why css purists will love glam

I made a little styling lib called glam

(some features are in development)

one

let's start off with the simplest use case. we'll make an 'index.html' page, and assume we've setup our js bundler to output bundle.js

list of things that don't do what they say they do

(also know as lies and/or alternative facts)

js

  • setImmediate - doesn't set anything immediately, waits for a tick before executing
  • setTimeout(fn, n) - never sets the timeout to exactly n
  • Math.random() - computers cannot generate random numbers
  • Promise - is a lie when rejected
  • Array.reduce - accumulates, does not reduce (via @sbmadhav)

ServiceWorker for github pages.

ServiceWorker for github pages

This is a ServiceWorker template to turn small github pages into offline ready app.

Why ?

Whenever I make small tools & toys, I create github repo and make a demo page using github pages (like this one).
Often these "apps" are just an index.html file with all the nessesary CSS and JavaScript in it (or maybe 2-3 html/css/js files). I wanted to cache these files so that I can access my tools offline as well.

Notes

Make sure your github pages have HTTPS enforced, you can check Settings > GitHub Pages > Enforce HTTPS of your repository.

Running CouchApps on PouchDB in the browser using service workers - without any modifications!

Running CouchApps on PouchDB in the browser using service workers

What is this?

A description of how to run an existing CouchApp on PouchDB in the browser using service workers - without any modifications to existing code being necessary! The best thing is that if service workers aren't available, the CouchApp will still run as normal: that is, online.

Demo

Oauth2 Explanation

OAUTH2

The Problem

I’m a web app that wants to allow other web apps access to my users’ information, but I want to ensure that the user says it’s ok.

The Solution

I can’t trust the other web apps, so I must interact with my users directly. I’ll let them know that the other app is trying to get their info, and ask whether they want to grant that permission. Oauth defines a way to initiate that permission verification from the other app’s site so that the user experience is smooth. If the user grants permission, I issue an AuthToken to the other app which it can use to make requests for that user's info.

Note on encryption

Oauth2 has nothing to do with encryption -- it relies upon SSL to keep things (like the client app’s shared_secret) secure.

Checkout github pull requests locally

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:
