I still have not found any references to a "general theory of searching and finding". So I'm playing around with the concept of "search" and "search space". If you have any references for me I will be grateful. (But please *not* the Knuth book. I'm looking for a generalized, philosophical treatment, not computer algorithms.)
This is a one in a million chance. But our parallel visual processing makes this "needle in a haystack" easy to find.
If you want to see the pixel best - you have to choose the large format. But it's visible in the normal size too.

There is always the temptation to reject the random outcome - those numbers seem too close together - they do not feel really random. But this outcome is just as probable as any other outcome.
Secure Shell or SSH is a network protocol that allows data to be exchanged over a secure channel between two computers. Encryption provides confidentiality and integrity of data. SSH uses public-key cryptography to authenticate the remote computer and allow the remote computer to authenticate the user, if necessary.
SSH is typically used to log into a remote machine and execute commands, but it also supports tunneling, forwarding arbitrary TCP ports and X11 connections; it can transfer files using the associated SFTP or SCP protocols.
An SSH server, by default, listens on the standard TCP port 22.
An SSH client program is typically used for establishing connections to an SSHD daemon accepting remote connections. Both are commonly present on most modern operating systems, including Mac OS X, Linux, FreeBSD, Solaris and OpenVMS. Proprietary, freeware and open source versions of various levels of complexity and completeness exist.

A German Enigma machine, thought to be (by the Germans) unbreakable cryptography. Alan Turing and the code breakers at Bletchley Park didn't think so.
My bro made this.. really delicious (as he said! i didn't taste it!!)
I did a huge editing on this photo! .. the lower side of the cup from one photo and the upper side from another one! and i think the result is good enough, isn't?
I will have Cryptography exam, but i can't concentrate on exam so i decide to play with PS ..! hehe :D
Good Night!

The church "St. Martin und Maria", now used as the parish church of Sponheim, was part of an abbey, founded by Meginhard of Sponheim and his father. The abbey got consecrated in 1123, the first monks came from Mainz. After the Reformation the monks left the abbey. A try to reestablish monastic life here with the support of the Bursfelde Congregation ended unsuccessful. Another try ended in 1794, when the last monks fled the monastery from the approaching French troops.
Johannes Trithemius (aka "Johann Heidenberg") was abbot here between 1483 and 1505. He was not really liked by his monks, as he was preferred a very harsh monastic life. Johannes was very popular among the intellectual community in Germany as an lexicographer and historian.
As an early cryptographer, he was one of the greatgrandfathers of Alan Turing. In 1516, he published the "Polygraphiae", containing a "tabula recta", a cornerstone of modern cryptography.

I was in the RAF from Nov 1993 to Dec 2000. These pictures are from my trade training days at RAF Locking near Weston-Super-Mare, 9 Feb 1994 - 1 Aug 1994. I was on course TCO 114.
At RAF Locking I was trained as a Telecommunications Operator (TCO). A TCO mainly worked in Communication Centres or Signals Unit's, operating a variety of telegraphic, cryptographic, radio, and Morse equipment. TCO's were also trained as Telephonists where they worked in station telephone exchanges. TCO's could also serve in a field comms role at Tactical Communications Wing (TCW) RAF Brize Norton, a role in which I served in early 1998.
I later returned to RAF Locking in 1997 to undertake my Morse course (3 Mar 1997 - 10 Jun 1997); I was on QMC 41.
The operational units I served at were:
RAF Waddington
TCW, RAF Brize Norton (detached to Bahrain)
RAF Coningsby

The Postcard
A Hartmann postcard that was posted in Scarborough on Tuesday the 14th. February 1905 to:
Miss E.A. Smelt,
3, West Park Terrace,
Scarborough.
The brief message on the divided back of the card was as follows:
"Another for your
collection.
Hope you will like
it.
Love,
D.S."
Sir Beerbohm Tree
Sir Herbert Beerbohm Tree (17th. December 1852 – 2nd. July 1917) was an English actor and theatre manager.
Tree began performing in the 1870's. By 1887, he was managing the Haymarket Theatre, winning praise for adventurous programming and lavish productions, and starring in many of its productions.
In 1899, he helped fund the rebuilding, and became manager, of His Majesty's Theatre. There he continued to promote a mix of Shakespeare and classic plays with new works and adaptations of popular novels, giving them spectacular productions in this large venue, and often playing leading roles.
His wife, actress Helen Maud Holt, often played opposite him and assisted him with management of the theatres.
Although Tree was regarded as a versatile and skilled actor, particularly in character roles, by his later years, his technique was seen as mannered and old fashioned.
He founded the Royal Academy of Dramatic Art (RADA) in 1904, and was knighted for his contributions to theatre in 1909.
His famous family includes his siblings, explorer Julius Beerbohm, author Constance Beerbohm and half-brother caricaturist Max Beerbohm. His daughters were Viola, an actress, Felicity and Iris, a poet; and his illegitimate children included film director Carol Reed. A grandson was the actor Oliver Reed.
'Cats'
Beerbohm Tree features in one of the songs in the musical 'Cats': It is 'Gus, the Theatre Cat'. Here is part of it:
Gus is the cat at the theatre door
His name, as I ought to have told you before
Is really Asparagus, but that's such a fuss to pronounce
That we usually call him just Gus
His coat's very shabby, he's thin as a rake
And he suffers from palsy that makes his paw shake
For he was in his youth quite the smartest of cats
But no longer a terror to mice or to rats
For he isn't the cat that he was in his prime
Though his name was quite famous, he says, in his time
And whenever he joins his friends at their club
Which takes place at the back of the neighbouring pub
He loves to regale them, if someone else pays
With anecdotes drawn from his palmiest days
For he once was a star of the highest degree
He has acted with Irving, he's acted with Tree
And he likes to relate his success on the halls
Where the gallery once gave him seven cat calls
But his greatest creation as he loves to tell
Was Firefrorefiddle, the fiend of the fell.
Final Thoughts From Beerbohm Tree
"I was born old and get younger every
day. At present I am sixty years young."
"Ladies, just a little more virginity,
if you don't mind."
(Said to a motley collection of
women, assembled to play ladies in
waiting to a queen).
"Every man is a potential genius until
he does something."
"The only man who wasn't spoilt by
being lionized was Daniel."
"A man never knows what a fool he is
until he hears himself imitated by one."
"A charming fellow, and so clever:
he models himself on me."
"She kissed her way into society. I don't
like her. But don't misunderstand me: my
dislike is purely platonic."
"God is a sort of burglar. As a young man
you knock him down; as an old man you
try to conciliate him, because he may
knock you down."
"People are too apt to treat God as
if he were a minor royalty."
"Cynicism is the humour of hatred"
"The national sport of England is obstacle-racing.
People fill their rooms with useless and cumbersome
furniture, and spend the rest of their lives in trying to
dodge it."
"A committee should consist of three men,
two of whom are absent."
"It depends on each and
every one of me"
"When I pass my name in such large
letters I blush, but at the same time
instinctively raise my hat."
"Sirs, I have tested your machine.
It adds a new terror to life and
makes death a long-felt want."
{On being pressed by a gramophone
company for a written testimonial).
"My poor fellow, why not carry a watch?"
(Said to a man in the street who was
carrying a grandfather clock).
"A whipper-snapper of criticism who
quoted dead languages to hide his
ignorance of life."
"He is an old bore. Even the grave
yawns for him."
"Never say a humorous thing to a man
who does not possess humour: he will
always use it in evidence against you."
Frida Palmer
So what else happened on the day the card was posted?
Well, the 14th. February 1905 marked the birth in Blentarp of Frida Palmér. She was the first female Swedish astronomer with a doctorate.
Frida listed over 259 stars with irregular periodicity variability, examined their galactic distribution, arranged by spectral type.
She discovered that the light curves of some stars could be interpreted as interference between two or more simultaneous, periodic events in the stars.
Her academic career was stopped short because of World War II when she started to work at the Swedish National Defence Radio Establishment as a cryptographer. Palmer decoded Soviet marine signaling messages in the Arctic Ocean. Palmer never got any real recognition from her cryptography colleagues, who considered her an insignificant "star analyst".
Frida died on the 13th. October 1966.
The iphone is an amazing phone. I've had the 3G and I have been really happy about the build quality, the interface, the speed.
What I haven't been ok with is the way Apple locks out 3rd party app support. Not only obfuscating the database protocol, incorporating cryptographic signatures for non-DRMed mp3s but even going after websites publishing reverse engineered information on this.
And on top of that the stupid censorship of the app store, locking competing products away. Take care Apple, you make great products, but you're an ugly monopolist.

Art to puzzle over. This work, “An Stelle von” (Instead of) by the Austrian artist Hermann J. Painitz is a word puzzle. Painitz, one of more than 35 post-war Austrian artists whose works were selected for display in the Vienna International Centre when it opened in 1979, was interested in cryptography. The VIC is home to the UN headquarters in Vienna.

Edwards AFB 04/03/14
Boeing C-135C "Stratolifter" ("Specked Trout") (18345) (USAF 61-2269)(412th Flight Test Squadron Edwards AFB, Speckled Trout is the official name of a combined
SAF/CSAF support mission and concurrent test mission. It was also the official nickname given to the squadron and the C-135C, 61-2669 that was used by the Secretary and the Chief of Staff of the Air Force for executive transport requirements. Fully equipped with an array of communications equipment, data links and cryptographic sets, the aircraft served a secondary role as a testbed for proposed command and control systems and was also used to evaluate future transport aircraft The name Speckled Trout was chosen in honor of an early program monitor, Faye Trout, who assisted in numerous phases of the project. The word "speckled" was added because Trout apparently had "a lot of freckles."

A live demonstration of the rebuilt Colossus Mk II at Bletchley Park - a reconstruction of the world's first programmable digital electronic computer.
Colossus was designed to help staff at Bletchley Park decrypt messages sent between different parts of the German Army High Command. These had been encrypted using a Lorentz cipher machine - a device more complex than Enigma.
The Bletchley Park codebreakers were able to figure out the behaviour of the Lorentz machine two and a half years before they actually laid their hands on one, thanks to a horrendous mistake made by a German operator sending a message from Athens to Vienna on 30th August 1941. By the beginning of 1942, engineers at the Post Office Research Laboratories at Dollis Hill had produced a device called 'Tunny' that emulated the Lorentz machine's logic. Once cryptographers had worked out the Lorentz machine settings, these could be plugged into Tunny and the ciphertext could be fed in; if all was well, Tunny would produce the plaintext of the message as its output (in German, of course).
The problem was that working out the required Tunny settings by hand took weeks. A first semi-automated solution involved a machine nicknamed 'Heath Robinson' but this was later improved by Post Office electronics engineer Tommy Flowers, who designed and built the Mk I Colossus. This 1,500-valve machine was assembled in Bletchley Park F Block over Christmas 1943 and operated on its first message in January 1944, reducing the time to break the Lorentz cipher from weeks to hours.
