A developer built a small recurrent neural network paired with an external memory system to test whether learned experience could survive a complete substrate reset. The experiment used a fixed cue-response task where the network had to map specific inputs to correct actions, with chance performance at 33%. Results showed that external memory alone achieved near-perfect accuracy, while plasticity alone underperformed at roughly 47%, and combining both yielded 88%. Crucially, the memory system was constrained to only bias internal network states rather than directly select actions, preserving the integrity of the test. The key finding was that externally stored experience could reinstate correct behavior in a reset network that had never independently learned the task.
Security researcher Micah Lee has uncovered multiple vulnerabilities in Flock Safety's license plate recognition cameras, including hardcoded credentials embedded in the devices. These flaws could potentially allow unauthorized actors to gain access to the cameras or the data they collect. Flock Safety cameras are widely deployed by law enforcement agencies across the United States to monitor vehicle movements. The findings raise significant privacy and security concerns given the sensitive nature of the surveillance data these devices capture and store.
A software developer's routine installation of ffmpeg on a Linux machine prompted a deeper look at what package installation actually involves. Running apt install does far more than add a binary — it executes maintainer-written scripts as root, updates system databases, rewrites symlinks, drops config files into /etc, and triggers changes across dependencies. None of this process is sandboxed, meaning the user implicitly trusts the package maintainer and every upstream dependency with full system access. The author notes the greater risk lies not in obviously malicious packages but in routine, trusted ones that no longer attract scrutiny. The piece urges users and AI agents alike to treat any install command as a deliberate grant of root authority, not a harmless default action.
A critical remote code execution vulnerability, tracked as CVE-2026-16723, has been disclosed in Fastjson versions 1.2.68 through 1.2.83, scoring as high as 9.8 on the CVSS scale. The flaw requires no authentication and exploits a trusted code path in the @JSONType annotation-handling branch, bypassing both AutoType and safeMode protections entirely. An attacker can host a malicious JAR file over plain HTTP and trigger execution simply by sending a crafted JSON payload to any endpoint calling JSON.parseObject(). Unlike previous Fastjson vulnerabilities, this exploit does not rely on known gadget classes or blacklisted type names, making existing defenses ineffective. Alibaba has declared Fastjson 1.x end-of-life and will not issue a patch, directing users to migrate to Fastjson2.
