Monorepos: Please don’t!
https://medium.com/@mattklein123/monorepos-please-dont-e9a279be011b
As is often the case in software engineering, we tend to look at tech’s most successful companies for guidance on best practices, without understanding the monumental engineering that has gone into making those companies successful at scale. Monorepos, in my opinion, are an egregious example of this. The frank reality is that, at scale, how well an organization does with code sharing, collaboration, tight coupling, etc. is a direct result of engineering culture and leadership, and has nothing to do with whether a monorepo or a polyrepo is used. The two solutions end up looking identical to the developer. In the face of this, why use a monorepo in the first place? Please don’t!

[译]Redux作者从“UI工程要素”谈如何成为领域专家
https://mp.weixin.qq.com/s?__biz=MzU0Nzk1MTg5OA==&mid=2247484673&idx=1&sn=2056a95b60b9bc3b4739afc353564f7b
如果你开发过用户界面，那么你可能直接或使用库来处理以下这些挑战。 无论是哪种情况，我都鼓励你尝试不使用任何库的情况下，独立创建一个小应用，并不断重构，解决问题。 任何一个问题都没有通用的解决方案，在探索问题和不同的权衡尝试之中才能学到东西。

其实你并不懂 Unicode
https://zhuanlan.zhihu.com/c_185117725
古有 Babel 通天塔，今有 Unicode 字符集，很多编程语言支持 Unicode，甚至在语法层面直接支持，绝大部分程序员可能会因此觉得自己懂 Unicode 了，自己的代码不需要特别注意就能处理世界上所有语言的字符了，觉得 Unicode 高大上真善美，其实并非如此，下面讲述下作为一个程序员，你需要了解的几个关键概念，里面颇有几个大坑，看看各位知道几个。

The Chronicles of JavaScript Objects
https://blog.bitsrc.io/the-chronicles-of-javascript-objects-2d6b9205cd66
Objects are the foundation of JavaScript and permeate its every aspect. Almost everything in JavaScript is an object. In fact, only six things are not objects. They are — null,undefined, strings, numbers, boolean, and symbols. These are called primitive values or primitive types.

Artificial Intelligence in JavaScript with TensorFlow.js
https://www.javascriptjanuary.com/blog/artificial-intelligence-in-javascript-with-tensorflowjs
This is not an article about math (or maths as our European brethren like to call it) nor is it an exposition on the evils of a sentient AI that will kill us all in the end (I don’t subscribe to things of that sort), the goal, dear reader, is to take you down the well trodden path of what this is all about: the software engineering process and what it currently looks like for AI and JavaScript. 另附：Kalimdor.js: Machine Learning with TypeScript

Scaling Machine Learning Productivity at LinkedIn
https://engineering.linkedin.com/blog/2019/01/scaling-machine-learning-productivity-at-linkedin
The rate at which artificial intelligence (AI) knowledge is being disseminated and the rate of change in applied AI technologies show no signs of slowing down. Today’s software engineers are increasingly learning machine learning (ML) strategies as undergraduate students, and hardly a day goes by without the announcement of a new ML technique or framework. In this post, we’ll talk about our approach at LinkedIn to scaling AI and ML systems so that more engineers can take advantage of these techniques.

Adios to Winter Bash 2018
https://stackoverflow.blog/2019/01/04/adios-to-winter-bash-2018/
The 2018 Winter Bash festivities have come to an end. It was a fun season, especially with the addition of the sweater mini-game. As is our custom, we’ll recap a bit here on some of the stats for the hats as well as post some of the many outrageously attractive avatars we found across the network. This year we saw a 5-way tie for most hats earned during Winter Bash! However, the question still remains… did they earn all of the possible hats?

Start With a Website, Not a Mobile App
https://www.atrium.co/blog/founders-should-build-website-not-mobile-app/
This article helps young developers reframe their approach to ideation and iteration. As a student, indie hacker, or side-project hustler, it’s fun to experiment with new ideas and launch concept quickly. But, in my opinion, starting those projects on the web will be faster and more likely to succeed than starting with iOS or Android.

为什么有时候对产品钻研很深，却并没有带来好体验？
https://www.uisdc.com/the-curse-of-knowledge
你是否碰到过这样的情况：你做了大量的研究，然后制定了一个完美的策划，但是你的顶头上司却因为没有Get到其中的重点而放弃了整个策划？又或者，你对用户的需求和习惯做了很多调查和分析，结果在此基础上开发的功能，用户并没有按照你的计划去使用它？或者，你根据客户的需求设计了一个兼顾形式和隐喻的LOGO，可是客户仍然不喜欢它，仅仅因为客户没有看出其中包含的诸多含义？如果是，那么你就是遭遇了一种名为「知识诅咒」的认知偏见。

做会成功的设计
https://mp.weixin.qq.com/s/SUnXb0HJhS4owaPX2HR40A
新手设计师们有时会遇到这样一种情况：自己负责设计一两年的产品，突然面临产品方向调整或者业务解散的情况。而作为设计师，我们大多是非常敏感且感性的，当遇到自己投入心血、付出感情的产品，面临这样的情况，大多会灰心丧气、怀疑自己，“为什么自己付出了努力和心血，觉得十分满意的设计，无法获得市场的认可，好好的活下去？“ 本篇文章，希望能够帮助新手或者不是新手的设计师们，尽量避免遇到类似的情况，让自己付出心血的产品，更长远、更好的活下去。

Are Users Really Stupid?
https://uxplanet.org/are-users-really-stupid-92de6901e2be
As a designer I heard numerous times that users are stupid. They don’t understand obvious things, they don’t read the instruction and so on. I bet you heard or even said this phrase too. What’s wrong with it? While it’s at least offensive to users, it’s also not true. Let’s uncover why we say so and why users aren’t stupid at all.

Using Architectural History as a predictive model for the future of Product Design
https://uxdesign.cc/using-architectural-history-as-a-predictive-model-for-the-future-of-product-design-745b8848d77b
From the early 90s through the 2010s, the emerging need to make digital software accessible to the masses propelled software designers, penned “UX designers” by Don Norman, to explore and develop focused design patterns that were functional and simple. Through heavy reductionism, user journeys were made to be as streamlined as possible, and the sole purpose of the interface was to guide users onto the next step of the journey.

2018年底，快手的日活用户突破了1.6亿。在整个短视频行业监管趋严、竞争日益激烈的局面下，快手在前年底达到超级APP指标—1亿日活后 ，一年内再度增长6000万。在抖音被媒体舆论高度关注之外，快手仍在快速、稳健地狂奔。这似乎出乎了很多人意料。更出乎意料的是两个让业界感叹的数据。据信义资本的估计，得益于长尾用户的力量，快手直播付费率高达8%，为行业平均付费率4%的两倍；而在双11当天，快手主播散打哥一天卖货1.6亿元。这一事件，也被罗振宇在跨年演讲中归类到“难以察觉的小趋势”。另附：社交产品，「自我」难寻.

张一鸣的APP工厂
https://mp.weixin.qq.com/s/hbLLgw8Xe7NTpJSZaxcCUw 抖音是唯一，成为抖音的路径却不唯一。这家公司批量生产APP能力如此之强，而且历史成绩显示，核心产品成功的概率很大。除了这个 APP 工厂外，头条的人才机制是其成功的一个关键因素。
