How to use cell phone

I was recently watching TV show, this is what I have learned Using Cell Phone may cause brain tumor or other impacts.   But there is no proof at this time; the reason being latency between exposure and impact is at least 20 years.  The cell phone is being used only 16 years.

The amount of waves goes around our brain is equal to amount of waves using on Microwave oven.

You can protect by using wired earpiece, Don’t talk when your signal is really week that is the time more amount of waves being used to get you the signal, third don’t let kids talk on the cell phone, because the skull for them is much thinner.

InnoDB: table %s/%s: unknown table type 33

Filed under: MySQL,Xtrabackup — mani @ 11:21 pm

Ran into issue while restoring and recovering using xtrabackup.  innobackupex-1.5.1 –apply-log ./

130107 20:32:49 InnoDB: table bac002/_user: unknown table type 33
130107 20:32:49 InnoDB: table bac002/_user: unknown table type 33

InnoDB: Failing assertion: len % DATA_NEW_ORDER_NULL_TYPE_BUF_SIZE <= 1
InnoDB: We intentionally generate a memory trap.
InnoDB: Submit a detailed bug report to

InnoDB: immediately after the mysqld startup, there may be
InnoDB: corruption in the InnoDB tablespace. Please refer to
InnoDB: about forcing recovery.
innobackupex-1.5.1: Error:
innobackupex-1.5.1: ibbackup failed at /usr/bin/innobackupex-1.5.1 line 464.


I was using incorrect my.cnf file,  in my case I had incorrect binlog-format, and few other parameter.  Once I fixed them then restore/recovery worked just fine.
