OSGi ecosystems compared on Apache Karaf - Christian Schneidermfrancis
OSGi Community Event 2015
A look at three competing OSGi ecosystems (Declarative Services, Blueprint, CDI). Capabilities of each DI framework. Comparison of support for EE technologies like JPA, Security, SOAP and REST services, UIs. Looking into some of the recent advancements like Aries JPA 2 featuring closure based transactions, JAAS Security, JSP and JSF on OSGi. Attendees will get a good overview about the stacks as well as recommendations where each is most applicable.
When building and maintaining large applications in a world that is rapidly evolving, keeping up with changing requirements and non-functionals over time is a huge challenge. Architecting your application in a modular way and loosely coupling modules using micro services provides you with a nicely decoupled system that still works very efficiently. Designing, evolving and versioning a micro service architecture is not easy, and over time, several design patterns and best practices have evolved that help you.

Have you ever thought that your Lambda functions could fail without you even noticing?
If the answer is YES, that’s probably because you already “burnt" yourself playing with the cloud, where errors and failures are always around the corner…
Unfortunately we can’t prevent all types of failures, but what we can do is try to spot them as soon as possible and react quickly.
In order to do that, we need good observability for our serverless applications and therefore we need to become good friends with services like CloudWatch.
If you have tried CloudWatch already, you probably know how powerful but also complex it can be…
In this talk we will approach the topic of observability for serverless applications on AWS. We will discuss best practices and how to build a good friendship with CloudWatch.
We will also present some interesting automation tools that we can use to take away most of the pain of setting up dashboards and alarms in CloudWatch, making it easier to achieve great levels of observability.

Moving From Actions & Behaviors to MicroservicesJeff Potts
My DevCon 2019 talk discusses how to make it easier to integrate Alfresco with other systems using an event-based approach. Two real world examples are discussed and demonstrated. The first is about reporting against Alfresco metadata. The second is about enriching metadata by running content through a Natural Language Processing (NLP) model. Both solutions work by listening to generic events generated by Alfresco and placed on an Apache Kafka queue. For the reporting example, the Spring Boot consumer subscribes to Kafka events, then fetches metadata via CMIS and indexes that into Elasticsearch. For the NLP example, a separate Spring Boot consumer subscribes to the same events, but in this case, fetches the content, extracts text using Apache Tika, runs the text through Apache OpenNLP, then writes back extracted entities to Alfresco via CMIS. These are relatively simple examples, but illustrate how a de-coupled, asynchronous, event-based approach can make integrating Alfresco with other systems easier.
The objective of this article is to describe what to monitor in and around Alfresco in order to have a good understanding of how the applications are performing and to be aware of potential issues.
Alfresco Platform Update and Roadmap delivered by Gabriele Columbro, Senior Product Manager for Core Platform / API at Alfresco, with updates on the upcoming Alfresco 5.1 release, on Extreme Scalability (and Solr sharding), Share separation, the new API lifecycle and brand new Developer documentation, samples and tutorials. Mentions of the Upgrade Task Force and new Developer platform improvements like support for JAR modules and tracking / reporting of Share modules.

WEB: http://J10.IndicThreads.com
------------
Java Platform, Enterprise Edition 6 (JavaEE 6) provides new capabilities that make it easier to develop and deploy enterprise and Web applications. It provides a simplified developer experience and improves on the developer productivity features introduced in JavaEE 5. It breaks the “one size fits all” approach in previous releases with Profiles and offers a comprehensive Web profile for lightweight, standards-based modern Web applications.The Web profile allows developers to build web applications quickly and prevents proliferation of custom web stacks for easier maintainability.
The platform enables extensibility by embracing open source libraries and frameworks such that they are treated as first class citizens of the platform. Several specifications like Contexts & Dependency Injection, Java Server Faces 2, Java API for RESTful Services, Java Persistence API 2, and Servlets 3 make the platform more powerful. All these specifications are implemented in GlassFish Open Source Edition 3 – a modular (OSGi based) light-weight, embeddable, extensible, and the open source reference implementation for Java EE 6. NetBeans, Eclipse, and IntelliJ provide extensive tooling for Java EE 6 and GlassFish Open Source Edition.
This tutorial session will help the attendees learn the latest APIs and develop a complete Java EE 6 application using NetBeans IDE. The attendees will understand the different tips & tricks such as code completion, templates, and wizards for a rapid application deployment. The techniques like session preservation and deploy-on-save are demonstrated to reduce the development lifecycle.

Running Kafka as a Native Binary Using GraalVM with Ozan GünalpHostedbyConfluent
"During development and automated tests, it is common to create Kafka clusters from scratch and run workloads against those short-lived clusters. Starting a Kafka broker typically takes several seconds, and those seconds add up to precious time and resources.
How about spinning up a Kafka broker in less than 0.2 seconds with less memory overhead? In this session, we will talk about kafka-native, which leverages GraalVM native image for compiling Kafka broker to native executable using Quarkus framework. After going through some implementation details, we will focus on how it can be used in a Docker container with Testcontainers to speed up integration testing of Kafka applications. We will finally discuss some current caveats and future opportunities of a native-compiled Kafka for cloud-native production clusters."

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.

An Approach to Detecting Writing Styles Based on Clustering Techniquesambekarshweta25
An Approach to Detecting Writing Styles Based on Clustering Techniques
Authors:
-Devkinandan Jagtap
-Shweta Ambekar
-Harshit Singh
-Nakul Sharma (Assistant Professor)
Institution:
VIIT Pune, India
Abstract:
This paper proposes a system to differentiate between human-generated and AI-generated texts using stylometric analysis. The system analyzes text files and classifies writing styles by employing various clustering algorithms, such as k-means, k-means++, hierarchical, and DBSCAN. The effectiveness of these algorithms is measured using silhouette scores. The system successfully identifies distinct writing styles within documents, demonstrating its potential for plagiarism detection.
Introduction:
Stylometry, the study of linguistic and structural features in texts, is used for tasks like plagiarism detection, genre separation, and author verification. This paper leverages stylometric analysis to identify different writing styles and improve plagiarism detection methods.
Methodology:
The system includes data collection, preprocessing, feature extraction, dimensional reduction, machine learning models for clustering, and performance comparison using silhouette scores. Feature extraction focuses on lexical features, vocabulary richness, and readability scores. The study uses a small dataset of texts from various authors and employs algorithms like k-means, k-means++, hierarchical clustering, and DBSCAN for clustering.
Results:
Experiments show that the system effectively identifies writing styles, with silhouette scores indicating reasonable to strong clustering when k=2. As the number of clusters increases, the silhouette scores decrease, indicating a drop in accuracy. K-means and k-means++ perform similarly, while hierarchical clustering is less optimized.
Conclusion and Future Work:
The system works well for distinguishing writing styles with two clusters but becomes less accurate as the number of clusters increases. Future research could focus on adding more parameters and optimizing the methodology to improve accuracy with higher cluster values. This system can enhance existing plagiarism detection tools, especially in academic settings.

94. JEE with Karaf?
• Adoptions needed? YES
• Minor on Persistence - JNDI lookup
• Minor on transaction - Blueprint JTA
• Wiring of Services:
• Use Blueprint
• Use Servlet 3.0 with CDI - @OsgiService
• Session Replication throughout cluster, it’s still standard
