Many people are drawn into OSGi because it provides class loaders on steroids, however, one of the often overlooked feature of OSGi is the Service Registry and the (µ)service model. µServices provide a much more powerful alternative to the traditional Java factories and listeners in your code or xml, which are the usual culprits for class loading headaches. Alas, you need to migrate your application to OSGi first in order to take advantage of µServices which would make it so much easier to migrate your application to OSGi in the first place. The idea of PojoSR (a.k.a OSGi Lite) is to remedy this situation by providing OSGi without the module layer. PojoSR is based on Apache Felix and runs in any standard Java environment: from the class path, inside a WAR, wherever your current Java runs because it never touches a class loader. It allows any application built in Java to reap the benefits of service-based modularity without first having to rid existing code of any class loader tricks. This approach also allows, many existing bundles work out of the box - just by adding them to the class path (PojoSR will detect bundles on the class path and execute their activators). It works so well that OSGi is thinking of standardizing this approach. This talk will show you how you can take advantage of µServices using PojoSR and present some examples where µServices and PojoSR wore used to modularize and OSGi'fy an existing application.
Modern HA applications in nowadays are developed with set of small focused and discrete Microservices. It's a trending concept and opens/solves questions like maintenance, scaling, live-deployments, security, fault-tolerance etc.
For a long time bytecode weaving in OSGi has been a cumbersome process. Using it's internal hooks Equinox has supported basic transformation since version 3.2, but there has still been no simple, standard way to enhance classes and add new dependencies to the bundle that contains them. The new OSGi WeavingHook whiteboard pattern, which allows any OSGi bundle, not just an Equinox framework extension, to weave classes from, and add dependencies to, other OSGi bundles. Also new in OSGi is the opportunity to scan the classpath of an OSGi bundle. Whilst the isolated, modular classpath of an OSGi bundle provides an excellent system for building Java applications, many extenders and libraries need to be able to search for classes or resources within the bundle. This function further aids weaving implementations by allowing them to search for resources, class and package name patterns, and other configuration without requiring specific metadata to be present. As the lead author for the Bytecode weaving design within the OSGi Alliance, and a committer in the Apache Aries project, Tim will use his expertise to demonstrate the power and flexibility of WeavingHooks, particularly in conjunction with the latest OSGi updates for classpath scanning. Drawing on real-world examples from the Apache Aries project Tim will use real-world examples to prove that first-class weaving .support is now available in OSGi
OSAmI-Commons – an OSGi based platform supporting Open Ambient Intelligence f...mfrancis
he research project OSAmI Commons, running under ITEA and supported by national ministries, is based on OSGi and has focussed on the establishment of an open modular platform that enables industry players to use and exchange modular applications as needed.
In order to enable this marketplace the project has deployed the commonly defined platform in the industries of Ambient Assisted Living (a virtual rehabilitation program that will be further developed by a hospital), Sustainability (The green building INEED 3 is a reference architecture for low consumption buildings), Smart Home (Business solutions for sensor networks), Telematics (Smart City Services that are exploited with Turkish Telecom), Edutainment (Content recommendations that are commercialised by a Cable company), and the creation and deployment of tools (e.g. the Eclipse Libra Tool for the enterprise) to support the common platform. The presentation will focus on the benefits that OSGi provided, and examples on how this platform can be further exploited.

OSGi Community Event 2013 (http://www.osgi.org/CommunityEvent2013/Schedule)
ABSTRACT
One of the attractive qualities of OSGi is its role in enabling technologies that adopt it to manage the cost of their own success. Anything that gains adoption - in technology or elsewhere - picks up baggage as a result and needs to figure out how to deal with current installations while expanding in new directions. The WebSphere platform has been around for almost as long as Java and knows a thing or two about baggage but still manages to travel to many places with just a carry-on allowance. We adopted OSGi internally 8 years ago and have gradually increased our exploitation with each passing release, most recently and deeply with the lightweight WAS Liberty Profile. It hasn't all been plain sailing and we learned from a number of mistakes made along the way. When WebSphere Application Server first adopted OSGi it had over 10 million lines of code in a modest number of huge JARs. The engineering effort to modularize that into a “sensible” number of OSGi bundles was fairly significant. We had a global development team spread across a dozen labs and nearly as many timezones, all learning OSGi principles at the same time. What could possibly go wrong? I’ll spend a little time reviewing the consequences of our bundles-first-services-later approach but our success was initially limited to having the equivalent of a well-organized and large container ship which could travel at speed but needed a pretty wide berth. Our initial investment in OSGi delivered on most of the internal benefits we wanted but failed on some of the external ones that matter to our customers.
Application Servers are used in different ways by Developers and IT Operations. Ops teams care about the overall cost, including performance and availability, of the platform and the applications it supports; Dev teams care about how quickly and easily they can create and deliver their applications and treat the server as a tool. Only some of them know or care about OSGi; multi-channel enablement and cloud deployment are the current pressures they are under. Today, WebSphere is a consumer of OSGi in two distinct fashions. Internally we learned from our earlier experiences and embraced an OSGi services model to enable us to run the same runtime just as fast but in a far more dynamic fashion: it’s how we can start/stop individual technologies of the Java EE Web Profile independently on the WAS Liberty profile, in a 50MB install with a 2-second startup while still support all our customers’ existing deployments. Externally we support both Enterprise OSGi and traditional Java EE as application programming models, on the same runtime and using the same Eclipse-based tools. Our customers who understand and care about OSGi can develop and deploy web application bundles and multi-bundle enterprise applications. Those who don’t care about OSGi benefit from it ind
Structuring software systems with OSGi - Ulf Fildebrandtmfrancis
OSGi is providing a module system, but during implementation in projects it becomes difficult to really use the benefits of an OSGi runtime. Without follow the principles an OSGi system can evolve to a tightly-coupled system like in the past. Some principles and guidelines have to be followed to achieve a good architecture of a software system: - interface/implementation separation for bundles - visibility usage of bundles (import/export) - extensibility for services (and special focus on declarative services) - layering of bundles and using declarative service for layer communication - mocking of layers to achieve maturity of the implementation - interface evolution of bundles to achieve extensibility The presentation will show the changes by refactoring a small web application. The application starts as a tightly coupled system and will be improved by applying the architecture principles. So, in the presentation a lot of coding will be shown, until a good structure of the application is achieved. The guidelines are based on experiences in different projects and are used as best practices in new projects.
This is an overview how to build an OSGI EJB3 Server I gave at OSGIExpertsDay at JAX09.
The Server is build using:
Eclipse Equinox as OSGI Framework
Eclipse Riena for Remote OSGI Services
EasyBeans as OSGI EJB3 Container
Hibernate as JPA Provider
Clients are Rich Clients (Eclipse RCP)
The project is model-driven using UML (MagicDraw), EMF (Eclipse Modeling) and oAW (openArchitectureWare).

OSGi & Java EE: A hybrid approach to Enterprise Java Application Development,...OpenBlend society
There's a considerable activity in the enterprise Java community about the use of OSGi in Java EE applications. We call such applications "hybrid applications." With hybrid applications, developers can continue to build standard and familiar enterprise application components, such as Java Servlets and EJBs, and take full advantage of:
* Features such as modularity/dependency management, service dynamism, and more provided by OSGi
* Infrastructure services such as transaction management, security, persistence, and more offered by Java EE
This session will present the current state of affairs, discuss the benefits of hybrid applications, and demonstrate development and deployment of such applications.
GlassFish will be used for demonstration.

Towards a modularity maturity model - osgi users forum uk 16-nov2011mfrancis
Presentation by Graham Charters at OSGi Users' Forum UK meeting on Nov 16, 2011 in London.
Abstract: For those in the thick of OSGi, it is easy to forget what it was like to get started, and what benefits are achieved at each stage. Drawing inspiration from the various SOA maturity models, I thought it would be an interesting exercise to try to put together a modularity equivalent, and so the Modularity Maturity Model (M3) was born. The title says "Towards" because this is an initial proposal and so input from the audience (rocks, rotten vegetables, and maybe even faint praise) would be welcome.

Best Practices for (Enterprise) OSGi applications - Tim Wardmfrancis
OSGi DevCon 2012
Since the first release of the OSGi Enterprise specification in March 2010 the use of OSGi in the enterprise has increased dramatically. Moving traditional Java EE applications to an OSGi stack is intentionally as easy as possible, however there are a number of common mistakes that can make it feel very hard. This session will describe some best practices for developing Enterprise OSGi applications and OSGi bundles, allowing developers to utilise the power of OSGi in a painless way.
Whilst this session is primarily aimed at enterprise developers new to OSGi, much of the content is equally applicable to OSGi development in general, and is definitely recommended to anyone looking to brush up on their OSGi principles!

What's happening in the OSGi IoT Expert Group? - Tim Wardmfrancis
OSGi Community Event 2015
The IoT Expert Group is the newest Expert Group in the OSGi Alliance, but what exactly is an Expert Group, and what does it do? What does that mean for OSGi as an IoT platform?</p>
This talk from the chair of the IoT Expert Group will cover the progress of the IoT Expert Group since its creation in July, what outputs we can expect to see in the future, and also information about how you can get involved with the Expert Group.
The OSGi service platform has existed as a modular micro-service runtime for well over a decade, and it was originally created to run on small embedded systems in the home. It turns out that the same model works very well on servers and in the cloud, making OSGi the perfect platform for end-to-end IoT development.
In the last twelve months the OSGi Alliance have been on an IoT requirements gathering mission, the result of which has been the new IoT Expert Group. Fresh from their first official meeting in Turin the IoT Expert Group is now ready to start the process of building new standards within the Alliance. If you're interested in getting involved, or just curious about what's going on, then come along to find out more.

Virgo is a completely modular OSGi based, standards compliant, Java enterprise application server. Learn about the new standards we are supporting and the new 'Region' based scoping mechanism from Equinox. A look at how to Snap up the front end of your web apps. Demos will show Virgo, our tooling support and all the new features in 3.0.
Getting started with OSGi using a 3D OSGi Robot sample application - Christia...mfrancis
OSGi requires additional expertise from Java developers. During the first OSGi Code Camp (OCC) [1] organized by OSGi Users’ Forum Germany [2], we tried to bring OSGi beginners and experts together, to learn the core concepts and ideas behind OSGi. There will be a 2nd OSGi Code Camp held on 1st of October in Berlin extending the idea of a software craftsmanship training for OSGi beginners and experts. The first part of the talk describes the agile method we used to teach OSGi core concepts by developing an OSGi demo application in pair-programming mode. In the second part of the talk we will explain how we intend to advance the code camp approach by providing a running example - a Robot running on OSGi [3]. The core OSGi concepts will be demonstrated and teached through extensions to the prepared sample application, developed by the Code Camp participants. The extensions are developed in pairs with one OSGi expert and a beginner. The final part of the talk shows the running interactive 3D robot demo application, and explains which OSGi concepts we think should be added during the next code camp.

Keynote: OSGi Past, Present and Future - Alex Blewittmfrancis
OSGi has been around for over a decade, although its big popularity boost occurred when it became the runtime platform for Eclipse 3.0 in 2004. Since then, it has gone through four core specification revisions and become the de-facto runtime for Enterprise Java application servers.
This talk will look back at how far we've come, what is just around the corner, and a peer into the future of users of the OSGi platform.

OSGi DevCon 2008
OSGi is a mature and well received technology. It is the component model and module system underpinning Eclipse. But what is next for OSGi? This short talk will take a quick look at some of the proposed changes for the next release of the OSGi technology.
Subsystems: For those occasions where bundles are just too small... - Graham ...mfrancis
Enterprise OSGi 4.2 standardized the use of a number of component models for developing Enterprise OSGi applications: Servlet, JSP, Blueprint, and JPA. Implementations of these specifications have since become available in many open source projects and products such as Apache Aries, Eclipse Gemini/Virgo, GlassFish, JBoss Application Server and WebSphere Application Server. Looking at a number of these environments, it's clear that when it comes to assembly and deployment there's still something missing, namely something to represent a collection of bundles (e.g. an Application). Eclipse Virgo has "PARs" and "Plans", Apache Aries has "Applications", and WebSphere Application Server has “Applications” and “Composites”. Looking further afield to kernel projects, other bundle collection concepts exist, such as Apache Karaf "Features". Each model has concepts in common, such as identity, versioning and content, but also differences like isolation and format. It is clear that this is an area of Enterprise OSGi that could benefit from standardization and hence the Subsystems specification is being created. Subsystems is currently a draft specification which is standardizing artefacts representing collections of bundles, such as an Application. This presentation will introduce the current Subsystems design. It will describe how Subsystems can be used for development and deployment of bundle collections with different isolation semantics, to address the application, composite and feature use cases seen in the OSGi community today.

Eclipse Modeling Framework and plain OSGi the easy way - Mark Hoffman (Data I...mfrancis
OSGi Community Event 2018 Presentation by Mark Hoffmann (Data In Motion)
Abstract: This talk will show you how the EMF framework can be used in pure OSGi environments other than Equinox. We will introduce you into free configurable ResourceSets and the principle of a ResourceSetFactory. This enables your application to have multiple tenants with different model visibillity. The profit of OSGi services provides a behavior where even models can come and go all the time.
We will also give you look inside, how easy it is to extend the default code generation process of EMF to generate OSGi service component that handle the model registration in an OSGi way.
OSGi Community Event 2018 Presentation by BJ Hargrave (IBM)
Abstract: Java 9 introduced the Java Platform Module System (JPMS) as a way to modularize the Java platform and it can be also be used by developers to modularize their own applications, although JPMS lack a number of important features for software running on the Java platform.
As people look to support the latest versions of the Java platform, changes introduced in Java 9 related to JPMS led to the needs for some features in the OSGi Core specification. OSGi framework implementations like Eclipse Equinox and Apache Felix and tools like Bnd were updated to support these new features.
This session will explore the Java 9+ support added to OSGi Core R7 and Bnd and help you learn how to navigate the world of Java 9+ and OSGi.

OSGi Community Event 2018 Presentation by Paul Fraser (A2Z Living)
Abstract: This talk will demonstrate how easy it is to create great web user interfaces using the OSGi Service registry and Declarative Services.
OSGi has developed to the point that much can be achieved with much reduced code complexity. Forget all the past OSGi techniques and see how it can be done now.
A short introduction will introduce OSGi in general and even if beginners do not fully understand the finer details of the talk, they will be amazed at what can be achieved using the OSGi service registry.
Do not be frightened by the terminology, come along and experience the magic of OSGi modularity.
User interfaces do not seem to get much attention in the OSGi community, it is time for a change.
OSGi for the data centre - Connecting OSGi to Kubernetes - Frank Lyaruumfrancis
OSGi Community Event 2018 Presentation by Frank Lyaruu
Abstract: OSGi offers an excellent service discovery mechanism, it is limited to services inside the JVM. That limits us in two ways: It limits us to Java services, and it limits us to one single machine, and neither are acceptable in this day and age. Can we connect our OSGi runtime to a cluster orchestration manager like Kubernetes so our runtime can interact with the cluster and allow us to respond to changes in the cluster as dynamically as we are used to in OSGi itself. I think we can.
Notes:
I will show how to discover Kubernetes services (and their pods) in a cluster, and inject those as configuration objects into an OSGi runtime. That allows us to monitor the Kubernetes cluster and dynamically have our OSGi services respond to (Kubernetes) service changes.
In general I hope to nudge the OSGi community to be more focused on connecting to other technologies rather than trying to stay in the OSGi walled garden. A well engineered OSGi application is perfectly suited to the dynamic nature of the cloud native world, but if we can't easily integrate with other services, well, nobody will care.
Remote Management and Monitoring of Distributed OSGi Applications - Tim Verbe...mfrancis
OSGi Community Event 2018 Presentation by Tim Verbelen (imec) & Jan S. Rellermeyer (TU Delft)
Abstract: With the proliferation of cloud computing and more recently mobile and edge computing, there is a increasing demand to build flexible and robust distributed applications. The OSGi service and module technology is a key enabler for such deployment. Recent additions to the OSGi standards provide a set of services that provide interfaces for managing distributed instances of OSGi frameworks. The REST Service (added in R6 compendium) offers an easy and language-independent way to manage bundes and introspect services from outside the network. The Cluster Information specifications (added in R7 compendium) provide means for applications to manage and monitor the deployment intrinsically, building on top of the Remote Service specifications. In the Eclipse Concierge project, we have provided the reference implementations of both specifications. In this talk, we will show how the services can be used to build distributed applications that benefit from the OSGi modularity.
OSGi with Docker - a powerful way to develop Java systems - Udo Hafermann (So...mfrancis
OSGi Community Event 2018 Presentation by Udo Hafermann (Software AG)
Abstract: In this talk we will share our experiences in developing a tool chain from classes, to bundles, to containers, to systems.
OSGi and Docker come together in a compelling way where the former provides modularity "in the small" and the latter "modularity in the large". We discover how the unique characteristics of OSGi enable a smooth transition from small to large.
The resulting environment enables developers to grow distributed systems on their local machine and test them with plain JUnit at all levels of granularity - classes to systems. During development OSGi enables the tool chain to update the system without container rebuilds.
While an increase in productivity is one benefit of such an environment, an arguably more important benefit is the way it empowers developers to gain new insights.
A real world use case with OSGi R7 - Jurgen Albert (Data In Motion Consulting...mfrancis
OSGi Community Event 2018 Presentation by Jurgen Albert (Data In Motion Consulting GmbH)
Abstract: OSGi is often conceived as a tool to write efficient Java Applications for resource limited Devices or If resources are a real issue in complex applications. On the other hand Microservices became the buzzword of the cloud and is often implemented using Spring or other Programming languages. OSGi carries the concept of microservices in its core and is therefore much better suited to the task then most other approaches. This talk will show you how a service can be built with a real-worldish use case, leveraging the power of OSGi R7. It will show the combined usage of PushsStreams, the JaxRS Whiteboard, the configurator, remote deployment and a lot of the other cool things OSGi has to offer.
OSGi Feature Model - Where Art Thou - David Bosschaert (Adobe)mfrancis
OSGi Community Event 2018 Presentation by David Bosschaert (Adobe)
Abstract: OSGi lends itself well to develop extensible applications assembled from reusable modules, where a set of bundles together with a set of configurations deployed to a provisioned OSGi framework is the application.
While this works very well for the originally intended use-cases, maintaining and building large applications developed by multiple teams often requires to assemble multiple larger components for which there is limited support in OSGi as of today. This is especially true in cases where multiple groups of bundles, configuration, metadata, and other artifacts need to be combined.
In this talk we will introduce you to OSGi RFP-188, named OSGi Features, which defines the requirements on providing a solution. We'll establish a shared understanding of the problem space and how it relates to already available mechanisms in OSGi (like e.g. subsystems, deploymentadmin, startlevels, etc.) and will subsequently, review it in the context of some of the current (open source) solutions like Apache Karaf Features and Apache Sling Features and Bnd.
Migrating from PDE to Bndtools in Practice - Amit Kumar Mondal (Deutsche Tele...mfrancis
OSGi Community Event 2018 Presentation by Amit Kumar Mondal (Deutsche Telekom AG) & Jochen Hiller (Deutsche Telekom AG)
Abstract: QIVICON is an Eclipse SmartHome based solution from Deutsche Telekom AG. It utilises OSGi to provide a modular Java runtime.
Since the beginning, QIVICON leveraged Eclipse PDE with Maven & Eclipse Tycho as its build technology but over the time, the complexity increased. It became hard to get an overview and manage the runtime and build dependencies. Especially maintaining target configurations for IDE and CI/CD build, having different embedded gateways for installation increased complexity significantly.
Bndtools is the 'swiss army knife' in the context of OSGi development since it takes the nitty-gritty pains and loads off the developer's chest. And that's why we decided to avail the benefits of Bndtools.
But, many other OSGi-based projects still cannot avail the benefits as they are very tightly coupled with Eclipse PDE. Want to make a switch from your existing PDE source base to Bndtools? This talk would give you an overview to proceed towards this.
We would like to further demonstrate in this talk how to set up a Bndtools workspace from an existing PDE workspace, convert all current projects to Bnd projects and embrace the OSGi-way of developing bundles.
Since QIVICON containing more than 350 projects utilised this solution to move to a higher modularity maturity level, this talk would, therefore, outline the pros, cons and the learnings using Bndtools in such a big OSGi project for embedded development.

How OSGi drives cross-sector energy management - Jörn Tümmler (SMA Solar Tech...mfrancis
OSGi Community Event 2018 Presentation by Jörn Tümmler (SMA Solar Technology)
Abstract: SMA is a leading global specialist in photovoltaic system technology with more than 3,000 SMA employees in 20 countries.
In 2015 SMA decided to develop the ennexOS platform - a cross-sector platform for holistic, intelligent energy management. An important part of this platform is the data-manager - an IoT gateway that acquires information from various energy generators, storages and loads and performs commissioning and management tasks.
This new generation of data-managers demanded for new approaches in software-architecture to:
run on a broad range of hardware platforms, and
be extendible e.g. to support different protocols for easy integration, and
to enable a broad range of applications in the energy-management field that may be customized by apps installed during runtime
After an exhaustive investigation on existing solutions, OSGi was chosen as the key technology for this new generation of devices - a quite challenging decision, because at this point there was only limited experience in Java and OSGi development in the company.
This talk will present the key factors that lead to this decision, how we very carefully build up Java and OSGi knowledge, and started with an initial design. OSGi enRoute and the support of OSGi experts helped us to accelerate our development and become familiar with OSGi - although we also had times when we were struggling because of the new technology.
The talk will demonstrate what we have reached until now and we will tell you if OSGi has kept it's promise ...
Improved developer productivity thanks to Maven and OSGi - Lukasz Dywicki (Co...mfrancis
OSGi Community Event 2018 Presentation by Lukasz Dywicki (Code-House)
Abstract: During this short presentation I will revisit existing mechanisms and approach towards OSGi and JEE development. I will show how many manual steps can be avoided and how to maintain project in effective manner. I will try to find a balance between execution environment requirements and programmer happines at same time.
I believe that OSGi and Eclipse ecosystem experience troubles gaining people from outside for few reasons. Beside overall impression of OSGi complexity there is equally old and invalid complain about quaility of developer tooling. Since invention of BND development experience can be really pleasant and independent of text editor/IDE preferences. Sadly lots of people still rely on former experiences spreading black/bad PR. I would like to clarify their point.
After this presentation attendees will learn:
How to use Maven to build OSGi projects (without Tycho).
How to automate manual tasks.
How to build custom software distributions with Maven artifacts and run it with Apache Karaf.
That OSGi development doesn't differ much from regular day-to-day usage of application servers or microservice runtimes.
This talk is intended for people who know basics of OSGi as it will show few basic technics towards better developer productivity.
It Was Twenty Years Ago Today - Building an OSGi based Smart Home System - Ch...mfrancis
OSGi Community Event 2018 Presentation by Christer Larsson (Makewave)
Abstract: OSGi was originally designed for Smart Homes and Residential Gateways almost 20 years ago.
This talk will present how the OSGi specifications have evolved over the years, and how you today, in 2018, design an OSGi based Smart Home System.
A real world use case of a Swedish Smart Home start-up company will be used to illustrate different design principles and how OSGi remains as relevant today as it was when it started.
Popular patterns revisited on OSGi - Christian Schneider (Adobe)mfrancis
OSGi Community Event 2018 Presentation by Christian Schneider (Adobe)
Abstract: We will look at common cloud and design patterns and see how the special properties of the OSGi environment allows us to rethink these patterns. The talk shows some well known patterns like the service registry and the whiteboard but also some unique patterns like out of band circuit breaker or graceful degregation.
The patterns are shown with some examples using declarative services(DS). So some basic OSGi and DS knowledge is of advantage but not required.
For OSGi beginners the well established OSGi patterns will help getting started the right way. Experienced OSGi developers will find some new patterns to think about. Cloud or enterprise developers will get a new approach to some patterns they are used to which hopefully inspires them to take another look at the current state of OSGi.
Integrating SLF4J and the new OSGi LogService 1.4 - BJ Hargrave (IBM)mfrancis
OSGi Community Event 2018 Presentation by BJ Hargrave (IBM)
Abstract: OSGi Compendium R7 provides a major update to the OSGi LogService specification. A new logging API is added which supports logging levels and dynamic logging administration. A new Push Stream-based means of receiving log entries is also added. But it is quite often the case you need to use other code such as open source projects which are using slf4j for their logging API. This session will explore the new OSGi LogService changes and how you can integrate code using both slf4j logging and OSGi LogService logging.
OSG(a)i: because AI needs a runtime - Tim Verbelen (imec)mfrancis
OSGi Community Event 2018 Presentation by Tim Verbelen (imec)
Abstract: Nowadays AI is reaching new heights on the hype cycle, especially due to recent advances in deep learning techniques. A lot of deep learning frameworks exist for creating and training deep neural networks, the most popular ones being PyTorch and TensorFlow. However, how to integrate, deploy and manage these neural networks in complex software systems is often overlooked. In this talk we show how OSGi can be used as a modular runtime for deep learning models. We embed those models inside OSGi bundles, and use the extender pattern to make these available as OSGi services. You can then use your favorite OSGi specs such as DS and PushStreams to integrate these into your application.
Flying to Jupiter with OSGi - Tony Walsh (ESA) & Hristo Indzhov (Telespazio V...mfrancis
OSGi Community Event 2018 Presentation by Tony Walsh (ESA) & Hristo Indzhov (Telespazio Vega)
Abstract: The European Space Operations Centre (ESOC) is the main operations center for the European Space Agency (ESA), operating a number of earth observation and scientific missions. Monitoring and control functions needed by spacecraft operators are provided by software systems which are reused across missions, but tailored and extended for mission specific needs. The current generation of monitoring and control systems are becoming obsolete and a European wide initiative called the European Ground Systems Common Core (EGS-CC) (http://www.egscc.esa.int) has been started to develop the next generation.
This talk will explain why OSGi was chosen and how it is used in the development of next generation of monitoring and control software. It will describe how OSGi provides the necessary framework that enables the software to be extended for the different space systems it is expected to support. The overall software architecture will be discussed, some of the challenges faced and the benefits gained by using OSGi. The first target mission for the system is JUICE (http://sci.esa.int/juice) which will explore the moons of Jupiter and which is scheduled for launch in 2022.
MicroProfile, OSGi was meant for this - Ray Auge (Liferay)mfrancis
OSGi Community Event 2018 Presentation by Ray Augé (Liferay)
Abstract: The craze is fully on. The past couple of years have seem micro services grow from next _flava_ to fully consuming of the software industry. The Eclipse micorprofile.io project is tackling the issue putting common usage patterns together over a foundation of CDI. What better assembly driver is there than OSGi to put it all together. This talk will demonstrate building your own MicroProfile using OSGi and the OSGi enRoute packaging model.
Prototyping IoT systems with a hybrid OSGi & Node-RED platform - Bruce Jackso...mfrancis
OSGi Community Event 2018 Presentation by Bruce Jackson (Myriad)
Abstract: Node-RED is often used as a protyping tool for IoT systems. However, there are also a large number of OSGi components that have already been built to interface to devices, sensors and systems. In this talk I will show how two completely different runtime environments (OSGi and Node-RED) can be combined into a single platform for prototyping (and more) combining the strengths of both languages and systems.
Being able to quickly and simply prototype IoT application is extremely useful, and to this end many people have adopted Node-Red, a Node.js based runtime with extensive support for plugins to interface to various IoT hardware and protocols. However, this requires these services/protocols to be developed in Javascript, and there is already a significant body of code developed in Java/OSGi that it would be desirable to re-use.
The talk will explain how it is possible to:
Create and manage a Node-Red runtime from within an OSGi bundle
Share OSGi components and object into the Node-Red runtime
Interact and build Node-Red flows that exchange data and call methods between Node.js and OSGi
This is obviously useful for the original purpose: prototyping IoT systems, but also demonstrates some interesting techniques for bridging between different languages and runtimes.
How to connect your OSGi application - Dirk Fauth (Bosch)mfrancis
OSGi Community Event 2018 Presentation by Dirk Fauth (Bosch)
Abstract: In todays connected world the requirement to connect applications across network boundaries has become a common requirement. With OSGi there are several ways to accomplish this, as there are different specifications to achieve this. In this talk we will look at some of these specifications to show what options there are and which might fit your requirements. Starting from an architecture that makes use of the HTTP Whiteboard pattern, over Remote Services to finally showing the usage of the JAX-RS Whiteboard specification introduced with R7. We will show the general usage of these specifications and explaining the advantages and disadvantages of each solution.

Unveiling the Secrets How Does Generative AI Work.pdfSam H
At its core, generative artificial intelligence relies on the concept of generative models, which serve as engines that churn out entirely new data resembling their training data. It is like a sculptor who has studied so many forms found in nature and then uses this knowledge to create sculptures from his imagination that have never been seen before anywhere else. If taken to cyberspace, gans work almost the same way.

Memorandum Of Association Constitution of Company.pptseri bangash
www.seribangash.com
A Memorandum of Association (MOA) is a legal document that outlines the fundamental principles and objectives upon which a company operates. It serves as the company's charter or constitution and defines the scope of its activities. Here's a detailed note on the MOA:
Contents of Memorandum of Association:
Name Clause: This clause states the name of the company, which should end with words like "Limited" or "Ltd." for a public limited company and "Private Limited" or "Pvt. Ltd." for a private limited company.
https://seribangash.com/article-of-association-is-legal-doc-of-company/
Registered Office Clause: It specifies the location where the company's registered office is situated. This office is where all official communications and notices are sent.
Objective Clause: This clause delineates the main objectives for which the company is formed. It's important to define these objectives clearly, as the company cannot undertake activities beyond those mentioned in this clause.
www.seribangash.com
Liability Clause: It outlines the extent of liability of the company's members. In the case of companies limited by shares, the liability of members is limited to the amount unpaid on their shares. For companies limited by guarantee, members' liability is limited to the amount they undertake to contribute if the company is wound up.
https://seribangash.com/promotors-is-person-conceived-formation-company/
Capital Clause: This clause specifies the authorized capital of the company, i.e., the maximum amount of share capital the company is authorized to issue. It also mentions the division of this capital into shares and their respective nominal value.
Association Clause: It simply states that the subscribers wish to form a company and agree to become members of it, in accordance with the terms of the MOA.
Importance of Memorandum of Association:
Legal Requirement: The MOA is a legal requirement for the formation of a company. It must be filed with the Registrar of Companies during the incorporation process.
Constitutional Document: It serves as the company's constitutional document, defining its scope, powers, and limitations.
Protection of Members: It protects the interests of the company's members by clearly defining the objectives and limiting their liability.
External Communication: It provides clarity to external parties, such as investors, creditors, and regulatory authorities, regarding the company's objectives and powers.
https://seribangash.com/difference-public-and-private-company-law/
Binding Authority: The company and its members are bound by the provisions of the MOA. Any action taken beyond its scope may be considered ultra vires (beyond the powers) of the company and therefore void.
Amendment of MOA:
While the MOA lays down the company's fundamental principles, it is not entirely immutable. It can be amended, but only under specific circumstances and in compliance with legal procedures. Amendments typically require shareholder
