However if a person made a virus which took over the users cpu and lets say there were 500,000 copies of that virus sent out and the average computer could do 10,000 hashes per second then 500,000 x 10,000 = 5,000,000,000 strings could be hashed per second. That is an incredible amount of cpu not to mention the possibility of taking over googles mainframe in which case trillions more hashes per second could be done. So with the combination of taking over googles mainframe and planting a virus on every computer it would be possible to dehash at least a dozen digits if processing long enough. You see that's the thing. Hackers have access to unlimited cpu, unlimited ram etc so they can dehash whatever they want providing they can write a good virus. So with todays technology it is possible but if you still don't believe me then we will see who gets their hashes hacked. An example of this is the crc32 hash - it has already been hacked and it's only time until somebody scratches their head to crack the other hashes.

One thing I would like to say if I can get this language working on Ubuntu.
"GoGoGoogle"_"

If you wont listen then I shall show you the hard way. Attached to this post is a live dehasher written in Java which will check every combination hash to the specified digits to find the original string. Currently it will only dehash to 3 digits and any more it will freeze your computer. However with a mainframe it would be possible to do all 6 digits and very possibly more. Also the "exit dehashing" button doesn't work btw just so you know. Have fun dehashing.

I don't think that stargate is technically possible , because just the
computing power it needs far exceeds million times of world's most
powerfull supercomputer.and project blue book does not mention
anything about stargate.And Area 51 is incapable of doing these
experiments ( those are high eneargy physics experiments ) that
can be only done in places like CERN.

But it's fair enough to believe that anti gravity technology is there
and they are applying it on their fighters and war technologies.

That's why the technology was found pre-made in egypt and according to my religion we descended from the Ancients somewhere between 5 and 10 million years ago.

how to send mail without authentication one domain to another in java ?

I see it's your first post so welcome to daniweb and as for the question, you will get a better response if you start a new topic in the Java forum. Currently you have posted in the Search Engine section and very few people who browse this category will know the answer to a Java question unlike those who browse the Java section. So to begin using daniweb, go to the Java section then click the big button that says start new topic and fill in the details. Then the community will see how they can help you.

I can do without that!

I found a long way of doing it but for to the power of 50 it would take years to find the answer by pen and paper. For example 2^4

2^4=
2x2=4   (^2)
4x2=8   (^3)
8x2=16  (^4)

That is the old fashion way but wasn't sure if there was a faster way.

I'm not denying that for a second. But, if you've got access to six of the worlds fastest computers, You've got bigger fish to fry than my websites.

And, the same applies for ANY hashing function. You cannot create a "future proof" hashing/encryption function.

So how about you quit pointing out the obvious, and get back on topic?

The future comes fast. Have you read this article? Yea, would like one of those in 10 years and everybody will have one of those on their desk in 10 years. So the fact is if the government who buys these super computers can dehash or hash-match then hackers can take over those computers to do the dehashing/hash-matching. This is only in about 2 years. Untill then all the hackers will need to do is take over more computers. Example, perhaps Googles mainframe. Imagine a hacker in controll of googles mainframe doing just dehashing/hash-matching and Googles mainframe processes over 5% of the internet including google apis. So one simple system that can be hacked where 5% of the worlds cpu can be use for any single job. That has already happened twice in the past year for about 52 hours. Of course google tries to cover it all up.

Don't have a clue what it is. Perhaps try the evil msn?

However theoratically if you hacked 6 of the worlds fastest computers to calculate every possible combination hash then there is nothing stopping you from retrieving the original string. And Basically what you do is you loop through the char() function to get the character and use a loop to piece together strings all in alphabetical order then hash the 255^100 strings and see what hashes match the original hash. Then if the computer hashes a string and the resulting hash is the same as the one found in your database then bingo they have your original string.

I know some technology the US government is hiding. A stargate that was found in egypt where the US government has been able to trade technologies with species from distant galaxies then they made a movie about it so nobody would suspect it.

You know you are a geek when you can say your name in binary without having to think twice. 01110111011010010110110001101100011010010110000101101101 :P

That binary value = the int 33611436624798061
also the 23 in cwarn23 = 10111

Found a bug.

if (!start)

The above line is meant to be the following:

if (!$start)

OK, I gotta throw my 2 cents in here. There is no such thing as a de-hasher. A hash is ONE WAY. The only thing that can be done is to produce every possible string against the salt using the same algorithm to produce the same hash. It's not possible to reverse a hash, that's why it's a hash.

Hash one way, your thinking in terms of 1998 technology. Today we have supercomputers with millions of cpus with petaflops whatever that means. So when the performance of the average computer increasing every month it makes it possible for the computer to hash every combination until there is a matching hash. And with today's average home pc, it is possible to crack a hash where the original string was ONLY 3 digits long and that takes about 40 seconds. However with a supercomputer perhaps something like 7 digits could be cracked in that time. Keep up with the technology dude.

Looks like google doesn't let this language run on windows because windows is too popular. hehehe At least it will run on linux and mac. Unfortunate that it's not cross platform for all systems.

I would say you know your a computer geek when you have done over 1000 posts on daniweb. lol That's me alright.

Btw, how do you calculate to the power without a calculator? eg. 1024^50 using only addition, subtraction, multiplication and division. Just wondering as it would have been handy in the past without doing endless multiplication.

what you think about these technologies ? Are human already able
to exploit the concepts of high energy PHYSICS ? Or just aliens just
give them to us ?

Well from my understanding, I believe earths scientist just don't have enough knowledge of particles to be able to create anti-gravity vehicles. Theoretically it would be possible to create a hover car without any rockets just by sending a positive charge to the earths core. This would create a magnetic effect where the positive charge from gravity against the positive charge of the vehicle would force the two to separate but of course, no scientist has been able to work out how to make such a charge identical to the charge of gravity. That is also where they loose when creating space shuttles for creating gravity systems because currently the space ship needs to rotate for artificial gravity.
So as for the original question I would say humans can master physics before humans become extinct and I would say the nearest life in the universe is in the Pegasus galaxy (Atlantis lol).

Did you know that with todays cpu speeds the average computer can calculate the reverse lookup of any hash that contains up to two digits. So if there are >=2 digits being stored in a hash then the computer can calculate the original two digit string within less than a second. Just a thing I learnt when creating a dehasher in Java.

Oops... Wrong thread for this post...

Played for me but the video has a quality rate of 250kbps and a 6 second buffer. Unfortunately any less quality and the code is grainy. I'm using Opera 10 but does anybody recommend a better wmv2flv converter... Also can anybody else get it to play...

I suspect it is because when you use the http:// or even the www. it forces the search engine to only check for backlinks containing that prefix. So if for example the backlink did not contain the full http:// in the url then it would not show up in the results for your first search term. So for that reason you are not going to get very reliable results with your second search term and will only get reliable results with your first search term which is the following:

www.arif-4121f.info -link:www.arif-4121f.info

i dont tink they wil fix it i made a forum post they said its a error that is rare and that the unhasing seemed like nothing to do with it whne i red the posts they made. then i heard that its caused by stuff that i know i didnt do. so it must be the dehasing they are liars. i think they want to incriminate anyone for dehashing when they dont~ i dont dehash i am not a cirminal

A person who dehashes info isn't always a criminal. Sometimes people will need to retrieve personal data etc that has been hashed and that is where a dehasher comes in. Recently I have made another dehasher that can dehash any 3 digits with Java in about 40 seconds. So say your were to store all your numbers as hashes and needed to find the original number, a dehasher could be handy there.

Looks like I might just embed the videos in my mediawiki cms but I have just uploaded the latest video at http://syntax.cwarn23.info/media/new.html
Took 24 hours to upload and I've improved the quality but haven't checked the entire video for the blank out due to it's size. So if anybody would like to comment on it continue.

I'm only guessing here but wouldn't for better backwards compatibility with the cplusplus tag be as simple as making another language template?

oh well i only "hash" passwords. theres nothing else o my site that needs encrypting

I was meaning that in the future todays hash functions will eventually be used as encryption functions as they would in the future easily be decrypted. But the technology is till to come in many many years so most people don't worry about that part of future security unlike myself who secures every piece by future standards.

I agree that for new users it has for sure changed for the better but there are things that can be done to make things easier for the more experienced users. I believe that the solution to this is not changing quote/code tags but instead adding a new tag which will simulate the old code tag and possibly with a few minor differences for the better depending on what the community thinks. This new tag would basically be just to set text in monospacing which some replies require and the ability the have bbcode inside that tag. That is how I would solve the problem so what does the community think.

However, using code tags for something outside of code to achieve a visual effect as a result of the current way code tags happen to be handled cannot ever be guaranteed in the future. It is almost like exploiting the current system to do something it isn't designed to do ... it cannot be guaranteed in future versions.

Oh ... my post above is in response to this thread: http://www.daniweb.com/forums/thread235826.html

Do you have Optus cable in your area, it is way faster and cheaper that Bigpond?

I'm not sure what cabling there is at my location although I'm guessing there is little fiber optics but I heard most companies are only cheap in the states city cbd and I don't exactly live in 100 meters of the states internet hub. So that makes the plans so expensive and so slow. O' well. Another 5 years and Telstra will probably no longer exist due to the governments new cabling crushing their services quality.

If you have a table with a VARCHAR field, you can often improve search performance on it by changing the field to the CHAR type.

So is the char field type faster than text field type? Because that's what I really need to know although it's a bugga it will consume more space for faster performance.

I will give it a try and just in case I need to know, what do I do if my string length exceeds 255. Also does the string length effect the storage requirements as in does this make all rows have equal storage size? Thanks for the great helps so far! I'll be back tomorrow.

no im not sure i follow this very well. i dont think that its too hard to hack right now. but its illegal and people shouldnt do it just because. theyh could go to jeal etc..

It isn't illegal to dehash a hash unless you intend to use the crack for stealing passwords etc. So if for example you wanted to encode data and decode it using hashes that is not illegal. It is only illegal once you start stealing peoples passwords and one day a hash function on it's own will be very useless unless additional heavy security measures are taken.

Then for the 150 you used, does that specify the string length? If so then is it possible to have a variable string length where different rows have different lengths?

Newcastle - Australia
with Telstra i get 1.5MB/s down and 256kB/s up

WTF, that can't be right with Telstra. Their speeds are slower than what they advertise. I'm with Telstra and although their plan says 256kbps I only receive 25kbps down and 5kbps up. So looks like I'm the slowest one in the world even though I have broadband with Telstra Bigpond on one of their best plans. Can't wait till the government lays out those new cables then my Internet will be 100 times faster.

If you are looking for a security camera then use the below search term:

intitle:"Live View Axis"

Found a shop robbery on one of those cameras once and saw the footage again on TV lol.

Try this.

$query = 'SELECT * FROM `administrator` WHERE `'.mysql_real_escape_string($_POST['searchby']).'` LIKE  "%'.mysql_real_escape_string($_POST['query']).'%"';
mysql_query($query) or die('SQL Syntax Error - query was: <u>'.$query.'</u><hr>'.mysql_error());

Also with the above code it should have a pretty good debugging error if it fails. So run the above script and tell me what the new error is if any.

im pretty sure that is ok o use just sha1 being its a forty char long encryption.

I wonder what the world will be like in a few years time when that 4TB cd comes out where TB's of diskspace can be stored on just a few disks. So it would be possible to make to have a cd collection containing compressed dehashing data to the 7 digits. That's only the near future as in a few years. In maybe 15 years we may be able to store 15 digits on server farms during the time when a cd holds 23PB (petabytes) and each harddrive in the server farm contains 256EB (ExaBytes = 1024^6 bytes). What is your advice on preventing serverfarms dehashing where a single computer can hold 256EB and there could be hundreds of computers on a hackers personal server farm. Well Google will need somewhere to store all of those youtube videos in the future. That is when the world goes into crises which I am already thinking about preventing today. So my advice, don't wait till the year 10,000 for the millennium bug. Fix it right away.

one time i made a password encryption with pure php it went like this:
$password = sha1($password);
$password = md5($password);
$password = ENCRYPTED!

That's the kind of stuff I was talking about except I would recommend using the md5 or md4 algorithms as I have read reports that they don't always produce the same md4/md5 hash every time. It is a bug in the algorithm and therefore the md4 and md5 algorithms should be ignored.;) But other than that, great way of explaining what I was talking about earlier on.

How little you know of what actually goes into being a moderator here.

Is that a question or statement? If it's a question then my answer is that I could only guess the enormous effort for preventing spam and keeping things in order. So us members know very little of what happens behind the scenes and can only guess the great efforts the moderators and administrators have put into daniweb.

I will have to macgyver a login tutorial which reminds me I need to upload that other video tutorial tonight. Hope that helps.

This thread just has no direct answer so I shall help explain to Bob

Just a technical question on what is legal and what is not. I buy a printer, lets say a cannon, and after a while the black ink runs out, can I legally refill the cartridge as I bought it and it is mine?

From my understanding it is ok to fill the ink cartage yourself if you have a legal supply of ink however then the manufacture will nolonger having anything to do with you. In other words no support, no warranty, no guaranteed replacement printer etc. So unlike the cyberworld for most things in the real world are actually your responsibility if they are your property. So you can do just about anything that is your property as long as it's not part of the cyberworld or under terms of an agreement. And as for the printer, if you discard the warranty and the support then there is no agreement meaning you can do what you want with it although you couldn't resell it due to the issue of the manufacture did the majority of the designing of the printer which comes under another contract/agreement.

As far as I am aware that is how it works or at least in Australia and perhaps searching on the internet through law support websites for your country may help.

It wouldn't let me fit more than 10 names in the poll.

It's a bugga having that limit in the poll system. IMO, it would be better to have a limit of something like 16 because people are always saying they can't fit more then 10 options or at least whenever I vote. As for my vote I chose digital-ether as I have had a few nice discussions with digital-ether and learned a lot. If I could have a second vote I would choose peter_budo as I've received a bit of positive reputation from him. Nice idea for a poll though.

Well basically on my first attempt with I might try a similar approach again was a table of 4 columns just plain text type (not varchar). They all have variable length and I can never seem to get varchar() to work with the number I put in the bracket in phpmyadmin. I think that number might represent the length but I have variable length. Also the length of each cell never exceeds 90 characters. The basic mysql statement I use is as follows:

SELECT * FROM `table` WHERE `col1`="somevalue"

Just note that I don't always use the characters on the keyboard for the "somevalue" because it is encrypted to use most of the ansci table.

Also I'm testing on a computer with 4GB of ram and I did the math turns out my database failed at around 150 thousand rows. So do you have any ideas on what I should do or what how to set the columns to something better if needed?
Thanks.

Today daniweb seems to be much faster so must have been the newsletter. I never though the newsletter would take many recourses until you pointed it out because now that I think about it, half a million emails would require a lot of cpu. At least it's only a once in a blue moon event. :)

Is it just me or is daniweb hard to reach latley? Today I've been bumped off daniweb as the site froze and wouldn't respond and to site has sometimes been slow to respond when working. The first time this happened there was just a white page then eventually a message came back saying "daniweb is very busy at the moment please try again in a little bit". Then a few hours later some of the pages took ages to load although they eventually loaded. Is there something going on because this is rather annoying.:'(

Arr - ain't code tags meant to be used for code. As for the question assuming it's not code, php has a cool function called mysql_query(). With this function it is possible to insert and retrieve data from a database and to use it as something like a xls file, you could simply display the inserted data to the browser. Then when you get the user to download that file lapresto you have a downloaded xls file.

I shall put it plain and simple. While it is easily possible to loop through part of an array instead of the mysql result with pegination, an array with a trillion results will crash the server just like a reverse hash lookup table. Imagine storing a trillion results in an array and only looping through the required section - not possible unless you had a super-computer with a Petabyte of ram. Anyways, if you still are convinced you want to loop through an array then the following is an example of how.

<?php
//some array called $arr created above
for ($i=$start;$i<=$end;$i++) {
    //regular pegination code in here.
    //below is an example
    echo "<a href=\"index.php?page=$i\">$i</a><br>";
    }
echo $arr[$_GET['page']];

It is more like the best 3 search engines which include Google, Bing and Yahoo. The reason, they hold the greatest market share with Google being the strongest and I think Bing might be the weakest in the market share.

Then how many rows do you have and how much cpu? In each of my tables is only 4 text columns and one int column. Also the word NULL occurs as the value most of the time with my current structure if that makes any difference.

So I have 2.66GHz dual core with millions of rows. What are your specs for cpu and num of rows in your large database?

Wow, there is a bug in the quote reply, check the quote in my previous post.

One way it was done ages ago elseweb was (code), (quote), and (syntax). The syntax tags were used for the "fancy" code tags. Quote in monospace to me would look stupid.

I agree there but it would be nice if we could at option make regular text monospaced without giving it a background color and making boldness an option. Below was my suggestion to a solution for non-code that needs to be monospaced-

test first line
testing another line

And the above would produce the below but in monospacing:

test first line
testing another line

If someone would comment on adding that bbcode tag which has no background color.

but I can't seem to figure out why it is periodically doing this on-and-off

Perhaps it's part of the update process where when the data is being updated in the database, first the new names are being added to the database then a person downloads a copy of the list of names and after that deleted from the database is the old names. Just a theory of the duplicate names but that would be my guess.
