Nuts are shelled by soaking in water (salt water, probably) for 24 hours, then the nuts are boiled for 5 minutes. The boiling softens the shell, and makes cracking (by hand or machine) much easier. Nuts that are to be sold as blanched or sliced nuts, may be boiled again, before blanching and/or slicing.
A parsec is an astronomical unit of measurement that is equivalent to 3.26 light years distance, or the distance photons will travel in vacuum over the period of 3.26 years.
IPsec is an end-to-end security scheme operating in the Internet Layer of the Internet Protocol Suite, while some other Internet security systems in widespread use, such as Transport Layer Security (TLS) and Secure Shell (SSH), operate in the upper layers at the Application layer.Psec is most commonly used to secure IPv4 traffic. IPsec protocols were originally defined in RFC 1825 through RFC 1829, which were published in 1995. In 1998, these documents were superseded by RFC 2401 and RFC 2412 with a few incompatible engineering details, although they were conceptually identical.
