Over the course of the past year, the V8 team has developed a new method for measuring performance against snapshots of real web pages. Using insights from real-world measurements, the V8 team improved the speed of the average page load in Chrome by 10-20% over the course of the past year. 另附：V8 - Retiring Octane、Chrome - Scroll anchoring for web developers.
PhantomJS - Stepping down as maintainer
Headless Chrome is coming. I think people will switch to it, eventually. Chrome is faster and more stable than PhantomJS. And it doesn’t eat memory like crazy. I don’t see any future in developing PhantomJS. Developing PhantomJS 2 and 2.5 as a single developer is a bloody hell.
TypeScript at Slack
At Slack, we strive to be good open-source citizens. To that end, we strive to make the move to TypeScript easier for other developers: Whenever we find gaps, we try to close them. 另：TypeScript 2.3 已经 发布 RC 版了.

Creating a Modern OCR Pipeline Using Computer Vision and Deep Learning
In this post we will take you behind the scenes on how we built a state-of-the-art Optical Character Recognition (OCR) pipeline for our mobile document scanner. We used computer vision and deep learning advances such as bi-directional Long Short Term Memory (LSTMs), Connectionist Temporal Classification (CTC), convolutional neural nets (CNNs), and more. In addition, we will also dive deep into what it took to actually make our OCR pipeline production-ready at Dropbox scale.
The Ultimate Guide to Becoming a CTO
Becoming a CTO is really hard. There is nothing more valuable than a real experience, but in addition to the experience, you can find a ton of useful resources over the internet to help you get started. Therefore we’ve put together an amazing list of (recommended by other CTOs) resources (blog posts, books, presentations, videos etc.). The reason why we’re doing this is to help you to become a better CTO/Technical Leader in your startup or company.
So what’s this GraphQL thing I keep hearing about?
GraphQL is a syntax that describes how to ask for data, and is generally used to load data from a server to a client. GraphQL has three main characteristics: It lets the client specify exactly what data it needs; It makes it easier to aggregate data from multiple sources; It uses a type system to describe data. So how did GraphQL get started? What does it look like in practice? And how do you start using it? Read on to find out!
ECharts GL 1.0 alpha 发布
距离 ECharts-X 最近一个版本已经过去了两年多时间，期间我们不断被开发者在各种渠道询问 ECharts-X 为什么还不升级新版本，是不是不再维护了等等，对于这些问题我们只能回答我们还没准备好。尽管这两年时间 ECharts X 没什么动静，但是其它的工作，像 ECharts 3 的架构大改动和后续版本的迭代升级，以及其它 WebGL 产品的开发，都是对新版本架构和技术上的积累。现在我们终于可以说我们准备得差不多了，ECharts-X 的下一代，ECharts-GL 发布 1.0 alpha。
使用 FIS3 构建 Vue 前端工程. webpack 用户也请看过来
使用 FIS 进行更细致的打包，不过其实 FIS 支持自动分析依赖的
这篇文章对 erlang 的介绍挺有意思的，尤其是 erlang 的设计哲学，很多都可以当做系统设计原则来用。
如何处理好前后端分离的 API 问题
API 的维护是一件烦人的事，所以最好能一次设计好 API。可是这是不可能的，API 在其的生命周期里，应该是要不断地演进的。它与精益创业的思想是相似的，当一个 API 不合适现有场景时，应该对这个 API 进行更新，以满足需求。也因此，API 本身是面向变化的，问题是这种变化是双向的、单向的、联动的？还是静默的？API 设计是一个非常大的话题，这里我们只讨论：演进、设计及维护
文本数据可视化 - 从 Wordle 谈起

The Psychology of Speed
Why do people leave a website? There could be many reasons, such difficulty finding what they are looking for. But there’s a good chance users leave a site because it feels too slow to load. In this section, I want to draw some attention to psychology, and how it plays a big role in our perception of speed and performance.
How We Track Pageviews Is All Wrong
The reality is the web has changed a lot in the last 10-15 years, and more and more websites don’t fit this traditional model. Our analytics tools haven’t kept up. Analytics tools should measure user engagement, and they shouldn’t be coupled to site implementation. When the user experience improves, we should be able to prove it via our analytics reports. This is the most straightforward way to make the business case for progress.
A Comprehensive Guide To HTTP/2 Server Push
In this article, you’ll learn all about server push, from how it works to the problems it solves. You’ll also learn how to use it, how to tell if it’s working, and its impact on performance. Let’s begin!
How we made our DNS stack 3x faster
Cloudflare is now well into its 6th year and providing authoritative DNS has been a core part of infrastructure from the start. Last year we decided to replace two core elements of our DNS infrastructure: the part of our DNS server that answers authoritative queries and the data pipeline which takes changes made by our customers to DNS records and distributes them to our edge machines across the globe. The rough architecture of the system can be seen above.
Debugging Tips and Tricks
I have a few tips and tricks I rely on pretty heavily and found that I give the same advice again and again during workshops, so here’s a compilation of some of them, as well as some from the community. We’ll start with some core tenets and then drill down to more specific examples.
Mastering the Node.js CLI & Command Line Options
V8 plan for Node.js LTS Carbon (A potential path to TurboFan + Ignition)
V8 5.9 will be the first version with TurboFan + Ignition (TF+I) turned on by default. As parts of the Node.js codebase have been tuned to CrankShaft, there will be a non trivial amount of churn to adapt to the new pipeline. This also creates a security risk as CrankShaft and FullCodeGen are no longer maintained by the V8 team or tested by the Chrome security team.
Anbox - Android in a Box
Anbox puts the Android operating system into a container, abstracts hardware access and integrates core system services into a GNU/Linux system. Every Android application will behave integrated into your operating system like any other native application.
What’s new in Microsoft Edge in the Windows 10 Creators Update
This release updates the Windows web platform to EdgeHTML 15, the fourth release of EdgeHTML and a major step forward both in terms of the browser user experience, web platform capabilities, and fundamentals like performance, efficiency, and accessibility. In this post, we’ll share a quick overview of what’s new in each area, for both users and web developers.
Ionic 3.0 has Arrived!
We are so excited to announce the release of Ionic 3.0! This version jump may worry some of you, but don’t let it! The required changes to go from 2.x.x to 3.0.x are minimal.

Color Tool - Material Design
Create, share, and apply color palettes to your UI, as well as measure the accessibility level of any color combination.
Musical User Interfaces
This is an ongoing set of projects focused on better interfaces for music software. The goal is to re-think many of the ways in which audio software is designed. These are a set of prototypes for how we might interact with music software more fluently, to better realise our ideas, and encourage creativity. The primary concern is not about the quality of DSP, or the way things sound, but how we use and interact with our tools.
方程式又一波大规模 0day 攻击泄漏
Shadow Brokers再次泄露出一份震惊世界的机密文档，其中包含了多个精美的 Windows 远程漏洞利用工具，可以覆盖大量的 Windows 服务器，一夜之间所有Windows服务器几乎全线暴露在危险之中，任何人都可以直接下载并远程攻击利用，考虑到国内不少高校、政府、国企甚至还有一些互联网公司还在使用 Windows 服务器，这次事件影响力堪称网络大地震。不过，微软宣布已修复来自NSA的Windows漏洞。
Nginx reaches 33.3% web server market share while Apache falls below 50%
Half of the web still runs on Apache’s web server, but one third already uses Nginx, and the gap is closing fast. We have a closer look at the detailed statistics and trends.
My textbook manifesto is so simple it sounds stupid. Here it is: Students should read and understand textbooks. That’s it. It’s hard to imagine that anyone would disagree, but here’s the part I find infuriating: the vast majority of textbook authors, publishers, professors, and students behave as if they do not expect students to read or understand textbooks.
Qt binding for Go (Golang)
Qt is a cross-platform application framework that is used for developing application software that can be run on various software and hardware platforms with little or no change in the underlying codebase, while still being a native application with native capabilities and speed. Qt binding for Go (Golang) with support for Windows / macOS / Linux / Android / iOS / Sailfish OS / Raspberry Pi / AsteroidOS. 在跨平台 GUI 程序开发领域 qt 是除了 web 外的另一大分支。

How to Study: A Brief Guide
I am going to give you some suggestions on how to study efficiently. They worked for me when I was in high school, college, and graduate school. Not only that, but they worked equally well for me in humanities courses (like philosophy and literature) and in science courses (like math and computer science).
