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 🙏

redistribute values - equally, by default

(optionally, set a custom distribution, or set a level of acceptable error)

example

let redistribute = require('bernie')

// given some distribution of values
let unequal = {
  one: 0.9,
  two: 0.3,
  three: 0.7,
}

// produce steps that would 
// redistribute those values 
// equally among entities
redistribute(unequal)
// [ { from: 'one', to: 'two', amount: 0.2666666666666667 },
//   { from: 'three', to: 'two', amount: 0.0666666666666666 } ]

optionally, we can produce steps to achieve some arbitrary distribution of values.

// some values
var unequal = {
  one: 0.9,
  two: 0.3,
  three: 0.7,
}

// some optimal distribution 
// of those values
var dist = {
  one: 0.99,
  two: 0.01,
  three: 0.01,
}

var steps = redistribute(unequal, { distribution: dist })

steps
// [ { from: 'two', to: 'one', amount: 0.28099999999999997 },
//   { from: 'three', to: 'one', amount: 0.6809999999999999 } ]

in both of these examples, we can apply these steps to unequal to produce the resulting values.

steps.map(step => {
  unequal[step.to] += step.amount
  unequal[step.from] -= step.amount
})

unequal
// { one: 1.862,
//   two: 0.019000000000000017,
//   three: 0.019000000000000017 }

install

npm i bernie

api

redistribute(unequalDistribution, opts)

returns steps needed to redistribute unequalDistribution.

opts.distribution is an object where the keys are the same as keys in unequalDistribution, and the values are proportions, representing the ideal distribution of values after steps are applied. by default, all values will be distributed equally.

opts.error is an amount of acceptable error, in the unit of values represented in unequalDistribution.
