`Nother thing about the older embedded OSes such as RTEMS is that they started out on processors without memory management. Now MM is great, giving you the ability to protect tasks from each other. But good old ROM gives you write protect on your code, and MM harware takes up a fair amount of chip real estate and slows things done a bit - more important a few years ago then today, but still can be a consideration on smaller products.
Yet another thing is that the older embedded OSes were multi-thread, not multi-process. Again plus and minus, thread context switch is usually noticebly fast than process context switch. I've seen a number of programmers that learned in the DEC OS or Unix environment get tripped up in just-multi-thread embedded jobs, forgetting that all tasks share global variables and system resources.
And a fully linked OS+application tends to come up much faster than a "bootable" OS. Most people would be annoyed if their TV, microwave, or cell phone took as long to boot as their desktop *NIX - MSWindows isn't even in the same state much less the ballpark.
I'd like to thank Congress for further pissing away my tax dollars
And there is a good way to get conservative Congressfolk to oppose it. Write them a letter saying word to that effect, and asking them if they support this waste of money and intrusion of the Fed's into individuals' lives. If you've got 'liberals' representing you then word it so as to question their liberal credentials.
Hmmm... I thought that the recent releases of OpenBSD allow you to encypt the swapfile. This is automatic, the OS picks a new key every boot so you can't give it away by writting it on a stickynote.
Actually gold has intrinsic value that, given the relatively limited supply, would keep its price fairly high. Gold's main usefulness is its corrosion resistance, its good conductivity is also important. Think of all the gold plated edge connectors on PCBs and so on. Gold is used to line some chemical apparatus in the manufacturing world, in sizes where glass is not practical. And thin gold film makes a good IR mirror.
The short-term fluctuations in the price of gold are mostly driven by irrational beliefs. The 100-fold drop in the price of gold if the seawater extraction is a WAG - check the price of bromine or bromides, where bromine is roughly 10 million times as abundent in sea water as gold and is often extraced from brines (such as the Dead Sea) where it is a hundred times more concentrated than in sea water. It cost money/energy to move all that water...
(I don't think the idea is that great. However, when I think of the number of drives I've seen damaged by people kicking the box the drive is mounted in...)
The effective bus speed for write to video is still 10M bus-cycles/sec (80 Mbytes) and might be faster depending on how smart the parallelserial conversions are. That's not too slow so long as you're not doing a full video RAM rewrite. Remenber that the video card itself is at the desktop, so stuff done in its memory is full speed, as is the video output to the display. Moving the mouse takes very little bandwidth and shouldn't be impacted.
Note that this is different that X-servers, in that you're not jumping between client and server to get things done. The CPU just writes into the video card, wit the limitation of the 80 Mbyte/sec or so bandwidth. The same video drivers work without and with the serial link between the CPU and the display card.
I got the impression that the link is per machine-desktop, not shared as standard (Etherent) networks are. If so you've got full bandwidth to your desktop rather than the slice of a network you get. And, replying to those who said (more or less) "great, you'd need another set of cables" - with this you'd not have network connections to your desktop, those stay back in the sealed off room with the CPU, RAM, and disks.
The best think about this product is that it might help fight shared main/video memory, as grabbing pixels from RAM to stick on the screen would place a large load on the serial interface.
Because most police have shown that they often overstep the law in their snooping, and all too often do so not becasue of illegal activites on the part of the investigated person, but rather because someone with clout doesn't like that person. Check the history of the anti-war, womans suffarge, and civil rights movements in the Western countries, and religous and anti-Communist movements in the Eastern block. Look at China today. Look at how many activities are illegal now, and what has been illegal in the past that is now considered acceptable or even good (join a union, eh).
In some cases someone was being wiretapped and 'bugged' because they were suspected of some illegal activity. Sometimes the activity was vague, "engaged in counter-government actions". It might be even less specific, the bugging was actual a "fishing expedition" where the policed hoped to find the person doing something they could come done on them for.
And in many cases the person being investigated wasn't doing anything illegal. However the bugging turned up other activities that could be used against that person such as pre/extra-marital affairs or homosexual actions, talking with known Communists/Imperialist-running-dogs/fags/skatepunk s, dressing in drag (hi JEH!) or watching the Partridge Family (or using Open Source Software).
Such activities were not illegal, or were of a much milder degree than the reasons given for the bugging. (come on, half of British humour is based on men in drag, does that threaten national security?)
And then there's the general privacy aspect - do you want your love emails to your wife going into the police databases? You could be suspect of wrongdoing even if you aren't actually doing anything wrong; or you could be in commincations with someone else who is being investigated. Or the loss of freedom - if you say "just don't snailmail/email anything you don;t want others to see", then does not that reduce your freedom?
One more example - you and your fiance are planning the post-wedding honeymoon on the phone. You conference-call the hotel in Vegas, which happens to be owned by folks the FBI is watching. Matter of fact, the person taking your reservation is under a wiretap authorization. According to the FBI wishlist for CALEA, your call to them would be recorded, and the recording would continue even after they (the wiretapped suspect) had dropped out of the conference call - leaving your and your fiance to discuss what you would be doing on the honeymoon for the benefit of the FBI voice recorders - and that converaation would be legal for them to keep. (that provision has been challanged and possibly overturned).
This looks like yet another "serial backplane" technology. It's not just the slow I/O on long cables, or an X-server (which still takes smarts at the user interface end).
Chop the buss into two sections. One is CPU, RAM, and dsik I/O; the other is the PCI slots including the normal slow I/O (serial, parallel, USB) and the video card.
Now stick fast parallelserial converters on the chopped ends of the buss, run the serial throug LVDM drivers. In the case of C-Link they may be doing a multi-level modulation scheme to get several bits into every symbol (bits vs. bauds, right?)
So the PC with its disks and RAM sits in a locked up, air conditioned room where the cleaning crew can't bang into it, and the just-fired employee can't give it a swift kick.
On the desktop is the other end of the buss, a box with PCI slots and the standard PCI-interfacing I/O chips for slow I/O. No smarts, just the serialparallel converts and a PCI interface plus whatever cards you stick into the local backplane.
Do a little math : take the width of the PCI buss in total signals - data+address+some handshaking - and divide that into the 1.3 Gbps of the serial interface. That's the distant PCI buss speed in buss cycle per second. Now, the CPU, RAM, and disk are all on the standard full tilt buss so they run fast; keyboards and mice and serial ports aren't going to notice the reduced buss speed, it's just the video that might suffer.
Patents were intended to "promote the Progress of Science and useful Arts..." . Jefferson and others hoped that the patent system would encourage people to publish their ideas, via the patent document, thus spreading the knowledge around; he saw this as promoting new ideas by making them widely known rather than remaining trade secrets.
Many of those involved with the setting up of the US patent system did not support the patenting of every small derivation of some concept; a patent was for some big, new, non-obvious idea. Even in the early 19th century some were worried that patenting of every minor idea would encumber further development and impede progress.
Note that European patents were often similar limited duration monopolies granted by the powers that be; however in some cases a patent had no limit on its duration.
Jefferson was for a limited duration of patent and copywrites, believing that ownership should expire with the originator of the ideas. He felt that each new generation should be free of entanglements of the previous one, that debts and restrictions incurred by one should not be inherited by the next. See
http://www.cni.org/Hforums/cni-copyright/1999-01/0 327.html
for some of his thoughts on this.
Given that a corporation is effectively immortal, the ownership of ideas (patents and copywrites) by such entities is in conflict with Jefferson's ideals.
NSA swiping patents has nothing to do with NIST choosing an algorithm for use by the general population. The AES choice is intented to be available without years of court battles about patents. And in this case the USA seems to want a standard that can be used globally, which non-US patents might interfer with no matter what the NSA said.
So if Rijndael wasn't invented here where was it? Oh, I see, you're a US-AC vs a Dutch-AC.
If you count nicotine and caffeine, both addictive stimulants, and ethanol, an addictive depressant, the tradition in European cultures goes back hundreds of years. Likewise, so does the lurid warnings and exposés on their usage.
The "typical engineer" in slightly nerdish popular literature of the last 70 years shows them as heavy smokers and coffee drinkers, with a tendency to hit the booze at the weekend parties. Readings of memoirs and whatnot of technical creative people for the last 200 years shows a similar tendency. Once there were alternative, cocaine in the later 1800s and amphetamines later on, they were used as well. An old retired ex-areonatical engineer once told me about the stimulant use by the design teams during WW2.
Caffeine was the target of a great deal of hostile writings when it was coming into popular use in Europe. Try http://www.quite.com/misc/tea1.htm as an example. There were drives to make one or another of the caffeine drinks illegal at various times in the previous century.
Downers were not that uncommon as well. A number of successful, famous people of the last 2 centuries used opium products and alcohol excessively. There's a tendency to cover up such usage, and with a loyal staff to help you through the bad days few people would know about it.
Then as now, exposés would trumpet the horrific state of people doing fill in career choice . The truly productive, creative people in that line avoided anything that would interfere with the fun of doing what they did, those who were more into pretending to be one of that group of folks tended to get lost in the socializing drug use.
Ethanol is a drug, just one that is legal in N and S America, Europe, the southern 2/3 of Africa, and most of the Far East.

Well, I'd suspect that the owners of the original item would go after on-line sources of the "blueprints" as copywrite violations. Plus there would be a push for the actual printers to have some sort of "anti-clone" feature as the music industry has pushed for on various digital recording technologies. They might even go for having a "copywrite payment" bult into the price of the "inks" for such printers, as they've tried with audio mag tape.
As for making nukes, you'd need an ink containing fissionable isotopes. Such material is already tightly controlled, and isn't the sort of material you'd like to have around your house.
Making drugs? There's a big difference between spitting ink+poweders to build stuff on a macroscopic scale, and putting atoms just where you want to. That's been done recently, gluing a couple of atoms together at a very low temperature (to keep the atoms from bouncing away before you can put them together). That's not in the near future, it's still easier to do it in Pyrex.
Ah, but you have to get him elected first. Then sue him, the Republicans will take the cue and try to impeach him. Result - 4 years of inaction by the US Federal Government, perhaps the best thing that could happen to the country.
(later the Catholic church finally denounced the conquests, to which the king of England responded by simply making his own church;)
Really? Hmmm, seeing as the Church of England come about in the 1530s or so, and the English colonies weren't started until the later 1500s, the Pope showed a great deal of foresight by denouncing the conquests before they happen, and Henry by starting the CoE before then as well.
The Spanish were busy with NA conquests in the early 1500s, having gotten rid of the Moslems shortly before Columbus made his first voyage, and decades before Henry decided he wanted a divorce that the Church of Rome would not give him.
Oh, and I believe that the "Plague" refers to the late 14th and earlier 15th centuries, a bit earlier than the Conquests. (although there were smaller "plagues" for hundreds of years to follow)
I don't recall the WAP spec having anything about requiring a circuit-switched oriented link. Hmmm... seeing as it says it can use the FLEX/ReFLEX paging formats and PDC, I'd say the WAP isn't stuck in circuit-switched-land. (no, you can't have a URL into the PDF files on my machine)
I think what is being seen is that WAP is being used in regions were the wireless networks are circuit switched because they were an outgrowth of wireline telephony. If that's the infrastructure in place, that's what you use.
I also suspect that the pricing for WAP phones is based on the carriers attempting to boost profits. Competition has pushed prices down in NA, while NTT DoCoMo has been more or less a monopoly.
Ah - but are they being told that they are giving out/up certain information? The picture frame shop might send me a "thank you" note after I used a check for paying for a purchase, but they didn't sell my name and address to mailing lists. They asked me if I wanted to fill out a frequent buyers rebate card, I could decline and if I did sign up I wasn't worried that they were tracking exactly what I bought.
You can say that people should take care and block cookies and web-bugs and the like. I think they should, too. However there is some limit to what an individual can check themself. Do you analyze the water out of your tap every week? Check to see if that soda doesn't have something nasty in it? Your new monitor gave you a free daily dose of X-rays, and now you have cancer? Tough, you should have checked it before buying it.
I think that the governments role is not to state what can and can not be capture/included in a product/what every, but to require disclosure of such information. If I know a Web site is (attempting to) collect my Email address, or that the soft drink has 0.1% benzoic acid in it, maybe it's OK by me. But at least I have the information to make the decision - if it's not on the label I can't do so.
Or use a rotary encoder. These give a pair of phase-shifted pulses as output, indicating direction of rotation. While the cheaper ones don't have a lot of pulses per rotation, some don't have any detent so you can keep turning them in one direction or the other for multiple turns.

Stop burning oil and it gets cheap. But organics can be made from just about anything with carbon it it, although some routes cost a lot.
"plastic" isn't a synonym for "polymer". Some polymers are tar-like, starch is a polymer as is hydrofluoric acid, wood is a mix of several polymers.
And "plastic" is made from a wide range of monomers. The poly-ethylene in milk bottles isn't the same stuff as the poly-styrene in packing peanuts, nor the nylon in brush bristles. Just because something is a polymer doesn't mean you can easily make it from your plastic trash. I believe that many of the current crop of polymer semiconductors are polyenes such as polyacetylene, polyvinylidene fluoride, polythiophenes (sulfur containing rings linked together), poly-para-phenylen-vinylene, or poly-anilines. None of these are very close to most packaging plastics.
Doesn't look to be the same thing; from the press release :
polymer-dispersed liquid-crystal display (PDLCD) was chosen. A PDLCD is a reflective, high-contrast, low-power display.
In a PDLCD, light is either scattered by non-aligned molecules in LC domains or the LC
domains are transparent because the molecules are aligned by an electric field.
No - but that was the point of PGP before Key Escrow got involved. T oquote Bruce at the head of the story
A stupid idea, but that's the sort of thing that Key Escrow demands.
Way back in 1998 a bunch of us cryptographers predicted that adding Key Escrow would make system design harder, and would result in even more security problems. This is an example of that prediction coming true.
As for what good is it? Not much, except in the case of a business that uses encryption and wants to be able to recover messages when an employee is not around/gets fired/dies.
