It cites a METR study showing experienced developers were 19% slower with AI tools while believing they were 20% faster, and a Veracode finding of security flaws in about 45% of AI-generated code samples. The piece ends with a sponsored pitch for Spacetime, an all-in-one backend platform claiming up to 1000x faster data access by colocating database and server. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How much slower were experienced developers when using AI tools according to the METR study? Experienced open-source developers working on their own codebases with AI tools ended up 19% slower, even though they believed they were 20% faster. The study, run by METR, highlights a gap between perceived and actual productivity gains from AI coding assistants. _Developers weighing real AI productivity gains against the hype can track findings like this on daily.dev._ ### What percentage of AI-generated code contains security flaws according to Veracode's testing? Veracode found security flaws in roughly 45% of AI-generated code samples it tested. This is cited as a reason developers should read every line of AI-suggested code before merging it rather than trusting it outright. _Anyone reviewing AI-generated code for security risks can follow coverage like this on daily.dev._ ### What book is recommended for learning distributed systems concepts like the CAP theorem? Designing Data-Intensive Applications by Martin Kleppmann is recommended as the best map of distributed systems fundamentals, including the CAP theorem's tradeoff between consistency and availability when a network partition occurs. It's described as dense but the single best resource for understanding how backend systems fit together at scale. _Engineers building a system design reading list can find recommendations like this on daily.dev._ ## Community discussion Top comments from developers on daily.dev. **@harshitmanepally** · 4 upvotes > Need more of this. **@ristotoldsep** · 1 upvotes > SQL, debugging and rollback plans. boring skills keep winning. **@micahnorwoodjordan** · 1 upvotes > yup, the good ol' fundamentals **@deepjoshi\_dev** · 0 upvotes > Pretty much what I do nowadays. **@andruhudz** · 0 upvotes > Does anyone has a real list of skills of source with skills to use? > For example: [https://github.com/vercel-labs/agent-skills/tree/main](https://github.com/vercel-labs/agent-skills/tree/main) ## Similar posts on daily.dev - [Java Developers Are Using AI Wrong.
