UUID (Universally Unique Identifier)_ and CUID (Collision-resistant Unique Identifier) are both methods for generating unique identifiers, but they differ in their design and intended use cases.

UUID:
Definition:
A 128-bit number used to uniquely identify information in computer systems.

Characteristics:

When using clusters in Node.js, it's important to understand how clustering works and whether or not a load balancer is necessary. Clustering allows you to create multiple server instances that share the same port, which can be beneficial for utilizing multi-core systems. However, this does not inherently provide any load balancing capabilities on its own.

When you use cluster module in Node.js, it forks several child processes to handle incoming connections. Each fork listens on the same port and can receive requests for different parts of your application. Here's a basic example:

const cluster = require('cluster');
const http = require('http');
const numCPUs = require('os').cpus().length;

Here are several approaches to restrict API access to our frontend:

import cors from '@fastify/cors';

fastify.register(cors, {

Possible structures:

Task: We have an array sorted in ascending order:

a = [ 3, 4, 6, 9, 10, 12, 14, 15, 17, 19, 21 ]; Define a function f(a, x) that would return x, the nearest smallest number, or -1 on error.

Example:

console.log '1' after 1 second,
'2' after 2 seconds and
'3' after 3 seconds after start of the program.

The delay parameter only guarantees that your callback will not execute before that time has elapsed. Other queued tasks or operations could delay it further than the specified time.

const startTime = process.hrtime();

We use mongo:4.4.6 because of Error: MongoDB 5.0+ requires a CPU with AVX support. Container failed to start Solution from here: https://stackoverflow.com/questions/70818543/mongo-db-deployment-not-working-in-kubernetes-because-processor-doesnt-have-avx You may be can use mongo:latest

docker-compose.yml

version: "3.8"

const url = URL.createObjectURL(new Blob());
const UUID = url.substring(url.lastIndexOf('/') + 1);
