C# Extension Methods which wrap Socket APM methods in awaitable TPL wrappers. All methods return Task<Result> or Task<Result<T>> objects, the code for the Result class is given as well.

Helpful C# Network/IP functions. Parse IPs from any arbitrary block of text, retrieve private/public IP addresses and check if IP exists in any range defined by an address in CIDR notation.

// async Main is a C# 7.1 feature, change your project settings to the

a-luna / ConsoleProgressBar.cs
Last active April 16, 2021 04:31 — forked from DanielSWolf/Program.cs
Progress bar for console applications, added the ability to customize the various components of the progress bar. Added the ability to display or hide the progress bar, percent complete and animation. And just for fun, I created a set of animation sequences which can be used instead of the default "|/-\-" progress indicator.
namespace AaronLuna.Common.Console
{
using System;
using System.Linq;
using System.Text;
using System.Threading;
public class ConsoleProgressBar : IDisposable, IProgress<double>
{
readonly TimeSpan _animationInterval = TimeSpan.FromSeconds(1.0 / 8);

Parse the text of a .env file to a dictionary of environment variables using only the Python standard library. IMUBVHCIO*, the list/dict comprehensions perfectly straddle the line between an elegant use of syntax and an infinitely dense mass of code (the dreaded "neutron star effect"). And extra bonus: Type hints!

Helpful Python datetime functions I've curated over time: timezone conversion, formatting aware/naive objects as strings, custom "timespan" namedtuple that provides more data than timedelta object, and more!
import time
from collections import namedtuple
from datetime import datetime, timedelta, timezone
from dateutil import tz
DT_AWARE = "%m/%d/%y %I:%M:%S %p %Z"
DT_NAIVE = "%m/%d/%y %I:%M:%S %p"
DATE_MONTH_NAME = "%b %d %Y"
DATE_ISO = "%Y-%m-%d"

Here are three Python decorators that I use quite often: add timeout functionality to potentially long-running functions, add retry-logic to unreliable functions, and measure the execution time of a function. Also, pytest functions are included as usage examples of each decorator.

import logging
from datetime import datetime

DT_NAIVE = "%Y-%m-%d %I:%M:%S %p"

Whenever I start a new project, I need to figure out exactly which packages are required for testing svelte components with jest. I am documenting the list of packages and required config files here to avoid repeating this in the future.
npm i -D @babel/core @babel/preset-env @babel/preset-typescript @testing-library/jest-dom @testing-library/svelte @types/jest @types/node @types/testing-library__jest-dom babel-jest jest svelte-jester ts-jest ts-node typescript
