Optimize Toolset

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.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Demo of Math Magic

Every time you shuffle a deck of cards well, smoosh it for a few minutes or riffle it seven or more times, chances are you have put those playing cards into an order that they have never been in in the entire history of cards, or humans, or the universe. Seriously. -- Michael Stevens

When the program starts, it will continuously and randomly reorder a deck of cards, remembering each order it produces. When an order has appeared more than once, it stops. This program demonstrates how long it would take to achieve two identical deck orders through random shuffling. In fact, the program will start to take a significant amount of time even if there are only 12 cards. So if you select 13 cards, chances are your program is going to freeze for a while. 13! (13 factorial) is already QUITE BIG!!
