Sensei

You, on the other hand, have pulled a spuriously accurate figure of 91% out of thin air.

No,

I took 91% from

https://en.wikipedia.org/wiki/Cotton

"The chemical composition of cotton is as follows:

cellulose 91.00%

water 7.85%

protoplasm, pectins 0.55%

waxes, fatty substances 0.40%

mineral salts 0.20%"

And let's at least work through the calculation- though in this case it's not as helpful as you might expect.

So, for each 6 carbon atoms there are 2 nitrogen atoms. And so the nitrogen weighs (2*14)/(6*12) times as much as the carbon.

There's 38.9% as much nitrogen there as carbon.

 

Now we need to know how much carbon there is in 5g of cotton.

Well, according to wiki

https://en.wikipedia.org/wiki/Cotton

"The fiber is almost pure cellulose."

and I'm prepared to believe it for this sort of thing.

So how much carbon is there in 5 g of cellulose?

Well, again, we have a molecular formula (C₆O₅H₁₀)_n

And from that we can see that the proportions of the weights are

12*6 : 5*16 : 10*1 or

72 : 80 : 10

and so the proportion of carbon is 72/ (72+80+10) = 44.4%

so 5 grams of it has 2.22 grams of carbon.

And that would need 2.22/ 0.389 = 5.7 grams of nitrogen

And it's wrong result.

2.22 g of carbon / 12 g/mol = 0.185 mol (all C) / 6 (atoms of C) = 0.030833 mol * 2 * 14 g/mol (of N) = 0.8633 g of N

which is the same as

2.22 g * 0.389 = 0.8633 g

Going my initial thought (and independent Itoero from post #17)

5 g * 0.91 (91% of cellulose in Cotton) = 4.55 g / 162.144 g/mol = 0.028 mol * 2 * 14 g/mol (of N) = 0.784 g of Nitrogen needed.

(difference is caused by initial multiplication by 0.91)

Although I don't understand why you calculate amount of Nitrogen, while we're interested in nitric acid in the first place.

0.028 mol * 2 * 63.012 g/mol = 3.53 g of HNO3 needed.

ps. 72+80+10 = 162

You said, it's not even closer to that value.

I was not talking about mass of whole long chain compound, but single monomer unit. Itoero interpreted it correctly.

+1

What is product of KNO3 and H2SO4.. ?

And in what proportions they need to be.. ?

Since you have asked that question, I presume you can answer it.

How many moles do you think it is?

I have to admit I don't know.

If you also don't know, why did you ask?

Can I answer by PM.. ?

To not influence answer by OP.

If you have 5 g of cotton, how many moles is it?

If you have 50g KNO3, how many moles is it?

If you have 80ml H2SO4, how many moles is it?

If you have 1000 g of water, how many moles is it?

There isn't 1,000's of different designs & drivers required for any part of the computer, it's a relatively small number.

From

http://www.drivers.com/download-help-sdu.php

"Full access to over 600,000 Software Drivers"

Again, proved wrong.

There is approximately as many drivers are there is device models, multiplied by number of OS APIs for drivers (driver developer kit, DDK, or Windows Driver Kit, WDK). Multiplied by 2 (32 bit/64 bit). Or so.

f.e.

https://en.wikipedia.org/wiki/Windows_Driver_Kit#DDK_Versions

Using generic drivers or drivers supplied by the chipset makers will work on almost every device out there.

Generic drivers are provided by Microsoft, not device manufacturer.

f.e. generic gfx driver does not have GPU acceleration, just pixel-by-pixel draw lines.

To have proper full speed of hardware there is needed proper driver from device manufacturer.

They know how to code their hardware, after all they made it. All secrets of HW.

Thanks for that Sensei, for the persistant clicks to make all my post show up negative 1, even I don't do this on any of your posts, you act extremely childish.

Pressing negative vote, means "we don't agree with what is said in post" (partially or totally),

without going into senseless discussion "why it's wrong" (objectively) or "why in our opinion it's wrong" (subjectively).

(As you ignore any reasonable argument or question. That's not blog, nor preaching zone. It's discussion forum)

Reversely, pressing positive vote, means that somebody agrees with post.

So far you have 19 negatives.

19 people disagree with you.

Something like 16 of them are not from me.

Unlike you, I have 390 positive votes.

If you would be less "angry" (for whatever reason, you are acting like that),

and didn't start with this ridiculous "I am the most intelligent organisms on the Earth",

that was deleted and end up in trash, perhaps people would like to hear what you want to say.

You missed your unique chance for making good the first impression. Not smart at all..

As for the "different" hardware & drivers you speak of, I'm not sure if you understand hardware properly.

 

In every single system, all laptops, tablets & desktops are only a few designs. They all use the same chipset/base drivers across all the different boards & add-ons that are available from the different manufacturers.

 

The boards chipsets, from older to new, consist of either an AMD or Intel base, with 1 driver being released from either one of those companies that support all their older chipsets & the newer ones.

 

As for communications devices, LAN, WiFi, Audio - They too use either an Atheros, Intel or Realtek chipset, again with 1 or 2 drivers supplied by them to support all these "different" devices, despite who "makes" the product the underlying circuitry design and chipsets are all supplied by one of those mentioned companies, using a driver from them will allow the device to function perfectly fine.

 

It is very uncommon for the OEM's to add additional design/hardware features that deviate from the "base" design supplied to them by the chipset/board makers.

I wrote PCI card driver ~15 years ago for C-Media sound card, yet another I forgot name, some version of Sound Blaster, and 3D gfx card.

Different models have completely different hardware registers.

At that time sfx card had 1 channel or 2 channels, one for each speaker.

Now modern sfx card can have multiple speakers simultaneously connected.

I have here 5 speaker system.

Method of programming them depend on how they were designed by engineers.

Sound cards with DMA for instance, require setting up address of block next to play each time when currently played block is finished (double buffering),

properties of sample (8 bit signed, 8 bit unsigned, 16 bit signed, 16 bit unsigned),

frequency, volume, and the length of data in block.

The shorter length of block, the more often we have to provide new data, CPU usage will be higher.

It's all done inside of interrupt routine. CPU normal work is suspended, all CPU registers stored, and interrupt routine installed by driver is called.

(similarly multi-threading is implemented)

Sound cards without DMA, are (were) (because they probably all extincted, not produced anymore) programmed completely differently.

There is register in which there is write-only current sample data.

Programmer has to write it, wait exact number of cycles, write again, wait (cycles), write etc. in loop.

Or utilize other interrupting routine, just to feed HW register with new sample.

(on Atari 8 bit for this purpose there was utilized DLI (Display List Interrupt), that was called 15625 times per second or so)

On the top of this there is running the main virtual channels mixing routine, which is mixing f.e. 32 virtual channels to f.e. 2 physical channels.

The more speakers sound card can handle, obviously the more registers present.

So don't tell me that driver good for 2 channel system is good also to multi-speaker card.

It's plain gibberish.

Drivers are in bigger packages for convenience of end users.

User is going downloading one huge driver archive. Does not have to bother to find exact card.

It's leaved to installer to pick up right one from library.

1) You're not doubt very articulated person. Which suggest that you're rather humanist than logically thinking mathematician kind of people.

2) Showing that proprietary security system of particular company has been compromised, does not mean entire world suffer for this. After revealing vulnerability their authors had time to fix issues.

In your ignorance, you're expanding that if some virus existed in the past, it must work everywhere, and forever.

3) You cannot send me any such packet as you claimed, because simply I don't use DHCP..

4) Intercepting DNS servers, compromising router/modem, replacing DHCP settings, is the easiest way to get in, but it's easy only on paper (that you read about subject).

You're making assumption that every body in network use DHCP. That's not always the case. Only ignorant use DHCP.

And you need your own *DNS server* (if you're professional), made in C/C++, which will be nothing alike standard DNS server exe (or you simply will have no real time access to what somebody is searching).

5) My "challenges", as you called them, have to show that you just looked up terminology in the Internet, without having the real experience in subject.

You refused to perform any of them, because it would reveal my assumption.

6) Challenge (again): which Windows API C/C++ function you have to use for installing key-logger on somebody machine.. ?

7) Making fake banking website is months of planning, testing, and you have to start from creating your own bank account, to see how it even looks like. And replicate every page, every functionality.

Claiming it's fast and easy, is ridiculous. Every bank has different security.

Intercepting bank login and password, will just show you what money somebody has on it. You won't be able to use them the most likely. There are needed temporary security codes etc.

To see what money somebody has on bank account you dont have to get login and password, just search his/her mailing box for per month send bank statement..

Couple banks here is using codes send to mobile, generated during transfer attempt. User has to enter code send to mobile (proprietary app) inside of banking account website.

Others have codes on scratch card. Even user has no idea what are they, until revealing code.

Try to bypass it. But you have no real experience, so you miss the all details.

Mythbusters security system compromise episode:

Having everyone that uses Windows on the exact same version, the same updates etc. will better allow for developers to produce better quality content and without having to constantly check for compatibility issues with their software

That's not possible. Each desktop PC and laptop is different.

Different hardware, thus different drivers installed, and different software installed.

In my apps I don't recall serious issues with different OS version, other than not being able to use unavailable functions (which means unable to even run app, with unresolved DLL entry (if they are static linked) ).

There would have to be made one desktop, one laptop, one OS, for your words to be true (like in game console industry).

Compatibility issues are inevitable as drivers manufacturers are not Microsoft usually.

And even if they are MS, they are not one person that know everything.

Corporations, are complete nightmare for anybody wanting to do with them, or to fix something in their software..

They have no bloody idea what they are doing (as they are thousands of people), who is doing, what is doing, lack of (or bad) communication, constant flow of employees, in and out.

before releasing it to the Windows Store - Which is where Microsoft is really doing all the hard work, making it more enticing for developers to make Windows Apps which can be used on a variety of devices.

Nobody is forced nor encouraged to place their desktop software on Windows Store (unlike Apple Store for iPhone apps)

Software that runs on PC, won't run on mobile phone. And vice versa.

Eventually Microsoft will be putting Windows 10 on a subscription based model, similar to that of their Office 365. This is a smart move on their behalf, and also helps out smaller businesses & home users alike.

They wish to do. That's good only to Microsoft.

This has the following advantages: [..]

For home users or students,

There is no advantage for users.

For Microsoft the advantage is clear, their revenue stream will be consistent, it will generate a more even and predictable cash flow.

They wish everybody on the world have to pay them per-month..

It is true that Windows 10 is not a "complete" Operation System as of yet, but there are a bunch of very useful and welcomed "under the hood" tweaks which greatly improve the security & performance of the system compared to any previous version of Windows.

For example, what security improvement do you have in mind?

For example, what performance improvement do you have in mind?

Another smart move by Microsoft is allowing a certain amount of the public to become part of their testing team, to use millions of technical minded users & their systems as a testing bed for the latest updates or patches before it gets released to the general public. This allows us to provide feedback in relation to every aspect of Windows, not only do they find "bugs" faster with many minds looking into each new update, but they also allow us to offer suggestion to improve on any part of the system.

If there is 1 million of people suggesting something,

vote of 1 of them has 1 per million "power",

meaning it will the most likely be ignored.

Microsoft will be releasing another major update to Windows 10 later this month, which will include all the new features and bug fixes that we have all been working on.

You have been working on Windows 10?

Right.

Then no surprise you advertise it..

I bet, if I will ask the basic question about programming Windows C/C++, you won't be able to answer..

Similar like with physics/quantum physics questions.

Windows 10 is indeed faster than the rest at shutting down & starting up even on much older systems, we are still working on improving the performance aspects of many applications within Windows 10, it will only get better as time goes on.

Try f.e. booting up Amithlon on any Intel x86 1 GHz+ machine..

The faster CPU are build, the more lazy programmers become.

Or companies hiring them, the less demanding.

The Angry Intellect, is there a thing that you *really* know?

I bet, if I would ask you to write DNS server C/C++ code, you would not have idea where to start..

Show me how are you making TCP/IP tunnel in C++ for a start..

Building magnetic card reader should allow only as much characters as is needed.

Which means sending entire source code is not possible.

Some badly designed systems might exists, but are minority. As it's easy to spot issue.

Jumping from building security system to intercepting DNS - ridiculous.

All solar systems begin with nine planets.

If Jupiter would be slightly further, or have smaller mass, smaller gravity,

instead of belt of asteroids between Mars and Jupiter there could be formed yet another planet.

It's not predestined that such planet won't appear in the future.

Objects in cosmos come and go, some are intercepted, other ejected.

Read f.e. about runaway stars and hyper velocity stars ejected by black holes:

https://en.wikipedia.org/wiki/Stellar_kinematics#Runaway_stars

If such object would fly through solar system, in the nicest scenario, planets would be ejected, and captured in the future by other star (ruining your 9 planet model).

Current methods of detection of planets are working good with massive planets like Jupiter+, that are very close to their star (so it trembles a lot).

These systems are nothing alike solar system.

BTW, there is only one Solar system. The one with the only one Sun and Earth.

Other planetary systems will have different names.

https://en.wikipedia.org/wiki/Planetary_system

Movie or image is presented to group of people who are inside of MRI or other such device.

Then from data from MRI computer algorithm is trying to figure out what people watched.

Further more, your friend at the same IQ level "Sensei" had an attempted humour in the form of suggesting that I "try" something which would most certainly kill me (or anyone) -

Once more time you show lack of knowledge in physics.

Amperage without mentioning duration (time) is not enough data.

You should ask "how long current should be flowing?".

Then we would know, you know physics.

If you have 10 kA, for 15 ns, how many electrons is it.. ?

I usually find those kinds of people lurking in YouTube or on forums mostly populated by the "younger" generation with very little to offer anyone.

So far you are the one who has nothing to offer. Instead of answering questions proving you are knowledgeable, as you claimed, you preferred to refuse them.

Simply because you have no idea what we are talking about.

Quote from your "blog":

"I have done some personal experiments on myself over the years using different chemicals & TDCS (Trans-cranial Direct Current Stimulation)."

Apparently at too small amperage.. Try 10 kA the next time.

I have a such a vast knowledge base & intellect that to others,

Oh, really.. ?

Then you should have no problem telling us what is energy released by decay of anti-matter anti-Carbon-13.. ?

To become f.e.CIA agent (or member of other national agencies) you need to pass through lie detector test,

while to become president, you don't have to.

Any spy can become president, while just extremely good one can be agent.

Sorry, I could not resist, but find it quite ridiculous. Up-side-down situation.

CIA agent has a more important position than president.. ?

The problem with crime in this instance is that we break the law so regularly in little things, like speed limits or turning across double yellow lines, or a friendly game of poker for money with your buddies, or jaywalking, or sharing your prescription Tylenol with your spouse.

I don't think so these are crimes. In my sense of these words. Maybe I should use felony instead? Or even planned felony?

Many politicians said in campaign, or interview, that they were f.e. smoking marijuana.

And apparently it didn't influence their chance to being elected.

Reverse, part of people thought, cool guy

If politician drive a car, and hit other car, and there are people dead. In democratic country it ends up in instant political death..

But if he/she would hit and run, while there are dead (or hurt) people.

Even if police would find car, he/she can refuse to be investigated by police (immunity) etc.

I would like to know whether he/she did it or not..

I told you in previous post: fear from being detected during examination would filter out anybody who has something (serious) to hide. Tiny meaningless things don't need hiding.

I completely understand resistance of politicians from this idea: they have many to hide..

Sorry for OT.

From personal experience, lie detectors are only as good as the questions asked while hooked up to it.

That's correct, dear Phi.

I would do it differently (as long as somebody know by himself/herself that he/she committed crime):

- did you committed crime ever? yes/no

- did you committed crime in 2015? yes/no

- did you committed crime in December 2015? yes/no

- did you committed crime in 20 December 2015? yes/no

(then hour, minute, if such details are known, etc)

Questions about location of crime. Country, city, street etc.

Step by step. Not one single long, full of detail, question.

Questions about year prior the one where happened something, can reveal other things from the past..

True story: girl killed her newly born baby, hide it, and then pretended it has been kidnapped.

History get media attention. And private detective arrived and offered help for free.

He secretly installed all members of family spying software in computers.

And asked them to pass through lie detector the next day (so they have night for thinking about it). As he always do, in the all cases he is involved.

She was in panic after info about examination.

Everybody passed through without any problems and objections. Except girl. She refused to be examined.

Obviously the rest family members were in shock that she refused.

Her husband, mother-in-law, started pushing her "what really happened", "we know you are lying".. All day and night long.

Detective found using his spying software, that day prior examining somebody searched net for "how to deceive lie detector?"..

Family members knew they did not do it, and who did it (which laptop,at what hour,minute from spy log,which pages were visited prior and after), and pushed her to unbearable level..

Finally she told everything. And showed where body is hidden.

Detector was not even needed. Just fear of being examined..

I think perherhaps it may be a language issue but saying John made a false statement doesn't necessarily mean calling him a liar in English. That would be a much stronger statement which would be totally unwarranted. I think he just got carried away, as we say.

I didn't call JC liar. Not now, nor earlier.

Private message discussion.

Completely unrelated to this thread.

Private means it should be keep known only to involved people, unless both parties agreed to reveal it.

JC, has bad habit of bringing back private discussion to the main forum.

What happened to English gentlemens? Extincted?

OK I will call you on that.

What false statement(s) have I made?

JC, you are mixing me with Studiot..

Even though we have both nickname starting from "S", we're different person.

[...]

I think the hydrogen leaves the jars immediately and heads skywards.

Speed of sound of Hydrogen gas at room temperature is approximately 1300 m/s.

PM me, I will tell you how to make experiment with it.

The methane also migrates quickly upwards (hence my question about gas detectors).

The nitrogen jar will take perhaps one hour to exhange enough molecules to have the same nitrogen/oxygen ration as the surrounding air

The carbon dioxide will remain in the jar and still be in greater concentration than normal on the following day.

There is experiment, that probably anybody who has access to dry ice, tried at least once in life.

Paper boats, balloons or bubbles, floating in empty aquarium.

You can make experiment how long something will float inside of aquarium with dry ice on the bottom and record by camera in timelapse mode.

(on YT people are interested in effect, instead of measuring how fast/slow it will disappear)

Same idea but with different heavier gas SF6

I think you should connect it to oscilloscope to have more useful/reliable data, with time in X axis, and voltage/current in Y axis.

evolution is false,

What is wrong with evolution?

and the big bang was an explosion.

How can he know it? Without all quantum physics/GR background really understood?

Thoughts?

Second time you're giving link to the same YouTube channel "Sentiology".

Honestly I don't believe in accidents.

Looks like you are just advertising YT channel.

Btw - Lie detectors don't do any better than chance at detecting when someone is telling the truth, so (much like IQ tests) they don't appear to be the best tool for successfully doing the job you've described as important.

Buy lie detector, plug it to yourself or your friends, and examine.

Not cheap chinese toy, that started to appear on ebay,

the latest one are based on analyze of which part of brain is utilized in while answering question - there is part of brain involved in making fantasies, that's active while making stuff up,

Then you can speak about its effectiveness, from personal point of view experience.

Until you have no personal experience, you should not talk about it. To not influence other people with this premade gibberish.

Currently you are basically making stuff up (lie detector would show it right now ). Talking about thing you have no idea about.

If somebody truly believe in "Earth is flat" and will be asked about it, obviously it will show examined person is telling truth. It's subjective truth, somebody belief.

But if somebody who committed crime would be investigated, it would 99% show lie, if person would answered wrongly. Especially if it would be MRI lie detector

Lie detector is not named "absolute truth detector" so don't pretend it to be such device.

It's lie detector - detecting something reverse to truth. On purpose making stuff up.

While I intended it to use for objective things like corruption, detecting crimes in the past, identification of terrorist, spy etc.

Currently to prosecute somebody there are needed 1) witnesses 2) evidence (or or both at the same time).

Witnesses can lie,

evidences can be contrived.

Chance that somebody lie to detector (and pass through) is less than 1%. I trust more lie detector than witnesses (that can lie, or misinterpret accident, not watching it from the start to end missing crucial parts of what happened), and evidence (that can be dissected/contrived).

iNow, now calculate probability of happening all the things at the same time lie detector on victim is showing he/she saying true, lie detector on prosecuted person is showing he/she is saying true, and lie detector on police officers and all people involved in investigations also showing true....

There is work at reading people mind.

People are put to MRI device.

And there is showed image.

Then MRI is reading brain activity.

And making computer image from what person watched:

I can tell you why I would be bad US president: because I hate corruption, and whoever would to like to talk with me, would have to pass through lie detector in front of me, asking him/her about everything.....

There is no person without sin, so it would reveal while investigation, by proper "person"...
