How to check your YouTube channel statistics and compare with other channels

If you want to know your YouTube channel statistics you can do that by means of youtube.com/analytics. But if you want to see YouTube channel statistics other than yours, you can do that using a website socialblade.com. It gives you the details of a channel that includes, Total Grade, subscriber rank, video view rank, and progress graph on different metrics, etc. It also gives you the details of monthly and yearly estimated AdSense earnings if your channel is enabled with Google AdSense.

Another feature of this site is, you can compare your channel with other channels. There is an option to see YouTube channels which are similar to my channel. This will help in improving your channel viewership by learning what others doing.


It also offers YouTube top charts on different metrics. Top 100 YouTube networks, top 10 YouTubers, top channels by counties, by categories like education, comedy, technology, film gaming, entertainment, etc.

How to implement Linux tail command in Perl

I have tried writing a Perl script to simulate Linux tail command - print last n lines from a file. This is one of the common interview questions in Perl. This can be extended to print selected lines of other Linux commands like head. It works perfectly fine.


print "\nImplements linux tail command in perl \n\n";

$file   =  $ARGV[0];
$n = $ARGV[1];
open(FILE, $file);
@arr = ;
close(FILE);
$length  = scalar(@arr);
$n = $length  - $n;

while($n<$length )
{
print $arr[$n];
$n =$n + 1;
}

Converting number into text - spellnumber excel function

It is often useful to have a function to convert numbers into words in Excel. It will be very handy in accounts. I have written an Excel macro to convert numbers into text. I have already created a macro which will convert a number in Indian system - that is ##,##,### format, to words. You can find it here 

Now I have come up with a macro which does the same thing with the western numbering system, that is 3 digits separation like ###,###,###. The dollar is used as currency, but it can be changed to any currency just by changing the text "Dollar". You can do that by finding replacing.

How to use it:
1. Download the Excel VBA macro module from here 

2. Open Excel 

3. Press Alt + F11 
    A window will open, it is called Visual Basic Editor aka VBA editor. 

4. In the VBA editor select Insert, Module. 
    A new module will be created at the left side pane, on the right side you can see a blank pane. Paste your code here 
    
    Or, alternatively, you can import the module directly
    
5. Save and go back to Excel by pressing Alt + F11

6. In the Excel worksheet, select Formula and them Insert. You will see a dialog with available functions.
    You have to browse to User Defined Functions to your macro by     name ConvertCurrencyToEnglish_spellnumber
    select and provide proper input 


Here is a video showing steps clearly
