So he has his tasks cut-out. To win confidence of his village elders to start a hospital as his first priority and to heal himself of his past hurts by focusing on writing.Setting priorities gave him a sense of purpose.

Ramu is naturally an easy-going person.But he lost some of his originality during his stay in hostel.He was looking to regain his original-self by way of service to mankind and in particular service to his native village. One way he tries to get away from pain of not having done his duty is to immerse in writing.His idea of redemption is to get his works published.He also had his own doubts that writing is an escape route than actual redemption. He thought more about others for his own redemption than his own family.That backfired many a times and he did realized his folly only after receiving some very hard knocks in his life before he turned 21. He always felt that the deviation between what he is capable of and what he is presently doing is too large and unfair to him.But he did not have any idea about how to close the gap and how to live upto his full potential. Writing on the other hand proved therapeutic for his bruised mind.

Test everytime before you push to git even though the changes may be simple changes.This is a great tip to be a good programmer

Best practices while coding in 'C' language.

2022-01-08T06:44:00.003-08:00

1. how do you optimize 'c' code? Ans: 1. Reduce large 'if' or 'else'blocks.If you return anyway from 'if' condition, don't use 'else'. 2. don't use 'static' variables in embedded code.because they occupy ram for whole life time of system. 3.use 'switch' 'case' instead of if else whenever possible. I cannot give exact explanation.But it reduces unforeseen erros in implementation. 2.Some best practices in 'c' Ans: 1. Always implement proper error handling mechanisms.It will make program fail-safe. 2. Make sure to assign deallocated pointer to NULL after free. 3. put debug logs in failure conditions with error code logging. 4. don't use too many 'if','else' conditions. switch statements are better when handling multiple condition checks. 5. make sure to free allocated memory. 6. don't use magic numbers. use MACROS instead. All the Best.

IoT - The next big thing in technology

2022-01-08T06:43:00.001-08:00

Probably you may never heard or heard very little about the next big wave in Technology. The technology is called M2M(Machine-To-Machine) Communications/IoT. The CEOs named it as Internet of Every thing or Internet of Things to be short. So what is M2M? How does it work? M2M means your machines can communicate with each other while you can focus on your core work. Eg: Your car can communicate with the server of your insurance provider to give update about the health of your car and even your driving habits! Your refrigerator can detect if items are depleting in the fridge and order online to your supermarket to refill the food items. The lights in your home switches on automatically the moment you enter your home and not only that in case you forget to switch them off, you can switch off your lights from your mobile phone! So that means M2M has applications in wide ranging fields. Its uses are envisioned from Industrial automation to Home automation,transportation,Health to name a few. There are lot of interesting forums to know about latest in M2M applications.Join Linked in forums to see what is happening almost live about M2M/IoT. Go!Get your visa to fly on IoT applications.

Ramu is not emotionally prepared to tackle the opposition to his proposal.He understood full impact of naysayers only after coming into touch with the village soil. He had totally worked out thinking about possible opposition and is desperately in need of a solution that removes the burden off his brain and move forward with his dream. Meanwhile his grandmother called him for lunch.Ramu got some solace from his disturbing thoughts while having his lunch.

Ramu alwyas thought about pros of starting a hospital.First time it occurred to him that there can be 'cons' also for the same proposal.He may have to face stiff oppoisition from some of the villagers.But why?Why would anyone oppose building of a hospital for the common good?Because there are many who feel pain to give credit to where it is due.So is this young lad garners all the credit just because he is building a hospital?What about our stature?Won't we be questioned by villagers why we did not think of such a good project earlier?

Few old faces greeted him when he alighted the bus.He replied gently and smiled.He is feeling overjoyed to be able to see his home again where all the joyful moments of his childhood days returns to him whenever he sets foot in his home. He was affectionately treated by his grandmother who is residing with her unmarried daughter who is polio afflicted. He had his lunch and sat on the chair in the portico.He feels thrilled whenever he sits in that wooden chair.That is the chair where his father used to sit and resolved several disputes of the village.He got thrill all over his body on sitting in that chair. Now he began to think about his plans for his village.The foremost issue is ofcourse building a hospital. Then an old man came and greeted Ramu.Suddenly a thought occurred to Ramu.What is that thought?Why that thought inspired Ramu?

Ramu is feeling rejuvenated sitting in the bus that is bound for his native village.Although he had visited his village earlier many tmes,this village trip is special for him.He had visited the vilage as a care-free student all these years.But now he got an employment with a big firm,so he is visiting as an earning person this time. Ramu had many dreams for his tiny vilage of about 1500 people.The village never had a hospital.For even a small illness,they had to go to nearby bigger village or to the nearby town.He decided while he is studying time that, when he had money,he would build a hospital for the village with all the specialist doctors. He did not had any plan for his purpose.He is never a planning guy.He roughly had an idea about what he should do,but did not have clarity about how he should go about for his personal dream for his village. He lost in the thoughts about his dream(without a plan) for his village when the conductor shouted his village name indicating the bus has reached his village bus-stand. Ramu happily alighted from bus with his backpack.

Your Friend - ‘Laziness’ and the ‘Real You’

2021-05-09T11:22:00.009-07:00

Are you friend with the your friendly neighbourhood ‘Laziness’

If ever you want to achieve anything in life then get rid of Laziness.

Let’s face it. Do not give it any fancy name. By doing that you are hiding your enemy. A hidden enemy is far dangerous than the one you can see. So let's face it right in its face.

All our life, we embark on laziness and complaint, Oh ! Why my life is like this. That complain is still acceptable because at-least you are aware something is missing.

There is another set of people who are more comfortable in ‘Laziness’. Just lazy-in all day long doing nothing. Become a sack of potatoes. What a bliss…..they can afford it. Believe me there's no greatest curse than this. For Human Body is designed to be active and if you are not using it, you are damaging yourself.

Often, Those who are Lazy have no goal at all in their life.

Secondly those, who have a goal but struggle to achieve it. If this is where you fall into checkout, laziness could be one of the cause too.

Laziness can be Physical and Mental. The subject in question is both. However since everything begins in mind, let's talk about the latter first. Whenever you want to do something new it is very difficult particularly, in the beginning. Your mind refuses to think, to look for alternatives, to search for ways and means to achieve your goal. Simply, because your mind is in its “comfort zone” and refuses to come out of it. And all this happens without your involvement.

Believe me, this is how powerful your ‘Subconscious Mind’ is, For all the time it has been programmed to be comfortable. To Think differently now is new command and this is a data mis-match from the previous programming of 'Comfort Zone' resulting in Command Error. Because this so called Laziness is programmed in your subconscious by you previously.

If you ever want to get rid of it, that-is, if at all, you have a ‘Goal’ and are serious about it, you must consciously do it.

Think of how to reach the goal, visualise and affirm so strongly that it is recorded in your subconscious and you will start seeing results or even miracles for that matter. Reaching your Goal is easy and possible now. For, now you are opening new doors into the realm of possibility. “When you match your ability with positivity it becomes possibility”.

Exercise daily for without being physically active you cannot be mentally active. Your mind is not ready to absorb new data if your body is lumping through the day. Even doing daily domestic chores is helpful in keeping you active.
If laziness is your friend get rid of it.
You can shy away saying oh you don’t know how much I think. I always think so much and am never lazy.

Dear friend, your brain is already designed to think whether you want or not. On an average there are 60,000 thoughts generated in a day and 80% are Negative. So if you have to change it you have to consciously work for it.

To think means thinking of what you want, how to get that job done.

You were thinking as a child, as an adult and will continue to think through old age as well.

Human brain works for almost 7 minutes even after a person’s death. Isn't it amazing ?

So the point is not if you are thinking or not, but to think in the direction of your goal. Focusing your thoughts on what you want and what will make it happen and just do it.

Life is too precious to be wasted ‘because of this reason I cannot or could not do it’ Instead be the one ‘Despite of so many reasons, I achieved it.

That is when you have discovered the ‘Real You’

Good Luck !
