Making Bookmarklets

I'm feeling very clever. I've got this sweet line of javascript that replaces "cloud" with "butt". My mom would LOVE this, but she doesn't computer very well. I'm afraid to show her the Developer Console and have her type/paste this in. But she IS pretty good at bookmarks, she knows just how to click those!

A bookmark normally takes you to a new web page. A bookmarklet is a bookmark that runs javascript on the current page instead of taking you to a new page. To declare that it is a bookmarklet, the "location" it points to starts with javascript:.

From Fabrice Bellard, with minor name change (umulh):

// return the high 32 bit part of the 64 bit addition of (hi0, lo0) and (hi1, lo1)
Math.iaddh(lo0, hi0, lo1, hi1)

// return the high 32 bit part of the 64 bit subtraction of (hi0, lo0) and (hi1, lo1)
Math.isubh(lo0, hi0, lo1, hi1)

// return the high 32 bit part of the signed 64 bit product of the 32 bit numbers a and b

##what are generators##

They're pausable functions, pausable iterable functions, to be more precise
They're defined with the *
every time you yield a value, the function pauses until .next(modifiedYieldValue) is called

var myGen = function*() {
  var one = yield 1;
  var two = yield 2;
  var three = yield 3;
 console.log(one, two, three);

Running Node on a Samsung 303C Chromebook

Motivation

After @mikeal and @lyle purchased Chromebooks for kids activities at NodeConf 2014, I was very impressed with the device and decided to explore this as a laptop and hacking device for my kids (7 & 8). I'd love to retain the simplicity of the web-focused ChromeOS experience while letting my kids hack on NodeBots and learn how to program.

It seems like the platforms that ChromeOS runs on are quite diverse. The Samsung 303C hit the right balance of being an aesthetically pleasing looking device, having respectable build quality and the amazing $250 price point. The 303C has an ARM processor. Not all Chromebooks do. I'm writing the below step-by-step very specifically for this system.

Resources

Intro

The plan is to create a pair of executables (ngrok and ngrokd) that are connected with a self-signed SSL cert. Since the client and server executables are paired, you won't be able to use any other ngrok to connect to this ngrokd, and vice versa.

DNS

Add two DNS records: one for the base domain and one for the wildcard domain. For example, if your base domain is domain.com, you'll need a record for that and for *.domain.com.
