A strong frame for functional programming in Java

Regarding functional programming in Java, the most important design rule is to avoid mutability. We use it only in places, where it makes sense and we use it internally, only, i.e. mutability does not leak to the outside as public API. Within the last years I deduced these three simple rules to achieve it:

Preamble

i. Don't try to create purely functional programs with Java. Simply spoken, Java is not the right language for that.

ii. It is most important to follow these rules consistently and make no exceptions other than stated.

Optimize non-Apple SSDs on OS X. (Run the following commands in the terminal.)

Enable TRIM support

Check IOAHCIBlockStorage version:

open /System/Library/Extensions/IOAHCIFamily.kext/Contents/PlugIns/IOAHCIBlockStorage.kext/Contents/version.plist

Enable TRIM on non-Apple SSDs in OS X 10.8.2 Mountain Lion.

WARNING: This is ONLY tested on 10.8.2 (IOAHCIBlockStorage version 2.3.1), and NOT earlier or later versions. 

Check /System/Library/Extensions/IOAHCIFamily.kext/Contents/PlugIns/IOAHCIBlockStorage.kext/Contents/version.plist 

Technical note: The driver changed in 10.8.2 and similar perl commands that worked in earlier OS X versions did not work for me once I updated to 10.8.2.

Run the following commands in Terminal…

# UPDATE for 10.10.4+: please consider this patch obsolete, as apple provides a tool called "trimforce" to enable trim support for 3rd party SSDs
# just run "sudo trimforce enable" to activate the trim support from now on!
