These aren’t all dependencies, but only the ones which isn’t loaded by my usual init-file.

Dependency Injection in Functional Programming

There exist several DI frameworks / libraries in the Scala ecosystem. But the more functional code you write the more you'll realize there's no need to use any of them.

A few of the most claimed benefits are the following:

• Dependency Injection.
• Life cycle management.
• Dependency graph rewriting.

# Why?
# To paste text into windows that normally don't allow it or have access to the clipboard.
# Examples: Virtual machines that do not yet have tools installed, websites that hijack paste
#
# Extended vs Simple?
# * Includes an initial delay to allow you to change active windows
# * Adds small delay between keypresses for slower responding windows like SSH sessions
# * Better handling of numbers
# * VMWare bug fix

If you want to learn Scala, I’d suggest:

• Install IntelliJ + Scala Plugin
• Don’t do the Coursera courses yet.
• Don’t do the “red book” Functional Programming in Scala yet.
• Do: http://underscore.io/books/
  • Essential Scala
  • Essential Play
  • Essential Slick
• Do Scala for the Impatient: https://www.amazon.com/Scala-Impatient-Cay-S-Horstmann/dp/0321774094

Available Public Wildcard DNS Domains pointing to localhost (127.0.0.1)

The best way to safely and securely use local domains pointing to 127.0.0.1 is to edit your local settings (/etc/hosts) and add your own settings. Keep in mind if you want to use subdomains, you need to enter all variations.

Example:

# Adding bottom of your current file /etc/hosts
################# MY LOCAL DOMAINS
127.0.0.1 local.com admin.local.com
127.0.0.1 domain1.com
