Aglets is a Java-based framework that allows programmers to create mobile software agents. The Aglets API provides functionality for agent creation, movement between systems, communication via message passing, and more. Potential applications of mobile agents created with Aglets include network management, distributed database access, auctions, and online shopping. The framework handles agent transport and ensures platform independence so agents can move freely across systems written in Java.

Virtualization is a new method regarding using computing resources efficiently, by maximizing energy efficiency, extend the life of the hardware and also recycles. Virtualization technology is a system of work done by the software can merge some real physical systems into a single virtual form commonly known as virtualization without prejudice advantages over the single system. Of course, this system can reduce the amount of hardware, electrical energy consumption and time used thereby increasing the level of efficiency and effectiveness. Also, virtualization certainly reduces heat energy arising from the number of installed hardware, thereby reducing the increase in temperature geothermal (Global Warming). Some virtualization includes Server Virtualization, Network Virtualization, Memory Virtualization, Grid Computing, Application Virtualization, Storage Virtualization, Virtualization and Thin Client Platform.

During the talk, we will build a simple web app using Lift and then introduce Akka ( http://akkasource.org) to help scale it. Specifically, we will demonstrate Remote Actors, "Let it crash" fail over, and Dispatcher. Other Scala oriented tools we will use include sbt and ENSIME mode for emacs.
GPars (Groovy Parallel Systems) is an open-source concurrency and parallelism library for Java and Groovy that gives you a number of high-level abstractions for writing concurrent and parallel code in Groovy (map/reduce, fork/join, asynchronous closures, actors, agents, dataflow concurrency and other concepts), which can make your Java and Groovy code concurrent and/or parallel with little effort.
Nowadays Akka is a popular choice for building distributed systems - there are a lot of case studies and successful examples in the industry.
But it still can be hard to switch to actor-based systems, because most of the tutorials and documentation don't show the way to assemble a real application using actors, especially in microservices environment.
Actor is a powerful abstraction in the message-driven environments, but it can be challenging to use familiar patterns and methodologies. At the same time, message-driven nature of actors is the biggest advantage that can be used for Reactive systems and microservices.
I want to share my experience and show how Domain-Driven Design and Enterprise Integration Patterns can be leveraged to design and build fine-grained microservices with synchronous and asynchronous communication. I'll focus on the core Akka functionality, but also explain how advanced features like Akka Persistence and Akka Cluster Sharding can be used together for achieving incredible results.
(Given to the Vancouver Erlang Meetup group on January 19, 2010.)
Wondering how to model things in Erlang, and what the Actor model is all about? This talk will cover the best of Erlang OTP, delve into using gen_server to model systems in Erlang, and demonstrate the use of supervisor trees to ensure your application stays alive and well. Those new to Erlang might want to look over an intro first, but should still gleam some insights from this talk either way.
Speaker Bio:
Ken Pratt has been working with Erlang full time since the beginning of 2009, which makes him slightly less of an Erlang noob than he was previously. Ken holds a B.Sc. in Computer Science from UBC, and is currently hard at work developing a social networking game at Pug Pharm Productions.

Learn the secrets of writing "faster than possible" GWT code, how to use Generators and Linkers in harmony, and make seamless procedure calls from GWT code to other environments like Flash, Gears, or Android.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
