Domain-Oriented Observability
Observability in our software systems has always been valuable and has become even more so in this era of cloud and microservices. However, the observability we add to our systems tends to be rather low level and technical in nature, and too often it seems to require littering our codebase with crufty, verbose calls to various logging, instrumentation, and analytics frameworks. This article describes a pattern that cleans up this mess and allows us to add business-relevant observability in a clean, testable way.

The 2019 IPFS Roadmap
To ground our thinking about the next year, we first had to zoom out to the core mission of the IPFS project in the long-term. We take on many efforts and support many groups in our open source community, but it is all driven by the aim to make the internet more accessible, empowering, and useful for many years to come.

Distributed Application Architecture for Edge-Based Service Delivery
We have seen the revolution in software application development after containers arrived and CI/CD was started to adapt by IT firms. Now, as the focus of many enterprises and technology vendors started to shift to edge, a new architecture may evolve as distributed applications have a different environment with a different type of latency requirement. Managing such distributed applications that cross-platform boundaries are one of the most complex challenges facing the industry at this time. A goal of services in the edge-based environment should be to have the right application development environment in place for faster innovation for end consumers.

Web Components will replace your frontend framework
Create your own custom HTML tags that inherit all properties of the HTML elements they extend and which you can use in any supporting browser by simply importing a script. All HTML, CSS and JavaScript defined inside the component is fully scoped to the component itself. The component will show up as a single HTML tag in your browser’s dev tools with its styling and behaviour fully encapsulated, no workarounds, frameworks or transpiling needed. Let’s take a look at the main features of Web Components. 另附:Aurelia Unveils Its Web Components Plugin.

How We Used WebAssembly To Speed Up Our Web App By 20X
In this article, we explore how we can speed up web applications by replacing slow JavaScript calculations with compiled WebAssembly.


根据 ModuleCounts.com 的数据,Node 的包注册中心 NPM 每天会增加 507 个包,相比下一名要多 4 倍多。2018 年 Stack Overflow 调查也有类似的结果,JavaScript 是使用最广泛的语言,Node.js 是使用最广泛的框架。本节我会主要分享一些跟 Node.js 结合比较密切的点:首先介绍一下 API 演进与 GraphQL,然后讲一下 SSR 如何结合 API 落地,构建出具有 Node.js 特色的服务,然后再简要介绍下 Node.js 的新特性、新书等,最后聊聊我对Deno 的一点看法。

You probably don’t need that hip web framework
Every year, there’s something new to learn and play with in the web development world that’s considered something you must use: React, Vue, GraphQL, Docker, whatever it might be. And, every year I mess around with these new things and find myself stuck, regretting even trying to use them when I could have just launched something. The obsession with finding better frameworks is killing ideas before they reach the world, and nobody’s really talking about it.

Pure JavaScript Functions as a Replacement for Lodash
A brief overview of pure replacement functions over Lodash/Underscore.js.

Make it hard to screw up driven development
Developers say things like, “I’m just going to do this quick and dirty first,” because it’s taken as fact that if you code anything quickly, it not only will be prone to mistakes, but that you’ll be deliberately not honoring established conventions and skipping tasks that make for more solid code. There is probably no practical way to make it impossible to write sloppy, bad code, but it is fascinating to consider how tooling has evolved to make it harder. Let’s get all Poka-yoke on development.

Getting creative with the Console API!
Debugging in JavaScript has always been inseparably connected with the Console API, which is most of the time used only through console.log(). But, did you know that it doesn’t have to be this way? Hasn’t console.log() already bored you with its monolithic output? Do you want to make your logs better, to make them prettier? 💅 If so, follow me, as we’ll discover how colorful and playful Console API can really be!

Behind the Scenes: What makes Gatsby Great
Gatsby is great from a multititude of perspectives. Our community is great. The developer experience is great. The performance of the resulting application is great. Our documentation is great. And so on and so forth… if I were to focus on each of these areas, this post would become an overly long love letter that I’m not sure many would want to read.

Bottoms-Up: How the Pinterest growth team decentralizes its structure
On the growth team at Pinterest, we describe our structure as “bottoms-up”, meaning ideas and responsibilities flow throughout the team in a way that provides a lot of autonomy to work on the projects each person wants to tackle, across a variety of roles. The result is a team that is very scalable and flexible. And it means that each of us on the team has a lot of liberty to choose how we spend our time.

An intro to Infrastructure as Code
This post will focus on the basics of Infrastructure as Code (IaC), addressing a fundamental question that I’m often asked when speaking with folks who are new to the platform: “Can I use Terraform on CircleCI?” The answer is yes. Yes you can! The followup post will contain best practices for executing Terraform on CircleCI and address more sophisticated use cases.

The Unreasonable Effectiveness of SQL
In the years since Don Chamberlin and Ramond Boyce published SEQUEL: A Structured English Query Language relational model and SQL have been extended and adapted to a significant number of technologies: OLTP, OLAP, object databases, object-relational databases, and even NoSQL. SQL has inspired query language design for non-relational databases: SQL for object databases, SQL for object-relational, SQL for XML, SQL for spatial, SQL for search, SQL for JSON, SQL for timeseries, SQL for streams and so on. Every BI tool interacts with the data using variety of SQL. In fact, SQL is the most successful 4th generation language. 另附:Amazon consumer biz celebrates ridding itself of last Oracle database with tame staff party… and a Big Red piñata.

Request’s Past, Present and Future
Before I go into the details and reasoning I’ll get straight to the point. The most valuable thing request can do for the JavaScript ecosystem is to go into maintenance mode and stop considering new features or major releases. Apologies in advance to the other committers on request that have been doing their best to improve it, but it’s for the best.

I tried creating a web browser, and Google blocked me
After 4 months of waiting, that is the response I got from Widevine, Google’s DRM for web browsers, regarding a license agreement. For the last 2 years I’ve been working on a web browser that now cannot be completed because Google, the creators of the open source browser Chrome, won’t allow DRM in an open source project. 另附:谷歌:昔日屠龙者正在成为“恶龙”?

react-three-fiber 2.0
React-three-fiber is a small React renderer for Threejs. Why, you might ask? React was made to drive complex tree structures, it makes just as much sense for Threejs as for the DOM. Building a dynamic scene graph becomes so much easier because you can break it up into declarative, re-usable components with clean, reactive semantics. This also opens up the ecosystem, you can now apply generic packages for state, animation, gestures and so on. 另附:React Particles WebGL - A 2D/3D particle library built with React, Three.js and WebGL.

Ahead of Its Time, Behind the Curve: Why Evernote Failed to Realize Its Potential
Here are some of the things I’ll be exploring in this article: Why timing was so crucial to Evernote’s success, and how co-founder and former CEO Phil Libin’s vision for the product created vital tailwind for Evernote’s growth; How the company resisted investor pressure and remained true to their convictions about the value of Evernote as a freemium product; How Evernote lost sight of its original vision and how this almost doomed the company. The idea for Evernote began with the personal quest of its founder, Stepan Pachikov. He aimed to solve a giant problem: overcoming the limitations of human memory.

From Show HN to Series D
In this post, we wanted to give you a window into Segment’s journey in that first year; from the initial product launch, to our first hundred customers, to the pitch deck we used to raise our first funding. For all the startups out there in a similar boat, hopefully you can take something from our experience and apply it to your own.

每个好的 CEO 都应该是好的产品经理,但是,但是后面的话更重要。但是每个好的产品经理,都不一定是好的 CEO。因为我对这句话有很多深刻的感受。在这几年时间里,伴随着互联网的浪潮,有很多人取得了成功。但提及成功的原因,绝大部分人都会说,因为我们的产品好。不得不说,这是一种“拜产品教”,有一些人对产品的崇拜,陷入比较极端的境地。这难道有什么不对吗?

“成长型思维”的提出者,是斯坦福大学著名心理学教授 Carol Dweck。她还为此专门写了一本书,并受到比尔盖茨的推崇,书的英文名叫《mindset》,翻译成中文就叫做《终身成长》。Carol Dweck在书中列举了大量案例,分析了教育、体育、商业、人际关系等领域成功与失败的因素。并提出,归根结底,都是思维方式的不同,成功者是成长型思维,而失败者是固定型思维。两者思维模式最根本的区别是什么呢?一言以蔽之,成长型思维者,认为万事万物通过自己的参与都可以改变;因此,心智也在不断迭代强化,从而造就非凡人生。而固定型思维者,认为可控因素少的可怜,自己不过是洪流中的一片树叶。因此,心智在年轻尚轻就停止发育,一直守至终老,才与身体一起埋藏。
