Russell Coker: Source Code With Emoji

Planet Debian - 18 hours 20 min ago

The XKCD comic Code Quality [1] inspired me to test out emoji in source. I really should have done this years ago when that XKCD was first published.

The following code compiles in gcc and runs in the way that anyone who wants to write such code would want it to run. The hover text in the XKCD comic is correct. You could have a style guide for such programming, store error messages in the doctor and nurse emoji for example.

#include <stdio.h> int main() {   int 😇 = 1, 😈 = 2;   printf("😇=%d, 😈=%d\n", 😇, 😈);   return 0; }

To get this to display correctly in Debian you need to install the fonts-noto-color-emoji package (used by the KDE emoji picker that runs when you press Windows-. among other things) and restart programs that use emoji. The Konsole terminal emulator will probably need it’s profile settings changed to work with this if you ran Konsole before installing fonts-noto-color-emoji. The Kitty terminal emulator works if you restart it after installing fonts-noto-color-emoji.

This web page gives a list of HTML codes for emoji [2]. If I start writing real code with emoji variable names then I’ll have to update my source to HTML conversion script (which handles <>" and repeated spaces) to convert emoji.

I spent a couple of hours on this and I think it’s worth it. I have filed several Debian bug reports about improvements needed to issues related to emoji.

Russell Coker: Ubuntu 24.04 and Bubblewrap

Planet Debian - 18 hours 36 min ago

When using Bubblewrap (the bwrap command) to create a container in Ubuntu 24.04 you can expect to get one of the following error messages:

bwrap: loopback: Failed RTM_NEWADDR: Operation not permitted bwrap: setting up uid map: Permission denied

This is due to Ubuntu developers deciding to use Apparmor to restrict the creation of user namespaces. Here is a Ubuntu blog post about it [1].

To resolve that you could upgrade to SE Linux, but the other option is to create a file named /etc/apparmor.d/bwrap with the following contents:

abi <abi/4.0>, include <tunables/global> profile bwrap /usr/bin/bwrap flags=(unconfined) { userns, # Site-specific additions and overrides. See local/README for details. include if exists <local/bwrap> }

Then run “systemctl reload apparmor“.

Open Source AI Definition on the road: Looking back and forward

Open Source Initiative - Tue, 2024-04-23 13:15

With version 0.0.7 of the Open Source AI Definition just published, we are getting very close to a release candidate version in June, as planned. We’ve covered a lot of ground since FOSDEM 2024, where we presented draft 0.0.4. This month we presented at Open Source Summit North America (OSS NA 24) and ran a co-design workshop at the Legal and Licensing Workshop (LLW) in Gothenburg. We’re very close to a “feature complete”: below are the next steps and ideas on how you might get involved.

Opportunities to meet in person

We are taking the draft definition on the road and coming to a town near you! Or, kind of, that is if you live in any of the following cities or happen to be there on the given dates:

  1. North America 
    1. USA, Pittsburgh, PyCon US (May 17)
    2. USA, NYC OSPOs for Good (July 9-11)
    3. USA, Raleigh, All Things Open (October 27-29)
  2. Europe
    1. France, Paris, OW2 (June)
    2. France, Paris, data governance event (September)
  3. Africa
    1. Nigeria, Lagos, Sustain Africa (June)
  4. Latin America
    1. Argentina, Buenos Aires, Nerdearla (September 24-28)
  5. Asia Pacific
    1. Hong Kong, AI_Dev (August 23)

It’s important for you to catch up.

Draft v.0.0.5 at FOSDEM 2024

The talk “Moving a Step Closer to Defining Open Source AI” (click here to watch the recorded live stream) by Stefano Maffulli presented draft v.0.0.5, released a few days before. The process at the time was focusing on finding the required components to “use, study, share and modify” an AI system. 

Maffulli quickly summarized why OSI started the Deep Dive: AI process, after Copilot not only demonstrated machines’ ability to write functioning code but also highlighted the new role of data as input to the machine learning system. Recognizing there is no simple answer to the question “what is the source code of Copilot?” Maffulli focused OSI’s attention to finding the Open Source principles applied to AI together with stakeholders from academia, legal communities, tech companies, and civil rights groups.

Building the framework

OSI defined a process to co-design the Open Source AI Definition in public. This framework encompasses a clear definition of AI systems, a preamble outlining the rationale behind open source AI, a concise articulation of the freedoms users should enjoy, and a checklist for evaluating AI components and associated legal documents.

He highlighted the rapid progress and policy decisions that shaped the trajectory of software development, emphasizing the need to compress decades of evolution into a few months in the realm of AI. Stefano emphasized the importance of community feedback and collaboration in refining the definition of Open Source AI. With monthly draft releases, bi-weekly town halls, and an active forum, we gather diverse perspectives and insights to craft a robust definition.

OSS North America 2024 and next steps

Since FOSDEM, the Definition has reached version 0.0.7. First, working groups analyzed Pythia, OpenCV, Llama2 and Bloom  to find the preferred form of making modifications to the AI system, the fundamental unit for users to exercise their freedoms. Later, the groups shifted focus to reviewing the legal frameworks used by the components used by Pythia, OpenCV, Llama2 and Bloom. Together with the definition of AI system provided by the OECD, the preamble, out-of-scope issues and four freedoms, this draft looks very close to a full document. A new version is expected to be released very soon now. On the 16th of April, Ofer Hermoni of the Linux Foundation and Mer Joyce (OSI/DoBigGood) presented the work at the OSS NA 24 meeting in Seattle. A huge part of our job currently is getting this definition reviewed by as many stakeholders as possible. A far-reaching and diverse perspective is necessary as we aim for a global impact. 
To participate in shaping the definition of Open Source AI and stay updated on the latest developments, visit opensource.org/deepdive and engage with the ongoing discussions, participate and watch previous town hall meetings and draft releases.

Dries Buytaert: Evolving Drupal's Layout Builder to an Experience Builder

Planet Drupal - Tue, 2024-04-23 13:04

Imagine a world where installing Drupal instantly launches you into a creative experience, allowing you to build and style pages right out of the box, without any need for additional modules or configuration.

The introduction of Drupal's Layout Builder in 2018 was an important milestone toward this vision, but it was just the first step. Layout Builder provides site builders with a powerful drag-and-drop interface for creating and arranging content within customizable layouts.

Despite its success, there is a clear and pressing need to improve the existing Layout Builder. The numerous community-developed modules enhancing Layout Builder highlight the need for a more comprehensive solution.

That is why at DrupalCon Lille last year, I was excited to announce the "Next Generation Page Builder" initiative, aimed at improving and expanding the Layout Builder to provide a truly intuitive, out-of-the-box page-building experience.

Since announcing the 'Next Generation Page Builder', led by Lauri Eskola (Acquia), a Drupal Core Committer, we've done extensive research and planning.

Inspired by user feedback, we decided to make two changes. First, we decided to broaden our focus: not only will we improve the page-building features of Layout Builder, we will also integrate basic theming capabilities, enabling users to style their pages effortlessly without having to edit Twig files. Second, reflecting on this wider scope, we renamed the initiative from 'Next Generation Page Builder' to 'Experience Builder'.

In recent months, we explored several options for how to create such an Experience Builder, including accelerating development of the Layout Builder, switching to Gutenberg, adopting Paragraphs, or using the newly open-sourced Plasmic.

After thorough analysis and discussions with key stakeholders, including Automattic's Gutenberg team, the Drupal Core Committers decided the best approach is to expand the Layout Builder while also incorporating the best elements of Paragraphs.

Looking to the future, I hope the Experience Builder becomes the preferred Drupal tool for layout design, page building, and basic theming. Our main goal is to create a tool that site builders love, with an amazing out-of-the-box experience. By integrating key features from Paragraphs, we also aim to create a unified solution that reduces fragmentation, accelerates innovation, and ensures Drupal remains at the forefront of site building.

Our future success hinges on expanding Drupal's usability to a wider audience. Our CMS capabilities are often better than our competitors', but aren't always as user friendly. In the Drupal 7 era, Drupal was the OG (Original Great) of low-code but today we are being outpaced by competitors in terms of ease of use. Without user experience improvements, we'll lose ground. The Experience Builder initiative is all about introducing more people to the power of Drupal.

I feel strongly that a unified Experience Builder is one of the most important initiatives we can undertake right now.

Developing an Experience Builder is a big task that will require substantial effort, extensive collaboration, and significant expertise in user experience and design. As Drupal Core Committers, we are driven by a sense of urgency to advance this initiative. We are committed to moving quickly and iterating rapidly, but to succeed, we also need your support. There will be many opportunities for the community to collaborate and contribute to this initiative.

For more information, please check Lauri's latest blog post on the topic. Additionally, I will discuss this further in my upcoming DrupalCon Portland keynote in a few weeks.

Drupal Core News: Working toward an Experience Builder

Planet Drupal - Tue, 2024-04-23 11:51

At DrupalCon Lille 2023, Dries announced a new strategic initiative to build a Next Generation Page Builder. The goal of the initiative was to improve and expand Layout Builder to provide a truly intuitive out-of-the-box page building experience.

We have started defining what experience would look like by identifying user journeys from beginning to end, from customizing Drupal to match a brand and content strategy to creating and editing pages. We have identified that to provide the desired experience, we need to define a standardized way for builders and creators to transform designs into optimized digital experiences. To realize the Ambitious Site Builder vision announced by Dries in 2022, we are providing visual, browser-based tools that require minimal technical expertise. This will make it easier for users without prior knowledge about Drupal or coding to implement a digital experience with Drupal. Our working name for this is Experience Builder to highlight that the module seamlessly integrates a page builder and a theme builder.

With the Experience Builder, site builders can create fully customized pages and themes using no-code/low-code tools in the browser. It provides site builders, developers, and content creators a single platform to collaborate. Content creators are empowered to create and update content without having to reach out to a developer. Site builders can balance brand consistency and creative freedom by selecting which visual editor controls to expose to the content creator. As a result, anyone in your organization can easily build and update sites, accelerating time to market while remaining brand compliant.

To keep the out-of-the-box experience simple for non-technical users, Drupal will continue to optimize the experience for site builders without the need of building custom, code-based headless front ends. We are actively exploring ways for Drupal to enable JavaScript developers to work with Drupal without the need of managing a large custom code base. Meanwhile, we will still deliver capabilities that enable headless use cases and retain much of the work that has been done to enable headless use cases so far.

How should we build the Experience Builder?

The Drupal core committer team has decided to expand on our existing solutions. Incorporating the best features of Paragraphs into an expanded Layout Builder will provide a solution that can significantly surpass the existing options explored. We are still evaluating if there are smaller components that exist in other open source projects that could be utilized by the Experience Builder.

What options did we consider?

We researched the existing Drupal based page building solutions, as well as other open source projects to decide how we should realize the Experience Builder. We evaluated Paragraphs, Layout Builder, and Gutenberg using six criteria: expertise required to realize our vision, effort required to realize our vision, effort required to migrate existing sites, future-proofness of the solutions, how well it matches with our persona, and ability for market differentiation.

Gutenberg was the primary option that we considered adopting from outside the Drupal ecosystem. With the help of the Pitchburgh fund, I had couple long days of working sessions with a group of Gutenberg maintainers, as well as the team behind Drupal Gutenberg. We learned that there are many parallels between the problems the different teams are aiming to solve. However, Gutenberg is primarily built for the content creators, which is at odds with our promise to build a platform for the Ambitious Site Builders. Gutenberg would provide us a fast way to enable content creators, but would slow us down delivering on our vision for site builders.

From the Drupal-based solutions, Paragraphs has the largest user base. Site builders attribute this to its relative simplicity and flexibility to implement nearly any kind of design system. However, Paragraphs focuses solely on component composition and content composition, and therefore doesn't enable non-technical builders to control the display of structured data, or the page as a whole.

Layout Builder originally focused on providing site builders with a way to display structured data from entities using more complex layouts. For this reason, the out-of-the-box experience hasn't been optimized for content creation. As a result, some sites using Paragraphs also choose to use Layout Builder as a tool for builders to customize the page layout, leading to a less integrated UX.

All of the solutions we evaluated came with trade-offs. The core committer team decided to prioritize how well the solution would match with our Ambitious Site Builder persona and having an ability for market differentiation. Based on our research, evolving Layout Builder, and enhancing it with capabilities that exist in Paragraphs today best meets these criteria. This approach requires a lot of expertise and effort to realize our vision, in particular UX design, but makes it easier to migrate existing sites and integrate with other Drupal APIs and use cases.

Next steps

We have identified three lanes of work to implement the Experience Builder:

  1. Creating a revamped user experience that is optimized for creating pages using components, as well as defining the layout for structured data.
  2. Implementing a new mechanism for defining components, alongside blocks. Components can be defined through the UI as no-code components, or as code components. The experience for creating code components will be similar to Single Directory Components.
  3. Implementing a browser-based theme builder that enables site builders to implement themes custom to brand without leaving the browser.
Expected timeline and call for help

The core committer team is convinced that a unified Experience Builder is one of the most important initiatives we can undertake. We are committed to moving quickly and iterating rapidly, but we need your support to succeed. We know that with the help of the community, we are able to develop a proof of concept and demo of the new user experience later this year. The first release as a contributed module is targeted for the first half of 2025.

If you are willing to help fund this project, you can reach out to Lauri or Dries. If you are willing to help with the implementation itself, we are planning to set up a recurring meeting. Join the #layouts channel on Drupal Slack for updates and opportunities to contribute!

DrupalEasy: cspell and drupalorg CLI: two useful tools for Drupal contrib module maintainers

Planet Drupal - Tue, 2024-04-23 08:34

While preparing the recent Markdown Easy 1.0.1 release, I utilized a couple of tools that I hadn't used before in order to help improve code quality as well as the quality of the release notes.


cspell is a Node.js spell-checker for code that was made available to the default Drupal GitLab templates in February, 2024. There is a new SKIP_CSPELL variable that can be set if you'd like your project to completely ignore cspell (it is enabled by default.) Documentation on using cspell in Drupal GitLab pipelines is available. I'd wager that most Drupal contrib maintainers will have the need for a custom word list (as I did,) so I took a few minutes to learn a bit more about it.

Cspell uses its default wordlist along with a few add-on dictionaries related to Drupal development (anecdotally, words like "mglaman," "gloop," "skynet," and "vampirize" are included) for checking the spelling of both variable names as well as code comments, but luckily, additional words (and patterns) can be added on a per-project basis in order to achieve a clean cspell report in GitLab pipelines. While there are several methods to add a list of custom words, the way I felt was most elegant (and easy for me to remember in the future!) was to add a .cspell-project-words.txt file on the project root (in this case, the contrib module is the project.) This file then includes a list of words that cspell should not flag as misspellings. For the Markdown Easy project, I went with "Anello," "~commonmark," and "~ultimike" (possibly for obvious reasons.) The ~ modifier indicates those words are case-insensitive (additional modifiers are available.) With that change, Markdown Easy now earns a passing score from the cspell pipeline. 

drupalorg CLI

drupalorg is a command-line interface maintained by (who else?) Matt Glaman. I actually learned about this tool a few years ago after Matt blogged about it, but for whatever reason, I only thought about installing and (finally) using it recently. The general idea is to provide a command line tool for contributors to interact with drupal.org. It's available commands are:

help Displays help for a command list Lists commands cache cache:clear (cc) Clears caches ci drupalci drupalci:list (ci:l) Lists test results for an issue drupalci:watch (ci:w) Watches a Drupal CI job issue issue:apply Applies the latest patch from an issue. issue:branch Creates a branch for the issue. issue:interdiff Generate an interdiff for the issue from local changes. issue:link Opens an issue issue:patch Generate a patch for the issue from committed local changes. maintainer maintainer:issues (mi) Lists issues for a user, based on maintainer. maintainer:release-notes (rn, mrn) Generate release notes. project project:issues (pi) Lists issues for a project. project:kanban Opens project kanban project:link Opens project page project:release-notes (prn) View release notes for a release project:releases Lists available releases tci travisci travisci:list (tci:l) Lists Travis Ci builds for a Drupal project travisci:watch (tci:w) Watches a Travis CI job

The maintainer:release-notes command is especially helpful to automatically generate release notes for a new version of a Drupal contrib project. Here's how I installed and used this tool to generate the release notes for Markdown Easy 1.0.1:

  1. I downloaded the drupalorg.phar to a new ~/sites/drupalorg/ directory on my local, and renamed the file to just drupalorg.
  2. I then gave execute permission to this file via chmod u+x ~/sites/drupalorg/drupalorg
  3. I use zsh, so I added the following to my ~/.zshrc file and then restarted my terminal:

    # drupalorg command line tool export PATH="/Users/michael/sites/drupalorg:$PATH"
  4. Here's the important part - I then navigated to my local, working copy of the Markdown Easy module. In my case cd ~/sites/d10/web/modules/contrib/markdown_easy 
  5. I then ran the following command to generate the release notes: drupalorg maintainer:release-notes 1.0.0  

I assumed at first that I should use the current release (1.0.1) as the argument, but after reading the documentation, I discovered that the command will generate release notes from the tag provided in the argument.

I also originally assumed that the command would take a contrib module's machine name as an argument, but after a few minutes of poking around the documentation, I realized that the command must be run from the module's directory.

You can see the automatically generated release notes here.


Both of these tools were rather easy to implement (once I read just a little bit of documentation) and seem like they'll be useful for just about any Drupal contrib maintainer.

PyPy: PyPy v7.3.16 release

Planet Python - Tue, 2024-04-23 08:22
PyPy v7.3.16: release of python 2.7, 3.9, and 3.10

The PyPy team is proud to release version 7.3.16 of PyPy.

This release includes security fixes from upstream CPython, and bugfixes to the garbage collector, described in a gc bug-hunt blog post.

The release includes three 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)

  • PyPy3.9, which is an interpreter supporting the syntax and the features of Python 3.9, including the stdlib for CPython 3.9.19.

  • 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 multiple release. This is a micro release, all APIs are compatible with the other 7.3 releases. It follows after 7.3.15 release on Jan 15, 2024

We recommend updating. You can find links to download the v7.3.16 releases here:


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.

What is PyPy?

PyPy is a Python interpreter, a drop-in replacement for CPython It's fast (PyPy and CPython 3.7.4 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).

  • Apple M1 arm64 machines (macos_arm64).

  • s390x running Linux

PyPy support Windows 32-bit, Linux PPC64 big- and little-endian, and Linux ARM 32 bit, 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 7.3.16 release, see the full changelog.

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

Cheers, The PyPy Team

Specbee: Improving Drupal SEO: How to Fix Duplicate Content with the Global Redirect Module

Planet Drupal - Tue, 2024-04-23 03:36
As a content writer, one thing that poses a serious concern for professionals in this field is plagiarism. It refers to the act of using someone else’s work and calling it your own. It can be frustrating and is ethically and legally unacceptable. Duplicate content is no less than plagiarism. In fact, it can cause concerns not only for content professionals but also for website owners and SEO professionals. Surprisingly, 25-30% of the content on the internet today is duplicated without people even realizing it. In this blog, we’ll talk about duplicate content, the significance of this issue in today’s metrics, and how Drupal helps you solve the problem with convenience. What is duplicate content Duplicate content simply means identical content that exists across various URLs on the internet. When identical content shows up on different URLs, search engines typically face confusion in determining which URL to prioritize in their search results. This leads to low-ranking issues for all the URLs that display similar content, while preference slides over to alternative web pages. Why is it a significant problem As mentioned earlier, duplicate content can cause issues for marketers, website owners, and SEO professionals. Let me categorize the types of issues it can bring you: For Search Engines Identification: Search engines struggle to determine which version(s) of content to include or exclude from their indexes. Link Metrics Distribution: They face uncertainty in distributing link metrics like trust, authority, anchor text, and link equity among multiple versions or a single page. Ranking Ambiguity: It becomes unclear which version(s) should rank for specific search queries. For Website Owners Search Engine Optimization: To enhance user experience, search engines tend to display only one version of duplicated content. This reduces the visibility of all duplicates. Link Equity Dilution: Inbound links are divided among duplicates rather than consolidating on one page. This disperses the link equity, affecting the search visibility of the content piece. Consequently, duplicated content fails to achieve the search visibility it could otherwise attain. What causes duplicate content Now that you’ve gathered some information about the seriousness of the issue of duplicate content, here are a few potential and technical causes that lead to content duplication. URL Parameters: This issue arises when you apply URL parameters or tracking in your website’s code. According to Google, these URL variations are created by pairing a key and a value which are separated by an equal sign, and linked by an ampersand. Consequently, although the URLs may seem distinct, users end up on the same page regardless of the link they click. Session IDs: Similar to applied URL parameters, session IDs are assigned different IDs within the URL to each user visiting your site. Multiple Versions of Your Site: This issue arises with websites that have both a www.example.com and an example.com version of their pages. It also applies to sites with an SSL certificate that maintain both HTTP and HTTPS versions of their site. Faceted Navigation: Faceted or filtered navigation allows users to refine details on your site to find the information they are looking for. It enables them to customize their search experience. However, search engines may perceive these filtered URL results as duplicated content. Types of duplicate content Duplicate content affects your SEO ranking. Having said that, in terms of search engine optimization, duplicate content is of two different types:    1. Site-wide/Cross-domain Duplicate Content Site-wide duplicate content occurs when identical or similar content is available across different pages within the same website or across multiple domains. For instance, some e-commerce platforms may use similar product descriptions on their primary domain (store.com), mobile version (m.store.com), or localized domain versions like store.ca. Such duplication of content challenges your SEO ranking.  If the duplicate content extends beyond a single website to multiple websites, determining the organic search result becomes a challenging task, requiring specific strategies to deal with the same.    2. Copied Content/Technical Problems This sounds like an oversight yet a major issue at that. Such duplicate content occurs from directly copying content to multiple locations or due to technical issues that result in the display of similar content on various URLs. This may be the case with URLs with parameters lacking canonical tags, duplicate pages without the no index directive, and copied content published without proper redirection.  When canonical tags or redirects are not appropriately set up, search engines may index and attempt to rank nearly identical versions of pages, leading to potential SEO complications. How Can Google Help Detect Duplicate Content One of the most popular and verified methods of assessing duplicate content is by simply selecting a few words from the site, enclosing them within quotes, and inputting them into Google search.  Ideally, this test on any page from your website should show your webpage in the search results, without other entries. However, if other websites also appear along with yours, Google considers the top results to be the original source of content. If you don’t find your webpage on top of the results, it might be a concern of duplicate content. You can repeat this procedure by testing several short, random sentences from your webpage using Google. Additionally, there are various free tools to check for duplicate content over the web, such as Copyscape, Plagspotter, Duplichecker, Smallseotools, and more. The Global Redirect Module: Fixing Duplicate Content SEO Issues in Drupal For those who’re unaware, Drupal is an open-source content management system that works towards simplifying development and creation processes for its global community. It offers many core and contributed modules that serve its purposes. One such module works towards fixing the issue of duplicate content - the Global Redirect Module.  The Global Redirect module is an SEO-friendly module that offers you a user-friendly interface to manage your URL path redirects. In Drupal, the alias system can sometimes lead to duplicate URLs, which can affect your website's search engine ranking. This Drupal module tackles this issue by checking for existing aliases and redirecting to the correct URL. Additionally, it manages URL formatting by removing trailing slashes, ensuring clean URL usage, and verifying node permissions and access. As per the module’s documentation source, here’s what it does to correct/fix duplicate content: Verifies if the current URL has an alias and performs a 301 redirect to it if it's not currently in use. Checks for a trailing slash in the current URL, then removes it if found, and repeats the first check with the updated request. Determines if the current URL matches the site's front page and redirects to the front page if there's a match. Ensures that Clean URLs are enabled and confirms whether the current URL is accessed using the clean method rather than the unclean method. Validates access to the URL; if the user lacks access to the path, no redirects occur. This feature helps protect private aliased nodes from exposure. Enforces the case sensitivity of the accessed URL to match the one set by the author/administrator. In non-technical interpretation of the above information, the Drupal Global Redirect module  Establishes fresh redirects. Detects faulty URL paths (ensure the “Redirect 4040” sub-module is activated for this feature). Configures redirects at the domain level (utilize the “Redirect Domain” sub-module for this purpose). Imports existing redirects. This way, you avoid the risk of having the very same content displayed on multiple URL paths. How to Configure the Global Redirect Module Before you configure the module, make sure to download it from https://www.drupal.org/project/globalredirect and then proceed with the following steps to configure the module to fix the issue of duplicate content on your Drupal site: Navigate to the Configuration page in your Drupal dashboard. In the Search and Metadata section, click on the URL redirects option. If you don’t find it, try clearing your Drupal cache and check again. On the URL redirects page, find the list of created redirects. Click on the +Add redirect button to add a new redirect. In the Path field, enter the old title or URL alias that you want to redirect from. In the To field, specify the relative internal path or the absolute external path that you want the old URL to redirect to. Choose the appropriate Redirect status from the drop-down menu. Click on Save at the bottom of the page to save the redirect configuration. Navigate to the Settings tab at the top of the page to access additional configuration options for the Global Redirect module. In the Settings tab, modify the default redirect status and adjust global redirect settings as needed.Click on Save Configuration to apply the new settings. Final Thoughts To wrap up, duplicate content affects your search engine rankings and impacts user experience as well as link equity distribution. It poses threatening challenges for content creators, website owners, and SEO professionals. Understanding the causes and types of duplicate content can help devise effective strategies to fix this issue. In Drupal, the Global Redirect module offers a convenient solution to manage URL redirects and prevent duplicity of content. While there are many other ways to boost your SEO ranking, Drupal users trust this module to work best in fixing duplicate content issues. It ensures clean URLs, proper redirection, and improved SEO performance on your Drupal site. So, employ effective measures to rank your Drupal website - avoid duplicate content, stick with Google algorithms, stay up-to-date with the latest technological measures, or you could connect with an expert Drupal development agency to enhance your Drupal SEO and boost your site’s search engine ranking.

Django Weblog: An open letter regarding the DjangoCon Europe CfP

Planet Python - Mon, 2024-04-22 18:32

As many of you are not doubt aware there have recently been some community conversation regarding a license agreement that was published as part of the DjangoCon Europe Call for Proposals for organizers. I believe it is fair to characterize the reaction as negative, with expressions of anger, frustration, and confusion towards the DSF for placing burdensome and one sided requirements for hosting a DjangoCon Europe.

I want to state first and foremost that I added the licensing agreement to the CfP. My deepest apologies for everyone who felt betrayed by it. I hold our conference organizers in the highest regard, for the equity, effort, blood, sweat, and tears they put into creating amazing community events that bring us all together. I considered resigning from the board for the pain and confusion that I have caused. I have not because I want to be part of finding a way forward and keeping DjangoCon Europe the calendar event that so many of us eagerly await. It will be up to all of you if I can be part of that journey back.

The most difficulty accusation to face is that of a lack of transparency and surprising former and prospective organizers with the license. It is difficult for me because I honestly believed I was increasing the level of transparency to organizers. This licensing agreement is not a new document, though I now understand that it is new to, well, everyone. The license has existed in the DSF legal documents repository since at least 2016 and has been signed for at least one DjangoCon Europe. In my years on the board prior to my presidency on several occasions there were todos to have selected organizers "sign the organizer contract". In addition I know that DEFNA is party to an almost identical licensing contract with the DSF. It was my intention to provide to potential organizers with the contract prior to making a proposal so that when a proposal was selected the organizers would not be taken aback when being presented with the license.

I was mortified when I heard, first in private and then publicly, that no DjangoCon Europe organizers of current memory had ever signed the license. The group of some of our community's most dedicated volunteers felt like with the click of a keyboard had turned into an arms length transaction among lawyers. At the same time I was mortified at the potential legal jeopardy the DSF had unknowingly been in by not having license agreements in place for all DjangoCons.

I'd like to touch on several points brought up in the discussion that has come from this.

The first regards the time window of DjangoCon Europe as laid out in the CfP. The DSF has long standing agreements with the PSF, DEFNA, and EuroPython to not adversely impact each other's conferences by scheduling them too close together. The agreement specifies that no two conferences should be within a month of each other. The sentiment of the agreement is well placed, but I believe it is time to revisit it. With new conferences coming into the fold (it was rightly pointed out the DjangoCon Africa is not mentioned in the license), the ability for conferences to have meaningful remote participation, and a calendar that due to weather often has the four stated conferences vying for a 5-7 month slot the one month gap is difficult to plan around. I am publicly proposing here that the interested parties to this agreement modify it such that the one month window apply to either region or theme, but not both. That would have, for instance, DjangoCon US avoiding Pycon and DjangoCons Europe and Africa but not EuroPython and vice versa.

The second point is in regards to the requirement to not schedule against major religious and cultural holidays. While I did not write that, I embody it. My first DjangoCon was DjangoCon Europe. I was unable to attend DjangoCon US in Chicago while I was living in Chicago as it had been partly scheduled against Rosh Hashanah. So I convinced my boss to send me to France instead and fell in love with the Django community.

Finally to the comments that the DSF does not care about organizers and has no interest in helping them put on a conference. Unfortunately DSF does not have inherent knowledge of running conferences, no legal entity outside the US to bring to bear, or the finances to backstop a DjangoCon. We ask for your help every year to run DjangoCon Europe because, quite simply, we can't. There was a meeting in Edinburgh of former organizers to discuss how organizing a DjangoCon Europe coule be improved. That meeting was the start of the European Organizers Support working group. It did take time to get started. We have it now. It is the sincerest hope of all of us that it is the first step in improving the experience of European organizers, and hopefully others down the line. It is a slow process, but one I dearly hope bears fruit.

I sincerely hope that we can all together still work to make DjangoCon Europe 2025 a reality. I will do all that I can to make that happen, if you will continue to have me. I do not participate in social media, but have started a thread on the Django Forum to continue this discussion. For most of the next week I will be unavailable due to the Passover holiday but it was imperative to me that I get this message to you all as soon as I could.

Thank you for your time, and for letting me serve you, Chaim Kirby President, Django Software Foundation

parallel @ Savannah: GNU Parallel 20240422 ('Børsen') [stable]

GNU Planet! - Mon, 2024-04-22 17:12

GNU Parallel 20240422 ('Børsen') has been released. It is available for download at: lbry://@GnuParallel:4

Quote of the month:

  I’m a big fan of GNU parallel!
    -- Scott Cain @scottjcain@twitter
New in this release:

  • Bug fixes and man page updates.

GNU Parallel - For people who live life in the parallel lane.

If you like GNU Parallel record a video testimonial: Say who you are, what you use GNU Parallel for, how it helps you, and what you like most about it. Include a command that uses GNU Parallel if you feel like it.

About GNU Parallel

GNU Parallel is a shell tool for executing jobs in parallel using one or more computers. A job can be a single command or a small script that has to be run for each of the lines in the input. The typical input is a list of files, a list of hosts, a list of users, a list of URLs, or a list of tables. A job can also be a command that reads from a pipe. GNU Parallel can then split the input and pipe it into commands in parallel.

If you use xargs and tee today you will find GNU Parallel very easy to use as GNU Parallel is written to have the same options as xargs. If you write loops in shell, you will find GNU Parallel may be able to replace most of the loops and make them run faster by running several jobs in parallel. GNU Parallel can even replace nested loops.

GNU Parallel makes sure output from the commands is the same output as you would get had you run the commands sequentially. This makes it possible to use output from GNU Parallel as input for other programs.

For example you can run this to convert all jpeg files into png and gif files and have a progress bar:

  parallel --bar convert {1} {1.}.{2} ::: *.jpg ::: png gif

Or you can generate big, medium, and small thumbnails of all jpeg files in sub dirs:

  find . -name '*.jpg' |
    parallel convert -geometry {2} {1} {1//}/thumb{2}_{1/} :::: - ::: 50 100 200

You can find more about GNU Parallel at: http://www.gnu.org/s/parallel/

You can install GNU Parallel in just 10 seconds with:

    $ (wget -O - pi.dk/3 || lynx -source pi.dk/3 || curl pi.dk/3/ || \
       fetch -o - http://pi.dk/3 ) > install.sh

GNU sql aims to give a simple, unified interface for accessing databases through all the different databases' command line clients. So far the focus has been on giving a common way to specify login information (protocol, username, password, hostname, and port number), size (database and table size), and running queries.

The database is addressed using a DBURL. If commands are left out you will get that database's interactive shell.

About GNU Niceload

GNU niceload slows down a program when the computer load average (or other system activity) is above a certain limit. When the limit is reached the program will be suspended for some time. If the limit is a soft limit the program will be allowed to run for short amounts of time before being suspended again. If the limit is a hard limit the program will only be allowed to run when the system is below the limit.
