IaaS指提供系统（可以自己选）或者储存空间之类的硬件，软件要自己手动装；PaaS提供语言环境和框架（可以自己选）；SaaS只能使用开发好的软件（卖软件本身）；BaaS一般类似于非关系数据库，但各家不通用，有时还有一些其它东西。

Javascript request yak shave

I wanted to easily make HTTP requests (both GET & POST) with a simple interface that returns promises.

The popular request & request-promises package are good, but I wanted to figure out how to do it w/out using external dependencies.

The key features are:

the ability to set a timeout
non-200 responses are considered errors that reject the promise.
any errors at the TCP socker/DNS level reject the promise.

Navigating the modes of Vim

This diagram illustrates navigating through Vim’s modes. It was built factoring Vim 9 (i.e., all its modes, including up to two new modes, cr and cvr, in November 2023). Information about the state() and 'showmode' is provided too.

SVG version

Some features are only available in the SVG version. It is not provided directly from within this gist’s files because SVGs do not always play nicely in GitHub (particularly, refusing to display embedded fonts).

The SVG version includes hover text help, which shows pertinent information about the underlying key, command, mode, etc.

This procedure was tested on FreeBSD-CURRENT build from d8819d88af52.
