Example of how a simple OWL ontology / RDFS vocabulary could be defined with JSON-LD, defining the meaning of properties and classes. The second file shows the RDF triples of the vocabulary by using the JSON-LD sandbox. As a visualization - see http://www.essepuntato.it/lode/owlapi/https://gist.github.com/stain/7690362/raw/114f836a64291a3f894c44…

git utility to move/rename file or folder and retain history with it.
#!/bin/bash
#
# git-mv-with-history -- move/rename file or folder, with history.
#
# Moving a file in git doesn't track history, so the purpose of this
# utility is best explained from the kernel wiki:
#
# Git has a rename command git mv, but that is just for convenience.
# The effect is indistinguishable from removing the file and adding another
# with different name and the same content.

Post explaining why objects often use less memory than arrays (in PHP)

Why objects (usually) use less memory than arrays in PHP

This is just a small post in response to [this tweet][tweet] by Julien Pauli (who by the way is the release manager for PHP 5.5). In the tweet he claims that objects use more memory than arrays in PHP. Even though it can be like that, it's not true in most cases. (Note: This only applies to PHP 5.4 or newer.)

The reason why it's easy to assume that objects are larger than arrays is because objects can be seen as an array of properties and a bit of additional information (like the class it belongs to). And as array + additional info > array it obviously follows that objects are larger. The thing is that in most cases PHP can optimize the array part of it away. So how does that work?

The key here is that objects usually have a predefined set of keys, whereas arrays don't:
