Slack Dark Theme in Windows 10

I found where the ssb-interop file is. Here are the steps:

• Make sure Slack is not running/in the background. Navigate to C:\Users\USERNAME\AppData\Local\slack\app-4.0.0\resources
• Open app.asar as an archive via 7-zip. 7-zip cannot do this normally you will need an extension. I used Asar7z plugin. Download the plugin as zip and extract it in your 7-Zip installation directory under the "Formats" folder.
• Now you will be able to open the app.asar file using 7-Zip.
• In the archive, navigate to the /dist/ folder
• Search for ssb-interop.bundle.js and open it
• Append the usual CSS style you use. I personally add this:
  document.addEventListener('DOMContentLoaded', function() { $.ajax({ url: 'https://raw.githubusercontent.com/laCour/slack-night-mode/master/css/raw/black.css', success: function(css) { $("<style></style>").appendTo('head').html(css); } }); });
• Save the file. 7-Zip will prompt you if you want to update the archive, say yes of course
• Close 7-Zip. Now reopen Slack and enjoy the dark mode.

How to enable debug in java application?

To enable debugging in java applications add the jvm arguments,

For Java versions < 5.0 use the following Xdebug and Xrunjdwp args,

    -Xdebug
  -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8000

 The above options will work in version greater than JDK 5.0 but not recommended and will not be faster since it will run in interpreted mode instead of JIT, which will be slower.

For latest version you can use the following and the above jvm arguments to enable debugging,

    it is better to use the -agentlib:jdwp single option

    -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=8000

Ant script to run maven clean and maven install commands

Following is an useful ant script to run the frequent maven commands using the m2 plugin in eclipse,

  <target name="maven clean">
      <artifact:mvn mavenHome="${maven.home}" fork="true">
          <arg value="clean" />
      </artifact:mvn>
  </target>

  <target name="maven install">
      <artifact:mvn mavenHome="${maven.home}" fork="true">
          <arg value="install" />
      </artifact:mvn>
  </target>

  <target name="maven clean-install">
      <artifact:mvn mavenHome="${maven.home}" fork="true">
          <arg value="clean" />
          <arg value="install" />
      </artifact:mvn>
  </target>

This will be useful for projects using maven and ant as build tools.

How to get rid of mdi064.dll Windows startup error message?

---

Every morning I just start up my PC just to see a bunch of popups and malware dll's starting up. However I happened to clean up all of 'em except this loner "mdi064.dll",

The message read:
            "There was a problem starting          
              C:\User\%USERNAME%\AppData\Local\Temp\\mdi064.dll
              The specific module could not be found"

And I was really frustrated about this little popup and din't know how to get rid of it anyway. Some sites suggested that I download and run a full system scan of the free version of Malwarebytes. So, I want to know where these startup programs run from and I found the msconfig command to see the list of starup programs that start with Windows.

Some info about why this is a Malware:

•   The library "mdi064.dll" has been detected as malware by 8 anti-virus scanners.
•   It is automatically set to start up on every windows logon via the current user registry key 'tsiVideo'

Now, How to disable this item from starting up?.

     Windows key + R and type the run command "msconfig"

And press Enter key, and now you will see "System configuration utility" interface

Check for this "tsiVideo" Startup item and disable it(Remove the checkbox). This is the bugger which contains the startup link to the mdi064.dll file located at "C:\Users\admin\AppData\Local\Temp\\". Since its detected as a malware and deleted by your antivirus software, it will no longer be available at that location and shows the dll file is missing.

After disabling this item, restart the computer to take effect. And you will no longer see this weird popup again.

If you still facing this problem or if the above steps solved your problem please leave a comment. I'll be at your help anytime.

How I installed Android's Lollipop update on my Moto G2

I got a system update notification from the Motorola Notification Services on 3rd Feb 15(What better gift I can get on my birthday).

I clicked on the notification and the above displayed "New system software available". Tapped "Yes, I'm in" to download the update.

The update software is almost ready to install,

When the download is finished, tap on Install now. But please make sure you have at least 50% to 60% battery charge available so that you don't end up into any issues. If you don't have enough charge available on your phone just click "Later" and once your battery is sufficient you can install the update from System Update in Setting menu. You don't have to download it again. And you cannot make or receive phone call during the update process. I had exactly 50% charge while still in charge so I clicked on install now.

Once clicked on Install your phone restarts once the update is installed and the version is shown with the "Update complete" message. As you can see the recent apps section is smooth and line up one after another back to back.

Goto Settings -> About -> Android Version -> Tap 5 times,
The all new Android Lollipop version 5.0.2

Taste the flavour of Lollipop on your phone and enjoy playing with it coz I do.

How to generate a random String in Java

The following function can be used to create a random string.

 private String getRandomString(int len){
    final String AB = "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ";  
    Random rand = new Random();  
    StringBuilder sb = new StringBuilder(len);
    for(int i=0; i<len; i++)
         sb.append( AB.charAt( rand.nextInt(AB.length()) ) );  
    return sb.toString();  
 }

You can call this java utility method to generate a random String of the choice of your own length.

Syntax:

getRandomString(int length); 

Note:Here length is the parameter which accepts the integer type and generates and returns a length character String.

For example:
     This is how you use this utility method.

 String randomStr = getRandomString(4);

 String ranString = getRandomString(8); 

Sample output(s):

gY5C
79V6yy2x    

Recover files on pendrive that has been changed to shortcuts

Getting back to the topic, to recover your data (which is converted to shortcuts), just follow these simple steps:

• Connect your pen/flash/external drive to your computer.
• Go to My Computers and check what drive it is assigned for example F: or G: drive. Lets assume its G: (replace it with correct letter as applicable in your case).
• Click on “Start” –>”Run”–> type cmd and hit OK. This will start command prompt.
• Enter the following command and hit “Enter”.
  attrib -H -R -S /S /D G:\*.*
• Now check the pendrive for the files.
  

    If the above command doesn't work then use a third-party tools that you can find on the internet. One cool tool i found is Piriform's  Recuva.

    Recuva recovers files deleted from your Windows computer, Recycle Bin, digital camera card, Memory Sticks, or MP3 player. And notably it's free of cost. Post your comments if you found any helpful or better tools.

Step By Step Installing and Configuring PHP5 Apache2.2 and MySQL5.1

Step1: Apache installation and configuration

            After all the steps of this tutorial, we'll be able to host our web site on our PC running Windows.

Download

VC9 x86 Thread Safe: php-5.3.6-Win32-VC9-x86 (zip format only) Apache Http Server 2.2.19/2.2.17
MySQL 5.1.50

Apache 2.2.19 (or 2.2.17) Install.

Run the Apache installer package, "httpd-2.2.19-win32-x86-no_ssl.msi" or "httpd-2.2.17-win32-x86-no_ssl.msi"

Click Next.

In the "Server Information" dialog box, enter

     Network Domain: localhost
     Server Name : localhost
     Administrator's Email Address: admin@mycompany.com
     Leave the default setting of for All Users, on Port 80, as a Service as it is.
     Click "Next"

 Note: The installer uses the information you enter to create a default Apache configuration file for you. You can always go back and manually change these values in your configuration file if you change your mind later.

When asked about the Setup Type, select "Typical" and click "Next".

In the Destination Folder dialog, allow the installer to install to the default folder. So, just click "Next"

Finally click the "Install" button to allow the installer to set up Apache.

When it is done, click the "Finish" button.

Once Installation is complete, verify the installation by clicking on the Apache Icon in the taskbar (far left), as shown below.

 

You can also verify your installation of Apache by opening http://localhost/ in your browser. Or you can just type in "localhost" for the URL.
 

Congratulations for a successful installation of Apache. We still have to configure Apache, but we will do it in the later steps.

Step 2: PHP 5.3.6 installation and configuration


    Extract PHP package
    Now it's time to install PHP5. Open the zip file & extract all your files to C:\php. Navigate to C:\php

    Make php.ini file
    Rename php.ini-development to php.ini

    Edit the php.ini file
        Edit 1
        Find extension_dir = "./" and replace it with

extension_dir = "C:/php/ext"

        Edit 2
        We're going to uncomment by removing the ";" from the extension to activate it.

Here are the extensions to be uncommented.
Search for each one them and remove the semicolon ";"

    ;extension=php_gd2.dll

    ;extension=php_mbstring.dll

    ;extension=php_mysql.dll

    ;extension=php_mysqli.dll

The First extension enables the Image GD library of PHP.
The Second enables mbstring.
The Third and forth enables us to use MySQL database.
Save the php.ini file.

    Setup PHP Environment
    Let's setup the PATH environment variable.
    Start->Control Panel->System->Advanced System Settings
    then go to the Advanced tab, click on the Environmental Variables button,
    then scroll down in system variables to find PATH,
    Edit it Add C:\php;

    Restart the System
    You must reboot a windows system after setting the Path variable.
    If you move on past that point without rebooting apache may have trouble finding your MySQL extensions.
    Now we have PHP configured.

    Let's move on to configuring Apache.

Step3: Configuring Apache
Go to C:\Program Files (x86)\Apache Software Foundation\Apache2.2\conf\

You may need to turn off UAC for editing.

    httpd.conf Editing

Edit 1:

Uncomment:

#LoadModule rewrite_module modules/mod_rewrite.so

=>

LoadModule rewrite_module modules/mod_rewrite.so

Edit 2:

Add the following below the previous edit

#PHP5

LoadModule php5_module "C:/php/php5apache2_2.dll"

PHPIniDir "C:/php"

Edit 3:

Search for

AddType application/x-gzip .gz .tgz

Add the following lines below it. These lines define a MIME (Multipurpose Internet Mail Extensions) type for files ending with a file extension of .php and .phps so they will be processed by the PHP parser on request.

AddType application/x-httpd-php .php

AddType application/x-httpd-php-source .phps

Edit 4:

Search for DirectoryIndex index.html
Replace it with

DirectoryIndex index.html index.php

Edit 5:

Uncomment:

#Include conf/extra/httpd-vhosts.conf

=>

Include conf/extra/httpd-vhosts.conf 

    Virtual Hosting Setup (optional )

    You are about to make our server to host your domain for Apache Development project.  You can name your own but here I am going to use apache.dev as a domain name.  So, after we finished this step, we'll be able to type in our URL on the web browser:
    http://www.apache.dev/,
    then we get our home page from the http server installed on our machine.
    But we need to setup the directory structure to realize the Virtual Hosting.

Directory Tree Setup

Make directories:

C:/server/www/apache.dev/public_html

httpd-vhosts.conf Editing

Open the file in:

C:\Program Files (x86)\Apache Software Foundation\Apache2.2\conf\extra

Replace the contents with

<virtualhost *:80>

DocumentRoot "C:/server/www/apache.dev/public_html"

ServerName Apache.dev

ServerAlias www.apache.dev

<directory "C:/server/www/apache.dev/public_html">

AllowOverride All

Options Indexes FollowSymLinks

Order allow,deny

Allow from all

</directory>

</virtualhost>

Apache Webserver Restart

Let's restart Apache server and check if it restarted successfully.
.
Note: Configuring httpd-vhosts.conf is optional. You can place the php filesin httpdocs folder.

Testing PHP with Apache

In the previous step 3, we made directory structure, C:\server\www\apache.dev\public_html\. This is where you will be putting all your html and script files and our webserver will use those files.Let make a php file and name it index.php and put it inside the C:\server\www\apache.dev\public_html\ directory.

<?php phpinfo(); ?>

Then type http://localhost/index.php as URL for your browser. Then, you'll get the information about the PHP you've just installed.

Making Windows recognize http://www.apache.dev

This step is not necessary, but it's a nice feature to add. To make Windows recognize your domain on Apache webserver,  we need to edit hosts file in C:\Windows\System32\drivers\etc directory.

Add the following two lines to the hosts file.

127.0.0.1      apache.dev

127.0.0.1      www.apache.dev

Then type in apache.dev or www.apache.dev as an URL, then you'll get the same php information as when you type in localhost as an URL.
