    You say "we need to protect minorities and women from the white male oppressors" is not an accurate representation of their viewpoint. Then you proceed to say that minorities and w…

    You do realize that is exactly why alt-righters believe there is bias against white people? "We need to protect minorities and women from the white male oppressors" is basically th…

    In section 3.1 they say it is a performance issue.

    16 Psyche is far to big to move anywhere. 16 Psyche's mass is 2.27·10^19 kg and its orbital speed is 17.34 km/s. Earth's orbital speed is 29.78 km/s. So a perfect orbital transfer …

    The title is somewhat misleading. The suburbs are not dying; in fact they are growing [1][2][3][4] and this article makes no claim to the contrary. The article is saying that subur…

    Though for the purposes of comparisons, -0 and +0 are the same in IEEE 754. So the expression "x >= 0.0f && x <= 1.0f" is true for x = -0.

    SSE1 is single-precision only. SSE2 added double precision. So the bug will still appear for 'double' using just SSE1.

    Comment #13739721

    The solution is to compile with SSE2 on x86. (flags: -mfpmath=sse -msse -msse2) On x86-64, the compiler should default to SSE2. SSE2 is ~16 years old so compatibility shouldn't be …

    It works for 32-bit unsigned integers and double precision floats. For n Since there are only 2^32 values for 32-bit integers, it is possible to test all values in under a minute: …

    It does work, though not as well as using an integer multiply. The approximate latencies for Skylake are: div --> 26 cycles cvtsi2sd + mulsd + cvttsd2siq --> 6 + 4 + 6 = 16 cycles …

    Is there a good-faith way to ask that question? I'm legitimately curious if KirinDave has evidence that r/t_d buys upvotes.

    I'm not seeing that? In ARRAY_PUSH_BACK, it just inserts the element directly into the buffer, provided there is enough capacity. There is no separate allocation for an element. Yo…

    kzrdude is referring to the allocation of the Array struct on the heap. It should be something like this instead: Array array_create(size_t size, size_t sizeof_data) { Array result…
