Apple, 陰陽, and the Power of Love

Yin Yang: it's become the single most ubiquitous secret code symbol of Apple Inc. It's everywhere. It's in their 'universal' logo. And it's in more and more icons. And it's in toolbar buttons as well. In combo boxes. In push buttons. In scroll bar thumbs and arrows. In table view and outline view headers. In the menu bar. It's bloody everywhere. Maybe it all started back with Safari. That's years ago. Safari came out with an entirely new look not integrated into the environment. Everything was hot wired. Especially the toolbar was new. This was not standard NeXTSTEP NSToolbar. NSToolbar is lugubrious enough but this was more so. Nothing is automated - everything requires code of its own, used one time only, in an environment that prides itself on code and object reuse. Here's the Tiger NSToolbar header file. It's copyrighted and last updated three years ago.

Safari

There are 138 TIFFs in Safari.app/Contents/Resources for a total of 165472 bytes. Effectively 596 KB because of clustering. Each of those 138 images has to be loaded separately. Ask for the image; find it on disk; wait for the disk to spin into position; whisk it up. On to the next one. All 138 of them. Just to load the bloody program. And Safari still loads pretty fast. Not as fast as it used to but still pretty fast. And it's a native application as opposed to Firefox - it's supposed to be faster. Leaner. Meaner.

Safari's Tiger image is just over 2 MB. Meaning about 1 MB per CPU architecture. Meaning all things considered the poor program struggles longer and harder to load its bloody toolbar and other images than it does loading its executable code.

[This because the greatest arbiter is not file size but the median access time. You count the cylinders - not the clusters. Ed.]

Apple Mail

Amongst standard system apps Safari is but a pretender to the throne - Apple Mail is the undisputed queen. There are 274 TIFFs in Mail.app/Contents/Resources for a total of 482836 bytes. Effectively 1.4 MB because of clustering. Each of those 274 images has to be loaded separately. Ask for the image; find it on disk; wait for the disk to spin into position; whisk it up. On to the next one. All 274 of them. Just to load the bloody program. And this isn't counting all the other resources that have to be loaded. Still wondering why it takes a fortnight to load Apple Mail?

Mail's Tiger image is approximately 2 MB per architecture. Meaning all things considered it too works harder and longer to load its bloody toolbar and other images than it does loading its executable code.

In All Honesty

In all honesty these hundreds (thousands) of images don't all have to be loaded at runtime - the code might play it clever with 'lazy load' and only get them when they're needed. But they still have to be loaded sooner or later - and most of them have lots of Yin Yang in them. Woo-hoo.

Code vs Data

Code is always better than data. That's why there are things like toolbar engines. All a toolbar engine needs is one glyph per button - the code takes care of the rest. Programmatically creating the disabled, pressed, checked, and other images on the fly.

In fact it probably takes as much or more code - and certainly more time - to calculate the name of the file needed and load it as it does to just let a toolbar engine do its thing. Which is why it's never good to keep things outside the system: if it's a good idea then integrate it. But this Yin Yang thing is now five years old.
