Yesterday I hacked up a simple component selection program. An example is shown at the bottom for the application, though this can be used generally for a lot of different simple circuits I come across.
It requires Python 3; I've only tested it on 3.8.

I am quite new to the MVC concept. I already know how to programme object-orientated from other languages like C++ or Java. I have implemented a little login system for test purpose.
I am not sure if my implementation is the correct way to do it with MVC. Any feedback is welcome.

I have written a SQL server stored procedure to generate "log" tables which store the old values of rows when a table is updated, and also record when rows are deleted ( and by who ). It's quite straight-forward, the log table has identical rows to the table being logged, plus a "Changed" column ...
Project Overview:
See how many times numbers would repeat x times on a digital clock output. This particular code only counts from 12:00 to 11:59, so it's technically only half of a day, I could take the (output x 2) for a full day.
Functions:
input_io():
Input the number of times you would li...
I have 2 variations of components that I wanted to create in React. They both use Radio buttons with the only difference is one adds an image to one side of it.

I have a typeahead widget to get the state or city's population according to what the user types

Design
A template class that will create a concrete instance of an interface class when given the name (as a string) of the concrete class.
This design is often seen in code, so the purpose of this class is to reduce the boilerplate code needed to write a factory class.
The template class wil...

I'm trying to take advantage of NumPy broadcasting and backend array computations to significantly speed up this function. Unfortunately, it doesn't scale so well so I'm hoping to greatly improve the performance of this. Right now the code isn't properly utilizing broadcasting for the computati...
I quite like purrr::partial(), which allows us to easily create partial functions. However, the partial function loses its remaining arguments from its signature (replaced with ...):
f <- function(x, y) {
print(x)
print(y)

}
ff <- purrr::partial(f, y = 1)
