附：All Talks from ng-conf 2018
So, let’s talk about very large applications and the things they have in common. Certainly that there might be a lot of developers. It might be a few dozens or even more–and these are humans with feelings and interpersonal problems and you may have to factor that in.
What You Can Expect From Node.js 10
Announcing NGINX Unit 1.0

It’s time to rebuild the web
The web was never supposed to be a few walled gardens of concentrated content owned by a few major publishers; it was supposed to be a cacophony of different sites and voices.

Gimel: PayPal’s Analytics Data Processing Platform
Besides being unable to find the correct datasets, developers, analysts and data scientists don’t want to deal with the code to read and write data, and obviously want to focus their attention and time towards dataset development, analysis and exploration. We built the Gimel Data Platform – the centralized metadata catalog PCatalog and the unified Data API – to address these challenges and help commoditize data access in the big data world.
Samza Aeon: Latency Insights for Asynchronous One-Way Flows
You can’t fix something if you don’t know there’s a problem. Measuring and tracking the latency of requests through your system is essential to identifying and resolving issues quickly. In order to measure these asynchronous one-way flows, we built a tool called Aeon using Samza, an open source stream processing system developed here at LinkedIn, which we use to gain latency insights across these flows. In this blog post, we’ll describe how we built Aeon and the importance of asynchronous delay monitoring.

Distributed architecture concepts I learned while building a large payments system
In this post, I am summarizing some of the concepts that I have found essential to learn and apply when building a large scale, highly available and distributed system: the payments system that powers Uber. This is a system with a load of up to thousands of requests per second, where critical payments functionality needs to work correctly, even if parts of the system are down. 另附：Google: A Collection Of Best Practices For Production Services
Probability Theory (For Scientists and Engineers
Formal probability theory is a rich and complex field of mathematics with a reputation for being confusing if not outright impenetrable. Much of that intimidation, however, is due not to the abstract mathematics but rather how they are employed in practice. In particular, many introductions to probability theory sloppily confound the abstract mathematics with their practical implementations, convoluting what we can calculate in the theory with how we perform those calculations.

Apple open-sources FoundationDB
FoundationDB is a distributed datastore, designed from the ground up to be deployed on clusters of commodity hardware. These clusters scale well as you add machines, automatically heal from hardware failures, and have a simple API. The key-value store supports fully global, cross-row ACID transactions. That’s the highest level of data consistency possible. What does this mean for you? Strong consistency makes your application code simpler, your data models more efficient, and your failure modes less surprising. 另：MySQL 8.0 Released
wasm-pack is a tool for assembling and packaging Rust crates that target WebAssembly. These packages can be published to the npm Registry and used alongside other packages. This means you can use them side-by-side with JS and other packages, and in many kind of applications, be it a Node.js server side app, a client-side application bundled by Webpack, or any other sort of application that uses npm dependencies. 另附：Build your own web things with the Things Framework。另外，Firefox 还专门为 Facebook 做了一个插件：Facebook Container for Firefox - Prevent Facebook from seeing what websites you visit，话说 Facebook 最近很招人恨，见 Scuttlebutt, A Decentralized Alternative To Facebook、 No boundaries for Facebook data: third-party trackers abuse Facebook Login
Introducing GitHub Learning Lab: A new way to level up on GitHub
GitHub is more than a home for code. It’s a forum for collaboration, a sandbox for testing, a launchpad for deployment, and often, a platform for learning new skills. After training thousands of people to use Git and GitHub, the GitHub Training Team has established a tried-and-true method for helping new developers retain more information and ramp up quickly as they begin their software journeys. And now, we’re making those experiences accessible to developers everywhere with GitHub Learning Lab. 另附：Using Figma designs to build the Octicons icon library
Introducing GapminderVR: Data Visualization in Virtual Reality
I am a big fan of sites such as Gapminder and Our World in Data. Such data visualization sites are like intellectual pornography. You want to know which countries are doing better? Which continents drink more alcohol? How is alcohol related to GDP? Have people getting fatter recently, or is that a long trend? You don’t need to read thick books, you can just browse graphs.

NativeScript 4.0 is out!
With NativeScript 4.0 you can now use any View as the root of your application. Previously, the root of the app was always a Frame, in which you can navigate using Pages. Now, you have the flexibility to put a TabView or a RadSideDrawer as the root of the app. This enables many more commonly-used navigation patterns and also allows for creating a more optimized UI tree.

How AI Wipes Out UI
Only after we master the ability to materialize things from the air, utilize quantum computers to generate data, and operate machines with our minds, can we think of the real synergy with AI. Before that, our little robots will be our assistants and will do only what they’re supposed to do. 另附：Good Designer, Bad Designer
The long, incredibly tortuous, and fascinating process of creating a Chinese font
The default set for English-language fonts contains about 230 glyphs. A font that covers all of the Latin scripts—that’s over 100 languages plus extra symbols—contains 840 glyphs, according to Březina. The simplified version of Chinese, used primarily in mainland China, requires nearly 7,000 glyphs. For traditional Chinese, used in Taiwan and Hong Kong, the number of glyphs is 13,053. An experienced designer, working alone, can in under six months create a new font that covers dozens of Western languages. For a single Chinese font it takes a team of several designers at least two years.

Jupyter, Mathematica, and the Future of the Research Paper
The Atlantic has a great article on new ways to share research results. Its three parts make three points: A graphical user interface (GUI) can facilitate better technical writing; Wolfram’s proprietary notebook showcased innovative technology, but decades after its introduction, still has few users; Jupyter is a new open-source alternative that is well on the way to becoming a standard for exchanging research results. Each is spot on. I had to learn the hard way why so many kept their distance from Mathematica. Now, I’m much more productive with Jupyter. I’m experimenting with, and excited about, its potential as a way to write up research results. 另附：Interactive Go programming with Jupyter

过去一年，碎片化信息阅读越来越多了，但相比铺天盖地的头条、公众号文章，我更喜欢读书。碎片化的文章永远无法让人建立起一个对有深度的问题的真正的、系统的理解，比如 AI、比如区块链、比如黎曼假设。黎曼假设据说是数学中最深刻的未解问题，它说的是“Zeta 函数的所有非平凡零点的实部都是 1/2”，仅仅想搞清楚这句话到底是什么意思，它为什么那么重要，就足以激发无限的好奇心了。
