How to get the current selected Xcode and list installed

Current Selected Xcode

`xcode-select`

This is the most common way to get the path to the selected instance:

xcrun xcode-select --print-path

I use PlantUML a lot. It's what I use for drawing all sorts of diagrams and it's handy because of its easy markup (once you get used to it) while making things easy to maintain as projects grow (thanks to version control)

This gist explains how I do my PlantUML workspace in a project.

The idea is to keep a globals directory for all diagrams to follow (like the "stylesheet" below) to keep things consistent.
I use a stylesheet.iuml file that keeps the use of colors consistent through use of basic FOREGROUND, BACKGROUND and ACCENT colors.
The style-presets.iuml file defines these colors so you can make "presets" or "themes" out of them.
As stated in the stylesheet.iuml, you'll need the Roboto Condensed and Inconsolata fonts for these to work properly.
You can choose to either run the PlantUML jar over your file/s, or use an IDE like VSCode with the PlantUML extension. Here's a preview of example-sequence.puml for example: https://imgur.com/Klk3w2F

type below:

brew update
brew install redis

To have launchd start redis now and restart at login:

brew services start redis

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

How to Change Open Files Limit on OS X and macOS

This text is the section about OS X Yosemite (which also works for macOS Sierra) from https://docs.basho.com/riak/kv/2.1.4/using/performance/open-files-limit/#mac-os-x

The last time i visited this link it was dead (403), so I cloned it here from the latest snapshot in Archive.org's Wayback Machine https://web.archive.org/web/20170523131633/https://docs.basho.com/riak/kv/2.1.4/using/performance/open-files-limit/

	/// We modify Google Firebase (and eventually Analytics) to load the mac-specific plist at runtime.
	/// Google enforces that we have a file named "GoogleService-Info.plist" in the app resources.
	/// This is unfortunate since we need two different files based on iOS and Mac version
	/// One solution is a custom build step that copies in the correct file:
	/// https://stackoverflow.com/questions/37615405/use-different-googleservice-info-plist-for-different-build-schemes
	/// However, this is basically impossible since Catalyst doesn't set any custom build variables, so detection is extremely difficult.
	/// We swizzle to modify the loading times.
