直書書籍用 Calibre 轉 azw3 在 Kindle 上跑版的解決方法

圖為修正後範例。

有些直書書籍轉成 azw3 後排版會跑掉，在 Kindle 上僅剩翻頁變相反、從左到右的（因為原本是直書呀）。這裡是一些解決方法。

首先對要修正的書按右鍵選編輯，然後選 AZW3。

1. 直書變橫書

Demo: Coordinating async React with non-React views

tl;dr I built a demo illustrating what it might look like to add async rendering to Facebook's commenting interface, while ensuring it appears on the screen simultaneous to the server-rendered story.

A key benefit of async rendering is that large updates don't block the main thread; instead, the work is spread out and performed during idle periods using cooperative scheduling.

But once you make something async, you introduce the possibility that things may appear on the screen at separate times. Especially when you're dealing with multiple UI frameworks, as is often the case at Facebook.

How do we solve this with React?
