Open-Source ANSS Quake Monitoring System Software J
Focus Section: Regional Seismic Networks in North America Open-Source ANSS Quake Monitoring System Software J. Renate Hartog*1, Paul A. Friberg2, Victor C. Kress1, Paul Bodin1, and Rayomand Bhadha3 Abstract ANSS stands for the Advanced National Seismic System of the U.S.A., and ANSS Quake Monitoring System (AQMS) is the earthquake management system (EMS) that most of its member regional seismic networks (RSNs) use. AQMS is based on Earthworm, but instead of storing files on disk, it uses a relational database with replication capability to store pick, amplitude, waveform, and event parameters. The replicated database and other features of AQMS make it a fully redundant system. A graphical user interface written in Java, Jiggle, is used to review automatically generated picks and event solutions, relo- cate events, and recalculate magnitudes. Add-on mechanisms to produce various post- earthquake products such as ShakeMaps and focal mechanisms are available as well. It provides a configurable automatic alarming and notification system. The Pacific Northwest Seismic Network, one of the Tier 1 ANSS RSNs, has modified AQMS to be com- patible with a freely available, capable, open-source database system, PostgreSQL, and is running this version successfully in production. The AQMS Software Working Group has moved the software from a subversion repository server hosted at the California Institute Cite this article as Renate Hartog, J., of Technology to a public repository at gitlab.com. The drawback of AQMS as a whole is P. A. Friberg, V. C. Kress, P. Bodin, and that it is complex to fully configure and comprehend. Nevertheless, the fact that it is very R. -

DOI: https://doi.org/10.5334/jors.244 SOFTWARE METAPAPER DataDeps.jl: Repeatable Data Setup for Reproducible Data Science Lyndon White, Roberto Togneri, Wei Liu and Mohammed Bennamoun The University of Western Australia, Crawley, Western Australia, AU Corresponding author: Lyndon White ([email protected]) We present DataDeps.jl: a julia package for the reproducible handling of static datasets to enhance the repeatability of scripts used in the data and computational sciences. It is used to automate the data setup part of running software which accompanies a paper to replicate a result. This step is commonly done manually, which expends time and allows for confusion. This functionality is also useful for other packages which require data to function (e.g. a trained machine learning based model). DataDeps.jl simplifies extending research software by automatically managing the dependencies and makes it easier to run another author’s code, thus enhancing the reproducibility of data science research. Keywords: data management; reproducible science; continuous integration; software practices; dependency management; open source software; JuliaLang 1 Introduction In the movement for reproducible sciences there have These tasks are automatable and therefore should be been two key requests upon authors: 1.

The platform managing application delivery lifecycle is difficult because accommodates a strategy known as Continuous Integration and Continuous Delivery (CI/CD). The phase consists of of those complexities. Dealing with those daunting and several stages, followed by testing of the system and its complex tasks, one solution is using the DevOps [3] [4] deployment. For starters, the CI/CD platform will be deployed approach. for software projects of students in the Faculty of Information The relatively new emerging DevOps is a culture where Technology, Universitas Kristen Maranatha.
