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

AWS launched managed OpenClaw on Lightsail for AI agent deployment while security concerns mount. The 250k-star GitHub project is affected by CVE-2026-25253, which enables one-click RCE, with 17,500+ vulnerable instances exposed. Bitdefender found 20% of ClawHub skills malicious. AWS blueprint provides automated hardening, but doesn't address architectural security limits.

Elastic 9.3.0 is now available, featuring enhanced vector search indexing for RAG applications and significant upgrades to the ES|QL query language. The release deepens OpenTelemetry integration for vendor-neutral observability and updates the AI Assistant with better contextual analysis. Security visibility is also expanded across Kubernetes and serverless architectures.

To improve image cache management in their Android app, Grab engineers transitioned from a Least Recently Used (LRU) cache to a Time-Aware Least Recently Used (TLRU) cache, enabling them to reclaim storage more effectively without degrading user experience or increasing server costs.

Google Research has proposed a training method that teaches large language models to approximate Bayesian reasoning by learning from the predictions of an optimal Bayesian system. The approach focuses on improving how models update beliefs as they receive new information during multi-step interactions.

Cloudflare recently announced support for ASPA (Autonomous System Provider Authorization). The new cryptographic standard helps make Internet routing safer by verifying the path data takes across networks to reach its destination and preventing traffic from traversing unreliable or untrusted networks.
