[1:14:42][@ffsjs][From a beginner's perspective, it seems that in software rendering, keeping "milliseconds per frame" in a certain controlled boundary is somewhat in the programmer's control (depending on the code quality and orientation towards performance). Does that become more difficult when going into hardware rendering (with drivers) territory? Or is it the other way around?]
[1:15:26][@dudeinbasement1][Are we going to do any compression on the image, or only movement of the torso?]
[1:15:45][@ffsjs][Which game design decision requires hopping / tilejumps as opposed to the previous way of moving the hero?]
[1:16:04][@ttbjm][Is it possible to create animations like Looney Tunes where looking at still frames you could see multiple heads and limbs or features that are extremely exaggerated and distorted? Somehow it still looks fine in motion. Smear animation is a term I could find in 30 seconds of googling]
[1:17:27][@yolosswagez][Why not use java instead of C?]
[1:20:22][@yolosswagez][Jmonkey and LWJGL are professional open source libraries that are written in java, just to name a couple]

[1:27:03][@cubercaleb][What do you have to say about the researchers that claim that java can be faster than C++ at times?]
[1:28:33][@sssmcgrath][It's pretty great. Also, re: metaprogramming, did you see Per Vognsen's btree metaprogramming thingy? Apparently it copies Jeff Roberts' AVL-tree configurability scheme]

Cinera 0.7.0 Update Add output parameter to all of hero/code, hero/intro-to-c and hero/misc, preserving the current URLs while allowing different .hmml filenames, notably for hero/misc which now gets sorted chronologically.
