I guess our (Polish) bomba kryptologiczna (cryptological bomb) was a product of country with much less spare resources than UK and USA, who made their own "bombes" few years later (strange coincidence of names, isn't it). http://en.wikipedia.org/wiki/Bomba_(cryptography) http://en.wikipedia.org/wiki/Bombe I guess, with few more years of peace, our efforts could possibly lead to much more advanced devices. But at the same time, few years later all sides would have been better prepared, making a conflict even more brutal. I find the whole Enigma-breaking story quite interesting in many aspects, not last of which is description of such efforts by western specialists (some of those resemble popular detective/spy stories, with idealistic factory workers and whatnot). It's interesting to think why our own folk were not included in efforts made by Bletchley (actually, they were left to do as they pleased, to speak it euphemistically, given that they were often chased by Germans throughout occupied Europe, in hope to beat some secret out of them). From what I've gathered so far, up to early 1970-ties the popular knowledge was that Enigma was unbreakable, and at the same time some derivative of it had been sold to third world countries (I don't remember who sold them, UK or USA). Funny. But also a bit disgusting, if anybody asks me, because after the 70-ties not much have changed. Maybe I demand too much, however, since modern people seem to treat past merely as a source of romantic entertainment, at best. Our own success story, including first breakings of E* with pen and paper (yeah, in times when everybody else was lying belly up in front of "impossible") in early 1930-ties (Grill), leading to first attempt to mechanize it in 1935 (Cyclometer) is, I'm afraid, largely swiped under the rug. http://en.wikipedia.org/wiki/Grill_(cryptology) http://en.wikipedia.org/wiki/Cyclometer So, Bomba was great stuff but it seems to me, we were doing it with pen, paper and brain for a while :-). BTW, if anybody here would rather read a book, I liked Neal Stephenson's Cryptonomicon. It is a bit naive from nowadays' perspective, but quite good and maybe even educating read. Not about Enigma, or rather not only about it. Most movies nowadays fail to catch my attention, probably because I tend to read about them before watching, which results in dissatisfaction :-). And if they treat about anything technical, boy, I am disgusted even before reading (but I am also disgusted by Lord otR, so perhaps I am just disgusted with everything - um, not with everything, so those must be mediocre and deserve contempt). -- Regards, Tomasz Rola -- ** A C programmer asked whether computer had Buddha's nature. ** ** As the answer, master did "rm -rif" on the programmer's home ** ** directory.
