What is Blockchain?
Blockchain is a decentralized and distributed system with details of digital records of transactions. The digital based ledger records are often referred to as blocks. The blocks of individual records are linked together like a chain. Hence it is collectively referred to as a blockchain.
The blockchain was invented by Satoshi Nakamoto for public transaction of bitcoin cryptocurrency.
What does a Blockchain contain?
Blockchain contains information about data i.e. relevant information about transaction, hash which is a unique code for the block, previous blocks hash. The first block which does not have previous block’s hash is called Genesis block. This series of information inside a block helps in tracking the history and difficult to modify the blockchain records hence adds security.
How transactions are done in blockchain?
For a blockchain the decision of adding the transaction to the chain is done by consensus and not by a single administrator as incase of centralized system. The majority of computers connected in the network have to validate the transaction. Also data that is available on blockchain network cannot be deleted from all systems as everybody in the network holds copy of blockchain records.
Uses of blockchain?
In cryptocurrency like bitcoin blockchain technology is very useful. Bitcoin eliminates the need of middle layer of banks and helps in asset to asset transfer as it is without the conversion of currency values based on location.
In real estate, the use of blockchain eliminates the need of notary. The records of real estates buying and selling gets recorded in the blockchain.
In hospital management system blockchain is used to record patients relevant data for doctors to access.
What is hashtag ?
Hashtag! well most of us know any word that begins with the pound(#) sign is a hashtag. Technically speaking, hashtag is a metadata i.e. information about data that is being posted on a social media or microblogging platforms.
Why is there a crazy trend to use a hashtag ?
The microblogging platforms such as twitter limit the content length to 280 characters. So hashtag becomes a way of conveying the message using limited characters to the followers and audience, in general. The hashtag is a tagging that helps in referencing the content and acts as a keyword for content search and categorization of similar content. The hashtags can be informal combination of words to make it more catchy and make it viral and trending, that is the fun part of it 🙂
Companies and businesses have been using hashtags as a cool way of advertising and promoting their products and services. Most social media platforms such as instagram, twitter, facebook, linkedin, pinterest etc. provide hashtag support for posts and hashtag based search to catch attention of its audience and get views. So apart from searching for people, products, influencers, companies we can also search with keywords, phrases etc.
How hashtag came into existence ?
Hashtag was first proposed by Chris Messina in a tweet in the year 2007 on twitter platform. In the beginning, only twitter had the support for hashtag concept but gradually other social media platforms included hashtag looking at the emerging trend and usage by netizens.

The song I came to sing remains unsung to this day I have spent my days in stringing and in unstringing my instrument The time has not come true, the words have not been rightly set only there is the agony of wishing in my heart I have not seen his face, nor have I listened to his voice only I have heard his gentle footsteps from the road before my house But the lamp has not been lit and I cannot ask him into my house I live in the hope of meeting with him but this meeting is not yet *** Composed by Rabindranath Tagore***

The term was coined by web browser programmer who invented cookie Lou Montulli in the year 1994 while building an e-commerce website.
Why do we see the cookie banner pop up?
The reason why we see the cookie banner popping up recently across most websites is because of legal concerns in Europe and some other countries, the GDPR(General Data Privacy Regulation) requires that the cookie banners be displayed on website to let the users know that cookies are being used by the website.

What is digital footprint?
So, you are an active internet user. You have atleast one social media account and in some point of time have uploaded a photo, shared a video, have liked/commented on friend’s post. Also, the likes on a post, private chat messages, the online shopping search of your favourite brand etc. Aren’t these the activities we, as individual’s tend to do to be connected and engaged or in search of something online? In simple terms, all this content builds up what is called as digital footprint.
That means, digital footprint also referred as digital shadow is a content (text or audio or video) with a set of traceable digital activities of an individual on the digital devices or any internet platform. That is, the stuff what you leave behind when you use online services for online shopping, social networking etc.
Why should you be concerned about digital footprint?
Once you are logged into any website be it for online shopping or listening to a trending song, remember that web is secretly tracking all your actions allowing the targeted marketers to advertise exactly what products you have been browsing in you recent past. Also social media platforms often introduce new policies of usage that we may tend to accept just by clicking Accept/Ok button without actually reading the policies. User privacy is a concern.
All this data can be leaked to make a profit out of it for research in terms of marketing products and building it better for human convenience where a set of customers habits and user experience can be traced.
Can we avoid not being eavesdropped?
As suggested by one of my friend you may say as well, if privacy is a concern browse without login into websites, use browser’s incognito mode, clear browser history. That doesn’t solve the problem at base level as there is this loophole: every device has a unique IP address and uniquely the browsed content can be easily traced.

Growing up in a neighborhood that was with a mix of people with different religions and their respective culture brings back the vivid memories of today from the past, Christmas and the festivities that follow, the celebrations and preparations by young as well as old.
The kids were always excited about collecting items for Christmas tree, the crib, hut decoration, the list goes on with small statues of baby Jesus Christ, mother Mary, villagers, houses, dried grass, lighting, stars, shining balls, jingle bells and so on. Back then though, things were available readymade in the stores/market, unlike today, people believed in investing time in little things, call it a self-help or being self-reliant and satisfaction of doing their own decorations, however small or big. The afternoons a week before Christmas were spent mostly in the kitchen by women in preparing the sweet specialties with delicacies of mouth melting Dodol, Bebinca, the crispy Rose cookies, Kormolas etc.
Every locality had a group of zealous youngsters who hosted the celebrations which lasted till the new year and was open for public. The main attractions were the big hut with a unique scenery depicting Jesus’ birth and happiness all around, a big Star(bamboo stick make wrapped nicely with clean white cloth) with embossed “Wish you all a Merry Christmas” Christmas tree, big fat white Snow man, and an old man.
Most awaited daily evening game was the Housie(the game of numbers and luck), it could be bought as one ticket for two Rupees and three tickets for five Rupees. This game had two rounds, the first one was called “Jaldi Five”, which was over after calling out five random numbers from a glass jar and the next round went on till they got the winner. The last night that is the 31st December had special visitor Santa Claus, karol singing, games like treasure hunt and musical chair.
Here’s is to wishing all the readers a Merry Christmas! with these memoirs.
