Reasons Why You Failed ….

You failed ,not because you don’t deserve it , or you are a loser , you failed because you didnt put up as much efforts as much you were supposed to , or maybe because your methods were wrong . You don’t need to feel upset just because everyone can make it in first shot , & you couldn’t , some are slow learners , some have different mindsets than the normal average people , it doesnt make you loser , it makes you different , & so you would have to take a different method than the rest.

It happened in my life too , something very easy that everyone could do , I couldn’t , I always wanted to drive two-wheeler , but whenever i asked people who already learned it , used to ask me if you don’t know how to ride bicycle , how can you expect to ride a two wheeler , that s the basic thing , but I didn’t believed it , it took time for me to learn to ride , but I kept on trying  , & now I can even drive it with a single hand , yeah I never thought of learning bicycle ,but than I never wanted to in the first place.

It made me realize that , sometimes the normal rules don’t apply to you , just because everyone could learn the two wheeler only after they learned bicycle doesn’t mean it is gonna be the same for you , you need to understand this , if you are failing at something again & again , than there are two reasons ,
-> You are not putting as much efforts & hard work as required.
-> Or you have to change the method , something is wrong & is not fitting.

Get inspired  by  others, but learn to recognize that their methods might not work for you too , make your own methods , ways to tackle things that are difficult to you , even if they seem very easy to others ,

Life is full of screwups. You’re supposed to fail sometimes. It’s a required part of the human existance.” 
― Sarah DessenAlong for the Ride

Einstein  was thrown out of school , we all know that story , but that doesn’t mean he was a loser , he just had a different mindset than others, the thing that he found difficult was a very simple task for all his other classmates ,there is always something special about you that you fail to recognize , look harder & you will know it eventually  ….
Just because you fail once, doesn’t mean you’re gonna fail at everything. Keep trying, hold on and always, always, always believe in yourself. Because if you don’t, then who will? So, keep your head high, keep your chin up and most importantly, keep smiling. Because life’s a beautiful thing and there’s so much to smile about!

You can start by changing your perception , you can boost up your confidence by reading , by doing something new , learning something new , you can keep those things with you that might have inspired you while making efforts for your goal , I always listen to those energy booster songs while doing something that is a bit difficult for me , I keep pictures of  my dear ones in my laptop , those happy memories brings me smile when I am stressed up , I read my favorite novel that always motivates me  The Alchemist , &  Paulo Coleho is my inspiration . You can also look for your role models , who will inspire you , & help you in a way you never  thought  of .

Thought Of the day :

There is only one thing that makes a dream impossible to achieve: the fear of failure.

Where did the People vanished ????

There are thousands of mysteries revolving in the infinite atlas of history , but two of ma most favorites are :
i> Croatoan – the lost colony
ii>Mary Celeste – A Cursed Ship with a Disappearing Crew
One link that connects both the mysteries is :” DISAPPEARING MASS” , the question arises how come so many people disappears in the thin air , even without leaving behind a single clue of their existence , why even after years of research & theories not a single valid reason is found about their disappearances. before moving further lets have a quick glance at this mysteries :

->                                                        CROATOAN ‘Lost Colony

Fans of the CW show Supernatural are familiar with the word “croatoan,” but for others, the word is unfamiliar, a throwback to history 101 and largely forgotten. Most people do not remember that the word, carved into a tree at Roanoke Island, North Carolina, is the single most important clue to an English settlement which mysteriously disappeared in 1590.

In the Supernatural episodes, “croatoan” was a virus, but in reality, no one really knows what the word means, although various historical scholars have their theories. Here is what we do know. About 117 English pioneers came to Roanoke Island to form a settlement. Three years later, the settlers were gone without a trace, leaving only the word “croatoan” carved into a tree. The story goes like this………

In 1585, English explorer Ralph Lane landed on the Outer Banks with a crew of 75 men, writing upon his arrival that they had come upon the “goodliest soyle under the cope of heaven.”

The enchantment didn’t last. The “First Colony” fought with natives, and food supplies quickly dwindled. They sent a party back to England seeking fresh supplies, but didn’t wait for their return. Instead, they hitched a ride back home with Sir Francis Drake, who was passing through after raiding Spanish ports in the Caribbean.

When the men with relief supplies arrived to find the colony abandoned, they left a detachment of about 15 and sailed themselves for England.

Undeterred by the chaos, Sir Walter Raleigh sent John White and a new group of settlers one year later to pick up the so-called “holding colony” and to found a new settlement in what is now Virginia. White was unable to find the men left behind, and Indians reported that other natives had attacked the group and forced them to flee by boat.

Concerned about their own future and plagued by a lack of food, the colonists persuaded White to return to England for help. He agreed, leaving behind 116 colonists and his newborn granddaughter Virginia Dare – the first English child born in the New World. The colonists promised White they would carve a Maltese cross into a tree if they encountered turmoil and were forced to flee.

White made it back to England, but was delayed for three years by war between Spain and England. When he returned in 1590, he found no trace of the colonists he left behind, aside from the post and the word “Croatoan.”

> Speculation abounds as to what happened to the settlers. One theory is that the group splintered into two factions, one faction was killed by hostile Indians, while another was assimilated into one of the friendly Indian tribes. No one really knows……….

*Moving onto our next mystery  ,One of the most famous ghost ships of all time is the Mary Celeste. This ship always seemed to have experienced bad luck, no matter where she went or who her passengers were.

->                                                        Mary Celeste”the cursed ship”

Even when the ship was known as the Amazon, after she was launched in 1860, she was involved in many accidents and went through a dozen different owners. No owner kept the ship for very long, since they always experienced bad luck with her. Around 1870, after the first ten years of misfortune, the ship was sent to New York, underwent extensive repairs, and was finally renamed Mary Celeste.

The captain of newly renamed Mary Celeste was Benjamin Briggs, who, along with his wife, daughter, and seven or eight crew members, departed New York on Nov. 7, 1872. They were bound for Genoa, Italy, and had a cargo of 1,700 barrels of alcohol. All seemed well upon departure, but the captain, crew, and passengers were never seen or heard from again. They literally disappeared off the face of the earth, and to this day, the mystery has never been completely solved.

Even though all persons aboard the ship disappeared, the ship itself did not. Nor did the cargo. However, just nine of the barrels were found opened once the shipment was finally inspected. On December 5, 1872, nearly a month after the Mary Celeste departed from New York, she was found on the sea, derelict, by the Dei Gratia ship.

The captain of the Dei Gratia was familiar with Captain Briggs and was surprised to find that he was missing. Briggs had a reputation of being a fair, honest man and an excellent captain. The Dei Gratia crew boarded the Mary Celeste to investigate. What they found was a mystery that no one ever found out the answers to. The ship wasn’t in the best condition, but it was still fine and seaworthy. It appeared as if the crew and passengers had left in a hurry.

The Galley wasn’t in the best shape, there was some water in between the decks, and the kitchen was a mess. There was also a rope hanging over the side and trailing in the water. It appeared that, despite that the Mary Celeste was still in decent condition, the crew had abandoned ship. But why? Why did they leave in such a hurry? How come they were never found again? Did their life boat sink? If they did make it to safety, why did they never contact anyone? Did they meet with foul play?

Most experts have agreed over the years that bad weather probably had nothing to do with the mystery. After all, the Dei Gratia didn’t experience any bad weather during its time in the area. Also, Captain Briggs was an excellent sailor. Why would he have his family and crew take the risk of leaving the ship when it was still in decent condition? He should have been to handle it, and he had probably experienced worse over the years.

Some suggest that perhaps pirates took over the ship, but why was nothing missing? Nine barrels were open, but none were missing. There probably wasn’t a mutiny against the captain, since the crew was mainly honorable soldiers who respected him. So, if no foul play was involved, and there was no sign of bad weather, why did the crew of the Mary Celeste leave the ship, and where did they end up? Were they eaten by sharks? Did a UFO have anything to do with their disappearance?

One theory that has been put forth, which is perhaps the most logical, is that the crew became worried over the raw alcohol, since alcohol fume was known to be volatile and even explosive. Briggs had never hauled alcohol before and didn’t know how to take care of it. Perhaps the nine barrels began leaking or somehow got torn open, filling up the hold with a possibly lethal mixture of fumes. Out of a sudden fear of an explosion, Briggs ordered everyone to hurry into the lifeboat, and in his haste forgot to secure the boat to the ship with the towline. This would explain why the rope was hanging down and drifting into the water, why nine barrels were opened, and why the crew seemed to have left in a hurry.

Of course, it still doesn’t account for the fact that there was water in between the decks, or what happened to the crew. In all probability, they all probably either drowned or died of thirst and exposure. Perhaps we’ll never know for sure what happened to the crew of the Mary Celeste, or why she seemed to bring bad luck with her everywhere she went.

Basic Concepts & History of Cryptography

* The oldest means of sending secret messages is to simply conceal them by one trick or another. The ancient Greek historian Herodotus wrote that when the Persian Emperor Xerxes moved to attack Greece in 480 BC, the Greeks were warned by an Greek named Demaratus who was living in exile in Persia. In those days, wooden tablets covered with wax were used for writing. Demaratus wrote a message on the wooden tablet itself and then covered it with wax, allowing the vital information to be smuggled out of the country.

 

The science of sending concealed messages is known as “steganography”, Greek for “concealed writing”. Steganography has a long history, leading to inventions such as invisible ink and “microdots”, or highly miniaturized microfilm images that could be hidden almost anywhere. Microdots are a common feature in old spy movies and TV shows. However, steganography is not very secure by itself. If someone finds the hidden message, all its secrets are revealed. That led to the idea of manipulating the message so that it could not be read even if it were intercepted, and the result was “cryptography”, Greek for “hidden writing”.

 

Cryptography takes two forms: “codes” and “ciphers”. The distinction between codes and ciphers is commonly misunderstood. A “code” is essentially a secret language invented to conceal the meaning of a message. The simplest form of a code is the “jargon code”, in which a particular arbitrary phrase, for an arbitrary example:

 

 The nightingale sings at dawn. 

— corresponds to a particular predefined message that may not, in fact shouldn’t have, anything to do with the jargon code phrase. The actual meaning of this might be:

   The supply drop will take place at 0100 hours tomorrow.

Jargon codes have been used for a long time, most significantly in World War II, when they were used to send commands over broadcast radio to resistance fighters. However, from a cryptographic point of view they’re not very interesting. A proper code would run something like this:

   BOXER SEVEN SEEK TIGER5 AT RED CORAL

This uses “codewords” to report that a friendly military force codenamed BOXER SEVEN is now hunting an enemy force codenamed TIGER5 at a location codenamed RED CORAL. This particular code is weak in that the “SEEK” and “AT” words provide information to a codebreaker on the structure of the message. In practice, traditional military codes are often defined using “codenumbers” instead of codewords, listed in a codebook that provides a dictionary of code numbers and their equivalent words. For example, this message might be coded as:

   85772 24799 10090 59980 12487

Codewords and codenumbers are referred to collectively as “codegroups”. The words they represent are referred to as “plaintext” or, more infrequently, “cleartext”, “plaincode”, “placode”, or “plaindata”.

Codes are unsurprisingly defined by “codebooks”, which are dictionaries of codegroups listed with their corresponding their plaintext. Codes originally had the codegroups in the same order as their plaintext. For example, in a code based on codenumbers, a word starting with “a” would have a low-value codenumber, while one starting with “z” would have a high-value codenumber. This meant that the same codebook could be used to “encode” a plaintext message into a coded message or “codetext“, and “decode” a codetext back into plaintext message.

 

However, such “one-part” codes had a certain predictability that made it easier for outsiders to figure out the pattern and “crack” or “break” the message, revealing its secrets. In order to make life more difficult for codebreakers, codemakers then designed codes where there was no predictable relationship between the order of the codegroups and the order of the matching plaintext. This meant that two codebooks were required, one to look up plaintext to find codegroups for encoding, the other to look up codegroups to find plaintext for decoding. This was in much the same way that a student of a foreign language, say French, needs an English-French and a French-English dictionary to translate back and forth between the two languages. Such “two-part” codes required more effort to implement and use, but they were harder to crack.

 

* In contrast to a code, a “cipher” conceals a plaintext message by replacing or scrambling its letters. This process is known as “enciphering” and results in a “ciphertext” message. Converting a ciphertext message back to a plaintext message is known as “deciphering”. Coded messages are often enciphered to improve their security, a process known as “superencipherment”.

 

There are two classes of ciphers. A “substitution cipher” changes the letters in a message to another set of letters, or “cipher alphabet”, while a “transposition cipher” shuffles the letters around. In some usages, the term “cipher” always means “substitution cipher”, while “transpositions” are not referred to as ciphers at all. In this document, the term “cipher” will mean both substitution ciphers and transposition ciphers. It is useful to refer to them together, since the two approaches are often combined in the same cipher scheme. However, transposition ciphers will be referred to in specific as “transpositions” for simplicity.

 

“Encryption” covers both encoding and enciphering, while “decryption” covers both decoding and deciphering. This also implies the term “cryptotext” to cover both codetext and ciphertext, though the term “encicode” is sometimes seen instead. The science of creating codes and ciphers is known, as mentioned, as “cryptography”, while the science of breaking them is known as “cryptanalysis”. Together, the two fields make up the science of “cryptology”.
