Capturing Innovations and Underlying Physics in Sports / Jung, Chang Kee (speaker) (SUNY Distinguished Professor, Stony Brook University)
Sports occupies an important part of our lives. It is often difficult to flip through the TV channels without encountering sports shows. Surprisingly, large fraction of the intriguing and often spectacular sports actions and feats can be explained using relatively basic physics concepts. In this talk I will present and discuss the physics behind some remarkably creative innovations in popular sports (baseball, soccer/football, volleyball, basketball, high Jump, gymnastics and swimming) using basic concepts in classical physics. The talk will feature exquisite and exclusive videos created by the New York Times graphics/multimedia team for sports that capture innovative feats of athletes like Simone Biles, Derek Drouin and Ryan Lochte. The main part of this presentation was initially created in collaboration with Bedel Saget, a New York Times graphics/multimedia editor for sports. [...]

Romuald Thion - PostgreSQL at the university : some lessons learned / Romuald Thion, (speaker)
The computer science department of Université Claude Bernard Lyon 1 (France) has progressively introduced PostgreSQL in its courses since 2018. Now, more than 400 students enrolled from second to fifth year use PostgreSQL in databases, web, security or system administration courses. In this talk, we will briefly showcase our platform and give feedback on some common pitfalls students and teachers fall into. From our experience, we will propose some directions to promote PostgreSQL to students and teachers..

Anastasia Lubennikova - Advanced PostgreSQL Backup and Recovery methods / Anastasia Lubennikova, (speaker)
As database size and complexity grow, DBAs may face the fact that the functionality offered by built-in tools such as pg_dump and pg_basebackup is insufficient, and more flexibility is required to create reliable backups and manage them. This talk cover various advanced topics in the area of backups: - incremental backups; - archive management; - backup validation; - retention policies; etc. Based on these features, we'll compare various backup/recovery solutions for PostgreSQL. This information will help you to choose the most appropriate tool for your system. Anastasia Lubennikova received her B.S. degree in Applied Mathematics and Information Science from NRNU MEPhI. She has 5 years of experience as a system software developer and speaker. [...]

Gülçin Yıldırım - Evolution of Fault Tolerance in PostgreSQL / Gülçin Yıldırım, (speaker)
PostgreSQL is an awesome project and it evolves at an amazing rate. The talk will focus on the evolution of fault tolerance capabilities in PostgreSQL throughout its versions. The talk will cover the topics listed below: • Robustness of PostgreSQL • PostgreSQL Fault Tolerance: WAL • Transaction? Commit? Checkpoint? • Replication Methods for PostgreSQL • Physical Replication • Standby Modes • Streaming Replication and WAL • Failover and Switchover • Synchronous Commit • Managing Timeline Issues: pg_rewind • Trigger-based Replication • Logical Decoding There are several ways of how to look at fault tolerance [...]

PHYSTAT Seminar: Accelerating Bayesian Computation: Parallelizing Markov Chain Monte Carlo / Caldwell, Allen (speaker) (Max-Planck-Institut fur Physik (DE))
A full-fledged Bayesian computation requries evaluation of the posterior probability density in the complete parameter space.  This can become very time consuming using commonly used algorithms such as Markov Chain Monte Carlos [...]

Microsoft DFS to CERNBox Home Directories migration / Smyrnakis, Apostolos (speaker) (CERN)
More and more people tend to work using different devices, sometimes remotely and/or under different operating systems. Also, everyday collaboration is becoming more and more needed across colleagues. CERNBox, the CERN’s cloud storage system can offer an easy and secure way to share files with colleagues, collaborate and backup your data in the (CERN) cloud while synchronizing your profile across all your devices. As the selected alternative for Microsoft DFS, CERNBox will host users’ personal profile providing them with more quota and making available to them the CERN cloud ecosystem.   For more information on this subject please read the CERN Bulletin article: “Change concerning Windows users: Home Directories will be transferred to CERNBox”
