There are many uses for a really large virtual address space. You can create common address spaces for large collections of computers and large computer networks. You can assign addresses to objects that are guaranteed to be globally unique. You can guarantee that an object's address will never be reused. You can memory map very large databases. You can move to a single-level unified address space for RAM and permanent storage.
Why do I have to go back to my place of purchase to return a drive that was sold as a system component?
Seagate sells many drives to direct customers who use them as a computer system component. In these cases, the Limited Warranty only extends to Seagate's direct customers and is not assignable or transferable. You must contact your place of purchase for warranty support.
My calculator has a 200 MHz processor in it. It also runs for months on three AAA cells. With proper engineering and programming, a high-speed CPU does not have to eat batteries.
I've read of companies that bought a bunch of SCSI drives and then set them up to only use half their normal capacity, by throwing away half the cylinders. This reduced the average access time of the drives. I'm not sure if they reconfigured the drives in-house or if the manufacturer did it for them.
Many cinematographers believe that 24 fps is a feature. It's part of the "film look" and they don't want it to change. It's too ingrained into the way that movies are made.
The major distributors can kill an old format. That's what they did to the LP record when CDs were introduced and becoming popular. They stopped accepting returns for credit on unsold records. That was enough to kill the mass market for records.
The problem is that over time, almost all manufacturers will produce bad batches or models of hard drives. I ran into that problem when I recommended the purchase of a group of IBM IDE disk drives. My timing was perfect. Everyone was saying that the IBM Deskstars were great drives. By the time we received the drives, IBM's drive quality had turned to crap, and I looked like an idiot.
Seagate may be making great drives today, but they have also had their share of turkeys in the past. I used to have some large piles of dead Seagate drives, like the original Barracuda SCSI drives.
Every time I buy or install a new drive, I look at the manufacturing date. Over the years, the supply chain has become considerably more efficient. It's kind of weird to look at the drive you just bought and discover that it came of the production line three weeks ago on the other side of the world.
I thought that a major reason why OEM prices were lower was that the manufacturer did not provide a warranty for the drive. As part of the OEM contract, the purchaser (Dell or IBM) was responsible for providing tech support and warranty service to the end user. That has caused people problems in the past when they bought drives through non-authorized distributors. Many times, that "great deal" was for an OEM drive that had been diverted to the retail market. If the drive broke, they discovered that their only recourse was to have it replaced by the distributor that sold it to them.
Correct. That's a derivative work. They started with the AT&T source and made extensive modifications and additions. Eventually, they eliminated all of the original AT&T source code.
Back in the 4.2BSD days, I looked into getting a copy of the source code for my employer. It wasn't expensive, but you had to have an AT&T source license, which was very expensive for a commercial user.
Reactors designed for the production of weapons grade plutonium generate much more waste than a nuclear power plant. In a nuclear power plant, you want to get as much energy as possible out of the fuel before you replace it. That's simple economics. So the fuel is used for as long as possible. For the production of weapons grade plutonium, you need to do the opposite. The longer the fuel is in the reactor, the higher the percentage of undesirable isotopes of plutonium in the spent fuel. That means that the spent fuel is removed and processed to recover plutonium on a much shorter time cycle. The less time the fuel spends in the reactor, the higher the quality of the plutonium produced. So the reactor is run at high power and the fuel is replaced frequently.
The operation at Hanford, and much of the early U.S. nuclear weapons program, was run on a "War Emergency" basis. That means that production was considered critical to the national security of the United States. If the plant was producing too much radioactive waste, or had other problems, too bad, we'll deal with it later. If we didn't produce enough nuclear weapons to counter Soviet aggression and expansionism, pollution was going to be the least of our problems.
UNIX was protected by copyrights, licenses and trade secrets. AT&T had plenty of lawyers. You needed a source license from AT&T to get the BSD source, as it was plainly a derivative work. AT&T did protect their IP. Thet just had liberal licensing terms, assuming that you had the money for the licenses. They had no desire to exercise "central control" over their licensees, which is a good thing. There were solid legal reasons for the way AT&T licensed UNIX, which are too complicated to go into here.
If they are using the USA as a precedent, it also applies to music played over a radio. The fact that the radio station paid fees to ASCAP/BMI does not exempt the business owner from also being liable for licensing fees if the music is used in a commercial manner.
A byte is usually 8-bits, but not always. That's why standards documents talk about octets instead of bytes for 8-bit quantities.
In reference to the grandparent post, communications engineering uses the bit as the fundamental unit. Everything is measured in bits per second. A kilobit is 1000, a megabit is 1000000, etc. A byte is a higher-level abstraction that is irrelevant in the world of information theory and communications channels.
From looking at some of the specifications for 1000Base-T, it may be called Ethernet, it may have an Ethernet compatible software interface, but the hardware implementation looks nothing like traditional 10-Mbit Ethernet. Forget about collisions and shared media. They no longer exist. A 1000Base-T NIC contains four 250 Mbps full-duplex modems, one for each pair of wires in an 8-wire networking cable.
I've seen picture postcards from the early part of the twentieth century that were obvious forgeries. Things like a picture of grandpa with his six-foot long trout. The Soviets used to erase non-persons (arrested or dead) from published photographs.
For the umpteenth time, the USA did not break the treaty. It withdrew from the treaty, following the procedures contained in the treaty for withdrawal. These procedures were in the treaty the day it was signed.

Now I know what to do with the surplus 20kW S-band klystron that I have sitting in the garage. All I need is a portable power supply.

Except when they don't.

I think there was a version of the RK05 for the PDP-8. There was also a fixed head disk, the RF08.
