Photography while travelling

Most of us love to travel. Travelling around the globe will be the ambition of many. I also love it and more over I love to take photos while travelling. Not of mine, ;) or selfies but the scenes which we have seen. They remind us all the things happened in our journey. Greatest moments with friends, incredible views of nature, sun set, clouds, beauty of flowing rivers etc. While remembering these, we actually will get refreshment and feel to such an extent that we will think the journey was on the previous day. The below image was taken by me while travelling from Quilon to Calicut by train (about 330+ km).

Quilon and calicut are two main towns of kerala, God's own country. My college is situated in quilon and my home is near calicut so this journey was not new one for me as I usually do once in every month but the thing is, in my last journey, I didn't give the rest for my camera option of my smartphone. I have taken most of the scenes through window of the train. I'm not a professional photographer at all but I love to take photos and I believe that there is a photographer's mind in everyone. Later when I look at the photos which I have taken, I have got an awesome feel which can't be described by words. Taking photos will be a hobby of many but giving some seriousness and imparting selective nature will change the scenario.

    

The above image was also taken by me when I have gone to korome village which is in wayanad district of kerala. Believe me you will never ever forget this place. Specialities are calm atmosphere, awesome weather condition, mix of different cultures, natural beauty, good number of places for tourism etc. I have taken this image of bamboo just before the rain that is why the sky looks like dark. The images which I have taken remind me many things and give me some kind of happiness even now. So keep your camera on and get the feel. Best wishes. 

How to increase the speed of computer?

Here I explain the different ways to increase the speed of computer (windows 8.1).

First thing you want to do is disable screen saver as follows.

1. Right click on desktop.

2. Click on personalize.

3. Click on screen saver (bottom right corner).

4. Select none from the list of screen savers.

5. Click Apply and then OK.

Then disable start up apps as follows.

1. Move mouse pointer to up right corner and select the search icon.

2. Type task manager and click on task manager.

3. Select start up menu.

4. Now you can see start up apps. Just click the unwanted apps and click on Disable button (bottom right).

You can increase your performance by adjusting power option by following the given steps.

1. Take search field as done earlier and type power option in the field. Click on power option.

2. Choose high performance option.

You can clean the junk files in the c drive by Disk clean up utility. For this follow the given procedure.

1. Select local disk c. Right click. Then select properties.

2. Click on disk clean up button.

3. You can check on check boxes of all items listed. Then click OK.

This process will not delete any personal data. This process deletes junk files only.

There are lots of animations while we are in front of our computers. Actually in performance point of view, they are useless. So disable animations as follows.

1. Select this PC (my computer). Right click. Then select properties.

2. Click on advanced system settings.

3. Select advanced menu. Then in performance section, click on settings button.

4. Select visual effects menu. Choose adjust for best performance option.

5. You can also change this settings according to your choice. Then click on apply then OK.

For more, defragment and optimize drives as follows.

1. Take search field and type Defragment and select the option.

2. Select each drive and click on analyse button and optimize button.

You can clean unnecessary temporary files through the following method.

1. Move mouse pointer towards the windows icon (bottom left corner).

2. Right click and select run.

3. Type %temp% on open field as shown. Then click OK.

4. Select all. Right click. Select delete option.

5. Again take run window as done before. Type temp. Click OK.

6. Select all. Right click. Select delete option.

7. Again take run window. Type prefetch in open field. Click OK.

8. Click continue.

9. Select all and delete them.

Now let's try some Registry tweaks.

1. Take run window. Type regedit in open field as shown. Click OK.

2. Select control panel. Select mouse. Then select mouse hover time. Right click. Select modify field.

3. Type small number. 10 is preferred. Then click OK.

4. Select control panel again. Select desktop. Select menu show delay. Right click. Click modify.

5. Type 10 in value data field.

At last restart the computer.

How much blessed we are ?!!

One week ago, I was travelling by bus. 10 minutes travel. There is a reason for sharing my experience with you right now. There would be almost 35+ passengers in that bus. Some of them were talking each other, some of them were doing nothing and some of them were dreaming. ;).

At that time, a new passenger came. The conductor who gives bus tickets helped him to climb foot path and ensured that he got his seat. I thought why he helped the new one. Then I realized that he was blind! Yes, can you imagine that what would be your life if you were blind?! Can you imagine?  You don't like that life, right? No sun, no moon, no sky, no birds, nothing...totally darkness..! Even you can't see your mother, father!!! Also you will be unable to see yourself..! What would be that life? Yes, such a life is lead by them, Blinds. So think how much blessed we are. We can see ourselves; we can see our mother, father, relatives, trees, sun, moon, sky etc. Thank your Lord who has created you. Then, we can return to my travel.

Bus is started. After 5 minutes, one person has entered the bus. Remember that, that bus was local bus. The new one's height was too low. Even he couldn't balance his own body! Again, the conductor helped him to be seated. I have seen many persons before who has no sufficient height but a man who can't balance his own body...?! It was the 1st time in my life. Again we want to think about our life, our height, our skills, our talents, our abilities. Yes, we are so blessed!

Again after 3 minutes, one person left the bus. He had a problem with his legs. His right leg was not good. But he was one of the people who continuously spoke during travel. Said jokes. But he has too a big problem. We want to think about our legs. So good! right?  Then thank your Lord.

Realize that there are so many people like this around you. They don't want Lamborghini car! They don't want royal Enfield bullet bikes. They don't want 10kg gold. Also they don't need those things. There is one thing above them all. What is that?  Love, compassion and unconditional love for the sake of our Lord. Love them. Mind them. Honor them. Don't ignore them.

What is Pre Ignition in SI engine ?

Do you know, some parts of engine like spark plugs, exhaust valves etc. have very high temperature, around 973 K before the end of compression stroke. Further, carbon particles will be deposited in various parts of engine due to incomplete combustion. These carbon particles also have very high temperature. These overheated things will cause a pre-mature combustion even before spark application. This pre-mature combustion before the application of spark is generally called pre ignition.

Then what will happen when spark is applied after pre ignition ?

When spark is applied, then there will be multiple flame fronts and it will increase the rate of pressure and decrease power output.

Due to pre ignition, more work is needed for compression so that there is a tendency for mechanical damages such as crank failure. Also it increases the chance of detonation and knocking. Then we can conclude that this is a serious problem and major type of abnormal combustion.
