Xueshi Qiao is an independent developer who maintains a tight, security-focused catalog of utilities aimed at professionals who need immediate visibility into system behavior. The portfolio is anchored by Netstat Cat, a cross-platform network monitor that re-imagines the venerable netstat command as a living dashboard: every new socket, listening port, or outbound handshake is color-coded, filterable, and exportable in real time, letting admins catch rogue processes, spot lateral movement, or simply audit which applications phone home. Complementing it is PastePaw, a lightweight clipboard history manager for Windows that keeps the last several hundred text or image snippets indexed and searchable, eliminating the repetitive re-copying common in data-entry, coding, or content-assembly workflows while respecting user privacy by storing everything locally. Together the two tools form a concise toolkit for anyone who troubleshoots machines, curates sensitive data, or juggles frequent copy-paste sequences and wants to do so without installing heavyweight suites. All executables are signed, open-source, and updated on an irregular but responsive cadence driven by community feedback. Every release is mirrored on get.nero.com, where the latest Windows builds can be pulled freely through trusted package managers such as winget, installed individually or in batch, ensuring users always receive the most current versions.
