EWD 3 Training Course Part 36: Accessing REST and Web Services from a QEWD ap...Rob Tweed
This document describes how to create a REST proxy using QEWD. It involves:
1. Amending the backend restDemo.js module to extract the REST call logic into a separate function and define a 'proxy' handler function.
2. Setting the module to be a REST module.
3. Having the proxy handler function invoke the extracted REST call logic to proxy requests to the actual REST service.
4. Adding a route in the QEWD startup file to route the /api/proxy URL to the proxy handler function, exposing the REST service via the proxy.
This allows the module to act as a REST proxy to the external JSONPlaceholder service while still supporting normal interactive apps

Examples and demos are provided to illustrate concepts like creating custom widgets, handling events, and making asynchronous server calls. Resources for learning more about GWT are also listed.
This is a presentation I gave in Helsinki Node.js meetup (check http://helnode.io).
I have been implementing a realtime communication service with Ruby during my previous assignment. I've used Rails and lower level Ruby frameworks such as Sinatra and Resque workers.
I do like especially the Rack, since it enables building an efficient server stack. You can throw in middleware for throttling, authentication and for other tasks quite easily.
Ruby was a strong candidate also for my current project. I consider the Ruby code is more readable than JavaScript. However, once I understood what ECMAScript 6 brings in, I was sold to Node.js. Generators will enable actually very similar implementations than the Ruby's Rack stack. In my opinion, JavaScript will finally become mature with JS1.7 as the "callback spaghetti" will be soon history."

LNUG: Having Your Node.js Cake and Eating It TooRob Tweed
The document discusses using Node.js for server-side applications. It introduces QEWD, a Node.js platform that allows running code in isolated worker processes to avoid Node.js's concurrency issues. QEWD uses a master process to queue incoming requests and dispatch them to separate worker processes. This allows Node.js code to leverage synchronous logic and avoid CPU-intensive tasks blocking other requests. The document argues this allows developers to "have their Node.js cake and eat it" by using Node.js for all application needs.

Why Apache Kafka Clusters Are Like Galaxies (And Other Cosmic Kafka Quandarie...Paul Brebner
Closing talk for the Performance Engineering track at Community Over Code EU (Bratislava, Slovakia, June 5 2024) https://eu.communityovercode.org/sessions/2024/why-apache-kafka-clusters-are-like-galaxies-and-other-cosmic-kafka-quandaries-explored/ Instaclustr (now part of NetApp) manages 100s of Apache Kafka clusters of many different sizes, for a variety of use cases and customers. For the last 7 years I’ve been focused outwardly on exploring Kafka application development challenges, but recently I decided to look inward and see what I could discover about the performance, scalability and resource characteristics of the Kafka clusters themselves. Using a suite of Performance Engineering techniques, I will reveal some surprising discoveries about cosmic Kafka mysteries in our data centres, related to: cluster sizes and distribution (using Zipf’s Law), horizontal vs. vertical scalability, and predicting Kafka performance using metrics, modelling and regression techniques. These insights are relevant to Kafka developers and operators.

Penify - Let AI do the Documentation, you write the Code.KrishnaveniMohan1
Penify automates the software documentation process for Git repositories. Every time a code modification is merged into "main", Penify uses a Large Language Model to generate documentation for the updated code. This automation covers multiple documentation layers, including InCode Documentation, API Documentation, Architectural Documentation, and PR documentation, each designed to improve different aspects of the development process. By taking over the entire documentation process, Penify tackles the common problem of documentation becoming outdated as the code evolves.

Superpower Your Apache Kafka Applications Development with Complementary Open...Paul Brebner
Kafka Summit talk (Bangalore, India, May 2, 2024, https://events.bizzabo.com/573863/agenda/session/1300469 )
Many Apache Kafka use cases take advantage of Kafka’s ability to integrate multiple heterogeneous systems for stream processing and real-time machine learning scenarios. But Kafka also exists in a rich ecosystem of related but complementary stream processing technologies and tools, particularly from the open-source community. In this talk, we’ll take you on a tour of a selection of complementary tools that can make Kafka even more powerful. We’ll focus on tools for stream processing and querying, streaming machine learning, stream visibility and observation, stream meta-data, stream visualisation, stream development including testing and the use of Generative AI and LLMs, and stream performance and scalability. By the end you will have a good idea of the types of Kafka “superhero” tools that exist, which are my favourites (and what superpowers they have), and how they combine to save your Kafka applications development universe from swamploads of data stagnation monsters!
