Debian Buster: install and configure phpmyadmin

Required Apache2, Mysql/MariaDB,  and PHP 7.x

There is no phpmyadmin package in Debian 10 Buster Repository. You need to install it manually.

1. Create folder /usr/share/phpmyadmin/
2. Download phpmyadmin from https://www.phpmyadmin.net/downloads/ and extract into  /usr/share/phpmyadmin/. Note: phpMyAdmin version 4.9.1.
3. Create folder /etc/phpmyadmin/
4. Create a new config file from configuration using file config.sample.inc.php
   # cp /usr/share/phpmyadmin/config.sample.inc.php /etc/phpmyadmin/config.inc.php
5. Create folder /var/lib/phpmyadmin/tmp
   # mkdir /var/lib/phpmyadmin/tmp
6. Edit /etc/phpmyadmin/config.inc.php
   $cfg['blowfish_secret'] = 'ABCDEabcde1234567890ABCDEfghij12'; // random 32 characters
   ...
   /**
    * Directories for saving/loading files from server
    */
   $cfg['UploadDir'] = '/var/lib/phpmyadmin/tmp';
   $cfg['SaveDir'] = '/var/lib/phpmyadmin/tmp';
7. Create apache configuration file for phpmyadmin
   # touch /etc/apache2/conf-available/phpmyadmin.conf
8. Edit /etc/apache2/conf-available/phpmyadmin.conf, copy paste these lines.
   Alias /phpmyadmin /usr/share/phpmyadmin

9. Enabling your phpmyadmin config in apache2
   # a2enconf phpmyadmin
   Note to disable # a2disconf phpmyadmin
10. Reload/restart your apache2
    # systemctl reload apache2

Remove folder /usr/share/phpmyadmin/test/ and /usr/share/phpmyadmin/setup/. You can access your phpmyadmin using http://localhost/phpmyadmin.

If your mysql root (with password) can not login with error:
mysqli_real_connect(): (HY000/1698): Access denied for user 'root'@'localhost', do these:

1. using cli connect to mysql
   # mysql -u root -p
   Enter password:
2. Select mysql database
    > use mysql;
   Reading table information for completion of table and column names
   You can turn off this feature to get a quicker startup with -A
   
   Database changed
3. Change root plugin from unix_socket to mysql_native_password
   > update user set plugin='mysql_native_password' where user='root';
   Query OK, 1 row affected (1.372 sec)
   Rows matched: 1  Changed: 1  Warnings: 0
4. restart your mysql
   # systemctl restart mysql

If something goes wrong after you change unix_socket to mysql_native_password, revert it back.

Stop mysql server

# systemctl stop mysql

Start your mysql using mysqld_safe

# mysqld_safe --skip-grant-tables

In other terminal connect to mysql using root user

# mysql -u root
MariaDB [(none)]> user mysql;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'user mysql' at line 1
MariaDB [(none)]> use mysql
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed
MariaDB [mysql]> update user set plugin='unix_socket' where user='root';
\q


Now, You may kill your terminal where mysqld_safe running and start your mysql service normally.

Update date time using batch file

For dual OS, sometimes windows show date incorrect. You need to go setting and force windows to synchronize its date time.
The easy way and fast is using batch files. Using text editor, create batch files for example datesync.bat in your desktop. Write or copy/paste this code:

Echo off
Echo Starting Windows Time Service
net start w32time


Echo Syncronizing Date Time
w32tm /resync
pause

Everytime your date show incorrect, run this script as administrator. It will start windows time service (should not be disable on services.msc) and syncronize date time from internet.

Android Studio 3.5: Clone android project into new android project with diferent name

defender locking bignox virtual disk

windows defender sometimes open file in background process, to scan for malicious code. If defender (or other antivirus) open bignox virtual disk it will lock it and cause your emulator crash. You need to exclude virtual disk that used by bignox. Here are the steps you need to do:

1. Open your windows defender (or your antivirus)
2. Go to setting "Virus & thread protection settings"
3. in "Exclusions" click "Add or remove exclusions"
4. Click "Add an exclusion" and choose "File type"
5. in "Enter extension" box type "vmdk"
6. repeat step 4 for file type "vbox" and "vdi"

You may want to increase your emulator by excluding these files:

1. C:\Program Files (x86)\Bignox\BigNoxVM\RT\NoxVMSVC.exe
2. C:\Program Files (x86)\Nox\bin\Nox.exe

Codeigniter: query builder select, insert, update and delete

Query table:
        $this->result = $this->db->get('ca_brand',$mmax, 0);
        if ($this->result) {
            return true;
        } else {
            return false;
        }
Query table with like filter:
        $this->db->like('name', $keyword); // buildin mysql escape
        $this->result = $this->db->get('ca_brand',0, $mmax);
        if ($this->result) {
            return true;
        } else {
            return false;
        }
 Insert row in table:
        // buildin mysql escape character
        $data = array('name' => $name);
        $this->db->insert('ca_brand', $data); // return true on success

        $insert_id = $this->db->insert_id(); // get id

Update row in table for spesific id
        // buildin mysql escape character
        $id = intval($id);
        $data = array ('name' => $name);
        $this->db->where('id', $id);
        //$this->db->update('ca_brand',$data, "id = "$id ); // option 1
        $this->db->update('ca_brand',$data); // // option 2
        $numaffectedrow = $this->db->affected_rows(); // to get nummber affected row
 Delete row:
        $id = intval($id);
        $this->db->where('id', $id);
        $this->db->delete('ca_brand');
        $numaffectedrow = $this->db->affected_rows(); // to get nummber affected row

Php 7.2 and Codeigniter 3.1.10

Codeigniter: check mysql connection

To check error in mysql connection, we need to change ENVIRONMENT to Production. Here is the example:
    //define('ENVIRONMENT', isset($_SERVER['CI_ENV']) ? $_SERVER['CI_ENV'] : 'development');
    //define('ENVIRONMENT', isset($_SERVER['CI_ENV']) ? $_SERVER['CI_ENV'] : 'testing');
    define('ENVIRONMENT', isset($_SERVER['CI_ENV']) ? $_SERVER['CI_ENV'] : 'production');
There are two ways to catch error in our controller:
1. Using dblib
        $this->load->dbutil();
        if ($this->dbutil->database_exists('myca')) {
            // Connection ok
        } else {
            // Connection fail
        }
2. Checking error in db
        $this->load->database();
        $errhandle = $this->db->error();
        if ($errhandle['code']==0) {
            // Connection ok
        } else {
            // Connection fail
            // to dump error code var_dump( $this->db->error());
        }
Tested on PHP 7.2 and Codigniter 3.1.10

windows: kill process by id using cmd

The most old games do not run on Windows 10. For example Red Alert and GTA San Andreas. Those games require DirectPlay in Windows 10 (legacy feature.

Before you try your old games you need to run cmd in administrator mode. In case the game does not play properly, switch to cmd and stop the game.
