Java One 2011 Day 1 (2nd of October)

This was not actually the JavaOne first day. Some sort of training day :) Keynotes, main presentations as well as exhibition and demo are starting at Day 2.
Impressions:
Moscone center is really HUGE. I haven't seen anything that could be compared to this place. Probably the one of the biggest exhibition centers in the world.
Presentations:
1. MySQL: Don't Be a Rookie Forever—Be in Command (Line) by Giuseppe Maxia @datacharmer
Great talk. Quite technical. Found a lot of stiff for myself. Felt satisfied because I'm not the only one who are using MySQL command line. Recommended to watch the presentation, read the author books. Listed below. Topics and quotes:

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).

Don't be a GUI rookie forever - Be in command! (line)

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.
