 Some people may haven't yet realized that we've got plenty of open-source tools to store, analyze, link and visualize billions of data rows quickly and with much ease. Imagine what people with a multi-billion budget are able to employ. To give you a small scale example, how transparent anyone's little life and habits become, I've created a [[https://apollo.open-resource.org/flight-control/vfcc/#/dashboard/db/aquarius-hab-environment-indoor|dashboard]] which doesn't show many metrics yet (more are in the process) but it's more than enough, if you learn how to interpret the graphs. The data you see there is mostly generated by two spark-cores which are deployed here. Big/Open-Data/Cloud technology is not the problem itself, it's our culture/society, which obviously isn't ready for it. Some people may haven't yet realized that we've got plenty of open-source tools to store, analyze, link and visualize billions of data rows quickly and with much ease.

Access- and Cloud-Provider are no exception. All of them can be tricked, coerced or forced to "assist" in one way or another. No matter what anyone promises, from this point on, they all have to be considered compromised.+In the year 2014, in a post [[http://spectrum.ieee.org/telecom/security/the-real-story-of-stuxnet|Olympic Games (Stuxnet) & Nitro Zeus]], [[http://www.heise.de/extras/timeline/|Snowden]] & [[http://www.zdnet.com/unsealed-docs-show-what-really-happened-with-lavabit-7000021489/|Lavabit]] era, we have no other choice but to come out of our state of denial and simply accept the fact, that every commercial entity can be compromised through multiple legal, administrative, monetary, social/personal or technological levers.

No matter what anyone promises, from this point on, they all have to be considered compromised.
  
 The current software implementation (firmware- and server-side) has no concept of mesh/p2p or direct networking/communication. All Spark-Cores need a centralized spark-server for Control & Communication. Also, the Spark.connect() routine unfortunately has no timeout (yet?), the Core might hang indefinitely, which could be a big problem, even if your particular code doesn't require to connect to the cloud because after you call Spark.connect(), **your loop will not be called again until the Core finishes connecting to the Cloud**. This might happen if your WiFI or internet access is offline. The current software implementation (firmware- and server-side) has no concept of mesh/p2p or direct networking/communication.
