Cursor Uses S3 WAL to Scale Git Storage to More than 300 Pushes per Second

Leela Kumili — Wed, 30 Sep 2026 13:47:00 GMT

Cursor has introduced Continuity, a Git storage architecture that uses an S3 backed write ahead log as the source of truth. The design turns local NVMe repositories into warm caches and separates replica coordination from consistency. Cursor reports linear read scaling with up to 100 replicas and more than 300 pushes per second with S3 Express One Zone in synthetic tests.

Agents Refactor 300K Lines in Three Weeks, and Practitioners Ask What It Proves

Steef-Jan Wiggers — Wed, 30 Sep 2026 06:16:00 GMT

CodeScene has published a case study in which coding agents refactored 300,000 lines of C over three weeks for roughly $4,000 in tokens, verified by a frame-by-frame replay harness. The agents built a playbook of codebase-specific recipes along the way. Practitioners have questioned the scope, the metric, and how much of the result depends on the harness.

Artifactory Vulnerabilities under Active Exploitation Enable Authentication Bypass and Admin Access

Sergio De Simone — Mon, 28 Sep 2026 19:00:00 GMT

Three Artifactory vulnerabilities under active exploitation enable authentication bypassing on Internet-accessible, self-hosted deployments, potentially allowing attackers to establish persistent administrator access in under five minutes. The exploits then enable dangerous activity, including credential and key theft, arbitrary code execution, persistence, and anti-forensics measures.
