Hehe, I remember Virginia Tech having built the 3rd fastest supercomputer out of 1100 dual powermacs G5. Back then, the XServe G5 wasn't available. You can see that in the MWSF 2004 keynote (minute 25 ff). They later switched to the Xserve G5 when those came out. It had 10.28 TF for just $5.2M.
And I remember that they were very concerned about the lack of ECC memory, and were extremely eager to replace them with Xserves as soon as the G5 model came out.

Are you sure that discount applies to the NEW Merom based Macs - I don't think so?
I would assume so. The promotion applies to the Mac Pros i believe, and thats new hardware.

Arrays of cheap RAM on a PCIe card?
The RAM companies don't seem interested in making wodges of slow cheap hi-cap ram, only in bumping up the speed and upping the capacity. For the last 10 years, a stick of decent RAM has always been about �100/ $100 no matter what the capacity / flavour of the moment is.
Even slow RAM is still orders of magnitude faster than a HD, hence my point. There's various historical and technical factors as to why we have the current situation.
I've also looked at RAID implementations (I run a RAID5) but each RAID level has its own problems.
I've recently seen that single-user RAID3 might be one way forward for the desktop, but don't really know enough about it yet.
Slow RAM may be faster than hard disk but it's too slow for main memory. It could be useful for disk cache but products like that came and went. If such hardware could actually result in performance improvements to justify their costs then you'd see products that used them.
As for RAID 3, it has been used before but really has no place considering modern disk drives and workloads. RAID 3 and 4, in order to work properly, require spindle sync. Workstations have no business implementing any parity-based RAID scheme. Servers used RAID 5 when they have high capacity needs and aren't sensitive to write performance.

When someone speaks about "smartphone marketshare" he usually means world wide and not only for Botswana. But nice try. :rolleyes:
Are you real? How is that understood?
Most of the times when marketshare is discussed, its discussed for the US only. I reside in England and I know its stupid to neglect the world; but every other sale means much more to US than to the world.
Talk about CD's/DVD's/Vinyls/MobilePhones/Computers etc.
I am not saying the world doesn't count; but US is supposed to be a big benchmark. You could have at least mentioned which marketshare you were talking about.

"...Core 2 Duo chips need less electricity, drawing just 65 watts compared to the Pentium 4’s 95 watts and Pentium D’s 130 watts"
Good Lord - does anybody know what the G5 is? I'd imagine that the elaborate cooling system in the current G5 towers probably won't be needed it it's running anything like the D's...
1) The watts numbers listed are TDP (http://en.wikipedia.org/wiki/Thermal_Design_Power). They are not the amount of power the processor consumes ("drawing").
2) PPC 970fx falls in the realm of Conroe in terms of heat generation but of course the Conroe has better performance.
I should note that the PPC 970FX is a single core chip while the PPC 970MP is the dual core one... don't have good numbers for the later but I would guess it would be about 1.75 times (or more) the PPC 970FX in terms of thermal generation and power consumption.

APPLE I NEED A NEW MACBOOK PRO. I NEED FIREWIRE 800, I NEED A DL SuperDrive, i'd like MEMROM. If you had to releace a half-assed Prosumer laptop in the first place to start your transition for the love of god PLEASE update it now. Its been a LONG time since we've seen any updates. Apple is now competeing in INTEL land, were they need to keep their laptops current. Releace the laptops (notebooks in your case as you like to call them) i'll place the order and wait for them to ship. PLEASE.!

Eh what choices do you have if Apple doesn't wish to play by your needs... buy from another vendor? Let the "free market" decide? Oh wait, I forgot, for Macs there is no free market, it is basically a monopoly.

Thanks for the links, Dave! I found them both very informative, especially the one on Quartz 2 Extreme.
Do you have any feel for when we will see a roll-out of the pro apps? I recall quite a bit of rumor-mongering just before the Intel announcement. Since then it has been rather silent. I thought the sudden drop in Quake might be a precursor to something fairly soon??
I have no inside information. I just read rumour and news sites� a lot! Although I use the pro Apps for a course I take, I'm not familiar enough with them to know their typical release schedule. For instance, iLife is once a year, whereas Adobe CS products are about every 18 months - 2 years. With Apple's Pro Apps I just don't know. Anyone?

well im certainly annoyed with Apple's support right now. 3 times my Macbook has been in and now they tell me they cant FIX the problem (the only way I can get my macbook to boot up is to zap the PRAM every time). If I had known it was gonna be this much trouble I would have stuck with my pb or bought a Vaio... :mad:

I respectfully disagree. I say take it back and be ready for a much faster iMac Core 2 Duo. You want the latest, take it back. It won't be the latest for many more weeks. Core 2 Duo will be the latest for two more years.
I appreciate the thoughts on my quandry whether or not to return my 20 " iMac and purchase after the WWDC. Of course my decision is not any easier with one vote for and one vote against.
Thanks Grokgod and Multimedia for the thoughts...

That's good enough for me.
Apple's only screw up here was keeping the infinite database forever on your phone and backed up to your Mac. Their was no reason to back it up to the computer and no reason to keep the data on the phone after it was passed to Apple (encrypted, de-identified etc.) but I suspect the reason was simply "we weren't doing anything bad with it so we never even considered we should delete it later."
I guess you missed the part about the data is used in the phone to help the phone determine it's location faster and more precisely when you do want to use location apps (which I do a lot). So if you don't back the data up and you have to restore the phone (happens every time you do an update) then you would take a hit in location performance.

So the presentation should be in about 10 hours?
Has any one heard of live coverage? A livestream will probably be too much to ask, but maybe one of the tech blogs is doing a text/photo update.

Poor lost souls rely on Steve to think for them, bring them courage, and guide them in worship.
Anyone who fails to fall in line, is immediately a threat to them.
It's this weakness is laughable.
Funny, I'm a Dallas Cowboy fan, the fans are fanatics and everyone who is not a Dallas fan HATES the Cowboys. I feel the same heat being an Apple fanatic. The fans are loyal and defending of the brand while every other tech fan hates us. I need a big white Apple logo with a blue Dallas Cowboy star in it. I might be shot!!!! lol

I wonder how "Time Machine" is implemented.
Probably the same way it is in scalable transactional databases that use multi-versioning concurrency protocols (e.g. PostgreSQL and Oracle). No data is over-written, and every "update" actually creates a new record version. The concept is virtually identical, except that in databases the default behavior is to delete old versions that no transaction is using any more. Such file systems are often implemented now as MVCC-style databases with file system semantics.
In fact, PostgreSQL used to have a feature many years ago called "time travel" that would let you query a consistent view of the database at any point in its past.

So, the time machine will allow you to selectively restore files which have been deleted, yet as of present the trash can will not allow you to selectively undelete a file?
Might as well just delete the file, then restore it with the time machine!!!!
... I have a feeling the trash can may see some changes, ha

I had hoped for the ability to link files and folders with contacts in my address book, I can only hope this is one of those top secret items.
I would also have liked some way of sharing my appointments in ical with the windows people I am meeting, to date ical will send them an email with an ical attachment, but they are unable to do anything with it.
Someone please tell me I can already do these things or that I have a chance of doing them in X.5
