Foxmarks - an excellent Google Browser Sync alternative

I have been using Google Browser Sync for a long time but it is no longer supported by Google now. I was looking for a good alternative and I have chosen Foxmarks. The reason why I picked Foxmarks over other products (like Google Bookmars) is that is allows very smooth integration with Sage (which is my favorite fead readed). And the reason why I prefer Sage over Google Reader is that it supports folders...

TSSJS Prague 2008

I have just learned that I missed TSS Java Symposium in Prague this year!

Agenda looked pretty interesting. It seems that cloud, grid and concurrent computing is going to be the next buzz word which every developer has to add into CV soon next to Spring, JPA, Hibrnate, Grails and Groovy stack (tracks about Scala, MapReduce, DataGrids ...).

Well, I hope that I won't miss it next time and that at least the slides will be available soon. As of now I was able to find Shay Banon's Beyond the DataGrid (it specifically mentions Hadoop as well).

HSQLDB - Closing Database Connection

If you are using HSQLDB and you are getting exceptions like:

Could not get JDBC Connection; nested exception is java.sql.SQLException: The database is already in use by another process ...


java.lang.Exception: The process cannot access the file because another process has locked a portion of the file ...

then you probably need to close the database connection correctly.

Call the following method:

For example if you are using HSQLBD in your unit tests then it is necessary to call org.hsqldb.DatabaseManager.closeDatabases(0); in every tearDown() method in each unit test.
