编译：Python开发者 - Jake_on 英文：Quora http://python.jobbole.com/85986/ 有网友在 Quora 上提问，「你用 Python 写过最牛逼的程序/脚本是什么？」。本文摘编了 3 个国外程序员的多个小项目，含代码。 Manoj Memana Jayakumar, 3000+ 顶 更新：凭借这些脚本，我找到了工作！可看我在这个帖子中的回复，《Has anyone got a job through Quora? Or somehow made lots of money through Quora?》 1. 电影/电视剧 字幕一键下载器 我们经常会遇到这样的情景，就是打开字幕网站subscene 或者opensubtitles， 搜索电影或电视剧的名字，然后选择正确的抓取器，下载字幕文件，解压，剪切并粘贴到电影所在的文件夹，并且需把字幕文件重命名以匹配电影文件的名字。是不是觉得太无趣呢？对了，我之前写了一个脚本，用来下载正确的电影或电视剧字幕文件，并且存储到与电影文件所在位置。所有的操作步骤仅需一键就可以完成。懵逼了吗？ 请看这个 Youtube 视频：https://youtu.be/Q5YWEqgw9X8 源代码 存放在GitHub： subtitle-downloader 更新： 目前，该脚本支持多个字幕文件同时下载。步骤

Infinite Webpack watch loop - how to ignore changes to .js files, etc

由 ╄→гoц情女王★ 提交于 2021-02-09 11:09:08
问题 My webpack -w command using ts-loader is in an infinite loop. I am guessing it's because webpack -w is seeing changes to .js files, so that causes the loop : webpack -w => ts transpile => .js changes => webpack -w has anyone seen this before? Is the best thing to do to tell webpack -w to ignore .js files? How can I do that? Here is my webpack.config.js file: module.exports = { entry: ['babel-polyfill', './lib/index.ts'], output: { path: path.resolve(__dirname + '/dist'), filename: 'suman.js'

Multiple party peer.js application

由 一曲冷凌霜 提交于 2021-02-09 11:01:27
问题 I am brand new into PeerJs and WebRTC. I have got a 1:1 NodeJS/PeerJS application working in my remote server and that works great. However now I want to explore extending this to a 1:N model where a host ID can have multiple peers connecting to them and each of the peers can receive every other connected peer's audio/video. I am ok with about 4-5 parties in a call for now so a mesh architecture is fine. In the future I would progress into a Media server based architecture to get more
