RESP3 specification

Versions history:

• 1.0, 2 May 2018, Initial draft to get community feedbacks.

Background

The Redis protocol has served us well in the past years, showing that, if carefully designed, a simple human readable protocol is not the bottleneck in the client server communication, and that the simplicity of the design is a major advantage in creating a healthy client libraries ecosystem.

Yet the Redis experience has shown that after about six years from its introduction (when it replaced the initial Redis protocol), the current RESP protocol could be improved, especially in order to make client implementations simpler and to support new features.

So, you might be asking yourself, what is GistLog?

GistLog is a blogging "platform" for people who want to quickly write and publish content, in Markdown, and don't want to bother with yet another platform and yet another login and yet another group hoarding their content. With GistLog, you use your pre-existing GitHub login, you store the data in your own GitHub account, and you can publish with a single click.

Using GistLog

1. Create a public gist with a single file using Markdown. Set the gist description to be the title of your blog post
2. Copy the gist URL, and paste it into the text box on the GistLog create page
3. Copy your resulting URL and share it as your blog post—note that it will be in the form of https://gistlog.co/your-github-username/gist-id
4. If you want to have your own GistLog landing page (e.g. gistlog.co/mattstauffer), [read all about it](https://gistlog.co/mattstauffer/a82db5

Setting up a SSL Cert from Comodo

I use Namecheap.com as a registrar, and they resale SSL Certs from a number of other companies, including Comodo.

These are the steps I went through to set up an SSL cert.
