EarthCARE lifts the clouds on climate modelshttps://www.esa.int/Applications/Observing_the_Earth/FutureEO/EarthCARE/EarthCARE_lifts_the_clouds_on_climate_modelsTrue to its promise, the European Space Agency’s EarthCARE satellite is now being used to calculate directly how clouds and aerosols influence Earth’s energy balance – the all-important balance that regulates our climate. In doing so, EarthCARE is poised to sharpen the accuracy of climate models, the very tools that guide global climate policy and action.

Scientists trace ancient mega watersheds on Marshttps://www.marsdaily.com/reports/Scientists_trace_ancient_mega_watersheds_on_Mars_999.htmlLos Angeles CA (SPX) Dec 03, 2025 Billions of years ago, rainfall on Mars fed rivers that cut valleys, overtopped crater rims and carved canyons, with some flows likely reaching a northern ocean basin on the planet. Researchers at The University of Texas at Austin have now organized these fluvial features into large drainage systems, producing the first global inventory of major Martian river basins and identifying 16 larg

ClipE96: We Left the Clipboard Unguarded for 40 Yearshttps://news.ycombinator.com/item?id=46051434In 1984, Apple shipped copy and paste. It was a miracle of usability—and architecturally broken from day one.Press Ctrl+C and the entire payload—bytes, formatting, metadata, embedded objects—dumps into a system buffer that any application can read. No auth. No logging. No revocation.The clipboard is a broadcast channel disguised as a convenience.The catastrophe: The clipboard is now the #1 data exfiltration vector in enterprise. 77% of knowledge workers paste corporate data into AI tools. Every paste bypasses your CASB, EDR, SIEM, and DLP. Your security stack guards the front door while users walk data out the side.The waste: 40 billion copy operations/day × ~100KB average = 4 exabytes of daily churn. RAM pressure, cloud sync, VM duplication—all unnecessary. Annualized: 83B kWh, 33M tons CO₂, $10B in energy costs. We're burning a small nation's power grid because nobody questioned whether copying a sentence needed to ship a document.The semantic lie: Copy and cut were always opposites,

Show HN: Fixing a single pointer bug unlocked 1M+ row JSON parsing on Windowshttps://news.ycombinator.com/item?id=45979409I've been building a cross-platform JSONL viewer app that handles multi-GB files. It worked perfectly on macOS (my development machine), but consistently crashed on Windows at exactly 2,650 KB. Here's the debugging journey and the tiny fix that made all the difference.The Problem- macOS: Handles 5GB+ files effortlessly - Windows: Crashes at 2,650 KB every time - Same codebase, cross-compiled from Mac Silicon to Windows using MinGWThe InvestigationAdded detailed logging to track execution. The crash happened during string interning after successfully parsing ~6,000 rows. Not during parsing, not during file I/O, but during the merge phase.The Root CauseMy StringPool class used std::unordered_map to deduplicate strings. The string_views pointed into a std::vector.When the vector grew and reallocated, all the string_view keys became dangling pointers. The hash map was full of invalid references.Why did it work on macOS? Different memory allocator behavior, different default stack sizes (8M
