Tying in to all of the above is one of the most pressing concerns about the site I had in my own review, which is the gigantic pool of unanswered questions. There are, ...
You can use the LockBits method and pointers to access the image data directly.
Example for 24 bpp images:
bool equals = true;
Rectangle rect = new Rectangle(0, 0, bmp1.Width, bmp1.Height);
BitmapData bmpData1 = bmp1.LockBits(rect, ImageLockMode.ReadOnly, bmp1.PixelFormat);
BitmapData bmpData2 ...
I need to write a bit of code that will get a list of the rgb colours in an image and then translate them into a numpy array of lab colours. I have managed to do this but I would like to learn how I can do it more efficiently.
from skimage.color import rgb2lab
from skimage.io import imread

Don't Repeat Yourself as a principle doesn't really mean that you NEVER should repeat yourself. It's a general advice to avoid repetition.
First of all, I'd suggest not using single letters for things like small or large. Writing box--large is better. In this case, the letters are quite obvious,...
It feels like you are combining lots of hashing and string transformation in hopes that complexity will make your scheme more secure. That's not engineering or computer science, though — it's Cargo Cult Programming.
There are two ways that an API key scheme could work:
To generate the API key...
This is how I handle this situation right now:
For example, I have service that returns UserDto by user ID: GetUserById.
Service never return null or throw exceptions.
Service always return DTO objects derived from base class (DtoBase)
Each DTO object relates to some Entity type. Each entity h...
For testing algorithms such as these, it's good to provide your main() to show how you're doing your testing. Although the code there may already work, you cannot always determine how well an algorithm works if there is no test code.
Instead of creating a new Pair structure, consider using std:...

I wanted to try out writing an minimalistic connection pool implementation (out of curiosity and for learning). Could you all please review the code and provide feedback?
There are two classes (class names are hyperlinked to code):

I have wrote kNN (k-nearest neighbors) code as follows, but it is very slow. I want to get an exact k-nearest-neighbor, not the approximate ones, so I didn't use the FLANN or ANN libraries. Could you give me some advice on speeding up this code?
struct Pair{
int id;
double value;

#define MAX_STR_LEN 256
#define MAX_BOOKS 10
#define DATE_LEN 8
How do you choose these numbers? Does you code ensure that data in the file doesn't exceed these numbers?
In fact your readBookFile function has a bug: if the title of a book is nearly MAX_STR_LEN then the length of the whole file...
