Are you aware that Oracle is offering a FREE course entitled "JDK 8 Massive Open and Online Course: Lambdas and Streams Introduction"?
Simon Ritter, Manager of the Oracle Java Technology Evangelist team will teach it.
The dates: 14-JUL-2015 03:00:00 PM GMT End Date: 4-AUG-2015 07:00:00 PM GMT
Java SE 8 (JDK 8) introduced a fundamentally new way of programming in Java with the introduction of Lambda expressions.
Lambda provides a simple way to pass functionality as an argument to another method, such as what action should be taken when someone clicks a button, or how to sort a set of names. Lambda expressions enable you to do this, to treat functionality as a method argument, or code as data.
You may have heard about Lambda expressions, and are curious what impact it will have on you as a Java developer.
This course is designed to answer your questions and more.
Have you ever wondered what Lambda expressions are in Java?
Have you ever wanted to write parallel code in Java without worrying about threads and locking?
Have you ever wanted to process collections of data without using loops?
Have you ever wanted to do functional programming in Java?
All of these questions will be answered in this practical hands-on MOOC. This course introduces two major new changes to the Java platform: Lambda expressions and the Stream API.
Unlike a traditional instructor-led event, the course is delivered on-line.
Take this course when you want, where you want, and at your own pace.
Interact with your peers and the instructor panel through the forum.
Each week we will post a new set of course materials:
A series of short, pre-recorded videos provide the "lecture" portion of the course.
A homework project is linked to the video material, and applies what you have learned by working with Lambdas and Streams.
A graded quiz evaluates how well you have grasped the materials and the homework.
Time Comitment:
3 - 4 hours weekly
Course Completion :
Based on successfully completing the course quizzes, you will receive a course completion award, suitable for printing and framing!
Language :
English
Learn To:
Apply Lambdas to everyday problems
Convert anonymous classes to Lambda expressions
Apply the Streams API to solve problems of sorting, identifying the most and least, and reducing duplicates
Determine when to apply Lambdas (and when not to!)
Use Collectors
Improve performance with parallel streams
Debug Lambda expressions

Just signed up. Thanks for the heads up.
I'm enrolled! The enroll link provided in this post did not work for me. The link provided on the YouTube page did work for me. https://www.youtube.com/watch?v=KhwbCmDrXxA

The speakers discuss Agent RFT, OpenAI’s platform for fine-tuning reasoning models via real-time tool interactions and custom reward signals. They explain how reinforcement learning solves complex credit assignment challenges within the context window. They share enterprise success stories, showing how Agent RFT eliminates long-tail token loops and drives extreme efficiency.

Google has released A2UI v0.9, a framework-agnostic standard for AI agents to declare user interface intent across multiple platforms without arbitrary code. The update emphasizes alignment with existing design systems. It includes a new SDK for Python, improved error handling, and various transport methods. Migration guidance and evolution specifications are also provided.

Announced at WWDC 2026, the latest SwiftUI release brings a new Document protocol for efficient disk access and snapshot-based updates, along with improved APIs for reordering items in lists, grids, and sections. In addition, it expands presentation features, such as swipe actions on any view, better AsyncImage caching, and lazy state initialization for Observable types to boost performance.

A company shifted from project- to product-thinking after their platform outgrew single-team use. The limitations that they felt with their platform were one-off deliveries, lack of product vision, and weak feedback loops. They have moved toward a self-service, API-driven, multi-tenant infrastructure with clearer ownership and better abstractions.

Apple chose Google Cloud to run Private Cloud Compute outside its own data centers for the first time, using NVIDIA Blackwell GPUs, Intel TDX, and Google's Titan chip. Apple maintains an independent append-only hardware ledger and dual-vendor attestation roots. AWS and Azure are not part of the collaboration.
