HackerBooks Indexes Books Recommended in Hacker News Comments Since 2007

·1 views

A developer has launched HackerBooks, a site cataloguing roughly 16,500 books that at least two different Hacker News commenters have mentioned since 2007. Inspired by Andrej Karpathy's HackerTube, the project lets users trace each book back to the comments that referenced it. Claude, Anthropic's AI model, wrote most of the code, including the data pipeline and website, while the creator guided decisions and bought the domain. The index counts mentions rather than sentiment, so both praise and criticism contribute to a book's presence. The creator has invited users to report missing books or incorrect matches, and the dataset is available for download from the site's about page.

Unreal Engine cook logs can mislead: notes from 37 controlled runs

A developer packaged a small Unreal Engine test project and deliberately broke it in controlled, repeatable ways across Unreal Engine 5.4.4 and 5.8.3. They ran 13 clean baseline builds and 24 sabotaged runs covering six failure scenarios, such as a plugin crashing during startup and a duplicated plugin. The logs showed that the final error line is often misleading, and that the real cause sits earlier in the output. Most failures in the test (12 of 16) stopped before the cook even began, which the exit codes reveal. The author notes this covers one project on one machine with synthetic failures, so it reflects how Unreal reports errors rather than how often they occur in practice.

Masking PII Before a Chatbot Replies: A Local Presidio Test

A developer tested how HoverBot masks personal data in visitor messages before the reply model sees them, using synthetic inputs on November 2. Presidio replaced a sample email address and a test card number with labels, while the surrounding question stayed intact. The approach runs detection in a self-hosted deployment before any external model call, but it only protects the entity types and confidence thresholds chosen. In six probes, a phone-shaped string was missed even though phone numbers were among the selected types, and names, addresses and order numbers were deliberately left unmasked. The author stresses these are too few samples to measure protection rates, and that masking a request does not erase data stored in the application's own records.
