Light Real flame with Smart phone - The Smart Candle

In this bleeding edge era, smart lighting is a thought to ponder over. LED bulbs are a little too modern, isn't it? Now you can have the classic and aesthetic glow of smart candles with the click of your smart phone.The company LuDela has broken the stereotype saying these are real candles, not the cheap looking LED stuff. You can really light flame using app.
This is believed to be made of beeswax and supports 30-hour lighting. The range starts from $100, with $20 additional charge for an extra shell (optional).

This innovative candle consists of 3 layers i.e. the outermost layer, purely artistic; the second layer is made of silicon device; the third layer is the candle (wax). The differentiation between the layers can be observed if watched carefully.LuDela lights the flame by channeling the heat between four electric nodes present around the wick. It has a fan near the wick which extinguishes the light. Other than this, many sensors are inbuilt which will help in preventing any hazard.

LuDela lights aim to avoid dangers of normal candles.The price may seem to be more then it should cost but for the people who hate hunting for matches and lighter, this technology may prove helpful. Personally, I liked the idea of lighting the candle with my phone. It can prove to be exciting for home automation.

Revealing Blockchain

Thinking of secure financial transactions but tired of processes like sin up, log in and remembering the password? Think of the time when manual transactions were done, replaced by online banking - a frog leap, isn't it? So, now the market is growing with Blockchain technology replacing financial institutions. Before discussion of  Blockchain ,Let us first try to understand Bitcoin which will help us in understanding Blockchain technology.

Bitcoin
Bitcoin is nothing but a virtual currency which is very easy, inexpensive and secure to deal in.It is an electronic currency which has no centralized controlling authority.The value of bitcoin fluctuates , it can be traded one to one or the way you like. Bitcoin, an innovative payment method, and open source software released in 2009 by Satoshi Nakamoto.

Blockchain
Blockchain is a distributed database technology which secretively keeps the record of each and every transaction done between buyer and seller. It doesn't require any intermediate source to process your payment. To understand this , let us consider the example suppose you want to buy a mobile phone from some shopping site . You allegedly need some intermediate to ensure your payment process which is a third party. This third party may or may not be reliable. So this problem is solved by blockchain, which ensures no third party interference.
Blockchain is a public ledger which is fault tolerant and highly secure. As the transactions are saved distributedly in millions of systems, it is almost impossible for hackers to hack the transactions.

Future of Blockchain

• Blockchain can be widely used in financial institutions as secure currency is what we all want.
• Small business can use blockchain for creating trusted trading platforms.
• Blockchain reduced cyber risks ensuring trusted transactional activity.
• The future of finance seems to be dominated by Bitcoin.
• Blockchain could also be implemented in elections and social welfare.

With the advent of technology, many new innovations have replaced stereotyped things. Let us see how far Blockchain goes...

Why most students choose to be an engineer in India

Pre-university becomes a challenge for most students as they are totally confused about which option  to choose as the career that provides financial stability as well as prestige at the same time.Every year approximately 15 lac engineers get the degree and only 30 % of them manage to get jobs that too in IT sector. The big question is 'Does India need so many engineers'? and 'What are the reasons for choosing mostly engineering as the career option'?

Let us look at some of them -

• Prestige Point-  In this global era, everybody craves for respect and luxury.Looking at the statistics one can judge engineering degree is successful in providing name and fame to students .An engineer is respected a lot in society, giving an opportunity to work with brand names like Google, Amazon , Microsoft and so on and this is one of the major reason why students go for engineering background.
• Parents Pressure- It may sound lame but a bitter truth where parents and relatives pressurize the students comparing them to neighbor's kid whose scores better in exams. Sometimes parents fail to recognize the capabilities and land up watching their kids struggle.
• Rat Race- It is true that the world is a rat race, everything is about competition. Reality lives far behind, Mirage and glamor have overtaken truth.Students themselves do not realize what they actually want and finally end up fighting cut throat competition.
• Lack of Awareness- According to Human Development Index , India stands on the rank of 130/187 in development , which justifies the lack of awareness prevailing in students. Most students don't recognize what they are interested in and the career choices available. So, finally end up in brainless herd race. 
• Extra option- Many of students think of engineering as a safe option to earn and if they don't succeed in their experimental startups or other career options then last option would be engineering job which will at least be able to fill their bellies and provide them a stable life.
• The POSITIVE one- The international survey of rankings reveals the number of people who are passionate about their work and would continue to work for the same engineering profile. The results are-

They were asked to rate their love for current engineering profile they are working on-

Love it and work for free- 18%

Hope for improvement- 35%

Like it for now- 25%

Hate it - 10%

Did not answer- 12%
