Extending js codemotion warsaw 2016

Francis Bourre

React, Angular, TypeScript… Over the past few years, all these names took part in a fashionable phenomenon, pushed by the big names of the web industry. But what if a parallel world exists beyond this marketed mirror? A better world where you can easily build flexible applications with reusable components. Bourre will explain the right philosophy for building flexible applications with reusable components. As well, he will showcase the few tools to better achieve these goals, pushing forward the limits of the JS eco-system.

Studio 5000® Application Code Manager: Introduction and Demonstration

Rockwell Automation

This session combines presentation with instructor-led demonstration of Application Code Manager (ACM) capability. This session will cover how to quickly build your automation projects using reusable code stored in libraries. See how configuration, not programming, is used by selecting library objects (control modules, equipment modules, etc.) and providing configuration data, such as object name and descriptions, equipment set points, control interlocks, I/O mapping, etc., required for your project. Once all the configuration, not programming, is provided the project will be built (ACD file) which can be downloaded to a controller.

Codemotion

The future of e-commerce requires personalized content for each individual customer. With over 20 million active users, Zalando is facing the challenge of making its frontends more scalable in order to achieve this goal. We brought a solution from the backend to the frontend: microservices. In addition to creating Project Mosaic (https://www.mosaic9.org)—our solution for modular frontends—and using a toolbox of modern web technologies like React and Webpack, we built an architecture that can scale to virtually any size and even support targets other than the browser.

Big Data Spain

The Big data ecosystem is thriving. Driven by the productivity of the open source approach and by the markets, the community is constantly developing new tools, plugins and functionalities to improve and simplify all the aspects of data science. Unfortunately the life of system administrators is increasingly becoming more complicated. From the selection of the right architecture to the installation of the tools, their configuration and testing, a very large amount of time needs to be spent setting up the system. The burden is even more demanding when the infrastructure has high availability and strong security requirements. For the enterprise this means committing a considerable amount of resources to the maintenance of the systems, which require dedicated Unix sysadmin support. At Keedio we like simplicity, and in this workshop we shall demonstrate how you can, within minutes, easily deploy a full big data stack which is highly available and secure. Session presented at Big Data Spain 2015 Conference 16th Oct 2015 Kinépolis Madrid http://www.bigdataspain.org Event promoted by: http://www.paradigmatecnologico.com Abstract: http://www.bigdataspain.org/program/fri/slot-38.html

Kubernetes buildpacks - from a source code to the running OCI container with ...

PROIDEA

Kubernetes nowadays quickly outgrows Cloud Foundry. People even say containers are eating the software world. From the operator perspective the change is very much appreciated, but on the other hand there is a group which may have lost a very useful feature - a single click to run source, so called 'cf push'. Can't we do the same in Kubernetes? Nothing could be more wrong! In this presentation Adam will show how this kind of tool can be implemented - from the source code packaging, through running the temporary builder in the and using OCI buildpacks.io pack to create resulting image and finally pushing it to the docker repository, running in the Kubernetes and exposing to the world.

First Steps with Globus Compute Multi-User Endpoints

Globus

In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.

Providing Globus Services to Users of JASMIN for Environmental Data Analysis

Globus

JASMIN is the UK’s high-performance data analysis platform for environmental science, operated by STFC on behalf of the UK Natural Environment Research Council (NERC). In addition to its role in hosting the CEDA Archive (NERC’s long-term repository for climate, atmospheric science & Earth observation data in the UK), JASMIN provides a collaborative platform to a community of around 2,000 scientists in the UK and beyond, providing nearly 400 environmental science projects with working space, compute resources and tools to facilitate their work. High-performance data transfer into and out of JASMIN has always been a key feature, with many scientists bringing model outputs from supercomputers elsewhere in the UK, to analyse against observational or other model data in the CEDA Archive. A growing number of JASMIN users are now realising the benefits of using the Globus service to provide reliable and efficient data movement and other tasks in this and other contexts. Further use cases involve long-distance (intercontinental) transfers to and from JASMIN, and collecting results from a mobile atmospheric radar system, pushing data to JASMIN via a lightweight Globus deployment. We provide details of how Globus fits into our current infrastructure, our experience of the recent migration to GCSv5.4, and of our interest in developing use of the wider ecosystem of Globus services for the benefit of our user community.

Understanding Globus Data Transfers with NetSage

Globus

NetSage is an open privacy-aware network measurement, analysis, and visualization service designed to help end-users visualize and reason about large data transfers. NetSage traditionally has used a combination of passive measurements, including SNMP and flow data, as well as active measurements, mainly perfSONAR, to provide longitudinal network performance data visualization. It has been deployed by dozens of networks world wide, and is supported domestically by the Engagement and Performance Operations Center (EPOC), NSF #2328479. We have recently expanded the NetSage data sources to include logs for Globus data transfers, following the same privacy-preserving approach as for Flow data. Using the logs for the Texas Advanced Computing Center (TACC) as an example, this talk will walk through several different example use cases that NetSage can answer, including: Who is using Globus to share data with my institution, and what kind of performance are they able to achieve? How many transfers has Globus supported for us? Which sites are we sharing the most data with, and how is that changing over time? How is my site using Globus to move data internally, and what kind of performance do we see for those transfers? What percentage of data transfers at my institution used Globus, and how did the overall data transfer performance compare to the Globus users?

TROUBLESHOOTING 9 TYPES OF OUTOFMEMORYERROR

Tier1 app

Even though at surface level ‘java.lang.OutOfMemoryError’ appears as one single error; underlyingly there are 9 types of OutOfMemoryError. Each type of OutOfMemoryError has different causes, diagnosis approaches and solutions. This session equips you with the knowledge, tools, and techniques needed to troubleshoot and conquer OutOfMemoryError in all its forms, ensuring smoother, more efficient Java applications.
