Apple's implementation of Objective-C also offers vtable dispatching as an optimization since Mac OS X 10.6, and benchmarks indicate little chance that either approach gives you much improvement on modern hardware.

(Don't mean to keep posting but I did some more reading this morning and I found it interesting.)

I'm running Safari 4 on an Intel imac but I have 3.2.1 loaded via Multi-Safari. I run Safari 3 on an PPC G4 notebook since Safari 4 seemed to kill its battery and performance. I can't stand how slow Firefox seems on the same machines but I've only found Safari 4 will use up all the CPUs for no good reason. I would love have a symbol added to the "Window" menu options that told me which windows were eating up all the ram/cpu since I'll frequently have 20 to 30 windows open.

Or just download it from here - the guy has bundled the proper version of WebKit inside the application. If you haven't done that (I'm not aware of how Pacifist works) you're actually just using the new version of WebKit inside the old application. http://michelf.com/projects/multi-safari/

Furthermore, wouldn't Apple want developers to keep a copy of Safari 3 around for compatibility testing, even after Safari 4 goes out of beta? Yeah, I know that you can only have one official Webkit install that the rest of the system uses, but there is nothing preventing Apple from providing a standalone version of the the beta, or repackaging Safari 3 to be standalone when you install the Safari 4.

Anyway, Michel Fortin was nice enough to do that for all the major stable releases of Safari. Enjoy.

You want Megazoomer. I also pair it up with Blacklight for light-on-dark text.

Tried inverting the default colors in Firefox a while back - black background, white text, dark skins, etc. I wanted to reduce the strain on my eyes from reading the screen with the room lights off. I was somewhat successful - with certain sites. Other sites didn't respond well to my browser alterations, and I eventually gave up. If that computer was a mac I'd've tried Black Light, but, alas...

Black backgrounds are easier to read - white backgrounds emit a lot of photons, whereas black backgrounds with white/gray/yellow text emit photons at a rate orders of magnitude lower.

I like reading the about page on Blackle.com - except for the light grey bars above and below make it a strain. Perhaps I should find that black skin again...

Yes. Virtualisation is the best solution to this problem. Remember Internet Exploder is tied to Windows so you can only have one version of it installed at a time. Being able to run multiple copies of Windows each with it's own version of IE is very useful.

If you want to run multiple versions of Safari on Mac OS look here: http://www.michelf.com/projects/multi-safari/
There is hosted self-contained builds of Safari using all the released variants of the rendering engine. Credit to Michel Fortin for doing this.

I believe you are mistaken in your analys.

It doesn't mean it "sounds simular to psychology 101" it is what you think to read. It's just flattering you praise my ability to recognise psychological patterns and making an analogy as accurate it makes you suspect I speak out of experience or am writing from my subcontious.

There was no personal information in my post, but mostly it seems most slashdotters seem to relate best to "highschool dynamics" and analogies relating to that. I do not speak in terms of "smarter", "the whole school", cause I haven't been there in quite a while. I don't mirror myself to my "popularity" to define myself or to place myself into society (nor my intelligence, nor my education, nor my possesions).

As a matter of fact when you get into the "real world" (I'm assuming you're a highschool kid) popularity matters not. The results you deliver matter, your actions and how you take care of your family and people who have value in your life and not how "cool" people think you are.

You don't have to agree persé, people disagree, not everyone thinks the same. Doesn't mean the other has "unresolved social issues" when one doesn't share your views or misses the motivation of certain comments which imply IE-usage is down and decling. Exact percentages are impossible to show. Cause ofcourse windowsupdate will have a near 100% usage IE browsers.

Now, you say "You cannot neglect 80%" (as that seems to be your point). You cannot neglect that 20% goes out to actively download a browser when one is installed in the OS already, which caused IE to win the browserwars. In my view Microsoft is trying to stop people migrating away and implementing features which weren't planned to keep up.
So to you, Microsoft has remained its identity of "staying steady on front in a dominating position" when they sortof lost interest before?
