This is a follow-up question for Calculate distances between two multi-dimensional arrays in Matlab. Given a set SX $$ S_{X} = \{ { X_{1}, X_{2}, X_{3}, \dots, X_{n} } \} $$ where n is the count of elements in set SX (the cardinality of set SX) There are $${{ n }\choose{2}}$$ element-wise distanc...

(Not too sure if this type of question is appropriate for this site. Feel free to vtc if it's not) This mmap usage tutorial that I found on linuxquestions.org has a subtle bug in it that other forum members apparently missed. Can you find it? #include <stdio.h> #include <stdlib.h> #include <sys/t...

I sent this text message via Python SMTP, and looks like some carriers break the messages into 2? How can I avoid this? I’m trying to send mass message to individual phones without having to pay for a number or service, just pure Python. I also don’t mind using my number, just don’t want to pay f...

I wrote the following Bash scripts to make pull-mode backups with restic, a backup solution written in Golang, similar to Borg Backup. The main use case for this script is pulling backups into a central backup server that you trust, especially if you don't want to create a shell account or sftp u...

An tiny UI library is being written for fun and since its C++ and not C, I attempted to do the "right thing" and use stack objects with move semantics rather then heap objects with new/delete. Starting here: control.AddChild(EditControl{{10, y += 30}, {200, 20}, TEXT("New Edit Control")}); This ...

I want to create ENUM which maps different statuses: public enum BusinessCustomersStatus { A("active"), O("onboarding"), NV("not_verified"), private String status; BusinessCustomersStatus(String status) { this.status = status; } public String get...

I recently came across the OneOf<T0,...,Tn> package from mcintyre321 via a video by Nick Chapsas, which presents the idea of holding exception types to be returned in the same object as would hold a successful result; e.g. public OneOf<User, InvalidEmail, EmailAlreadyExists> CreateUser { /* ... *...

Created a new typedef and making functions supporting it making it user-friendly [specifically programmer friendly] What does the code do? It makes users [programmers] easy to deal with strings as most functions are there. additionally, we can append, obtain substrings, replace string very very ...

So I implemented a program that takes an input file, two command strings and an output file to mimick the behaviour of running : <input cmd1 -option | cmd2 -option > output that's called like this : ./pipe input "cmd1 -opt" "cmd2 -opt" output and I did without using the wait system call since wh...

I am supposed to write code for an assignment. The goal is to make 2 threads (which are objects of a class that implements runnable) take turns printing the alphabet. One of them prints upper case while the other one prints lower case. (they print only a single letter each turn, not the whole alp...

I play a lot of old-school western CRPGs, and most of them (if not all) require the player to generate an avatar at the start of a new game, including naming the character (with names that will never be pronounced). I want my character to have the most unique and beautiful name, with as few names...

I have solved this problem from the CodeChef platform using the Python prorgamming language Here is the code: test_cases = int(input()) for _ in range(test_cases): n, d, h = [int(x) for x in input().split()] rain_amounts = [int(y) for y in input().split()] red_alert = False water_level...
