3 unusual facts about Philip Hazel


Exim

The native school keeps the Exim configuration in one file and external files are only used as data sources; this is strongly influenced by Philip Hazel's preferences and notes on performance as the configuration file is re-read at every exec, which happens post-fork for receiving inbound connections and at delivery.

Philip Hazel retired from the University of Cambridge in 2007 and maintenance of Exim transitioned to a team of maintainers.

Regular expression

Starting in 1997, Philip Hazel developed PCRE (Perl Compatible Regular Expressions), which attempts to closely mimic Perl's regular expression functionality and is used by many modern tools including PHP and Apache HTTP Server.
