# Tech & AI Weekly — Major Updates in Open Source, AI Models, Storage Reliability, and Privacy
---
## Highlights Overview
- **Pebble** has open‑sourced core software, mobile apps, and toolchains; multi‑source Appstore with Archive.org backups ensures longevity. Pebble Time 2 ships 2026.
- **Anthropic** releases **Claude Opus 4.5**, improving coding, reasoning, and long‑task execution, with lower prices and better agent/tool integration.
- **Unpowered SSDs** lose data as NAND cells discharge (QLC ≈ 1 yr, TLC ≈ 3 yrs) — unreliable for long‑term cold storage; use 3‑2‑1 backup strategy.
- New **Claude tool features** — on‑demand search/lazy‑load, programmatic invocation, and usage samples — boost multi‑tool efficiency.
- In **France**, GrapheneOS devs refusing backdoors face arrest/server seizure threats, raising privacy and sovereignty concerns.
- **Hacker News Simulator** uses LLM to produce exaggerated satirical posts/comments mimicking HN tone.
- **DDR5 shortage** — 64 GB kit at $600, more than a PS5; supply tight until 2026 due to AI data center demand.
- **Brain organoid research** finds preconfigured electrical activity before birth — innate blueprint for world understanding.
- **Kagi Orion 1.0** macOS browser launches with privacy‑first WebKit core, zero telemetry, and strong content blocking.
- **Karpathy on AI & education** — assume homework may use AI; move critical assessments into supervised classrooms.

**HN:** [Discussion](https://news.ycombinator.com/item?id=46038099) — 717 points | 288 comments
### Summary
- **Risk window:** QLC ≈ 1 yr, TLC ≈ 3 yrs, MLC ≈ 5 yrs, SLC ≈ 10 yrs — in high temp/heavy use.
- **Advice:** Follow **3‑2‑1 backup rule** — 3 copies, 2 media types, 1 offsite/offline.
- **ECC/Parity use** — extend retention & recovery capability.
- Long‑term cold storage better served by other media (tape, optical).
