A Post-Apocalyptic sun.misc.Unsafe World by Christoph engelbertJ On The Beach
The announcement that sun.misc.Unsafe will disappear in Java 9 created a huge buzz in the community and lots of people didnt agree with the idea. While Unsafe have to go away eventually the time in not yet and Oracle finally agreed on that. To replace sun.misc.Unsafe we need a clear set of APIs to achieve the same behavior and performance. VarHandle, Foreign Function Calls, Generic Specialization (Templates) and other proposals try to solve this misery and to replace certain aspects of our beloved class. This talk will introduce the alternatives and explain how and why they will help to replace sun.misc.Unsafe. It uses basic examples to demonstrate what a Post-Apocalyptic Unsafe World will look like.
Set up faster, easier, end-to-end testing with CircleCI and CypressMagnolia Triplett
Learn how to set up Cypress on CircleCI to maximize end-to-end testing efficiency.
Running a complex tool on a continuous integration (CI) server can be a frustrating experience if you run into tricky config errors. Luckily, CircleCI orbs provide a simple way for teams to write their CI config without needing to do all of the heavy lifting.
The team at Cypress has written the official Cypress orb to help users easily test their web apps on every commit without dealing with common configuration mistakes. In this webinar, you will learn how to use the Cypress orb to run end-to-end tests against different environments to help make your team fully confident in your web applications.
Jonathan Corbet - Keynote: The Kernel Reportlinuxlab_conf
A whirlwind tour of what has been happening in the kernel development community and what can be expected in the near future.
The Linux kernel is at the core of any Linux system; the performance and capabilities of the kernel will, in the end, place an upper bound on what the system as a whole can do. This talk will review recent events in the kernel development community, discuss the current state of the kernel and the challenges it faces, and look forward to how the kernel may address those challenges. Attendees of any technical ability should gain a better understanding of how the kernel got to its current state and what can be expected in the near future.

Getting Started with JDK Mission ControlMarcus Hirt
Here are the slides for my talk on how to get started with OpenJDK Mission Control. Most of the talk was spent with demos, so not sure how useful this will be.
Microservices with Terraform, Docker and the Cloud. JavaOne 2017 2017-10-02Derek Ashmore
Much has been written about how to write Microservices, but not enough about how to effectively deploy and manage them. Microservices architecture multiplies the number of deployables IT has to manage by at least 10x. In that world, tooling to manage cloud deployments and related infrastructure becames essential for success. Terraform and Docker are increasingly being leveraged to facilitate microservice environments. Terraform has become becoming the leading coding framework for building and managing change in cloud environments.
Attendees will learn best practices for deploying and managing microservices in production. We will leverage true "infrastructure as code" using Terraform. That code is easily re-used and make changes easy. That code makes it easy to deploy and scale software including Docker images. You will learn not only how to establish that environment initially, but how changes can be effectively managed. I'll cover best practices and common mistakes along the way. AWS will be used as the cloud provider, but Terraform operates seamlessly on other cloud environments as well.
This session is targeted at architects and team leads. This session is intended to be platform-generic.

Whether you are a Zowe User, Contribor, Extender or simply interested in what's happening with Zowe - please join us for the launch of the Zowe Quarterly Update Webinar. This is the first in the series of webinars we plan to host each quarter. The webinar will include:
A focus topic / speaker
A brief Zowe update
Upcoming Community Events Overview
Interactive Polls
Join us on this webinar to learn how we are extending the Zowe ZSS (z/OS back-end) to facilitate building in-depth (cross-memory, privileged, system-level) mainframe products with little-to-no assembler code required.
Using XPages out of the box lets you build good looking and well performing applications. However, as XPage applications become bigger and more complex, performance can become an issue and, if it comes to scalability and speed optimization, there are a couple of things to take into consideration. Learn how to use partial refresh and partial execution mode and how to monitor its execution using a JSF LifeCycle monitor to avoid multiple re-calculation of controls. We will show tools that can allow you to profile your code, readily available from OpenNTF, along with a demonstration of how to use them to improve the speed of your code. Still writing SSJS and encounter a significant slow down when using Script Libraries? See, how you can improve the speed of your application using JAVA instead of JS, JSON and even @formulas.
Slides form Config Management Camp, looking at how you can take a collaborative GitFlow approach to Terraform using Remote State, Modules and Dynamically Generated Credentials using Vault
This talk celebrates the Eclipse Modeling universe through a condensed presentation of 15 cool projects - mostly frameworks - to push your EMF usage beyond its limits.
For each project : its scope, an example and feedback from the trenches. It's gonna be fast, you're going to discover new projects, you're going to learn what we built with it and how we feel about it. No less, no more, but 15 times.
You don't know EMF yet ? This talk will give you a clear vision of why you might want to use it.
You already know EMF ? You will discover new components and usages which makes this framework shine.
StorageQuery: federated querying on object stores, powered by Alluxio and PrestoAlluxio, Inc.
Alluxio Global Online Meetup

For more Alluxio events: https://www.alluxio.io/events/
Speakers:
Abner Ferreira, Simbiose Ventures
Caio Pavanelli, Simbiose Ventures
Bin Fan, Alluxio
Over the last few years, organizations have worked towards the separation of storage and compute for a number of benefits in the areas of cost, data duplication and data latency. Cloud resolves most of these issues but comes to the expense of needing a way to query data on remote storages. Alluxio and Presto are a powerful combination to address the compute problem, which is part of the strategy used by Simbiose Ventures to create a product called StorageQuery - A platform to query files in cloud storages with SQL.
This talk will focus on:
- How Alluxio fits StorageQuery's tech stack;
- Advantages of using Alluxio as a cache layer and its unified filesystem;
- Development of new under file system for Backblaze B2 and fine-grained code documentation;
- ShannonDB remote storage mode.
The Diabolical Developer's Guide to Surviving Java 9jClarity
The Diabolical Developer presents a pragmatic guide on running and compiling your application on Java 9. There are a lot of new resrtictions due to the Java 9 modular runtime, so make sure you read through carefully before your migration!
Are you a developer? How much time do you waste packaging your extensions, uploading them to your website, creating change logs, creating new releases, making announcements, etc? A lot! Sometimes it can even be a deterrent to new releases because it's so much work. Akeeba to the rescue! Akeeba has some great extensions (all with free versions!!) made for developers by one of the most well known Joomla extension developer. With a little shell script magic (disclaimer; nix/mac based script), Git, Akeeba Subscriptions, Akeeba Release System, and Akeeba Release Maker, I'll show you how you can handle all of the above with a single command.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

components > frameworks > open
source > usage at next projects
• Motivation
• Convenient way to touch with
partners
– Ask them to join your OS project and
see what happens
• All that is done for free in minutes, and
results in a week (productivity etc)

Open Source cons (то, что
всплыло на проекте)
• Weak communities
• Not always user
centric development
• Смешение
технологий – for
handy people
• Нет успокоения (но
и нет старпёрства)
• Customizations,
customizations,
customizations
• Effort on R&D

Money?
• Become committer with potential
customer
• Long investments
• Create popular industry/direction
(что сейчас делается в проекте
Texo)
• Конференции, где бывают
заказчики мира Java Open
Source
• Independent consulting
• Name
• A way to start cooperation with
people immediately
– For eclipse – not one month of
contribution
– For sourceforge etc.
• Create user
• Add to project
• Develop Use Case

CMS
• Good to have XSD support
– And recursion
• Good to become an entry point for all the
management/admin pages
• Good to be node specific
• Good to have web scripting
• finally flows
• And convenient management of renditions
• E-CMS integration should allow to do (web.xml,
configs, bundles, localization) in the way you use
wordpress

Bonus 00: j2ee vs ruby (basing on
mashpit trainings)• Context handling
• Много времени для
вхождения новичкам
• Хостинг дешевеет, clouding
• Java is up to have closures
• Byte code manipulators
• Aop, IoC, OSGI
• Simple syntax
• Proved technology
• MVC frameworks: spring,
struts, seam. Tons of views,
TDD
• ORM and JPA
• Ant, Maven
• Good to have compilation
errors

Bonus 01: расширяемое
программирование in Java
• Пляшем от полиморфизма
• Generics
• IoC(spring, self-made, seam, web.xml, context.xml)
• Dependency injection (interceptors, chains), AoP (joints)
• Patterns
• Plugins (self made, OSGI, etc.)
• WS-* (service mix, equinox, wsdl, JSON, REST)
• Bytes manipulation (create classes on the flight,
interception on the flight – hard to debug)
• Polymorphic systems (ruby frontend – java backend)
• Class loading art
• UI: widgets, web scripting
• MDD, TDD, CMS took important role
• Built in scripting
