Recently I had the pleasure to participate in the conference 4Developers , which surprised me very positively in terms of content. Four parallel paths that really was made to choose from.
At first the fire Adam Bien a lecture entitled EJB 3.1 - Killing The Top Eleven Myths, Tales and Biases . For quite a long time worked EJB3 technology, have come to this lecture with pretty large expectations and - I admit - I was not disappointed. Adam led a tangible, persuasive speech and not for a moment not przynudzał:) rate in the same time, and even elements of humor have happened. Adam purpose was to fight the myths that say that EJB3.x are "heavy" and difficult to test, implement, etc.. Adam placed great emphasis on the upcoming EJB3.1, for example, where you can "manually" (in code) to start the EJB container (now possible with OpenEJB, but will enter the standard). Unification will also JNDI-names of components, which will help to achieve true portability of applications between application servers.
As the second section there is a Java Neal Ford with a lecture titled The Productive Programmer : Mechanics. In this case also no disappointments - Neal presented an interesting work on optimizing the developer, presenting a variety of support tools. He showed that improving the simplest tasks like copying to the clipboard or to navigate the directory tree, we can gain a lot of time. Neal placed great emphasis on the need for a good understanding of your IDE and particularly its use with the keyboard.
As the third occurred on the path Javowej Cornel Creanga Flex presenting opportunities in conjunction with Java. Unfortunately, this lesson is not impressed by the content or style of presentation, but Maybe my opinion is in part due to the fact that this subject interests me less. The presentation was confined to przeklikania demo applications taking advantage of the Flex. Quite an unpleasant surprise was some element (unless the speaker), which fell from the ceiling and hung on wires over the head of one of the participants in the lecture - very nearly ...
then moved to a room where there were lectures from the path of Project Management, to listen to Adam Krosnego the company Alan Systems . Adam led a very interesting and comprehensive lecture on the practice of placing SCRUM methodology. He described the process of implementing this methodology in terms of practice, providing the theoretical basis. Also in the "backstage" I have heard many positive opinion on the lectures (eg, someone said it was the most essential lesson of all lectures sponsored.) subject presented by Adam met with great interest unless packed in 100% of the room - many people asked questions, which the lecture was somewhat prolonged, but it was worth it:)
Martin Żuchowicz with e-point presented a problem of large IT projects from a practical point of view. Lecture interesting, sometimes funny (eg, project description Ajax with several bedrooms filled with documentation;)) The main conclusion to which the speaker sought to need a strong commitment to client-side manager and his ability to convince their superiors that it's sometimes useful to change the requirements in the name of a good project.
Then I went on a lecture by Ted Neward 'and who talked about Scala. Ted, like Neal Ford (ThoughtWorks both of) a conference "stager", this time also did not disappoint. Summarized the basis of Scala as a language independent, as well as possible for use from Java. Repeatedly emphasized the advantages of Scala compiler in comparison with javac - such as the maturity of the semicolon at the end of the expression (Scala does not require this), or having determining the type of the variable in the declaration (on the left).
The last occurred Jacek Laskowski which roused the audience a bit tired now. Jacek talked about Groovy and Grails, and although - as is sometimes the presentation-not everything worked, at least theoretically learned more about these mechanisms. Despite the late hour Jack was able to engage the audience in his lecture, and even a minor slip associated with the operation of the examples were rewarded with applause;)
After the conference was the level of substantive I think high. I would even say that it was better than the previous two JDD. The only thing missing is a lunch and parking. Break for lunch at which all run out of the city, and there in all the restaurants coming hordes of developers - it's not a good idea;)
