And now for part 2 of my visit to Geecon 2011!<\/p>\n
Now this was awesome! Jim Webber, a former ThoughtWorks<\/a> employee, now Neo4j evangelist (in Neotechnology<\/a>) described his views on how SOA should look \u2013 according to him. This was presented previously, on other occasions as his \u201cGuerilla SOA\u201d talk \u2013 generally he advocated for REST based services, loose contracts (stating that WSDLs are too verbose and code generation is evil).<\/p>\n Jim mentioned Martin Fowler\u2019s article on integration databases but I couldn\u2019t find it anywhere \u2013 thou the topic looks interesting. He also recommended BDD<\/a> and exposing tests on the web for the end user to use them as early as possible.<\/p>\n One big point he made his case with was not relying on enterprise software<\/b>. Simple tools can do much better job. He compared implementing Web Services security (Secured SOAP over HTTP over TCP IP) to REST based service accessed through HTTPS<\/i> \u2013 basic and easily testable with tools like curl<\/a>.<\/p>\n Great talk. One of the best!<\/p>\n I must confess, that this did not go too well. The whole talk was well prepared and laid out but it lacked depth. It was pretty basic introduction to regex. From the presentation\u2019s subject I was rather prepared for some novel uses of regex \u2013 like for example: showing how to filter big volume of data with simple regex or sth.<\/p>\n But the talk was fun, Staffan is a good speaker. He is also an author of pomodoro technique<\/a> book \u2013 I intend to read sth abut this technique and this may be a nice start<\/p>\n If it comes to titles I tend to rely on them pretty heavily, however strange it may seem. This time I also did \u2013 and the whole talk did not give me a definitive answer to the stated question.<\/p>\n Sure, the presentation was informative, but it described some OSGI specific, quite low level stuff. Of course, if you want to use OSGI \u2013 even by leveraging application server with OSGI under the hood \u2013 you should know a fair bit about the technology itself. Even thou the AS does a good job of hiding OSGI container specifics from the developer, in case of problems it\u2019s better to be well informed. All in all \u2013 the talk gave too little information for me.<\/p>\n \u201cParallelism is not hard, multithreading is\u201d<\/b> \u2013 this was the key sentence of the presentation. The speaker showed how to introduce concurrency into normal java\/groovy code by sprinkling it with concurrency powder. Easy enough! With GPars<\/a> library he showed:<\/p>\n Good talk, well received!<\/p>\n Technical introduction to the world of bytecode, jvm specification details. I\u2019ve drifted away to some other topics \u2013 really \u2013 can\u2019t recall what this was all about.<\/p>\n This was a nice talk covering Groovy, Scala and Closure. The whole point of it was to show how cool it is to play with emerging JVM languages. They are not only fun but also useful. What\u2019s more, they bring freshness to java world, injecting it with some new paradigms and methodologies. It is easier to incorporate new ideas into younger JVM languages than to the mature Java.<\/p>\n2. Staffan Noteberg<\/a> \u201cRegex \u2013 the future programming\u201d<\/h2>\n
