   Experience (with this style of development) helps out here. For stuff you're completely clueless on though, it still happens. And that's when you revise your design. Its far better to go in this direction than the other, in terms

   For games its mostly binaries (textures, models, sounds, etc). Dunno about anything else, but 100MB is not a lot of asset space these days, and 30MB is approaching game jam sizes.

   This is somewhat true, but you structure the code in a way so that rewriting any one part is easy. You keep your modules fairly large, your abstractions thin, and the code very literal. It's much easier to do a total rewrite on code th

   Not really. It boils down way closer to procedural than anything else. The three links he has at the bottom are very relevant.

   Honestly the non-intrinsic SIMD code is a mixed bag. I like the portability compared to intrinsics, but it encourages SIMD antipatterns like using a vector register to store one object (as opposed to using it to step over loops 4/8&#x2

   I'm not saying they wouldn't be nice, but they would certainly encourage SIMD antipatterns.

   Small nit: Data oriented != data driven (Jon Blow was talking about the former). There are some nice posts about using Data Oriented Design in Lua on the bitsquid blog, and I have used it once or twice in JS using Typed Arrays (It's aw

   I remember reading that it usually only takes a few days (like, one or two) of no caffeine in order to reset your body's tolerance to this. Not sure if it's accurate or not, but it sounds plausible to me.

   I can imagine this being more helpful if you lacked access to a debugger, and lacked the time (or desire) to build debugging tools by other means... Which I imagine is plausible in that context.

    Not the person you were replying to, but no. Basically, instead of trying to gain a bit performance out of one [x, y, z, w], you group your data so you have to process all of them at once, and then you load them as [x0, x1, x2, x3], [y0, y1

    This library doesn't seem to be focused on matrix math for computer graphics. FWIW, you don't tend to see a significant gain from writing those individual types as SIMD. The gain is from operations over large arrays of numbers. E.

    I imagine C++ doesn't allow FAMs because it wouldn't know how to call the destructors/constructors on the members of the array (or how many to call).

    As someone who uses the Unity WebGL export in production, it's a long way away from the point where you can simply build a game in Unity, deploy with WebGL, and expect it to work reliably. It took us several months of optimizations, re

    It's fairly disingenuous to say that implementing polygon-based (the article calls it "vectorial") collision detection on platforms is "very difficult to implement properly" without a physics engine. The collision d

    I've kept a list of 'touching' entities (and where they are touching) on each entity before. Every frame this was cleared and rebuild as collision detection is performed. The moving platform's update code will then move

    It isn't broken on touchpad for me. That said, if I'm being honest, it's fairly unpleasant to use on a desktop with a mouse. It scrolls you to the top after it loads (which is after the rest of the page), and behaves differen

    A physics system good enough to support this is probably ~200loc. Probably less if you cut out everything extraneous. All it is is AABB collision detection+resolution, and then some update code. I think the graph + graph algos would be tric

    This is awful. Some reasons, in no particular order - Straight up, this isn't data oriented. You're dealing with one object at a time. - This code is vastly harder to understand in its entirety, much less extend, than the data ori

    Worth noting that only the first two points there are relevant here, since these are not single file libraries. Also, the STB libraries work massively differently from C++ header only libs (#define STB_FOO_IMPLEMENTATION, for example). Also

    Lua has goto (and JS does not), which means not all cfg's are well structured. That could impact the compiler in certain ways. Lua also has finalizers, which effect the GC's design. The Lua/C api also makes it impossible for

    It would likely be less effort to port those parts to Lua instead of the whole system to node. Does D3 even run headless anyway?

    This is largely a tradeoff between framerate and visual effects. Current generation consoles can make 60fps, but not with the level of visual effects that are expected from them. Whether or not this tradeoff is worthwhile is at least partia

    There's a post by Mike Pall, author of LuaJIT, which explains why writing C is very suboptimal for maximally performant VMs: http://article.gmane.org/gmane.comp.lang.lua.general/75426 Worth noting that IIRC, for a
