I'm not really super experienced async/await and working with tasks, so I thought I'd ask for some other opinions.
I'm working with code written by someone else that establishes a TCP connection. It works most of the time. But sometimes it just doesn't, and the connection gets dropped and we don...
I wrote this Python script as a utility script for me. It's something that could be achieved in a simple shell script or alias, but it wasn't 'verbose' enough for me in that format, or customizable.
This script, basically, is just designed to take and process whether a specified DNS TSIG keyfil...
So the problem I want to solve is very simple:
Given a string s and a string t, check if s is subsequence of t. there is only lower case English letters in both s and t. t is potentially a very long (length ~= 500,000) string, and s is a short string (<=100).
Example 1:
s = "abc", t = ...

So, I have spent the day working on this "tiny" library for JavaScript. The concept is pretty simple, applies simple pre-processing directives on the client side in order to help with creating the right code for that browser.
Question
What I am interested in obtaining from asking this ...
Args is an array, and can have any integer amount (0, up until whatever the limit is).. is there a cleaner way to check this?

I'm new to Observables. I'm using them to check if the user is logged in or not in the constructor of my root page.
I have nested many Observables in order to do this, and they are working fine, but I think that there is a way to flatten all of these nested Observables.
I just want you to revie...x^4 + 2x^3y + 3x^2y^2 + 4xy^3 + 5y^4 -->> Polynomial P

Recently while practicing I came across this problem , here is an excerpt from it,
A permutation of the numbers 1, ..., N is a rearrangment of these

I've implemented the prim algorithm to find the minimum-spanning tree of a graph represented as an adjacency matrix, but I'm not sure it's correct.

I've been messing with hashes in Java recently and thought of this simple sorting algorithm.
CONS:
Can only sort positive numbers and only integers
You must know the maximum size of integers that need to be sorted
PROS:

I've written a program that runs through a matrix of numbers, ranging from 0 to 2, and stores the results in a 2D vector.
I'm using the values in the 2D vector as the profile for a tile map for a game engine.
I want this to be optimal, and as this is my first attempt at it, I doubt that it is ...Based on responses to my question posted here, I've built a full implementation of a Location object. Such an object can be used to build a map for a text-based adventure game.
Feel free to review the code, leave some comments about the good and the bad of what you see.
