Audio forensics is the field of forensic science relating to the acquisition, analysis, and evaluation of sound recordings. These recordings are normally used as evidence in an official venue. In this blog, we discuss a modern approach to forensic audio analysis, using artificial neural networks, digital signal processing, and big data.

Enterprise Control Language (ECL) Workunit Services standard library functions can be used to capture details about workunits running on Thor including processing time, errors, current state, and more. Capturing these details allows for monitoring, trending, error analysis, degradation, and other data points that can help improve the efficiency of Thor environments.  In this blog, we will look at how to use this information to monitor the system with visualizations in Power BI.

This is the first in a series of blogs about the new development work in progress to provide a Cloud native version of our platform. Our latest release series, HPCC Systems 7.8.x, includes the first wave of changes. In this blog, Richard Chapman talks about our journey to the Cloud and demonstrates how to setup a simple test cluster using a default helm chart.

Massive computation workflows utilize High Performance Computing Cluster (HPCC) Systems environments that require significant resources, but these resources are only needed during processing. A commercial cloud service is a great resource to facilitate a short term need for computing capacity, without a long term commitment. It allows the user to access computing services, such as servers, storage, networking, and software over the internet (“the cloud”). In this blog, we discuss how HPCC Systems was deployed on the Microsoft Azure cloud computing platform to test custom data.

​​​​​​​Sarah Fabius has worked for more than five years at LexisNexis Risk Solutions, where she is a systems engineer and an HPCC Systems ambassador. She has a passion for technology and enjoys finding unique ways to promote diversity and inclusion within the HPCC Systems community. Throughout the year, you can find Sarah leading ECL Code Camps and conferences for women in technology, including the annual She is Tomorrow’s Technologist, a LexisNexis Risk Solutions conference for female students interested in technology. We sat down with Sarah to discuss her experience at LexisNexis Risk Solutions, some of her favorite moments working in the community and advice she would give to young technologists looking to get into the industry.

The HPCC Systems core developers gathered together to discuss future plans for the HPCC Systems platform. These offsite meetings happen twice a year, bringing together a team of developers that usually work remotely from each other in Europe and the USA. While the team meets regularly by conference call, these offsite meetings are the perfect opportunity to brainstorm uninterrupted in person. Lots of ground is covered during this offsite meeting week. Read on to find out more about the future plans for the HPCC Systems platform.

In today’s world, Data Analytics is an important part of sports. Sports organizations on every level use data analytics to predict and improve player performance, a team’s quality of play, prevent injury, increase revenue, and more. Christopher Connelly, a Sport Scientist at North Carolina State University (NCSU), spoke at Community Day 2019 and HPCC Systems Tech Talk 29 about the university’s Athlete 360 program.

How can we make a long-running ECL job complete sooner? Are the assumptions made regarding the datasets correct? What is the ideal size of the cluster that for this job? Post-execution workunit analysis is an important process to answer these questions and gather the information necessary to optimize workunits. Shamser Ahmed introduces the Workunit Analysis Tool, designed for ECL developers to analyse workunit performance which is available from HPCC Systems 7.6.x.

Our annual Community Day Summit is an exciting event, rich in content, providing a wide range of learning and networking opportunities. Community Day is packed with presentations and breakout sessions while the day before, there is the opportunity to attend an ECL workshop and students from across our academic community present their work at our technical poster contest. Come and share our reflections on this event and watch the presentations for the first time or review them at your leisure!
