FEX 技术周刊 - 2018/04/09
Last week, the npmjs.com website received the most ambitious update in its history. We said “cheerio” to the old hapi-and jQuery-based website, and “hello” to a state-of-the-art web application based on Spife and React.
Examples of everything new in ECMAScript 2016, 2017, and 2018
In this article, I’ll cover all 18 features that are listed in the TC39’s finished proposals that were added in ES2016, ES2017, and ES2018 (final draft) and show them with useful examples.
GitLab + Google Cloud Platform = simplified, scalable deployment
Get super-simple deployment for your app with GitLab and Google Cloud Platform (GCP): thanks to our integration with Google Kubernetes Engine (GKE), you can now get CI/CD and Kubernetes deployment set up with just a few clicks.. Now everyone can get automatic code quality, security testing, and no-configuration deployment.
Improved Docker Container Integration with Java 10
With the release of Java 10, the JVM now recognizes constraints set by container control groups (cgroups). Both memory and cpu constraints can be used manage Java applications directly in containers, these include: adhering to memory limits set in the container; setting available cpus in the container; setting cpu constraints in the container. Java 10 improvements are realized in both Docker for Mac or Windows and Docker Enterprise Edition environments.

F2 3.1 发布，开箱即用的移动端可视化解决方案
F2，源于 Fast & Flexible 两个单词首字母，是 AntV 家族中专为移动端定制、开箱即用的可视化解决方案。或许大家对我比较陌生，但是从 AntV 上线的那一天起我就已经出道了，那时候我有另外一个名字『G2-mobile』，我和 G2 师承一脉，尽得『图形语法』真传，主要用于满足对代码体积以及渲染性能要求严苛的移动端图表需求。
Node 为解决后端并发而生，但却无心插柳，成为大前端的基石。伴随大前端的发展，Node 也发展得越来越好，越来越重要，其应用场景从脚手架、辅助前端开发（比如 SSR、PWA 等）的快速开发实践，到 API 中间层、代理层，到专业的后端开发都有非常成熟的经验。另外，前端越来越复杂，后端服务化，今日的前端要面临更多的挑战，Node 全栈给大家更多可能，狼叔对此坚定不移。
本文将带大家了解什么是 mvvm，mvvm 的原理，以及近几年产生了哪些演变。同时借 mvvm 话题，拓展到对各类前端数据流方案的思考，形成对前端数据流整体认知，帮助大家在团队中更好地做技术选型。
PHP7已经发布, 如承诺, 我也要开始这个系列的文章的编写, 主要想通过文章让大家理解到PHP7的巨大性能提升背后到底我们做了什么, 今天我想先和大家聊聊zval的变化. 在讲zval变化的之前我们先来看看zval在PHP5下面是什么样子。
在这篇文章中，我来讲述一下为什么我不再碰 C++ 的故事。这是关于计算机语言设计经济学专题文章的起始点。这篇文章会讨论为什么一些真心不好的决策会被做出来，然后进入语言的基础设计之中，以及我们该如何修正这些问题。

Making a 100% Statically-Linked, Single-File Web App with React and Rust
We’re excited to release FlameScope: a new performance visualization tool for analyzing variance, perturbations, single-threaded execution, application startup, and other time-based issues. It has been created by the Netflix cloud performance engineering team and just released as open source, and we welcome help from others to develop the project further.
Scaling Uber’s Hadoop Distributed File System for Growth
Scaling our infrastructure while maintaining high performance was no easy feat. To accomplish this, Uber’s Data Infrastructure team massively overhauled our approach to scaling our HDFS by implementing several new adjustments and features, including View File System (ViewFs), frequent HDFS version upgrades, NameNode garbage collection tuning, limiting the number of small files that filter through the system, an HDFS load management service, and a read-only NameNode replica. Read on to learn how Uber implemented these improvements to facilitate the continued growth, stability, and reliability of our storage system.
How Ipdata Serves 25M API Calls From 10 Infinitely Scalable Global Endpoints
Our users typically call our API on each page request on their websites to geolocate their users and localize their content. So this particular failure was directly impacting our users’ websites on the biggest sales day of the year. This sequence of events and their inexplicable nature — cpu, mem and i/o were nowhere near capacity. As well as concerns on how well (if at all) we would scale, given our outage, were a big wake up call to rethink our existing infrastructure.
Updating the NGINX Application Platform
Today, our vision to simplify the journey to microservices takes a big step forward. We are announcing the upcoming availability of the next version of our flagship software, NGINX Plus R15, with exciting new features, and the upcoming launches of NGINX Unit 1.0 and NGINX Controller R1. Combined, these launches advance the NGINX Application Platform, a product suite that includes a load balancer, content cache, API gateway, WAF, and application server – all with centralized monitoring and management for monolithic apps, for microservices, and for transitional apps.
Introduction to Computer Vision
Computer Vision is the process of using machines to understand and analyze imagery (both photos and videos). While these types of algorithms have been around in various forms since the 1960’s, recent advances in Machine Learning, as well as leaps forward in data storage, computing capabilities, and cheap high-quality input devices, have driven major improvements in how well our software can explore this kind of content.

The Rise Of Intelligent Conversational UI
The importance of Conversational UI cannot be understated, even if some of us wish it wasn’t happening. The most important advancement in Conversational UI has been Natural Language Processing (NLP). This is the field of computing that deals not with deciphering the exact words that a user said, but with parsing out of it their actual intent. If the bot is the interface, NLP is the brain. In this article, we’re going to take a look at why NLP is so important, and how you (yes, you!) can build your own.
The Inside Story of Reddit’s Redesign
For the past year and a half, Reddit and its new team of 20 designers have been refashioning the so-called “front page of the internet.” They’ve taken great pains to build on top of Reddit’s long legacy, rather than replacing it with something unfamiliar. They’ve argued about everything from the placement of the logo to the way moderators should style their communities to the dominant color on the site (red-orange, as it turns out). It’s been a slow, careful process that everyone takes extremely seriously. “If you redesign Reddit,” says Diego Perez, the company’s head of design, “you’re inherently changing the internet.”
Announcing the new HTTP Archive!
Our goal was to more easily enable anyone to explore the health of the web as a whole. Not just data-mining SQL gurus or statisticians, but everyone with a vested interest in the state of the web. To that end, we’ve made several important enhancements to the HTTP Archive website to make discovering stats and trends about the web even easier.
Announcing 22.214.171.124: the fastest, privacy-first consumer DNS service
Cloudflare’s mission is to help build a better Internet. We’re excited today to take another step toward that mission with the launch of 126.96.36.199 — the Internet’s fastest, privacy-first consumer DNS service. This post will talk a little about what that is and a lot about why we decided to do it.

Introducing Network Error Logging
Enter Network Error Logging (NEL), a new web platform spec that we’re working on in the W3C’s Web Performance Working Group. With NEL, you can instruct user agents to collect the same set of information that would appear in your server logs. Those instructions would apply to all requests to your server’s origin, regardless of how (and on which containing sites) those requests were initiated. And since the data is collected directly by the user agent, you should have visibility into all of your clients’ connection requests, not just those that made it to your serving infrastructure.

The End of Windows
The story of Windows’ decline is relatively straightforward and a classic case of disruption: The Internet dramatically reduced application lock-in; PCs became “good enough”, elongating the upgrade cycle; Smartphones first addressed needs the PC couldn’t, then over time started taking over PC functionality directly. Thus my assertion at the top, that the story of how Microsoft came to accept the reality of Windows’ decline is more interesting than the fact of Windows’ decline; this is how CEO Satya Nadella convinced the company to accept the obvious.
