One area that bothers me is using members of System.String. These often need to be chained together, but the only way to do so that I've seen so far is pretty much the same as C#.
For example, I've written a function to generate the pretty bit at ... | stackexchange/codereview |
I am using knockout in my project. I have some models like EmployeeModel, ServiceModel etc which user can update. On UI I give the user a Cancel control button by which he can revert the changes. On cancel I have to revert the model change back to its original state. For this I found these two good approaches by @rniem... | stackexchange/codereview |
I am wanting to implement an AlertDialog with a list into my app and I created a sample to see if I can get the result that I am looking for. It seems I do have the result I wanted but before I implement it into my actual app, is there a way to make my code better?:

<?xml version="1.0" encoding="utf-... | stackexchange/codereview |
As a side toy project for my Genetic Algorithm, I decided to try to create a macro that lets you use maximize: ... subject to: ... linear problem notation to generate fitness functions. Those fitness functions can then be used in a genetic algorithm to solve linear problems through brute force.
Yes, I'm aware genetic a... | stackexchange/codereview |
For the implementation of the Playfair encryption I needed a custom struct called Cell. This is because I not only need an array of characters I also want to get Elements in a matrix based on their "cartesian" position.
public struct Cell
{
public char character;
public int X;
public int Y;... | stackexchange/codereview |
This is my first program with C# and VS and was originally a VBA Add-In I wrote. I have embarked on this as a learning exercise. The code does work and provides the desired output in a new workbook.
The code below is called from a button on a custom ribbon created in Excel. It collects data from other workbooks w/o ope... | stackexchange/codereview |
I have two variables that could be the same. In such a case I am assigning one of them to be undefined. Is this code the best way I can write it?
let folderOwner = $("#change-folder-owner").val();
let folderUser = $("#user_name_alias").data('value');
folderOwner = (folderOwner === folderUser) ? undefined :... | stackexchange/codereview |
I am having a trouble speeding up my implementation. The question is, given a range of numbers from long a to long b, find how many lucky numbers are between a and b inclusive. A number is a lucky number if it contains either 1 or 3. If it contains both 1 and 3, it is not a lucky number.
Currently, I am iterating over ... | stackexchange/codereview |
Not sure how subjective this question is however I am looking for a peer review and general feedback on the intuitiveness and scaffolding potential of a framework concept. I have a gist on GitHub here: node.js MVVM framework concept
Is this more or less intuitive then using pseudo code and a template engine, such as ha... | stackexchange/codereview |
My model is based on the Ultimatum Game. I won't go into the intuition behind it but generally speaking it functions as follows:
The game consists of a n × n lattice on which an agent is placed at each node.
During each time step, each player on each node plays against a random neighbour by playing a particular strate... | stackexchange/codereview |
I would value your opinion on the following piece of code. I am rather new to both Python and Monte Carlo analysis, so I was wondering whether the routine makes sense to more experienced and knowledgeable users.

Here the task (in Indonesian).
I think my binary search algorithm is correct.

I keep seeing /subsite/../global/css/file.css when I look at my website's source code, and today I decided that I want to get rid of the unnecessary traversal in the path itself, so it becomes /global/css/file.css. I made myself a function which I now use for all paths. Here is the base of my function that accomplishes... | stackexchange/codereview |
