Corrections
Last updated: 24 October 2026
Technical content goes stale. A library changes, an API is renamed, or an explanation that made sense in draft turns out to be wrong. We would rather fix a page and say so than quietly leave it online.
Report a correction
Email contact@nexgencoders.com with:
- The page URL.
- The sentence, code sample or diagram that is wrong.
- What you believe is correct, and a source if you have one.
A one-line message is enough. You do not need to write a full report.
What happens next
- We acknowledge corrections within two working days.
- Factual corrections are usually published within five working days.
- If the fix is substantive, we add a note to the page and an entry to the log below.
- If we cannot verify the correction, we tell you and leave the original text rather than replacing it with another unverified claim.
Correction log
| Date | Page | Change |
|---|---|---|
| 24 October 2026 | Challenge test runner (all learning paths) | Test cases were being passed to the sandbox as stdin instead of being called as expressions. The runner now evaluates the case and compares the returned value. Failures also show the actual output. |
| 24 October 2026 | Amazon Bedrock AgentCore: Your First Agent | Replaced a six-box deployment diagram that was unreadable at card width with a four-stage diagram, and corrected low-contrast labels on the orange and green nodes. |
| 24 October 2026 | Concept Bites: DNS, JWT and HTTPS | Replaced generic explanations with reviewed copy. Removed an example IP address from the DNS explanation and resolved a contradiction about JWT revocation. |
| 24 October 2026 | Learning-path article bodies | Rewrote the article prose to remove filler and repeated phrasing. Code blocks, tables and diagrams were preserved and checked against the originals. |
Scope
This log covers substantive corrections to lessons, articles, challenges and diagrams. Typos, broken links and formatting fixes are made without an entry. If a page is removed because it can no longer be kept accurate, the removal is noted here.
