Problem statement:
The following iterative sequence is defined for the set of positive integers:
n → n/2 (n is even)
n → 3n + 1 (n is odd)
Using the rule above and starting with 13, we generate the following sequence:
13 → 40 → 20 → 10 → 5 → 16 → 8 → 4 → 2 → 1
It can be seen that this sequenc...
Preamble
I want to be able to test methods which communicate over a simple exclusively asynchronous two-way stream-like interface which may underneath use any of a number of communication methods (e.g. sockets, named pipe. In order to test these, I need a memory-backed implementation, where I ca...
Working with PyTorch tensors, i need to do following operation:
def pairs_by_flags(self, x_batch, y_batch, max_flag):
#split x_batch on pairs
sizes = (x_batch.size(0)//2, *x_batch.size()[1:] )
items_pos = torch.zeros((max_flag,), dtype = torch.long, device = x_batch.device)

I am working my way through "Cracking the Coding Interview" and I came up the question(3.6) to design a data structure to manage an Animal shelter with 2 animals, Cats, and Dogs such that when we dequeue the oldest animal should be removed first (FIFO)
I implemented it as below. What all improve...
im trying to complete mips program code about a calculator program that can calculate integer addition / subtraction written using the MIPS assembler.

This is a simple boilerplate / template for a bigger program (i Hope), either linked to a DB or including a GUI frontend using PYQT or TKinter.
This is just a little tool I wrote to keep track of my own hours.

Here is my situation:

I'm using styled-components. Many of those Filter components are using the same styled-components to display. Like:...
I have a model called Document, in this I have a method that I use throughout my website to get the full path to the specific document:

I have a list of items i pull from SharePoint and want to filter them in my custom list view page. So my function works exactly how I want it but it seems messy and Im hoping someone could point me to or explain a better way of achieving this or an "optimized" version of what I did.

Here is the question from the book of Mark Newman
a) Read in the data and, using the trapezoidal rule, calculate from them the approximate distance traveled by the particle in the x direction as a function of time. See Section 2.4.3 on page 57 if you want a
reminder of how to read data from a fi...
This is my first large project, a Text based fighting simulator.
It is very clunky, do you have any ideas on how to make the code better?

I was wondering how acceptable or bad it is to declare a class within a function in python, that also takes care of a correct instantiation of this class.

class AuthTokenProvider:

Could someone please point out the noob error being made in the following code to read PDF from text? [Just in case, portable WinPython needs to be used on Windoze without local admin rights.]

I've been thinking about the AsyncLazy<T> class that Stephen Toub and Stephen Cleary present in various resources such as this. I am trying to find a way to integrate cancellation with AsyncLazy<T>. Microsoft has a version of AsyncLazy<T> in their Visual Studio 2019 SDK that offers a GetValueAs...
This is my third (and hopefully final) time re-writing this program. It was recommended I use Pathlib and it simplified my code, it's easier to read and understand than the first two monstrosities.
I also changed the way it functions, instead of the user providing a text file, the user creates ...

When working on a large codebase, I often need to switch between deeply nested directories quickly. To make my life easier, I came up with a bookmarking script.
