He outlined that Apple, like Microsoft, supports (as in provides software patches for, etc.) the current shipping version of their desktop operating system (10.4 / Vista) and one version prior (10.3 / XP). He isn't making a comment about the quality or feature set of either of the OSes.
1) SSE4 adds instructions that makes auto-vectorization by a compiler easier for a larger set of code. 2) High performance code is often written to pick, at runtime, the implementation that works best on the processor it is running on (one tuned for SSE3, one tuned for SSE4, etc.).
Actually Penryn is mostly a die shrink of existing stuff on the 45nm process. It does have new capabilities but it wont be called Core 3... they will still be known as Core 2 last I heard. Nehalem is the next big thing from Intel and maybe called Core 3.
it is true for user space applications that Mac OS X for Intel is limited to 32 bit virtual addressing.
However the Mac OS X kernel / VM subsystem, even on Intel, knows how to deal with greater then 32 bit physical addresses and supports DMA to/from such addresses. For example Mac Pros support and will use up to 16 GiB of RAM.
No it is a limit of the chipset. The Napa chipset only support 32 bit physical addressing and a portion of that physical addressing range (starting from the largest address on down) is reserved for interfacing with the south bridge, PCIe buses, integrated graphics (if being used), etc. How much gets reserved is under software control but IIRC at least 256 MiB if not 512 MiB must be reserved. Also if certain hardware features are being used more must be reserved.
players have caught up in terms of functionality and are able to compete on price. What currently still gives the iPod the edge is the integration with the iTMS.
The funny thing is many of the other players on the market, even when the first iPod shipped, had more (in some cases many more) end user features and/or lower pricing then the iPod. For example a couple players on the market at the time of the iPod could already play videos on screen or output to a TV/monitor. The initial thing the iPod had was FireWire (faster syncing and charging), iTunes (good GUI), and good UI (physical and graphical) with no extraneous features. With that Apple drove into the market and started to win almost immediately. When Apple opened the iPod up to Windows users it started to lose FireWire and gain minimal new features over the years.
Apple was smart to slowly and systematically bring out new capabilities without making existing functionality more complex... this drove a repurchase tread that feed unit volumes and hype which allowed the iPod and Apple to capture mindshare.
It is mindshare that makes the iPod truly successful and not any integration with iTunes Music Store.
ScienceMark 2.0 has the Athlons run four times faster in 64-bit mode than 32; the Core2 Duo speeds up by a factor of three.
Exactly... which again disproves what the following bogus statement...
AMD chips go 30% faster when 64-bit. Intel chips go 5% slower when 64-bit.
No data that I have seen anywhere supports a statement like that... Core 2 chips are faster when in 64-bit mode (assuming compiled to utilize additional registers, etc.). The only likely edge case would be a pointer heavy data stream that causes cache to be blown out because of the 2x pointer overhead but you would see such an issue earlier on the AMD chips because of smaller caches (granted the AMD chip can offset some of that because of the lower latency memory interface).
AMD's chips are proven, Intel's new offerrings may be technically interesting, but they are unproven
Huh? The Core 2 is based on technology used in the Pentium M which itself was based on technology from the original Pentium families (not P4). The Core 2 family in some ways has a more developed history then the Pentium 4 (NetBurst) family did. Also unlike the Itanium the Core 2 uses x86-32/64 ISA... just like current AMDs processors.
Anyway the Core 2 Duo (and Core Duo before it) have been out for a while now (around a year) and are used in a huge number of consumer, prosumer and workstation systems from many vendors. You think that would prove something...
I have a similar 1080p LCD (2007 model) connected with a AV system that has a very good up scaler. In my testing the ApplTV output of iTMS content doesn't look that much different then DVDs at my normal seating distance (I use iTMS to purchase episodes that I miss and didn't record, etc). The content is also better then standard/digital cable channels even when not in a zoom/sctrech mode. Also it looks better then those horrible side stretched movies you get on some of the HD channels since it is usually encoded with a sensible aspect ratio.
I have my AppleTV set to 1080i output (should try 720p as a test some day, likely the upscaler in the AppleTV is lower quality then my AV systems on) and then have my AV unit upscale as needed (just 1080p) in this case.
Reducing reflection doesn't mean that the material absorbs more light... it just reflects less. Glass for example reflects some amount of the light (visible) that hits it while allow a majority of the rest pass thru it.
Have you every attempted to do a disclosure with Apple? It's nearly impossible.
Yeah we have. It is actually rather easy to do. Personally I would file a defect with Apples bug-reporter system and then send an email into the product-security email address with a reference to the bug number.

Huh?
WTF are you talking about?

Their is the Alaska Highway and of course Alaska and British Colmbia have a robust ferry based "marine highway".

Oops... wrong chipset linked in my post... I meant Mobile Intel® 945PM Express Chipset... sorry!

This is all outlined in the developer docs for the Intel® 975X Express Chipset
Not easy to simulate the environment accurately or fully. In the end is was an environmental factor that triggered the slide to death.
I was going to write my own comment but then I read John Gruber's Bottleneck... and well it better states my opinions on this then I could do myself.
If it is generating electricity it is affecting the movement in the air by taking energy out of the air mass.
You may want to reread his statement... the "you" refers to "programmer" not the user.
Apple may just have the balls to put up a commercial like that... I would applaud it they did.

10.5 has many more core features being added to it then we saw with 10.3 and even 10.4 .... a lot is going on under the hood.
