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 = [email protected]: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:

Shell script to set up a GitHub Project's Issues' Labels as described in <http://rentzsch.tumblr.com/post/252878320/my-lighthouse-ticket-settings-with-colors>. WARNING: script assumes a newish project that hasn't really used labels yet. It deletes all default labels, which means DATA LOSS if you've used them for anything.

Profiling an application in Mac OS X

Profiling an application in Mac OS X

Finding which process to profile

If your system is running slowly, perhaps a process is using too much CPU time and won't let other processes run smoothly. To find out which processes are taking up a lot of CPU time, you can use Apple's Activity Monitor.

The CPU pane shows how processes are affecting CPU (processor) activity:

import UIKit
import XCPlayground
XCPlaygroundPage.currentPage.needsIndefiniteExecution = true
func perform(initial: Int) {
var value: Int = initial
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, 1), dispatch_get_main_queue()) { [myConstant = value] in
print("constant in first block \(myConstant)")
print("captured \(value)")
value = initial * 2

New stuff from WWDC 2016

Following the tradition from last year, here's my complete list of all interesting features and updates I could find in Apple's OSes, SDKs and developer tools that were announced at this year's WWDC. This is based on the keynotes, the "What's New In ..." presentations and some others, Apple's release notes, and blog posts and tweets that I came across in the last few weeks.

If for some reason you haven't watched the talks yet, I really recommend watching at least the "State of the Union" and the "What's New In" intros for the platforms you're interested in. The unofficial WWDC Mac app is great way to download the videos and keep track of what you've already watched.

If you're interested, here are my WWDC 2015 notes (might be useful if you're planning to drop support for iOS 8 now and start using some iOS 9 APIs).


OSX → macOS 10.12 Sierra
