Ну а теперь непосредственно о докладах:

1. Keynote от Patrick Chanezon

Обзорный доклад для тех, кто еще не в курсе что такое CF и каково ее место (по мнению VmWare) в современном мире.

2. Spring 3.1 Review & 3.2 Preview  от Chris Beams

Замечательный доклад с обзором того, что мы уже давно видели в Spring 3.1 и того что еще не пробовали в Spring 3.2. Достаточно много практических примеров и кода, правда доклад явно не вписался в регламент 60 минут. Рекомендую посмотреть материалы.

Для себя отметил много новых фич 3.1 связанных с @Configuration и XML-free конфигурацией. Аналогично руки не доходят до новых фич @MVC, в первую очередь поддержка Servlet 3.0 и особенно асинхронных запросов.

Слайды тут.

3. Spring MVC & Multi-Client Development by Josh Long

Обзорный доклад о Spring MVC.  Для тех кто давно на ты с этим модулем Спринга, пожалуй ничего особо нового в первой половине презентации нет, возможно, кроме того, что  Josh показывает как быстро “построить” проект с использованием Spring Roo. Вторая часть доклада выглядит интересней, в ней рассказывается о работе с REST, Spring Android.

Код примеров можно найти тут.

4. Enterprise Integration Patterns with Spring Integration by Oleg Zhurakousky

Интересный доклад показывающий как SpringIntegration реализует EIP подходы. Я бы сказал что доклад скорее предназначен для того, чтоб показать, что Apache Camel вам не нужен. На мой взгляд, хоть SpringIntegrations и удобен, но гораздо удобнее, для большинства задач использовать уже готовые тимплейты (например для JMS) чем писать на “чистых” каналах. Это своего рода вождение на “ручке”. Слайдов именно этого доклада не нашел, но в Сети очень много докладов Олега.

5. NoSQL options with SpringData by Costin Leau

Из-за отсутствия слайдов доклада, мой рассказ о нем будет не столь структурирован. И, конечно я могу что-то пропустить. Суть в том, что давно изъезженное вдоль и поперек поле persistence слоя построенного на RDBMS уже не является “неизменно превосходным результатом”. Индустрия требудет “Даешь NoSQL!!!”. И в то время как JBoss пытается избрести велосипед JPA for NoSQL (смотри проект Hibernate OGM), Spring решил не отставить и вплотную занялся вопросом в рамках SpringData. Spring и до этого предоставлял Mongo и Redis templates для работы с этими БД по примеру старого доброго (ныне правда deprecated) HibernateTemplate. Кроме того поддерживается “нативные” интерфейсы. Аналогичная ситуация с Neo4j в проекте SpringGraph (подпроект SpringData). Часть доклада повествовала о том, что Spring разрабатывает подход в котором фреймворк будет сам генерировать мапинги для указанного хранилища, а также хотел бы сделать LINQ для Java, но тут мне показалось что речь идет про “космические корабли, которые бороздят просторы Большого Театра”.

6. Batch & Hadoop Workloads with Spring by Costin Leau

Сбылось “то о чем так долго говорили большевики”, а именно Hadoop стал еще ближе и проще – появился SpringHadoop. Слайдов доклада не нашел, но он почти полностью повторяет этот пост. Теперь в Spring приложение можно не только легко интегрировать HDFS, но и писать MR таски с использованием спрингового инструментария. Как обычно поддерживается все на свете, а именно использование Pig/Hive.

Остальные материалы тут.

Андрей рассказал часть своего тренинга по углубленному TDD. Понравилось обилие примеров и доступность. С утра немного не поспевал за докладчиком. Для себя отметил использование библиотеки FEST. Докладом очень доволен

2. “Approval Tests как альтернативный взгляд на автоматизированное тестирование” Александр Белецкий

Тема доклада была очень интересной, но на мой взгляд Александр позволил увести себя в сторону вопросами. В итоге не смог показать все заготовленные примеры. Также в очередной раз убедился что что при регламенте 50 минутного доклада live coding невозможен, насколько бы ты не был быстр за клавиатурой. Как Java разработчик отношусь с подозрением ко всему что было разработано дотнетчиками, но все равно попробую. Основные материалы по approval testing.

Слайды.

3. “Experience TDD and pair programming” Johannes Brodwall

Johannes при помощи Дмитрия Миндры продемеонстрировали практическую сессию парного программирования с использованием пинг-понг техники. Большое им за это спасибо. Давненько не видел ничего подобного, сразу пожалел что не попал на coding dojo.

4. Tools Talks
Talk #1 : Александр Коротких

Докладчику немного не хватило опыта для интересной подачи материала, а материал был конечно интересный – Использование Git для Agile проектов. Хоть сам я и отказался от Git в пользу Mercurial слушал с интересом.

Talk #2 : Максим Кузьмич

Коллега из Беларуси разложил по полочкам Crucible  от Atlassian. Очень грамотный доклад.
Talk #3 : Дмитрий Миндра

Дмитрий рассказывал свой любимый доклад про Software Craftsmanship. См. тут. Как обычно жег по полной

5. “Разворачиваем инфраструктуру для автоматизации функционального тестирования веб приложений” Андрей Дзыня

Не мог не поддержать коллегу и товарища. Как выяснилось очень правильно сделал – Андрей оказался в окружении разработчиков и ему не помешала небольшая поддержка. Андрей рассказал о внедрении автоматизированного тестирования UI для веб проектов с использованием Selenium. Слайды скоро должны быть.

6. Ваш покорный слуга с докладом о психологии Code Review.

Своим докладом оказался более-менее доволен. Карточек правда получил аж одну . Но зато смогу немного расшевелить аудитории и вовлечь в дискуссию на очень интересную и тонкую тему.

7. “Continuous Delivery” Николай Алименков
Николай разложил по полочкам такой нынче популярный процесс как непрерывная доставка. Единственное что хотелось бы ему заметить, так это то, что Feature Flags все таки были придуманные в канадской Flickr. Слайды думаю скоро будут.

2. Java EE Cluster Management Strategies by Chris Kasso (Principal Member of Technical Staff Oracle) and Jennifer Chou (Senior Member of Technical Staff Oracle) and Thomas Mueller (Principal Member of Technical Staff Oracle)
GlassFish development team members explained the main challenges while building Java EE cluster. Interesting talk. Could not find the slides.
Main topics and quotes:

Cluster management life cycle challenges:
- Configuration
– Monitoring
– Failures

Management strategies:
Centralized configuration management – data replication, highly available storage, operation replication (deploy,update). Server is NOT processing user requests.
Standalone instances – User or the 3rd party system do the work. Additional work vs freedom.
Distributed management – Master + “Standby masters”. All servers are processing requests (Resin).

Instance management :
Centralized per-host controller talk to OS to start/stop services.

3. CDI Today and Tomorrow (open panel)
Panel was lead by Arun Gupta from GlassFish team. Panel members:
Pete Muir, RedHat, Spec Lead for CDI 1.1
Sivakumar Thyagarajan, GlassFish team
Davis Blevins, Apache OpenWebBeans
Reza Rahman, CanDI

Nothing really new. JBoss Weld will be taken as a reference implementation for the CDI 1.1

Quotes:
All existing CDI implementations already have a JavaSE mode
But CDI won’t be in JDK
CDI 1.1 would have SE mode specified

4. Serialization: Tips, Traps, and Techniques by Steve Poole (Software Engineer IBM)
Steven is a JDK team member. A good metaphor was used to explain serialization tips – human teleportation.
Still looking for the slides
I’ll pay more attention to this topics later on.

5. Java EE and Spring/MVC Shoot-out by Reza Rahman and Rohit Kelapure (IBM)
The drums of war thunder once again. From the other way around a good summary of JavaEE vs Spring features in one presentation. So it’s up to you to decide which one is better for your particular problem. But I still don’t understand why JSF is better than any of the Spring MVC presentation. You are free to have  your own opinion.

Slides are here.

That above is the last part of my JavaOne 2011 review posts, please contact me with your feedback.

2. Project Coin in Action: Using New Java SE 7 Language Features in Real Code by Stuart Marks (Principal Member of Technical Staff Oracle)
One more about JDK 7 features. Recommended.
Slides here.

3. The Road to Java EE 7: Is It All About the Cloud? (panel discussion)
The panel consisted of the following people:
–Adam Bien, Consultant, Author, Java EE Expert
–David Blevins, Apache Software Foundation
–Emmanuel Bernard, JBoss Platform Architect, Red Hat
–Reza Rahman, Senior Software Engineer/Community Outreach Activist, Caucho Technology
–Linda DeMichiel, Java EE 7 Specification Lead, Oracle

Main topics and quotes:
Things to be small in EE 7
Change of deployment model
Containers should be lighter
API’s first than cloud
Right step would be to have a cloud which supports JavaEE
Multi-tenancy should be addressed as a feature
PaaS deployment are missing business details
JavaEE 7 is not just about the cloud but service provisioning
Multi-tenancy is the challenge
Many JSR’s are focused in the usage improvement
XML descriptors would probably come back

4. Asynchronous Job Execution in the Cloud by Alex Snaps (Senior Software Engineer Terracotta)
Alex summed up all problems which we are facing when doing a Task Scheduling and execution in a cluster and cloud.
Slides are here.
A PR talk about Terracotta products.

5. Patterns and Best Practices for CDI by Reza Rahman (Senior Software Engineer/Community Outreach Activist Caucho Technology) and Ryan Cuprak (e-Formulation Analyst Dassault Systemes)
The presentation is now available here.
The presentation on my mind is quite controversial. Probably the only interesting part is about scopes.
My conclusion:
CDI is a kind of unfinished spec with a lot of provider specific features.

6. Experiences with Java EE-Enabled PaaS by Anil Saldhana (Lead Middleware Security Architect Red Hat) and Scott Stark (Vice President – Technology Red Hat Inc)
Guys from RedHat presented main features of the OpenShift – Java PaaS from JBoss. I liked simply explanation about “what’s in there”. BTW Puppet again. Security aspect was also covered.
It’s a pity that I could not find the demo code.
Slides are here.
Recommended to all that wanted to start with JavaEE PaaS.

1. Java Strategy Keynote
Once again you are welcome to see the full video:
http://medianetwork.oracle.com/video/player/1176404813001

2. Java Enterprise Applications in the Cloud: Fast, Fun, and Easier Than Ever by Gordon Dickens (Consultant/Instructor/Mentor Chariot Solutions) and Stefan Schmidt (Software Engineer Spring Roo VMware)
I was very impressed by the presentation. Simply because it took us a lot of time to have an app deployed to GAE and now it’s done … very fast. OK this is a petclinic/pizza shop app, but is has all the infrastructure. DB reverse engineering feature is awesome.

By now found only this one:
https://github.com/gordonad/spring-roo-heroku

3. Infinispan by Manik Surtani (RedHat, spec lead for JSR-347)
First time I heard about Infinispan at GeeCon this year. Emmanuel Bernard mentioned it during his Hibernate OGM presentation. Infinispan is the distributed transactional KV storage. JBoss insist that Infinispan is more DataGrid or Distributed cache than a KV NoSQL storage.
Could not find the presentation slides .

4. Java EE on Google App Engine: CDI to the Rescue by Ales Justin (Software Developer Red Hat inc.)
Basically the presentation was a case study on how to use CDI (JBoss Weld) with GAE and why it’s needed. Have only a few notes about it. Probably it was not very useful for me.Could not find any material about this talk by now. I’ll try to add some later on.

5. Strategies and Best Practices for Highly Scalable Java Persistence Applications by Doug Clarke and Gordon Yorke (both from Oracle)
Great presentation with a set of practical advices on JPA optimizations.
Could not find the slides for this particular presentation but found Gordon’ slides about EclipseLink:

Main topics and quotes:
Measure performance in regression
Providers have profilers already
Inspect @Cachable
Mapping optimization – balancing between Single table and Table per class
Use @Embedded or @Embeddable instead of @OneToOne
Pay attention to collections
Use projection, pagination, named queries, query caches
Keep number of managed entities small
Threads could be bottleneck on synchronization access
Consider locking

6. JSR 343: What’s Coming in Java Message Service 2.0 by Clebert Suconic (Principal Developer and HornetQ project lead Red Hat) and Reza Rahman (Senior Software Engineer/Community Outreach Activist Caucho Technology)
A great overview of the upcoming and existing JMS features.
Still looking fro slides.
Topics and quotes:
JSR 343 – JMS 2.0 early draft
JMS has many wrappers just because it’s not comfortable to work with it
JMS 2.0 is about API improvement
Reducing number of classes
Attention to multi-tenancy

7. Are Your Garbage Collection Logs Speaking to You? by Kirk Pepperdine (Performance Specialist Kodewerk Ltd.)
It’s always a pleasure to be at Java Champion presentation. Very informative. A reminder that GC logs is important to read and systematically analyze. Looking for slides.

8. How Do You Update Your Java EE App in Production? by Jevgeni Kabanov (CTO ZeroTurnaround)
A presentation from JRebel creator. Quite interesting analysis of existing situation on product redeploy in production. LiveRebel product PR. But there are two tools that I decided to invest my time to Chef and Puppet

General stuff:
Try out SpringRoo with Heroku, CloudBees and CloufFoundry

1. JavaOne Technical Keynote

Could be found at http://medianetwork.oracle.com/video/player/1176404809001

You should watch it. No comments.

2. Best Practices for Migrating Spring Applications to Java EE 6 by Bert Ertman and Paul Bakker from Luminis Technologies

Quite a controversial topic, but quite interesting from the technical perspective. Starting from this particular talk I understand that JBoss started a war with SpringSource for the 1st place among JavaEE platforms.

Topics:

Spring is the proprietary framework developed by a vendor who is in virtualization business

Spring does not support JavaEE

Spring + Tomcat is slower not faster than modern JavaEE containers

AOP = Evil

Source code could be found here.

2. Continuous Integration with Jenkins by Kohsuke Kawaguchi
It’s nice to see the Hudson/Jenkins creator. Great talk but the first part was quite abstract and targeted to prove that Jenkins it better than Hudson and that Eclipse is wrong by supporting the last one. Still could not find the slides.

Interesting topics:
Jenkins now is not only the CI server but the code reviewer and test system. Kohsuke showed a useful integration with Gerrit, when the tests are run against the local branch before the code is pushed to a server.
This could not be reproduced for the mercurial, but there is a workaround for SVN.

3. Apache Cassandra for Java Developers by Nate McCall @zznate
Nate quickly explained the Cassandra basics and jumped to the API (Hector). The presenter speed was quite high so I tried to do my best to be on the same page. As a result a could not remember most of the presentation

GitHub: https://github.com/zznate/cassandra-tutorial

https://github.com/zznate/hector-examples

Main topics and quotes:
Cassandra has no ACID transactions
Static/Dynamic column families
Pre-calculated query results
Column family templates – analogue of Spring JDBCTemplate
Take a look at Hector JPA (GitHub)

4. Project Jigsaw: Putting It Together by Mark Reinhold (Chief Architect, Java Platform Group)
Mark explained the problems his team faced while developing new packaging/module system for Java. Could not find the slides.

5. JVM Bytecode for Dummies (and the Rest of Us Too) by Charles Nutter (JRuby Architect Engine Yard)
Charles probably the first person who explained using simple examples what is bytecode actually is. I’ll probably post more in this topic later on.
The first person who answered the question about finally block

6. Simplify Your JMS Code with Spring by Bruce Snyder (Senior Software Engineer SpringSource)
Bruce explained features and usage of JMS template in Spring. Some of the stuff I already knew, some of it I was not.
Slides.
GitHub: https://github.com/bsnyder/spring-jms-examples

General topics:
Pay attention to the Arquillian framework

Giuseppe recommends to use Unix pipes for query execution. Aliases is very useful (i.e. alias myself =mysql). There are batch mode and table mode for the query results. Functions usage with $(function).

2. Importing and Exporting Data Between Hadoop and MySQL by Sarah Sproehnle
Interesting talk. Found a lot of interesting about Hadoop and it’s tools. Sqoop allows to import data from RDBMS to have some sort of general data storage in Hadoop. Hive is the SQL for NoSQL.
Now I know more about Cloudera products.
Slides are here.

3. Explaining the EXPLAIN in MySQL by Ronald Bradford
Everything about EXPLAIN that I didn’t know and always tried to find out. Slides.

4. JCP members panel
A very disappointing talk for me because the JUG’s are weak in Ukraine and in particular in Kyiv. JCP members explained the new JCP approach to the specification development. New approach means that JUG should should influence more on the expert groups. Because specs developed only by vendors expert groups are far away from the “trenches” and not useful on a real projects.

Books:
Unix power tools
Big data analysis with Hadoop MapReduce (article)

Presentations:

1. Jurgen Appelo “How to Change the World”

Jurgen presented some of the main ideas of his book “Management 3.0“. Once again “it’s all about the people“. Jurgen described 4 main facets of social change. I’ll try to get the book soon. Recommended.

2.  Danny (Danko) Kovatch @DankoAgile “Motivation 3.0 and Agile”

Danko told us about what does modern science think about the motivation and what companies are doing about it. The difference is HUGE. Recommended. Not a new topic for me, I was bored a little in the middle of the presentation.

3. Lasse Koskela “Agile Workflows for Version Control”

I liked the content of the presentation where two approaches to the Agile branching strategies was compared, but I don’t get the why it was given so much time for arguing. Could not find the slides.

4. Lightning talks

5. J.B. Rainsberger “The Extreme Decade: Progress, Pain, Paradox”

Probably the best Agile presentation EVER. Recommended. And the final slides about post-Agile is probably the best thing a I’ve ever seen. Thank you JB! The final video (on “What we’ve done with the Agile?“). Could not wait till I see the video.

Books:

• The Lean Startup (mentioned about 20 times at least)
• Specification by Example (author was presenting)
• Management 3.0 (author was presenting)
• Innovation Games

Things to try or think about:

• Get a web camera
• Some ideas for my presentation about he Code Review problems in the teams
• Try Reflection workshop’s
• Read more about PDCA cycles
• Try to get live feedback from team members on my current project
• Try Cucumber or JBehave

Overall impression:

A lot of new faces (last year I can name at least one third of audience).  Same string quartet during conference opening coffee brake. Personally I don’t get the issue with the badges… Peace of paper without the plastic cover. Till the end of the day most of the people had to repair them. QR code with the visitor contact data on the badge  - great stuff.  Good for possible employer and for meet-up.  Wi-fi quality is the same, means that if you want to have a stable connection  - use your own mobile Internet. Android app is quite useful. I must confess that I don’t not fully understand the organizers PR move  ”Agile is an adventure“.

Let’s  move forward to the presentations I participated:
1. Dr. Alistair Cockburn “Effective Software Development In The 21st Century: The New Face Of Software Engineering”

I found Alistar’s talk very inspiring, but at the same time very abstract. The keynote basic idea is “it’s all about people“. That would not be Alistar if he would not talk about new certification, courses and stuff. It’s all about the people of course but also it’s all about the money . Slides in here. Among the quotes: “Agile is the mind set”

2. Sven Röpstorff “The fast-tracked story point oracle”

I liked a workshop very much. I’ve learned a couple of new estimation techniques. The slides is on the Slideshare. Had a conversation with Sven and find out that we both know a couple of German Agile coaches small world.

3. Lightning talks

A new format for AgileEE. Presentation should take about 8 min, with- or without the slides. So to the talks:

Dmytro Mindra @dmytromindra “Software Craftsmanship Revealed”

Really great talk about the craftsmanship and why tthe SW development is craftsmanship. Dmytro’s presentation is better and better time after time. That is a geed example of right approach to the things you do. I keep a wrist belt still because I REALLY promise not write a crappy code.

Dima Malenko @dmalenko “Just Do It”

Very inspiring talk. Recommended. The first step is the most important and the hardest among all future steps.

Artjom Serdyuk @ek_artem “Why do they leave? And how make them to stay”

Artjom focused in the “people and interactions” once again. Also recommended. Slides.

Alexander Lutsaevsky @AlexLuts “The Kama Sutra of Retrospectives”

Alexander answered to a question “what to do if something is going wrong during your retrospective”. Recommended.

J.B. Rainsberger fired up a short talk about SW product complexity and TDD. No slides. Great!

4. Piotr Zolnierek @pzol “Holistic Deployment”

A very very strange talk. Now looking to the slides I could not remember what exactly Piotr tried to tell us about. The presentation is about deployment and production deployment strategies. Nothing new or inspiring.

5. Andrea Provaglio (http://www.beyondagile.com/)  “Overcoming Self-organization Blocks”

Really great talk. Andrea is explaining what really “self-organizing” means and why it is so important. Quotes and thoughts: “Educational system is not up to date with the industry”, “Adult to Adult instead of Parent – Child interactions”,  ”Rowing against the tide”, “if you change something inside  - something outside changes as well”

6.  Elisabeth Hendrickson @testobsessed “Agile Testing, Uncertainty, Risk, and Why It All Works”

Probably the best talk of the day. The purpose and the meaning if the therm “testing” is defined very clearly. And the triangle “Intentions  = Actual needs = Implementation” is great. Recommended!!!

Other topics:

I decoded to place a book list and “stuff to think about” at the end of the Day 2 report
