What is Snowpack?

Snowpack is a modern, lightweight toolchain for web application development. Traditional dev bundlers like webpack or Parcel need to rebuild & rebundle entire chunks of your application every time you save a single file. This introduces lag between changing a file and seeing those changes reflected in the browser, sometimes as slow as several seconds.

Snowpack solves this problem by serving your application unbundled in development. Any time you change a file, Snowpack never rebuilds more than a single file. There's no bundling to speak of, just a few milliseconds of single-file rebuilding and then an instant update in the browser via HMR. We call this new approach O(1) Build Tooling. You can read more about it in our Snowpack 2.0 Release Post.

When you're ready to deploy your web application to users, you can add back a traditional bundler like Webpack or Parcel. With Snowpack you…

HTML5 Boilerplate

HTML5 Boilerplate is a professional front-end template for building fast, robust, and adaptable web apps or sites.

This project is the product of over 10 years of iterative development and community knowledge. It does not impose a specific development philosophy or framework, so you're free to architect your code in the way that you want.

• Homepage: https://html5boilerplate.com/
• Source: https://github.com/h5bp/html5-boilerplate
• Twitter: @h5bp

Quick start

Choose one of the following options:

• Download the latest stable release from html5boilerplate.com. This zip file is a snapshot of the dist folder. On Windows, Mac and from the file manager on Linux unzipping this folder will output to a folder named something like html5-boilerplate_v7.3.0. From the command line will need to create a folder and unzip the contents into that folder.

  mkdir html5-boilerplate
  unzip html5-boilerplate*.zip -d html5-boilerplate

• Clone the git repo — git clone https://github.com/h5bp/html5-boilerplate.git - and checkout the tagged…

Airbnb JavaScript Style Guide() {

A mostly reasonable approach to JavaScript

Note: this guide assumes you are using Babel, and requires that you use babel-preset-airbnb or the equivalent. It also assumes you are installing shims/polyfills in your app, with airbnb-browser-shims or the equivalent.

This guide is available in other languages too. See Translation

About this book

This is a book on the functional paradigm in general. We'll use the world's most popular functional programming language: JavaScript. Some may feel this is a poor choice as it's against the grain of the current culture which, at the moment, feels predominately imperative. However, I believe it is the best way to learn FP for several reasons:

• You likely use it every day at work.

  This makes it possible to practice and apply your acquired knowledge each day on real world programs rather than pet projects on nights and weekends in an esoteric FP language.

• We don't have to learn everything up front to start writing programs.

  In a pure functional language, you cannot log a variable or read a DOM node without using monads. Here we can cheat a little as we learn to purify our codebase. It's also easier to get started in this…

Introduction

swr.vercel.app

SWR is a React Hooks library for remote data fetching.

The name “SWR” is derived from stale-while-revalidate, a cache invalidation strategy popularized by HTTP RFC 5861.
SWR first returns the data from cache (stale), then sends the fetch request (revalidate), and finally comes with the up-to-date data again.

It features:

• Transport and protocol agnostic data fetching
• Fast page navigation
• Revalidation on focus
• Interval polling
• Request deduplication
• Local mutation
• Pagination
• TypeScript ready
• SSR support
• Suspense mode
• React Native support
• Minimal API

...and a lot more.

With SWR, components will get a stream of data updates constantly and automatically. Thus, the UI will be always fast and reactive.

Quick Start

import useSWR from 'swr'
function Profile () {
  const { data, error } = useSWR('/api/user', fetcher)
  if (error) return <div>failed to load<

Solid is a declarative JavaScript library for creating user interfaces. It does not use a Virtual DOM. Instead it opts to compile its templates down to real DOM nodes and wrap updates in fine grained reactions. This way when your state updates only the code that depends on it runs.

Key Features

• Real DOM with fine-grained updates (No Virtual DOM! No Dirty Checking Digest Loop!).
• Declarative data
  • Simple composable primitives without the hidden rules.
  • Function Components with no need for lifecycle methods or specialized configuration objects.
  • Render once mental model.
• Fast! Almost indistinguishable performance vs optimized painfully imperative vanilla DOM code. See Solid on JS Framework Benchmark.
• Small! Completely tree-shakeable Solid's compiler will only include parts of the library you use.
• Supports modern features like JSX, Fragments, Context, Portals, Suspense, SSR, Error Boundaries and Asynchronous Rendering.
• Built on TypeScript.
• Webcomponent friendly
  • Context API that spans Custom Elements

Machine Learning Systems Design

This booklet covers four main steps of designing a machine learning system:

1. Project setup
2. Data pipeline
3. Modeling: selecting, training, and debugging
4. Serving: testing, deploying, and maintaining

It comes with links to practical resources that explain each aspect in more details. It also suggests case studies written by machine learning engineers at major tech companies who have deployed machine learning systems to solve real-world problems.

At the end, the booklet contains 27 open-ended machine learning systems design questions that might come up in machine learning interviews. The answers for these questions will be published in the book Machine Learning Interviews. You can look at and contribute to community answers to these questions on GitHub here. You can read more about the book and sign up for the book's mailing list here.
