1. Tony Hoare has died
Total comment counts : 58
Summary
Jim Miles, a Cambridge acquaintance, pays tribute to Tony Hoare (died at 92), famed for much beyond quicksort (ALGOL, Hoare logic, etc.). He recalls Hoare’s precise memory, warmth, and a career spanning classics to CS, including Russian linguistics and early computer demonstrations. Miles recounts Hoare’s quicksort wager—he bet a faster method existed, quicksort won, and the wager was paid. Despite the bet, Hoare remained professional, often implementing the slower algorithm first when appropriate.

- Overall sentiment: Mixed.
2. RISC-V Is Sloooow
Total comment counts : 9
Summary
Marcin Juszkiewicz (aka hrw) describes 3 months working on Fedora Linux RISC-V port. He triaged Fedora RISC-V tracker entries, submitted ~86 PRs across packages from llvm15 to iyfct, many merged and built for Fedora 43. Build times are slow due to hardware: RISC-V builders have 4–8 cores and 8–32 GB RAM, with LTO disabled to save memory. Emulation with QEMU helps; e.g., 80 cores yields ~4h for llvm15, while Banana Pi takes ~10.5h. They seek faster hardware and may assign heavy packages to them; Fedora 44 planned, keep kernel images consistent, LTO off. Feedback welcome on Mastodon. Red Hat employee.
Overall Comments Summary
- Main point: The thread centers on slow RISC-V progress blamed on silicon implementations (e.g., SOPHGO issues) and build/optimization challenges, with cross-compilation and tooling improvements proposed as remedies.
- Concern: The main worry is that hardware sanctions, fragmented silicon, and lack of architecture-specific optimizations will continue to slow RISC-V development and performance gains.
- Perspectives: The discussion presents a range of views—from blaming silicon and software optimizations for poor performance, to advocating cross-compilation and build accelerators, to recalling ARM’s history and debating compiler choices—showing a mix of skepticism and cautious optimism.

5. After outages, Amazon to make senior engineers sign off on AI-assisted changes
Total comment counts : 45
Summary
Amazon’s AWS and ecommerce divisions have faced outages tied to AI coding tools. A briefing cites a trend of Gen‑AI–assisted changes with insufficient safeguards, prompting a “deep dive” with engineers. An ecommerce outage lasting nearly six hours this month followed a faulty code deployment. AWS also reported at least two AI‑assisted incidents: a 13‑hour December cost‑calculator outage after Kiro AI deleted and recreated an environment, and a second incident not affecting customer‑facing services. Amazon plans stricter governance, requiring senior sign‑off on AI changes; causation of layoffs is disputed.
Overall Comments Summary
- Main point: The thread centers on AI-assisted coding and a policy requiring senior sign-off for AI-generated changes, sparking debate about its impact on productivity, learning, and accountability in large tech teams.
- Concern: The main worry is that mandating senior review will bottleneck development, hinder junior engineers’ learning, and make it harder to trace why decisions were made, risking reliability and outages.
