  • Thanks! Both look like very decent studies so I am not certain where the difference comes from. I suspect that the division into age brackets, or averaging across all of the them may be the cause. Either way, it seems that the effects of being slightly overweight are barely statistically significant. The more you know

    What the hell is this? I am wondering if the people in this picture ever even met boys and men that wrote fan fiction, because it sure as hell never was cool. Writing in general in many genres like romance, poetry - and of course fan fiction - got young men I knew bullied. The girls I knew also were made of fun of for it, but typically less so. Except for creative writing being more normalized for women in the cultures I have experienced, I would argue this is a gender agnostic issue. The later posts get it, imo



  • Cool, didn’t think of that one. But it would still work, since you could consider that a constant in front of the f(x) not raised to the nth power (easier to imagine if we have a constant function, then its just (b-a)). The nth root will then normalise it to 1 for any real factor.

    I don’t know a single person who consumes milk because they think they require it. They just like the taste of dairy products.

    The subsidization is an issue imo, but I don’t think people are as brainwashed regarding milk as you assume.






  • Clearly you can address more bytes than your data bus width. But then why all the “hacks” on 32-bit architectures? Like the 36-bit address bus via memory mapping on SPARCv8 instead of using paired index registers ( or ARMv7 width LPAE). From a perfomance perspective using an address width that is not the native register width/ internal data bus width is an issue. For a significant subset of operations multiple instructions are required instead of one.

    Also is your comment about turing completeness to be taken seriously? We are talking about performance and practicality. Go ahead and crunch on some 64-bit floats using purely 8-bit arithmetic operations (or even using vector registers). Of course you can, but the point is that a suitable word size is more effective for certain computational tasks. For operations that are done frequently, they should ideally be done at native data-bus width. Vectored operations will also cost performance.


  • I am unsure about the historical reasons for moving from 32-bit to 64-bit, but wouldnt the address space be a significantly larger factor? Like you said, CPUs have had vectoring instructions for a long time, and we wouldn’t move to 128-bit architectures just to be able to compute with numbers of those size. Memory bandwidth is, also as you say, limited by the bus widths and not the processor architecture. IMO, the most important reason that we transitioned to 64-bit is primarily for the larger address address space without having to use stupidly complex memory mapping schemes. There are also some types of numbers like timestamps and counters that profit from 64-bit, but even here I am not sure if the conplex architecture would yield a net slowdown or speedup.

    To answer the original question: 128 bits would have no helpful benefit for the address space (already massive) and probably just slow everyday calculations down.




  • Yup, I know, it doesnt check out at all, you wouldn’t put a rotary on a helicoptor. But “rotary” engines were indeed used on aircraft, since they also refer to a radial cylinder configuration where the engine housing moves and the axis is fixed. So I think it’s likely they were referring to the common WWI plane engine. I didnt think of a wankel at all till you mentioned it! Interestingly enough, modern wankel engines are also sold for helicopters.
