It depends... if you are picky and can sell yourself well, 80+/hour as a senior. Unsure of junior rates but maybe 50+. PHP may be less in demand on angellist in particular though as compared to JavaScript/Ruby
12 hours/week doesn't sound like enough time to make any money via appstore to me, as some are suggesting. It's just enough time to freelance a bit though! You can find part time freelance work without an established network pretty easily actually. I've done this successfully for web dev work several times:
1) search angellist jobs section for companies looking to hire their first iOS dev, or to have an MVP of their app made
2) contact all of them (this is a numbers game) by pitching yourself and how you have the exact skill set they need, include a portfolio, and mention your terms up front (hours per week/desired rate/no I don't work for sweat equity)
Even people looking to hire full timers are probably desperate enough to consider taking on a part timer, even as a temporary stop gap.
I prefer angellist jobs section to traditional freelance sites because you can avoid race to bottom bidding and avoid much of the competition. There are a lot of open minded people looking for high quality workers out there and are thus willing to pay a better hourly rate, but they avoid most freelancing sites and focus on full time because they don't think there is an alternative- be that alternative to them
I have one of the latest generation of xps 15- looks and works great. I'm on the final beta of Ubuntu 16.04 using cinnamon 2.8, works perfectly out of the box with nvidias drivers (using nvidia-prime instead of bumblebee to control optimus since bumblebee wasn't cooperating for me this time around)
It doesn't seem like there is much you can do about it though. If you don't have enough resources to retain the good employees that you need, that's a valid issue to raise with the CEO. He can either get you those resources, or else there could be staffing problems. I don't think anyone joining as an early engineer expects to get more equity than a co-founder though. And you yourself said that people like him. So morale-wise, it's probably fine as long as he finds somewhere else in the company to contribute more.
From my limited perspective, it doesn't sound like it's your decision to make. If you've made your opinions clear to the CEO, that's great and you've already fulfilled your duty. Let the co-founders sort it out between them, it may take time to transition the lackluster technical co-founder into a new role. If business is going well, it's unlikely he would leave the company though given he is probably got a while left to vest. As long as he isn't hindering your work and creating infighting/tension in a power struggle, it doesn't sound like he's a problem.
Honestly, it sounds more like you're jealous of his compensation relative to yours. Has your compensation been adjusted since you started working there? If you're now doing the work of a co-founder, you should be compensated as such. If your role truly has escalated, they shouldn't take issue with you asking to have an adjustment made to your compensation in recognition of that.
I've actually been thinking about this a lot recently due to an SBK (motorcycle) race I went to last weekend. A freak collision lead to a pile up, ultimately 2 riders died after getting to the hospital and several others were injured. These things are rare, but they do still happen. Why should people be flying around the track at 100+ mph, risking their lives for our enjoyment?
Robotic sports could become big. But still, people identify with other people and we want to see something at stake. In e-sports you aren't physically at risk (aside from maybe your wrists), but your reputation certainly is. Colleges are fighting over football players far more than robotics competitors. Beyond financial or academic interest, I don't think competition of algorithms will ever hold peoples attention. The robots will still need human operators, because they are prone to error, which helps build the tension of watching live competition
While Bose is generally overpriced, these earbuds are the best I've found in the sub $100 range. The pair i bought has lasted 2 years despite my abusive use (shoving them in my pockets, tossing them around). And I like the sound almost as much as my overear Grados
And every cop has the right to punish you for it. Not a real legal right of course, but one forged through generations of corruption, insecurity, and abuse of power!
It's also a way to test new investment strategies as well. Basically, with what amounts to play money for them, they can test out new ways of evaluating teams and startups at an earlier phase and see what works and doesn't. They have a good idea how to evaluate companies that already have users and customers, but no idea when it comes to raw, unproven ideas. The value of that information when applied to their main batches could be pretty big... if it makes them catch one good startup they would have missed otherwise, it will have already proven a nice return.
I doubt many if any VCs see as many applicants as YC, and they're finding every way to leverage that data advantage they can against the competition
