I have just started coding. Anything to help simply or improve the code?
This is fully finished and ready to play, though the ball bounces off the wall directly behind the paddle, rather than off the paddle itself.
Edit: After playing around with the game. One of my friends pointed out that whenever I scroll down on t... | stackexchange/codereview |
I've created some methods to help me convert PDF to text and then text to a JSON object. I've never done this before and I'm using this exercise as a way to improve my knowledge of Ruby.
The following code does what I want, it works. It just returns a very ugly object. Right now I'm trying to craft some regular expres... | stackexchange/codereview |
I'm working on a project (it's a language), and for that project, I decided to go with a low-level C++ style, so that means making my own data types. I recently got done making my own string class implementation. This is actually the first time I've made a string class before, so I may be doing a lot of things wrong. A... | stackexchange/codereview |
I'm starting to learn the object oriented aspect of PHP. In this regard I made a small "exercise" of sorts "translating" one of my PHP functions into OO mode of PHP. I'm asking if there are there any recommendations you can give me concerning my predicament.
Example of non-OO PHP:
<?php
function pristup($servername, $u... | stackexchange/codereview |
Here I am trying to avoid hardcoding in flash messages by using I18n. Also, I have tried to use a CSS selector for submitting the form to make the tests less brittle (I don't really care that much about what the text on the button is - more what happens when submitting).
Is this a good approach for making tests less br... | stackexchange/codereview |
In F# the Railway Oriented Programming pattern can be implemented synchronously using the Result<'t,'terr> type as result value for functions, so they can be foreward piped like:
let result =
func1
|> Result.bind func2
|> Result.bind func3
|> Result.bind func4
I would like to implement the same patter... | stackexchange/codereview |
I'd like to eliminate the code duplication in the following two methods by moving the common code into a separate method callable by both. The comments indicate the blocks of code that have a differing implementation in each method.
def compute_totals_h(self, size, bad_codes):
with open(self._in_file_path, self._FI... | stackexchange/codereview |
I am writing a Settlers of Catan server in Haskell for fun. Currently I am passing around state manually. I want to learn more about the State monad and want to incorporate it into my project.
However, my GameState has multiple data constructors that I pattern match on to yield different functionality. Three of such da... | stackexchange/codereview |
After understanding HashMaps, I decided to implement my own using 3 classes HashMap, LinkedList, and Node. I knew how to implement LinkedList from before.
Can you please give me feedback on this. Will this be an acceptable implementation for a technical interview?
Also do we actually need to implement the data structur... | stackexchange/codereview |
I made a program that lets the user input text into a text box.
The user can choose a number to rotate each alphabetical character by that number,
and the output box will diplay the converted text.
Here is how it runs:
Among the code is

# print('\n'.join([''... | stackexchange/codereview |
I am currently developing a puzzle game that has sequence numbers. The player has to fill the grid with sequence numbers in ascending order. Starting from 1 the player can move horizontally or across and can skip a square in between if it is empty or blocked.
To generate the puzzle automatically, my code is doing the f... | stackexchange/codereview |
I'm currently trying to improve my coding skills, so I'm trying to code a Tic Tac Toe game. At one point a "win check" is needed.I'm using this code to check:
public void CheckWin(States state)
{
if(fieldA1.GetState == state && fieldA2.GetState == state && fieldA3.GetState == state)

The problem that this is based on is something like the following:
