A plugboard, or control panel (the term used depended on the application area), is an array of jacks, or hubs, into which patch cords can be inserted to complete an electrical circuit. Control panels were used to direct the operation of some unit record equipment. Plugboards were used on some cipher machines, and some early computers.
Control panels were introduced in 1906 for a Hollerith tabulator, earlier machines had been hard wired for specific applications. Removable control panels were introduced with the Hollerith (IBM) type 3-S tabulator in the 1920s. Applications then could be wired on separate control panels, and inserted into tabulators as needed. Tabulator functions were implemented with both mechanical and electrical components. Control panels simplified the changing of electrical connections for different applications, but changing most tabulator's use still required mechanical changes. The IBM 407 was the first IBM tabulator that did not require such mechanical changes; all the 407's functions were electrically controlled and were completely specified by the application's control panel and carriage tape. Removable control panels came to be used in all unit record machines where the machines use for different applications required rewiring. For most machines with control panels, from collators, interpreters, to the IBM 407, IBM manuals describe the control panel as "directing" or "automatic operation was obtained by...". The control panels of calculators, such as the IBM 602 and IBM 604, that specified a sequence of operations, were described as being a program.
Marian Adam Rejewski [ˈmarjan reˈjefski] ( listen) (16 August 1905 – 13 February 1980) was a Polish mathematician and cryptologist who in 1932 solved the plugboard-equipped Enigma machine, the main cipher device used by Germany. The success of Rejewski and his colleagues Jerzy Różycki and Henryk Zygalski jump-started British reading of Enigma in World War II; the intelligence so gained, code-named "Ultra", contributed, perhaps decisively, to the defeat of Nazi Germany.(Note 1)
While studying mathematics at Poznań University, Rejewski had attended a secret cryptology course conducted by the Polish General Staff's Biuro Szyfrów (Cipher Bureau), which he joined full-time in 1932. The Bureau had achieved little success reading Enigma and in late 1932 set Rejewski to work on the problem. After only a few weeks, he deduced the secret internal wiring of the Enigma. Rejewski and his two mathematician colleagues then developed an assortment of techniques for the regular decryption of Enigma messages. Rejewski's contributions included devising the cryptologic "card catalog," derived using his "cyclometer," and the "cryptologic bomb."
Estoy sentado frente a mi balcón
Veo la lluvia caer
Recordando el brillo de tu piel
Cuando fui tu amor
Veo tu foto al amanecer
Y una lágrima brotó
Recordando la suavidad de tu piel
Cuando me diste tu amor
-coro-
Y enloquezco sin ti
Voy muriendo sin tu amor
Voy muriendo extrañando tu piel
Y enloquezco extrañándote
Voy muriendo extrañándote
Escuchando esa vieja canción
Que se oía en la radio
Recordé cómo solíamos reír
Cómo solíamos jugar
Por las noches al tomar el café
Solitario sin nada que hacer
Veo el poema que escribiste por mí
Pero no estás junto a mí
Esa noche enloquecí
(Coro)
Dime tú por qué siempre pienso en tí
Por qué nunca te olvidé?
Dime si el tiempo ha causado
Que ya no pienses en mí
(Coro)
Enloquezco sin ti
Voy muriendo sin tu amor
Voy muriendo desgarrando mi piel
We're standin' here
Listening to your lies
Lies you spit from your twisted mouth
But we know what have in your evil mind
Do you think we can swallow that?
-chorus-
We're no fools
We're no slaves
You don't have the control
Your empty words are just a pain in the ass
We don't fear your authority
The crowd is here with a freedom flag
Now we're out off the line
Flashing in the dark
Nobody here walks a step behind
(Chorus)
Hey, Mr. Handsome
Who do you think you're lying to?
Hey, Mr. Asshole
You just want us to call you Mr. President!
Another town, another lie
Another vote for the run
That means more money
For your bank account
We're standing tall
And we won't fall
Come out and see the fuckin' crowd
It's done
Our people are here to break the chains
(Chorus)
-rap-
Burying the poor
You talk about the new democracy
I don't believe
No, I don't believe
I don't believe in your hypocrisy
On the darkest night
In the woods
The king's spirit appeared
He revealed what I already know
King's brother betrayed
By my sword he will pay for his sins
I will take back the crown
You were trying to send me away
I'm back to spill your blood
Lies and crimes
You took over the throne
And seducted the queen
Bring the chariots to this battlefield
To take his bloody corpse away
The light of our people will shine if he dies
My uncle's dark ages are over from now
In the name of my father
In the name of my people
King's brother must die
Vultures fly over him
2, 3, 4!
The light of our people will shine if he dies
My uncle's dark ages are over from now
In the name of my father
In the name of my people
In this lonely night
I am here again
Waiting for you
Wishing you were here
What are you searchin' for?
Why did you leave it all behind?
I can't sleep at night
When the sky turns black
This empty place is darker and scary without you
You leave me, girl
I'm shaking here alone and cold
-chorus-
(Oooh)
Pretty eyes please don't forget me
Remember me once in a while
Don't forget my arms around you
In the backseat of my car
You broke my heart in pieces
I'm still here for you
My arms are still wide open, girl
If you need a place to hide
Memories coming to me
Like the first day of my life
Breakfast in downtown
You and me at the gallery
The love we shared was true, so tell me what went wrong
You took away every piece of my heart
(Chorus)
So you are thinkin' it's over
And you ran away
You left me here
The tears are still falling
Flying south to the land of silver
I see the full moon in the sky
In this black rain I just can't stop!
This empty place is darker and scary without you
You leave me, girl
I'm shaking here alone and cold
(Chorus)
