PDF Redaction Failures Exposed: Why Your Sensitive Data Might Be ‘Naked’
1 months ago 高效码农The Illusion of Privacy: Why Your PDF Redactions Might Be Leaving Data “Naked” In an era defined by data transparency and digital accountability, we have a dangerous habit of trusting what we see—or rather, what we can’t see. When you see a heavy black rectangle covering a name or a social security number in a legal document, you assume that information is gone. At Free Law Project, we’ve spent years collecting millions of PDFs, and we’ve discovered a disturbing reality: many redactions are merely digital theater. Instead of permanently removing sensitive data, users often just draw a black box over …

Taming Hyper-Connections: How Geometric Constraints Revolutionize LLM Training Stability
1 months ago 高效码农When Residual Connections Go Rogue: How We Tamed Hyper-Connections with Geometry Hyper-Connections promised better performance but delivered training instability. Manifold-Constrained Hyper-Connections fix this by forcing residual mappings onto the Birkhoff polytope, restoring stability while preserving all performance gains with only 6.7% overhead. Introduction: The Hidden Cost of Wider Residual Streams What happens when you try to increase a model’s capacity by widening its residual connections without adding constraints? You get unpredictable signal explosions that crash training runs. We learned this the hard way while training a 27-billion parameter model. For a decade, residual connections have been the quiet heroes of …
Go vs TypeScript Backend Performance: 2026 Benchmark Verdict
1 months ago 高效码农Go (Golang) vs. TypeScript (Bun): 2026 Performance Benchmark and Backend Strategy Snippet In static performance tests, Bun (TypeScript) reaches a peak of 200,000 RPS, matching Go (Fiber). However, in real-world database scenarios, Go outperforms Bun with 84,000 RPS, significantly lower latency, and superior connection pool management. While Bun immediately occupies all 500 database connections, Go dynamically scales them based on load, proving more stable for complex microservices,. The Evolution of Modern Backend Runtimes The landscape of backend development is currently defined by a tension between developer velocity and raw performance. For many, the greatest appeal of using JavaScript—and more recently, …
