WaterfallProcess
https://martinfowler.com/bliki/WaterfallProcess.html
In the software world, “waterfall” is commonly used to describe a style of software process, one that contrasts with the ideas of iterative, or agile styles. Like many well-known terms in software it’s meaning is ill-defined and origins are obscure - but I find its essential theme is breaking down a large effort into phases based on activity.

Build your own React
https://pomb.us/build-your-own-react/
We are going to rewrite React from scratch. Step by step. Following the architecture from the real React code but without all the optimizations and non-essential features. If you’ve read any of my previous “build your own React” posts, the difference is that this post is based on React 16.8, so we can now use hooks and drop all the code related to classes.

How Discord achieves native iOS performance with React Native
https://blog.discordapp.com/how-discord-achieves-native-ios-performance-with-react-native-390c84dcd502
We knew that our app was once fast, and we wanted to more deeply understand if the problems we were seeing could be tackled on our end, or if the issue was more deeply rooted in React Native itself. With this in mind, we created a mobile performance squad, whose mission was to execute a deep dive into driving top tier performance on across all supported iOS devices. We would like to share what we have learned! 另附:Microsoft looks to React Native as a way to tackle the cross-platform development puzzle.

Semantic sidenotes for the web
https://www.kooslooijesteijn.net/blog/semantic-sidenotes
On this website, sidenotes appear next to the article when there’s enough space. On small screens, they’re hidden by default and can be made visible with a tap. The problem is, it’s hard to find a properly semantic HTML solution to do this.

instant.page 3.0 — incorporating the best from quicklink
https://instant.page/v3
instant.page makes your site’s pages instant — in 1 minute of effort — by preloading pages right before a user clicks on them: when they hover over a link for 65 ms; there’s one chance out of two that they will click then. On mobile, it preloads when they start touching their display, before releasing it.

Why is the Migration to Python 3 Taking So Long?
https://stackoverflow.blog/2019/11/14/why-is-the-migration-to-python-3-taking-so-long/
In Pycon in 2014, Guido van Rossum, the creator of Python and, at the time, the Benevolent Dictator For Life of the language, stood on stage in a shirt that had a large 2.8 written on it in block letters, with a big red no entry sign through it. “It’s time to move on to Python 3,” he said, telling the audience that they should start adopting the new version of the language into their workflows. 另附:My Python Development Environment, 2020 Edition.

https://microsoft.github.io/chart-parts/
The vision of chart-parts is to implement a grammar of graphics in JavaScript in a flexible, architecture-agnostic way while dovetailing nicely with frameworks application developers use such as React. To date, implementations of the Grammar of Graphics have tended to exist as closed systems. While a closed system can be useful for certain categories of users, we believe that these systems should provide escape hatches and flexibility.

Web Animation In The Post-Flash Era

HTML5, CSS3, JavaScript, and SVG (scalable graphics) seem to be the best solutions for web animation. Using these modern web technologies and languages will help tackle most, but not all, of the above problems. But it’s always a good idea to tread carefully, especially when in uncharted territory, and extensive QA and testing is a must.
