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:
| function* asyncIterator() { | |
| let value, done; | |
| while ({value, done} = (yield null), !done) { | |
| console.log("got", value); | |
| } | |
| console.log("done"); | |
| } | |
| it = asyncIterator(); | |
| it.next(); |
This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.
The script is here:
#!/bin/bash
convert "$1" -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 "$2"

The reflow appens as many times as there are frames per seconds. It recalculate all positions that change in order to diplay them. Basically, when you scroll you execute a function where you move things between two reflows. But there are functions that triggers reflows such as jQuery offset, scroll... So there are two things to take care about when you dynamically change objects in javascript to avoid too many reflows:

This started from a chat in the [https://gitter.im/rwaldron/johnny-five](Johnny Five Gitter) and I thought I'd put some notes together because this comes up relatively often as people run into the terminology confusion that is caused by the Servo Manufacturers adopting the term PWM and it's usage amongst the Arduino community in relation to analogWrite().
This is my attempt at an explanation so if I've made any mistakes then please PR and we can make this better for everyone.
Servo is generally served by PWM support, right?
Sort of - PWM is typically a reference to an on/off duty cycle time - if I set my duty cycle to 50% then my pulses are on for 50% of the time and off for 50% of the time. If it's 10% then it's on 10% of the time, off 90%.
