Being functional in PHP (PHPDay Italy 2016)David de Boer
Functional programming, though far from new, has gained much traction recently. Functional programming characteristics have started to appear in the PHP world, too. Microframeworks such as Silex and Slim, middleware architectures such as Stack and even standards such as PSR-7 rely on concepts such as lambdas, referential transparency and immutability, all of which come from functional programming. I’ll give you a crash course in Erlang, a pragmatic functional language to make you feel familiar with the functional paradigm. By comparing code samples between Erlang and PHP, you’ll find out how you can employ functional programming in your PHP applications where appropriate. You’ll see that functional programming is nothing to be scared of. On the contrary, understanding its concepts broadens your programming horizon and provides you with valuable solutions to your problems.

Example of using Kotlin lang features for writing DSL for Spark-Cassandra connector. Comparison Kotlin lang DSL features with similar features in others JVM languages (Scala, Groovy).
In this session Max Kleiner shows four groups of the ML: Regression, Dimension Reduction, Clustering and Classification. ML recognizes patterns and laws in the learning data. Most ML projects allegedly fail due to lack of data consolidation and due to lack of hypothesis. On the basis of the well-known IRIS dataset the 4 groups with 4 algorithms each are gone through and this lack is avoided.
Introduction to Functional Programming with Haskell and JavaScriptWill Kurt
Presentation give to NNSDG on 8/26/2010
Functional programming is often seen as either difficult and academic. Languages such as Haskell, while incredible powerful, don't do much to dismiss this claim. However anyone that's used JavaScript has written a lambda function, and a pretty impressive amount of purely functional code can be implemented in JavaScript. Using these to languages this presentation introduces the fundamentals of functional programming.
Notebooks such as Jupyter give programming languages a level of interactivity approaching that of spreadsheets.
I present here an idea for a programming language specifically designed for an interactive environment similar to a notebook.
It aims to combining the power of a programming language with the usability of a spreadsheet.
Instead of free-form code, the user creates fields / columns, but these can be combined into tables and object classes.
By decoratively cycling through field elements, loops and other programming constructs can be created.
I give examples from classical computer science, machine learning and mathematical finance, specifically:

First Steps with Globus Compute Multi-User EndpointsGlobus
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.

Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.
Providing Globus Services to Users of JASMIN for Environmental Data AnalysisGlobus
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 NetSageGlobus
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?
