Все когда-либо писали парсеры, но многие так и не знают как спарсить HTML без регулярных выражений. Очень длительное время концепция парсинга языков с рекурсивной грамматикой для меня была черной магией, а люди которые занимаются разработкой компиляторов и предметно-ориентированных языков вовсе казались волшебниками. Но это оказалось не так и сложно. В моем докладе я хочу вам рассказать о том что такое парсеры в целом, зачем они нужны и какие они бывают, а самое главное -- покажу как перейти от традиционных методик их написания к более удобному и понятному функциональному способу. В ходе презентации мы также напишем рабочий JSON парсер в качестве proof of concept.

A preview of OW2 Market Place. OW2con'15, November 17, Paris. OW2
This presentation introduces the Market Place developped in the framework of the AppHub European collaborative project. This Market Place is today made available to all OW2 projects. What are the incentives for an OW2 project to join this Market Place? How can they be part of it? The AppHub Store and Factory are explained during the talk.
Participating in AppHub, the European Open Source MarketplaceOW2
AppHub is the European Open Source marketplace. AppHub identifies and positions software components within the Open Cloud Directory to help users find and implement the software outcomes of your projects more easily. Open source software is a powerful enabler for collaborative innovation. However, making the source available does not automatically attract contributors or grant immediate market access. AppHub is designed to provide an distribution channel that addresses these issues, making it easier for open source projects to connect with their potential markets. Essentially, AppHub brings the market to you. This presentation will provide an overview of AppHub and help OW2 project leaders understand how they can participate in, and benefit from, the AppHub marketplace.
Spatial Sound 4: Getting the Best Surround AroundRichard Elen
Part 4 of a series of four presentations that formed the basis of my short course on spatial audio for artists at the Music Department, Ionian University, Corfu, July 2008
The Open Cloud Computing Interface is a specification from Open Grid Forum which aims at interoperability between cloud computing providers. Based on a formal meta-model, it can be easily extended to address every kind of service oriented application.
RESTLess Design with Apache Thrift: Experiences from Apache Airavatasmarru
Apache Airavata is software for providing services to manage scientific applications on a wide range of remote computing resources. Airavata can be used by both individual scientists to run scientific workflows as well as communities of scientists through Web browser interfaces. It is a challenge to bring all of Airavata’s capabilities together in the single API layer that is our prerequisite for a 1.0 release. To support our diverse use cases, we have developed a rich data model and messaging format that we need to expose to client developers using many programming languages. We do not believe this is a good match for REST style services. In this presentation, we present our use and evaluation of Apache Thrift as an interface and data model definition tool, its use internally in Airavata, and its use to deliver and distribute client development kits.

OCCiware A Formal and Tooled Toolchain For Managing Everything as a Service OCCIware
The OCCIware project aims at building a comprehensive engineering toolchain for managing Everything as a Service (XaaS). The objective is to dramatically decrease the cost of using or providing XaaS by breaking silos between layers and domains of Cloud Computing. Leveraging the Open Cloud Computing Interface (OCCI) standard-to-be, we are developing a model-driven engineering studio as well as generic runtimes adapted to various domains: Linked Open Data, cloud computing, platform as a service, Big Data, connected objects, etc. The project, funded by French Ministry of Industry, involves 10 academic and industrial partners and is supervised by a committee of 11 top scientists and industry experts.
This presentation was created as an introduction to the Apache NiFi project; to be followed by “Lab 0” of the “Realtime Event Processing in Hadoop with NiFi, Kafka and Storm” tutorial hosted here: http://hortonworks.com/hadoop-tutorial/realtime-event-processing-nifi-kafka-storm/#section_1
Why apache Flink is the 4G of Big Data Analytics FrameworksSlim Baltagi
Apache Flink is a community-driven open source and memory-centric Big Data analytics framework. It provides the only hybrid (Real-Time Streaming + Batch) open source distributed data processing engine supporting many use cases.
Flink uses a mixture of Scala and Java internally, has very good Scala APIs and some of its libraries are basically pure Scala (FlinkML and Table).
At its core, it is a streaming dataflow execution engine and it also provides several APIs for batch processing (DataSet API), real-time streaming (DataStream API) and relational queries (Table API) and also domain-specific libraries for machine learning (FlinkML) and graph processing (Gelly).
In this talk, you will learn in more details about:
What is Apache Flink, how it fits into the Big Data ecosystem and why it is the 4G (4th Generation) of Big Data Analytics frameworks?
How Apache Flink integrates with Apache Hadoop and other open source tools for data input and output as well as deployment?
Why Apache Flink is an alternative to Apache Hadoop MapReduce, Apache Storm and Apache Spark? What are the benchmarking results between Apache Flink and those other Big Data analytics frameworks?
Real time cloud native open source streaming of any data to apache solrTimothy Spann
Real time cloud native open source streaming of any data to apache solr
Utilizing Apache Pulsar and Apache NiFi we can parse any document in real-time at scale. We receive a lot of documents via cloud storage, email, social channels and internal document stores. We want to make all the content and metadata to Apache Solr for categorization, full text search, optimization and combination with other datastores. We will not only stream documents, but all REST feeds, logs and IoT data. Once data is produced to Pulsar topics it can instantly be ingested to Solr through Pulsar Solr Sink.
Utilizing a number of open source tools, we have created a real-time scalable any document parsing data flow. We use Apache Tika for Document Processing with real-time language detection, natural language processing with Apache OpenNLP, Sentiment Analysis with Stanford CoreNLP, Spacy and TextBlob. We will walk everyone through creating an open source flow of documents utilizing Apache NiFi as our integration engine. We can convert PDF, Excel and Word to HTML and/or text. We can also extract the text to apply sentiment analysis and NLP categorization to generate additional metadata about our documents. We also will extract and parse images that if they contain text we can extract with TensorFlow and Tesseract.
Redfish is an IPMI replacement standardized by the DMTF. It provides a RESTful API for server out of band management and a lightweight data model specification that is scalable, discoverable and extensible. (Cf: http://www.dmtf.org/standards/redfish). This presentation will start by detailing its role and the features it provides with examples. It will demonstrate the benefits it provides to system administrator by providing a standardized open interface for multiple servers, and also storage systems.
We will then cover various tools such as the DMTF ones and the python-redfish library (Cf: https://github.com/openstack/python-redfish) offering Redfish abstractions.

OW2 Association Européenne aux racines grenobloises, transformer l'industrie ...OW2
Connaissez-vous OW2 ? Aventure commencée en 1999 à Grenoble sur la base d'un consortium industriel dédié au middleware open source, devenu association sans but lucratif d'échelle européenne en 2006 sous le nom d'OW2, nous agissons pour la diffusion du libre dans le monde professionnel depuis plus de 20 ans.
OW2 compte des adhérents de toute taille : 2.600 individuels en adhésion gratuite, et 30 institutionnels, de la TPE unipersonnelle à Orange, Microsoft ou Huawei, de l'Inria ou le Fraunhofer Fokus à la Gendarmerie Nationale ou la ville de Paris.
Nos projets sont plus célèbres que nous : ASM, Centreon, Lutece, PrestaShop, Sympa ou Rocket.Chat vous diront peut-être quelque chose ?
Philosophiquement, OW2 se trouve quelque part entre Eclipse et Apache : culture technique, infrastructure d'hébergement et d'assistance pour les projets, sur la ligne de crête entre l'esprit du libre et les contraintes du business, nous sommes un acteur de l'économie sociale, persuadé que l'open source est central dans une transformation sociétale nécessaire qui ne pourra se faire sans l'adhésion du monde industriel et académique.
A un tournant de notre histoire, nous investissons le créneau de la qualité industrielle des projets avec notre méthodologie "Market readiness Levels", et la gouvernance de l'open-source comme membre fondateur de l'OSPO Alliance (ospo.zone) et éditeur du guide méthodologique "OSS Good Governance handbook".
Ne nous y trompons pas : OW2 est un acteur éminemment politique, porteur d'une vision fondée sur la transformation du monde professionnel et de ses valeurs par le code et la coopération. Et cette présentation, avec un survol de notre histoire, adhérents, initiatives et projets, est également l'occasion d'en débattre.
This presentation by Cedric Thomas (OW2 CEO) details three OW2 initiatives to engage with mainstream open source software users, including the H2020 ReachOut project, Market Readiness and Good Governance.
Towards a sustainable solution to open source sustainability, OW2online20, Ju...OW2
A few years ago, Heartbleed epitomized a massive open source sustainability problem for critical parts of the internet infrastructure. The bug, which affected the popular OpenSSL cryptographic software library, notably compromised the confidentiality of 4.5 million US patient records and cost the industry an estimated $500M. It was soon revealed that the root cause of the issue was that OpenSSL was precariously understaffed. Open source sustainability became a major theme overnight. Stories of maintainer burn-out made the headlines. And tentative solutions started to emerge, most of them donation-based. In this talk we’ll explore a number of existing strategies to fund open source and make it more sustainable, from patronage to dedicated ad networks. And we’ll defend the idea that the best path to open source sustainability is to help companies understand the tangible business value they can get from contributing to open source.

Open Source governance and the Eclipse Foundation, OW2online, June 2020OW2
Presentation by Gael Blondelle, Managing Director at Eclipse Foundation.
Abstract:
In this talk, we will cover two complementary topics: The different Eclipse projects related to Open Source governance, like Eclipse SW360, SW360 Antenna, and Eclipse Steady, as well as the opportunity to leverage SW360 as the core of a larger Open Source governance initiative.
The Eclipse IP Process that has been applied to hundreds of Eclipse projects for more than 15 years and is going through a modernization process that involves both simplification from the developer point of view, and openness to new source of trusted data like Clearly Defined.
Open source contribution policies, OW2online, June 2020OW2
Open source contribution policies are long, boring, overlooked documents, that generally suck. They're designed to protect the company at all costs. But in the process, end up hurting engineering productivity, and morale. Sometimes they even unknowingly put corporate IP at risk.
But that's not inevitable.
It's possible to write open source contribution policies that make engineers lives easier, boost morale and productivity, reduce attrition, and attract new talent. And it's possible to do so while reducing the company's IP risk, not increasing it.
In this talk, we'll look at the general structure of contribution policies, examples in the wild, and tactics to make them suck less.
We'll also look at how to turn these policies into self-service software, preventing the tedious email back and forth between engineering and legal in most cases and making open source contribution a breeze. Presentation by Tobbie Langel, UnLockOpen.
Software development at scale, pandemic lockdown and oss ecosystems, OW2onlin...OW2
Presentation by Jose Manrique, CEO at Bitergia.
Abstract: 2020 has started intense for many countries. It's been just a few months, but the things we have lived make us feel like it's been years. Covid-19 pandemic has hit everywhere and forced many people to work from home. If you were lucky enough to be in one of these modern companies that have adopted digital transformation years ago, would that be a problem? Many people have thought it wasn't, but it has really been. And what about the rest of the software developers involved in companies not ready for remote work at all?
It's been said that nothing has boosted more companies' digital transformation than covid-19. But, are their managers ready for such change? Managing software development at scale is not an easy task, and this pandemic has disrupted the way projects are being developed in many companies.
During this talk, I would like to share lessons learned from open source development at scale that might help companies to adapt to these changes. But more specifically, lessons about how software development analytics help managers to understand collaborative remote work.
Overview of the OpenChain Reference Tooling Work Group, OW2online20, June 2020OW2
Presentation by Olivier Fendt, Senior Manager Open Source Software at Siemens.
Abstract: The well-known OpenChain project launched in Sept 2019 a Tooling Group. The objective of this group is to realize a turn-key Open Source toolchain for Open Source Compliance, which is / can be easily integrated in the software development CI/CD pipelines. The Tooling Group uses open source principles to accomplish this, creating a meritocracy producing real world solutions for real world challenges, and sharing these results with all interested parties. The presentation gives an overview of the Tooling group its objectives, the areas of focus, the current state and future plans.
Open Source Compliance at Orange, OW2online, June 2020OW2
Presentation by Nicolas Toussaint, Software Architect, Orange.
Abstract: Orange and Orange Business Services have turned to full open source solutions to tackle the complex problem of respecting the open source legal compliance constraints.
This talk presents the journey undertaken the past few years to build and improve the existing tooling and processes to make compliance validation possible, as well as allow overseeing progresses.
Ideas, methods and tools for OSS Compliance assessment, OW2online, June 2020OW2
Presentation by Boris Baldassari, Consultant, Castalia Solutions.
Abstract: While Open Source Software has become mainstream, the understanding of its key principles, from ethics and collaboration to governance and community management, is gaining more interest and attention. There is a comprehensive volume of studies and reports backing up our individual and collective experience, yet we still cannot reliably measure these characteristics, and even less clearly define or assess them.
In an attempt to build up confidence and foster maturity in this area, this talk will look at the various existing models and metrics related to OSS compliance and governance, and build upon them to propose methods and tools for their evaluation and analysis. We will discuss the requirements and essential questions to ask, offer guidelines for implementation and suggest efficient ways to present results.
Intelligent package management with FASTEN, OW2online, June 2020OW2
Presentation by Amir Mir, TUDelft.
As recent events, such as the leftpad incident and the Equifax data breach, have demonstrated, dependencies on networks of external libraries can introduce projects to significant operational and compliance risks as well as difficult to assess security implications. FASTEN introduces fine-grained, method-level, tracking of dependencies on top of existing dependency management networks. In our talk, we will present how FASTEN works on top of the Rust/Cargo and Java/Maven ecosystems.
DECODER, a Smarter Environment for DevOps Teams , OW2online, June 2020OW2
The DECODER project simplifies software library and component reuse, while ensuring that they will behave as expected by the developer. The DECODER central database (PKM) stores code-related artifacts and establish bindings between them, notably by generating formal specification from informal requirements or semi-formal models from source code. Presentation by Virgile Prevosto, CEA List.
Enabling DevOps for IoT software development, powered by Open Source, OW2onli...OW2
Presentation by Hui Song, Senior Scientist, SINTEF. We would like to share our research journey towards enabling DevOps for IoT applications, and how Open Source makes the journey feasible and fun.
DevOps is widely adopted for developing cloud applications, which supports developers in continuously placing software changes directly to production. As companies are including IoT and Edge devices into their IT infrastructures, supporting DevOps for IoT is a must. However, IoT challenges some fundamental assumptions behind DevOps, such as the homogeneous infrastructure and centralized governance, and therefore, breaking-through research is needed. Funded by H2020, 30 people from 12 partners crossing academia and industry gathered to solve these fundamental challenges, which results in full-stack open source tools for automatic deployment, learning-based operation and security monitoring of IoT applications, and risk management of the development process. The tools are evaluated on industrial use cases in intelligent transportation, smart building, and eHealth.
The mass open source tools and communities around IoT development provides the sound foundation for this design research and the opportunities for the further exploitation of the results. In particular, we are proud of spinning off a start-up to commercialize the risk management services in the open source + SaaS model.
Upcoming Challenges in Artificial Intelligence Research and Development, OW2o...OW2
Artificial Intelligence is now smarter than ever, showing human-like abilities at complex tasks such as images classification or natural language processing.
But despite its recent advances, it's still not a silver bullet. This talk will present a few challenges in the research and development of artificial intelligence that slow down its progress and adoption. In particular, problems around fairness, the training of models and how to share them will be introduced as well as possible Free Software solutions. Presentation by Vincent Lequertier, PhD Student, Lyon UNiverversity.
Cacti and Big Data at Orange France, OW2online, June 2020OW2
We propose a walkthrough of current utilization of Open Source Software in capacity planning for the Orange network infrastructure.
The objective of our project is to have a platform that helps engineers to carefully plan the resources available to them as well as to correlate different incidents within remote parts of the infrastructure.
In order to achieve this we started using Cacti with the Spine collector which worked great, but Orange France is a very large company with many entities, each with its own governance, and so we began to see some limitations.
There was a need to centralize some information from different parts in Orange France as well as to integrate the equipment capacity and load values into BigData Orange.
In order to achieve this we developed the “Puits de donneés” platform completely based on Open Source Software.
The visualization and statistical analysis part is handled by Grafana while the ETL runs on Apache Software Foundation products like NiFi, Zookeeper and Ambari with a storage solution from MariaDB for which we did extensive performance tuning and customization due to the large amounts of data.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

Pagination
Authnz (tokens, etc), return codes, etc.
Finally...
One to rule them all ?
A single meta-model ?
Application level : data types (structures, relations, etc)

5. Let's speak about a standard ?
November 5th, 2014 erocci - Jean Parpaillon 5
6. Let's speak about a standard for REST
A standard
Is not a catalog of schemas
Is not a constraint for developers
Must be implemented (implementable)
A good standard
Should allow to concentrate on the design, not the
implementation details
Allow to build an ecosystem
Allow to accelerate the development, not the contrary

7. The Open Cloud Computing Interface
OCCI is typed
A ressource is an instance of a kind
A kind is a named list of typed attributes and actions
e.g. : compute : # cores (integer), RAM (float), etc
Attribute : name, type, default value, mutability, etc.
Action : an invocable operation on a ressource
Kinds are inheritable
November 5th, 2014 erocci - Jean Parpaillon 7
8. The Open Cloud Computing Interface
OCCI is extensible
Resource can be associated with mixins
Mixin: a named set of additional attributes and actions
e.g. : IPNetworkInterface adds IP, netmask, etc to a
network interface
User Mixin : aka « tags »
e.g. : http://example.com/occi/mixins#my_project1
November 5th, 2014 erocci - Jean Parpaillon 8
9. The Open Cloud Computing Interface
OCCI is relational
Links are ressources with additional attributes
occi.core.source : resource URI
occi.core.target : URI
A bounded collection is a list of ressources of the same
kind/mixin :
e.g. : GET /collections/compute/
An unbounded collection is a list of ressources with
same prefx :
e.g. : GET /myresources/
November 5th, 2014 erocci - Jean Parpaillon 9
10. The Open Cloud Computing Interface
OCCI is self-described
GET /-/ (capabilities)
List of supported kinds
List of supported mixins
Capabilities returns collection's URL
http://schemas.ogf.org/occi/infrastructure#compute →
/collections/compute/
November 5th, 2014 erocci - Jean Parpaillon 10
11. The Open Cloud Computing Interface
OCCI is meta-model based
Model consistency checking
Automatic model implementation
Rendering independant
text/plain, application/json, …
Transport independant
HTTP, ...
November 5th, 2014 erocci - Jean Parpaillon 11
12. OCCI Ecosystem
Framework
rOCCI (ruby)
occi4java (not maintained)
Specifc implementations
CompatibleOne
PyOCNI
OpenStack, OpenNebula,
etc
Limits
Models are
language/extensions/lib
dependant

13. Why erocci ?
Generic : a framework to build OCCI applications
Less code, more design
Small, tested, reliable
Easy to deploy
Scalable
Runs embedded in connected objects (IoT)
Scales out to serve millions of users
Extensible
November 5th, 2014 erocci - Jean Parpaillon 13
15. Genericity
Only OCCI meta-model is hard-coded
Everything is pluggable :
Authentication mechanism
Transport protocol (HTTP, XMPP, etc)
Data sources (backends)
Allow composition of services by plugging data
sources (backends) at runtime
November 5th, 2014 erocci - Jean Parpaillon 15
16. Less code, more design
A schema for ressources' categories (kinds, mixins)
ACL-based authorizations
November 5th, 2014 erocci - Jean Parpaillon 16
17. Small, tested, reliable
Small
Around 12k lines
Tested
Continuous integration
Reliable
Erlang cowboy web server (LeoFS, MongooseIM, etc)
erlang/OTP platform provides fault tolerance
Process supervision
November 5th, 2014 erocci - Jean Parpaillon 17
18. Easy to deploy
All included erlang/OTP platform
Self contained : no web frontend
Just try it !
November 5th, 2014 erocci - Jean Parpaillon 18
19. Scalable
Thanks to erlang/OTP
Runs on RaspberryPI (~ 100 req/sec)
Scales out to a full cluster
November 5th, 2014 erocci - Jean Parpaillon 19
20. Extensible
Pluggable mechanisms
For those who don't like erlang
D-Bus backend API (experimental)
November 5th, 2014 erocci - Jean Parpaillon 20
21. (1) use case : a REST backend for blog
No need for ORM, web server, database, templating,
etc.
Design your model
Blog entry kind
User kind
Contribution kind (link between a user and an entry)
Choose a storage backend
Choose a transport (HTTP?)
Defnes ACL
And that's all
November 5th, 2014 erocci - Jean Parpaillon 21
22. (2) use case : API adapter
Backend API : write a new data source for your API
Erlang API
D-Bus API (any language)
In any case, implements CRUD operations
Choose a transport
Enjoy scalability, supervision, transports, ACL, etc.
November 5th, 2014 erocci - Jean Parpaillon 22
23. (3) use case : a protocol adapter
You have a resource oriented protocol and want to
expose it through HTTP/OCCI
Use occi_store for storing your data
erocci deals with storage, rendering, scalability, ...
November 5th, 2014 erocci - Jean Parpaillon 23
