+
+## Data encoding
+
+**TL;DR:** Encoding involves the use of a code to change original data into a form that can be used by an external process [^1].
+
+Encoding is the process of converting data into a format required for a number of information processing needs, including:
+
+- Program compiling and execution
+- Data transmission, storage and compression/decompression
+- Application data processing, such as file conversion
+
+Encoding can have two meanings[^1]:
+
+- In computer technology, encoding is the process of applying a specific code, such as letters, symbols and numbers, to data for conversion into an equivalent cipher.
+- In electronics, encoding refers to analog to digital conversion.
+
+## Glossary
+
+**deoxyribose**
+:  A five-carbon sugar molecule with a hydrogen atom rather than a hydroxyl group in the 2′ position; the sugar component of DNA nucleotides.
+
+**double helix**
+:  The molecular shape of DNA in which two strands of nucleotides wind around each other in a spiral shape.
+
+**nitrogenous base**
+:  A nitrogen-containing molecule that acts as a base; often referring to one of the purine or pyrimidine components of nucleic acids.
+
+**phosphate group**
+:  A molecular group consisting of a central phosphorus atom bound to four oxygen atoms.
+
+## Bit of theory and history
+
+History and explanation of what DNA is and where is used.
+
+### Quick history of DNA
+
+- **1869** - Friedrich Miescher identifies "nuclein".
+- **1900s** - The Eugenics Movement.
+- **1900** – Mendel's theories are rediscovered by researchers.
+- **1902** - Sir Archibald Edward Garrod is the first to associate Mendel's theories with a human disease.
+- **1944** - Oswald Avery identifies DNA as the 'transforming principle'.
+- **1950** - Erwin Chargaff discovers that DNA composition is species specific.
+- **1952** - Rosalind Franklin photographs crystallized DNA fibres.
+- **1953** - James Watson and Francis Crick discover the double helix structure of DNA.
+- **1953** - George Gamow and the “RNA Tie Club”.
+- **1959** - An additional copy of chromosome 21 linked to Down's syndrome.
+- **1965** - Marshall Nirenberg is the first person to sequence the bases in each codon.
+- **1977** - Frederick Sanger develops rapid DNA sequencing techniques.
+- **1983** - Huntington's disease is the first mapped genetic disease.
+- **1990** - The first gene found to be associated with increased susceptibility to familial breast and ovarian cancer is identified.
+- **1990** - The Human Genome Project begins.
+- **1995** - Haemophilus Influenzae is the first bacterium genome sequenced.
+- **1996** - Dolly the sheep is cloned.
+- **1996** - 'Bermuda Principles' established.
+- **1999** - First human chromosome is decoded.
+- **2000** – Genetic code of the fruit fly is decoded.
+- **2002** – Mouse is the first mammal to have its genome decoded.
+- **2003** – The Human Genome Project is completed.
+- **2013** – DNA Worldwide and Eurofins Forensic discover identical twins have differences in their genetic makeup [^2].

+### What is DNA?
+
+Deoxyribonucleic acid, a self-replicating material which is **present in nearly all living organisms** as the main constituent of chromosomes. It is the **carrier of genetic information**.
+
+> The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff.
+>
+> **-- Carl Sagan, Cosmos**
+
+The nucleotide in DNA consists of a sugar (deoxyribose), one of four bases (cytosine (C), thymine (T), adenine (A), guanine (G)), and a phosphate. Cytosine and thymine are pyrimidine bases, while adenine and guanine are purine bases. The sugar and the base together are called a nucleoside.

+
+## Encode binary data into DNA sequence
+
+Todo ...
+
+As an input file you can use any file you want:
+- ASCII files,
+- Compiled programs,
+- Multimedia files (MP3, MP4, MVK, etc),
+- Images,
+- Database files,
+- etc.
+
+Note: If you would copy all the bytes from RAM to file or pipe data to file you could encode also this data as long as you provide file pointer to the encoder.
+
+### Basic Encoding
+
+As already mentioned, the Basic Encoding is based on a simple mapping. Since DNA is composed of 4 nucleotides (Adenine, Cytosine, Guanine, Thymine; usually referred using the first letter). Using this technique we can encode log<sub>2</sub>(4) = log<sub>2</sub>(2<sup>2</sup>) = 2 bits using a single nucleotide. In this way, we are able to use the 4 bases that compose the DNA strand to encode each byte of data. [^4]
+
+| Two bits | Nucleotides      |
+| -------- | ---------------- |
+| 00       | **A** (Adenine)  |
+| 10       | **G** (Guanine)  |
+| 01       | **C** (Cytosine) |
+| 11       | **T** (Thymine)  |
+
+With this in mind we can simply encode any data by using two-bit to Nucleotides conversion

 No matter how hard we try to reinvent processes in software development we still haven’t found perfect solution for this. And to dismiss SDLC just because it’s something old is as ridiculous as the concept of designers being user experience gurus. As I have written couple of times before designers have their place and is not in the UX community. Most of them probably never heard of Jakob Nielsen and this proves a lot. Don’t get me wrong. There are designers out there that are absolutely amazing in what they do, but most of them are not. Good design has little to do with how things look in my opinion. But it has very much to do with how product behaves. And to take a chance on design look only is scary to me.

 Many posts have been written regarding profiling in Golang and I haven’t found proper tutorial regarding this. Almost all of them are missing some part of important information and it gets pretty frustrating when you have a deadline and are not finding simple distilled solution.

 I get asked a lot what the hell I actually do. I find it funny but I guess it is my fault in most cases. I try not to be the kind of a man that is always talking about his work. I live in a small village and most of my neighbours probably have no idea what I actually do. And I am ok with that.  I prefer this. But on some occasions I find it disturbing how people judge other people just because they don't understand what they are all about. Many of them probably think I am some strange kind of a looser that is awake all the time and works from home. He probably plays games and type on a computer :) What kind of a job is that? That is no job at all! :) You work for eight hours, then you go home and drink a beer and go work in your workshop. This is what real men do!
