there is very little impact of this change on almost all Python code, because intensive bit-manipulation is rare in Python. However, the change leads to significant performance improvements in Pydrofoil (the RPython-based RISC-V/ARM emulators that are automatically generated from high-level Sail specifications of the respective ISAs, and that use the RPython JIT to improve performance).

PyPy versions and speed.pypy.org

The keen-eyed will have noticed no mention of Python version 3.9 in the releases above. Typically we will maintain only one version of Python3, but due to PyPy3.9 support on conda-forge we maintained multiple versions from the first release of PyPy3.10 in PyPy v7.3.12 (Dec 2022). Conda-forge is sunsetting its PyPy support, which means we can drop PyPy3.9. Since that was the major driver of benchmarks at https://speed.pypy.org, we revamped the site to showcase PyPy3.9, PyPy3.10, and various versions of cpython on the home page. For historical reasons, the "baseline" for comparison is still cpython 3.7.19.

We will keep the buildbots building PyPY3.9 until the end of August, these builds will still be available on the nightly builds tab of the buildbot.

What is PyPy?

PyPy is a Python interpreter, a drop-in replacement for CPython It's fast (PyPy and CPython performance comparison) due to its integrated tracing JIT compiler.

We also welcome developers of other dynamic languages to see what RPython can do for them.

We provide binary builds for:

• x86 machines on most common operating systems (Linux 32/64 bits, Mac OS 64 bits, Windows 64 bits)

• 64-bit ARM machines running Linux (aarch64) and macos (macos_arm64).

PyPy supports Windows 32-bit, Linux PPC64 big- and little-endian, Linux ARM 32 bit, RISC-V RV64IMAFD Linux, and s390x Linux but does not release binaries. Please reach out to us if you wish to sponsor binary releases for those platforms. Downstream packagers provide binary builds for debian, Fedora, conda, OpenBSD, FreeBSD, Gentoo, and more.

What else is new?

For more information about the 7.3.17 release, see the full changelog.

Please update, and continue to help us make pypy better.

Cheers, The PyPy Team

Setting up a multilingual website in Drupal opens the door to a global online marketplace, allowing businesses to reach different cultural audiences by presenting content in multiple languages. In this article, we will discuss the process of configuring a multilingual site on Drupal.

Greetings, Pythonistas- thank you so much for supporting the work of the Python Software Foundation (PSF) and the Python community! The current PSF Board has decided to invest more in connecting and serving the global Python community by establishing a forum to have regular conversations. The board members of the PSF with the support of PSF staff are excited to introduce monthly PSF Board Office Hours on the PSF Discord. The Office Hours will be sessions where you can share with us how we can help your community, express your perspectives, and provide feedback for the PSF.

What are the PSF Board Office Hours?

Similar to the PSF Grants Program Office Hours where PSF staff members help to answer questions regarding the PSF Grants Program, during the PSF Board Office Hours you can participate in a text-based live chat with PSF Board Directors. This is a chance to connect, share, and collaborate with the PSF Board and staff to improve our community together. Occasionally, we will have dedicated topics such as PyCon US and the PSF Board Elections for the office hour sessions.

Here is some of the work that we collaborate with staff and volunteers on:

• Promotion and outreach for the Python programming language
• Supporting local Python communities
• Organizing PyCon US
• Diversity and Inclusion in our community
• Support handling of Code of Conduct within our communities
• Support regional Python communities via the PSF Grants Program
• Furthering the mission of the PSF

Unless we have a dedicated topic for a session, you are not limited to talking with us about the above topics, although the discussions should be focused on Python, the PSF, and our community. If you think there’s something we can help with or we should know, we welcome you to come and talk to us!

The office hour sessions will take place on the PSF Discord server in the #psf-board channel.

Who will be at the office hours?

Some of the board members of the PSF will be attending each office hour, as well as members of the PSF Staff. The list of the PSF Board Directors can be found on our website. We are passionate Python community members who are happy to listen, help, and provide support to you. We are happy to follow up with you if there are any issues we cannot address immediately during the office hour sessions.
