Last week, I heard but did not see the CF18 jets that did a flyover of Ottawa to commemorate David Johnston becoming Canada’s new Governor General. While I believe that the monarchy is a dated institution that ought to be scrapped, I do appreciate one modern touch Mr. Johnston brought to his office, in the form of a geeky mystery built into his coat of arms. Along the bottom is a palindromic binary sequence: 110010111001001010100100111010011.
Converted to decinal representation, that is: 6830770643. In hexadecimal, it is: 1972549d3.
The CBC Inside Politics blog has been puzzling over the sequence, without success. So has Slashdot. Whatever the meaning of the string is, it seems to be better concealed than the MD5 hash in the emblem of the United States Cyber Command.
