Why not use the term "bundle" as the linked article does? This seems to be a more accurate description of what is going on.

The not removing unused elements of the library in the linker would explain a lot about the heft of OSX. Given that the applications on the whole tend to be self contained packaging all elements of a library, even those that are unused would indeed be unneccessary bloat - but an easy thing for a programmer who doesn't even understand what a linker IS to miss.Edited 2008-06-28 00:13 UTC Sat, 28 Jun 2008 00:10:00 GMT donotreply@osnews.com (deathshadow) Comments Klingon?! http://osnews.com/thread?320469 http://osnews.com/thread?320469 WTF?!

Applications bundles on OS X DO NOT duplicate any system libraries (more generally called framework), absolutely not. If an application needs to have its custom frameworks then it does put in its bundle, but the system framework are not duplicated in the bundles.

Which library?

Frameworks are dynamically linked to the executable, they are not added to the executable. So what's your point?

What do you packaging all elements of a library?

Again frameworks are contained in one location /System/Library/Frameworks
there is no packaging or whatsoever. Again, besides its custom frameworks, an application bundle does not contain any other duplication of the system frameworks.

How is the packaging process any different from a linker when it comes to condensing a bunch of separate files into the same 'file' - it's the same concept. (Closest comparison windows side would be a resource file or set of resource files compiled to a DLL)

Including unused NIB's in the package is the same as including unused DLL's in a .msi or compiling unused libraries into an executable.

That they are packaged into the same distributable 'file' though means it could incur slowdowns, as package files are basically handled as a filesystem and it's more files to wade through trying to get to the ones that are actually being used. The slowdowns from this could be compared to the old interpreted BASIC days where you could speed up some programs and make them practical to exchange at 150 baud just by deleting a few REM statements and trimming unused subroutines - stuff that was/is good during development but has no place in a distribution.Edited 2008-06-28 08:29 UTC Sat, 28 Jun 2008 08:26:00 GMT donotreply@osnews.com (deathshadow) Comments RE[2]: Xslimmer http://osnews.com/thread?320487 http://osnews.com/thread?320487 It may be a placebo effect but from my personal experience before I slimmed apps on my computer most apps on leopard would have that stupid blinking light that would blink on the dock 5 or six times before the app would open.

This release is nothing more than OS optimizations that should have been done at the time Leopard was released, or at some point along the life cycle.

Most of the slimming of apps are the fact that it seems Snow Leopard is going to be Intel only anyway.

But there are a lot more underling changed being made to security, and almost all the underlying technology.

So use Linux if you have an aversion to paying for software. Or just stick with the version you are currently using if it works?

All software upgrades are incremental. That's the nature of *any* product development. You get one huge revolutionary upgrade once every so often, and then the subsequent upgrades are all incremental evolutionary ones. Look at cars (lol, another car analogy). All Fords should be free, since everything they're bringing out should have been in the original model T anyway.

I am glad Apple figured this one out. I've been using Xslimmer, deleting useless font families, adding the Liberation font family and performing other minor things which annoy me.

"So use Linux if you have an aversion to paying for software. Or just stick with the version you are currently using if it works?

I use open or free more-often-than-not and pay a programmer when their software is excellent. Either way, I am contributing to both to free choice and a free market.

The reduction comes mainly from localization packages being stripped.

The executable is already small and dynamically loads the localization package configured from your System Settings. Sat, 28 Jun 2008 21:33:00 GMT donotreply@osnews.com (tyrione) Comments RE[2]: Xslimmer http://osnews.com/thread?320528 http://osnews.com/thread?320528

The real change will be when much of Apple's design around their bundles and interaction with various level of frameworks adjust for Cocoa versions of their flagship applications and standard OS applications.

Being a NeXT Alum, OS X 10.6 is the first release that will be what we discussed in 1997/98--Cocoa OS X.

Seriously, while the ability to only install the localizations and platform binaries needed on your machine would be nice (and, as I recall from playing with NeXT in VMware, was a feature present in the pre-Mac versions of the OS) the amount of space savings gained from moving from human-readable (and modifiable) plists to binary ones is SO minimal thatI suspect the real reason their doing so is to make life harder for the OSX86 crowd, who often have to edit the plists of control panels and drivers in order to get stuff working on their frankenboxen.

Still, this issue is something I've been thinking about lately, having had to dig more into Active Directory GPOs on a project I'm tasked to at work. While I had always viewed the Windows registry as just an annoyance in the past, when I had to modify a policy that was a stored registry value, the speed of parsing became very apparent to me. My colleague, who doesn't have any programming background beyond VB, couldn't wrap his head around why there was one registry value for a bunch of different things. It's like, it's a lot easier and quicker to parse if it's one binary value! :-) Mon, 30 Jun 2008 04:05:00 GMT donotreply@osnews.com (hurdboy) Comments millions of config files spreaded in linux HDD is worst http://osnews.com/thread?320662 http://osnews.com/thread?320662 millions of config files spreaded in linux file system is the worst solution.

Definitely not, if apple is really serious about optimization then it is definiteyl going the route of doing the easier tasks first.

Ok, then explain to me what technology is so new in 10.6 that warrants the pricetag? They're deleting fonts, drivers, and removing backwards compatibility with PPC. I'd say that makes a nice 10.5.6, but not 10.6. Maybe they've got some other newfangled software tech up their sleeves....who knows.
