Re: Are there an Infinite Number of Perfect Numbers?

WAIT A SECOND! That question is trivial. As my equation showed, there is one even perfect number for every positive integer. Therefore, since there is an infinity of positive integers, there is an infinity of perfect numbers. Moreover, since the set of all positive integers is of order aleph null, the set of perfect numbers must be of the same order. Whether or not ODD perfect numbers exist doesn't matter in this case.

Regarding ODD perfect numbers 1 (one) is an odd perfect number and it fits my equation where i = 0. I have no idea if there are any other ODD perfect numbers or if there is an infiniite number of them. I'm an Engineer, not a Mathemitician.

Reminds me of a joke:

A group of phsychology researchers at a university hired a group of teaching assistants as test subjects. They told them it was a sleep experiment, but it really was to test reactions to an emergency. Each student was asked to have a good night's sleep. In the test room there was a night table next to the bed with a large carafe of water and a glass. In the middle of the night the researchers lit a fire in a trash can by the bed.

The first subject, an engineer, woke up, saw the fire, grabbed the carafe of water and dumped it on the fire. He went back to sleep.

The second subject, a physicist, woke up, saw the fire, thought a moment, poured the necessary amount from the carafe into the glass and poured that on the fire putting it out. He went back to sleep.

The subject, a mathematician, woke up, saw the firt, thougth a moment. Then he muttered "A solution exists" and when back to sleep.

*****

My addendum: If they had used a soldier are a test subject, he wouldn't have ***** any water. He would have pissed on it.

OK, just to muddy the waters and having lived through most of this:

MOST OF THE EARLIEST COMPUTERS WERE NOT BINARY. The ENIAC which many feel was the first electronic digital computer was Biquinary! It's data bus handled one decimal digit at a time with a total of 7 lines the first 5 lines were mutually exclusive and represented the values 0, 1, 2, 3, and 4 respectively. Only one could be "high" at a time. The other two lines represent 5 and NOT 5. I have no Idea why they needed two lines but they did. If you think about it this is the encoding scheme used by a abacus. When I asked my professor who was part of the team that built the ENIAC why they didn't use straight binary, he told me it required fewer vacuum tubes and that made sense.

Until IBM announced the 360 in the mid 1960's the term byte did not have a fixed definition. Every computer had its own word size defined by the number of bits that could move in parallel. I think some scientific computers had word sizes up to about 100 bits and used binary arithmetic. However, many computers used decimal arithmetic not binary. The computer I learned to program on was an IBM 1620. It's word size was 12 bits and it could store one character or two decimal digits in a word. All arithmetic was decimal on that machine. Memory on the one I used was 40,000 12-bit words the biggest available was 60,000.

With the 360, IBM needed a flexible architecture that could scale up from smale computers to very large ones. They took the term byte which had been used as the equivalent to word size and defined it to be a fixed 8 bits. Various versions of the 360 could move one or more bytes in parallel at one time. That defintion became the defacto industry standard.

Once core memory became common, it quickly became clear that memory size was limited to the number of address lines in powers of 2. Using K = 1024 as a short-hand to describe the address space defined by the size of a computer's address register quickly became an industry standard and remains so today. It's easier to describe memory address size to non-technical pople using the binary type of KIloBye, MegaByte and so on than to talk about address register size. In 1999 the international standards organization defined standard terms for memory size like kibi, but few people use them.

Hard disks are not tied to address registers. They are organized into sectors and tracks and can be any size at all so using the binary K, M, etc makes no sense at all. The earliest hard disks were described in terms of the number of data words they held or in terms of the total number of bits.

There is an excellent Wiki article on this: https://en.wikipedia.org/?title=Binary_prefix

Octal (base 8) and Hexadecimal (base 16) are simply ways of representing binary data in a more compact form. The DEC PDP-8 had 12 bit words which could be easily represented as 3 Octal digits. The IBM 360 had words that were one or more 8 bit bytes and a byte can be easily represented as 2 Hexadecimal digits. In either case the internal representation is binary. The exteral use of Octal or Hex is just a way to make the binary easier for humans to read.

I hope this made sense to you all.

I have updated the my Tunnel A shader to support a third family of tunnel shapes. Specifying shapeFamily 2 will now generate tunnels with octagonal cross sections. See the comments in the shader for more details and the new scenes in the Experiments with Tunnels and the non-experimental Tunnels zip files.

I have also updated the Complex Functions shader by adding a few more functions. I have not yet added the ability to specify that it selects functions at random as this is proving to be a little bit more complex than I had thought - and I have been busy with other things.

I have also uploaded a new series of non-expermental "Transmat" scenes. These use a combination of tunnel and other shaders to simulate a teleportation device. The scenarios depicted by these scenes, together with other relevant information pertaining to them, are described in the Long Description text file that accompanies them.

Please note that the full versions of the Transmat scenes are complex using multiple shaders and up to 13 background images. This may be a problem for low end systems - my laptop can just cope with them. For this reason I have provided lighter versions of the scenes with the Transmat A scenes being the lightest versions and Transmat C the heaviest.

Also note that the Transmat scenes that teleport between a large number of locations take a long time to do so. In order to be able to see the full sequence it is necessary to increase the minimum delay between scenes setting on the fullscreen setting tab of the VGHD software. For the scenes that visit 12 telportation destinations this setting should be at least 25 minutes and even those that only visit five destinations require take 7 or 8 minutes to do so.

The teleporter destinations for the random destination Transmat scenes are selected from those in the Backgrounds directory. I have provide a selection of these backgrounds comprising Totem's own set of beach resort backgrounds, some images that I have downloaded from the VGHD forums and some of my own photographs. However, the supplied set is still quite small and as a result random selections from them are likely to result in the same background being slected two or more times. This does not affect the operation of the scenes, but it is preferable to increase the set of backgrounds by adding some of your own - the more the better.

As always the zip files may be obtained via the download page at TheEmusNest.eu or via the direct links

EDIT:

I made a small mistake when uploading the TheEmusTunnels.zip and the above direct link was pointing to an old version of the zip file. I have since corrected the problem and the link now points to the proper file. If you were too quick off the mark you may have downloaded the old version, if so please take the new one.

Even if the 4th power applied that wouldn't work for a binary conversion. 1024kb applies at MB level only. All other multiples are per 1000.

I'm not a math wiz, but unless it takes 1024b to make 1kb, 1024kb to make 1mb, a 1024 mb to make1gb, and a 1024 gb to make 1tb (which it doesn't), then you can't use 1024 to the 4th power for that conversion (which is what Seagate did).


phisics.nist.govExamples and comparisons with SI prefixesone kibibit 1 Kibit = 210 bit = 1024 bitone kilobit 1 kbit = 103 bit = 1000 bitone mebibyte 1 MiB = 220 B = 1 048 576 Bone megabyte 1 MB = 106 B = 1 000 000 Bone gibibyte 1 GiB = 230 B = 1 073 741 824 Bone gigabyte 1 GB = 109 B = 1 000 000 000 B

Historical context*
Once upon a time, computer professionals noticed that 210 was very nearly equal to 1000 and started using the SI prefix "kilo" to mean 1024. That worked well enough for a decade or two because everybody who talked kilobytes knew that the term implied 1024 bytes. But, almost overnight a much more numerous "everybody" bought computers, and the trade computer professionals needed to talk to physicists and engineers and even to ordinary people, most of whom know that a kilometer is 1000 meters and a kilogram is 1000 grams.Then data storage for gigabytes, and even terabytes, became practical, and the storage devices were not constructed on binary trees, which meant that, for many practical purposes, binary arithmetic was less convenient than decimal arithmetic. The result is that today "everybody" does not "know" what a megabyte is. When discussing computer memory, most manufacturers use megabyte to mean 220 = 1 048 576 bytes, but the manufacturers of computer storage devices usually use the term to mean 1 000 000 bytes. Some designers of local area networks have used megabit per second to mean 1 048 576 bit/s, but all telecommunications engineers use it to mean 106 bit/s. And if two definitions of the megabyte are not enough, a third megabyte of 1 024 000 bytes is the megabyte used to format the familiar 90 mm (3 1/2 inch), "1.44 MB" diskette. The ***** is real, as is the potential for incompatibility in standards and in implemented systems.Faced with this reality, the IEEE Standards Board decided that IEEE standards will use the conventional, internationally adopted, definitions of the SI prefixes. Mega will mean 1 000 000, except that the base-two definition may be used (if such usage is explicitly pointed out on a case-by-case basis) until such time that prefixes for binary multiples are adopted by an appropriate standards body.

Hahahaha! @Worzel.

Ok, a basic maths lesson using, erm, bases :)
Our normal system of counting uses base 10. This uses the numbers 1 thru 9 and the cypher, 0. So we have
0,1,2,3,4,5,6,7,8,9. Our brains can handle this fairly easily. We are all taught this decimal system from an early age :)

Now, imagine other number systems that use less or more digits. Eg, Base 8 uses only the numbers, 1 to 7 and the cypher, 0.
In normal base 10, each digit going from right to left is multiplying by 10, skipping the first digit.. So when you see, 1,000 you are really seeing 10 x 10 x 10. The first position on the right could be a number up to 9. Add one more and then we have 10. This means that we now have one group of ten and no smaller numbers. Now, add 7 to this and we have 17. One group of ten plus 7 little ones. Let's add some more. 1024. This number means 10 x 10 x 10 plus 2 x 10 plus 4.

Ok. Now for the trickier stuff. Hexadecimal is base 16. This uses all of the digits, 0 thru 9 plus the letters, A,B,C,D,E,F. Why does it exist? Because computers can work much faster using this counting system as opposed to our standard base 10. Why is that? Well, because computers work using electronics and only know two states. ON and OFF. There is a current passing thru a memory node or not. Just like a lightswitch :) Base 16 or Hexadecimal works on multiples of 2. (This still means ON or OFF).

Now we come to base 2 or binary. Hexadecimal is just a multiple of 2. ie: 2 x 2 x 2 x 2 = 16.
Base 2 only uses the number 1 and the cypher, 0. This is equivalent to being ON or OFF. Each point in a computer's memory is either ON or OFF at any given time. ALL computers use this binary system and all of the points stored in their memories are either ON or OFF.

So, for computers to work, they have to count in binary or base 2 maths. That's why 1 Terabyte = 2x2x2x2x2x2x2x2x2x2, etc. = 1,099,511,627,776 Bytes:)

Quelques questions embarrassantes

Всё о iStripper
21 June 2015, 9 Ответы
Bonjour,

Je me pose de plus en plus de questions à mesure que ma collection augmente...
Exemple:
1) Si VirtuaGirl met la clé sous la porte comment allons nous faire...
Personnellement je ne le souhaite pas du tout car ça me manquerait beaucoup de ne plus pouvoir discuter sur le forum avec mes ami(e)s, nos cher(e)s Team, Moderator, TripleDiamond...
et le pire serait de ne plus voir tous ces jolis petit culs :)
Ce que je sais sur le logiciel:
On peut actuellement installer VirtualGirl sur 2 ordinateurs (ça serait bien de pouvoir le mettre sur 3 ordinateurs voir plus...)
Le problème c'est que si demain le site ferme, il sera impossible de reconstruire la liste des modèles après réinstallation de Windows ou en cas de changement d'ordinateur...
La collection ne va pas pouvoir se reconstruire et du coup adieu les modèles et l'argent investit pour financer toutes ces beautés...
C'est pourquoi je me demande si par exemple:
Y-a-t'il possibilité d'acheter à VGHD un blu-ray avec nos modèles préférés pour pouvoir les réinstaller sans avoir recours au site internet ?
C'est vrai qu'il y a possibilité de faire un Ghost (Sauvegarde, Backup) de son ordinateur mais cela nécessite pas mal de connaissances et de place sur le disque dur donc c'est une solution qui n'est pas forcément à la portée de tout le monde...
  • Y-a-t'il une solution simple pour garder sa collection de VGHD dans cette situation ?

2) A présent, un exemple un peu triste.
Envisageons qu'une personne comme moi possédant une collection assez importante vienne à disparaitre de notre beau monde (nous ne sommes malheureusement pas à l'abri...)
Ce que je sais sur le logiciel:
D'après les conditions d'utilisation, j'ai le droit d'utiliser le logiciel sur deux ordinateurs différents pour moi et rien que pour moi, même si ma copine en profite quelques fois :)
Mais si je venais à disparaitre en emportant avec moi mon compte et tout mes modèles...
La collection non transmise va être perdue et ne sera donc plus utilisée et du coup adieu les modèles et l'argent investit pour financer toutes ces beautés...
C'est pourquoi je me demande si par exemple:
Est-ce que j'ai la possibilité de transmettre mon compte à mon enfant ou un membre de ma famille ? Faut-il le signaler à VGHD ?
  • Y-a-t'il une solution simple pour la succession de son compte et sa collection VGHD dans cette situation ?

Merci d'avance.
