Understanding Meteor Stack
2 likes475 views
The document discusses the key components that make up the Meteor stack, including Blaze, Tracker, DDP, and Mongo. It notes that while Meteor uses these components by default, the framework is customizable - developers can replace the UI library, database, and DDP client/server with alternatives. The standard Meteor application architecture is then outlined, explaining how each component fits together and interacts to provide reactivity on the client.

Meteor Taipei 2016 January talk -- Mantra
Meteor Taipei 2016 January talk -- MantraWey-Han Liaw
?
Mantra is an application architecture specification and set of libraries for building Meteor apps. It is based on Flux principles and includes core components like React UI components, action handlers for business logic, state managers for local and remote data, and container components to connect UI, actions and states. While Mantra provides a good architecture, the author believes it could be improved by being tailored more specifically for Meteor, enhancing unit testing support, and developing a code generation tool or opinionated framework to implement the pattern.java.util.concurrent for Distributed Coordination, Riga DevDays 2019
java.util.concurrent for Distributed Coordination, Riga DevDays 2019Ensar Basri Kahveci
?
The evolution of distributed coordination tools shows that high-level APIs ease implementation of coordination tasks, such as leader election, locking, synchronized actions. For instance, the Chubby paper highlights familiarity of lock-based interfaces. Similarly, Apache Curator hides complexity of ZooKeeper recipes behind Java APIs, while etcd and Consul implement concurrency primitives on their own.
A different path in this journey would be extending the long-lasting java.util.concurrent APIs, such as Lock, Semaphore, etc. Simplicity of these APIs makes them very useful in distributed coordination use cases.
Join this talk to explore Hazelcast¡¯s brand new implementation of java.util.concurrent APIs on top of the Raft consensus algorithm. I will walk through code samples to demonstrate how Java locks, semaphores, etc. can be used in distributed environments that involve partial failures. I will also share our experience of how we coped with several challenges we faced while developing and testing our Raft implementation.Azure ML and Predictive Analytics Webinar

Akka is a toolkit for building highly concurrent, distributed, and resilient message-driven applications on the JVM based on the actor model. It provides Akka Streams, which allows expressing and running a chain of asynchronous processing steps on a sequence of elements to provide back-pressured asynchronous stream processing according to the Reactive Streams initiative standard. Akka Streams handles concurrency behind the scenes, so the user describes the processing rather than the implementation.20150511 Meteor Angular

Exploring the continuum between Cordova and React NativeSimon MacDonald
?
This document discusses the continuum between Cordova and React Native for building mobile apps. It explains that Cordova uses a web view to display HTML, CSS, and JavaScript within a native container, while React Native uses native UI components instead of web views for better performance and integration. The document advocates using React Native over Cordova because it allows writing most of the app code once with reusable components across platforms, rather than needing separate code bases, and results in a better integrated user experience than a web view. It also mentions some projects that aim to bridge React Native and web technologies.Data access

Discover how FME¡¯s powerful transformers, like the ChangeDetector, can compare and detect changes to your data, automating incremental updates to keep your data warehouse and other systems synchronized in real-time.
While many tools can achieve this, they often lack support for spatial data or require complex, time-consuming processes. With FME, you get a flexible, intuitive platform that supports all data types, making change detection simple and efficient.
Join this webinar to learn change management strategies from demos that include:
- Detecting changes in your data
- Detecting changes in spatial data
- Incremental updates and data synchronization
- and more!
With FME, change is no longer something to fear. Because no matter what type of data you have, or at what stage it is in your workflow, FME makes working with change easy.
* This is part 1 of a 2-part series on managing changing data with FME. Stay tuned for Part 2 in the weeks to follow, where we¡¯ll cover further change-detection methods like database triggers and transaction logs!NANO Antivirus Pro Crack + License Code Free 2025

Generative AI burst on to the public scene in November 2022, over ten years after Andrew Ng¡¯s Machine Learning premiered on Coursera. Java developers have long felt like second class citizens, compared to the cool Python kids. LangChain4J changes the game. Java is cool with AI now! This lecture from 30-year industry veteran Ed Burns explores why it took so long for Java developers to have access to easy-to-use AI libraries, compared to Python developers. LangChain4J is the most popular of the Java libraries, but others exist. After a brief look at the landscape, we¡¯ll take a deeper look at LangChain4J and how you use it to perform the most popular AI usage pattern: Retrieval Augmented Generation (RAG). RAG is basically a way to bring your own domain specific data to an existing AI model, and benefit from its power.
