First the simplest/core layers, then optional layers depending on which features/functionality you want.

How I Created HTTP Prompt and Got 5000+ Stars on GitHub

Two months ago, I published an open source project, which went viral by gaining 1200+ stars in the first 24 hours. As of this writing, it has attracted 5000+ stars. The project is called HTTP Prompt:

https://github.com/eliangcs/http-prompt

Here I want to share its development story.

It all began with Vertica. Not long ago, I used Vertica every day for my work. Vertica is a powerful database, but the official client (vsql) is not powerful at all. The GUI alternative, DbVisualizer, is bad as well.

GitHub Markdown Theme for Visual Studio Code

This CSS stylesheet allows you to preview markdown files in VSCode using GitHub's mardown theme. This CSS was taken directly from the official GitHub Markdown repo. I replaced their top-level .markdown-body class with the body tag so it would work in VSCode, and added styling for the html tag to match GitHub's fixed-width container.

Instructions

1. Copy the CSS file to your computer
   Copy the github-markdown.css file below to your computer. You can put it anywhere you want, but I chose to put it in the same folder as my VSCode settings file.

2. Edit your VSCode settings
   If you want to use this theme for all of your projects, then edit your User Settings file. If you just want to use this them
