I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Gibberfish

Generate test video content with Node.js. Useful for subtitle synchronisation testing. Gibberfish utilises the say command, GraphicsMagick and ffmpeg.

Content is generated by creating multiple concurrent segments before concatenating them so the generation time is significantly shorter than the output running time.

The output is a ~10 minute video with H.264 video, AAC audio and separate SRT and VTT subtitle files. The subtitles match the synchronized displayed text and spoken (TTS) audio tracks.

Sample Output (YouTube)

Requirements

Gibberfish requires:

macOS with say
Node 6+
GraphicsMagick
ffmpeg (providing the ffmpeg and ffprobe commands)

Usage

npm install -g gibberfish
