Caesar Cipher

After having done a couple of posts on the Blockchain technology for the A2Z Blogchatter challenge, I have resumed my writing in the Information security field and a fun cipher called the ‘Caesar cipher’. But before we see what is Caesar cipher, let us have a brief understanding of Cryptography.

From time immemorial, we are trying to make sure that important and crucial information is readable only by the right people once it has reached its destination. What if a crucial message falls into wrong hands and is read by them? This is prevented by making use of Cryptography and its various strategies.There are a number of ways(or technically called ‘ciphers’) to hide a message and the Caesar cipher is just one of them. This is done by encoding(converting to a special form) the information to be sent at the sender’s end and decoding(re-converting to original form) the information on the receiver’s end.

What is ‘Blockchain’?

Blockchain is the distributed, shared ledger system with no central authority. We have all encountered ledgers in our lives. We have our own personal ledgers for keeping track of transactions. But in the case of a large business scenario, the number of transactions is huge. The number of people keeping track of those very transactions is huge too. Each person involved in the business might have their own version of transactions. Blockchain solves this problem by each ‘node’ having their own copy of the ledger.

Asset

The Blogchatter A to Z has kicked off and I start off my set of posts primarily around the theme of technical and personal posts. My latest fascination has been ‘Blockchain’ and I am striving to do my technical posts around my latest interest. 

‘Blockchain’ is the common shared digital ledger that every participant in the business sees. In the Blockchain world, any thing that has value is  called as an ‘Asset’. Assets are sold and bought and these are recorded on the Blockchain ledger. Asset is the key aspect of Blockchain. 

Assets are further classified into tangible assets and intangible assets. Tangible assets are those that can be seen and visualized. Examples of tangible assets are car, motorcycle, house.

Intangible assets are those that are abstract and cannot be seen but they play an equally vital part in the blockchain  cosmos. Examples of intangible assets are mortgage, patent, trademark. 

Cash is yet another form of ‘asset’ but it is completely anonymous. We cannot track its movements. We don’t know who we received it from and where it will go next. 

We discussed ‘Asset’ in the Blockchain world. Drop by tomorrow as I continue my ‘Blockchain’ journey…

Blockchain trainings!

Technology is a fickle thing. The requirements change at the speed of light!(not exactly – but fast enough! :))  No sooner do we think that “Java” is the most required skill in the technology space, in comes,  “Data analytics”, “Security” and “PMP”!!

Now it is artificial intelligence(AI), machine learning and the Blockchain wave that is sweeping the technology landscape and we hear that there will(or there already is) a shortage of professionals in these areas.  This results in organizations and professionals scampering to reskill in these areas and looking for appropriate trainings. This post will list the popular Blockchain trainings around Bangalore, India and around the world.

Why I don’t have a cooking blog?

It was just around 12:00 noon on a Sunday afternoon, and she was doing her homework in her room with full enthusiasm. She had Math, Physics worksheets to complete and she was constantly having doubts about how to solve the mysterious problems. She would run to her brother to solve all her problems. He was her “demi-god” who knew the answers to all her questions. 

Suddenly, a beautiful smell seemed to be emanating from the kitchen(or so, she thought) She knew her mom was cooking lunch and there had to be some non-vegetarian dish, since it was a Sunday. What was it? She would soon know… and she continued studying. 

Finally, it was lunch time. As she sat down to eat, she was given some rice and some gravy was poured on it. She took one mouthful of it and as her mother looked at her eagerly for compliments – she exclaimed that “It tastes like spicy fish rasam,amma!! :)” All her mother’s dreams of getting good grades from her daughter went down the drain as “meen kozhumbu”(fish tangy gravy) was renamed as “spicy rasam” – which basically means that the gravy was too runny and watery!!

She had just turned 10 then, and …. as the days rolled by, every dish received critical comments.

  1. The one glass of milk that she had to have in the morning – could neither be too hot nor too cold. It had be the perfect temperature with the correct amount of sugar and health mixes.
  2. Idli was her favorite and it needed the perfect accompaniment like ‘sambar’. The sambar needed the correct amount of tanginess and taste. Unfortunately for the daughter, the mother found cooking to be a chore and one that she wanted to be done with for the day as quickly as possible! (But does that ever happen with four people in a house?!!) 
  3. Lunch had to be tasty and the gravies that her mother made were expected to be to perfection.The mother always added a lesser amount of salt marring the dish, once too often! πŸ™‚ And boy , was she not pleased!!
  4. Sending lunch to school was a different ball game altogether. The menu had to be chosen such that they were filling – yet tasty and retained their original appearance by lunch time.  Normally when the lunch was packed in the morning(usually, some variety rice) it had solidified by the afternoon!! The daughter would dig her spoon right into the tiffin box – only to get a big blog of rice stuck together!! (Yuck!!)

   In summary, Idli, noodles, pasta and biriyanis were her favorite foods. Dosa had to be crispy. Chappathis had to be the perfect circle shape(which the mother had never mastered! :)) Rajma chawal was ruled out as it did not have taste. Egg rice was too dry. 

Now coming to biriyanis – she loved biriyanis. The biriyani should not be too sticky and they needed the perfect amount of spice! The  biriyani from each restaurant was greatly analyzed. Was ‘Biriyani zone’ better or was it ‘Paradise’? She felt that meat marinated in some restaurants were better than the others. Had the mother mastered the biriyani that she wanted? The daughter thought so…(thankfully! :))

The daughter’s taste buds were in stark contrast to the mother. Where did the daughter get such smart taste buds from, she wondered? Had she inherited it from her grandfathers?

Only when she satisfies the food critic in her house, did the mother think that she will venture into food recipes… until then….it will be the technical blogs which the mother hopes she has mastered! πŸ™‚

Pinkathon 2018!

What began as a gentle whisper in our community, soon reached dizzying heights as more and more ladies joined in to run the Pinkathon on February 18, 2018, in Bengaluru, India. 

For the uninitiated, ‘Pinkathon’ is the run founded by Milind Soman and Reema Sanghavi specifically for women, primarily to give importance to women’s health issues particularly, breast cancer. It encourages women to lead a healthy life by running and doing other physical activities.

Get shopping with ‘BigBasket‘!! 

January 2018:

It was just about a month back that one of our “Pinkies” decided that she was planning to run the Pinkathon and was preparing for the same. I was always a bystander in earlier marathons and acted only as a cheerleader! πŸ™‚ I never imagined I would want to do it and neither did many of us “pink sisters” in our community. 

But slowly, but surely, more and more people signed up to do the marathon. I also finally signed up though I never thought I would have the motivation to do it. Motherhood had made me rusty and I was not too much of a fitness freak except for my slow paced walks daily. We were finally a grand total of 22 ladies who had signed up for the run. 

But once we signed up, the positive energy rubbed off on all of us! πŸ™‚  We encouraged each other for daily practice sessions. I also tried a new fitness app(never a fan of all these digital devices that track every breath of your life)  to keep track of my daily walks and calories. New shoes were bought, appropriate apparel was chosen for the D-Day.  Our whole community wore a fitness look and one could see women jogging or doing a brisk walk everyday!

For many of us, it was the first “marathon” in our life! There were 3K, 5K, 10K and 21K runs. Most of us newbie marathoners, chose 3K – not knowing how exactly it would be.There were the healthy stalwarts who chose 5K and 10K too! πŸ™‚

Will I be able to do it was the big question tingling in my head?! (3K is actually not much of a distance – even if you “brisk” walk the distance – we can complete it in 30 minutes)  But still doing it in a marathon setting is a different experience. And the thought of getting up at 3:30 in the morning for the 6:00 a.m. run was more grueling than the run itself!! πŸ™‚

February 18, 2018:

The big day was here and as I woke up at the grueling time( a big thing for a night owl like me!! :))  all pumped up and excited !! All of us traveled to Kanteerava stadium and it was amazing to see the electricity in the stadium. There were 11,000 women eager to lead a healthy lifestyle and running was just a starting point! The day started off with some Zumba to loosen up the muscles. I do not remember swaying to any of the moves as I just wanted to get started with my run/walk! πŸ™‚

At approximately 7:15 a.m., we , the 3kers zoomed off with great gusto and enthusiasm! My 3K was more of walk than a run(did not want to take any risks there!) and most of us were done by 7:50 a.m. The run was amazing in that it had women from all ages. One could see the determined young mothers with their babies, elderly ladies,sari clad women, ‘madisar’ clad women amongst us.There were runs for the visually impaired as well. 

It was a fantastic experience for all of us and a week post the marathon we are still pursuing our fitness adventure! The experience empowered all of us – who went from  “Can we could do it?” to ‘Yes – we could do it”!! πŸ™‚

Cheers to the all the Pinkies in my community to make this happen! πŸ™‚

Use cases of Blockchain

Even as the concept of ‘Blockchain’ is bouncing off everyone’s radar and everyone is keen to know more about this trending topic – let us see more about this new and emerging technology. 

Introduction:

‘Blockchain’ is popularly associated with ‘Bitcoin’ cryptocurrency. The Blockchain system shot into prominence and more industry experts took notice of it only after Bitcoin’s surge and ultimately its downfall!

‘Blockchain’ as you might recollect from my earlier post is the shared ledger system. Each transaction is recorded and added to the shared ledger after being approved by the ‘miners’.  The beauty of ‘Blockchain’ is that each miner or node has a copy of the transaction. None of the transactions can be modified or deleted.It allows total transparency of the system with no central authority and promises complete anonymity and security.

Why does each state of India have a separate language?

Well, almost, each state…

And sometimes, I feel like I am answering questions on Quora… πŸ™‚ but I love to find answers for questions like these.

Now let us try to answer the question, first though some introduction. Each of the four(or is it five states, now?) southern states of India – Tamil Nadu, Kerala, Andhra Pradesh, Telangana and Karnataka each have a separate language and there are other local dialects too… (amazing, isn’t it?! :))The Northern states mostly adhere to Hindi. The western state of Gujarat has Gujarati as its language and the eastern states of India have their own languages (Assamese, Bengali etc) India is stated to home to 23 official languages and another 1650 languages!! (can you imagine?)

India might be the only country in the world or one of the few countries that has so many languages. No sooner do we drive 5-6 hours(roughly – not perfect here) in India , are we in another state with a different language and entirely different customs and traditions. 

 

But how did so many languages come into existence in India? 

India is an old country with rich traditions and customs. It is shaped by a beautiful history from the Mughal empire, Ashoka empire, Hoysala empire and so on.  As each dynasty left, they carved out beautiful traditions and new languages. It mixed with local languages and new dialects must have been born. This might have passed down generations and ultimately that became the language of a particular area of land… till a new dynasty came to power. This is my thought to this question – what is yours?

The reason that the languages stayed for so many years and it is still living:

The only answer that came to my mind was that we could not move as much(new forms of transportation like cars, bikes, boats, air travel have been achieved only of late) – so the languages that mushroomed stayed where they were. Moving from one place to another is a chore even in this day and age – imagine how it would have been several years ago. 

So, if Tamil was spoken in the state of Tamil Nadu and if people could not move much, they stayed there and propagated the language there alone. The same might be the case for other languages too. This has been continuing till date and the beautiful languages of India have stayed, grown and have continued to embellish our lives!

Video or Text?

I am sure this question might have appeared in other forums – but after writing innumerable blog posts, I am always curious as to what should be the apt medium of communication for creating blog posts. Should it be videos or should it be plain text to get the point across? I am not going to be using any marketing terminology πŸ™‚ …but rather a layman content writer’s viewpoint…

Let us see the pros and cons of each type.
