You are the site manager pointing at the wall and saying, "Build that higher."" If someone would (a very dumb person) kickstart a construction company by hiring random "average joe" people to do what he says, and google everything about it before you do, and he was "just" a guy who thinks big buildings are cool (like everyone is "just" something).

Vulnerabilities in artificial intelligence platforms: the example of XSS in Mintlify and the dangers of supply chain attacks
https://www.reddit.com/r/programming/comments/1pqpt6s/vulnerabilities_in_artificial_intelligence/

<!-- SC_OFF -->The flaw discovered in this article arose from an endpoint that served static resources without validating the domain correctly, allowing Cross-Site Scripting (XSS) on large customer websites. Although it was not a case of 'AI-generated' code being executed at runtime, the platform itself is powered by AI. This raises a larger concern: even when LLMs do not directly create vulnerable code, the AI ecosystem in general accelerates the adoption and integration of third-party tools, prioritizing speed and convenience, often at the expense of thorough security analysis. Such rapid integrations can lead to critical flaws, such as inadequate input validation or poor access controls, creating a favorable environment for supply chain attacks. Research shows that code generated by LLMs often contains common vulnerabilities, such as XSS, SQL injection, and missing security headers. This leads to a reflection: does this happen because the models are trained on billions of lines of old code, where insecure practices are common? Or is it because LLMs prioritize immediate functionality and conciseness over the robustness of the security architecture? <!-- SC_ON --> submitted by /u/Fragrant-Age-2099 (https://www.reddit.com/user/Fragrant-Age-2099)

Engineering Lessons from 12 Projects Shipped in 2025
https://www.reddit.com/r/programming/comments/1pqtia4/engineering_lessons_from_12_projects_shipped_in/

<!-- SC_OFF -->In 2025, engineers on our team shipped projects across growth, payments, content creation, analytics, and infrastructure. Some of this work was user-facing, other projects were migrations and rewrites that paid down years of technical debt. Across the board, the hardest problems involved breaking long-standing assumptions, navigating legacy systems, or making explicit tradeoffs between product outcomes, performance, and velocity. We generalized our learnings through a collection of short engineering case studies framed around the practical challenges of building and maintaining production software: https://www.patreon.com/posts/year-in-review-146102084 <!-- SC_ON --> submitted by /u/patreon-eng (https://www.reddit.com/user/patreon-eng)
