What's the deal with Calendar Categories?
Why do all services and applications seem to handle them differently?
This is a general vent of me, working through all these things and trying to find a reasonable solution!

Often, when I'm consulting with a client and a third-party service provider, I may have the need to bring up a security concern which should be considered, or eliminated, surrounding what the third-party service provider aims to implement. This can be met with a defense of "We have always done it this way and not had a problem yet." which drives me insane!

How I learned to stop worrying and love WhatsApp... not really. This is how I've set up my own XMPP service to be able to talk to WhatsApp using the slidge-whatsapp transport module.
