More specifically, it "EXTENDED DOS" to the 32 bit flat address model. The problem was that the entire DOS API was 16 bit, and assumed that everything happened in the first 640K. So if you wanted to use the DOS services with your data that was not in the first 640K, you needed a translation layer -- this is what the DOS Extender (typically via an API called "DPMI" -- DOS Protected Mode Interface) provides.
You can run 32 bit code in dos without the restrictions and performance penalty of DPMI. It's called Flat Real mode, and has been around since 1988. Himem and Smartdrv use it to access extended memory.
But you don't have to go through Himem to access memory above 1 meg. You can do it yourself and eliminate the time wasted.
The problem is debugging your code to ensure data is transferred correctly. DOS debuggers cannot recognize 32-bit addresses, so you cannot verify data is stored correctly or that you are pointing to the correct area in memory.
To lease a 120 gig drive at the same rate per megabyte would cost $860,160,000. For the purposes of that calculation I assumed 1024 megs per gig. Almost a BILLION dollars per year. Crazy.
Especially when you consider the data rate. It would probably take close to a year to read the thing!
"The reason why the active SRI 2 did not send correct attitude data
was that the unit had declared a failure due to a software
exception."
"The OBC could not switch to the back-up SRI 1 because that unit had
already ceased to function during the previous data cycle (72
milliseconds period) for the same reason as SRI 2."
"The internal SRI software exception was caused during execution of
a data conversion from 64-bit floating point to 16-bit signed
integer value. The floating point number which was converted had a
value greater than what could be represented by a 16-bit signed
integer. This resulted in an Operand Error. The data conversion
instructions (in Ada code) were not protected from causing an
Operand Error, although other conversions of comparable variables in
the same place in the code were protected."
"The error occurred in a part of the software that only performs
alignment of the strap-down inertial platform. This software module
computes meaningful results only before lift-off. As soon as the
launcher lifts off, this function serves no purpose."
"It has been stated to the Board that not all the conversions were
protected because a maximum workload target of 80% had been set for
the SRI computer. To determine the vulnerability of unprotected
code, an analysis was performed on every operation which could give
rise to an exception, including an Operand Error. In particular, the
conversion of floating point values to integers was analysed and
operations involving seven variables were at risk of leading to an
Operand Error. This led to protection being added to four of the
variables, evidence of which appears in the Ada code. However, three
of the variables were left unprotected. No reference to
justification of this decision was found directly in the source
code. Given the large amount of documentation associated with any
industrial application, the assumption, although agreed, was
essentially obscured, though not deliberately, from any external
review."
No offense, but I tend to seriously doubt anything that's labeled with the typical "medical conspiracy theory." And, I highly doubt that a doctor would diagnose a sprained muscle if what actually happened was shingles. They're two totally different things, with totally different symptoms. In other words, either you've got a really, really bad doctor, or there's some embellishment in your story. I won't speculate on to which it is.
No conspiracy. Incompetent doctor. Smart nurse:)
There is NO cure-all for bacterial and viral infections. NONE. If there was, you would hear about it in prominent medical journals. But so far there's been a lack of any evidence that colloidal silver works in anything other than sales literature. Why, you may ask? I can tell you: because it DOESN'T work.
Millions of people say you are wrong. See the links at the bottom of my web page for articles in prominent medical journals, and the test results by recognized universities.
Oh, and by the way, the FDA has no approval to ban web sites that sell dietary supplements. That's the FTC's job, because it's a case of false advertising. And let me tell you what, the FTC isn't going to shut down a web site just because some vaguely-defined "pharmaceutical company" wanted it shut down. Please, give us readers a little bit more credit than that.
Furthermore, you web site has a link to an "FDA Safety Report." All that link leads to is a page on a sales site (NOT an FDA site) that purports to be a letter from the FDA saying that no adverse reports have been reported to HHS.
Other copies of the same report are on the web. Don't you think if they were false, the FDA would shut them down instantly?
Here's a few links to FDA sites, which I trust more, and some quotes from each:
More misdirection. You are confusing the dangers of silver compounds with the effect of colloidal silver. They are different substances.
If you wish, I will supply urls for companies that use silver in various products approved by the FDA for sterilization, burn wounds, etc. And US patents including photos of the healing effects of electrolytic silver on infections that previously defied antibiotics.
Sorry, your post has so much misinformation I just have to comment.
Check out this link [quackwatch.org] for some more info.
Stephen Barrett is a master of fud and misdirection. He confuses you by citing references to silver compounds, which are not the same as colloidal silver.
He claims we do not know the concentration of silver needed to cause Argyria. He states "The amount of silver required to produce argyria is unknown." He is a doctor. He knows this is not true.
See the links at the bottom of my web page at http://www.geocities.com/mrmonett/shingles/0shin.h tm The concentration of silver needed to cause Argyria is well known, and is far more than can be obtained by drinking colloidal silver.
Barrett adds information on undocumented tests showing commercially-purchased collidal silver may be contaminated or contain no silver. This may or may not be true, but why buy it when you can make it so easily?
I'm not saying it didn't work for you, but there appears to be heaps of evidence for why you might be a little concerned about regular use.
Millions of people take colloidal silver each day. There is no documented case of ill effect, except perhaps herxheimer, which is the toxic effect of killing off large numbers of harmful bacteria.
Apparently the US FDA "has concluded that the risk of using silver products exceeds any unsubstantiated benefit." [nih.gov]
More misdirection. Silver compounds such as silver nitrate and silver protein can have much larger concentration of elemental silver, which can cause Argyria. These have nothing to do with colloidal silver, which is a completely different substance. The EPA has no record of anyone being harmed by taking colloidal silver. See the links at the bottom of my web page for the EPA response to a request through the Freedom of Information Act.
And for my own favorite test, just like chiropractric, colloidal silver users make some wide, sweeping, and exagerated claims [colloidal-silver.com] for what silver "can cure". I mean crap, that's a huge list of things it will cure or alleviate. You just have to wonder when you see that many claims of a miracle medicine/tonic.
These are not claims made by vendors. These are testimonials made by people just like you and me. They tried it and report the results. They have nothing to sell.
Colloidal silver works. We cannot say the same of the drugs the pharmaceutical industry wants us to buy.
"With that said, past few years been using colloidal silver on external wounds/infections, works quite well. I was skeptical at first until I tried it. Still using it when needed. Much better than any store bought/prescription antibio cream I ever tried."
I agree completely. Colloidal silver is the answer to bacteria and virus infections, but the pharmaceutical industry is doing everything in its power to stop people from using it, since people would not need their expensive antibiotics anymore. They got the FDA to ban web sites that offer it for sale, and to present phony information on the dangers of protein compounds, which have nothing to do with colloidal silver.
I got an attack of shingles last year - my doctor told me I had sprained a muscle and to take some asparin. This only made it worse. I went to a different hospital several days later, and the incoming nurse spotted the symptoms immediately. I didn't wait to see the doctor, but went straight home and brewed up a batch.
Likewise, black holes are just an educated guess at what might be at the centre of galaxies or left behind in the wake of supernovae. For all we know, the absence of light in these areas may well be merely extremely dense clouds of cosmic dust rather than pinpoints of near-infinite gravitational power.
The Max-Planck-Institut für extraterrestrische Physik has been tracking the star S2 near the center of our galaxy since 1992. After measuring 2/3 of the period, they are able to confirm:
"Those of us who had hands on experiance with the Accutron found out pretty quickly that they had a serious FLAW...."
They didn't take too well to strong magnetic fields either. I was at MIT in 1967, and a graduate student was showing me around.
We found a huge permanent magnet from an old military magnetron mounted on a stand. I decided to stick my hand between the poles to see if I could feel anything.
The graduate student spotted the accutron on my wrist and said "Don't do that!!"
Too late. My watch went sproiing and quit. When I took it apart, I found the tuning fork poles had been pulled apart, ruining the mechanism.
I immediately bought another one, and took much better care of it.
"The second field is that of basic electronics. The big costs here will be an occiliscope and an eeprom burner. With these tools, most any project can be made."
How about a DC to 7GHz sampling scope for under $200 in parts that lets you recover signals buried in noise. I've just invented a new sampling technique that lets you do this. The basic theory is described here
http://www3.sympatico.ca/add.automation/sampler/ in tro.htm
The first application was a wideband TDR to replace an old Tektronix unit, and the results are posted on my web site.
How about an octave-bandwidth DDS synthesizer from 1 to 2 GHz, with noise performance comparable to high quality commercial gear. Check
http://groups.google.com/groups?lr=&safe=off&gro up =sci.electronics.design
Look for John Miles or "Hybrid PLL schematics (was Re: AD9854-driven PLL)"
The pcb should be out soon at very low cost.
John's synthesizer would make an excellent trigger source for the sampler using the heterodyne technique described on my web site. It would also make an excellent general-purpose synthesizer since it has octave bandwidth and any frequency can be generated by dividing down. Of course, it would also make an excellent local oscillator for direct conversion receivers like the K2.
" Perhaps they all fell victim to their own diseases."
Most likely they would have their own version of the FDA and pharmacutical giants. These walk a difficult line between curing someone so they no longer need doctors, or killing them through mistakes. Either way, the victim no longer contributes to company profits in a trillion-dollar business.
There are other effective ways to cure infections whether caused by bacteria or viruses. Medical science is helpless against the shingles virus, for example. But a simple circuit made with two 9-volt batteries, some distilled water, and silver electrodes cured my attack. For proof, see
>Where can you still buy Win 3.11? I'm assuming it must be available somewhere for a reasonable price.
It used to be available on the net. I downloaded it as a backup for when my floppies die.
Probably the best place is a scrap 486 or P100 machine that someone wants to throw away. It will probably have a bunch of graphics editors like Corel, PSPro, and other stuff already installed.
You can use LapLink to copy the files to your hard disk. I have succeeded in being able to move programs to any directory by simple editing. Sometimes you need a binary editor to change hard-coded directories in the exe's. The only one I could not move this way was was Excel 5.0
I run Opera 3.62, Netscape 2.02, and MS Explorer 3.0 and 5.0. If I cannot view a site in Opera or Netscape, I try IE 3.0, then the humongous bloatware 5.0 version. If it cannot view the site, I go somewhere else.
There used to be a lot of legacy Win 3.x code on the web, but it is rapidly dying off. TuCows and some of the other shareware sites still have a few.
You cannot run all the latest bells and whistles crap, but I see very little need to do so.
As I mentioned in another post, I wrote my own file management software that is about 10 to 100 times faster than GUI-based programs. Using Flat Real Mode, I can access all xms memory for my own code. See
http://mr_monett.tripod.com/frm.htm
I plan to get a machine for Linux soon, but the only reason is to run the Eagle pcb layout software. I'm very happy to stay with DOS and Win 3.x, and continually extend the capabilities of my own stuff. One day I won't need Windows for anything:)
>I have to wonder.. How fast would Windows 3.1, DOS, or OS/2 boot on a 1.4 Ghz Athlon?:)
I'm one of the diehards who stuck with DOS and Win 3.x. I wrote my own file management software based on locating files quickly, then calling editors or viewers as needed. It is exactly the opposite of Windows, where you select a program, then try to find the file you want to work with.
Each file has a comment attached that stays with the file when I copy or move it to a different directory. The software automatically searches in the filename, then the comment info when searching in a directory. This makes finding a file very fast.
It runs on top of DOS, and calls DOS or Windows programs as needed. I estimate it improves my productivity by 10 to 100 times over GUI-based software. It is ideal for finding files in directories that may have 5 or 10 thousand files - try scrolling through the tiny file viewer in Windows to locate an individual file. It's next to impossible to get the right one.
I cringe whenever I see anyone trying to find a file in Windows or Linux. The amount of time wasted is horrible.
I never have problems with viruses - they won't run on Win 3.x.
And I dont' have to reformat my hard disk and reinstall Windows every three months like everyone else I know who runs the later versions of Windows.
DOS 5.01 boots in less than one second on a K6-450.
WFWG 3.11 boots in less than four seconds if you don't have too many program icons loaded on the desktop.
I plan to upgrade to a 1.4GHz soon. I expect the boot times will be a tad faster:)
>>Yes. Schematics and parts are readily available.
>Where?
Too many places to list. Check the patents - here's a fairly recent list (caution large pdf files):
http://www.aetherwire.com/CDROM/General/numbers. ht ml
Or search Google "uwb receiver".
>My understanding is that the court told McEwan to go pound sand last year. Do you have more up-to-date info?
McEwan claims the patent was reinstated. Fullerton claims it is worthless. I tried to follow both arguments but gave up. It is too confusing and you really have to invest a lot of time. This is the situation that makes investors nervous, or should.
It's probably best to check both sites for the latest info, but it's clear the argument will go on forever.
>- Can an enthusiast make one of these "impossibly cheap" devices?
Yes. Schematics and parts are readily available.
>- Are as the article suggests these devices really going to take off within the next year or will they be suppressed as the article suggests other technologies will be.
There is a patent conflict. Thoma McEwan of Lawrence Livermore Labs copied Time Domain's ideas and patented them. Manufacturer's will face litigation expense and could end up paying royalties on both.
>- Is it really that resistant to interference? We're using so many frequencies at one time, can they really not clash?
Yes. Spread Spectrum works now by switching frequencies in a pseudorandom sequence. Receivers that are not on the same sequence cannot hear the transmission.
UWB works on the same principle except it uses time slots instead of frequency slots. Receivers that are not on the same time sequence cannot hear the transmission. As mentioned, UWB is highly secure and difficult to detect for this reason.
>- Will it interfere with traditional radio signals? I.e, it seems to clobber other reserved EM frequencies to make use of high bandwidth. Would this mess up our telly or radio?
Probably, but only if the transmitter is very close (several feet) and you are trying to listen to a very weak signal.
If many transmitters are in use nearby, it may affect GPS by raising the general noise level. GPS works on very weak signals.
- Does anyone have experience to say whether this stuff is really as good as it proclaims to be?
A lot of people have worked on it with good results. Yes, it works.
The antennas have to be specially designed for broadband. They may be larger than practical for handheld phones, but fractal antennas may reduce the size.
- Finally, there must be more downsides than just messing up radio astronomers
It can raise the general background noise level and affect reception of weak signals. However, in an urban environment, there are plenty of signals that already raise the noise level. Radiation from Local oscillators in superhet receivers (probably hundreds of thousands used at different frequencies), cellular phones and other mobile transmitters (this really is bad for radio astronomy), industrial process like arc welding and power conversion, motor starting transients, automobile ignition noise, temperature controllers using bimetallic sensors, light switches, ad infinitum.
Electrical noise pollution is a part of modern society. The noise added by UWB may well be lost in the background noise that already exists.
Who in their right mind would expect reliability, security, and privacy from anything Microsoft does?
Since when has Microsoft demostrated the corporate ethics and programing capability needed to handle the responsibility? And who would place their personal files and other sensitive information on the net under the control of Microsoft?
I do archive sensitive stuff and save it in various web sites. It is encrypted with the highest level Blowfish allows, and there are no links or any indication of the contents.
Your source file is probably generated by Microsoft. It is not unusual to see MS filesizes that are 100 to 1,000 times larger than the actual text. The padding can contain long strings of zeros, which can be highly compressed.
Try compressing a text file generated in a plain ASCII editor. You might get different results.
Your enthusiasm overlooks the recent events that shut Microsoft down. This made a clear statement about having your files and apps dependant on web access.
Who cares if.NET is better or worse than Java? After the crash, who would use it?
I wouldn't be so sure that MS is flawless and the system failures are caused by the apps. How would you know? MS could bomb during a memory request and claim the app was at fault. You have no way of knowing.
In a Brief Amicus Curiae of the Software and Information Industry association, in support of the United States
http://www.siia.net/
"Microsoft has further restricted innovation and consumer choice by withholding APIs to impede the development of products that it perceived as threats, and by fostering incompatibility between such products and Windows (or Internet Explorer)."
"The technical side of Microsoft's campaign against Netscape was designed to ensure that Internet Explorer was sufficiently interwoven with Windows so that Netscape users would have a "jolting experience." Findings 160; Gov't Ex. 334, at MS98 0104683."
All the evidence gained since the antitrust trial says we never should have trusted MS in the past, and we should never trust MS in the future.
I was very sorry to hear of your lawsuit against Eric Weisstein and
his web site Mathworld.
This was one of the more valuable reference works on the web, and
will be missed by students and professionals alike.
Purchasing your CDROM is not an option for many people. CDROM's are
slow, and errors take a long time to correct, if ever. Having this
information on the web means easy access, frequent updates, and many
willing contributors to spot errors and correct them.
Some reference material works best in books. Mathworld was an ideal
combination of links between subjects, and links to other references
on the web. Compared to the value of Eric's work, a book seems
outmoded and useless.
Why don't you let Eric proceed with his work? You would gain
valuable friends in the academic and engineering communities, and
help students who would then purchase your professional books later.

You cannot run all the latest bells and whistles crap, but I see very little need to do so.
As I mentioned in another post, I wrote my own file management software that is about 10 to 100 times faster than GUI-based programs. Using Flat Real Mode, I can access all xms memory for my own code. See

I plan to get a machine for Linux soon, but the only reason is to run the Eagle pcb layout software. I'm very happy to stay with DOS and Win 3.x, and continually extend the capabilities of my own stuff. One day I won't need Windows for anything

>I have to wonder.. How fast would Windows 3.1, DOS, or OS/2 boot on a 1.4 Ghz Athlon? :)
:)
I'm one of the diehards who stuck with DOS and Win 3.x. I wrote my own file management software based on locating files quickly, then calling editors or viewers as needed. It is exactly the opposite of Windows, where you select a program, then try to find the file you want to work with.
Each file has a comment attached that stays with the file when I copy or move it to a different directory. The software automatically searches in the filename, then the comment info when searching in a directory. This makes finding a file very fast.
It runs on top of DOS, and calls DOS or Windows programs as needed. I estimate it improves my productivity by 10 to 100 times over GUI-based software. It is ideal for finding files in directories that may have 5 or 10 thousand files - try scrolling through the tiny file viewer in Windows to locate an individual file. It's next to impossible to get the right one.
I cringe whenever I see anyone trying to find a file in Windows or Linux. The amount of time wasted is horrible.
I never have problems with viruses - they won't run on Win 3.x.
And I dont' have to reformat my hard disk and reinstall Windows every three months like everyone else I know who runs the later versions of Windows.
DOS 5.01 boots in less than one second on a K6-450.
WFWG 3.11 boots in less than four seconds if you don't have too many program icons loaded on the desktop.
I plan to upgrade to a 1.4GHz soon. I expect the boot times will be a tad faster

>>Yes. Schematics and parts are readily available.

>Where?
Too many places to list. Check the patents - here's a fairly recent list (caution large pdf files):
http://www.aetherwire.com/CDROM/General/numbers
Or search Google "uwb receiver".
>My understanding is that the court told McEwan to go pound sand last year. Do you have more up-to-date info?
McEwan claims the patent was reinstated. Fullerton claims it is worthless. I tried to follow both arguments but gave up. It is too confusing and you really have to invest a lot of time. This is the situation that makes investors nervous, or should.
It's probably best to check both sites for the latest info, but it's clear the argument will go on forever.

>I have questions though:
>- Can an enthusiast make one of these "impossibly cheap" devices?
Yes. Schematics and parts are readily available.
>- Are as the article suggests these devices really going to take off within the next year or will they be suppressed as the article suggests other technologies will be.
There is a patent conflict. Thoma McEwan of Lawrence Livermore Labs copied Time Domain's ideas and patented them. Manufacturer's will face litigation expense and could end up paying royalties on both.
>- Is it really that resistant to interference? We're using so many frequencies at one time, can they really not clash?
Yes. Spread Spectrum works now by switching frequencies in a pseudorandom sequence. Receivers that are not on the same sequence cannot hear the transmission.
UWB works on the same principle except it uses time slots instead of frequency slots. Receivers that are not on the same time sequence cannot hear the transmission. As mentioned, UWB is highly secure and difficult to detect for this reason.
>- Will it interfere with traditional radio signals? I.e, it seems to clobber other reserved EM frequencies to make use of high bandwidth. Would this mess up our telly or radio?
Probably, but only if the transmitter is very close (several feet) and you are trying to listen to a very weak signal.
If many transmitters are in use nearby, it may affect GPS by raising the general noise level. GPS works on very weak signals.
- Does anyone have experience to say whether this stuff is really as good as it proclaims to be?
A lot of people have worked on it with good results. Yes, it works.
The antennas have to be specially designed for broadband. They may be larger than practical for handheld phones, but fractal antennas may reduce the size.
- Finally, there must be more downsides than just messing up radio astronomers
It can raise the general background noise level and affect reception of weak signals. However, in an urban environment, there are plenty of signals that already raise the noise level. Radiation from Local oscillators in superhet receivers (probably hundreds of thousands used at different frequencies), cellular phones and other mobile transmitters (this really is bad for radio astronomy), industrial process like arc welding and power conversion, motor starting transients, automobile ignition noise, temperature controllers using bimetallic sensors, light switches, ad infinitum.
Electrical noise pollution is a part of modern society. The noise added by UWB may well be lost in the background noise that already exists.

Can anyone explain how code can occupy 25MByte?
What does it do? Where do all the bytes go?
Opera needs ~1.5MByte. MSIE takes a lot more.
I cannot believe that a few lines of code in any simple language can explode to megabytes under Windows.
Who can tell us how this happens?

Who Cares?
Who in their right mind would expect reliability, security, and privacy from anything Microsoft does?
Since when has Microsoft demostrated the corporate ethics and programing capability needed to handle the responsibility? And who would place their personal files and other sensitive information on the net under the control of Microsoft?
I do archive sensitive stuff and save it in various web sites. It is encrypted with the highest level Blowfish allows, and there are no links or any indication of the contents.
So who needs what Microsoft has to offer?
It depends on what is in the source file.
Your source file is probably generated by Microsoft. It is not unusual to see MS filesizes that are 100 to 1,000 times larger than the actual text. The padding can contain long strings of zeros, which can be highly compressed.
Try compressing a text file generated in a plain ASCII editor. You might get different results.
Your enthusiasm overlooks the recent events that shut Microsoft down. This made a clear statement about having your files and apps dependant on web access.
.NET is better or worse than Java? After the crash, who would use it?
Who cares if
You are boasting about having 85 hours uptime?
I wouldn't be so sure that MS is flawless and the system failures are caused by the apps. How would you know? MS could bomb during a memory request and claim the app was at fault. You have no way of knowing.
In a Brief Amicus Curiae of the Software and Information Industry association, in support of the United States
http://www.siia.net/
"Microsoft has further restricted innovation and consumer choice by withholding APIs to impede the development of products that it perceived as threats, and by fostering incompatibility between such products and Windows (or Internet Explorer)."
"The technical side of Microsoft's campaign against Netscape was designed to ensure that Internet Explorer was sufficiently interwoven with Windows so that Netscape users would have a "jolting experience." Findings 160; Gov't Ex. 334, at MS98 0104683."
All the evidence gained since the antitrust trial says we never should have trusted MS in the past, and we should never trust MS in the future.

Dear David,
I was very sorry to hear of your lawsuit against Eric Weisstein and
his web site Mathworld.
This was one of the more valuable reference works on the web, and
will be missed by students and professionals alike.
Purchasing your CDROM is not an option for many people. CDROM's are
slow, and errors take a long time to correct, if ever. Having this
information on the web means easy access, frequent updates, and many
willing contributors to spot errors and correct them.
Some reference material works best in books. Mathworld was an ideal
combination of links between subjects, and links to other references
on the web. Compared to the value of Eric's work, a book seems
outmoded and useless.
Why don't you let Eric proceed with his work? You would gain
valuable friends in the academic and engineering communities, and
help students who would then purchase your professional books later.
It seems that is the right thing to do.
Best Regards,
Michael R. Monett
