Gamma system

Alessandro Orso, Donglin Liang, Mary Jean Harrold, Richard Lipton
2002 Software engineering notes  
In this paper, we present the Gamma system-a new approach for continuous improvement of software systems after their deployment.  ...  This system enables software producers (1) to perform continuous, minimally intrusive analyses of their software's behavior, and (2) to use the information thus gathered to improve and evolve their software  ...  Bowring, Jim Jones, and Anup Rao provided useful ideas and comments and helped with the implementation of the system.  ...

Open-source Radiative Modelling Tools for Extragalactic VHE gamma-ray Sources [article]

Cosimo Nigro, Andrea Tramacere
2022 arXiv   pre-print
In this review, we discuss various open-source software for modelling the broad-band emission of extragalactic sources from radio up to the highest gamma ray energies.  ...  After considering the currently available software as a first generation of open-source modelling tools, we outline some desirable characteristics for the next generation.  ...  Continuous integration (CI) and continuous deployment (CD) are performed by GitHub Actions. Test suites are performed for each new release, that are available via conda and pip.  ...
