Why I don't want to work as a Data Scientist.

I studied Data Science and I don't want to work in that field.
Surprising... right?
Well... The Data Science reports are all screwed. The data collected has lot of things missing.
The universe is spontaneous. It can not be categorized in classes or clusters.
Companies prefer the most profitable analytics only. So, they ignore the minority.
What remains is a boring class or cluster of similar people.
And, minority is what increases diversity and leads to creativity and innovation.
And history of evolution tells us that whatever is a minority now may become a majority in the future and the current majority will just vanish.
So, the point is that, there are a lot of variables out there. You can remove some to get the results you want. But aren't they biased..?
Data science is all about bias. And biasing ruins everything. Remember the feeling when teachers helped their favourites leaving you and your other fellows isolated.
So, the government ignored a lot of consequences and just did everything back to back without letting the economy to take a breath. And what happens when you have to run and when you are about to stop, you have to suddenly run at a faster speed, YOU EXHAUST. And recovery takes some time.
Analogies look like they are irrelevant sometimes. My comparison of people, governments, softwares and nature seem illogical. But everything in the universe works in the same pattern.

The coherence of this is line to line. So, read as it is. Don't skip or it won't make sense.

However, individual statements are like a quote. So, Good luck.

Instruction Set Architecture

The (main) memory can be modeled as an array of millions of adjacent cells, each
capable of storing a binary digit (bit), having value of 1 or 0. These cells are organized in the form of groups of fixed number, say n, of cells that can be dealt with as an atomic entity. An entity consisting of 8 bits is called a byte. In many systems, the entity consisting of n bits that can be stored and retrieved in and out of the memory using one basic memory operation is called a word (the smallest addressable entity). Typical size of a word ranges from 16 to 64 bits. It is, however, customary to express the size of the memory in terms of bytes. For example, the size of a typical memory of a personal computer is 256 MB,
that is, 256*2^20 =  2^28 bytes.
In order to be able to move a word in and out of the memory, a distinct address has to be assigned to each word. This address will be used to determine the location in the memory in which a given word is to be stored. This is called a memory write operation. Similarly, the address will be used to determine the memory location from which a word is to be retrieved from the memory. This is called a memory read operation.
Three basic steps are needed in order for the CPU to perform a write operation
into a specified memory location:
1. The word to be stored into the memory location is first loaded by the CPU
into a specified register, called the memory data register (MDR).
2. The address of the location into which the word is to be stored is loaded by
the CPU into a specified register, called the memory address register (MAR).
3. A signal, called write, is issued by the CPU indicating that the word stored in
the MDR is to be stored in the memory location whose address in loaded in
the MAR.

ADDRESSING MODES

Information involved in any operation performed by the CPU needs to be addressed. In computer terminology, such information is called the operand. Therefore, any instruction issued by the processor must carry at least two types of information. These are the operation to be performed, encoded in what is called the op-code field, and the address information of the operand on which the operation is to be performed, encoded in what is called the address field. Instructions can be classified based on the number of operands as: three-address, two-address, one-and-half-address, one-address, and zero-address.
The different ways in which operands can be addressed are called the addressing modes. Addressing modes differ in the way the address information of operands is specified. The simplest addressing mode is to include the operand itself in the instruction, that is, no address information is needed. This is called immediate addressing. A more involved addressing mode is to compute the address of the operand by adding a constant value to the content of a register. This is called indexed addressing. Between these two addressing modes there exist a number of other addressing modes including absolute addressing, direct addressing, and indirect addressing.

Where to learn Ruby lang?

You can learn Ruby from Boris Pashkhaver's Ruby Course on Udemy. The course is suitable from absolute beginners to people who have learnt programming before. The instructor explains things clearly and gives good examples which are easy to understand.

Prerequisites : How to open a browser. Rest will be taught by the teacher. ;)

Psst : You will learn FizzBuzz and will never forget.

What won’t Silicon Valley admit about technology and progress?

That 87% of the Startups are unnecessary and don’t solve a real problem.

Silicon Valley produced some great companies and a legacy for ages.
Without Silicon Valley/Bay Area there probably would be no HP, Apple, Google, Uber, Dropbox etc. P.S.: (totally made those 87% up btw, that’s just what it feels like to me.)
