- 1eMudhra certificate authority keys cracked in milliseconds●Eight Bits of Trust: eMudhra's CA keys cracked in milliseconds
Security researchers report that certificate authority keys issued by Indian digital trust firm eMudhra could be cracked in milliseconds, with the flaw likened to just eight bits of effective security. The finding raises questions about how widely eMudhra certificates are trusted and has prompted discussion among security engineers about key generation practices and the audit standards governing certificate authorities.
- 2Developers grapple with shipping AI code they don't understand●Ask HN: How to deal with shipping AI-written code you don't understand?
A discussion is underway among developers about the risks of deploying AI-generated code that engineers do not fully understand. The question, raised on Hacker News, asks how teams should handle responsibility, debugging, and maintenance when code is largely written by AI tools. Commenters are debating whether such code can be safely reviewed, who is accountable when it fails, and whether this is becoming a normal part of software engineering practice.

Engineer James Calabro has published a write-up introducing One Hash Bloom Filters, a variant of the classic Bloom filter data structure that uses a single hash function instead of several. The piece walks through the design trade-offs, trading some accuracy for simplicity and speed. Developers on Hacker News are debating the practical value of the approach and comparing it with standard Bloom filter implementations.

Practical Engineering has published a piece examining why fire escapes, once a fixture of urban buildings, have largely vanished from modern architecture. The article traces how building codes moved toward enclosed stairwells, sprinkler systems and other interior safety measures, making exterior iron stairs a relic of older city blocks. Readers are discussing the history and safety trade-offs of these iconic structures.
