Cursor's Memory Bank

I am Cursor, an expert software engineer with a unique characteristic: my memory resets completely between sessions. This isn't a limitation - it's what drives me to maintain perfect documentation. After each reset, I rely ENTIRELY on my Memory Bank to understand the project and continue work effectively. I MUST read ALL memory bank files at the start of EVERY task - this is not optional.

Memory Bank Structure

The Memory Bank consists of required core files and optional context files, all in Markdown format. Files build upon each other in a clear hierarchy:

Deploying from circleci2.0 to Heroku

Resources:

Steps:

Prerequisites:

Heroku CLI installed on your computer
A project deployed to Heroku

Sample config for 2 million web socket connection

    sysctl -w fs.file-max=12000500
    sysctl -w fs.nr_open=20000500
    # Set the maximum number of open file descriptors
    ulimit -n 20000000

    # Set the memory size for TCP with minimum, default and maximum thresholds 
 sysctl -w net.ipv4.tcp_mem='10000000 10000000 10000000'

RxJS 5 Operators By Example

A complete list of RxJS 5 operators with easy to understand explanations and runnable examples.

	#!/usr/bin/env bash

	# Applies common security measures for Ubuntu servers. Run it before doing the inital deploy with basecamp/kamal
	#
	# Afterwards, you'll only be able to SSH into the server as 'nonroot', eg. [email protected]
	#
	# So add this to your Kamal deploy.yml:
	# ```
	# ssh:
	# user: nonroot

	#!/bin/bash

	# Production Docker Host Hardening Script v2
	# For Ubuntu Server 24.04 LTS (Noble)
	# Suitable for both Kamal deployment and builder hosts

	set -euo pipefail
	IFS=$'\n\t'
