Programming languages

from the computer article

On the first electronic computers, programmers had to reset switches and rewire computer panels in order to make changes in programs.

Memory Match Puzzles

CRpuzzles Memory Match is two games in one: the solver tries to uncover the picture hidden beneath the paired squares, then comes back and replays the Memory Match Puzzle to try to beat his or her best score for fewest tries. The solver mouse-clicks on two squares; a match results in pieces of the underlying picture being revealed. The CRpuzzles computer counts the total number of attempts required to match all the pairs.
