I'm building a steam power plant simulator for students and trainees that won't cost upwards of $100K for a site license. It also has a plant builder interface, which lets anyone place and connect equipment, piping, instrumentation, and controls. Then, they can run the plant like a real operator would from a control room.
When I was at school for power/stationary engineering, we all wished we could use something like the school's simulator at home. So, maybe I'll get to fill that niche. (And, nothing out there has a do-it-yourself plant builder!)
I have mostly-complete prototypes done for the builder interface and numerical simulator. I like that it keeps the theory that I learned at school nice and fresh.
Also, I bought a gas turbine engine on eBay, and I'm working with a friend to get it running. We got an oil system hooked up yesterday, and we spun it up with the starter motor and a car battery. Lots of fun!
Generates a very healthy income!

I'm interested as to how your algorithm works. My girlfriends family invited me to their Super Six league (I don't watch football) and so I thought about building something like this.
Aside from Cachet, I work on StyleCI (https://styleci.io) which is self-sufficient. StyleCI is a PHP Coding Standards CI that currently works with GitHub. We're working on BitBucket support.
And finally I'm working on a couple of SaaS projects that have yet to launch.

>Please discuss why are you satisfied about it?
I really like Hack, although I am learning some of the assumptions I had about the way types work seem not to be correct, and I'm debugging through nano which is annoying. I don't like that it doesn't support ArrayAccess, but things like shapes and immutable types more than make up for it.
Teaching myself game programming at the low-but-not-bare-metal level of C++ and SDL is satisfying because of the problem solving challenges involved. I kind of know in the back of my mind that I'll probably never come up with a game anyone wants to play, though.

Socialblade's instagram tracking has went down hill in the past few months and also want to avoid the 5 account limit. Nothing crazy complicated, but just something that will make my life much easier.
I am happy with it, I learned quite a bit about Go and I was really able to focus on some interesting aspects of web app development that I would normally not get to work on at my day job.
One other big plus was that I have started using Go at my day job, and it has been a huge help with certain classes of problems.
Also I don't really "enjoy" learning the language so doing something I really enjoy makes it quite nice.
