How do I disable notifications/reminder and set events to free time with Perl's ICal::Entry?
How do I disable notifications/reminder and set events to free time with
Perl's ICal::Entry?
Unforunately my university was too lazy to make a google calendar or .ics
for our public events. Instead they choose to wirte us an email with a
formatted text file containing a list of the dates. I have a Perl script
to convert said list, into an iCalendar (.ics) file. I want to import that
.ics into my google calendar later.
So far the script works very well but now I want to disable the standard
notifications (E-Mail and PopUp) and set the events to be free time
(instead of default busy). The problem is, that I don't get anything
usefull out of the documentation for Data::ICal::Entry::FreeBusy and
Data::ICal::Entry::Alarm::Display. Be so kind an provide me with the right
properties to add to the $event->add_properties(...) line in the script
below:
#!/usr/bin/perl -w
# Converts a specially formated text file (list of events) into an .ics
# (iCalendar) file for import into Google-Calendar or other calendar
# applications.
use Date::ICal;
use Data::ICal;
use Data::ICal::Entry::Event;
# Read file into one long string
open FILE, $ARGV[0] or die "Couldn't open file: $!";
my $fstring = join("", <FILE>);
close FILE;
# Prepare calendar
my $calendar = Data::ICal->new();
$calendar->add_properties( method=>"PUBLISH",);
# Add events depending on what was found in file
@events = split("\n\n", $fstring);
foreach $eventstring (@events) {
$eventstring =~ s/(\d+\.\d+\.\d+)//; # remove date from the string
$datestring = $1; #+but save it for processing:
($day, $month, $year) = split(/\./, $datestring);
$title = ( split /\n/, $eventstring )[1];
my $event = Data::ICal::Entry::Event->new();
$event->add_properties(
summary => "Kolloquium: $title",
description => $eventstring,
dtstart => Date::ICal->new( year=>"20$year", month=>$month,
day=>$day, hour=>17, min=>15 )->ical,
dtend => Date::ICal->new( year=>"20$year", month=>$month,
day=>$day, hour=>18, min=>15 )->ical,
dtstamp => Date::ICal->new( epoch => time )->ical,
# MISSING HERE: Right FREEBUSY and ALARM properties. PLEASE HELP!
);
$calendar->add_entry($event);
}
print $calendar->as_string;
Thank you kindly!

python - first alphabetic character, last, and pull the string in between
python - first alphabetic character, last, and pull the string in between
Strip string and return lowercase version of result
Return a lowercase version of the word with all non-alphabetic symbols
stripped away from the boundaries, but with such symbols remaining in the
interior of a word.
Precondition: wd is a string Postcondition: returns 'stripped' string in
lowercase
Typical examples of this behavior include:
>>> word_strip("don't")
"don't"
>>> word_strip('end.')
'end'
>>> word_strip('jack-o-lantern')
'jack-o-lantern'
>>> word_strip('"Stop!"')
'stop'
>>> word_strip('&%^$*%*%"')
''
>>> word_strip('hello there!!')
'hello there'
Code:
import string
def word_strip(wd):
alpha = 'abcdefghijklmnopqrstuvwxyz'
for i in range(0,len(wd)):
if wd[i] == alpha:
a = wd.find(alpha)
# locate last desirable character
b = wd.endswith(alpha)
# return an intentionally lowercase stripped word
wd = wd[a:b]
wd = wd.lower()
return wd

How can I select and display the maximum (and minimum) values from among several fields in a single record in mysql using php
How can I select and display the maximum (and minimum) values from among
several fields in a single record in mysql using php
I have a table which lists several tours and for each tour there are
several categories of accommodation types with different prices, along
with a lot of other fields such as dates, deadlines etc. It was easy to
set things up to display the array showing the tour, dates, deadlines but
I also want to select and display the maximum (and minimum when not 0)
accommodation rates for each tour. I may not be understanding some of the
answers I'm seeing but most seem to be looking for max values within a
field rather than across fields. I'm assuming once I know how to find the
max value, finding the min value would be the same basic procedure.
the abbreviated table structure with example data is:
id tourID RmA RmB RmC RmD ...other fields...
1 mb 600 450 550 300
2 kr 900 0 600 450
3 ww 500 650 550 600
4 wf 750 300 400 500
What I'd like to add to my current display is:
Tour Rates
mb 300 - 600
kr 450 - 900
WW 500 - 650
wf 300 - 750
I apologise if I'm repeating a frequently asked question, but it may be
that I haven't googled my question in a manner to find the appropriate
answer.

Does Ubuntu Terminal Run In the background?
Does Ubuntu Terminal Run In the background?
I have a question?
If I am in the middle of using the terminal, say to apt-get something;
If I click the x / close button, does the Terminal continue to run in the
background?
To afraid to try it, cause I don't want to have to start the process all
over again...
Has anyone accidentally done it?
