Link Checker Report Discussion

Hey everyone! This is a breakdown of the link checker report for our Rust training materials. Let's dive in and make sure everything's pointing where it should be.

Summary

Here's the big picture:

Status Count
🔍 Total 255
✅ Successful 228
⏳ Timeouts 0
🔀 Redirected 21
👻 Excluded 4
❓ Unknown 0
🚫 Errors 2
⛔ Unsupported 0

Overall, things look pretty good! Most links are working fine. However, we do have a few errors and redirects we need to address. Let's get into the details.

Deep Dive into the Summary Table

The summary table gives us a bird's-eye view of the health of the links within our Rust training materials. The Total count of 255 represents the aggregate number of links that the checker has assessed. A significant portion, 228 links, falls under the Successful category, indicating that these URLs are active and lead to the intended destination without any issues. This reflects positively on the stability and accuracy of the content. The Redirected count of 21 suggests that these links, while functional, have undergone a change in their address and now point to a new URL. While redirects are generally harmless, they can impact the user experience slightly due to the extra time it takes to reach the final destination. Additionally, it's a good practice to update these links to the direct address to avoid unnecessary hops. The Excluded count of 4 indicates links that were intentionally skipped from the checking process, possibly due to configuration settings or specific rules defined in the link checker. The Unknown count of 0 is ideal, as it signifies that the checker encountered no links with indeterminate status. On the other hand, the Errors count of 2 is a point of concern, suggesting that these links are broken or lead to an error page. Addressing these errors is crucial to maintain the integrity of the training materials. Finally, the Unsupported count of 0 indicates that no links were found to be of an unsupported type, meaning that all protocols and formats are compatible with the link checker. Regular monitoring and maintenance based on these metrics can significantly improve the usability and reliability of the Rust training resources.

Errors per input

Okay, these are the ones we really need to fix!

Errors in slides/2_3-advanced-syntax.md

Uh oh, a 503 error! This means the server is temporarily unavailable. Let's check if the server is back up. If not, we might need to host the file elsewhere or find an alternative resource. We need to keep the advanced syntax accessible, so let's prioritize this.

Errors in slides/6_1-foreign-function-interface.md

Another 503! Looks like faultlore.com is having some issues. This image is used in the foreign function interface section, so let's find a backup image or host it ourselves. It's important that the visual aid is available to the students, so let's not delay on this.

Diving Deeper into Error Analysis

When scrutinizing the errors flagged by the link checker, it's essential to contextualize them within the framework of the Rust training materials. In the case of the error in slides/2_3-advanced-syntax.md, the 503 status code suggests that the server hosting advanced-syntax.html is either overloaded or undergoing maintenance. This could potentially disrupt the learning experience for students who rely on this resource to understand complex syntax concepts. Therefore, it's imperative to promptly investigate the server status and, if necessary, explore alternative hosting solutions or mirror the content on a more reliable platform. Addressing this issue ensures uninterrupted access to critical information. Similarly, the error encountered in slides/6_1-foreign-function-interface.md, where the image abi-kiss.png is unavailable due to a 503 status code, highlights the vulnerability of relying on external resources. Since visual aids play a crucial role in illustrating the intricacies of the foreign function interface, the unavailability of this image could hinder comprehension. In such cases, it's advisable to either host the image locally or find a stable alternative to prevent future disruptions. Proactive management of these errors not only enhances the user experience but also demonstrates a commitment to providing high-quality, reliable training materials. Furthermore, documenting the steps taken to resolve these errors can serve as a valuable reference for future troubleshooting and maintenance efforts.

Redirects per input

These links are still working, but they're taking an extra hop. Let's update them to point directly to the final destination.

Redirects in book/src/async-on-embedded.md

Let's change the link to https://docs.rs/lsm303agr/latest/lsm303agr/. This is simple enough.

Redirects in book/src/crate-engineering.md

Update all these to their /latest versions.

Redirects in book/src/instructions.md

Update these to the final destination URLs. Especially the VS Code and Cargo links, as they had two redirects!

Redirects in book/src/introduction.md

Update this to https://tweedegolf.nl/en/expertise/rust/training. Nice to see it eventually gets to the right place!

Redirects in book/src/rust-for-web.md

Update to https://docs.rs/axum/latest/axum/.

Redirects in book/src/rust-from-python.md

Update to https://rust-lang.org/tools/install/.

Redirects in book/src/wrap-up.md

Update to the final Google Forms link.

Redirects in slides/3_1-crate-engineering.md

Update both to https://docs.rs/url/latest/url/. Seems like a common pattern here.

Redirects in slides/4_3-asynchronous-multitasking.md

Update to https://docs.rs/tracing/latest/tracing/.

Redirects in slides/7_1-rust-from-python.md

Update to https://pyo3.rs/v0.27.1/.

Redirects in slides/7_2-async-rust-python.md

Update to https://pyo3.rs/v0.27.1/.

Redirects in slides/8_4-embassy-framework.md

Update these Embassy links to their final destinations.

A Closer Look at Redirect Analysis

Analyzing the redirects within our Rust training materials reveals valuable insights into the longevity and maintainability of external links. The presence of redirects indicates that the original URL has been changed or updated, necessitating a redirection to the new location. While redirects ensure that users eventually reach the intended content, they introduce an additional step in the process, which can impact the user experience, especially for users with slower internet connections. Therefore, it's best practice to update these links to point directly to the final destination. In the context of book/src/async-on-embedded.md, the redirect from https://docs.rs/lsm303agr to https://docs.rs/lsm303agr/latest/lsm303agr/ suggests that the crate documentation has been updated to a newer version. Similarly, the redirects in book/src/crate-engineering.md for crates like anyhow, clap, serde, and serde_json indicate updates to their respective documentation. Addressing these redirects involves updating the links to the /latest versions, ensuring that students have access to the most current information. Furthermore, the redirects in book/src/instructions.md for resources like the VS Code Live Share, Cargo documentation, and Nordic Semiconductor's nRF52833 datasheet highlight the importance of monitoring external links for changes. Regularly updating these links ensures that students are directed to the correct resources without unnecessary delays. Similarly, the redirect for the Tweedegolf workshops page in book/src/introduction.md underscores the need to maintain accurate and up-to-date information about the training programs. By proactively managing redirects, we can enhance the user experience and maintain the credibility of our Rust training materials.
