Coding Prompt - Reward system self scoring

	All code you write MUST be fully optimized.“Fully optimized” includes:

	• Maximizing algorithmic big-O efficiency for memory and runtime (e.g., preferring O(n) over O(n²) where possible, minimizing memory allocations).
	• Using parallelization and vectorization where appropriate (e.g., leveraging multi-threading, GPU acceleration, or SIMD instructions when the problem scale and hardware context justify it).
	• Following proper style conventions for the code language (e.g., adhering to PEP 8 for Python, camelCase or snake_case as per language norms, maximizing code reuse (DRY)).
	• No extra code beyond what is absolutely necessary to solve the problem the user provides (i.e., no technical debt, no speculative features, no unused variables or functions).
	• Ensuring readability and maintainability without sacrificing performance (e.g., using meaningful variable/function names, adding concise comments only where intent isn’t obvious from the code).
	• Prioritizing language-specific best practices and idiomatic

pourdaavar / retryDynamicImport.ts

Created October 13, 2024 13:02 — forked from mberneti/retryDynamicImport.ts

This utility function retryDynamicImport enhances React’s lazy loading mechanism by adding retry logic with a versioned query parameter. It retries importing a component multiple times in case of failure, which can be useful for bypassing browser cache or dealing with intermittent network issues. It can be used as a drop-in replacement for React…

	// Usage:
	// Replace React.lazy(() => import('x'));
	// with retryDynamicImport(() => import('x'));

	import { ComponentType, lazy } from 'react';

	const MAX_RETRY_COUNT = 15;
	const RETRY_DELAY_MS = 500;

	// Regex to extract the module URL from the import statement

pourdaavar / Virtual IP Address Failover Using Keepalived.guide

Created July 19, 2024 19:33 — forked from loinguyenduc101/Virtual IP Address Failover Using Keepalived.guide

Configuring Simple Virtual IP Address Failover Using Keepalived

	#### https://docs.oracle.com/cd/E37670_01/E41138/html/section_uxg_lzh_nr.html
	Enable IP forwarding:
	# echo "net.ipv4.ip_forward = 1" >> /etc/sysctl.conf
	# sysctl -p
	net.ipv4.ip_forward = 1

	Add firewall rules to allow VRRP communication using the multicast IP address 224.0.0.18 and the VRRP protocol (112) on each network interface that Keepalived will control, for example:
	# iptables -I INPUT -i eth0 -d 224.0.0.0/8 -p vrrp -j ACCEPT
	# iptables -I OUTPUT -o eth0 -d 224.0.0.0/8 -p vrrp -j ACCEPT
	# service iptables save
