Google’s Flutter = React + Java Swing
Google has recently announced its new mobile UI framework called Flutter. It allows you to create native-ish mobile apps that run on Android, iOS and Google’s new Fuchsia operating system.

Techniques for decomposing React components
React components have a lot of power and flexibility. With so many tools at your disposal, it is incredibly easy for components to grow over time, become bloated and do too much. As with any other kind of programming, adhering to the single responsibility principle not only makes your components easier to maintain, but also allows for greater reuse. However, identifying how to separate the responsibilities of a large React component is not always easy. Here are three techniques to get you started, from the simplest to most advanced.

webpack 3: Official Release!!
虽然号称 98% 的用户不受影响,但实际上…

San - 一个传统的MVVM组件框架
百度推出的 MVVM 框架,甚至兼容 IE6. 如果拿车来比喻,我们想造的是一台陆巡。相比轿车甚至多数SUV,它没有那么好开,看不到很多 2.0T 的车尾灯;相比牧马人和 benz G,他越野能力和通过性也没那么强。但是它很可靠,能稳稳当当、舒适地带你到任何想去的地方。

12 原则由公有云 PaaS 的先驱 Heroku 于 2012 年提出([原文参见 ),目的是告诉开发者如何利用云平台提供的便利来开发更具可靠性和扩展性、更加易于维护的云原生应用。距离 12 原则的提出已有五年之久,12 原则的有些细节可能已经不那么跟得上时代,也有人批评 12 原则的提出从一开始就有过于依赖 Heroku 自身特性的倾向,不过不管怎么说,12 原则依旧是业界最为系统的云原生应用开发指南,我们可以把它作为一个非常有力的参考,但是也千万不要教条。


随着移动化联网浪潮的汹涌而来与浏览器性能的提升,iOS、Android、Web 等前端开发技术各领风骚,大前端的概念也日渐成为某种共识。虽然具体的代码实现、使用的技术不同,但是 Android、iOS 以及 Web 乃至于 React Native 等开发中,我们需要解决的问题、能够用到的架构设计模式都是可以相互借鉴的。 在我们从某个领域迁移到其他领域时,我们能很方便地知道应该学习些什么,不同的技术、工具他们的职责是什么,应该选择怎样的架构或者设计模式。

JavaScript?我不是应该使用 Python 吗?甚至 Scikit-learn 在 JavaScript 上都不工作。这是可能的,实际上,连我自己都惊讶于开发者对此忽视的态度。就 Scikit-learn 而言,Javascript 的开发者事实上已经推出了适用的库,它会在本文中有所提及。那么,让我们看看 Javascript 在机器学习上能够做什么吧。

A new approach to text rendering
In Atom 1.19, we’re landing a complete rewrite of the text editor’s DOM interaction layer that improves rendering performance and simplifies the code. Prompted by the availability of some valuable new DOM APIs with the upgrade to Electron 1.6, we decided to start over from the beginning and take a critical look at the structure and performance every aspect of our DOM interaction.

Connect: behind the front-end experience
In this blog post, we’ll describe how we used several next-generation web technologies to bring Connect to life, and walk through some of the finer technical details (and excitement!) on our front-end journey.

ES2017’s async/await is the best thing to ever happen to JavaScript
Eventually I began understanding the idea of functions as values, that could be written inline, and passed to other functions as options. A callback was essentially a ‘what to do next’ action. I understood callbacks, and learned common async patterns. I liked learning a lot about functions, scope, and closures. I used, but never liked callbacks: a nagging doubt said this is the VMs job, not the programmers.

Intern and JavaScript Testing in 2017
Intern was created to alleviate this problem and to provide a solid glue architecture for testing applications using JavaScript and various asynchronous patterns such as Promises. Intern has certainly helped us and our users test their applications far more efficiently than was previously possible. As the world of JavaScript evolved, though, we noticed that writing quality tests was getting more difficult.

What Does a Well-Documented CSS Codebase Look Like?
A well-documented CSS codebase enforces consistency, boosts maintainability, and helps the team to build a shared vocabulary. So, here we go! Let’s examine the 4 big signs of a well-documented CSS codebase: CSS Tech Stack & Toolchain; CSS Conventions; CSS Architecture; CSS Component Descriptions and Examples.

Functional programming in Javascript is an antipattern
I’m going out on a limb and calling functional programming in Javascript an antipattern. It’s an attractive path that gives way to a maze. It seems to solve some problems but ends up creating more. More importantly, those problems appear to have no higher-level solution that can prevent me from having to deal with them over and over again.

The State of Angular and the Due Date of Version 5
In this article, we will take a high level overview of the 4.x.x versions, see the scheduling of the upcoming versions, discover the due date of the new Angular baby — Version 5, and we will review on two more surprises that are provided by Angular.

JavaScript for Microcontrollers and IoT
The low-end nature of certain microcontroller platforms makes it somewhat difficult for beginners to use JavaScript. In this post we will take a brief look at the different options for running JavaScript on small devices, and we will also pick one of them and get one JavaScript engine running on it.

Site Speed Monitoring in A/B Testing and Feature Ramp-up
Predicting site speed impact of a feature rollout is a difficult engineering problem, particularly at scale. We are ramping hundreds of changes simultaneously through A/B testing. When ramping a feature into production, how can developers gain visibility into the site speed impact? Likewise, when a performance optimization is enabled in production, how can the developer quantify the benefit? In addition, how can performance degradation be detected at an early stage of feature ramp-up, before the impact spreads out to a larger audience? In this blog, we share our experiences and solutions here at LinkedIn.

Evolution of Dropbox’s Edge Network
Since launching Magic Pocket last year, we’ve been storing and serving more than 90 percent of our users’ data on our own custom-built infrastructure, which has helped us to be more efficient and improved performance for our users globally.

Content Popularity for Open Connect
There are many reasons why Netflix cares about the popularity of our TV shows and movies. On the Open Connect Content Delivery team, we predict content popularity to maximize our infrastructure efficiency. From the Content Delivery perspective, we view popularity as the number of times a piece of content is watched. We compute it by dividing total bytes streamed from this asset by the size in bytes of the asset.

Designing The Perfect Accordion
Design patterns can be extremely helpful, mostly because they save time and get us better results, faster. This series of articles is a summary of observations and experiments made throughout the time. Tighten up your seat belts: in this new series of articles on SmashingMag, we’ll look into examples of everything from carousels to filters, calculators, charts, timelines, maps, multi-column tables, almighty pricing plans all the way to seating selection in airline and cinema websites. But before we head off to complex interface problems, let’s start with something seemingly simple and obvious: an accordion.

10 Tips On Typography in Web Design
More than 95% percent of information on the web is in the form of written language. Good typography makes the act of reading effortless, while poor typography turns users off. Optimizing typography is optimizing readability, accessibility, usability(!), overall graphic balance. In this article, I will provide a set of rules that help you improve readability and legibility of your text content.

Tabs, spaces and your salary - how is it really?
This blog post is my attempt to shed some light into the issue. The original article encouraged people to explore the data for themselves and this is precisely what I did. So I’d like to invite you to follow me through a little data science detective story and a deep dive into the data from the Stack Overflow survey. You’ll see that tabs and spaces are not what they seem. Spoiler: your salary has more to do with the type of company and the environment you work in rather than what type of indentation you use.

Why use SemVer?
npm’s documentation recommends that you use semantic versioning, which we also call semver, but it doesn’t explain why you’d use SemVer in the first place. This post is a quick overview of SemVer and why it’s a good idea.

Why we’re betting against real-time team messaging
This post is the story of why we stopped using Slack. It’s also the story of how we had the (possibly) crazy idea that we could contribute something fundamentally different to an already cluttered team communication market - Twist. Something for teams like ours with the audacity to think that maybe there’s more to work than keeping up with group chat…
