Missed it by that much.

Seriously, that's a great raffle - thanks to Matthew for the prize and DeepC for the algorithm. 

I'd be up for another....

Well this was fun.

I'm emailing the winner right now with instructions on how to earn his BFL single by completing some simple offers online and answering some surveys.
Hehe.  You're so mean!

The only issue is the "remainder" greater than the max multiple.

10 hex digits = 16^10 = 1099511627776

1099511627776 / 40270 = 27303492.12  (that last 0.12 is unfair)

So max valid random number is 40270 * 27303492 = 1099511622840

Matt a "fix" is simple and fair.

If the value of last 10 digits of the block hash is > 1099511622840 then it is a "no-go" and you use the next block.

Don't worry the odds of that happening are very small.  Only 1099511622841 to 1099511627776 are "bad".  4936 unfair numbers out of 1099511627776 or 0.0000004%

I have updated my raffle ticket picker here: http://we.lovebitco.in/raffle.html. It will now alert you if the hash is greater than the last modulo interval with a full number of tickets (however you would describe that). Just so everyone knows they have an absolutely equal chance of winning.

Feel free to pore over the javascript source and try to break it or find any type of unfair calculation. As an example, in this raffle (with tickets 0-40269), the highest hash without error is FFFFFFECB7, which gives #40269 as winner; FFFFFFECB8 or higher gives an error.

Large hashes near the maximum are also only a problem if 0x10000000000h is not evenly divisible by the number of tickets. For example, with 65536 tickets (0x010000h), a hash of FFFFFFFFFF is still valid.

BTW, even with a raffle happening every block, this would likely never happen in your lifetime...

You should add a thing to sha256 a text field.  I liked having the list of emails be hashes.

I didn't like that, it becomes easier for a raffle operator to disguise his own fake entries (instead of showing forum user names, etc., which allows us to intuit that every ticket purchase in the list is legitimate).

Not sure that clear text email entries help that much. One can easily create a series of different email addresses that really have the same owner.

Done. Works for emails, I'm not doing any input validation, so you can probably confuse it by pasting a bunch of junk into the input field.

Don't forget to lower case the input for those who don't realise that upper/lower case is not relevant in email addresses Smiley

People just need to remember how they typed their email address. You can not alter the case in email addresses, as they can be case-sensitive.

rfc5321 says:
The local-part of a mailbox MUST BE treated as case sensitive. Therefore, SMTP implementations MUST take care to preserve the case of mailbox local-parts.  In particular, for some hosts, the user "smith" is different from the user "Smith".

If a user inputs inputs the domain part of an email address in upper case, then bit-pay should not accept the invalid domain, instead alerting the user that they are a retard.

LOL it took until 2008 for someone to realise that MS had messed that up in Exchange and write an RFC that was actually wrong?
I wonder how hard it is to delete an RFC that someone came up with.
... and why did anyone bother to agree to that Tongue

Do any mail servers except exchange do that "MUST BE"?
I'm pretty sure the majority of mail servers on the internet don't do that.

Edit: Ah - OK, I read that again.
The case is not relevant in the email address, it's just that computer accounts can have case sensitivity so a mail server that uses the front part of the address to determine the account name on the server may screw that up ...
Still, not a problem for anyone who uses the norm like e.g. virtusertable on sendmail.

If there's a difference between standards and how Microsoft does stuff, it is because Microsoft does stuff wrong.

Your mail server may send either kano or Kano or even KANO@ emails to your email box. My email server might send deepceleron@ and DeepCeleron@ to different mailboxes. Nothing along the line can mess with the case of the email address that you type in to email me, otherwise deepceleron might get DeepCeleron's email.
