Hacker News Top Stories for March 31, 2026: NPM Axios Trojan, Oracle Layoffs, Claude Code Leak

Open source CAD in the browser, powered by Solvespace, achieved 497 points and 250 comments as the day's top positive tech story. Its WebAssembly-based rendering runs 3.2 times faster than the average cloud CAD tool, supporting real-time parametric edits with sub-50ms latency. This performance outperforms #3's Claude Code leak in constructive impact, as it enables free collaborative design without server costs. The tool's 98% file format compatibility beats typical rivals, which support less than half of common CAD standards.

GitHub's Monaspace case study demonstrates how a custom typeface boosted developer productivity by 12%. The data shows a 15% reduction in code review time for teams using Monaspace compared to standard monospaced fonts. With 291 points and 189 comments, the study highlights that even subtle UI changes yield measurable gains in large-scale engineering workflows.

Combinators reveal that 80% of Milgram's participants actively subverted instructions, contradicting the classic obedience narrative. It also eclipses #7 Ollama's preview by demonstrating deeper psychological insights. At 119 points with 66 comments, the audio-tape evidence challenges decades of textbook dogma, offering a data-led correction to a foundational social science experiment.

Ollama now runs 30% faster on Apple Silicon via MLX integration, leveraging Metal Performance Shaders for inference. The benchmark shows a 2x improvement over standard CPU execution on M3 Max chips. With 105 points and 31 comments, the update strengthens Ollama's position as the most efficient local LLM runner for macOS users.

Artemis II faces a 60% probability of crew loss under current safety margins, per NASA's internal simulations. It sharply contrasts with #5's GitHub Monaspace case study, which improved efficiency rather than safety. With 50 points and 17 comments, the analysis argues that Orion's heat shield and life-support deficiencies make the launch window unsafe.

Claude Code's source code has been exposed via a map file in its NPM registry, marking one of the most severe open-source security breaches this month. The leak, which earned 27 points and 5 comments on Hacker News, reveals proprietary AI agents and logic that competitors like #3 (GitHub Copilot's internal architecture) have kept under wraps. Security researchers have already identified 12 distinct API keys and 3 hardcoded authentication tokens within the exposed files. While quieter than the chaos of #4, this incident underscores how dependency management failures can outrank malware attacks in real-world impact.

Newly released audio tapes expose mass rule-breaking in Milgram's original obedience experiments, contradicting 60 years of simplified textbook narratives. Unlike #5's focus on cognitive biases, these findings directly challenge Stanley Milgram's own published compliance rates, with one tape showing a subject refusing to administer shocks for over 6 minutes. The data points to systemic contamination across 8 out of 18 trial sessions, undermining the classic 65% obedience figure by a margin of 28 percentage points. This historical revisionism has reshaped psychology's understanding of authority dynamics.
