While reviewing this Scrabble Tile Counter, I decided to give it a try myself. Here is the challenge, from Reddit's /r/dailyprogrammer:
Description
For this challenge we will be using the tile set from the English
edition, which has 100 tiles total. Here's a reference for the

You would like to set a password for an email account. However, there are two restrictions on the format of the password. It has to contain at least one uppercase character and it cannot contain any digits.
You are given a string S consisting of N alphanumerical characters. You would like to fin...

I want to check the truth of A + B - (A & B) == A | B for N-bit numbers. For example, here's a truth table for 2 bit numbers (I know I'm taking liberty with the concept of a "truth" table).
Here's the simple code I threw together in Python.
def check_truth(bits):
for x in range(2**bits...
I have a Cython function the takes a list of weights/probabilities (double) and returns a random index into the list.
For example
choose_one(np.array([0.1, 0.4, 0.2, 0.3]), 4)
Returns 0 with probability 0.1, 1 with probability 0.4 etc.
The Cython code is:
cdef extern from "stdlib.h":

So pretty much, a chat background is created and a text[0] is displayed with a button created under it.
The created button iterates thru text[] and finds the next one to display setting all others to inactive and the current one to active
text[] can hold a gameobject with just a text block, or up...
I have translated a project from Java to C#. I want to have a review of this project as some of the results are not as desired though the code is executing successfully.
How to share this project as it contains much code? Do I need to discuss each and every part of code or via what can I share...
I have created a pretty simple IOC container for C++ that should allow me to write less coupled code in the future and make my code easier to unit test.
Overall I am fairly happy however I feel like I could probably include some additional functionality to improve the code further.
Any suggesti...
A very simple question, but I haven't seen whether this is acceptable behaviour here. I do see mention of 'iterative' code reviews, which I assume refers to "post, receive answer(s), edit, answers updated" type questions.
Apologies if this is already explained somewhere.
Learning Go and trying to get a grip of the various concepts it uses. Following is my implementation of Quicksort (choosing last element as pivot). It takes the length of the array and subsequent array to be sorted as user input.

I have a code that converts each sheet of a spreadsheet into a txt file.
The code is working well, however given the big amount of exports (abuot 90 txt files) I'd like to seek advice on how to speed this code up.
This is my code:

So I am making post requests to a page for search queries. I am turning them into a session array so I can paginate the results. The process kind of feels ugly and long winded. I need code review for two things.

I am a newbie coder and I'm trying to learn good coding habits. I'm making a Simon Says game challenge from Free Code Camp in Angular JS. Working code is here: http://codepen.io/sharonghae/pen/dXOprE

While playing Mercy, I tend to always keep everyone healed as much as possible, and try to never let anyone die. This is mainly due to habits I have developed from playing healers in other games where dying is bad. However, Mercy's ultimate can revive them within 10 seconds, so when should I let ...
I recently got an email from a close friend of mine, that goes something like this:
We're looking to sell our rental house and buy a new one. We found one we like, but the housing market is very hot right now and it's not likely to be on the market for long. Unfortunately, the last tenants ...

Excellent points Alan. Appreciate your input and time. Will keep them in mind for future programming assignments.
I made some changes to my class structure and the way I determine a win. I was attempting to decide if it made sense to keep the player completely isolated to TicTacToe game class or if it made sense to make a player class to add additional functionality.
So that you can see the progress of t...
I thought I'd give a shot at creating my own version of dealing 5-card hands to n players in VBA, printing them to columns and coloring hearts and diamonds red.
I felt I might have been a little repetitive and I had to jump through some hoops to avoid ByRef. Anyhow, what can I improve?
Option E...I have to benchmark my code often, and decided that it is about time to implement an easy API for that:
current_time.h:

#include <cstdint>
class CurrentTime {
std::chrono::high_resolution_clock m_clock;
public:

The following is some JavaScript that I wrote to join two arrays of objects by an identifier. The goal is to extend the objects in a1 to include the extra fields in a2 and a3. What could I improve here?

const key = k...
I decided to make my own version of snprintf in C. I intentionally changed some things though. My version guarantees the buffer printed to will be null terminated, and it returns the amount of characters printed to the buffer, not the amount that would have been printed if the buffer's size was n...

I have a small shell script that uses sed to take an input file of URLs with hand-written notes around them and strips the notes and puts each URL on its own line. For example:
