MLMUG Journal

The Main Line Macintosh User Group published one article in MLMUG Journal on Time Machine. Not sure if I should call this science fiction or computer science. In theory, they published some others as well, but I haven’t found them Continue reading MLMUG Journal

Codes, cyphers, and the National Cryptologic Museum

Outside the National Cryptologic Museum gift store is this replica of the Rosetta Stone. Created around 196 BC, it displays a decree from an Egyptian king, written in Egyptian hieroglyphs, Demotic script and ancient Greek. Discovered by a French soldier during France's invasion of Egypt in 1799, it provided the key to unlocking Egyptian hieroglyphs, much as modern code breakers look for keys in breaking coded texts. The real Rosetta Stone is on display at the British Museum in London.

Located at the edge of Fort Meade, Maryland, in an old, nondescript motel, is the National Cryptologic Museum. Admission is free, and with that admission you can explore how the worlds of communications, mathematics, and security intersect in cryptology.
