How to hide <select> dropdown's arrow in Firefox when using "-moz-appearance: none;".

This is no longer a bug. I'm keeping the gist for historical reasons, as it helped to get it fixed. Make sure to read the notes by the end of the post.

How to remove hide the select arrow in Firefox using -moz-appearance:none;

TL;DR (or, the fix)

  1. Set -moz-appearance to none. This will "reset" the styling of the element;
  2. Set text-indent to 0.01px. This will "push" the text a tiny bit[1] to the right;

So, you want to run Chrome headless.

Update May 2017

Eric Bidelman has documented some of the common workflows possible with headless Chrome over in https://developers.google.com/web/updates/2017/04/headless-chrome.

Update

If you're looking at this in 2016 and beyond, I strongly recommend investigating real headless Chrome: https://chromium.googlesource.com/chromium/src/+/lkgr/headless/README.md

Windows and Mac users might find using Justin Ribeiro's Docker setup useful here while full support for these platforms is being worked out.

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:
