> And yet, the Mac OS X user experience is so much nicer than the one you get with a GNU-based system; you download an app, it is self contained, it works, end of story. I have been hearing the same old story for years about how dependency-tracking package managers are the right way, and yet that environment continues to have problems, as described in the article; while the supposedly inferior Mac OS X packaging system just works, and I never have to mess with anything.

Clearly we have differing requirements. I've found the Debian user experience so much nicer than the one you get on OS X or Windows: you install a package with apt, it pulls in all dependencies, and it Just Works. I consider "self-contained" a bug and a warning sign that makes me start looking for a ten-foot pole; "self-contained" is another way of saying "inconsistent" and "not well integrated".

I am surprised to see you compare the OS X and Windows experiences. They seem completely dissimilar to me.

With Windows, it seems like every little thing needs some complex installer procedure that splats files all over the system. Every program needs dozens of DLLs, and the only way to get rid of it is to run an uninstaller that hopefully remembers everything it created, and even more hopefully doesn't break anything else on your machine.

With Mac OS X, there's generally no installation process at all. You download the app, and you put it where you want it to go, and then you run it, and that's it. Nothing goes anywhere and you don't need any special process to manage it.

The experience I've had on Ubuntu is sort of midway between these. There's a complex installation process, and everything has to deal with it, and shit gets plastered all over your machine and there's no way you can keep track of it all, but at least things generally mostly work most of the time.

But really: why manage complexity when you can do away with it?

[vacri]

and you don't need any special process to manage it.

You're speaking of apt/packaging like it's a bad thing, when it's awesome. Want to download a new OSX or Win app? Open your browser, hunt it down, in the case of Win, figure out if you can trust the site, download it, open the downloaded item and do the install dance, and then have it stay sessile on your system, never updated... unless it has its own phone-home system - and now you have more crap on your system.

Want to install a package with package management? It takes literally seconds plus download time. Package management systems are all about doing away with managing complexity.

[schmonz]

If you think OS X's approach has done away with it, you're wrong. Maybe you've found it a worthwhile tradeoff, but flattening each application's dependency tree is still a tradeoff: you get truly independent applications, but you pay for it in duplication, the costs of which are well enumerated in binarycrusader's post. Maybe you mostly don't encounter those costs. Maybe you even believe most people mostly don't encounter those costs. But they do exist.

[JoshTriplett]

Exactly. The "self-contained" approach means I can't just upgrade a library once and have everything using it Just Work with the features enabled (or bugs fixed) by the new version.

[marssaxman]

It's not going to just work all the time. There are so many possible libraries and possible versions of those libraries and their sub-libraries that it is possible, even likely, that nobody in the world has ever tested that precise combination of components before. You don't know whether it's going to work until you try it, and when it doesn't work, it's up to you to figure out what went wrong and fix it. This seems like a monumental waste of time. I would rather use a complete, monolithic application built and tested by the app developer, leave it the way it came, and upgrade it when the app developer has a new, complete, built, and tested version I can use.

[JoshTriplett]

Personally, I'd prefer a library version tested by a huge number of people running a given distribution than one tested only by the developer of a single package.

[brigade]

And the opposite approach means I only need to update glibc once and flash audio is broken.

> you install a package with apt, it pulls in all dependencies, and it Just Works

And what happens in the case of a package not available through apt? ("Sorcery! All applications must be packaged! All shared libraries must be packaged individually!")

And there went your afternoon installing some just-slightly-uncommon piece of software

[vacri]

Then you fall back to this 'superior' individual packaging method. I don't see how this is a counter.

[randallsquared]

If you packaging partisans manage to convince developers of the merits of your position, the individual packaging method won't be easily available: it'll be "wait for the OS maintainers to decide to include the newer version" or "make; make test; make install" (i.e., be your own packager).

[gizmo686]

The developers are still free to package it themselves and distribute installers as .deb, .rpm ETC. If they have a dependency not available in your package manager (or to old a version), they can either also send you that, or have you add their PPA. The only significant problem I see is that their is a fragmented market of packaging systems, which makes it difficult for individual developers to target everyone. Of course *.tar.gz is a good universal installer for when someone doesn't use a major package manager.

[homeomorphic]

We "packaging partisans" are just saying we find classical packaging superior to the every-piece-of-software-on-its-own model, not that the latter isn't an OK fallback if there is no package.

[mwcampbell]

Or you set up pkgsrc under /opt or /usr/pkg or some such, and use that for the software where you want newer versions than your distro provides.
