dear wikipedia, will you marry me? I'm fairly certain I'll always love you... or at least some future version of you. by Jan 31
The history of the Internet began with the development of computers in the 1950s. This began with point-to-point communication between mainframe computers and terminals , expanded to point-to-point connections between computers and then early research into packet switching . Packet switched networks such as ARPANET , Mark I at NPL in the UK , CYCLADES , Merit Network , Tymnet , and Telenet , were developed in the late 1960s and early 1970s using a variety of protocols . The ARPANET in particular led to the development of protocols for internetworking , where multiple separate networks could be joined together into a network of networks. 1974 ABC interview with Arthur C.

Bit - Wikipedia, the free encyclopedia
A bit (a contraction of binary digit ) is the basic unit of information in computing and telecommunications ; it is the amount of information stored by a digital device or other physical system that exists in one of two possible distinct states . These may be the two stable states of a flip-flop , two positions of an electrical switch , two distinct voltage or current levels allowed by a circuit , two distinct levels of light intensity , two directions of magnetization or polarization , the orientation of reversible double stranded DNA , etc. In computing , a bit can also be defined as a variable or computed quantity that can have only two possible values . These two values are often interpreted as binary digits and are usually denoted by the numerical digits 0 and 1. The two values can also be interpreted as logical values ( true / false , yes / no ), algebraic signs ( + / − ), activation states ( on / off ), or any other two-valued attribute.All 128 ASCII characters, including non-printable characters (represented by their abbreviations). The 95 ASCII graphic characters are numbered from 20 hex to 7E hex (decimal 32 to 126). The space character is considered a non-printing graphic. [ 1 ] [ 2 ] The American Standard Code for Information Interchange ( ASCII , pronunciation: / ˈ æ s k i / ASS -kee ; [ 3 ] ) is a character-encoding scheme originally based on the English alphabet .

Flow chart of an algorithm ( Euclid's algorithm ) for calculating the greatest common divisor (g.c.d.) of two numbers a and b in locations named A and B. The algorithm proceeds by successive subtractions in two loops: IF the test B ≤ A yields "yes" (or true) (more accurately the number b in location B is less than or equal to the number a in location A) THEN the algorithm specifies B ← B − A (meaning the number b − a replaces the old b ). Similarly IF A > B THEN A ← A − B.

ngh... hate to look a gift horse in the mouth here, but, this guy's demeanor is messing with my enthusiasm. anyone make it past the first video? if so does it get any better or make you wish you'd never heard of an algorithm? by Jan 31
Eve Sussman’s experimental cinema project whiteonwhite:algorithmicnoir uses a computer to build a movie out of 3,000 video clips, 80 voiceovers and 150 pieces of music. Though it makes choices in largely random fashion, the computer is surprisingly adept at editing together a pretty good movie. Sometimes. whiteonwhite played three shows at the Sundance Film Festival (it has also been performed in New York and will soon travel to Berlin and Santa Fe , New Mexico). Of the three Sundance screenings, Sussman and co-writer Jeff Wood described one as so-so, one somewhat painful to watch, and one as outstanding. “Sometimes it works like we expect it would….

Scratch is an early computer language learning environment enabling young beginners to get results without having to learn syntactically correct writing first. Created by the MIT Media Lab , it is intended to motivate for further learning through playfully experimenting and creating projects, such as interactive animations etc. The name Scratch derived from the turntablism's technique of scratching , [ 1 ] and stresses the similarity of the process of programming to the process of mixing/scratching instead of its similarity to the processes of writing (i.e. scripting ). Scratch is available for Windows , Mac OS X , and Linux .
Scratch (programming language) - Wikipedia, the free encyclopedia
In computer programming a statement can be thought of as the smallest standalone element of an imperative programming language . A program written in such a language is formed by a sequence of one or more statements. A statement will have internal components (e.g., expressions ). Many languages (e.g. C ) make a distinction between statements and definitions, with a statement only containing executable code and a definition declaring an identifier . A distinction can also be made between simple and compound statements; the latter may contain statements as components.
Statement (computer science) - Wikipedia, the free encyclopedia
A statement separator is used to demarcate boundaries between two separate statements. A statement terminator is used to demarcate the end of an individual statement. Line continuation is a convention in languages where the newline character could potentially be misinterpreted as a statement terminator. In such languages, it allows a single statement to span more than just one line. MATLAB : The ellipsis token need not be the last characters on the line, but any following it will be ignored. [ 5 ] (In essence, it begins a comment that extends through (i.e. including) the first subsequent newline character. Contrast this with an inline comment, which extends until the first subsequent newline.)
Comparison of programming languages (syntax) - Wikipedia, the free encyclopedia
A programming language is an artificial language designed to communicate instructions to a machine , particularly a computer . Programming languages can be used to create programs that control the behavior of a machine and/or to express algorithms precisely. The earliest programming languages predate the invention of the computer , and were used to direct the behavior of machines such as Jacquard looms and player pianos .

Boolean expression - Wikipedia, the free encyclopedia
In computer science , a Boolean expression is an expression in a programming language that produces a Boolean value when evaluated, i.e. one of true or false . A Boolean expression may be composed of a combination of the Boolean constants true or false , Boolean-typed variables, Boolean-valued operators, and Boolean-valued functions . [ edit ] Boolean operators Programmers will often use a pipe symbol (|) for OR, an ampersand (&) for AND, and a tilde (~) for NOT.Conditional (programming) - Wikipedia, the free encyclopedia

I love all of the opportunities to learn and explore that are so available. It is such a rush as my mind is blown away by the free education that is growing significantly. Very interesting to think about what it might look like in 3-5 years. by Feb 8
I am absolutely in love with these people (and the free information movement in general) for taking the time to create these. It just blows my mind that so much more and more is becomming available for anyone who wants to learn... and for FREE, and IN A FUN WAY!
