Download videos from youtube and various sites

Hi All,


Today i am going to share a tool which I liked most and easy to use. I was searching for a tool which can download videos easily from me. After thorough search, i found various utlities which are free or paid, but have some restrictions. Finally, I am satisfied with

“Youtube dl”, a command line utility where you can download videos from various sites, even playlist can downloaded easily.

Steps to use ( Windows )

  1. Download “youtube-dl” from
  2. Place the executable in some folder.
  3. Go to that folder from Command Prompt
  4. Then type this command – “youtube-dl [PATH]”

Here, [PATH] may be url for single video or playlist.

Enjoy downloading.!!

JS Channel session @The Capitol


Hi friends, yesterday was a very good day for me. I attended my first JS Channel session in Bangalore.

The session was divided into four talks.

First one was delivered by Autodesk people,  @arvindthangli and  @blrbalajiram.

The topic was Viewer API. With this, you can interact with the 3D models in the Web seamlessly without installing any plugin(Flash/Silverlight). So, you can use three.js for this. But, they created their own Wrapper for simplifying the work for developers. They have their own conversion algorithms ( in their server) for converting various file formats( they claim more than 50) to some “Neutral” file format which can be rendered very easily in web browser.

For more details, please visit this link  –

Second talk was delivered by Ritvvij, Founder of Pykih on Pykquery.

This talk was entirely based on Data Visualization. The graphs and data interactivity was amazing. You can learn more about this on their official site.

Third talk was delivered by Charanjit Singh on Funcational Reactive programming. you can presentation from here.

Fourth talk was delivered by Altanai Bisht on Web RTC and AR on Web.

Some of the random links I have collected :

Error 0x80070570 The file or directory is corrupter and unreadable

The above error I faced when I copying my files to F:\ local hard disk drive. (Windows 8.1)

The problem is the due to some errors in file system.

I solved it by simple command prompt command.

Run the command prompt with Administrator privileges. Execute following command chkdsk .

“chkdsk /f F:”

Then I tried copying to my F: Drive. it works like magic.
