Valgo-Jorge Luis Borges.-

Hoy quiero compartir con ustedes este texto que según creo, pertenece a J. L.Borges.


De tanto perder aprendí a ganar, de tanto llorar se me dibujó la sonrisa que tengo. Conozco tanto el piso que solo miro en Cielo. Toqué tantas veces fondo que, cada vez que bajo, ya sé que mañana subiré. Me asombro tanto cómo es el ser humano, que aprendí a ser yo mismo.

Tuve que sentir la soledad para aprender a estar conmigo mismo y saber que soy buena compañía. Intenté ayudar tantas veces a los demás que aprendí a que me pidieran ayuda.


Traté siempre que todo fuera perfecto y comprendí que todo es tan imperfecto como debe ser(incluyéndome).


Hago sólo lo que debo, de la mejor forma que puedo y los demás que hagan lo que quieran.


Vi tantos perros correr sin sentido, que aprendí a ser tortuga y apreciar el recorrido .Aprendí que en esta vida nada es seguro, solo la muerte...


Aprendí que nadie me pertenece, y aprendí que estarán conmigo en tiempo que quieran y deban estar, y que quien realmente está interesado en mí me lo hará saber a cada momento y contra lo que sea.


Que la verdadera amistad Sí existe pero no es fácil encontrarla.


Que quién te ama te lo demostrará siempre sin necesidad de que se lo pidas. Que ser fiel no es una obligación sino un verdadero placer cuándo el amor es el dueño de ti. Eso es vivir...


La vida es bella con su ir y venir, con sus sabores y sinsabores...aprendí de los errores pero no vivo pensando en ellos, pues siempre suelen ser un recuerdo amargo que te impide seguir adelante, pues hay errores irremediables.

Las heridas fuertes nunca se borran de tu corazón pero siempre hay alguien realmente dispuesto a sanarlas. Y no te esfuerces demasiado que  las mejores cosas de la vida suceden cuando menos te las esperas.


No las busques, ellas te buscan. Lo mejor está por venir.

La Fortaleza digital-Dan Brown.-

Comenzaremos haciendo alusión a la nota del autor, quién textualmente afirma...


"Para Fortaleza Digital, mi primer novela, elegí como escenario mi ciudad europea preferida...la adorable Sevilla. Viví en ella un año entero, durante mi época de estudiante de la Universidad de Sevilla(...)Durante aquél año, me enamoré de la ciudad y sobre todo de su gente(...)He llevado a mis padres y a mi familia a conocer Sevilla y hasta he aprendido a bailar sevillanas. De igual modo que mi ciudad natal está en Estados Unidos, Sevilla tiene aspectos maravillosos y otros que no lo son tanto(...)"



Fortaleza Digital fue la primer novela de Dan Brown. Nació en Nueva Inglaterra-EEUU-.Es hijo de un matemático y una intérprete de música sacra y desde muy pequeño, ha sentido un natural interés por los códigos y las claves secretas.



Ya en el Cap.1 de la novela, nos encontramos con Susan Flecher, a quién el timbre del teléfono la arranca completamente de su sueño...era David Becker.


Pero a Susan la esperaba una nueva misión en Criptografía. Y quién era David Becker? Nada más ni nada menos que el profesor más joven de la Universidad de Georgetown, brillante especialista en idiomas extranjeros.Era el hombre a quién Susan amaba...era guapo e inteligente...



La división de Criptografía era un grupo de élite de matemáticos. El trabajo de los criptógrafos consistía en estudiar el código y extraer de él el mensaje original. LLamaron a Becker para traducir unos códigos.


Cuándo lograron decifrar el código, Becker no tenía ni idea que oscuros secretos había revelado, pero la NSA se tomaba muy en serio el deciframiento de códigos.


Todos quiénes estaban relacionados con la criptografía conocían la existencia de la NSA...era algo así como el hogar de las mejores mentes criptográficas del planeta. La NSA tenía como uno de sus objetivos proteger la comunicación del gobierno de Estados Unidos e interceptar las comunicaciones de potencias extranjeras.



Becker de pronto, es llevado ante Susan...eran dos mentes analíticas, inmunes en teoría a encaprichamientos irracionales, pero de alguna manera, mientras hablaban de morfología lingüística, se sentían como una pareja de adolescentes enamorados.




Tanto el FBI como la CIA y los consejeros en materia de política exterior de Estados Unidos, dependían del espionaje de la NSA para tomar decisiones.






En cierta ocasión, Susan le comenta a David que Julio César fue el primer escritor de códigos secretos de la historia.



La cima de la encriptación no informática se alcanzó durante la Segunda Guerra Mundial...fueron los nazis quiénes construyeron una asombrosa máquina de encriptación llamada Enigma.



Durante la década de 1980,La NSAfue testigo de una revolución en las telecomunicaciones que cambió el mundo del espionaje para siempre...el acceso público a Internet...la llegada del correo electrónico, más precisamente.





Los usuarios de informática del mundo, descubrieron que el gobierno de EEUU tenía libre acceso a sus comunicaciones por correo electrónico y esto lo enojó muchísimo.



Tanto programadores como emprendedores empezaron a buscar una forma para conseguir que el correo electrónico fuera más seguro.




Llegó la hora en que eso ocurrió y los usuarios podían enviar correos electrónicos con toda confianza.



Strathmore era el jefe de Susan...un hombre corpulento, de extremidades largas, ojos grises que reflejaban confianza...




El trabajo de Susan hasta ahora, había consistido en hacer rendir al máximo al ordenador más secreto del mundo....Transltr.Ahora el ordenador llevaba más de quince horas intentando descifrar un código.Existía realmente un código indescifrable?





Parecería que ese código era producto de un nuevo algoritmo de encriptación.




Tanto matemáticos como programadores creaban nuevos algoritmos cada día...había cientos de ellos!!


Para Transltr todos los códigos eran iguales, con independencia del algoritmo empleado para encriptarlos...


El sistema era más o menos así...el algoritmo genera una clave de acceso que considera segura y el ordenador continúa probando hasta que la descubre.




Susan estaba perpleja....estaba convencida de que existía otra explicación....una falla técnica...un virus....cualquier cosa era más probable que un código indescifrable....



Por otra parte, el creador de Transltr era Ensei Tankado y ahora su creación parecía obsoleta...


Tankado aún no había nacido durante la Segunda Guerra Mundial, pero estudió todo sobre ella.


Nunca podría aceptar que la bomba le hubiese impedido conocer a su madre, quién había fallecido al dar a luz.




En 1945, antes que Ensei naciera, su madre y sus amigas, viajaron a Hiroshima para trabajar como voluntarias en los centros de quemados.



Más adelante, el ordenador le abriría mundos inexplorados a Ensei Tankado, quién sería reconocido como un genio.



Cuándo Ensei fue mayor, dio clases, ganó dinero y consiguió una beca en la Universidad de Doshisha.Leyó acerca de Pearl Harbor y los crímenes de guerra japoneses.



Es así como su odio por los norteamericanos se fue aplacando poco a poco...se convirtió en un budista devoto.




A la edad de 20 años, Ensei Tankado era una figura de culto clandestino entre los programadores...IBM le ofeció un visado con un permiso de trabajo y un puesto en Texas.





Tres años después, había abandonado IBM, vivía en New York y desarrollaba software por cuenta propia.




Y como mucho de los creadores importantes de algoritmos de encriptación, Tankado fue cortejado por la NSA...y decidió acudir a la entrevista....




TRabajó en el Departamento de Criptografía de la NSA, del cuál se alejaría más adelante...



Ensei Tankado, más tarde, crea una fórmula matemática capaz de generar códigos indescifrables...se llamaba fortaleza digital y estaba disponible en Internet....pero lamentablemente, Tankado sería encontrado muerto en Sevilla, España ...Es Becker quién intentará resolver el asesinato de Tankado...





La tecnología avanza exponencialmente, eso hay que reconocerlo...



Los algoritmos de encriptación podrían perder su seguridad y por lo tanto, se necesitarán más algoritmos para ir un paso hacia adelante de los ordenadores del futuro...



Cabe aclarar que Susan había creado un programa rastreador que se camuflaba en un correo electrónico y podía enviarlo a la dirección falsa del usuario y la empresa la enviaba a la dirección auténtica.





Hasta aquí, estimado lector, te presenté a los protagonistas de esta maravillosa novela e intenté describir un poco el argumento de la misma...





Espero haber sido clara y te invito a que sigas leyendo esta obra, con el fin de introducirte en el mundo de los códigos, ordenadores y programadores...



Creo que es una muy buena obra de Dan Brown, nos introduce en un mundo muy particular donde no faltan componentes como espías o crímenes no resueltos...Otra gran obra de este autor que merece ser leída...

The Great Seal-2-

Where Miles Hendon is concerned, he got of the pitched battle that had separated him from Edward, penilesses. He had been stolen all he got left.A few hours later, he was found prowling within the palace. He was asking about a beggar boy who said he was the King.

   



They took him at Edward'spresence. When he was before the boy. in the Royal hall, surrounded by the court, he exclaimed...






-well, The King of Dreams and Shadows on his throne!




Suddenly, he gathered a chair, planted it in front of the King and sat down on it. The guards ran to stop him but the King cried out...







-leave him, he ordered. I gave granted this right to him and his descendents, Remember it, he is my well-beloved savior, Miles Hendon. I orderer him knight because he saved my life in many opportunities.






Miles dropped upon his feet. Seconds after that, when he rose, he saw among the nobles the twisted face of Hugh Hendon, his heartless younger brother. When Edward discovererd it, he ordered to seize him and the Hendon's estates to be returned to Miles.



After, Tom Canty entered the hall, dressed with elegant robes and preceded by an usher.



-I am well pleased with you, Tom Canty, the King said.







-I have been told you have governed the realm with wisdom and justice. Your mother and sisters will be cared for and if you wish your father shall be hanged.And you, you will be from this day o, duirng life , governor of the shelter of the Poor.As long as my reign lasts, anybody going there will have food and a shelter.And Know you all that this Young boy has been King!He will be distinguished by the blue dress that now wears and will have the Little of king'sward.








EdwardVI lived not many years. During his reign, Miles Hendon and Tom Canty were his favorites and they both mourned bittterly his early death.




They sat there was not another reign more merciful tan that of the child King Edward, and maybe one has to reflect about the possibility that it was due to the extraordinary adventures that Edward lived, thanks to a nature fancy...That a prince and a beggar shared the same face.

the Great Seal.-

-These proofs are not satisfactory, said the Lord Protector.





-Let'see , I know...Tell me where the Great Seal is !







On so trivial a thing depends a throne and a dynasty!





For only he that is the true King can so answer.




And then in a sovereign gesture that left all the crowd of dignataries and nobles astonished, the ragged boy sent a lord to search the seal in a small box hidden in his cabinet.





And explained his location with all details. The Lord left towards the palace and the crowd remaind in silent.






But the Messenger came back empty-handed. Again the sympathy tides of the crowd left Tom ran aground in the throne and cast the other into the sea. When suddenly Tom cried...





-The seal you are talking about, is it a square object, thick and with  big handle?I know where it is !And also his  Highness does!It was the last object you took before rushing from palace!Where did you keep this seal! Try to remember.








After a lot of efforts, Edward remembered. He had kept the seal in an arm of an armor hanged on the Wall.And he had done it before leaving, dressed in Tom'srags, to scold the guard.









Again, a Lord went to the palace and this time, he did return with the Great Seal. Tears welled up from the eyes of dignataries and many other important vassals.Edward prevented anybody laying a hand upon Tom. And addressing him, he asked....




-How was it that you knew the Seal was, when I could not remember it myself?



-I used it several times, Tom answered-




-What did you use it for ?Edward asked.



-To crack nuts with, Tom said.



An avalanche of Laughter greeted the answer.If a doubt remained in the presents, this scene had dispose of it. The royal robe of state flied from the beggars's shoulders to Edward's hiding the ragged robes.




And when the Crown was set upon the head of the genuine King, the bell towards seemed to explode with happiness and the cannons thundered, making the London foundations tremble.

The recovered throne.-

When they reached the Abbey, the Deep booming of artillery sounded as salute. Tom dismounted from his horse and went up the stairs with a somber seriosness. He walked through the nave, full of nobility and adorned with indescribable luxury.







He walked started with a triumphant music. All the steps of protocol were followed and the moment of the coronation drew nearer. And the Crown was at centimetres of the boy'head, when in the great central aisle, as coming from nowhere, appeared the small figure of a boy dressed with rags and foul smelling.







-I forbid you to set the crowd upon that head!I am the King! he shouted.






The soldiers seized him at once, but Tomy Canty, in his regal vestiments, jumped from his seat and step forward.








-loose him immediately!He is the King!he ordered.







The Lord Protector said...



-His ancient malady is upon him again!Take the intruder to the Tower!







But Tom went on addressing the soldiers.







-Release him or you are dead! he said-I The King, order it!






The guards then, set Edward  free and Tom fell on his Kness before him and said...



-My Lord let me be the first to offer you my life and swear fidelity to you. Put on your Crown and recover what is yours.






And when Tom raised again, a murmur of admiration went through the abbey. Except for the clothes, the two boys were identical.







But the Lord Protector was not convinced at all and begged permission, to the ragged boy, to ask him a few questions that only the true King could answer.






Edward accepted and answered in a absolute precisión many questions about his deceased father, about the princesses and about the location of the furniture in every room in the palace. But the Lord Protector was no satisfied. The tide for and against the ragged boy turned direction among the crowd at every minute, one momento in favor and in the next against.

The coronation.-

In the meantime, in palace Tom was being prepared for the ceremony. His memories about the true King, with whom he had exchanged his beggar clothes for those of a prince, had faded away. He now behaved as if destinity had made posible for him to reach the England throne,

 





Also the memories of his mother and sisters, who so long he wanted to see on the first days, had followed the same road out if his mind, giving way to enjoying the palace pleasures. And everybody at the court , when they observed Tom, thought his madness belonged to the past.







Dressed, scented and adorned with invaluable jewels, Tom was helped to mount his horse. He had to cross the city and go to W Abbey, He left escorted by hundreds of guards. The former beggar was delighted seeing that, when he appeared, everybody gave him affected bows.Waving one way and another, from time to time he scattered a handful off Golden coins to the delirious multitude.


Suddenly, among the thousands of persons that were fighting to get closer to him, he caught sight of the pale and astounded face of his mother,









Tom, consternated, covered his face with his hands, with its palms outwards.It was an unmistakable gesture of his. The mother, then to reach the boys horse. She embraced Tom'leeg and covering it with kisses, exclaimed...





-Ah, mi child, my Darling.



The same instant an officer of the King'sguard snatched the woman away and sent her reeling back to the crowd.




-I do not know you, woman...said Tom.







But when he turned back and saw his mother being pushed away by the guard, with such and infinite sad face, the splendor of the parade and the sweetens of the day withered for him and he was again Tom Canty, born a beggar.



Ashamed, his heart filled with dark clouds, he neither saw nor Heard the crowd. He stopped saluting them with his radiant gesture.









The lord Protector approached and encouraged him to shake off the fatal humor, as if he did not the people'sjoy would also fade.








Tom tried to smile and scattered a few more coins, but it was useless. That seemed sad and forced. The Lord Protector told him.











-It has been that beggar the one who provoked the sadness of your highness.








-She is my mother-Tom answered.




-Oh my god!He is gone mad again....the Lord Protector groaned.

Good Hendon story.-

When Miles and the Little King reached by horse the nearby village To Hendon's family house, the soldier was as excited as in holiday day. But in the old family house there was only a man.
 



It was Hugh, the wicked younger brother, who denied completely knowing Miles. He said his brother had died in a battle, as a letter, all the ones in the house had read, affirmed. The old father and Arthur, the eldest brother, had also died. So, Hugh was the landorf of all that land. His wife was Edith, Miles Young love.




The servants and the same Edith said they knew him not. Miles, then, infuriated and his stea hand closed on Hugh'neck.





Damned fox-hearted! he said. I see the trap. You yourself forged the letter that informed of my supposed death. And you have stolen my bride and my domains.




Hugh managed to relieve himself of such a grip and hurried to the village in search of the guards. Edith approached Miles then, begging him to the hence. But the soldier was ready to face whatever it took. He cold not do much against the guards eho led to prison not only Miles, but also the King of England. Miles was put in a snare and he discovered, in his own flesh,what it meant to be someone and nobody recognizing you.





Finally they were released under the ocndition of coming back no more to those lands. Miles rode off with the Little King completely humiliated and sad. Edward encoureged his friend to gallop hastily. He wanted to rwach London before the ceremony of the coronation of the false King took place. Miles, in the meantime, had decided to beg for justice to the new monarch and started stirring his horse more cheefully.





When they stepped into the city the found it full of peoplewho had arrived there to see, even from a distance, the coronation




The eyes of the people were gleaming, hlped by beer.




A free fright among two groups of howling people, separated Miles and Edward from each other.
