Continuous Integration and Continuous Delivery (CI/CD) pipelines are the backbone of modern software development, automating the process of building, testing, and deploying applications. However, as these pipelines grow in complexity, they often become difficult to maintain, debug, and port across different execution platforms, frequently relying on verbose and platform-specific YAML configurations. Jean-Christophe Sirot, in his presentation, introduced Dagger as a revolutionary approach to CI/CD, allowing pipelines to be written as code, executable locally, testable, and portable. He explored Dagger Functions and Dagger Modules as key concepts for creating and sharing reusable, language-agnostic components for CI/CD workflows, positioning Dagger as a versatile “Swiss Army knife” for modernizing these critical pipelines.

The Pain Points of Traditional CI/CD

Jean-Christophe began by outlining the common frustrations associated with traditional CI/CD pipelines. Relying heavily on YAML or other declarative formats for defining pipelines can lead to complex, repetitive, and hard-to-read configurations, especially for intricate workflows. Debugging failures within these pipelines is often challenging, requiring pushing changes to a remote CI server and waiting for the pipeline to run. Furthermore, pipelines written for one CI platform (like GitHub Actions or GitLab CI) are often not easily transferable to another, creating vendor lock-in and hindering flexibility. This dependency on specific platforms and the difficulty in managing complex workflows manually are significant pain points for development and DevOps teams.

Dagger: CI/CD as Code

Dagger offers a fundamentally different approach by treating CI/CD pipelines as code. It allows developers to write their pipeline logic using familiar programming languages (like Go, Python, Java, or TypeScript) instead of platform-specific configuration languages. This brings the benefits of software development practices – such as code reusability, modularity, testing, and versioning – to CI/CD. Jean-Christophe explained that Dagger executes these pipelines using containers, ensuring consistency and portability across different environments. The Dagger engine runs the pipeline logic, orchestrates the necessary container operations, and manages dependencies. This allows developers to run and debug their CI/CD pipelines locally using the same code that will execute on the remote CI platform, significantly accelerating the debugging cycle.

Dagger Functions and Modules

Key to Dagger’s power are Dagger Functions and Dagger Modules. Jean-Christophe described Dagger Functions as the basic building blocks of a pipeline – functions written in a programming language that perform specific CI/CD tasks (e.g., building a Docker image, running tests, deploying an application). These functions interact with the Dagger engine to perform container operations. Dagger Modules are collections of related Dagger Functions that can be packaged and shared. Modules allow teams to create reusable components for common CI/CD patterns or specific technologies, effectively creating a library of CI/CD capabilities. For example, a team could create a “Java Build Module” containing functions for compiling Java code, running Maven or Gradle tasks, and building JAR or WAR files. These modules can be easily imported and used in different projects, promoting standardization and reducing duplication across an organization’s CI/CD workflows. Jean-Christophe demonstrated how to create and use Dagger Modules, illustrating their potential for building composable and maintainable pipelines. He highlighted that Dagger’s language independence means that modules can be written in one language (e.g., Python) and used in a pipeline defined in another (e.g., Java), fostering collaboration between teams with different language preferences.

The Benefits: Composable, Maintainable, Portable

By adopting Dagger, teams can create CI/CD pipelines that are:
– Composable: Pipelines can be built by combining smaller, reusable Dagger Modules and Functions.
– Maintainable: Pipelines written as code are easier to read, understand, and refactor using standard development tools and practices.
– Portable: Pipelines can run on any platform that supports Dagger and containers, eliminating vendor lock-in.
– Testable: Individual Dagger Functions and modules can be unit tested, and the entire pipeline can be run and debugged locally.

Jean-Christophe’s presentation positioned Dagger as a versatile tool that modernizes CI/CD by bringing the best practices of software development to pipeline automation. The ability to write pipelines in code, leverage reusable modules, and execute locally makes Dagger a powerful “Swiss Army knife” for developers and DevOps engineers seeking more efficient, reliable, and maintainable CI/CD workflows.

Michael Orlitzky, a multifaceted security researcher and mathematician, captivated the DEF CON 32 audience with a provocative presentation on bypassing payment mechanisms in CSC ServiceWorks’ pay-to-play laundry machines. By exploiting physical vulnerabilities in Speed Queen washers and dryers, Michael demonstrated how to run these machines without payment, framing his actions as a response to CSC’s exploitative practices. His talk, rich with technical detail and humor, shed light on the intersection of physical security and consumer frustration, urging attendees to question predatory business models.

Uncovering CSC’s Predatory Practices

Michael began by introducing CSC ServiceWorks, a major provider of coin- and app-operated laundry machines in residential buildings. He detailed their business model, which charges tenants for laundry despite rent covering utilities, often trapping users with non-refundable prepaid cards or unreliable apps like CSC GO. Michael recounted personal grievances, such as machines eating quarters or failing to deliver services, supported by widespread customer complaints citing CSC’s poor maintenance and refund processes. His narrative positioned CSC as a corporate antagonist, justifying his exploration of hardware bypasses as a form of reclaiming fairness.

Bypassing Coin Slots with Hardware Hacks

Delving into the technical core, Michael explained how to access the service panels of CSC-branded Speed Queen machines, which use standardized keys available online. By short-circuiting red and black wires in the coin-drop mechanism, he tricked the machine into registering payment, enabling free cycles without damage. His live demonstration, complete with safety warnings about grounding and electrical risks, showcased the simplicity of the bypass—achievable in seconds with minimal tools. Michael’s approach, detailed on his personal website, emphasized accessibility, requiring only determination and basic equipment.

Addressing CSC’s Security Upgrades

Michael also addressed CSC’s response to his findings, noting that days before DEF CON 32, the company upgraded his building’s machines with new tubular locks and security Torx screws. Undeterred, he demonstrated how to bypass these using a tubular lockpick or a flathead screwdriver, highlighting CSC’s superficial fixes. His candid tone and humorous defiance—acknowledging the machines’ internet-connected logs—underscored the low risk of repercussions, as CSC’s focus on profit over maintenance left such vulnerabilities unaddressed. This segment reinforced the talk’s theme of exploiting systemic flaws in poorly secured systems.

Ethical Implications and Community Call

Concluding, Michael framed his work as a protest against CSC’s exploitative practices, encouraging attendees to consider the ethics of bypassing systems that exploit consumers. He shared resources, including manuals and his write-up, to empower others while cautioning about legal risks. His talk sparked reflection on the balance between technical ingenuity and corporate accountability, urging the DEF CON community to challenge predatory systems through informed action.

I recently started migrating my WordPress site from Free.fr to OVHcloud hosting. The migration is still in progress, but along the way I needed to enable and validate
programmatic publishing through the WordPress REST API (RPC/API calls). This post documents the full process end-to-end, including OVH-specific gotchas and troubleshooting.

My last migration was many years ago, from DotClear 2 to WordPress…

Why move from Free.fr to OVH?

• Performance: More CPU/RAM and faster PHP execution make WordPress snappier.
• Modern PHP: Current PHP versions and extensions are available and easy to select.
• HTTPS (SSL): Essential for secure logins and required for Application Passwords.
• Better control: You can tweak .htaccess, install custom/mu-plugins, and adjust config.
• Scalability: Easier to upgrade plans and resources as your site grows.

What is the WordPress REST API?

WordPress ships with a built-in REST API at /wp-json/. It lets you read and write content, upload media, and automate publishing from scripts or external systems (curl, Python, Node.js, CI, etc.).

Step 1 — Confirm the API is reachable

1. Open https://yourdomain.com/wp-json/ in a browser. You should see a JSON index of routes.
2. Optional: check https://yourdomain.com/wp-json/wp/v2 or
   https://yourdomain.com/wp-json/wp/v2/types/post to view available endpoints and fields.

Step 2 — Enable authentication with Application Passwords

1. Sign in to /wp-admin/ with a user that can create/publish posts.
2. Go to Users → Profile (your profile page).
3. In Application Passwords, add a new password (e.g., “API access from laptop”). It should look like ABCD EFgh IjKl M123 n951 (including spaces)
4. Copy the generated password (you’ll only see it once). Keep it secure.

You will authenticate via HTTP Basic Auth using username:application-password over HTTPS.

Step 3 — Test authentication (curl)

Replace the placeholders before running:

curl -i -u 'USERNAME:APP_PASSWORD' \
  https://yourdomain.com/wp-json/wp/v2/users/me

Expected result: 200 OK with your user JSON. If you get 401 or 403, see Troubleshooting below.

Important on OVH — The Authorization header may be stripped

On some OVH hosting configurations, the HTTP Authorization header isn’t passed to PHP.
If that happens, WordPress cannot see your Application Password and responds with:

{"code":"rest_not_logged_in","message":"You are not currently logged in.","data":{"status":401}}

To confirm you’re sending the header, try explicitly setting it:

curl -i -H "Authorization: Basic $(echo -n 'USERNAME:APP_PASSWORD' | base64)" \
  https://yourdomain.com/wp-json/wp/v2/users/me

If you still get 401, fix the server so PHP receives the header.

Step 4 — Fixing Authorization headers on OVH

Option A — Add rules to .htaccess

Connect in FTP, browse to “www” folder, edit the .htaccess file. Add these lines above the “BEGIN WordPress” block:

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
</IfModule>

<IfModule mod_setenvif.c>
    SetEnvIf Authorization "(.*)" HTTP_AUTHORIZATION=$1
</IfModule>

Option B — Tiny must-use plugin

Create wp-content/mu-plugins/ if missing, then add fix-authorization.php:

<?php
/**
 * Plugin Name: Fix Authorization Header
 * Description: Ensures HTTP Authorization header is passed to WordPress for Application Passwords.
 */
add_action('init', function () {
    if (!isset($_SERVER['HTTP_AUTHORIZATION'])) {
        if (isset($_SERVER['REDIRECT_HTTP_AUTHORIZATION'])) {
            $_SERVER['HTTP_AUTHORIZATION'] = $_SERVER['REDIRECT_HTTP_AUTHORIZATION'];
        } elseif (function_exists('apache_request_headers')) {
            $headers = apache_request_headers();
            if (isset($headers['Authorization'])) {
                $_SERVER['HTTP_AUTHORIZATION'] = $headers['Authorization'];
            }
        }
    }
});

Upload and reload: authentication should now succeed.

Step 5 — Create and publish a complete post via API

Optional: create a category and a tag

# Create a category
curl -i -X POST \
  -u 'USERNAME:APP_PASSWORD' \
  -H "Content-Type: application/json" \
  -d '{ "name": "Tech" }' \
  https://yourdomain.com/wp-json/wp/v2/categories

# Create a tag
curl -i -X POST \
  -u 'USERNAME:APP_PASSWORD' \
  -H "Content-Type: application/json" \
  -d '{ "name": "API" }' \
  https://yourdomain.com/wp-json/wp/v2/tags

Upload a featured image

curl -i -X POST \
  -u 'USERNAME:APP_PASSWORD' \
  -H "Content-Disposition: attachment; filename=header.jpg" \
  -H "Content-Type: image/jpeg" \
  --data-binary @/full/path/to/header.jpg \
  https://yourdomain.com/wp-json/wp/v2/media

Note the returned MEDIA_ID.

Create and publish the post

curl -i -X POST \
  -u 'USERNAME:APP_PASSWORD' \
  -H "Content-Type: application/json" \
  -d '{
        "title": "Hello from the API",
        "content": "<p>Created automatically 🚀</p>",
        "status": "publish",
        "categories": [CAT_ID],
        "tags": [TAG_ID],
        "featured_media": MEDIA_ID
      }' \
  https://yourdomain.com/wp-json/wp/v2/posts

Optionally update excerpt or slug

POST_ID=REPLACE_WITH_ID

curl -i -X POST \
  -u 'USERNAME:APP_PASSWORD' \
  -H "Content-Type: application/json" \
  -d '{ "excerpt": "Short summary", "slug": "hello-from-the-api" }' \
  https://yourdomain.com/wp-json/wp/v2/posts/$POST_ID

Troubleshooting

• 401 Unauthorized / rest_not_logged_inThe Authorization header isn’t reaching PHP. Add the .htaccess rules or the mu-plugin above. Re-test with
  -H "Authorization: Basic …".
• 403 ForbiddenThe user lacks capabilities (e.g., Authors can’t publish globally). Use "status":"draft" or run publishing as an Editor/Admin.
• Media upload failsCheck upload_max_filesize, post_max_size, and file permissions. Try a smaller file to isolate the issue.
• Categories/Tags not appliedUse numeric IDs, not names. Fetch with /wp-json/wp/v2/categories and /wp-json/wp/v2/tags.
• PermalinksPrefer non-Plain permalinks. If using Plain, you can call endpoints with the fallback:
  https://yourdomain.com/?rest_route=/wp/v2/posts.

Conclusion

Moving from Free.fr to OVH brings better performance, modern PHP, and full HTTPS, which is perfect for automation and scheduling.
After ensuring the Authorization header reaches WordPress (via .htaccess or a tiny mu-plugin), the REST API works smoothly for creating posts, uploading media, and managing taxonomy.
My migration is still ongoing, but having a reliable API in place is already a big win.

Embracing Rust’s Cross-Platform Versatility

Rust’s ability to operate seamlessly across diverse platforms—from embedded devices to web applications—positions it as a uniquely versatile language for full-stack development. At OxidizeConf2024, Anatol Ulrich, a freelance developer with extensive experience in web, mobile, and embedded systems, presented a compelling vision of the “fullest stack” built entirely in Rust. Anatol’s talk demonstrated how Rust’s “write once, compile anywhere” philosophy enables low-friction, vertically integrated projects, spanning embedded devices, cloud services, and web or native clients.

Anatol showcased a project integrating a fleet of embedded devices with a cloud backend and a web-based UI, all written in Rust. Using the postcard crate for serialization and remote procedure calls (RPC), he achieved seamless communication between an STM32 microcontroller and a browser via Web USB. This setup allowed real-time data exchange, demonstrating Rust’s ability to unify disparate platforms. Anatol’s approach leverages Rust’s type safety and zero-cost abstractions, ensuring robust performance across the stack while minimizing development complexity.

Streamlining Development with Open-Source Tools

A key aspect of Anatol’s presentation was the use of open-source Rust crates to streamline development. The dioxus crate enabled cross-platform UI development, supporting both web and native clients with a single codebase. For embedded communication, Anatol employed postcard for efficient serialization, agnostic to the underlying transport layer—whether Web USB, Web Serial, or MQTT. This flexibility allowed him to focus on application logic rather than platform-specific details, reducing friction in multi-platform projects.

Anatol also introduced a crate for auto-generating UIs based on type introspection, simplifying the creation of user interfaces for complex data structures. By sprinkling minimal hints onto the code, developers can generate dynamic UIs, a feature particularly useful for rapid prototyping. Despite challenges like long compile times and WebAssembly debugging difficulties, Anatol’s open-source contributions, soon to be published, invite community collaboration to enhance Rust’s full-stack capabilities.

Future Directions and Community Collaboration

Anatol’s vision extends beyond his current project, aiming to inspire broader adoption of Rust in full-stack development. He highlighted areas for improvement, such as WebAssembly debugging and the orphan rule, which complicates crate composition. Tools like Servo, a Rust-based browser engine, could enhance Web USB support, further bridging embedded and web ecosystems. Anatol’s call for contributors underscores the community-driven nature of Rust, encouraging developers to collaborate on platforms like GitHub and Discord to address these challenges.

The talk also touched on advanced techniques, such as dynamic type handling, which Anatol found surprisingly manageable compared to macro-heavy alternatives. By sharing his experiences and open-source tools, Anatol fosters a collaborative environment where Rust’s ecosystem can evolve to support increasingly complex applications. His work exemplifies Rust’s potential to deliver cohesive, high-performance solutions across the entire technology stack.

Silvia Puglisi and Roger Dingledine, key figures in the Tor Project, delivered an insightful presentation at DEF CON 32, shedding light on the Tor network’s metrics and community-driven efforts to maintain its health. As millions rely on Tor to evade surveillance and censorship, Silvia and Roger detailed how the Tor Project collects safe metrics, detects attacks, and fosters a vibrant relay operator community. Their talk provided a window into the challenges of sustaining an anonymity network and invited attendees to contribute to its mission of preserving internet freedom.

Collecting Safe Metrics for Anonymity

Silvia opened by explaining the Tor Project’s approach to gathering metrics without compromising user anonymity. By analyzing usage patterns and relay performance, the network health team identifies unusual activity, such as potential attacks or misconfigured relays. Silvia highlighted tools like Tor Weather, which notifies operators of relay issues, and the network status API, which supports data analysis. These efforts ensure the network remains robust while prioritizing user privacy, a delicate balance in an anonymity-focused ecosystem.

Detecting and Mitigating Network Threats

Roger delved into the strategies for identifying and countering attacks on the Tor network, which supports over seven thousand volunteer-operated relays. He discussed how metrics help detect malicious relays and unusual traffic patterns, enabling rapid response to threats. Roger cited historical examples, such as the 2009 Green Party Movement in Iran, where Tor empowered activists, underscoring the network’s role in global activism. By sharing these insights, he emphasized the importance of community vigilance in maintaining network integrity.

Fostering a Diverse Relay Community

The duo highlighted the Tor Project’s efforts to grow its community of relay operators, encouraging attendees to run relays, bridges, or Snowflake proxies. Silvia detailed initiatives like the formal relay operator meetup planned for future conferences, aiming to strengthen community ties. Roger stressed that contributing to Tor supports activists worldwide, particularly those without institutional protections. Their call to action invited DEF CON attendees to join the network health team or contribute to projects like rewriting tools in Rust for better performance.

Future Challenges and Community Engagement

Concluding, Silvia and Roger outlined ongoing challenges, such as improving data visualization and scaling the network to handle increasing demand. They encouraged contributions to the Tor Project’s wiki and open-source tools, emphasizing that every relay or code contribution aids the fight for privacy and anonymity. Their interactive session at the Tor booth post-talk invited attendees to explore further, reinforcing the collaborative spirit that drives the Tor ecosystem forward.

Go, the programming language designed by Google, has gained significant popularity for its simplicity, efficiency, and strong support for concurrent programming. A core philosophy of Go is its minimalist design and emphasis on a robust standard library, encouraging developers to “do a lot with a little.” Nathan Castelein, in his presentation, championed this philosophy, demonstrating how a significant portion of modern applications can be built effectively using only Go’s standard library, without resorting to numerous third-party dependencies. He explored various native packages and compared their functionalities to well-known third-party alternatives, showcasing why and how returning to the fundamentals can lead to simpler, more maintainable, and often equally performant Go applications.

The Go Standard Library: A Powerful Foundation

Nathan highlighted the richness and capability of Go’s standard library. Unlike some languages where the standard library is minimal, Go provides a comprehensive set of packages covering a wide range of functionalities, from networking and HTTP to encoding/decoding, cryptography, and testing. He emphasized that these standard packages are well-designed, thoroughly tested, and actively maintained, making them a reliable choice for building production-ready applications. Focusing on the standard library reduces the number of external dependencies, which simplifies project management, minimizes potential security vulnerabilities introduced by third-party code, and avoids the complexities of managing version conflicts. It also encourages developers to gain a deeper understanding of the language’s built-in capabilities.

Comparing Standard Packages to Third-Party Libraries

The core of Nathan’s talk involved comparing functionalities provided by standard Go packages with those offered by popular third-party libraries. He showcased examples in areas such as:
– Web Development: Demonstrating how to build web servers and handle HTTP requests using the net/http package, contrasting it with frameworks like Gin, Echo, or Fiber. He would have shown that for many common web tasks, the standard library provides sufficient features.
– Logging: Illustrating the capabilities of the log/slog package (introduced in Go 1.21) for structured logging, comparing it to libraries like Logrus or Zerolog. He would have highlighted how log/slog provides modern logging features natively.
– Testing: Exploring the testing package for writing unit and integration tests, perhaps mentioning how it can be used effectively without resorting to assertion libraries like Testify for many common assertion scenarios.

The comparison aimed to show that while third-party libraries often provide convenience or specialized features, the standard library has evolved to incorporate many commonly needed functionalities, often in a simpler and more idiomatic Go way.

The Benefits of a Minimalist Approach

Nathan articulated the benefits of embracing a “Go without frills” approach. Using the standard library more extensively leads to:
– Reduced Complexity: Fewer dependencies mean a simpler project structure and fewer moving parts to understand and manage.
– Improved Maintainability: Code relying on standard libraries is often easier to maintain over time, as the dependencies are stable and well-documented.
– Enhanced Performance: Standard library implementations are often highly optimized and integrated with the Go runtime.
– Faster Compilation: Fewer dependencies can lead to quicker build times.
– Smaller Binaries: Avoiding large third-party libraries can result in smaller executable files.

He acknowledged that there are still valid use cases for third-party libraries, especially for highly specialized tasks or when a library provides significant productivity gains. However, the key takeaway was to evaluate the necessity of adding a dependency and to leverage the powerful standard library whenever it suffices. The talk encouraged developers to revisit the fundamentals and appreciate the elegance and capability of Go’s built-in tools for building robust and efficient applications.

Nick Frichette, a cloud security expert, enthralled the DEF CON 32 audience with a deep dive into vulnerabilities within Amazon Web Services (AWS) that enable initial access to cloud environments. Moving beyond traditional misconfiguration exploits, Nick explored flaws in AWS services like AppSync and Amplify, demonstrating how attackers can hijack Identity and Access Management (IAM) roles. His presentation offered practical defensive strategies, empowering organizations to secure their cloud infrastructure against sophisticated attacks.

Understanding IAM Role Exploits

Nick began by explaining how IAM roles establish trust within AWS, relying on mechanisms like sts:AssumeRoleWithWebIdentity to prevent unauthorized access across accounts. He detailed a confused deputy vulnerability in AWS AppSync that allowed attackers to assume roles in other accounts, bypassing trust boundaries. Through a real-world case study, Nick illustrated how this flaw enabled unauthorized access, emphasizing the importance of understanding trust relationships in cloud environments to prevent such breaches.

Amplify Vulnerabilities and Zero-Day Risks

Delving deeper, Nick revealed a critical vulnerability in AWS Amplify that exposed customer IAM roles to takeover, granting attackers a foothold in victim accounts. His demonstration highlighted how adversaries could exploit this flaw without authentication, underscoring the severity of zero-day vulnerabilities in cloud services. Nick’s meticulous analysis of Amplify’s architecture provided insights into how such flaws arise, urging security practitioners to scrutinize service configurations for hidden risks.

Defensive Strategies for Cloud Security

Nick concluded with actionable recommendations, advocating for the use of condition keys in IAM trust policies to block cross-tenant attacks. He demonstrated how setting account-specific conditions thwarted his AppSync exploit, offering a defense-in-depth approach. Nick encouraged organizations to audit IAM roles, particularly those using web identity federation, and to test configurations rigorously before deployment. His work, available at Security Labs, equips defenders with tools to fortify AWS environments.

Dimitris Kaklamanis, a lead software engineer at CodeHub, delivered an 11-minute talk at Devoxx Greece 2025, exploring how Angular micro-frontends revolutionize scalable web development.

Micro-Frontends Unveiled

Kaklamanis opened with a relatable scenario: a growing front-end monolith turning into a dependency nightmare. Micro-frontends, inspired by microservices, break the UI into smaller, independent pieces, each owned by a team. This enables parallel development, reduces risks, and enhances scalability. He outlined four principles: decentralization (team-owned UI parts), technology agnosticism (mixing frameworks like Angular, React, or Vue), resilience (isolated bugs don’t crash the app), and scalability (independent team scaling). A diagram showed teams building features in different frameworks, integrated at runtime via a shell app.

Pros and Cons

Micro-frontends offer scalability, tech flexibility, faster parallel development, resilience, and easier maintenance due to focused codebases. However, challenges include increased complexity (more coordination), performance overhead (multiple apps loading), communication issues (state sharing), and CI/CD complexity (separate pipelines). Kaklamanis highlighted Angular’s strengths: its component-based structure aligns with modularity, CLI tools manage multiple projects, and features like lazy loading and Webpack 5 module federation simplify implementation. Tools like NX streamline monorepo management, making Angular a robust choice.

Implementation in Action

Kaklamanis demonstrated a live Angular store app with independent modules (orders, products, inventory). A change in the product component didn’t affect others, showcasing isolation. He recommended clear module ownership, careful intermodule communication, performance monitoring, and minimal shared libraries. For large, multi-team projects, he urged prototyping micro-frontends, starting small and iterating for scalability.
