My world of YouTube

We all are watching YouTube since its arrival. I too used it many days for latest videos. But since many days I have started subscribing to channels and follow them regularly. This blog contains information about some of the channels I prefer and follow regularly.  

Being post graduate in engineering I prefer watching videos related to science and technology. To name the few some of the channels are vsause, minute physics , minute earth, veritosim, smarter everyday, TEDed, TEDdirectors. Each channel has its own features which keeps me interested and makes me check it again. 

Vsauce and veritosim talk about different questions and technologies. Vsauce has touched on many philosophical questions also. There are vsauce 1,2,3 too. Minute physics as name suggests creates videos about physics. Smarter everyday also has videos for general interest. I have observed that all these people from different channels are connected to each other, use each other's knowledge and resources to make better and better videos. They take great efforts to make their videos to become better and informative. These all people create videos for layman. Anyone can come and started watching their videos from any time. 

Other channels I prefer watching are created by professionals TED is big organization which arranges talks from greatest people from all different technology, background and concepts to share their thoughts to world. TEDed is channel for educational animated videos. TEDdirectors is channels for clippings from different talks conducted all over the world. 

Both channels contains great must watch content. TEDdirectors contains list of most viewed videos of  different topics. 

We all spend some time checking something which can be utilized checking these greatest videos from different videos from different backgrounds but greatest thoughts and ideas of mankind. 

Testing computation power of RPi

To test computation power of computer we can we it for do some smart computation then verify it's speed. 

There is one other way to do that we know that video rendering and display takes lots of computation power and to test computer for its speed we can simply run some very heavy game or video. 

Instead of getting into programming and keeping time I tried running 1080p video on RPi. 6.34 GB size movie the matrix. 

Just to give you hint how much computation it did I will calculate bytes calculated per sec. 

Movie is 136min long that is 8160sec. 

6.34 GB is 6492 MB and after dividing by seconds it gives

0.795588 MB that is 815.68KB of content is processed per second that's too much as compared to RPi's capacity. 

6,673,876 operations per second, sounds amazing isn't it??

RPi is optimized with its GPU to perform very well with high graphical demand or fast computations. Because robotics needs lots of operations and very high speed. This GPU can be used to fast robotics computations or to watch 1080p HD videos. :)

Enjoy. Have a nice day. 

Introdution to Raspberry Pi

 

I am not a very good writer but I thought of creating a blog and keep track of things i am trying with everything.

Currently I am working on project  of Raspberry Pi (RPi). 

First and foremost question why Raspberry Pi?

I have a very old machine which has configuration lower than my iPhone. I was lying around for very long time without any use. To make use of that and my head I though of using it for some work which won't need anyone to take care of it and it should work mostly autonomously. There were few ideas of Home automation and home security system using simple webcams.
 It turned out that to use that machine I will have to use very low requirement software and some hardware programming which means I will have to work with USB which are not very developer friendly.

So after going through lots of option and doing good amount of study I decided to use very simple to program computer.

Raspberry Pi works on Linux which i am using for very long time for basic things. It is very popular with simple control simple electronic circuits with it.

I have been using 2 operating systems Xbian and Raspbian.

Xbian converts very small computer in to home theater  like using smart LED TV.

While Raspbian main OS used for RPi as it was mainly designed with hardware. It comes preloaded with things which you can think of doing with RPi you hardly have to install anything. This helped me using RPi without much trouble and i could get anything by just googling.

 What have people tried with RPi?

Everything!!

• Controlling lights, other electronic instruments.
• Robots.
• Weather study machine sent using hot air balloon.
• Sea study machine.
  
• Satellite. 
• Supercomputer.

List is too big to cover but  above list gives sufficent idea.

In next post I will  explain about what have I tried so far and what am I going to achieve with it.
