Image Blurring – Accelerate vs. CoreImage

1.3MB png 640x1136

  • Accelerate 179ms every time
  • CoreImage 298ms first time 147ms subsequent times @1x scale
  • CoreImage 262ms first time 126ms subsequent times @0.5x scale
  • CoreImage 260ms first time 118ms subsequent times @0.25x scale

(Lower on 0.5x probably because of whole number for blur radius)

O'Reilly Git Webinar

The Fringes of Git

Overview

Matthew McCullough and Tim Berglund, authors of the O'Reilly Git Master Class videos will introduce you to the very edges of Git's capabilities. There are plenty of "Getting Started with Git" sessions on the web, but we'd like to take 40 minutes of your time in an entirely different direction. These 40 minutes will primarily be live coding with a few diagrams for reference. We'll show you how Git reaches farther than any other version control system to provide capabilities for both the novice and the master craftsperson.

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).

Declare on your main init that all other init methods should call. It's a nice additional semantic warning. Works with Xcode 5.1 and above. Not tested with earlier variants, but should just be ignored. A reference to this macro shortly appeared in https://developer.apple.com/library/ios/releasenotes/ObjectiveC/ModernizationObjC/AdoptingModernObj…

/**
Provides the ability to verify key paths at compile time.
If "keyPath" does not exist, a compile-time error will be generated.
Example:
// Verifies "isFinished" exists on "operation".
NSString *key = SQKeyPath(operation, isFinished);
// Verifies "isFinished" exists on self.

Some useful Git aliases that I use every day
#
# Working with branches
#
# Get the current branch name (not so useful in itself, but used in
# other aliases)
branch-name = "!git rev-parse --abbrev-ref HEAD"
# Push the current branch to the remote "origin", and set it to track
# the upstream branch
publish = "!git push -u origin $(git branch-name)"
