Why I Write This?

Some day, I was building plyvel in macOS(Apple Silicon). plyvel is the interface to LevelDB and build a Python Extension for using the leveldb C++ library. In that building process, I found:

❯ python setup.py build_ext -i -n
running build_ext
skipping 'src/plyvel/_plyvel.cpp' Cython extension (up-to-date)
building 'plyvel._plyvel' extension
creating build

Python Build Tools

In modern Python package project, it often includes such files:

pyproject.toml
setup.cfg
setup.py
MANIFEST.in

What's the relations among them and the purpose from them?

npm and yarn mirror

mirror priority:

Project .npmrc > Global .npmrc > Default mirror source Project .yarnrc > Global .yarnrc > Default mirror source

npm mirror

Restore to default repository

Network Diagnosis

understand routing table entry

An explanation on the USB virtual ethernet

Knowing simultaneously these three things for failing and working circumstances would be quite useful.

1: Intro

Welcome to the interactive tutorial on how to use side-effect "operators" in MobX! Over the course of the next three samples, you'll learn (and be able to explore) exactly how autorun, when and reaction work, and when/why you would use them when building reactive applications.

	So you've cloned somebody's repo from github, but now you want to fork it and contribute back. Never fear!

	Technically, when you fork "origin" should be your fork and "upstream" should be the project you forked; however, if you're willing to break this convention then it's easy.

	* Off the top of my head *

	1. Fork their repo on Github
	2. In your local, add a new remote to your fork; then fetch it, and push your changes up to it

	git remote add my-fork [email protected]

	#!/usr/bin/env awk -f
	# Get the Min, Max, Median, and Mean of a Dataset
	NR==1 { max=$1; min=$1 }
	{
	sum += $1
	sumsq += ($1)^2
	$1 < min ? min = $1 : 0
	$1 > max ? max = $1 : 0
	}
	END {
