I made this piece of code as first step for a bigger project to iterate and manage bookmarks: open, rename, place in new folder structure, or delete each one of them. This first step is a parser to get a useful json file with the structure and data of each bookmark and folder. I've usex regex instead of beautifulsoup t... | stackexchange/codereview |
I want to construct a form builder for an internal project in mvc4. I am using partial views to load the various controls. However I feel that having ten or 20 action-results in my HomeController would not be the best way to go.
So I am wondering how I could do the following more efficiently.
As you see here I have thr... | stackexchange/codereview |
Practicing Prototypal Code
I'm focusing on practicing a very prototypal structure with my code (non library oriented) to begin learning to reuse large portions of my application infrastructures where applicable in future projects. With this in mind, I don't have experience with prototypal programming before now, and wo... | stackexchange/codereview |
I am solving problem GRAVITY on SPOJ. Each test case is a rectangular ASCII grid of dimensions m × n, and you have to determine whether it is possible to find a path from the 'S' square to the 'T' square, moving using the space squares and avoiding '#' obstacles, in at most O steps (diagonal steps allowed).
I am using ... | stackexchange/codereview |
From a sorted vector of indices (toRemove), I would like to remove from another vector (v) the elements at these indices. Note that I need to preserve the order of the remaining elements in v. toRemove can be modified at will however.
An easy way to do it would be to start with the last element of toRemove and remove t... | stackexchange/codereview |
I am coding on codingame.com, where one of the 'easy' challenges is to assign MIME type strings to input strings of file names based on their extensions.
My code passes four out of five of the test cases, and the last one is an optimization test. A big data set is inputted, and my approach times out.
I started coding ... | stackexchange/codereview |
I've made a function to print all paths from root to all leaves in a binary search tree. I already have an insert function, which I haven't included in the code here as I felt it was irrelevant to the question. However, assume that it works. The code provided does produce the correct results. However, is it optimal? Is... | stackexchange/codereview |
I have been trying to find defects (brown/copper parts) on this sample using PyQt, OpenCV and Python:
And I can find defects, too. My problem is, I have nobody to ask, get feedback etc. I need some feedback about my code. Of course, I don't want someone to review my code line-by-line, but even a simple reviewing would... | stackexchange/codereview |
I would like to do the following:
I have a list data of 3-tuples that I need to go through, for each tuple base_tuple I want to know the index index_max of the maximum value held in base_tuple and replace base_tuple with a new 3-tuple new_tuple that only holds 0s except for the value at index index_max which is set at ... | stackexchange/codereview |
I have written code using Python for Fully Constrained Least Squares (FCLS) Linear Spectral Mixture Analysis, which could be applied for unmixing multispectral image successfully.
However, the operation efficiency is very low, taking about 2 hours for each MODIS image (rows: 1620, columns: 3024, bands：7, blocksize: 512... | stackexchange/codereview |
This is a very simple clone of Flappy Bird using Kivy, to be used for programming class for teens. The game consists of 3 classes: Bird, Game, and ResetBtn.
Q: How to make it more efficient, clean, and clear for the students? (without using kv file)
Code Explanation:
The Bird class inherits from Image class, a Clock... | stackexchange/codereview |
I've written a tiny function for asking questions intended for my POSIX shell scripts, where I often need user input.
The function takes 2+ arguments, where:

I also changed my style by a bit, no longer use ${var... | stackexchange/codereview |
I've been playing around with writing a simple static blog generator in Haskell (mostly for experience, since there's probably more than a few already made choices that fit my needs). I don't have very much experience with functional programming, but I've been doing a lot of C++ lately, so using typeclasses as "interfa... | stackexchange/codereview |
