I was wondering if I could get some input on how to make my code more concise, since I think in particular with the force simulation sections I have some repetition. And any other input to make my code more readable would be great. I have a mixing of jQuery and D3 but that is just a quick demo fo...
I've worked in Python in the past, but it's admittedly been quite awhile, so I'm a little rusty.
The basic idea of this assignment is to compute the sample mean and variance with a simple online algorithm using the following formula for the mean:
$$\bar{x_n} = \bar{x_{n-1}} + \frac{x_n - \bar{x...
I need to create a GUI using WxPython in the form of a Speedometer to display 9 different data values fetched from Adafruit IO. My code is shown below:

I'm trying to improve my code and algorithm to find out the longest word from a dictionary occurring as the sub-sequence in the given string.
Example : For example, given the input of S = "abppplee" and D = {"able", "ale", "apple", "bale", "kangaroo"} the correct output would be "apple".

I have the following Repository wrote in C#, I am using NetCore 2.2 and EF Core.
I was thinking how to write properly the Search method according to the SOLID principles.
This code gives a null reference exception when "Title" or "Genre" property is null. It means I will need to put an if to ch...
In several places I need to compute the next value, given a N:
double size = 1.0 / Math.Pow(2, N);
Since I won't be computing this value for N > 15 I have thought of the following performance optimization:
public static readonly double[] RegionSizes =
{
1, 0.5, 0.25, 0.125, 0.0625, 0....
I would like to get you opinion on this class, which is used to send http request (at that moment only POST method ).
It is working ok, but I would like to get response on : maintainability, reusability, security, code formatting, etc...

I have the Repository below, but I have noticed that there is a recurrent pattern try / catch which does not seem to be that clean, is there a better way to achieve or to extract that sort logic elsewhere?

Here is my code:

Updated Code
The original question can be seen here: Stack implementation in C++ using linked list
Changes (with the help of Martin):
Added copy constructor and assignment operator overload
Changed return type of peek() to const T& rather than T (this prevents unnecessary copying of data)
Cha...

I am experimenting with Javascrip ES6 import and export and wanted to achieve the following :
Use the import / export style of including Javascript files.
Import a class file and create an instance
Import a class file that extends another cla...
I'm creating a filter in python/django. I want to make a datetime human-readable.
You have multiple options:
Plain Datetime ("04. Februar 2018, 18:18")
(bools="False,False"),
sentence Datetime ("am 04. Februar 2018 um 18:18")
(bools="True,False"),
onlydate Datetime ("04. Februar 2018")

I have read a few sites on how to handle exceptions and I think I understand it better. Here is how I plan to handle it going forward. I used a lot of the guidelines here, https://isocpp.org/wiki/faq/exceptions.
Is this a sensible to handle it with c++14 as I'm using visual studio 2015. Would i...
Consider this example:
public int numberValue(String str){
return Integer.parseInt(str);
}
When giving a word that does not represent a number, we'll get back an exception of type NumberFormatException. How can I rewrite this short fragment to make sure that in this case, I'll get 0 back?
New to the C language. Which design mistakes have I made in my first C program? Or what can I improve? Any little detail is appreciated.
char str[100];
fgets(str, 100, stdin);
int len = strlen(str);
int len2 = len - 1;
int count = 0;
//loop through string

A Unit is composed of competences. A unit must have at least one competence and its name must not be in blank.
A Competence must have a descriptor, at least on...
