**Top 5 Stories (ranked by AI/Startup relevance)**

**#1. Launch HN: Freestyle: Sandboxes for AI Coding Agents** — Score: 10/10
Freestyle is a YC-backed San Francisco startup offering unified sandbox infrastructure — fast VMs, Git, and deployment — purpose-built for AI coding agents like Devin and Cursor. VMs spin up in under 700ms with live forking and pause/resume to cut idle costs. It directly addresses the messy execution environment problem that every team building agentic coding products hits.

**#2. A Cryptography Engineer's Perspective on Quantum Computing Timelines** — Score: 6/10
Cryptographer Filippo Valsorda argues that cryptographically-relevant quantum computers could arrive as early as 2029, citing Google research showing elliptic curve attacks require far fewer qubits than previously thought and Oratomic results suggesting 10,000 physical qubits may suffice. He calls the delay risk "unacceptable" and urges immediate migration to post-quantum standards ML-KEM and ML-DSA. Any startup handling sensitive data or building security tooling needs to treat this as an active planning horizon, not a distant threat.

**#3. I won't download your app. The web version is a-ok** — Score: 5/10
The author makes a sharp case against the industry pattern of deliberately degrading web experiences to funnel users into native apps, arguing that most apps are just thin JSON clients masquerading as necessary installs. The piece dissects the "enshittification loop" where PM incentives reward app-store capture over user experience. A relevant signal for startups: users are increasingly hostile to forced app installs, and web-first strategies retain goodwill.

**#4. Germany Doxes "UNKN," Head of RU Ransomware Gangs REvil, GandCrab** — Score: 2/10
Germany's BKA publicly identified Daniil Shchukin, 31, as the operator behind both GandCrab and REvil — ransomware operations that pioneered double extortion and caused over €35 million in damage across 130+ attacks. The U.S. previously tied ~$317K in crypto to Shchukin, who remains a fugitive in Krasnodar, Russia. A cybersecurity story with operational significance but low direct relevance to AI or startups.

**#5. sc-im Spreadsheets in Your Terminal** — Score: 2/10
sc-im is a vim-keybinding terminal spreadsheet with support for CSV/XLSX/ODS import-export, Lua scripting, GNUPlot integration, and up to 65,536 rows. It's a well-executed open-source tool for developers and sysadmins allergic to GUI applications. No meaningful AI or startup angle — pure developer tooling nostalgia.
