As our current R environment still uses R-2.1, the latest ROracle-0.5.8 can not be installed (minimal requirement is 2.3+). Instead, we tried to install ROracle-0.5.5.

Solidot.org helped with MySQL encoding
Solidot.org is a chinese clone of famous Slashdot.org. It is my favorite site to read geek IT news. Yesterday I read a “help request” from solidot.org for experienced Linux server expert. They encountered a problem to restore the MySQL dump to the new server. It appears to be text encoding problem.
