Introducing the New Firefox: Firefox Quantum
https://blog.mozilla.org/blog/2017/11/14/introducing-firefox-quantum/
It’s fast. Really fast. Firefox Quantum is over twice as fast as Firefox from 6 months ago, built on a completely overhauled core engine with brand new technology stolen from our advanced research group, and graced with a beautiful new look designed to get out of the way and let you do what you do best: surf a ton of pages, open a zillion tabs, all guilt free because Firefox Quantum uses less memory than the competition.

Taming architecture complexity in V8 — the CodeStubAssembler
https://v8project.blogspot.ca/2017/11/csa.html
In this post we’d like to introduce the CodeStubAssembler (CSA), a component in V8 that has been a very useful tool in achieving some big performance wins over the last several V8 releases. The CSA also significantly improved the V8 team’s ability to quickly optimize JavaScript features at a low-level with a high degree of reliability, which improved the team’s development velocity.

The Cost Of JavaScript
https://medium.com/dev-channel/the-cost-of-javascript-84009f51e99e
As we build sites more heavily reliant on JavaScript, we sometimes pay for what we send down in ways that we can’t always easily see. In this post, I’ll cover why a little discipline can help if you’d like your site to load & be interactive quickly on mobile devices. tl;dr: less code = less parse/compile + less transfer + less to decompress

In this post we’ll break down the “Redirects (Auth)” example on the React Router documentation to learn how to create authenticated routes (routes that only certain users can access based on their authentication status) using React Router.

Getting from Redux to a state machine
http://krasimirtsonev.com/blog/article/getting-from-redux-to-state-machine-with-stent
This article is about Stent - a Redux-liked library that creates and manages state machines. Stent implements some of the Redux’s core ideas and in fact looks a lot like it. At the end of this post we will see that both libraries have a lot in common. Stent is just using state machines under the hood and eliminates some of the boilerplate that comes with Redux’s workflow.

How Discord Resizes 150 Million Images Every Day with Go and C++
https://blog.discordapp.com/how-discord-resizes-150-million-images-every-day-with-go-and-c-c9e98731c65d
Despite being a voice and text chat app, Discord sees over a hundred million images passing through its tubes every day. While we wish it was as simple as sending them out across the tubes to your friends, delivering these images creates some pretty large technical problems. Linking directly to images would leak users’ IP addresses to image hosts, and large images use up lots of bandwidth. To circumvent these problems, Discord needs an intermediary service to fetch images on behalf of users and then resize them to reduce bandwidth usage.

Open/R: Open routing for modern networks
https://code.facebook.com/posts/291641674683314/open-r-open-routing-for-modern-networks/
We are open-sourcing Open/R, a routing platform that enables rapid innovation in network functions. Open/R was originally built for the Terragraph wireless backhaul network, but we quickly saw its potential use for Facebook’s backbone, where it provides more efficient and precise control of a global fiber network. Now, we are even starting to roll it out into our data center fabrics, running inside FBOSS and on our Open Compute Project networking hardware like Wedge 100. Open/R is a single platform that spans a wide variety of network domains and designs, and we are looking to apply it in even more use cases.

Introducing container-diff, a tool for quickly comparing container images
http://opensource.googleblog.com/2017/11/container-diff-for-comparing-container-images.html
The Google Container Tools team originally built container-diff, a new project to help uncover differences between container images, to aid our own development with containers. We think it can be useful for anyone building containerized software, so we’re excited to release it as open source to the development community.

Announcing TensorFlow Lite
https://developers.googleblog.com/2017/11/announcing-tensorflow-lite.html
TensorFlow has always run on many platforms, from racks of servers to tiny IoT devices, but as the adoption of machine learning models has grown exponentially over the last few years, so has the need to deploy them on mobile and embedded devices. TensorFlow Lite enables low-latency inference of on-device machine learning models.另附:On-Device Conversational Modeling with TensorFlow Lite.

Best tech for a web site 2018? (PHP, Rails, Django, Node, Go, etc.)
https://news.ycombinator.com/item?id=15685905
Back in the day, PHP was a great tool for getting a site up quickly. Then Ruby on Rails took off in 2006 and took the lead. It was the “batteries included” of web frameworks. You could build a CRUD app very quickly. Many other language frameworks followed and evolved. It is almost 2018. What do you think is the best tech for a web app these days?

Cloud Native Storage: A Primer
https://thenewstack.io/state-cloud-native-storage/
The cloud-native architecture originating in hyper-scale cloud applications revolves around microservices, i.e. small stateless and decoupled application fragments. Many similar microservice instances can be deployed (using Docker or Kubernetes) to address service elasticity and resiliency. Multiple tiers of microservices are part of a bigger and evolving application.另附:The InfoQ eMag: Cloud Native

Products Over Projects
https://martinfowler.com/articles/products-over-projects.html
Software projects are a popular way of funding and organizing software development. The organize work into temporary teams and are funded with specific benefits projected in a business case. Product-mode instead uses durable teams working on a persistent business issue. Product-mode allows teams to reorient quickly by using short-cycle iterations while maintaining the architectural integrity of their software to preserve their long-term effectiveness.

The cargo cult of versioning
http://akkartik.name/post/versioning
In particular, Semantic Versioning is misguided, an attempt to fix something that is broken beyond repair. The correct way to practice semantic versioning is without any version strings at all, just Rich Hickey’s directive: if you change behavior, rename. Or ok, keep a number around if you really need a security blanket.

Mobile Interface Myths You Should Throw Out The Window
https://www.smashingmagazine.com/2017/11/mobile-interface-myths/
Having white-labeled design and marketing work for ad agencies for a few years, I’ve heard the following statements boldly proclaimed as unquestionable truths more times than I can count. From my experience with ad teams and client meetings, these are the most frequent myths I think we need to put to bed, or at least remember to evaluate case by case. Let’s take some time to cover five mobile interface myths you’ve probably been sold on (and why that might be a bad thing).

Code together in real time with Teletype for Atom
https://blog.atom.io/2017/11/15/code-together-in-real-time-with-teletype-for-atom.html
Social coding shouldn’t have to be this hard! Today, we’re taking a first step toward making it just as easy to code together as it is to code alone with Teletype for Atom. At the dawn of computing, teletypes were used to create a real-time circuit between two machines so that anything typed on one machine appeared at the other end immediately. Following in these electro-mechanical footsteps, Teletype for Atom wires the keystrokes of remote collaborators directly into your programming environment, enabling conflict-free, low-latency collaborative editing for any file you can open in Atom. 另附:Introducing Visual Studio Live Share.

Minify
https://github.com/tdewolff/minify
Minify is a minifier package written in Go. It provides HTML5, CSS3, JS, JSON, SVG and XML minifiers and an interface to implement any other minifier. Minification is the process of removing bytes from a file (such as whitespace) without changing its output and therefore shrinking its size and speeding up transmission over the internet and possibly parsing. The implemented minifiers are high performance and streaming, which implies O(n).

你真的理解“小步快跑、敏捷迭代”吗
https://mp.weixin.qq.com/s?__biz=MzA5MTMyNzAzMQ==&mid=2651542868&idx=1&sn=8e6d2fd4a77265ff4d78a65050f49960 “最小可行性产品”的核心要义不在于寻找“最小产品”,而在于“佐证假设”,因此“最小可行性产品”不是一个产品,它是一个求证的过程。“最小”是一个相对概念,不是绝对限定值。不能轻易地认为“最小可行性”产品中的“最小”就是最精简的功能、最简陋的流程、最易于上线的路径,这样就可以快速迭代、小步快跑了。不同的产品,定位与所需要解决的关键痛点不同,其涉及的“小”的概念和范畴也是不同的。探索“最小”的过程,需要你回答并且精准地提炼出你想要验证的产品的“功能特性”、“卖点”、“构成要素”、“关系链”,这个过程就是提出“假设”的过程,当你完成了假设之后,需要用“做减法”的方式提炼选出最核心的功能卖点,然后拿此卖点到市场上去验证,这个过程就是进行“佐证”的过程。
