Perl warning Setting locale failed in Ubuntu

Perl Locale Warning.
The warnings could be irritating, especially when installing any application. The warnings are also visible when some commands are run

The warnings look like:
perl: warning: Falling back to the standard locale ("C").
locale: Cannot set LC_ALL to default locale: No such file or directory
 
and when you run Run locale from the commandline

bonkhi@sparda-coven:$ locale

locale: Cannot set LC_ALL to default locale: No such file or directory

LC_CTYPE="en_US.UTF-8"

LC_NUMERIC=en_NG.UTF-8

LC_TIME=en_NG.UTF-8

LC_COLLATE="en_US.UTF-8"

LC_ADDRESS=en_NG.UTF-8

LC_TELEPHONE=en_NG.UTF-8

LC_MEASUREMENT=en_NG.UTF-8

LC_IDENTIFICATION=en_NG.UTF-8

LC_ALL=

To solve this, generate the missing locale

locale-gen en_US.UTF-8

Set the missing locale

export LANGUAGE=en_US.UTF-8
export LANG=en_US.UTF-8
export LC_ALL=en_US.UTF-8
locale-gen en_US.UTF-8
dpkg-reconfigure locales

How do you reset the circuit protection on Yamaha RX-v373?

Yamaha RX-V373 AV receiver's protection circuity is activated when there is fluctuation in power three (3) consecutive times. This protection mode disables the capability to "turn on" the device.

To disable this:

Hold "Info + Tone Control + Straight" for at least five seconds, while still holding, press the "Power" button.

Manually reboot the AVR for normal operation.

Restore crashed Windows 7 (with no recovery image) after installing Ubuntu

Have you tried dual booting Ubuntu and Windows 7 and windows fails?

Did the Ubuntu installation complete successfully, and grub was properly installed but you still get the blue screen of death when you try booting windows?

Well, this is simple. The answer is with the file type of the windows partition.

I am assuming you have set up Ubuntu and grub is correctly installed. If not, please see https://help.ubuntu.com/community/Boot-Repair#A1st_option_:_get_a_CD_including_Boot-Repair for more information.

To correct this, boot your system to the Linux installation and run in root:

fdisk -l /dev/xxx

The Id for the windows partition (sda1 & sda2) is 42 which is the code for SFS. Change the file type Id to 7, which corresponds to HPFS/NTFS/exFAT, save and reboot.

fdisk /dev/xxx
In the prompt, type p to print the current partition table

To change the file type, type t in the prompt and enter the partition to change.

In my case, I will enter 1. 

For a list of the Hex code list of the file types, enter L in the prompt.

Enter 7 in the prompt, which corresponds to the HPFS/NTFS/exFAT file system.

Repeat the process for the second or third windows partition, and when done enter w in to save.

Reboot your system, and grub will load windows ! !  !

Install Solaris, Apache, Mysql & Php (SAMP)

You may be conversant with the terms LAMP and WAMP. This means a stack of applications.

For LAMP = Linux, Apache, Mysql and Php/Perl/Python.
For WAMP = Windows, Apache, Mysql and Php/Perl/Python.

To get your new Solaris 11 installation SAMP ready, we need to install Apache, Mysql and Php.

kilo@kilo:~$ sudo -s
Password:
root@kilo:/home/kilo#
root@kilo:/home/kilo# pkg refresh
root@kilo:/home/kilo# pkg install amp
               Packages to install:    12
           Create boot environment:    No
               Services to restart:     1
DOWNLOAD                                  PKGS       FILES    XFER (MB)
database/mysql-51                         3/12     554/729    59.0/75.2


When done, enable the apache and mysql service.
root@kilo:/home/kilo#svcadm enable apache22
root@kilo:/home/kilo#svcadm enable mysql

By default, the mysql root user has no password.
root@kilo:/home/kilo# mysql -u root

Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 4
Server version: 5.1.37 Source distribution

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql>;


We can set the password for the root user in mysql using

root@kilo:/home/kilo#mysqladmin -u root password "PASSWORD"

If you get the error - 

bash: mysqladmin: command not found

It means that the command mysqladmin is not in the path.
root@kilo:/home/kilo# which mysqladmin
which: no mysqladmin in (/usr/gnu/bin:/usr/bin:/usr/sbin:/sbin)
 
To solve this, use the full path for the command.
root@kilo:/home/kilo# find / -name mysqladmin
/usr/mysql/5.1/bin/sparcv9/mysqladmin
/usr/mysql/5.1/bin/mysqladmin

/usr/mysql/5.1/bin/mysqladmin -u root password "PASSWORD"

Configure pkg in Solaris to use proxy

To configure your Solaris image packaging retrieval client (pkg) to use proxy -

kilo@kilo:~$ sudo -s   (I am using solaris 11. su - root can also be used)
Password:
root@kilo:/home/kilo# 
root@kilo:/home/kilo#export http_proxy=”http://proxyusername:proxypassword@proxyservername:port”

Replace the following -
proxyusername = your proxy account username
proxypassword = your proxy account password
proxyservername = your proxy server address
port = proxy port number
