Television series executive producer Russell T Davies wrote in Doctor Who Magazine # 356 that there is no connection between the War of the books and the Time War of the television series.

# An SSL / TLS connection is managed by the first front machine that initiates the SSL connection.

# For SSL with mutual authentication, the SSL / TLS session is managed by the first server that initiates the connection.

# With mutual SSL / TLS, security is maximal, but on the client-side, there is no way to properly end the SSL connection and disconnect the user except by waiting for the SSL server session to expire or closing all related client applications.

# it counts the factors that connect or link the legal issues to the laws of potentially relevant states and applies the laws that have the greatest connection, e. g. the law of nationality ( lex patriae ) or domicile ( lex domicilii ) will define legal status and capacity, the law of the state in which land is situated ( lex situs ) will be applied to determine all questions of title, the law of the place where a transaction physically takes place or of the occurrence that gave rise to the litigation ( lex loci actus ) will often be the controlling law selected when the matter is substantive, but the proper law has become a more common choice.

The reissue of the original 1965 version of " Unchained Melody " hit # 13 on the Hot 100 in 1990 in connection with the film, and the following re-recording of the song by The Righteous Brothers hit # 19 on the Hot 100 and was certified Platinum by the Recording Industry Association of America ( RIAA ).

# In an open-network-architecture context, the fundamental underlying connection of an enhanced service provider ( ESP ) to and through the operating company's network including an ESP access link, the features and functions associated with that access link at the central office serving the ESP and / or other offices, and the transport ( dedicated or switched ) within the network that completes the connection from the ESP to the central office serving its customers or to capabilities associated with the customer's complementary network services.

# The user trusts that the browser software correctly implements HTTPS with correctly pre-installed certificate authorities.

# The user trusts the certificate authority to vouch only for legitimate websites.

# Either the intervening hops on the Internet are trustworthy, or the user trusts that the protocol's encryption layer ( TLS / SSL ) is sufficiently secure against eavesdroppers.

# For performance reasons, static content that is not specific to the user or transaction, and thus not private, is usually delivered through a non-crypted front server or separate server instance with no SSL.

# ICQ Game Center — A games platform that enables the user to play with and / or against other users.

# Factor analysis is similar to PCA but allows the user to extract a specified number of synthetic variables, fewer than the original set, leaving the remaining unexplained variation as error.

# Redundancy analysis is similar to canonical correlation analysis but allows the user to derive a specified number of synthetic variables from one set of ( independent ) variables that explain as much variance as possible in another ( independent ) set.

# Active learning: Instead of assuming that all of the training examples are given at the start, active learning algorithms interactively collect new examples, typically by making queries to a human user.

# Tutorial: A tutorial approach is considered the most useful for a new user, in which they are guided through each step of accomplishing particular tasks.

# Thematic: A thematic approach, where chapters or sections concentrate on one particular area of interest, is of more general use to an intermediate user.
