Notes on Apple’s Under-Documented LaunchD

Start triggers fire regardless of other conditions

For example, StartOnMount=true will cause the job to start when anything is mounted even if other conditions, e.g. QueueDirectories, say the job should not run

Rhythm of repeating jobs

The StartInterval timer begins ticking at the moment the plist is loaded. If something like QueueDirectories is preventing the job from

Amphetamine

Simple toggleable menubar replacement for Caffeine in Hammerspoon, utilizing ASCIImage (for vector) to create the amphetamine icons. Motivated by the official Caffeine app's icon looking bad on Retina

Get latest version here: amphetamine.lua

Save as amphetamine.lua in ~/.hammerspoon/ and put amphetamine = require "amphetamine" in your init.lua

It is possible to have multiple versions of Xcode on your Mac. Where you may have trouble is getting your command-line to work well. Various develper tools are in the developer directory. When there are multiple versions of Xcode on a Mac one of them should be selected.

Print Path

Printing the path for the developer directory will show which copy of Xcode is currently selected.

Introduction

This is about documenting getting Linux running on the late 2016 and mid 2017 MPB's; the focus is mostly on the MacBookPro13,3 and MacBookPro14,3 (15inch models), but I try to make it relevant and provide information for MacBookPro13,1, MacBookPro13,2, MacBookPro14,1, and MacBookPro14,2 (13inch models) too. I'm currently using Fedora 27, but most the things should be valid for other recent distros even if the details differ. The kernel version is 4.14.x (after latest update).

The state of linux on the MBP (with particular focus on MacBookPro13,2) is also being tracked on https://github.com/Dunedan/mbp-2016-linux . And for Ubuntu users there are a couple tutorials (here and here) focused on that distro and the MacBook.

Note: For those who have followed these instructions ealier, and in particular for those who have had problems with the custom DSDT, modifying the DSDT is not necessary anymore - se

Async/Await for Swift

Proposal: SE-XXXX
Authors: Chris Lattner, Joe Groff

Introduction

Modern Cocoa development involves a lot of asynchronous programming using closures and completion handlers, but these APIs are hard to use. This gets particularly problematic when many asynchronous operations are used, error handling is required, or control flow between asynchronous calls gets complicated. This proposal describes a language extension to make this a lot more natural and less error prone.

This paper introduces a first class Coroutine model to Swift. Functions can opt into to being async, allowing the programmer to compose complex logic involving asynchronous operations, leaving the compiler in charge of producing the necessary closures and state machines to implement that logic.
