> We don't have the capacity to support Cinder as an independent open-source project
Our team is smaller than you might think! You also left off the last half of that sentence, which is quite important: "nor any desire for it to become an alternative to CPython."
We'd love to see the ideas and implementations in Cinder end up in upstream CPython in some form or another. It'll make our lives easier in that we won't have to maintain as much forked code, and hopefully everyone else will benefit from a faster CPython.
We’ve chatted with kmod a few times and let him know we were open sourcing Cinder. Hopefully the projects can learn from each other. As _carljm mentioned, Pyston was restarted way after Cinder was in production and we had already implemented a significant amount of the core JIT functionality.
I participated in this study at Stanford for a while. The results are pretty dramatic. I doubled the number of pull ups that I could do in six weeks and went from being able to do 12 reps of 155 on bench to 12 reps of 175.
