In case you need to reset admin password for a Joomla install, you can do this by simply updating database record.

$ mysql5 -h <database_hostname> -u <database_username> -p <database_name>
Enter password: <database_password>
mysql> show tables;
(...)
mysql> UPDATE <database_prefix>_users SET password='d2064d358136996bd22421584a7cb33e:trd7TvKHx6dMeoMmBVxYmg0vuXEA4199' WHERE username='admin';

This will use mysql5 commadline client to connect to a given database. You will see if tables are in place. Then you will update password hash of user admin to secret which equals:

d2064d358136996bd22421584a7cb33e:trd7TvKHx6dMeoMmBVxYmg0vuXEA4199

You can also use any other database client of your choice, DBeaver is also nice utility with graphical user interface.

You can obtain necessary database access information from configuration.php file accessed by ssh/ftp on a web server.

public $dbtype = 'mysqli';
public $host = '<database_hostname>';
public $user = '<database_username>';
public $password = '<database_password>';
public $db = '<database_name>';
public $dbprefix = '<database_prefix>';

If you want to dump/backup a database into local file, use mysqldump5:

mysqldump5 -h <database_hostname> -u <database_username> -p <database_name> > dumpfile.sql

If you want to restore a database from a local file, use mysql5:

mysql5 -h <database_hostname> -u <database_username> -p <database_name> < dumpfile.sql

If you wonder where did the power menu option to make a screenshot go in Android 4 – you need to long press Power + Volume Down buttons together :-)

Still I don’t know how to disable screen inside ongoing call when my Power button is assigned to end call, or how to end call when screen is locked and Power button is assigned to lock screen ;-) Design Fail or hidden solution somewhere there deep inside..? Apple simply use one button to end/diall call and separate mechanical switch to lock the device – simple functional and elegant.. but hey why Android does not use this solution as well, is “button switch pair” already patented by Apple? ;-)
