On JumpHigher [1], an app that helps you improve your vertical leaps, just using your phone camera. It's functional already, but very early, the algorithm took quite a while to nail ( still far from perfect ).
I'm a CEO of a small consulting company, and I love working with startups ( or hate working with huge companies, matter of perspective ), and I always thought that to be better at that we have to be able to launch our own stuff.
Also, I never launched anything solo, working alone is hard for me so this was a challenge. I want to continue working on it on the side for a while.
The main audience for now would be basketball players that want to dunk, or anyone that wants a good leg workout and track the progress.
Have you thought about sub Ghz mesh networking like 6lowpan with TI CC1310? If you don't need that much computing power then it's a good option, with way longer battery life.
Z-transform is very similar to Fourier or Laplace transform, but in discrete time. These things are not that hard, if you get FFT already then you can get there if you want.
In high level play you have to manage your land, the hard thing is how to find the optimal route to collect your army: It's advisable to take around 15-18 turns to collect your army from an area and attack in the remaining 10-7 turns, so you can attack before the enemy numbers increase. In high level 1v1 play what matters most is the area you have, if you can get +1 area per 25 rounds from your enemy you'll probably win.
But! As both of you collect more and more area it gets really time consuming and after a point you just can't collect your army optimally. I'd argue that the biggest difference between skill levels at the highest levels is how efficient the collecting is. At that point you'll need cities. Always look for the opponent's counter to know how many cities your opponent has.
Not that it matters but I was a top 5 1v1 player quite a while ago.
One data point: I've been to couples therapy quite a few years ago and we've been getting better and better ever since.
From my experience a priest would go into that discussion with the goal of keeping the couple together, while the therapist would want ( a good one ) the best for them, whatever that may be. If your goal is to stay together with someone don't go to a therapist.
