2008-08-05T09:13:00.005+03:00 Packing, on my way to a family vacation in Anatalya, Turkey.
Following an interesting discussion yesterday about performance metrics -- it turns out that definition of latency in event processing network is quite tricky. The reason is that an event can move in multiple paths over the network, in some it is filterred out, in some it just getting into internal state of agent since it does not complete a pattern, and in some it may complete a pattern and trigger reaction, thus there are various ways to define the metrics here. This is important since optimization has to take into account the goal function - what is being optimized. More discussion on this area -- after I'll return. I'll be out of touch for a week.
VACATION(1) General Commands Manual VACATION(1)NAME
vacation - return ``I am on vacation'' indication
SYNOPSIS
vacation -I
vacation user
DESCRIPTION
Vacation returns a message to the sender of a message telling that you are on vacation. The intended use is in a .forward file. For exam-
ple, your .forward file might have:
eric, "|vacation eric"
which would send messages to you (assuming your login name was eric) and send a message back to the sender.
Vacation expects a file .vacation.msg in your home directory containing a message to be sent back to each sender. It should be an entire
message (including headers). For example, it might say:
From: eric@ucbmonet.Berkeley.EDU (Eric Allman)
Subject: I am on vacation
Delivered-By-The-Graces-Of: the Vacation program
I am on vacation until July 22. If you have something urgent,
please contact Joe Kalash <kalash@ucbingres.Berkeley.EDU>.
--eric
This message will only be sent once a week to each unique sender. The people who have sent you messages are kept in the files .vaca-
tion.pag and .vacation.dir in your home directory. The -I option initializes these files, and should be executed before you modify your
.forward file.
If the -I flag is not specified, vacation reads the first line from the standard input for a UNIX-style ``From'' line to determine the
sender. If this is not present, a nasty diagnostic is produced. Sendmail(8) includes the ``From'' line automatically.
No message is sent if the initial ``From'' line includes the string ``-REQUEST@'' or if a ``Precedence: bulk'' or ``Precedence: junk'' line
is included in the header.
