as per http://blogs.perl.org/users/shlomi_fish/2012/10/please-publish-perl-events-on-the-lwnnet-calendar.html
it would be awesome if act could notify a range of sites and online calendars of upcoming events. at the most basic level send them an email from a template, or perhaps use an API or WWW::Mechanise to fill out a form.
on the above post, a number of sites are listed.
To copy here all the site that were suggested, plus some more:
Act can be enhanced to use these sites' API.. when they have one. Unfortunately, most don't. Take Lanyrd, which makes quite some buzz; its API is "in the pipeline" since 2 years. Other than that, you can't add an event unless you are signed in from Twitter.
LWN.net calendar has no API either, but it's an old-fashioned web site, with a non-Ajaxy web form, so it's easier to automate with WWW::Mechanize.
Heise veranstaltungskalender and Agenda du Libre also have web forms:
YAPC Europe site is generated from http://www.yapceurope.org/events/conferences.yml, which is currently maintained by BooK, who tries to follow when I add new conferences.
The Perl Review's community calendar is on Google Calendar. Don't think there's a way to automate that other tan sending a mail to brian d foy.
I have access to the Perl Reviews calendar as well... I try to keep the calendar up to date.
When we have an easy access to update YEF's conferences.yml I'll write a cronjob that parses YAML and updates the Google Calendar with https://metacpan.org/module/Net::Google::Calendar.
Maybe this can be written as a Act! Plugin as well.
I publish the dates of the events on (most German speaking)
Event dates should be posted on perlmonks as well
