Cassandra Day London 2015: The Resilience of Apache CassandraDataStax Academy
Speaker(s): Carlos Rolo, Cassandra Consultant at Pythian
Showing how Cassandra resilience can keep your data save even when a multitude of failures happen. This is a description how our team kept a 15 node cluster running (3 nodes per DC, 5 DCs) when a multiple DC fail happen and the cluster was already stretched out resource wise.
Alle Radici della Transumanza - Week end in Abruzzo 11 - 12 Luglio 2015Portante Andrea
Programma di viaggio del week end a Campo Imperatore, Santo Stefano di Sessanio Rocca Calascio Castel del Monte 11 e 12 Luglio 2015, organizzato dal Touring Club.
Arte storia natura e cibo.
Prevista osservazione guidata del fantastico cielo stellato, libero da inquinamento luminoso, insieme all'astronomo Stefano Giovanardi
How health promotion can reduce excess mortality in severe mental disorders, presentation held at WHO expert group meeting in Geneva, Switzerland, 19.11.2015
Cassandra Day London 2015: Building Your First Application in Apache CassandraDataStax Academy
Speaker(s): Luke Tillman, Apache Cassandra Language Evangelist at DataStax
You’ve heard the talks, followed the tutorials, and done the research. You are a font of Cassandra knowledge. Now it’s time to change the world! (Or at least build something to make your boss happy). In this talk we’ll walk through the process of building KillrVideo, an open source video sharing website where users can upload and share videos, rate them, comment on them, and more. By looking at a real application, we’ll talk about architectural decisions, how the application drives the data model, some pro tips when using the DataStax drivers, and some lessons learned from mistakes made along the way. You’ll leave this session ready to start building your next application (world-changing or otherwise) with Cassandra.

R OUND-ROBIN VERIFICATION AND FINAL DEVELOPMENT OF THE IEC 62788-1-5 ENCAPSUL...Claudio Liciotti
Polymeric encapsulation materials may a change size when processed at typical module lamination temperatures. The relief of residual strain, trapped during the manufacture of encapsulation sheet, can affect module performance and reliability. For example, displaced cells and interconnects threaten: cell fracture; broken interconnects (open circuits and ground faults); delamination at interfaces; and void formation. The IEC 62788-1-5 standard quantifies the maximum change in linear dimensions that may occur to allow for process control of size change. Developments incorporated into the Committee Draft (CD) of the standard as well as the assessment of the repeatability and reproducibility of the test method are described here. No pass/fail criteria are given in the standard, rather a repeatable protocol to quantify the change in dimension is provided to aid those working with encapsulation.
Docker on a laptop is easy, but Docker in the cloud is hard. What makes that transition so hard, and what can we do about it? How does this challenge affect the hosting infrastructure and application design? Casey will share lessons learned so far and further questions uncovered in Joyent’s work to build support for Docker in public and private cloud environments.

Cassandra Day London 2015: British Gas Connected Homes: 5 Things We Wish We H...DataStax Academy
Speaker(s): Josep Casals, Lead Data Engineer at British Gas Connected Homes
British Gas Connected Homes (the creators of Hive Active Heating) embarked last year in the creation of a unified platform for all their different IoT projects. The company is a subsidiary of British Gas specialising in connected devices in the home and handles data ranging from smart gas and electricity meters to connected thermostats and boilers. Jim Anning and Josep Casals will go through their experience building a unified platform with Apache Cassandra, Apache Spark and related technologies. Focus will be of the main lessons learnt and the things they wish they had known beforehand.
Are you an experienced B2B sales leader who feels the need for better revenue forecasts? Believe it or not, the solution may not be in a new CRM process or in the hiring of a new team member. There is a LOT of information in your current sales pipeline waiting to be unlocked. You can do that with little changes and lots of discipline.
