Re: Overview Of New Intel Core i7(Nehalem) Processor

Greed? They're just catering to an infinite, subsidized demand, so price doesn't matter.

If the government gave out $50 coupons for oranges, oranges would cost $50.

How novel--checking how big your buffer is /before/ filling it.

Genius.

Prediction: by 2029 they'll start checking whether they own the memory they're targeting, /first/.

I think we've got some future car czar candidates here.

I read a few Windows-dressings back that each new version had to include all the old code back to 8088s, for compatibility. The old code was a nightmare no one understood, written by programmers long gone, in a Babel of languages, linked, undocumented, with some critical modules only surviving in .HEX format, the source code lost long before.

Some day they oughtta shutter those Windows, eh?

Win 9x included "thunks". A thunk allowed 32-bit code to call legacy

I've always wondered...

Terminal velocity of a human is ~100mph. A lot less if you spread-eagle.

Terminal velocity of an airplane is several hundred mph, plus there's all that metal and flaming gasoline in your future.

If you're going to crash over water it seems like you're better off jumping. (Of course you'll feel pretty silly if the pilot recovers & flies off without you :)

Yep, that's the stuff. Yeeck.

Thunking was actually pretty useful in OS/2, because there were things that were allowed in 16-bit code that weren't in 32-bit code. Specifically, as a performance hack for 286 machines, user code was allowed to do port I/O (in Intel-speak, the I/O privilege level was 2 instead of 0).

I built a bunch of parallel-port attached gizmos back in the 90s that used a 16-bit IOPL DLL (specially coded for the purpose by yours truly) to avoid having to write a device driver for the parallel port. It was about 20 times faster than the ring-3 approach to port I/O.

Nor have they honored filename extensions. When in doubt, execute it.

Just imagine the stewardesses opening the doors and throwing the passengers out of the plane as the emergency procedure :-) Besides, the velocity of the plane would be smaller with the less of weight.

BTW, I've read several true WWII stories of survival of the pilots without a parachute. The most incredible occurrence was when the plane went down before the pilot, so it exploded right under him. The shock wave mitigated the fall.

When I was playing soldiers in the mid 70s I heard about Soviet experiments involving dropping troops from a plane without a parachute. They jumped out in a sack of hay when the aircraft was flying as low and as slow as possible. IIRC the casualty rate was 50% ie 50% of the troops were capable of fighting afterwards.

Well, I'm certainly not wrong that Amendment II is equal to article 2 of the Bill of Rights, or that it guarantees the right to keep and bear arms.

You can have your hoplophobia clinically treated, you know.

Greedy bastards can't rip you off without the collusion of a corrupt government.

You forgot about the stack. As long as data gets shoved to the return stack you've left the barn door open.

...and stack.

Yep. Why isolate executable code if you'll treat a .doc as an executable.

Sorry. I forgot to add... the FDA.

Yes, Please. For that matter go forth and create them, the world awaits your encapsulated wisdom.

I have created them, at least the coding standards that allow quality programming in most any language. But I'm not interested in creating an appropriate language or starting a programming school. Frankly, anybody who follows prudent coding standards could and would want to invent an appropriate language. It's wouldn't be all that hard. ADA would do fine just the way it is. Good programming can be done in C, but C has too many hazards to be set loose on the general lot of programmers.

I know people who program critical systems in ADA and they do everything right.

Since the 8088 doesn't support its full memory space with the program counter, that question isn't really fair. The 8051 has a 16 bit program counter as dos the 8088. If you use the segment register in the 8088 you can get up to 1 meg. In the 8051 if you play tricks, you can get over a meg.
