Quantum hardware hits fault-tolerance thresholds; prioritize post-quantum crypto now
Around the web • December 21, 2025
Multiple platforms now demonstrate >99.9% two‑qubit gate fidelities—at or above fault‑tolerance thresholds—making late‑decade roadmaps more credible. The practical takeaway for engineering leaders: begin post‑quantum cryptography migrations before timelines go opaque, separating real progress from hype.

OpenAI releases chain-of-thought monitorability suite, quantifies compute tradeoffs
Around the web •December 19, 2025
OpenAI proposes a framework and 13 evaluations (24 environments) to measure how monitorable a model’s chain-of-thought is. Findings: more test‑time reasoning can boost monitorability with a small “tax,” larger pretraining may move cognition into activations (harder to observe), and post‑hoc follow‑ups can elicit deeper reasoning—positioning CoT monitoring as complementary to mechanistic interpretability for scalable control.
Run Local Coding LLMs: Setup, Quantization, and Cost Tradeoffs
Around the web •December 21, 2025
A practical guide to running local coding LLMs that can cover most day‑to‑day dev work at lower cost. It details RAM math for weights/KV cache, recommends larger models with heavier weight quantization but lighter KV cache quantization, compares MLX vs. Ollama, and provides step‑by‑step setup and model picks for 8–128GB machines—calling out reliability gaps and ROI implications.

Find Real Customer Pain: Backlog Launches Public, Verified Problem Repository
Around the web •December 21, 2025
Backlog aggregates recurring work problems posted by domain experts and validated by peers, giving builders a vetted queue of demand. Developers can request access to detailed context and co‑create solutions—reducing solution‑in‑search‑of‑a‑problem risk and improving odds of product–market fit across industries like manufacturing and healthcare.
Measure Feature Impact With TARS: Target, Adoption, Retention, Satisfaction
Smashing Magazine •December 19, 2025
TARS is a lightweight framework to evaluate features with four inputs—Target audience, Adoption, Retention, and Satisfaction—plus an S÷T score and a 2×2 to spot core, overperforming, or liability features. It emphasizes leading indicators over conversion to guide PM/Design/Eng toward discoverability and quality improvements.
