Edge computing processes data near sources for low latency but faces cybersecurity risks in decentralized data aggregation from resource-constrained devices. This paper proposes a blockchain-enabled framework with homomorphic encryption and lightweight validation to ensure confidentiality, integrity, and authenticity. Homomorphic encryption enables computations on encrypted data without decryption, preserving privacy during aggregation. Lightweight validation verifies integrity efficiently, while blockchain provides immutable logging for transparency and tamper resistance. Simulations confirm low overhead in delay, validation, and throughput, with strong defense against forgery, replay attacks, and node compromise. The framework suits smart cities, IoT, and healthcare for secure, resilient data management.
This publication proposes a definition and a classification of agile software development approaches and analyses ten software development methods that can be characterized as being "agile" against the defined criterion.

The study shows that agile practices improve both informal and formal communication, but indicates that, in larger development situations involving multiple external stakeholders, a mismatch of adequate communication mechanisms can sometimes even hinder the communication.

Jennifer Neville did not want to go into computer science—but that’s exactly where she landed. Neville discusses the starts and stops that led to her professional sweet spot and her work identifying “surprising failures” making it hard for AI to handle complexity.
