At first glance it looks somewhat like MediaWiki (the wiki software behind Wikipedia), which also supports creating pages implicitly by linking to them. The markup style also looks similar. Does anybody know how it compares? The MediaWiki interface looks clunkier and you probably will need extensions for some of the stuff Roam does (e.g. like Semantic MediaWiki).

Thanks for tip! Did not help, unfortunately. It seems to connect only for a couple of seconds and then stops charging. After moving the phone a bit it will "reconnect", but again only for a short time. Alas, I do not have access to another phone with wireless charging capability to check where the problem is.

I was in Ikea yesterday and we bought two nightstand lamps with integrated chargers. Did not even realize that yesterday was the first day they were on sale... (in Germany).

Unfortunately, they do not work reliably with my Nexus 4. After putting the phone on the charger it does start charging, but cuts off after a couple of seconds and the charger starts flashing its LED (which is supposed to indicate an error). The phone did not charge at all last night on the charger. I don't know if this is an issue with my Nexus 4, which is already bit beat up, or if there is some kind of incompatibility...

Anybody have any experience with these kind of wireless chargers? Are there compatibility issues?

Thanks for the insight, that's kind of what I expected. Do you know of any tools/products that can perform this kind of analysis? I looked at the whole range of web analytics tools/platforms (Google Analytics, Mixpanel, Piwiki and others), but these are very much focused on web analytics, not so much user behavior inside a (web) application and offer very limited customization. And they usually do not work offline anyway.

Can anybody speak to the difference between Graphite+Grafana and the ELK stack? Are there any fundamental differences in analysis capabilities between these?

We are currently using ELK for doing some lightweight analysis of user behavior (we are using Elasticsearch anyway, so this was the easiest way to get up and running), but as far as I can tell there are some limits to the Elasticsearch/Kibana combination. For example, there seems to be no way to correlate separate events, e.g. how many users that performed action A then performed action B within some time window (or even as the next action). Is this possible with Graphite?
