Blindstore, a Private Information Retrieval database10m
Blindstore is a database that ensures confidentiality of information retrieval. I'll cover what Private Information Retrieval is, how it is different from current privacy schemes and how the magic happens.

Towards the 2nd Generation Accelerator Transient Data Analysis Framework10m
During the last two years, CERNs Large Hadron Collider (LHC) and most of its equipment systems were upgraded to collide particles at an energy level twice higher compared to previous operational limits. System upgrades and the increased machine energy pose new challenges for the analysis of transient data recordings, which have to be both dependable and fast. With the LHC having operated for many years already, statistical and trend analysis across the collected data sets is a growing requirement, highlighting several constraints and limitations imposed by the current software and data storage ecosystem. Based on several analysis use-cases, this paper highlights the most important aspects and ideas towards an improved, 2nd generation data analysis framework to serve a large variety of equipment experts and operation crews in their daily work.

Achieving dependable software through Continuous Delivery and Quality Monitoring10m
During the short presentation i would like to highlight the importance of Continuous Delivery processes which facilitate software development. As i have only 5-10 minutes, it will have a form of a simple story from software developer life. Official abstract for "1st developers @ CERN": The TE-MPE-MS Software team is a small group of people responsible for developing software for machine protection. Main projects include mostly software for the equipment supervision and testing. The usage of the Scrum methodology involves getting clients’ feedback as soon as possible which pushed the requirement to integrate all the time and deliver software in small chunks. To meet these requirements the team successfully implemented Continuous Integration and Delivery processes using multiple open source and proprietary products including: Gradle, Flyway, JUnit+Mockito, SonarQube and Bamboo. The idea for the presentation is to present our implementation of the CI/CD paradigms and explain on real live examples advantages and drawbacks of the current solution. During the presentation we will try to cover all the required steps which should automatically triggered by a developer’s commit. The presentation should give users a good hands-on experience on basic CI/CD principles and allow them to design and implement simple software delivery platform.

Density-based Outlier Detection10m
Often we have a dataset where most of the data is produced by a known mechanism (or several mechanisms) which we understand, but some data is produced by a different process. In such cases we can consider the known processes as background to detect the signal. However, what about the case where we do not have knowledge about the underlying processes, but want to detect which part of our dataset is unusual or anomalous? One method that can be used in this case is density-based outlier detection, where each data point is considered in relation to its local neighbourhood.

Applications of Timepix detectors10m
Timepix is a hybrid pixel semiconductor detector of the Medipix family, derived from the pixel detector developments at CERN and originally designed for X-ray imaging. This presentation makes an illustrative look at the current applications of these detector from medicine to outer space, and back to particle physics' experiments.

A proposal for a C++ framework for writing highly-readable code with automatic multi-level paralelism10m
Using C++ template metaprogramming and assumptions about typical workloads in plasma physics computing, a framework if proposed to facilitate writing massively parallel programs in C++ in such a way, that the code written by the user closely resembles wahtever would be seen in a paper, while the framework effectively hides the implementation details of the parallelization structures. The ideas are demonstraed on a proof-of-concept Particle-in-Cell code used for simulations of interactions of hig power ultrashort laser pulses with plasmas.

From Community Detection to Emergence10m
We are going to have a small trip through the simple ideas of finding patterns in graphs, what a community means, define complex systems and then wonder ourselves on what emergence means for us.
