Bitcoins : Part 2

-

In the previous blog post we were looking at the problems with physical forms of money. So now according to our agenda lets talk about the solutions to those problems...

Solutions...

  • Plastic money like credit cards to make money portable.
    • But the above solution still go as the physical form of money.
  • Solution # 2 is that we make something that is digital. Where there is no need to have any middle man while doing transaction of money. no need for any central authority for check and balance. The system should be distributed as well as decentralized. (What this system is? Is it about bitcoins? Or Something else? )
    • But again many problems are associated with this system...
I am pausing this session here, now if you are really concerned about crypto-currency then what you need to do is: Go here (bitcoin.org/bitcoin.pdf), read this paper and write in the comment section what you found from this paper. Also think about some of the problems associated with Solution # 2.

(To be continued.....)

John went to the cafeteria 10 times at 1:00 P.M. on 10 Fridays, each time the cafeteria was closed at that particular time. John decided not to go to cafe at 1:00 P.M. on Friday because the cafe will be closed.  But wait! How did John know that the cafe will  also be closed on next Friday at 1:00 P.M.??? Yes, you are absolutely right.  "John Learned from his Experience that the Task of going to the cafeteria at 1:00 P.M. on Fridays resulted in waste of time, since the cafe was closed on each Friday, so it will Perform the same on the next Friday." In the above scenario, John learned something so we can call it " John Learning ". Similarly, if we replace John with some sort of Machine, that can learn from the Experience or from the History about how the tasks were performed in the past given certain situation. Such that the Machine will perform the same if the same task happen again in near future. Then this will be called as Machine Learning. To mak

   Data is a new oil. To channelize this data we need proper pipelines. These pipelines are mostly called ETL or data pipelines.  There are various tools out there to work out these Extract, Transform, and Load (ETL) operations.  Some of the scripting tools are:  - Python - SQL and NoSQL Apache provides a wide range of products that can be used as Data Engineering tools.  Some of the amazing apache DE services comprised of; - Hadoop - Spark - Kafka - Cassandra - Hive In addition, some cool DE tools are: - Tableau - Talend - MapReduce These DE tools provide a way to manage the data pipelines in a more effective, efficient, and better way.  Almost every Data-Oriented company in the corporate sector is highly dependent upon these technologies. They are leveraging many of the above-mentioned mechanisms for promising Data Services and Architecture. That's it for today. Hope you have enjoyed this article.

Yes, you have to take notes in the university class!  Before talking about the notetaking strategy, we will understand the importance of taking notes. Importance Of Taking Notes No doubt there are a few students who can produce good results without even taking notes in the class. But their number is least. Most of us need to make good notes in the class especially when we are in university. Notes are important because: They help us to keep track of what we have studied in the whole semester. Notes help us to prepare for the exams, in a very short time. We can refer to our notes for short quizzes in the eleventh hour. In addition to reading and listening, writing notes increases the ability to memorize the important concepts. It helps you to realize that you have done something in the class.

Before digging into E-commerce platforms, let's first understand what an E-commerce actually is? E-Commerce... According to the Tokenization Rule , E-commerce is the combination of "E" and "Commerce".  The word Commerce means trade or buying and selling of items, goods, services, hardwares and, softwares... etc. And " E " stands for "Electronic", electronic means something like electricity, like signals, like something in the form of electrons (at lower level).  Image Source So, the word " E-COMMERCE " means: " A type of trade, that is done using electronic devices (computer, mobile or ATM machines etc). "   And to achieve electronic commerce, what's the most important thing? think over it!  Yeah that's correct! your own Internet is the most important thing to do E-commerce.  Major areas of E-commerce are: On-line shopping or retailing On-line bidding or auction On-line soft

I am talking about Web applications . Web applications are the applications that run over the web or an Internet. There are some differences between website and web applications. Difference between Websites and Web applications.. The main differences between websites and web applications are as under: Websites: Provide information as a static file. Not very much interactive.

Data Analysis : Reading Habit Analysis

Reading in the 21st century? Are you serious !!! Dr. Suess, an American writer once said: The more that you read, the more things you will know. But how? How to read so much! Why read? How to get motivated to read? If you are in search of these answers, then you are on the right page! In the quest to find the answer to the question: “What motivates you to read?”, I asked different people to respond to this question. Initially, I thought to write a simple article based on different responses I got. then I wondered if I could critically analyze the responses. Hm… critically analyze! but, how? Well, in this era when even kids are using Machine Learning for predicting the amount of Eidi they would get from their grandpa, why couldn’t we use Machine Learning for analyzing reading habit of different people. So, to get started with our analysis, we need some material. Things we need Dataset Machine Learning algorithms Kaggle.com And I think we will run out of

Web Services : AWS (Amazon Web Services)

We have discussed the concept of cloud computing in the previous blog post.  If you want to host your website then you will buy a hosting and if you are not using cloud computing service then that web hosting service is a traditional web hosting service. But... If you are using cloud computing as you want; scalability, security, accessibility, availability and flexibility with less work done by yourself, then there comes AWS  (Amazon Web Services). AWS is the first (to my knowledge) cloud computing service provider. It is the daughter company of Amazon. Amazon.Inc was established almost 24 years ago by Mr. Jeffery Preston Bezos . And  about 12 years ago, Amazon.Inc launched a web service naming Amazon Web Services or AWS.  AWS provides a cloud server and you can do a lot of things using that cloud. Main services/products provided by AWS are:  Analytics Application Integration AR and VR (Augmented Reality and Virtual Reality) Cost Management Block Chain Business A

The website was for 24/7 and large amount of data needed to be managed and maintained . For this the management team of the company decided to launch their website onto the server. Initially the website got Launched successfully, but one day in the fine morning the CEO woke up from his/her slumber and got the Phone call from the manager.

CEO called an emergency meeting, in the meeting, the company decided to buy more servers as their data as well as the users were increasing .
