What is Groovy and why should I care?
Hello again, it's me, Adam. Earlier this year, I finished my self-published book, Learning Groovy, which is about, well, learning Groovy. It also covers the top Groovy-based tools and frameworks, Gradle, Grails, Spock, and Ratpack.
I've enjoyed using Leanpub as a place to work on my books (What's new in Java 8 and others). It is really easy and developer friendly. It uses a Dropbox folder and you can write your book in Markdown (which I did). I've enjoyed a fairly constant trickle of purchases, but I was frustrated that I never had enough time to devote to the other huge part of self-publishing: marketing. To be really successful with a book, it needs to be marketed really well. You need to put in a lot of time and money. So, when it came to publishing "Learning Groovy," I approached several publishers to do the marketing for me.
Luckily, one of them accepted, and I'm currently in the process of final edits (publisher shall remain anonymous for now).
This means that you can only get the self-published version of "Learning Groovy" for a limited time. Once it goes to the publisher, I have to take down all my versions per the contract.
"What is Groovy and why should I care?" you ask? First of all, what rock have you been living under? Secondly, Groovy is a mature and flexible open-source language that runs on the JVM. Want to learn more about functional programming, want optional dynamic typing, easy restful services, easy reactive web applications (Ratpack)? Maybe you to learn about the most popular build framework and testing frameworks for Java (Gradle and Spock)? Groovy is where it's at.
Codetown is a social network. It's got blogs, forums, groups, personal pages and more! You might think of Codetown as a funky camper van with lots of compartments for your stuff and a great multimedia system, too! Best of all, Codetown has room for all of your friends.

The Swift SDK for Android, recently released as a nightly build, is designed to help developers to port their Swift packages to Android, making it easier to share code across platforms. While the SDK is still in preview, over 25% of packages in the Swift Package Index can already be compiled for Android.

Ian Miell shares the open-source Continuous Compliance Framework (CCF), a tool for modernizing audits and controls. He explains how current manual, periodic compliance fails, especially with new regulations like DORA. He demonstrates how CCF leverages DevOps principles, agent-based architecture, and the OSCAL standard to provide continuous, centralized visibility across hybrid estates.

Netflix uses a Write-Ahead Log (WAL) system to improve data platform resilience, addressing data loss, replication entropy, multi-partition failures, and corruption. WAL decouples producers and consumers, leverages SQS/Kafka with dead-letter queues, and supports delay queues, cross-region replication, and multi-table mutations for high-throughput, consistent, and recoverable database operations.
