Getting a slice of keys from a map
... not much more work, and in my tests (using a map with 1,000,000 random int64 keys and then generating the array of keys ten times with each method), it was about 20% faster to assign members of the array directly than to use append.
Although setting the capacity eliminates reallocations, append st...
In-place type conversion of a NumPy array
...(10, dtype='float32'); b = a[::-1]; c = np.vstack((a,b)); d = c.view('float64') This code takes 10 + 10 float32 and results in 10, rather than 20 float64

Difference between encoding and encryption
... to be transmitted safely, so it may be necessary to encode data using base64 (uses only letters, numbers and two safe characters).
When encoding or decoding, the emphasis is placed on everyone having the same algorithm, and that algorithm is usually well-documented, widely distributed and fairly e...
Why isn't the size of an array parameter the same as within main?
...func, it will immediately decay into a pointer to its first element. (On a 64-bit system, a 64-bit pointer is twice as large as a 32-bit int, so your sizeof ratio returns 2.)
The only purpose of this rule is to maintain backwards compatibility with historical compilers that did not support passing ...

...stead, I store a heavily quantized color (the palette has only 4 * 4 * 4 = 64 colors) that simply gets blended in in some proportion. Mathematically, this is equivalent to a variable brightness and constant contrast adjustment for each color. Unfortunately, it also means there's no negative contra...
