I am grateful: The #OpenWebCalendar is one of the #opensource projects that get funded by @NGIZero this year!
We have funding for a lot of the #Python stack that it takes to build #calendar applications and #share the appointments via #ICS files: #icalendar #XWRTimezone #RecurringIcalEvents #ICSQuery #Mergecal #Caldav

#public #funding of #opensource #critical infrastucture goes a long way.
Read an opinion on how @nlnet's funding of #Python's calendaring stack does not only benefit end users through the #OpenWebCalendar but contributes to a vibrant #digital, #decentralized and self-governed EU #economy. #Collaboration and #competition in the digital market require open-source and public standards.

Thanks to the funding by @nlnet, I added #event sign up via email to the #OpenWebCalendar. In this tutorial, I show how to enable others to sign up to your events on your @nextcloud #calendar.

I am creating a series of #videos about the #OpenWebCalendar which you can embed into your #website with privacy and customization features. I wanted to use @peertube but I do not have an instance for that. Who could I ask, is there an instance that would host some technical tutorials? 
I use #youtube for now but I would like an #alternative here.

The #OpenWebCalendar has a new #UI!
You can head over to https://open-web-calendar.hosted.quelltext.eu and try it out:
- #edit the #calendar AND see it updating
- #encryption protects #private calendars and the #password
- #CalDAV support
- Change the size to see how it works on other screens
In the picture, the URL to the Personal CalDAV calendar is encrypted and the events show up.
Technically, I really enjoyed #flexbox and #CSS variables i.e. for the dynamic resizing.
The #OpenWebCalendar now supports #encryption of #calendar URLs to protect sensitive data like passwords.
Now, you can publish an #event calendar on your website even if you require a password for it - without anyone seeing the password.
Try it out: Head over to https://open-web-calendar.hosted.quelltext.eu and click the encrypt button!
Thanks to @nlnet for the funding!
I got the shirt from #tidelift for raising the security of several software packages for #Python and #icalendar. This, #rfc5545 is used in so many places to exchange calendar events freely.
You can directly support my work, too: https://open-web-calendar.quelltext.eu/contributing/
I completed all the tests to #Tidelift the #opensource #python #package x-wr-timezone.
Tidelift helps your company to secure the supply chain for the free software dependencies of your solutions. It is worth checking out if you care about #foss #sustainability.
I just installed #UptimeKuma
https://github.com/louislam/uptime-kuma
It was relatively easy to get notifications to #signal and #telegram to tell me if my #website and #webservice is running.
You can pull the container with #docker and #docker_compose.
The reason is that #uptimerobot is switching to a paid plan for commercial services.
Within an few minutes, I also added a #status #page for the #OpenWebCalendar: https://kuma.hosted.quelltext.eu/status/open-web-calendar
#icalendar #OpenWebCalendar #icsquery and many other #Python libraries are participating this #October in the @hacktoberfest!
Whether you are new to #opensource or know it for a while: You can contribute to a lot of projects on #GitHub and #GitLab. Join us!
We have released a new version of #RecurringIcalEvents - event times calculation for #icalendar in #Python. This release includes the rare case of rescheduling all future events as well as being able to edit the content of all future events. In the specification it is RANGE=THISANDFUTURE.
A new release of the #OpenWebCalendar will support this. If you would like to help us, if you have #LotusNotes installed, look here: https://github.com/niccokunzmann/python-recurring-ical-events/issues/184
What is in .ics files? These calendar files can now be inspected with a new command line tool: ics-query
https://pypi.org/project/ics-query/
Due to the power of #OpenSource, this tool was easy to create and has a high quality and compatibility from the start. The calculation module python-recurring-ical-events is more than five years old and has seen many improvements and contributions since.
The #OpenWebCalendar is now also available as a #Python package on #PyPI. This makes it easy to install!
Check out the documentation:
https://open-web-calendar.quelltext.eu/host/pypi/
#Gancio also exports the events as #ics and so one can embed and merge several timelines using the #OpenWebCalendar. https://open-web-calendar.quelltext.eu. That is how I found Gancio - https://gancio.org.

@seddon @davidoclubb I am planning to come, too. I can offer to talk about FOSS-development, the #OpenWebCalendar, #fdroid and its ecosystem, translating FOSS software to #Welsh and more.
We also have a #matrix chat if you like to join: #foss-wales:matrix.org
See you there
