Please tell me if I'm doing this right, and what else is needed to make this hardened.
It seems like it's too simple, like there's almost nothing I'm actually doing. For example, there are 4 or 5 stacked using statements!
Here is the code to review:
class Program
{
static void Main(string...
In these link and link the Welford's algorithm was suggested to calculate variance.
I implemented in the template but it does not work:
template<typename T>
inline T varFast(const std::vector<T> vec)
{
double mean = 0, M2 = 0;
T variance = 0;
size_t n = vec.size();
for (size_t i...

I want to refactor code, so that it would be generic.

For an embedded project I want to shift a (byte) array left by a certain amount of bits. I've built this template function to do so:

const size_t chunks = bits / (8 ...
In my little project game, I have the following piece of code, in the static class DamageHelper, that takes a Spell, and returns it's damage in the Entity:

I'm currently writing a .NET Standard library presented via a fluent interface. It deals with objects and/or with collection objects and their items. The actual objective for the library is irrelevant.
So you might have something like:

the idea is to write a reusable grid component for my Vue2 pet project. As long as I want it to be reusable, it should not contain any data-specified logic (I guess). So I decided to store all render functions and event handlers in parent component and pass them to grid.
That's how it looks:

I am using requests and beautifulsoup to scrape 20000 urls, each web page containing a table of information. Essentially each web page is a like a combo, and it has several items, each item having a description. I am scraping two elements - item, description from each row in the table for all the...
I have come up with this structure to handle API calls using Alamofire + Gloss.
What do you think about it? Any thoughts or suggestions are welcomed, like performance, readability, names etc.
The multipart method I came up with was kinda in a hurry, it works but I think it could be much better ...
I have a situation where I have to use protocol to be conformed by NSManagedObject which has relationships with other entities.
My protocol is like:

class AccountMO: NSManagedObject {...
Some utility functions I re-wrote today:
Purpose:
Given an arbitrary list of 1-D arrays (possibly empty variables), return a
1-D array containing unique values from all lists.
Ex: Given (1,2,3) (1,2,4), (4,7,9) and Empty, return (1,2,3,4,7,9)
The returned list will not necessarily b...
Is the implementation clean enough & can be used in production?
I tried to write clean & bug-free code. It looks good to me.
I would appreciate any improvement suggestions.
One question I have is, what are the corner cases one might need to consider while implementing a Queue like this that mi...

I have some code that asks for a user input, and then uses TTS to convert that into speech and play the file. It then asks the user whether they want to repeat it and convert another input into speech, or whether they want to exit the program. Are there any improvements that I could make to the c...

You can store a list of friendships using two arrays (a max of 100 friendships).
