Why we cannot wait for better post-quantum signature algorithms – ML-DSA now
NIST has nine new post-quantum signature candidates in the pipeline, but Cloudflare’s analysis concludes none are ready to deploy at scale today – ML-DSA (FIPS 204) is the only standardized option with real implementation maturity. If you’re planning post-quantum rollout timelines around those candidates, this changes the calculus: you’re likely deploying ML-DSA first whether you want to or not, and your TLS termination and signing infrastructure needs to account for ML-DSA’s larger signature sizes now.
What to do: Audit your TLS and code-signing stack for ML-DSA readiness this quarter; don’t hold the roadmap for NIST candidate finalization.
- EPIPE on write might mean you’re doing it wrong — Rachel by the Bay · Jul 10
Rachel digs into Apache + php-fpm pipe blockage – the kind of subtle Unix I/O problem where EPIPE is a symptom pointing at a broken assumption about backpressure, not the root cause. Required reading if you’re running fastcgi stacks and seeing intermittent hangs under load. - Rust 1.97.0 released: new symbol mangling by default, Cargo deny-warnings, linker output restored — Rust Blog · Jul 9
Rust 1.97.0 ships with three notable changes: the v0 symbol mangling scheme – introduced in 1.59 and on nightly since November 2025 – is now the default on stable, with the legacy Itanium-based scheme restricted to nightly and slated for removal. Cargo gets a first-class warnings control via CARGO_BUILD_WARNINGS, accepting allow, warn (default), or deny; using it doesn’t bust the build cache, so you can temporarily silence warnings mid-refactor without a full rebuild. Linker output is no longer suppressed on successful links – it surfaces as a linker_messages warning lint, which is intentionally excluded from the standard warnings group since linker output varies by platform. The stabilized API batch adds integer bit-isolation helpers (isolate_highest_one, isolate_lowest_one, highest_one, lowest_one, bit_width) for both primitive integers and NonZero variants. - Graviton5 CPU benchmarks: 30% geomean improvement over Graviton4 — Phoronix · Jul 9
Phoronix benchmarked AWS Graviton5 (M9g) against Graviton4 (M8g) at the 16-vCPU / 64 GB 4xlarge size on Ubuntu 26.04 with Linux 7.0, finding a ~30% geomean improvement across the test suite – roughly matching AWS’s own marketing claims of 25-35% depending on workload type. Graviton5 moves from Neoverse-V2 to Neoverse-V3 (Armv9.2-A) cores, bumps the clock from 2.8 GHz to 3.3 GHz, scales to 192 cores, and upgrades memory from DDR5-5600 to DDR5-8800. The on-demand price premium is about 9% (from $0.718/hr to $0.783/hr in Ohio at 4xlarge), so the performance-per-dollar case is reasonably solid if the 30% figure holds for your actual workload. Graviton5 vs. AMD EPYC and Intel Xeon comparisons are coming in a follow-up, contingent on reader interest covering the cloud costs – worth watching before committing to a migration. - Navigating the ingress-NGINX retirement — CNCF Blog · Jul 9
The community-maintained ingress-nginx controller reached end of life in March 2026 – the Kubernetes Ingress API itself is not going away, just this specific controller. Teams now face two paths: swap in a drop-in replacement like Contour (keeping existing Ingress YAML but manually rewriting all nginx.ingress.kubernetes.io/* annotations), or migrate to Gateway API, which is the upstream-backed successor with role-oriented design, native traffic splitting, and cross-namespace routing. The CNCF post recommends Contour as a stopgap if engineering time is tight, since the Ingress API is feature-frozen and Gateway API requires a fuller refactor. The ingress2gateway tool can automate some translation work, and a parallel rollout – non-critical workloads first – reduces blast radius either way. If you’re already planning platform modernization, Gateway API is the long-term move; if you just need to stop the bleeding, swap the controller class and budget time to finish the job properly. - Bun’s Rust rewrite with AI: 11 days, $165K in tokens, ~1 engineer-year of work — Pragmatic Engineer · Jul 9
Bun’s creator Jarred Sumner used Anthropic’s Fable tool to rewrite Bun from Zig to Rust in 11 days, a migration Sumner estimates would have taken a small team 1-2 years by hand – at a token cost of $165K. The key caveat: Bun has extensive test coverage, which is what made an AI-assisted rewrite viable rather than reckless. The article also covers the broader coding-LLM competitive landscape (GPT-5.6 Sol, Grok 4.5 via Cursor, Meta’s Muse), plus a recurring hiring problem where North Korean developers are using AI filters to pass remote interviews at Western companies. If you’re weighing AI-assisted migration for a large codebase, the Bun case is the clearest real-world data point yet – but the test suite is the prerequisite, not the AI.
