“Side Channels” is three years old! It has been an interesting year, albeit with little blogging. One of the highlights of the past year was my four week trip to Brazil in April. Good food, weather, people. I visited Rio de Janeiro (Ilha Grande, Rio), Pernambuco (компютриландшафтRecife, Ilha de ItamaracÃ¡, Porto de Galinhas), and Rio Grande do Sul (Porto Alegre, and the great town of Vacaria).
In Recife there is a very long beach stretch along a neighborhood called Boa Viagem. It is a popular destination, but used to be more so until in the early 1990s when ecosystem disruption due to development has driven sharks to Boa Viagem beaches. Shark attacks on humans have then become much more frequent. I found this sign interesting as one rarely sees this kind of language on signs, and it was unexpected there in Brazil’s Northeast. Note that the Portuguese portion doesn’t evoke statistics and simply says “Danger: area susceptible to shark attacks.” (Presumably because it is common knowledge over there and the risks are well known).
