Calendar Indicator, an Ubuntu AppIndicator for Google Calendar, was updated to version 0.2.0, receiving some important bug fixes, including a fix for the calendar events not showing up in the indicator menu under Ubuntu 13.10 Saucy Salamander.

The new version brings options to add, edit and delete Google Calendar events as well as to create new calendars. Until now, Calendar Indicator would only display Google Calendar events in the indicator menu and through notifications. There's also a new option to select the calendar to be used from all your Google calendars (or you can select all of them).

You can use Lightning to get a calendar that's fully integrated with Thunderbird, but what about Google Calendar synchronization? Well, there's an extension called "Provider for Google Calendar", which lets Lightning read and write events to Google Calendar.

You can already do that with Evolution and Indicator DateTime, but there are some differences: firstly, the obvious: you don't need Evolution to use Calendar Indicator. And secondly, Calendar Indicator displays the next 10 upcoming Google Calendar events at once, so you don't have to scroll through dates to see your Google Calendar events.

Back when we've posted about integrating Google Calendar with GNOME Shell (without Evolution), some of you didn't know how to do this with Evolution. So here is how to set up Evolution to display Google Calendar events in the Unity / GNOME Shell calendar.

The python script uses GNOME Keyring for storing your password and automatically fetches new Google Calendar events when you click the GNOME Shell calendar on the top panel. For now, you can't configure which calendar is imported (all are used) and there's no configuration GUI (but it's still very easy to use).

You can already do this through Evolution, but using this script, Evolution is not required.

This post explains how to display Google Calendar on your Desktop using Conky and Gcalcli (a tool you can use to manage Google Calendar via the command line).

If you already have a Conky instance running and want to also display Google Calendar on your desktop using Conky, see this how-to on running multiple Conky instances.

I was just reading about GoogleCL at Lifehacker and after testing it for a while I realized it's actually very useful.

Using GoogleCL - a command line tool to manage all the Google services -, you can upload photos to your PicasaWeb albums, post to your Blogger blog, modify Google Calendar events, add contacts, manage your Google Docs (upload, delete, and so on) and even upload videos to YouTube. Unfortunately it doesn't come with support for Gmail.
