Block chain popularity secret

 Suppose you are transferring money to your family or friends from your bank account. You would log in to online banking and transfer the amount to the other person using their account number. When the transaction is done, your bank updates the transaction records. It seems simple enough, right? There is a potential issue which most of us neglect.

These types of transactions can be tampered with very quickly. People who are familiar with this truth are often wary of using these types of transactions, hence the evolution of third-party payment applications in recent years.  But this vulnerability is essentially why Blockchain technology was created.

Technologically, Blockchain is a digital ledger that is gaining a lot of attention and traction recently. But why has it become so popular? Well, let’s dig into it to fathom the whole concept.

Record keeping of data and transactions are a crucial part of the business. Often, this information is handled in house or passed through a third party like brokers, bankers, or lawyers increasing time, cost, or both on the business. Fortunately, Blockchain avoids this long process and facilitates the faster movement of the transaction, thereby saving both time and money.

Most people assume Blockchain and Bitcoin can be used interchangeably, but in reality, that’s not the case. Blockchain is the technology capable of supporting various applications related to multiple industries like finance, supply chain, manufacturing, etc., but Bitcoin is a currency that relies on Blockchain technology to be secure.

Blockchain is an emerging technology with many advantages in an increasingly digital world:

  • Highly Secure

    It uses a digital signature feature to conduct fraud-free transactions making it impossible to corrupt or change the data of an individual by the other users without a specific digital signature.
  • Decentralized System

    Conventionally, you need the approval of regulatory authorities like a government or bank for transactions; however, with Blockchain, transactions are done with the mutual consensus of users resulting in smoother, safer, and faster transactions.
  • Automation Capability

    It is programmable and can generate systematic actions, events, and payments automatically when the criteria of the trigger are met

Block chain technology

 over the past few years, you have consistently heard the term ‘blockchain technology,’ probably regarding cryptocurrencies, like Bitcoin. In fact, you may be asking yourself, “what is blockchain technology?” It seems like blockchain is a platitude but in a hypothetical sense, as there is no real meaning that the layman can understand easily. It is imperative to answer “what is blockchain technology, “including the technology that is used, how it works, and how it’s becoming vital in the digital world.

As blockchain continues to grow and become more user-friendly, the onus is on you to learn this evolving technology to prepare for the future. If you are new to blockchain, then this is the right platform to gain solid foundational knowledge. In this article, you learn how to answer the question, “what is blockchain technology?” You’ll also learn how blockchain works, why it’s important, and how you can use this field to advance your career.

What Is Blockchain Technology?

Blockchain technology is a structure that stores transactional records, also known as the block, of the public in several databases, known as the “chain,” in a network connected through peer-to-peer nodes. Typically, this storage is referred to as a ‘digital ledger.’

Every transaction in this ledger is authorized by the digital signature of the owner, which authenticates the transaction and safeguards it from tampering. Hence, the information the digital ledger contains is highly secure.

In simpler words, the digital ledger is like a Google spreadsheet shared among numerous computers in a network, in which, the transactional records are stored based on actual purchases. The fascinating angle is that anybody can see the data, but they can’t corrupt it

ISSB preparation tips

CSS versus ISSB : What do you want to do?

 If you want to join armed forces of Pakistan then you'll have to pass ISSB along with other tests. However if you want to serve as civil servant then go for CSS exams.

Comparing css officer with army officer, Well CSP officer right from the start have powers as CSP has to deal with public affairs mostly. So in public affairs matters CSP is powerfull. As for example ASP is more powerfull then Major of Army.

But after promotions of army officer to higher rank for example to Brig. OR Maj .Gen and so on. Powers of these ranked officers are aslo very much, as we all know we are enlslaved of our own army. Army is more powerfull then civil beurecracy.

But if you look in the perspective of direct powers then CSP has more powers than Army officals.

Army is indepennt organization while many CSP work under ministries. so politics can influence csp officer but not to an army offical.

Scholarship : how to get scholarships

 Dear Aspirants: I am sure you read Waqar bhai's post about Italian Scholarship Rejection and I have personally noticed that Pakistani Students are not represented in such a majority in US universities either. While I pursued my Undergraduate Degree in the US and now doing my Ph.D. there, I have noticed this dilemma, and tons of mentors have brought it to your attention as well.

T have other mentors that Scholarships are Competitive not because there are many students but also because you are competing against international talent too.

If you can not make the effort to open the link and read the requirements for the program then I can not comprehend how do you comprehend that you can sustain and do well abroad

If you are so uncertain about giving IELTS/TOEFL, constructing SOP, creating your CV, Giving the GRE, Making a Research Proposal; that we hope that someone just gives us all the information and we do not have to do much then we will continue to lack and be underrepresented


We need to think this fact that we must quit running after acceptance letters. I have seen students just mindlessly asking for an acceptance letter from professors that have research not even close to what they want to pursue.


Students continue to send the same email to every professor and then ask, WHY ARE WE REJECTED?


We do not take time to read the profile of the professor, read their research, read some of their papers and try to understand what are their active projects because we claim that "IT WASTES SO MUCH TIME".


If you think that doing hard work is waste of time than let me tell you that trying to find the shortcut is the biggest waste of your time because to achieve success NO SHORTCUT EXISTS


SO HOW TO RECTIFY THIS PROBLEM?


Try to spend some time reading the requirements of the program. Do not blindly apply as soon as you see the word "FULLY FUNDED"


Stop chasing acceptance letters and try to find a perfect match with you and the lab you want to do research in. 


Please start working on your profile by constructing a compelling CV, SOP and other material ahead of the application deadline. If you start gathering your documents days before your deadline than you will not be able to carefully make sure that you have fulfilled all the requirements


Do apply to multiple programs on the same SOP, IT IS NOT GOING TO WORK IN YOUR FAVOR

If you are applying to US, know that GRE is not some sort of a foreign BEAST! The test is designed for humans by humans and not for robots. We all take these exams and we all can do well, if we put the same dedication as we put in things that are of interest to us

If you can spend hours browsing the internet then you should also be able to spend hours trying to find scholarship opportunities

PLEASE understand the importance of RESEARCH! It is rather impossible to get into PhD if you have no research experience. Instead of sitting and blaming your country, your institutions, and other people, start taking responsibility of your actions!

If you did not have the opportunity to do research, you must do an internship or a job relevant to your field before you apply for PhD!

Do not assume someone knows that you know the skills. If you do not mention that in your CV, I can not know that you have Research Skills

MORAL OF THE STORY: Let us stop blaming others for our failure and take responsibility of our actions! Work hard! There is no success if you can not take the time to work hard! Failure should not disappoint you but let it teach you!he Biggest Problem is: TRYING TO FIND A SHORT CUT

Failure, turning failures to success


I wish someone told me this 10 years ago when I was just graduating with my bachelor. I wish there were seminars, books, and training courses on dealing with rejection. I wish there were special events where people shared their 'failure stories'.

Dealing with failure is such an important part of any person's life. If you think about it, the majority of our life is spent dealing with failures. We rarely get something on the first try.

What is failure? Failure is not when you half-heartedly applied for a job/scholarship and nobody replied. Failure is when you are at the end of your wits and you have no idea what to do next. Imagine being in an unfamiliar house, alone, and then suddenly power goes out, it is pitch dark, you have no idea where you are and you have no idea where to go. This is what real failure looks like.

Everyone sees failure, everyone witnesses such moments. If by any miracle you are have not seen such failures then there are two possibilities: Either you are incredibly lucky, which is nearly impossible. Or you are not aiming high enough, you are playing safe, in this case, you have failed by default already.

So now we know what is failure, then the biggest question here is how do we deal with it?

There are three possibilities when you suffer from failure:

You are not the right person for the position that you are aiming for.

You are the right person but you are not putting in the effort.

You are the right person, you are putting in your full effort but it is not in your naseeb*.

All the conventional advice on failure focuses on point no.2. The common advice says that you just need to keep going, just focus on your passion, just one more step. Edison failed 1000 times before he perfected the bulb, Dyson made 5126 prototypes before he finalized his bag-less vacuum design. We listen to these examples and curse ourselves, maybe we are not putting in the effort, maybe if we spent 12 hours instead of 8, that would make a difference. Maybe we should keep our head down and keep grinding...

Practice makes perfect, but wrong practice only gives wrong results.

You may be working on the wrong thing because you have the wrong idea of success in your head. It is possible that the idea of success was programmed in you from an early age by your environment and your society. Maybe what you are pursuing is not you, it's not suited for you or your personality. You are pursuing something for which you are a wrong fit.

Growing up in the 90s the idea of success for Pakistani children was becoming an Engineer or a doctor. An entire generation of Pakistani kids was programmed to believe that being a doctor or engineer was the best possible profession. (And it was for good reasons at the time). I was one of such kids, I believed that becoming an engineer or a doctor was the best possible way to be successful. So I did become an Engineer. It was during engineering when I found that I was not able to understand analytical concepts as easily as my other friends. But I still kept on going as much as I could.

It was during my first job as an engineer where I finally realized that I was not a natural at being an engineer. I saw my colleagues who were natural at it. They could talk about engineering problems, figure out solutions whereas I was trailing behind trying to catch up with them. The way they worked felt like a fish in the water. Effortless and enjoyable.

That's when I realized I want to be like a fish in the water. I want to choose what I am natural at.

Accepting your weakest areas is a blessing because when you do that you automatically start to find out what you are good at. Even if you don't know, your colleagues and peers start to see that and they ask for your help in those areas.

For me that area was communication. It was taking complicated ideas, thoughts, and queries and them putting them in words. I was a natural at it. It didn't seem anything special to me. To me it was effortless and therefore it seemed that anyone anywhere can do it. But that was not true. I would be asked several times by my managers and colleagues in drafting a particular tricky email or phone communication. Most of all, I enjoyed it. I enjoyed taking complicated ideas and putting them in words or explaining them to others.

The reason why I explained all this is that we are born with different talents and natural abilities. We have different IQs. It is useless to excel in a field where you are not natural and don't feel you are enjoying it.

So to summarise, this is what you should be feeling internally when you are doing something that aligns with you:

You do not feel it's a special talent because it comes naturally to you. However, when others see you working they tell you that it is not normal. It doesn't seem like work to you. It just flows through you like water.

You enjoy the process, no matter what the outcome you really enjoy doing it. A true blood entrepreneur gets a thrill every time there is a new business idea in his mind, he gets a kick every time there is a roadblock. The hustle, and the grind motivates him. A natural Engineer enjoys the problem, formulating complex equations. Analytical thinking does not bore him.

How do we find what we are natural at? We continuously explore, take risks, and then take feedback. We push our limits and risk failure.

So failure is an essential part of failing less. But we learn from that experience. Did we enjoy it? did it feel right to us?

When we find what we are a natural at then the reason no. 2 is eliminated. Because whatever we do it feels like play to us. We are not afraid of working. In fact, it does not even feel like work to us. We can spend hours, days just happily working on that thing.

This brings us to reason no.3 for failure: Maybe we are a natural at something, maybe we are even working as hard as we can, but we are still not getting it. Why does it happen? Maybe it is not in our naseeb. It is not destined for us.

It took me a very long time to understand this, but let me explain with an example.

When I was 15 I started memorizing the Quran. It took me 3 years of continuous studying and I was able to accomplish that. During my time I saw several students, who were diligent, intelligent and hardworking. Their parents came with the most sincere and deep-seated desire so their child can become a Hafiz-e-Quran, they would hire the best teachers, create the most positive environment for their kid. The kid himself would work hard. Studying day and night. But it wouldn't work. They wouldn't be able to do it. Everything on paper would say otherwise. But still, they couldn't. And no matter how much they tried to force it, it wouldn't work. They would fail again and again.

To this day I do not think it was a lack of intention, or hard work. God didn't love them any less than He loved me. It just wasn't destined for them.

It simply wasn't meant to be.

That realization is the hardest to stomach. Because there are no apparent reasons for our failure. We always want to know reasons, but there are places where logic cannot go, and that's where faith comes in. Faith and belief that we did our best, but it wasn't meant to be.

Failure is essential part of life, but it extremely important to fail at the right thing. Learning from the failure and then calibrating our actions.

I hope you learned something important from this guide. Please comment and let me know what you think.

Difference between socialism and capitalism

 Capitalism and socialism are generally seen as polar opposites, and discussions of either system are often framed as in opposition to the other. The modern idea of socialism has roots in Greek philosopher Plato but emerged as a popular political idea in the early 19th century among German radicals like Karl Marx and Friedrich Engels. There are many forms of socialism, but at its core, socialism is an economic system in which a whole community — not just bosses or private companies — control the means of production equally. It assumes that people are naturally cooperative, instead of competitive. The goal of socialism is an egalitarian society run by democratically elected representatives for the benefit of all in accordance with a set of collectively determined parameters; unlike under capitalism, industry and production is run by the state, and the acquisition of private property is seen as counterproductive. Capitalist critics of socialism believe that the system slows economic growth, rewards worker laziness, and can stifle individual rights and free expression.

In a capitalist country, the focus is on profits over anything else; in a socialist country, the public is seen to be more important, and social welfare is a major priority. The United States, the U.K., and Germany are examples of modern capitalist countries. Many other countries like Norway, Sweden, Canada, and the Netherlands incorporate socialist ideas into their societies, as does the U.S. to some degree; for example, universal health care and Social Security are both socialistic concepts
