• Manu Orsini describes Kyutai’s smaller Pocket TTS models: an 18.2M-parameter version retains the earlier model’s quality, while a 1.9M version trades some naturalness for size and speed through staged pruning and distillation. Kyutai

• Michael Larabel reports a Linux Foundation estimate that a quarter of incoming open-source pull requests are low-quality AI contributions, alongside reported productivity gains and lower entry barriers. Phoronix

• Linux 7.4’s proposed Rust updates include a large Zerocopy refresh, new memory and rate-limiting modules, and better support for self-references and diagnostics. Phoronix

• Nicolas Mattia shows how macOS’s Secure Enclave can hold a non-extractable SSH identity and use Touch ID to approve signatures, with the identity tied to that Mac’s lifetime. Guide

• Konstantin Kakaes reports that number theorists have unpacked an AI-produced quasi-Riemann proof as a synthesis of existing techniques; the full Riemann hypothesis remains open. Quanta

• Tails of the unexpected: Anil Madhavapeddy describes using live OCaml examples in lectures, a student’s question about empty-list tails, and Simon Peyton Jones’s preference for pattern matching over a partial tail function.

• DeepSeek inference deployment: Latent.Space’s translation of DeepSeek’s account describes separate prefill and decode pools, distributed KV-cache storage and request routing that balances compute cost with cached context.

• eMudhra incident report: Mozilla reports independently recovering eight intermediate-CA private keys after a researcher supplied signed proofs, confirming a trivial flaw in key generation.

Conversations on X

• Thorsten Ball presents rapid responses to user feedback as a route to perceived hackability; the Amp clip he reposts argues that large, delayed reviews can create risk. David Cramer stresses enforceable controls and says his team has no substitute yet for peer review of changes that affect customer data. The emphasis differs between short feedback cycles and demonstrating how controls are actually enforced.

• Manish speculates about intent behind eMudhra’s weak keys. Sidu Ponnappa’s repost relays David Crawshaw’s invocation of Hanlon’s razor; other reposts carry the incident report and remediation advice. Those reactions offer interpretations, not evidence of an attacker’s intent.
