Using Aspects for Language Portability (SCAM 2010)lennartkats
Software platforms such as the Java Virtual Machine or the CLR .NET virtual machine have their own ecosystem of a core programming language or instruction set, libraries, and developer community. Programming languages can target multiple software platforms to increase interoperability or to boost performance. Introducing a new compiler backend for a language is the first step towards targeting a new platform, translating the language to the platform\'s language or instruction set. Programs written in modern languages generally make extensive use of APIs, based on the runtime system of the software platform, introducing additional portability concerns. They may use APIs that are implemented by platform-specific libraries. Libraries may perform platform-specific operations, make direct native calls, or make assumptions about performance characteristics of operations or about the file system. This paper proposes to use aspect weaving to invasively adapt programs and libraries to address such portability concerns, and identifies four classes of aspects for this purpose. We evaluate this approach through a case study where we retarget the Stratego program transformation language towards the Java Virtual Machine.

Enforcing API Design Rules for High Quality Code GenerationTim Burks
[Co-presented with Mike Kistler, Architect for SDK Generation for the Watson Client Libraries]
The OpenAPI Specification is emerging as the leading standard for describing REST APIs. A key factor in the popularity of OpenAPI is the broad array of open source tools that it enables that create, manipulate, and publish documentation and code from OpenAPI descriptions. In this talk, we describe a configurable and extensible open source linter for OpenAPI that we are using to solve API code generation problems at IBM and Google. Our linter is based on Gnostic, an open source framework for working with API descriptions that was developed at Google and is available on GitHub.
OpenAPI itself is language-agnostic and is being used to generate code in a large set of popular programming languages. This generated code includes both server-side "stubs" and client libraries that are sometimes called software development kits (SDKs). IBM has begun to employ code generation for the Watson Developer Cloud SDKs and other companies are doing similar things, including Google, which generates client libraries from Google-specific API description formats. These teams have found that the quality of SDKs generated from API descriptions depends heavily on the quality of the descriptions. This goes far beyond mere syntactic compliance with a specification -- it involves proper API design, naming, and adherence to organization-wide design patterns. To address this, many companies have created API design guides. Some companies, such as Google and Microsoft, have published their API design guides externally, while others like IBM have kept theirs as internal documents. But to this point, verifying compliance with an API design guide has largely been a manual task. What is needed, we believe, is a configurable and extensible linter to check OpenAPI descriptions for conformance with rules derived from API design guides.
Remix Your Language Tooling (JSConf.eu 2012)lennartkats

EKON20 Conference, November 2016
Monolithic rich Windows applications are not enough for our customers. We are often requested to provide a web front-end, or a REST server to be consumed by mobile or thin clients. Integrating n-Tier architecture to an existing project is challenging. Some good practices, based on industry standards and proven design patterns (like uncoupling or SOLID) can be mind-breaker for RAD developers. In this session, we will define some architectural aspects of SOA, ORM and MVC/MVVM, and what our Open Source mORMot framework offers to ease this transition.
Why a DevOps approach is critical to achieve digital transformationAgileSparks
The Internet of Things, mobile, big data and social media have all contributed to the need for a digital transformation of the products and services that companies deliver. The main objective of DevOps is to tightly integrate development and operations to improve the velocity of launching both new and enhanced existing applications to market whilst meeting other essential criteria such as quality, security and efficiency. DevOps can be a key enabler to support the Digital Transformation journey towards the new era of a unified, consistent and channel neutral experience.

OSGi & Java in Industrial IoT - More than a Solid Trend - Essential to Scale ...mfrancis
OSGi Community Event 2016 Keynote Presentation by Robert Andres (Eurotech) & Walter Hofmann (Hitachi High Technologies)
With the promise of “real” IoT, the requirements for computational capabilities and agility at the edge demand IT-centric architectures and solutions that are based on open and industry standards. “IoT stacks” that are built on OSGi and Java’s solid foundation ensure effective modular software development and management on abstracted hardware.
Total cost of ownership in these IoT solutions matters a lot more than the simple combined hardware and software cost per edge node. Sophisticated software elements – including business intelligence tools, databases, and analytics packages – leverage data remotely and centrally to achieve the best results for customers. A perfect example of an analytics solution using such an approach is the predictive maintenance solution that Hitachi offers, leveraging Eurotech’s IoT hardware and software building blocks that heavily rely on OSGi.

Can i service this from my raspberry piThoughtworks
Infrastructure-related skills are essential for developers in cross-functional teams who build microservices for the cloud. Becoming proficient in infrastructure development is not just about understanding the hardware and software components on top of which applications run in the cloud. It's also about being able to use the tools that provide virtual access to this infrastructure and enable us to provision, configure, monitor it, and deploy applications to it. In this talk Gesa shares how building a Kubernetes cluster of Raspberry Pis and serving applications from it can help in acquiring fundamental infrastructure skills.
Today’s web and mobile app localization industry relies on numerous standards, libraries and file formats to facilitate the exchange between developers and translators. While some formats are somewhat sophisticated, others lack even the most basic features, like pluralization and contextualization. And most can’t offer support for more advanced localization features, like language cases.
The most common localization formats include Gettext PO, PHP Arrays, Android XML, YAML, .Net RESX, iOS Strings and many others. A typical developer today works with many frameworks - for instance a Laravel backend app (PHP Arrays) with Ember front end (i18n JS) and iOS mobile app (Strings). Since all standards have distinct syntax, in many cases translations cannot be shared across applications.
Translation Markup Language (TML) aims to solve both these problems by introducing a powerful extensible cross-platform syntax that offers support for pluralization, language contextualization, language cases, reusable decorators and much more. TML libraries are available for all major web and mobile platforms. TML allows translators to do in-context translations - where they can translate right from within the apps. TML libraries also eliminate the need for developers to ever deal with the resource files, as all extractions and translation substitution is done realtime and the resource files are only used as a transport between the apps and the Translation Exchange platform.
Translation Exchange stores all translations in Universal Translation Memory (UTM), a graph database which stores all translations with their context, tone, rank and other attributes for accurate matching. This allows translations to be shared across all apps in the Translation Exchange Network. The translation memories of each app are extracted from the UTM graph and are managed by their individual localization teams. During this presentation we will look at some of the features of TML and how it can be used to quickly translate a Ruby on Rails application into any number of languages using in-context translation tools. We will also look at how the data is stored and shared across applications using UTM.
One possible solution to ensure that your e-commerce site will not break during high-sales periods such as Black Friday or Christmas, is running JMeter distributed performance tests on Rancher.
This presentation was given during iQuest Keyboards & Mice event which took place in Craiova, Romania, on October 19th 2017.
Building and deploying LLM applications with Apache AirflowKaxil Naik
Behind the growing interest in Generate AI and LLM-based enterprise applications lies an expanded set of requirements for data integrations and ML orchestration. Enterprises want to use proprietary data to power LLM-based applications that create new business value, but they face challenges in moving beyond experimentation. The pipelines that power these models need to run reliably at scale, bringing together data from many sources and reacting continuously to changing conditions.
This talk focuses on the design patterns for using Apache Airflow to support LLM applications created using private enterprise data. We’ll go through a real-world example of what this looks like, as well as a proposal to improve Airflow and to add additional Airflow Providers to make it easier to interact with LLMs such as the ones from OpenAI (such as GPT4) and the ones on HuggingFace, while working with both structured and unstructured data.
In short, this shows how these Airflow patterns enable reliable, traceable, and scalable LLM applications within the enterprise.

Listen to the keynote address and hear about the latest developments from Rachana Ananthakrishnan and Ian Foster who review the updates to the Globus Platform and Service, and the relevance of Globus to the scientific community as an automation platform to accelerate scientific discovery.
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.
Developing Distributed High-performance Computing Capabilities of an Open Sci...Globus
COVID-19 had an unprecedented impact on scientific collaboration.

Informed by our team’s work in applying high-performance computing in support of public health decision makers during the COVID-19 pandemic, we present how Globus technologies are enabling the development of an open science platform for robust epidemic analysis, with the goal of collaborative, secure, distributed, on-demand, and fast time-to-solution analyses to support public health.
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.

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.

4. Machine and the Machine Code
❊ Logic implemented by Circuits
❊ Behavior specified by Architecture
❊ Capability abstracted by Instructions
❊ Instructions encoded in bits
❊ Code and Data referred by address
💻
6. Benefits
❊ Fast and Powerful
❊ Direct access to devices
❊ Little code transformation
❊ Low resource consumption
Drawbacks
♨ Lacks portability
♨ Code maintenance difficult
♨ Hard to read
♨ Un-named data
♨ Hard to debug issues
♨ Very little runtime checks
💉 🔌
7. C – A thin wrapper around Assembly
❊ Arithmetic: +, -, *, /, +=, ++
❊ Copy: =, memset(), strcpy()
❊ Compare: ==, !=, <, >, >=
❊ Control: if, for, switch, (), return
❊ Port access: read(), write()
❊ CAS: mutex, semaphore, conditions
🚀
8. C – Often as powerful as Assembly
unsigned long mytime()
{
unsigned long time;
__asm__ volatile (”rdtsc”:"=A" (time));
return time;
}

31. Summary
❊ Ideal feature balances expressiveness with commutability
❊ A Seamless, Silky route from the feature to the platform
❊ It is OK to be Polyglot
❊ Each language specializes around a central theme
❊ Keep one eye on the intended workload, and other on the
underlying system
❊ Find the right tool for each jobs, and fuse them
32. Want to build a new Language?
❊ Obvious Challenge: Huge Initial Investment
❊ Build Language Runtime before building a Language:
Platform Abstraction
Memory management
Dynamic Compiler
Diagnostic support
