z = primex * primey; suppose z = 377, how do you find the factors: 13 and 29? Now, for encryption, z is thousands of digits instead of 3.
As all pries are known, or at least only known primes can be used, why not make a table with the answers? e.g. for the one digit ones 2 x 2 = 4 2 x 3 = 6 2 x 5 = 10 2 x 7 = 14 3 x 3 = 9 3 x 5 = 15 3 x 7 = 21 5 x 5 = 25 5 x 7 = 35 7 x 7 = 49
So suppose z = 35, you look it up in the table and see directly that it is 5x7. Sure it will take some time to make that list, but once you have it, getting back should be very fast compared to figure it out in a mathematical way.
Here are the first 15.000.000 primes, so there are only 15.000.000^2 solutions to look at or 2.25e+14 I could imagine that by looking at the length of the result you can reduce the place where you are going to look. e.g. if the result is only one digit, you could only look in the one digit solutions, making stuff a lot faster.
Obviously these go to only 9 digits, so a bit more will exist till you get to m39 (or 2^(13.466.917)-1
I agree. When I read the proposal to do so, I wanted to kill these banded group. I thought they were bandits for doing so and should be shot. So proposing these bans is clearly dangerous, so they should ban the banded bandits to do the banning.
(And I must be shot for one of the worst puns in history)
Because they might not be interested to see if it as a whole can be hacked, but if certain parts can be hacked. They might be aware that it can be DDOSsed. They know that social engineering will work, so they do not need or do not want to test those parts of the security.
It is like a bargame. You have a glass with beer and on top is a coaster. You must drink the beer without touching the coaster and when done drinking the coaster must be on top of the glass again. The solution would be to take two barstools, place them close together, get the glass from top to bottom so that the coaster rests on the two stools and the glass is still in your hand. Drink the beer, and pick up the coaster with the glass.
Now you could say "why rules? Just drink the beer." But the challenge is not drinking the beer. The challenge is to solve the problem on HOW to do it. The beer is the prize.
You could even tell your employees that if somebody does get into the mailbox that way, the only way for them to claim their prize is to tell who was the leak. That then would result in directly and immediately firing the person.
That way everybody is aware of the challenge and people will be double care full about giving out any details. Make them also aware that people from IT also should not be asking for your password.
If you want to buy the domain make an offer, but a fair one or you will be added to ignore list after the first message.
Why do they need to make an offer? Why can't you put a selling price on it? That way I would know what the price is. I will also know if it is in my price range or if I should go elsewhere.
The situation now is as it seems: Say you would sell for $500. When I am offering $1.000 I am sure you won't say that you only want $500, so you steal $500 from me. When I say $200 you do not even look at the offer, even if I would be willing to go to $500.
So why not put the price on the website? It is a con (yes a con) that is done with many things where people have no idea and you just rob them of as much money as possible. Be upfront and make a website where they can look up ALL your domains and the prices you ask for them. Only then I would start to believe that you try to run an honest business.
An interesting list and I looked at each and and examined how often I needed each one in the last 30 years: 1) home fax machine - Never had a fax and now the fax is outdated and replaced by email
2) landline more likely to function in an emergency as cell systems usually overload and are unavailable Never needed one and if the emergency cell system is overloaded, the people handling those emergencies will be as well.
3) landline call to 911 is more likely to show your address to the dispatcher possibly saving your life with a faster response Never had the need and the moments somebody else I know of needed it they were all able to tell where they were or had somebody there who could.
4) landline will not be lost or misplaced Never had an issie with that
5) landline more likely to continue to function during an electrical power failure The tools that are connected to that line won't (unless I pay more for backup power). General power failure was solved by calling the company with my cellphone one time. The other time it was so general that they were aware of it before I could even call.
6) landline can provide emergency dial-up internet service I do not need such a thing at home
7) landline will not expose you to uhf radiation Never had been a worry
8) landline will not suffer from battery failure Never had been an issue.
9) landline will not suffer from poor signal quality It did once with me
10 landline is legally much more difficult for authorities to eavesdrop on Security through obscurity. If they want they will listen.
What happend to me with fixed line was that it was disconnected and cable cuts and less flexibilaty.
I still do have a fixed line for my ADSL, but no phone connected to it. I even have no clue what my number would be. If I could get whith cable what I get with ADSL, I would through it out.
Even though all the arguments are valid points in a technical sense, they happen so few times that it becomes moot. I rather realize that things can and will go wrong and be prepared for that then to think I can prevent everything by adding redundancy.
I pay 10EUR per month for my fixed line (used to be 6.50EUR) so that would be over the next 30 years 3.600EUR for things I will never use if I would not need it for ADSL.
Considering how often I would need to be fast typing and how often I type and then re-read, I could not be bothered. Even when writing an email or this here, I stop and re-read and correct and re-write parts.
Imagine I could double my typing speed, I would not double my efficiency, just the part where I am typing and I do more non-typing then I do typing. When I look at other people, they use the keyboard even less and do much more with the mouse.
I know there are people that will be much more productive if they could increase their typing speed significantly and are at the limit with QWERTY or AZERTY. I also think that that is only a minority.
I think you should not look at the WPM, which is from the time of the typewriter, but at the whole task. Say answering a long email. Some rough guessing. Say the answer is 100 words. So answering with Dvorak would take 1 minute. With qwerty 2 minutes (bit less). Now getting the email, reading it, understanding it, looking for what to answer and perhaps taking action on what to do takes up 20 minutes. So with that specific mail, instead of 22 minutes for the task I would take 21 minutes.
So it depends heavily on the task as to the usefulness of the training time. I just pick and type with basically three or four fingers yet I am often faster with a task then somebody else who is much faster at typing.
I do something similar. In Belgium the standard keyboard is Azerty and I use QWERTY. Not only that, I have a Happy Hacker keyboard, so people are confused twice. Next I use a trackball instead of a mouse and that is not so much fun for most.
This results in nobody sitting at my desk when I am not around. Many people are now getting portables and as they can't find a qwerty one or don't want to buy one, I don't have the possibility to work from home during the weekend.
That is not a coincidence. It is just it has a very high improbability that it would happen. Apperently you dropped to a chance of 1:1. Now it is 365:1 (and falling).
For the same reason that african american citizens still get regularly handed hateful scorn by racist morons who clearly weren't alive before the Emancipation Act?
Or by naming the whole group after a continent one of their ancestors came from. Just out of curiosity, how do you call a person who has three white and one black grand parent?
There, corrected that for you. As long as you are giving out information, people will use it in ways that you might not agree with. As long as nothing is done about this, these things will happen over and over again.
Transferring data that can be linked to a person should be made illegal. And yes, this should go a long way. e.g. Visa would be able to see how much I spend, but not what I bought.
That is how an intelligent person would look at it. What the RIAA would do is sue everybody, regardless if they are the source or not. It would look at a way to sue people who just looked at your profile, because they can.
The reason they should not do it is because it is wrong. Just because they can does not mean they should. There are or at least should be laws against just transferring your information to others. The "but then don't do business with them" excuse is crap.
That excuse is just a way of enabling all companies to do whatever they like.
A woman's laptop should use one of those IBM Thinkpad TrackPoint things for the pointer device.
It is not that they should, but that they COULD actualy use it. I can't even find the thing in the dark. Men are apparently much better using something like this here.
When I went to the docter I told him "when I press on my chin it hurts, when I press on my knee it hurst. When I press on my stomache, it hurts. What do I have?" * You have a broken finger. What can I do about the pain? * Stop pressing things.
So if you are worried what you see when you do a search, stop doing that search. Sure you can blame those evil downloaders, but perhaps it is just that those people interested in your book now already have bought it and have it o their shelf. And there also is a second hand market. Why would I pay 46.82USD on Amazon if I can buy one used for 3.77USD?
I assume the text has not changed while it was in the hands of somebody else. Also perhaps other books on the subject are just better and perhaps many people can just google for the information.
Prize yourself lucky you sell any books at all and feel flattered that it is good enough to copy. The time you gain by not loosing sleep over it you can use to write another book.

I am sure the owners of X.org will be happy that you abused their domain (unless you actually OWN that domain)
Best use example.org, example.net or example.com as that is what they are for.

At least the UK understands that security through obscurity is the only way to go.

Because even though they have their second amendment they were too lazy to enforce it.

Great to listen to when sitting in traffic on the way to work/home. Much better then listening to the radio.
