In order to enable an iCal export link, your account needs to have an API key created. This key enables other applications to access data from within Indico even when you are neither using nor logged into the Indico system yourself with the link provided. Once created, you can manage your key at any time by going to 'My Profile' and looking under the tab entitled 'HTTP API'. Further information about HTTP API keys can be found in the Indico documentation.
Additionally to having an API key associated with your account, exporting private event information requires the usage of a persistent signature. This enables API URLs which do not expire after a few minutes so while the setting is active, anyone in possession of the link provided can access the information. Due to this, it is extremely important that you keep these links private and for your use only. If you think someone else may have acquired access to a link using this key in the future, you must immediately create a new key pair on the 'My Profile' page under the 'HTTP API' and update the iCalendar links afterwards.

COLLOQUIUM: Geometry, light and a wee bit of magic
(University of St Andrews, UK)

Many mass-produced everyday products of modern technology would appear
to be completely magical to our ancestors: mobile phones, television,
computers, electric light, cars, etc. Some devices that are still
perceived as magical or mysterious are about to appear in the laboratory
and are not so mysterious after all.
For example, the first prototype of
an electromagnetic cloaking device has been recently made at Duke
This device makes an object invisible to microwave radiation
of a single frequency and polarization.
At Harvard University, first
vital steps towards levitating objects on the forces of the quantum
vacuum have been made.
At St Andrews, we observed first indications of
artificial black holes in the laboratory, using extremely short light
pulses in photonic-crystal fibres.
Invisibility devices, quantum forces
and optical black holes have two things in common: they represent
applications of Einstein's general relativity in Maxwell's
electromagnetism and their practical demonstrations are made possible by
I will try to elucidate the scientific principles
acing behind the scenes of such "pure and applied magic".
