PlayDrone indexed and decompiled 1,100,000 Google Play applications. The source revealed a lot of applications were including OAuth tokens in applications (e.g. AWS tokens, FB tokens); a critical security hole. Very interesting paper and presentation.
Our disk size shrank to 10% of stock mongodb size.
The migration is easy now that they've released a tool to replicate from a stock mongo to TokuMX. They also do have commercial support that we've paid for and their team has been incredibly helpful and responsive.
We moved to TokuMX (http://www.tokutek.com/products/tokumx-for-mongodb/) recently and saw a 2x improvement in response times. They've swapped out mongo's backend with their fractal tree storage engine which is MVCC. Definitely worth checking out.
You don't need to create an SSH account or let your friends connect to your machine. Your session is proxied through the tmate.io server (safely) so that you can avoid the headache of opening up a connection.
I've tried this out and it is dramatically better then other alternatives, full screen-sharing suffers from latency issues (screenhero, logmein, etc...) and sharing an ssh session is a pain to get setup (e.g. wemux). I highly recommend it.
This reminds me of a side project I've been working: http://autobot.io. Idea is to have a chat bot in your email that can handle mundane tasks. I started with scheduling as that's a particularly acute pain-point for me.
