Java One is a Wrap!
Java One 2015 happened this week. There were so many interesting sessions you could nearly throw a dart at a dartboard with topics and go to the one you selected at random. For starters, here's a link to descriptions of the keynotes. And, you can check out the session descriptions here.
The Java language celebrates it's 20th year this year.Here's a free book you can download: Introducing Java 8: A Quick-Start Guide to Lambdas and Streams. Java SE 8 is perhaps the largest change to Java in its history, led by its flagship feature—lambda expressions. If you’re an experienced developer looking to adopt Java 8 at work, this short guide will walk you through all of the major changes before taking a deep dive into lambda expressions and Java 8’s other big feature: the Streams API.

Happy 10th year, JCertif!

Presentation: How to Build an Exchange: Sub Millisecond Response Times and 24/7 Uptimes in the Cloud
Frank Yu shares Coinbase’s engineering philosophy for building resilient, fair, and fast financial exchanges. He explains the power of a single-threaded architecture combined with the Raft consensus algorithm to maintain 24/7 availability. He discusses how determinism enables zero-downtime rolling deployments and the ability to replay production logs for perfect bug reproduction.

Cloudflare has released Sandboxes and Containers into general availability, providing persistent isolated Linux environments for AI agent workloads. New capabilities include secure credential injection via egress proxy, PTY terminal support, persistent code interpreters, filesystem watching, and snapshot-based session recovery. Active CPU pricing charges only for used cycles.
By Steef-Jan WiggersArticle: When a Cloud Region Fails: Rethinking High Availability in a Geopolitically Unstable World
Sovereign fault domains are failure boundaries defined by legal, political, or physical jurisdiction rather than hardware topology. The article maps geopolitical events to known distributed-systems failure modes, argues multi-region should replace multi-AZ as the HA baseline for systems crossing jurisdictions, and outlines design patterns, chaos experiments, and an ALE model to justify the spend.
