A-0 System
The A-0 system (Arithmetic Language version 0), written by Grace Hopper in 1951 and 1952 for the UNIVAC I, was the first compiler ever developed for an electronic computer. The A-0 functioned more as a loader or linker than the modern notion of a compiler. A program was specified as a sequence of subroutines and arguments. The subroutines were identified by a numeric code and the arguments to the subroutines were written directly after each subroutine code. The A-0 system converted the specification into machine code that could be fed into the computer a second time to execute the said program.
The A-0 system was followed by the A-1, A-2, A-3 (released as ARITH-MATIC), AT-3 (released as MATH-MATIC) and B-0 (released as FLOW-MATIC).
The A-2 system was developed at the UNIVAC division of Remington Rand in 1953 and released to customers by the end of that year. Customers were provided the source code for A-2 and invited to send their improvements back to UNIVAC. Thus A-2 was an early, and perhaps the first, example of free and open-source software.
Division by zero
In mathematics, division by zero is division where the divisor (denominator) is zero. Such a division can be formally expressed as a/0 where a is the dividend (numerator). In ordinary arithmetic, the expression has no meaning, as there is no number which, multiplied by 0, gives a (assuming a≠0), and so division by zero is undefined. Since any number multiplied by zero is zero, the expression 0/0 also has no defined value; when it is the form of a limit, it is an indeterminate form. Historically, one of the earliest recorded references to the mathematical impossibility of assigning a value to a/0 is contained in George Berkeley's criticism of infinitesimal calculus in The Analyst ("ghosts of departed quantities").
There are mathematical structures in which a/0 is defined for some a such as in the Riemann sphere and the real projective line; however, such structures cannot satisfy every ordinary rule of arithmetic (the field axioms).
In computing, a program error may result from an attempt to divide by zero. Depending on the programming environment and the type of number (e.g. floating point, integer) being divided by zero, it may generate positive or negative infinity by the IEEE 754 floating point standard, generate an exception, generate an error message, cause the program to terminate, result in a special not-a-number value, freezes via infinite loop, or a crash.

My Bad
by: I15[I15:]
Uh check this out ma,
Look I didn't mean to hurt you,
But I thought we had an understanding about how it's gonna be,
You know, (Yeaah Mann!)
You roll through or I roll through, (F to the A-B)
And we just do what we do,
You know what I'm saying, (I-15)
I ain't looking for no relationship,
But I'm goin ahead let my boy Fab holla at you...
[Fabolous:]
Yeah, this is real talk,
I told you there was others,
Now we go to war like soldiers with each other,
I'm trying to let it go not hold you like a lover,
See I'm simply P-I-M-P,
So I gotta stable-a chicks,
Unable to pick,
A babe I can lick out,
And I be labelled a trick,
If you down you can roll and if you not you can stroll,
It's just that easy,
When F-A-B's here...
[I15:]
Girl you got it twisted,
You already know how I get down,
Now you out here trippin',
On some sh*t that we already talked about,
I just want to hit it,
And you said that was cool with you,
Now you here crying to me,
Saying you want to be with a player like me,
That ain't cool...
[Chorus: I15]
My bad, didn't mean you to make you want it like that,
And I hang up, and you call me right back,
It's like you don't even know how to act, (What's going on...)
My bad, baby girl we barely even friends,
I just like to smash it now and then,
Now you got me scared to hit it again,
[I15:]
Now I don't mean to hurt you,
But it's not like you didn't know,
From the beginning,
Now you saying that you can't stand to be without me,
Now girl you talking crazy,
I'm not trying to deal with you,
Gonna keep it real with you,
Shorty I don't want to be with you...
[Chorus: I15]
My bad, didn't mean you to make you want it like that,
And I hang up, and you call me right back, (Back...)
It's like you don't even know how to act, (What's going on...)
My bad, baby girl we barely even friends, (Friends...)
I just like to smash it now and then,
Now you got me scared to hit it again, (Yeah...)
[Fabolous:]
Now you know I come through every now and then,
To see how you been couple of thou' to spend,
But you knows how it goes,
Girls act like you suppose to propose... After a month,
But I choose to refuse,
I'm the kind of the man that do's what I choose,
Whenever I want,
And it's never to front,
It's just to let you know,
It's cheaper to keep her,
I'll still will let you go, girl...
[I15:]
I've lost my patience,
With these ultimatums,
Tryin' to lock me down like incarceration,
I don't cuff 'em when I grab 'em,
I thug them with the passion,
Still running from the last one,
They tugging on my ass clip,
I don't what it is, I'm cool on that "Might Be" tip,
I ain't Damon, I'm too young for a wife and kids,
I kick it "if we", like Vivica and 50,
Like Fab said simply, we P-I-M-P...
[Chorus x2: I15]
My bad, didn't mean you to make you want it like that,
And I hang up, and you call me right back,
It's like you don't even know how to act,
My bad, baby girl we barely even friends,
I just like to smash it now and then,
