    Then, you could keep the noisy disks in a utility room where they belong and the desktop would be a handful of small quiet cubes

    There are some products out there which let you extend DVI using fiber optics (100 yards) or electronic repeaters (50 yards). Take a look at www.gefen.com. You could put your PC off in the closet and have just a perfectly silent monitor+keyboard in your office.

    The fiber equipment is ridiculously expensive - about $3K, but the electrical repeaters are probably a bit more affordable.

    You can't do this with VGA due to the distortion and ghosting, but it works flawlessly with DVI. Also the spec on DVI is an interesting read - it was actually designed with optical transmission in mind. The data rates are insane, so it's split across four channels (clock + 3 colors, IIRC) - the total data rate for a 1600x1024 display is something like 4Gbps.

    There's nothing especially cold-hearted about the practice. Manufacturers are giving the consumer exactly what they demand - the lowest possible price. Handling and refurbishing a product, in many cases, costs more that the wholesale price of the product itself, so you can bet it's in the best interests of the manufacturer to make the highest quality product they can, in spite of the cost constraints. Software is an exception - most consumers have incredibly low standards for even the most expensive software. For those of us who demand quality software, the stringent return policies give us no choice but to try a pirated copy before we buy, or switch to OSS.

    So people usually don't get pissed off when they have to return something, if they can do so without too much hassle. However, selling a product that has been previously returned and not properly refurbished (Fry's) is deplorable.

    Diabetes, now reaching epidemic proportions in adults and children, is nearly always caused by a poor diet. Obesity is caused by poor diet and lack of exercise. As a former sufferer of eczema, I proved for myself that a lifestyle change could cure it. By converse, my lifestyle caused it.

    Tall people have tall childen, Chinese people have Chinese children, and fat people (often) have fat children. It's pretty simple. Yes, obesity may be the *direct* result of over-eating, but this behaviour is driven to a large extent by the innate characteristics of our bodies and the personalities we inherit from our parents. There are *many* factors which cause people to become obese - most can be controlled, but they're most certainly *all* influenced by a person's genes. BTW I'm not fat nor am I defending lazy fat people. I'm just trying to tell you it's all about genetics.

    You are (almost) completely mistaken about diabetes. There are two very distinct kinds of diabetes. Type 1, insulin dependent diabetes is when the pancreas shuts off completely, and often begins during childhood, in otherwise perfectly healthy children. My sister is Type 1 diabetic, she eats well, and she runs marathons. She tests her blood sugar four times a day, and has to take insulin injections two or three times daily. Type 1 diabetes is *NOT* a fat people's disease. Interestingly, the cause of childhood diabetes is not understood. While in some cases it can be hereditary, more ofen it just happens for no apparent reason. Because of this, it is seldom diagnosed correctly the first time, in children.

    You're correct about type II diabetes, it is usually caused by obesity. Generally, type II diabetes does *not* mean you are completely insulin dependent, as with childhood diabetes. You take insulin as needed and you have to watch your sugar intake, but it is not as severe as the total failure of the pancreas, as with childhood diabetes.

    IANAD (I am not a dermatologist), but my understanding from talking to a friend who has severe eczema is that it is a type of skin allergy which is usually inherited, and is common in people with other kinds of allergies. I am surprised to hear that you were able to control it though a change of lifestyle, unless by that you mean just staying away from things you're allergic to. Again, I don't know much about eczema, but I've seen a severe case of it, and so I'm curious as to what you did to cure it or cause it.

    Did I say that? In case you haven't noticed, the whole semiconductor industry has slowed down. It's easy to see what's going on with DRAM, because it's sold direct to consumers. However, as CaptainAlbert said, the prices of other ther semis are much less hysterical. When you're buying this stuff in small (less than 10K pcs) quantities, you don't have much leverage in getting good pricing as the market moves.

    Another thing you might be interested in knowing about SRAM is that it has other advantages besides speed. The interface is *much* simpler, and a block of SRAM can be easily integrated into any microcontoller or ASIC, because it's all CMOS. So when you're talking about *mega* bytes, you only use SRAM if you need the speed (and deterministic, immediate access - there's no refresh). If you need 128KB or less, you're probably not going to use DRAM because it would have to be on a separate chip, and you'd also need a controller (another 1K gates) to attach it to your CPU.
