Even the mostly testosterone filled martial arts class has more of a chance of containing an actual attractive female than training alone at home with just those comics for company.
So it sounds like you also think that things like disk caches are sub-optimal. You are welcome to that opinion but there are easier performance targets.
they probably never saw as far ahead enough as to recognize this issue.
no, I'm guessing the tradeoff is very well understood. You trade off memory capacity to make a DMA buffer. Having a 64-bit address space will not fix this, as you are actually using physical RAM for storage of data while it is being copied to or from the video card by the DMA module.
Imagine a city with a limited road budget. The industrial areas (devices) have priority over residential areas (system RAM), so some residential areas are left without road access.
I get that. I have a CE degree, so no need for analogies:)
What I am getting it is, wouldn't the video card have a single address that the processor writes to?
This is why there is an average usable limit of 3-3.5GB of RAM in most 32bit systems. You can have 4gb of RAM, but the system still needs to allocate space to the other devices so it can interact with them. This also has to do with DMA, direct memory access, that enables devices to directly access ram (bypassing the CPU) to make Input/Output operations faster.
None of these have anything to do with address space. A DMA buffer isn't device memory mapped into system memory; it's a buffer in system memory that is copied to or from device memory.
Most computers, which are 32-bit, have a total or 4 GB of addressable memory space, which includes video memory, sound card memory (if you actually still use one) and system RAM. Therefore, if you put in a 2GB video card, you can't make use more than 2 GB of system RAM.
Why would these devices' memories be mapped directly into system RAM?
I actually got a degree in French along with my Engineering degree because of a special program at my University. It took five years but I didn't pay for most of it, and 6 months of that was spent working in France. Philips (Dutch), ST (Swiss/Italian), and other companies have offices in any places, and even the effort to learn a language goes a long way in proving your ability to work for a multinational corporation. Even when I interviewed at my current job (Finnish corp), they mentioned my French degree positively, and I don't even think they have any French facilities beyond a sales office.
There are definitely clueless kids that lose their backpacks in the airport, and they can get stolen if you so much as look away in a crowded airport and you're not touching the bag.
My father-in-law is in this category. For years he had CallWave and a dialup connection (which got 15600bps tops). When Wildblue became available, he signed up instantly and still spent less on his Internet bill.
FPGAs can do RAM as well. It would effectively be static RAM though, and not as much as you could fit on a package of DRAM. The reconfiguration would be pretty expensive and you'd have to page all your memory out to a different storage device. That would be a neat trick, but I imagine that the compiler needed to do this optimization to require a second FPGA due just to sheer size.
Actually, an Altera FPGA with the NIOS software core can be configured in software to have multiple cores, and they can drop instructions that aren't necessary.
Never, because you charge $5000, kick back $1000 to the guy who signs the paycheck, and send it to India for $3000, pocketing $1000. This is not a new phenomenon, and is probably in every ethics textbook and training course.
From the article summary above: "a variable bit-rate compression scheme being rolled out on VoIP systems leaves encrypted calls vulnerable to bugging" and "spot phrases of interest in encrypted calls simply by measuring packet size."

The horses spend their pregnancy hooked to a catheter.
Their continual forced pregnancies, after which their foals are sent directly to slaughter.
That's because he hunted them all, smart guy.

That article gives you instructions on how to use your video card's RAM like swap or a RAM disk, but not system RAM.

The Sega Genesis actually had a 68000 microprocessor so it can do 32-bit math.

Not only a work of art, but a historical artifact, just like Civil War-era keyed bugles, serpents, sackbuts, etc.

Looks like some combination of Sun Microsystems and Oracle.

Vida Guerra's has the most hype-to-buttocks ratio I've ever seen.

There is actually an understood dot at the end of every host. The URL you have written is a host named slash that is its own TLD.

Emphasis mine.
I still prefer the idea of an SUV than a minivan or station wagon to try and haul people/stuff around.
Why? Take the BMW X3 vs. the BMW 3-series wagon. The wagon is cheaper and has more space, and it gets better gas mileage.
The "Yellow Box" was the NeXTSTEP layer, which was later renamed to Cocoa.
