Why do we need PuppetJS versioning and Operational Transformations?

Optional Version control and JSON-Patch Transformations

Because of the asynchronous nature of bidirectional web communication (caused by network latency, server side push, etc), it can be assumed that client and the server are for most of the time out of sync.

In fact it is not necessarily client and server, all following applies as well to server-server, client-client, or any peer-to-peer collaborating on JSON document.

To improve mutual view-model consistency, we introduce optional features:

1. Versioning,
2. Operational Transformations.

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

Strictly Frameworks

• Mobiledoc - github.com/bustle/mobiledoc-kit - framework to build editors with a standardized JSON structure
• ShareDB - github.com/share/sharedb - framework to sync any JSON document using operational transforms, add real-time collaborative editing to anything else
• Bangle.dev - github.com/bangle-io/bangle.dev - toolkit built for building editors, based on prosemirror

Abstracted Editors

These use separate document structures instead of HTML, some are more modular libraries than full editors

Smart Caps Lock: Remap to Control AND Escape (Linux, Mac, Windows)

把 Caps Lock 變成智慧的 Control 以及 Escape ：

• 單獨輕按一下就是 Escape 。
• 若按下時同時按著其他鍵，就會是 Control 。

這應該是 Vim 和 Emacs 的最佳解了！(Emacs? Bash 的快捷鍵就是 Emacs 系列的)

• Send Escape if you tap Caps Lock alone.
