The Residential Proxy Problem: Shared Infrastructure and Rapid Rotation

We analyzed 170+ million residential proxy IPs over a 90-day period (86M IPv4, 87M IPv6) and discovered two patterns that explain why fraud detection is so hard: 46% of residential proxy IPs appear across multiple provider networks simultaneously (70% for IPv4, 22% for IPv6). The same compromised infrastructure, infected routers, malware-laden devices, bandwidth-sharing apps, is accessible … Read more

People, Process, Context: The Operating Model Modern Defect Resolution Needs

Engineering teams are shipping more code than ever, driven by distributed systems and AI-assisted development. Defect prevention and resolution, however, still operate as manual, reactive work. This creates a structural imbalance: output scales, but reliability and confidence do not. Teams feel constantly busy yet perpetually behind, a signal that the operating model itself is no … Read more

How Seyond Built LiDAR for Every Range: The Tech Behind Physical AI

Shem Albert Photo courtesy of Seyond Machines still struggle to see. Autonomous vehicles miscalculate distances. Delivery robots stumble on curbs. Industrial sensors fail when the weather turns harsh. Seyond addressed this gap by constructing a full spectrum of LiDAR sensors spanning from 0.01 meters to 500 meters, giving robots the visual acuity needed to operate … Read more

Inside Will Jiang’s Ethical Growth Hacking Strategy for Social Media

Long before “engineering” became a formal career path, it was already part of Will Jiang’s daily life. Growing up in China, Jiang was the student teacher whom a classmate turned to when a laptop froze minutes before class. By high school, he was maintaining his school’s network infrastructure by diagnosing connectivity issues, keeping systems online, … Read more

Building ML-Ready Data Platforms on Cloud: Turning Experiments into Systems

Machine learning models often perform well during experimentation. Offline metrics improve, prototypes demonstrate potential, and early validation builds confidence across teams. In controlled environments, systems behave predictably and progress feels steady. The transition to production introduces a different set of pressures. Training jobs fail intermittently. Features arrive outside expected time windows. Historical data changes without … Read more
