wFabricSecurity adds token-bucket rate limiting to protect Hyperledger Fabric endorsement nodes

·1 views

The open-source wFabricSecurity library has introduced token-bucket rate limiting to safeguard Hyperledger Fabric endorsement peers from denial-of-service-style attacks. Without such controls, a looping worker flooding peers with thousands of signature requests can exhaust CPU resources, since ECDSA signature verification is computationally expensive. The new RateLimiter component enforces per-participant quotas based on Common Name or IP address, rejecting abusive request spikes before cryptographic processing begins. A RateLimitError exception is raised when a participant exceeds their token allowance, allowing legitimate traffic to continue uninterrupted. The library is compatible with Python 3.10 and above and is available on both GitHub and PyPI.

Claude AI Agent Autonomously Fixes Bugs, Pushes Code, and Files Merge Requests Overnight

A development team used a scheduled Claude Code agent to automatically process seven bugs from a 34-item backlog overnight, with three fixes merged before the next workday's lunch. The agent operates in a fully autonomous loop, reading task boards via API, writing targeted code fixes, running tests, pushing branches, and creating merge requests on GitLab. The system integrates with a project management tool called FlowBoard, pulling structured bug context such as reproduction steps, error logs, and environment details to guide the AI's fixes. Anthropic has documented Claude Code's ability to navigate codebases, run tests, and produce working patches when given well-structured input. Developers caution that fix quality depends heavily on the quality of the bug report, making structured ticket data a prerequisite for reliable automated output.

AI Project Management Tools in 2026 Now Track Both Developers and AI Agents

The role of project management tools is evolving as AI agents like Claude Code and Codex increasingly handle development tasks alongside human engineers. Traditional tools built around tracking deadlines and assignments are no longer sufficient when AI agents are also executing work within the same workflow. Modern AI project management platforms are now expected to offer capabilities such as turning rough requirements into tasks, integrating with developer environments, and allowing AI agents to receive, execute, and report on work. Tools like Sharkly are designed specifically as shared work systems where humans and AI agents collaborate within a unified coordination layer. Key features in this new generation of tools include parallel agent task execution, shared project context, human review workflows, and integration with existing development infrastructure.

Developer builds tic-tac-toe agent using real fruit fly brain wiring data

A software developer has created FlyCNS-TicTacToe, a project that uses publicly available fruit fly connectome data to simulate neural decision-making in a game of tic-tac-toe. The fruit fly connectome is a complete map of the insect's nervous system, detailing every neuron and its connections, which the developer accessed via the neuPrint database. Real synapse counts and predicted neurotransmitter types from the dataset were used to route game-board signals through a subset of the fly's central brain neurons. Because the biological circuit lacks strategic look-ahead, a minimax algorithm guides move selection while the fly circuit is used to break ties among equally strong options. The project is open-source under an MIT licence, with connectome data credited under CC-BY, and the code is available on GitHub.
