The whole web at maximum FPS: How WebRender gets rid of jank
With WebRender, we want apps to run at a silky smooth 60 frames per second (FPS) or better no matter how big the display is or how much of the page is changing from frame to frame. And it works. Pages that chug along at 15 FPS in Chrome or today’s Firefox run at 60 FPS with WebRender. So how does WebRender do that? It fundamentally changes the way the rendering engine works to make it more like a 3D game engine.
Building Browser Extensions At Scale
Over ten million people use the Grammarly Chrome extension. Our Firefox, Safari and Edge extensions are incredibly popular, too. These extensions may look easy on the outside because they are low profile and easy to use. But it is actually a complex product supported by a full team of engineers. We have been developing and perfecting it for 6 years. Along the way we have learned a thing or two that we’d like to share. This article is intended to be an overview of our learnings and best practices on a broad range of topics.
Node.js State of the Union 2017
Overall, Node.js is in a good place, but we can and will be better. We need to evaluate our systems and structures to make sure we are ready for the next 8 million Node.js instances and to help encourage a better more effective community and collaboration. Our future relies on our ability to adapt and nurture that success and drive toward a stronger ecosystem that involves more developers, solution providers and others who can continue the work that has been done to date. 另附：Node.js Foundation Readies Official Developer Certification.

Setting up Webpack, Babel and React from scratch, revisited
Last summer I wrote this post which quickly became my most popular one to day. With webpack 2 and 3 it got outdated, so I decided to write a new one.
A SIMPLE APPROACH TO BUILDING A REAL-TIME COLLABORATIVE TEXT EDITOR
This post is my attempt to write an easy to understand introduction to the main ideas behind building a real-time collaborative text editor, which can be tricky as you want all clients to synchronize and see a sensible result even in the face of concurrent edits. In some ways, this is already a solved problem by Operational Transform (OT) and open-source implementations like Firepad and ShareJS.

Image Effects with CSS
Using one or more newer CSS properties (background-blend-mode, mix-blend-mode, or filter) gives us a surprising amount of possibilities to manipulate a single source image.
iPhone X notch advice for web developers
Notches become necessary on edge-to-edge screen devices, if the device is to have any front-facing sensors. This Essential notch is a lot smaller than the iPhone X notch, since it only needs to accommodate a camera, while the iPhone’s notch houses a more complex and ultimately wider sensor array (including a Kinect-like depth-measuring sensor). 另附：UI Design for iPhone X: Top Elements and the Notch

There’s no need to climb a mountain — we’ve got your 10 commandments of mobile app design right here.
UX for Lizard Brains
The remainder of this article introduces three ways to design digital objects that “play nice” with our evolved expectations of the physical world. By doing our best to concretize the dematerialized things of our screen-based world, we give our lizard brains better affordances for understanding.
Don’t Let Your Brain Deceive You: Avoiding Bias In Your UX Feedback
There are dozens of cognitive biases that take many different forms, although a few dominating types emerge frequently for product teams seeking user feedback. In this article, we’ll take a closer look at four of the most common types of cognitive biases that pop up when collecting and interpreting UX feedback — and how you can nip these biases in the bud, before they skew your production process.
Keeping track of letter-spacing, some guidelines

OpenTracing: An Open Standard for Distributed Tracing
Although tracing offers visibility into an application as processes grow in number, instrumenting a system for tracing has thus far been labor-intensive and complex. The OpenTracing standard changes that, enabling the instrumentation of applications for distributed tracing with minimal effort.
MongoDB: How to Build a Global Database as a Service
Atlas is MongoDB’s database as a service. Learn how they leverage AWS to provide a scalable, available and secure service to thousands of customers across the globe. Atlas deploys EC2 based MongoDB clusters across multiple Availability Zones in customer dedicated VPCs. Customers with their own VPCs can then use VPC Peering to privately reach their MongoDB clusters. We also discuss how detailed monitoring, automatic backups, no-downtime patching, and push-button scaling work at this scale.
Next.js 4: React 16 and styled-jsx 2
We are happy to introduce Next.js 4, which features support for React 16 and introduces a major upgrade for the default styling engine styled-jsx with support for dynamic styles. Major performance improvements are introduced: SSR with Next.js 4 is 2.6x faster and style initialization is 20% faster. According to CSS-in-JS benchmarks, Next.js styles are now the fastest of any library.

Ansible open sources Ansible Tower with AWX
Ever since Red Hat acquired Ansible, I and many others have anticipated whether or when Ansible Tower would be open sourced. Ansible Tower is one of the nicest automation tools I’ve used… but since I haven’t been on a project with the budget to support the Tower licensing fees, I have only used it for testing small-scale projects.
The Intuitive Guide to Data Structures And Algorithms
This guide is focused on—giving you a visual, intuitive sense for how data structures and algorithms actually work. So if you’ve got a big coding interview coming up, or you never learned data structures and algorithms in school, or you did but you’re kinda hazy on how some of this stuff fits together… This guide will fill in the gaps in your knowledge and make you say, “Oooh, that’s how that works.”
This is a straight-to-the-point distilled list of technical interview Do’s and Don’ts, mainly for algorithmic interviews. Some of these may apply to only phone screens on whiteboard interviews but most will apply to both. I revise this list before each of my interviews to remind myself of them and eventually internalized all of them to the point I do not have to rely on it anymore.

新零售，就是“用互联网的效率回到线下”，就是让线下的“体验性”和“即得性”优势，插上“效率”的翅膀。我们对这个“效率”有极致要求，那就是让线下的小米之家，和线上的小米商城，实现同款同价。这就是“小米的新零售”。电商认为：零售=流量x转化率x客单价x复购率。线下开店，上门推销，电话销售，校门口摆摊，一切的零售形态，其实最终都可以用这个公式来表示。对应到“电商对零售的理解”，坪效 =（流量x转化率x客单价x复购率）/ 面积。极致的坪效，是小米新零售的关键。
