Unable to Create New User/Administrator in Magento 2.x

Yesterday, I tried creating an account from the Admin Panel but was unable to do so. After filling up all the fields in the User Creation Form and when I hit the Save Button, the screen would just get stuck with the rotating GIF image.

There are many causes to this issue but below I will discuss the one I experienced and how I resolved it.

The thing is, few days ago, I'd created a role called 'Store Owner' & assigned to it some permissions. Yesterday, I renamed the role to 'Store Manager' and assumed that like other CMS that I use viz. Drupal, changing the role name wouldn't revoke the erstwhile granted permission to the renamed role biz. 'Store Owner to Store Manager.'

Once I granted permission to the newly created role my problem was resolved.

Hope this helps!

Installing Google Cloud SDK for App Engine using Python 2.7 in Ubuntu 14.04

This tutorial shows you the various steps to successfully install the Google Cloud SDK for App Engine using Python 2.7 in Ubuntu 14.04.

1. First make sure whether you have Python 2.7 installed or not. Open your terminals and enter the following command:

 $ python -V  

You should similar output as this: Python 2.7.6.

2. Download the SDK for App Engine from here: http://bit.ly/2fe0azC. Make sure you select the Python version.

3. Once your file downloads, extract it in any folder of your choice. In our example we will extract it inside the Home directory. Your SDK path in side the home folder should be like:

 ~/google-cloud-sdk/bin  

Note: In Ubuntu ~ represent the Home directory.

4. Remain in your home folder (do not change directory to your SDK folder) and execute the following commands in your terminal.

 ./google-cloud-sdk/install.sh  

You should be getting the following result as shown in the image below:

5. You will be asked the following questions which you may respond as below:


5.1 To help improve the quality of this product, we collect anonymized usage data  and anonymized stacktraces when crashes are encountered.. You may choose to opt out of this collection now (by choosing 'N' at the below prompt), or at any  time in the future by running the following command:

gcloud config set disable_usage_reporting true

Do you want to help improve the Google Cloud SDK (Y/n)?  N

5.2. Modify profile to update your $PATH and enable shell command
completion? (Y/n)
?  Y

5.3. Enter a path to an rc file to update, or leave blank to use
[/home/evagabond/.bashrc]
: just leave blank and hit enter


Iniitialize SDK


Use the gcloud init command to perform several common SDK setup tasks. These include authorizing the SDK tools to access Google Cloud Platform using your user account credentials and setting up the default SDK configuration.

Once you run the initi command, your default browser will open up and you will be asked to sign into your google account. This will be the account connected to your App Engine and various Google Cloud related services. 

6.1. Open up another terminal and run the following command:

 gcloud init  

6.2 Accept the option to log in using your Google user account:

 To continue, you must log in. Would you like to log in (Y/n)? Y  

For further instructions on initialization you may go through the following Google Documentaiton: http://bit.ly/2gsZdrY

Installing App Engine:

 Once you have successfully performed the installations explained above, you can now install the App Engine by running the following command in your terminal (also refer image below). Make sure you are outside your SDK folder else the command wont execute.

 gcloud components install app-engine-go  



To run App Engin: 

 dev_appserver.py app.yaml

        [SOLVED] - Problem after Updating NVIDIA Drivers in Dell 5558 Laptop using Ubuntu 14.04

        Today I was recommended to update my NVIDIA drivers to its latest version nvidia-graphics-drivers-367 package. Once I updated and rebooted my Dell 5558 laptop, using Ubuntu 14.04 I experienced a blank login screen. After some Google searching I found out that probably the Unity Service had failed to load because of driver incompatibility issue.

        So the solution I figured out was to switch to terminal from the blank login screen; where I was unable to see nothing. Press CTRL+ALT+F2 to switch to Terminal. Then log into your account and hit the following command to remove the NVIDIA drivers completely from your system:

         sudo apt-get remove --purge nvidia-*  
        

        You should be getting a message as displayed in the image below:


        Confirm by pressing 'y or Y' to delete.

        Once deleted restart your computer and install the compatible driver version.

        In my case I had TimeShift installed which is a software that allows feature just like Windows Restore through which I restored my computer to the state just before it was updated.

        Updating PHP 5.5.x with PHP 5.6 or PHP 7.0 in Ubuntu 13.04, 14.04, 15.04

        After trying a couple of packages, settings and configuration, finally I seem to have found out a working solution:

        1. Update your PPA repository with the  PHP 5.6 package sources:

         sudo add-apt-repository ppa:ondrej/php
        

        Please note the repository is as stated above and not as:

         ppa:ondrej/php5-5.6 because this has been deprecated where the above PPA is a co-installable one, meaning you can install PHP 5.5, PHP 5.6 or PHP 7.0 as per your requirement.

        Press enter to confirm. If you come across any error then you will need to install python-software-properties first as shown below:

         sudo apt-get update  
         sudo apt-get install python-software-properties  
        

        2. Update

        Once again update your packages:

         sudo apt-get update  
        

        3. Install PHP 5.6 and its relevant mods:

         sudo apt-get install php5.6 php5.6-mbstring php5.6-mcrypt php5.6-mysql php5.6-xml   
         sudo apt-get install php7.0 # for PHP 7.0   
         sudo apt-get install php5.5 # for PHP 5.5   
        

        4. Disable PHP 5.5:

        Now this step is very important else you won't be able to use PHP 5.6. Even when you check your PHP version, it will still display as PHP 5.5. Follow the step below to disable PHP 5.5.

         sudo a2dismod php5  
        

        5. Enable PHP 5.6:

         sudo a2enmod php5.6  
        

        6. Restart Apache web server:

         sudo service apache2 restart  
        

        Note: New location of php.ini file in PHP 5.6:

        The location of php.ini fie is changed in PHP 5.6 unlike PHP 5.5 where it used to be located at '/etc/php5/apache2/php.ini'; the new location is at '/etc/php/5.6/apache2'

        [[Solved]] - How to Update Eclipse from Terminal or IDE in Ubuntu 12.04, 14.04, 15.04, 16.04

        Since I had installed Eclipse manually under '/opt/eclipse/' directory and not from the Ubuntu Software Centre, I couldn't update it from the terminal. Trying to Update Eclipse from the Terminal or within the IDE was giving me several errors such as these:

         Error 1:  
         An error occurred while uninstalling  
         session context was:(profile=epp.package.cpp, phase=org.eclipse.equinox.internal.p2.engine.phases.Uninstall, operand=[R]org.eclipse.platform_root 4.5.1.v20150904-0015 --> null, action=org.eclipse.equinox.internal.p2.touchpoint.natives.actions.CleanupzipAction).  
         Backup of file /opt/eclipse/.eclipseproduct failed.  
         File that was copied to backup could not be deleted: /opt/eclipse/.eclipseproduct 
         Error 2:  
         An error occurred while uninstalling  
         session context was:(profile=epp.package.cpp, phase=org.eclipse.equinox.internal.p2.engine.phases.Uninstall, operand=[R]org.eclipse.rcp_root 4.5.1.v20150904-0015 --> null, action=org.eclipse.equinox.internal.p2.touchpoint.natives.actions.CleanupzipAction).  
         Backup of file /opt/eclipse/readme/readme_eclipse.html failed.  
         File that was copied to backup could not be deleted: /opt/eclipse/readme/readme_eclipse.html 
         Error 3:  
         An error occurred while uninstalling  
         session context was:(profile=epp.package.cpp, phase=org.eclipse.equinox.internal.p2.engine.phases.Uninstall, operand=[R]org.eclipse.rcp_root 4.5.1.v20150904-0015 --> null, action=org.eclipse.equinox.internal.p2.touchpoint.natives.actions.CleanupzipAction).  
         Backup of file /opt/eclipse/readme failed.  
         Permission denied  
        

        Update Eclipse

        Looking at the above errors I figured out one of the possible cause was that Eclipse did not have SU (Super User) privilege. So, I executed Eclipse from the terminal giving it Super User privilege. And once in the IDE ran and update from within it. (Look image below)

        To run Eclipse with Super User Permission from within the terminal. Launch your terminal with CTRL + ALT + T:

         cd /opt/eclipse  
         sudo ./eclipse  
        

        Updating Eclipse from IDE

        Once in Eclipse go to Help > Check for Updates. Now the Eclipse should be updated without any error.

        JavaScript Equivalent of PHP's number_format() Function

        Today while going through JavaScript I came across a float value and then wanted to truncate it by two decimal places. I knew in PHP we have the number_format() function and this is what I found for Javascript:

        yourFloatVarHere.toFixed(2);

        Example:

        Suppose you have a value say: 0.589723, and you would like to truncate this value to two decimal place.
         var divide;  
         var num_format;  
         divide = 33/86;  
         num_format = divide.toFixed(2);  
        

        33/ 8 = 0.38372093
        Since we have truncated our answer to two decimal place, the final answer will be: 0.38

        Understanding the Difference Between isset(), empty(), is_empty() and unset() functions in PHP

        isset() function in PHP: 

        As the name suggests the isset() function in PHP checks whether the variable 'is set' or not. To be more clear this is what happens when this function is called:
        •  Checks whether the variable is declared or exists or set or not. It returns TRUE or 1 if the variable is not NULL, not an Empty String represented by '' or an Undeclared variable.

        empty() function in PHP: 

        The empty() function in PHP returns TRUE or 1 in the following cases:
        1. if the variable is undeclared
        2. if the variable is assigned zero. Example $high = 0;
        3.  if the variable is assigned an Empty string or declared NULL. Example: $high= ''; or $high = NULL;

        is_null() function in PHP:

        As the name suggests, the is_null() function checks whether a variable is NULL or not. This holds TRUE if:
        1. variable is not declared
        2. variable is declared as NULL. Example: $high = NULL;
        Note: '' empty string is not NULL.

          unset():  

          You can wipe a variable out of existence using unset().


          Handy Usage: These functions are handy when you need to make sure that the user filled out the appropriate fields in the form.

          Example:

           <?php   
            // Experimenting with isset(), empty() & is_null()   
           // Comment/Uncomment each condition below and test  
            // $high = '';   
            // $high = NULL;   
            // $high = 0;   
            // $high = 'hello';   
            echo '$high = '.$high.'<br />';   
            echo 'isset($high) = '.isset($high).'<br />';   
            echo 'empty($high) = '.empty($high).'<br />';   
            echo 'is_null($high) = '.is_null($high).'<br />';   
            ?>

          Note: The setup programs are 32-bit software. If you have a 64-bit system you may need to install libraries to allow your machine run 32-bit software. One way to do this is to run the command:

           sudo apt-get install lib32z1  
          

          2. If you have previously installed the App Inventor setup software, you should remove those files before installing the new software:

           sudo rm -rf /usr/google/appinventor  
           sudo rm -rf ~/.appinventor  
          


          3. Download the .deb package for the Emulator from the following link: http://appinv.us/aisetup_linux_deb

          4. Use the GDebi Package Installer to install the .deb Emulator package. If you don't have the GDebi Installer you can get it from the Ubuntu Software Centre at: http://bit.ly/2c1AlRD

          5. The software will be installed under /usr/google/appinventor.

          6. Hit Ctrl+Alt+T and fire up your Terminal and change directory as below:

           cd /usr/google/appinventor/commands-for-Appinventor  
          

          7. Once in the appInventor directory enter the following command to finally Run the Emulator:

           ./aiStarter  
          

          8. Now connect the appInventor to the Emulator as shown in the image below:

          What Should You Use, Kazam, Simple Screen Recorder or Vokoscreen for Screencast in Ubuntu/Linux?

          Top 3 Screen Recorder for Ubuntu/Linux:


          I tried all Kazamm, Simple Screen Recorder and Vokoscreen and this is what I would recommend:

           Kazam

           


          If you would want to go with a simple solution then go for Kazam. You simply install the software and sart using it without having to be bothered about much customizations.

          To Install Kazam: 


          You can install it from the Software Center by checking this link: Download Kazam.

           SimpleScreenRecorder

           

           

          SimpleScreenRecorder has much more features and customization compared to Kazam. For detailed configuration option for SimpleScreenRecorder, you may check my other post: SimpleScreenRecorder Configuration.

          To install SimpleScreenRecorder:


           sudo add-apt-repository ppa:maarten-baert/simplescreenrecorder  
           sudo apt-get update  
           sudo apt-get install simplescreenrecorder  
           # if you want to record 32-bit OpenGL applications on a 64-bit system:  
           sudo apt-get install simplescreenrecorder-lib:i386  
          

          Note for Audio setting: If you are  using a microphone, then please select the option: 'Built-in Audio Analogue Stereo' as shown in the image below.



          Vokoscreen

           



          Vikoscreen has similar features as SimpleScreenRecorder. The one feature it stands out from both of the above screen-recorders is it's Webcam option. If you select the 'Webcam' option then you can enable your webcam and simultaneously record yourself along with your screencast.

          Note for Audio setting: Same as above.

          Install Simple Screen Recorder in Ubuntu 14.04 with Settings Configuration

          Open your terminal by entering CTRL+ALT+T and enter the following commands:

           sudo add-apt-repository ppa:maarten-baert/simplescreenrecorder  
           sudo apt-get update  
           sudo apt-get install simplescreenrecorder  
          

          If you want to record 32-bit OpenGL applications on a 64-bit system:

           sudo apt-get install simplescreenrecorder-lib:i386  
          

          For technical settings and configuration, such as audio/video settings, please watch the video below:

          Redirecting a Naked Domain (non-www to www) to its WWW Version in Blogger/Blogspot

          The steps below explains the procedure to redirect your naked domain to it's 'www version' such as, 'example.com' to 'www.example.com' for blogspot.

          I also found an explanation in blogger at http://bit.ly/1TiXBis but that didn't help my case.

          So, goto your domain host such as Godaddy or Netfirms. Then open the section called as 'Domain Name System', 'DNS Management' or 'DNS' etc in your Domain Control Panel.

          Now look for a section called as Address Record aka 'A Record.'

          Then open your terminal or shell and ping your blog address as below:

           ping www.example.com  
          

          After pinging you should get an IP address as: '74.125.200.121'

          Copy/Paste this IP address and paste it in the Value box of your A Record as shown in the image below:


          Save and exit.

          It should work now else please allow sometime, a few hours and check again.

          Interpreters and Compilers Explained Simply

          Today while trying to recollect the difference between an Interpreter & a Compiler I ran across this classic Computer Science tutorial video series:


          Executing Java Program from Ubuntu Terminal

          If you want to execute your java program from your terminal in Ubuntu first make sure you have installed any one of the Java packages:
          • default-jdk
          • ecj
          • gcj-4.8-jdk
          • openjdk-7-jdk
          • gcj-4.6-jdk
          • openjdk-6-jdk
          To know the differences in each of the above packages, please follow this link: http://bit.ly/24FpTc9
            In my case I installed the first package using the following command:

             sudo apt-get install default-jdk  
            

            Now change your directory to the directory containing your Java Program(s). Once done hit the following command to execute your Java Program:

             javac FileName.java  
            

             java FileName

            Steps for Creating SSH Connection in Ubuntu 14.04

            1. First you should generate an SSH key pair on your Linux distribution. Open up your terminal and execute the following commands:

             user@localhost: ssh-keygen -t dsa  
            
             Generating public/private dsa key pair.  
            
             Enter file in which to save the key (/home/user/.ssh/id_dsa): (just press Enter here)  
            
             Enter passphrase (empty for no passphrase):  
            
             Enter same passphrase again:  
            Once you've entered the passphrase you will see the following message as below:
             Your identification has been saved in id_dsa.  
             Your public key has been saved in id_dsa.pub.  
             The key fingerprint is:  
             16:8e:e8:f2:1d:c9:b9:cf:43:9a:b3:3c:c1:1f:95:93 user@localhost  
            

            This will create a private key written to /home/user/.ssh/id_dsa and a public key written to /home/user/.ssh/id_dsa.pub. The passphrase is used to protect your key. You will be asked for it when you connect via SSH.

            2. If you are using cPanel then log into it and open the SSH section. Then open the file 'id_dsa.pub' in a text editor like Gedit. The file will be located at '/home/user/.ssh/id_dsa.pub.' The '.ssh' directory might be hidden so press 'CTRL+H' to view hidden files & folders. Select ALL & COPY the content of the file inside the box with the label 'Public Key (DSA only):' Look at the image below.



            3. Logging in to your Web Hosting account via SSH in Linux:

             user@localhost: ssh-add /home/user/.ssh/id_dsa  
            
             Enter passphrase for id_dsa:  
            
             Identity added: id_dsa (id_dsa)  
            

            (The passphrase is the same as the one you have set during the generation of the SSH key in Step 1).

            Then you should initiate an SSH connection:

            user@localhost: ssh USER@HOST_NAME -pPORT

            • USER - the user for which you want to establish the SSH connection; this will be the same username as the one you use to log in to your cPanel.
            • HOST_NAME (or IP address) - here you should enter the host/IP of the server to which you wish to connect (e.g. siteground300.com);
            • PORT - the port for the connection - here you should enter the port provided by your Web Host; try something like -p18765
            Press "Enter" and if everything has been set up properly, you will establish an SSH connection to your account.

            Updating PHP & MySQL in Ubuntu 14.04

            1. Updating PHP 5.5 to PHP 5.6

            To upgrade to a newer version of PHP 5.6 on Ubuntu 14.04, you can use Ondřej Surý's PPA. He is one of the Debian maintainers of the php5 package. Also not that this update will overwrite any change you made to your 'php.ini' files. So, I recommend you make a back up of your 'php.ini' file and later on you can use it as a reference file to make changes in your new 'php.ini' file.

            To add the PPA and upgrade your packages, run:

             sudo apt-get install software-properties-common  
             sudo add-apt-repository ppa:ondrej/php5-5.6  
             sudo apt-get update  
             sudo apt-get upgrade  
             sudo apt-get install php5  
            

            1. Updating MySQL 5.5 to MySQL 5.6

             step 1 : take a backup  
             mysqldump --lock-all-tables -u root -p --all-databases > dump.sql  
             step 2 : remove old mysql  
             sudo apt-get remove mysql-server  
             sudo apt-get autoremove  
             step 3 : install new version of mysql  
             sudo apt-get install mysql-client-5.6 mysql-client-core-5.6  
             sudo apt-get install mysql-server-5.6  
             step 4 : restore your data  
             mysql -u root -p < dump.sql  
            

            3. If error after logging into phpMyAdmin:

            If you happen to get an error as below:

            'Your PHP MySQL library version 5.5.46 differs from your MySQL server version 5.6.27.....'

            Run the following commands:

             sudo apt-get remove php5-mysql  
            

            You might have to reinstall your phpMyadmin.

            To reinstall phpMyadmin enter the following commands:

             sudo apt-get install phpmyadmin
