How to write a large buffer into a binary file in C++, fast?
...slow down (lower transfer rates) as they get older (because of non working bits).
I am seeing the code run in 63 secondds.
Thus a transfer rate of: 260M/s (my SSD look slightly faster than yours).
64 * 1024 * 1024 * 8 /*sizeof(unsigned long long) */ * 32 /*Chunks*/
= 16G
= 16G/63 = 260M/s
I get a...

How can I quantify difference between two images?
...ion and is much better than any pixel-wise comparison. If there's a little bit of noise in your webcam's image or if the image is shifted by even one pixel, then a direct comparison will pick up all these meaningless changes. A more robust approach would be to compute the discrete cosine transformat...
'float' vs. 'double' precision
... representation, not a decimal one.
Single precision (float) gives you 23 bits of significand, 8 bits of exponent, and 1 sign bit.
Double precision (double) gives you 52 bits of significand, 11 bits of exponent, and 1 sign bit.

Join vs. sub-query

Historically, explicit joins usually win, hence the established wisdom that joins are better, but optimisers are getting better all the time, and so I prefer to write queries first in a logically coherent way, and then restructure if performance constraints warr...
