I wanted a simple stock portfolio monitoring tool. I failed to find a simple and free app, but happily discovered that Google Sheets does what I need perfectly!
About a month ago, I discovered Apple had imposed new limitations on the free Apple Developer account. This limits the period that an app can run on your phone to 7 days (due to Provisioning Profiles) and the number of changes you can make to the project (not the source code, but Capabilities like App Groups).
Apps, even after being removed from the Launchpad or Applications sidebar in Finder, do leave preferences and other files scattered around. Where are they, typically, and how does one find them?
I discovered that Xcode includes a diff tool called FileMerge. Where is it and how do you launch it?
I, like many other iPhone users, turn on AssistiveTouch so that I don't have to press the Home button. Historically, this button has been quick to fail, so using the on-screen icon will save some wear-and-tear. And with iOS 9, AssitiveTouch has become customizable! Shocking (for Apple, not much is customizable)!
To clean install Windows 10, you need more than the product key from an upgraded instance of Windows 7/8. You'll need a file called
tokens.dat created during the upgrade process.
Forget the complex or manual steps, or costly tools to get screen shots scaled down from a retina display. I have a shell script that triggers an interactive window screen capture, saves the screen shot (assumed to be 2x retina display), re-sizes it to 1x and compresses the PNG further! Best of all, it does not require paid software or Automator.
Some tweaks to my OS X shell (Terminal.app) that I've found useful.
Apache and PHP 5.5.27 are installed already in OS X 10.11 El Capitan, so just a little enabling is required.
Updated 12 Oct 2016: See the slightly updated guide for macOS 10.12 Sierra, which has been updated to Apache 2.4.23 and PHP 5.6.24.
