For example AMD64 which actually has a practical 48-bit address space allows 65,000 times the address space of 32-bit at a small processing overhead. An address space of 128bit is significantly bigger than all the data stored on earth. There is nothing innovative about getting an address space that big, it's just plain pointless at this point in time.

ARM are not trying to be the fastest or most forward thinking, they are trying to be cost effective and power efficient and a 64-bit version of their chip would free developers from the 4GB address space limit of 32-bit - to one over 65,000 times larger.

I can't stress this enough, this isn't a factor of 2x or a factor of 10x or even 1000x larger, this is a factor of 65,000x times larger...

There are plenty of privilege escalation and remote access exploits on that site. Some patched, some unpatched (not everyone keeps up to date with updates). Did you even look at the list there?

Anyway, a lot of exploits there are remote access exploits. The exploit talked about in this story is a local privilege escalation exploit way down on the severity list and it was patched before it became public.

Just a quick google search: http://secunia.com/advisories/41122

There are quite a few listed on secunia, it's a really good site. Currently lists 10 unpacked vulnerabilities in Windows Vista, none for Linux surprisingly, it must be a conspiracy against Microsoft and those damn Linux fanboys.

+ - Solving Obama's Blackberry dilemma->

CurtMonash writes "Much is being made of the deliberations as to whether President Obama will be able to keep using his beloved Blackberry. As the New York Times reports, there are two major sets of objections:
  • Infosecurity
  • Legal/records retention

Deven Coldeway of CrunchGear does a good job of showing that the technological infosecurity problems can be solved. And as I noted for Network World, the "Omigod, he left his Blackberry behind at dinner" issue is absurd. Presidents are surrounded by attendants, Secret Service and otherwise. Somebody just has to add the job of keeping track of the president's personal communication device. As for the legal question of whether the president afford to put things in writing that will likely be exposed by courts and archivists later — the answer to that surely depends on the subject matter or recipient. Email to his Chicago friends — why not? Anything he'd write to them would be necessarily non-secret anyway. Email to the Secretary of Defense? That might be a different matter."

One of them turns off randomly.
Hardware problems likely.

Both of them crash randomly when we use our analysis software (a two-year old powerpc program).
I've only used rosetta briefly and it was stable for me, but running analysis software under hardware emulation? - not the best idea.

The OS is so slow it's nearly unresponsive (to me, the people that only use macs don't have a problem with it). On a related note, the iMac makes no hard drive noise, so I can never tell if it is just slow in responding, or if I didn't double click fast enough.
So your complaint is the iMac is too quiet? -- install the OS onto a loud external USB drive then go into System Preferences -> Startup Disk and let it boot from USB by default.

File sharing is a pain to figure out.
Click on System Preferences -> Sharing and tick File Sharing -- from there your public folder is shared onto the local network, to add anything else just right click -> Get Info -> Sharing.

Mac also supports NFS (not tried NFS server though), but you can mount NFS shars with mount_nfs -P host:share destination.

I can't easily change my icon theme without buying third party software.
Never tried but I'm sure you can find free icon collections and just overwrite the default icon files in the original location.

Don't get me started on the usability of the single menu bar.
KDE has this feature although it's a bit crippled and isn't system wide - but it's without a doubt one of my favourite things in OSX.

I can't find any easy way to uninstall Garage Band, et al, so that the automatic updater stops bothering me about them.
OSX doesn't have software installation (some packages come with installers but they just copy the application over to /Applications) - every application is a special self contained directory that you simply drag to trash when you are done with it - because OSX has spotlight, it creates any file associations as soon as you copy the application somewhere spotlight keeps a track of (think a pimped out inotify daemon on Linux).

I can't find a way to move windows between desktops ("spaces"),
Click on spaces in the dock and drag+drop the window wherever you want.

And all new windows seem to open on the same desktop that the program originally opened on, making multiple desktops virtually useless.
Go into system preferences -> spaces and assign whatever applications you want to whatever space you want.

I need third party software to have an automatically changing desktop wallpaper.
This is in system preferences -> desktop -- it's right there on the first page: "change picture: every": 5 seconds, 1 minute, 5/15/30/60 minutes, every day, when logging in and when waking from sleep.

Our IT guy told me that to take apart the iMac you have to buy suction cups from Apple to pull the glass off before you can unscrew the case.
I've never tried to take apart an iMac but a quick google search shows this: http://home.comcast.net/~woojo/DFFA53A0-F23D-4541-9015-481FD3B6532E/iMac_Disassembly.html - no suction cups needed.

Macs are generally harder to disassemble and when I had to take apart my Macbook Pro for a hard drive upgrade, there were something in the range of 4 groups of different screw types to keep track of - but at least the screws don't just fall out like my on my Fujitsu laptop and then the warranty people claim you unscrewed them and forgot to screw them back in :)

I guess anything that has smooth edges and no little plastic doors will be harder to disassemble.

The "mighty mouse" can fake a right button, but you have to lift your index finger off the left side for it to work. My advisor was so used to this that he didn't even realize he was doing it.
I liked the mighty mouse but I like my microsoft mouse more and my logitech mouse even more, I had some mice I liked and some I didn't - pick whatever you're comfortable with.

I can't drag windows around by alt-clicking on the window. I can't close a window that is minimized without showing it.
No you can't, coming from Linux this is quite a pain on both Mac and Windows - if you find a solution, let me know :)

These are just the bad things that I can think of off the top of my head. There are a lot of great things that I haven't mentioned. Maybe coming from Windows I would be blown away, but in Linux all this stuff actually just works, plus all the stuff that does work on the mac. If macs work for you, great. Just realize that you're paying a 100% tax for a pretty box, and stop telling me that it just works.
My macbook pro is the only laptop I've ever had to withstand constant on the road use for almost 2 years now - I've had comparably priced Dell, Fujitsu, Panasonic (the panasonic was the next best one), Toshiba and IBM and they all had hinge problems or screen problems or battery problems all within 12 months. I still get over 3 hours battery on my 2.16ghz CoreDuo Macbook Pro after almost 2 years of use and I've dropped it quite a few times from quite high distances.

It may be pretty but it's also built to last and powerful enough to be a true desktop replacement.

If entropy is increasing, where is it coming from?
