You have your shiny new DSL up and running thanks to the Eclipse Modeling Technologies and you built a powerful tooling with graphical modelers, textual syntaxes or dedicated editors to support it. But how can you see what is going on when a model is executed ? Don't you need to simulate your design in some way ? Wouldn't you want to see your editors being animated directly within your modeling environment based on execution traces or simulator results?
In this talk we are going to present a preview of Spring Roo 2.0, a rewrite of the code generating tool for the development of Java web applications based on current Spring technologies like Spring Boot, Spring Data, etc.

Modeling avengers – open source technology mix for saving the world econ frCédric Brun
Planet earth is facing massive challenges: global warming and scarcity of natural resources among others. Those challenges are reaching a level of complexity unknown yet and trying to address those requires deep scientific understanding, real world data, specialized tools, inter-disciplinary collaboration and the ability to evaluate “What If” scenarios.
In collaboration with scientists from INRA (the French National Institute for Agricultural Research) we experienced one of those challenges: the use of natural resources for agricultural activities, especially water consumption. While the scientists insight was required in smart technologies like smart farms, this understanding was required to be expressed at an higher level of abstraction through specific tooling. They felt that providing highly dedicated tools with a small budget would require super powers. To us modeling people it looked like a very good fit for DSL’s (Domain Specific Languages), hence suitable for an experiment : let’s build specific modeling tools for smart farming systems!
This experiment represents a few days of work bringing open-source technologies together: EMF, Xtext, Sirius, Gemoc (a model debugging environment, including specific features for concurrency constraints), OptaPlanner (a constraint satisfaction solver from the JBoss community) and Acceleo, resulting in a collection of Eclipse based tools for farming systems (published on github). Just like in The Avengers, each technology bring its own capability but it is the amalgamation of all of them which lead to amazing power!
The session will start with a demo of the Smart Farming System Tooling, an environment to model, analyze and simulate an agricultural exploitation, biomass growth and water consumption based on user input and open data. Then we will dig deeper in how the technologies are mixed and used, among other questions: which of the textual or graphical syntax is better suited for a given aspect? how can we achieve a “perfect blend” of those syntaxes? how OptaPlanner and EMF can create a powerful synergy? how data from INRA can be structured and fed into the tool?
This slides describes the basic concepts of industrial-strength compiler design. This includes basic concept of static single-assignment form (SSA) and various optimizations such as dead code elimination, global value numbering, constant propagation, etc. This is intend for a 150 minutes undergraduate compiler class.

PyLadies Talk: Learn to love the command line!Blanca Mancilla
This talks aims to uncover some of the magic powers of scripting and the command line.
I'll share with you some of my experience using the shell to schedule backups of a git repository or to find strings in files of unknown name and location.
And then you might see that it is a tough love!
A talk on static code analysis tools such as jshint, jscs, and eslint and how to use them to write good (stylish) code. Also introducing tools to enforce using the correct style via editorconfig or js-beautify to minimize efforts to write good code.
Serge Guelton and Pierrick Brunet (Namek): “Pythran: Static Compilation of Parallel Scientific Kernels”
Abstract: As the use of Python coupled to Numpy/SciPy for numerical computation increases, many tools to optimize performance have emerged. Indeed, this duo has relatively poor performance when compared to scientific codes written in legacy languages like C or Fortran. Cython, Numba, numexpr and parakeet belongs to this new compiler ecosystem. And so does Pythran, a Python to C++11 translator for scientific Python.
Pythran uses a static compilation approach a la Cython, but with full backward compatibility with Python. It does not only turns Python code into C++ code, it also performs Python/Numpy specific optimizations, generates calls to a parallel, vectorized runtime and makes it possible to write OpenMP annotation in the original Python code. It supports a large range of Numpy functions and can combine them in efficient ways: it can optimize highlevel modern Python/Numpy codes and not only Fortran with a Python flavor ones.
This talk presents the existing compilation approach and optimization opportunities for numerical Python, their strengths and weaknesses, then focus on the specificities of the Pythran compiler.
No Flex Zone: Empathy Driven DevelopmentDuretti H.
The technology industry has a bad rap. Sexism and misogyny run rampant. Marginalized groups get railroaded. Out-of-touch companies look to make as much money as ruthlessly as possible, all while exploiting others and passing it off as "disruption". Our industry is losing sight of what it could be. Technology, at its heart, has always been aspirational - about dreaming up the impossible and willing it into existence. This talk will discuss what can bring us back from the brink: empathy. Empathy for the people that use the things we make, for our non-technical teammates, and for our fellow engineers.
10 Billion a Day, 100 Milliseconds Per: Monitoring Real-Time Bidding at AdRollBrian Troutwine
This is the talk I gave at Erlang Factory SF Bay Area 2014. In it I discussed the instrumentation by default approach taken in the AdRoll real-time bidding team, discuss the technical details of the libraries we use and lessons learned to adapt your organization to deal with the onslaught of data from instrumentation.
Type systems are associated with most programmers with something really hard, strongly academic and difficult to understand, and not useful in the daily life of the developer. I will try to change that, at least partly. While I do not believe that a great knowledge of type systems will make you much more productive, I will try to dispel the myth that it is something difficult and incomprehensible. In an accessible and interactive way, I will introduce a little "Computer Science" which can help us understand why some of the languages we use are designed in a way that's different.
First of all, we will answer the truth - how much "Typed" TypeScript really is?
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?

How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.

Innovating Inference - Remote Triggering of Large Language Models on HPC Clus...Globus
Large Language Models (LLMs) are currently the center of attention in the tech world, particularly for their potential to advance research. In this presentation, we'll explore a straightforward and effective method for quickly initiating inference runs on supercomputers using the vLLM tool with Globus Compute, specifically on the Polaris system at ALCF. We'll begin by briefly discussing the popularity and applications of LLMs in various fields. Following this, we will introduce the vLLM tool, and explain how it integrates with Globus Compute to efficiently manage LLM operations on Polaris. Attendees will learn the practical aspects of setting up and remotely triggering LLMs from local machines, focusing on ease of use and efficiency. This talk is ideal for researchers and practitioners looking to leverage the power of LLMs in their work, offering a clear guide to harnessing supercomputing resources for quick and effective LLM inference.
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.

SOCRadar Research Team: Latest Activities of IntelBrokerSOCRadar
The European Union Agency for Law Enforcement Cooperation (Europol) has suffered an alleged data breach after a notorious threat actor claimed to have exfiltrated data from its systems. Infamous data leaker IntelBroker posted on the even more infamous BreachForums hacking forum, saying that Europol suffered a data breach this month.
The alleged breach affected Europol agencies CCSE, EC3, Europol Platform for Experts, Law Enforcement Forum, and SIRIUS. Infiltration of these entities can disrupt ongoing investigations and compromise sensitive intelligence shared among international law enforcement agencies.
However, this is neither the first nor the last activity of IntekBroker. We have compiled for you what happened in the last few days. To track such hacker activities on dark web sources like hacker forums, private Telegram channels, and other hidden platforms where cyber threats often originate, you can check SOCRadar’s Dark Web News.

Globus Compute wth IRI Workflows - GlobusWorld 2024Globus
As part of the DOE Integrated Research Infrastructure (IRI) program, NERSC at Lawrence Berkeley National Lab and ALCF at Argonne National Lab are working closely with General Atomics on accelerating the computing requirements of the DIII-D experiment. As part of the work the team is investigating ways to speedup the time to solution for many different parts of the DIII-D workflow including how they run jobs on HPC systems. One of these routes is looking at Globus Compute as a way to replace the current method for managing tasks and we describe a brief proof of concept showing how Globus Compute could help to schedule jobs and be a tool to connect compute at different facilities.
Enhancing Research Orchestration Capabilities at ORNL.pdfGlobus
Cross-facility research orchestration comes with ever-changing constraints regarding the availability and suitability of various compute and data resources. In short, a flexible data and processing fabric is needed to enable the dynamic redirection of data and compute tasks throughout the lifecycle of an experiment. In this talk, we illustrate how we easily leveraged Globus services to instrument the ACE research testbed at the Oak Ridge Leadership Computing Facility with flexible data and task orchestration capabilities.
We describe the deployment and use of Globus Compute for remote computation. This content is aimed at researchers who wish to compute on remote resources using a unified programming interface, as well as system administrators who will deploy and operate Globus Compute services on their research computing infrastructure.
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.
Gamify Your Mind; The Secret Sauce to Delivering Success, Continuously Improv...Shahin Sheidaei
Games are powerful teaching tools, fostering hands-on engagement and fun. But they require careful consideration to succeed. Join me to explore factors in running and selecting games, ensuring they serve as effective teaching tools. Learn to maintain focus on learning objectives while playing, and how to measure the ROI of gaming in education. Discover strategies for pitching gaming to leadership. This session offers insights, tips, and examples for coaches, team leads, and enterprise leaders seeking to teach from simple to complex concepts.
In software engineering, the right architecture is essential for robust, scalable platforms. Wix has undergone a pivotal shift from event sourcing to a CRUD-based model for its microservices. This talk will chart the course of this pivotal journey.
Event sourcing, which records state changes as immutable events, provided robust auditing and "time travel" debugging for Wix Stores' microservices. Despite its benefits, the complexity it introduced in state management slowed development. Wix responded by adopting a simpler, unified CRUD model. This talk will explore the challenges of event sourcing and the advantages of Wix's new "CRUD on steroids" approach, which streamlines API integration and domain event management while preserving data integrity and system resilience.
Participants will gain valuable insights into Wix's strategies for ensuring atomicity in database updates and event production, as well as caching, materialization, and performance optimization techniques within a distributed system.
Join us to discover how Wix has mastered the art of balancing simplicity and extensibility, and learn how the re-adoption of the modest CRUD has turbocharged their development velocity, resilience, and scalability in a high-growth environment.

8. LIQUID OUTLET
Animates between routes transition
LIQUID WITH
Animates the transition between different models on the
same route
LIQUID BIND
{{liquid-bind someProp}} it's the equivalent of {{someProp}},
the helper animates between value changes
9. LIQUID IF
Works like the normal ember IF helper and animates when
the value changes from true to false or the opposite
LIQUID SPACER
Do not have an equivalent Ember helper
Do not search in transition map for matching

10. TRANSITION MAP
You can configure rules that govern which animations run at
any given moment.
The map must be located in app/transitions.js
It gives access to functions:
transition creates a transition rule with one or more
constraints and a use statement.
setDefault is used to provide default setting to Velocity.js
(e.g duration, easing, etc.)
11. CREATE RULES FOR ROUTES
fromRoute, toRoute, withinRoute are available for the
