The shorter the rounds (the higher the pool hash rate), the lower the hash rate threshold where you will make more using PPS than Proportional.
The profit doesn't depends on round length at all.

Sure it does.  If a low hash rate worker can create only a few shares during a given round, then that means the last share worked on in any given round will likely be discarded due to long polling or be stale when submitted and that last share is proportionately a larger amount of their worker work output.  When rounds get short enough on average that a worker can't create many shares in a round, then a significant percentage of a worker's total work [on average] will be wasted when a round ends.  With faster hash rates, the amount of work lost to working on a stale share [which LP helps reduce] will be much smaller as a total percentage of all the worker's work.  Essentially, it is because a share is a quantum amount of work [you don't get paid for 0.5 shares ... there is no such thing and no way to submit it anyway when the round ends].  It is clear that for PPS to pay better over time, the difference would have to be close to 7% [difference between proportional fees and PPS fees].   That would probably have to be a pretty low hash rate per worker, but as difficulty increases, the number of shares accepted will decrease and this will drive up the threshold.

A scenario that can be easily tested is to run many CPU miners in parallel and such that their cumulative hash rate is the same as a single solid GPU worker.  See which one gets paid more using proportional.  In a large pool, it will be a notable difference.

If it were possible to submit partial shares when a round ends and not have them be invalid, then the quantum effect would not occur.

A simple example.  Suppose that a nice slow worker averages 5 shares during an average round.  It should be clear that when a round end, the worker is working on the sixth share on average and never gets paid for that work.  So, that would be on average approximately a 10% loss (average share loss would be half a share with long polling working perfectly) and 0.5 / 5 shares accepted is 10%.  Clearly, if a miner on average produces several thousand shares in a given round, then the effect is negligible.

To me, that says, low hash rate workers [even if one has dozens of them running parallel] will do better with PPS or using a smaller pool.  Like I said, I am not sure what that quantum threshold [my name for it] is, but it should be relatively easy to calculate by the people running their workers [they know that their hash rate is fairly constant per miner and then it is simply a matter of math based on the average number of shares submitted versus the average round length, which is a function of pool hash rate over time].

I am sure this could be explained more easily by somebody less wordy than myself, but I tried anyway.

If you're going to require emails to be sent can you please fix your code to recognize the emalis you have stored with + in them instead just getting "Mail_sending_failed"? I can't get my funds out. Not cool man.
At least I assume this is the problem since you don't display the + anywhere you display the email and strip it out of my miner logins.
Edit: Oh, I see it's not implemented yet according to the last page. Can you make sure emails with + in them will work please? I have a bad feeling the wont given the state of your other code.
Yes, the plus sign is stripped from login names. I tried to enable it, but that caused problems for existing users.
Don't worry about your funds, I will provide a way even for those with invalid e-mails.

Will your mailserver receive a message with "+" stripped from address ?

I setup an alias so it would, yes.

Just was able to update, so, good show.

I entered in a new bitcoin address then hit save, and confirmed it via email.

The address box is still blank.  Is this normal???

I'm not getting the email, I assume it's ignoring the + sign.
Yes, it does. I'll try fix it soon.
Open the form one more time, enter your address, click "Save" then send me a PM with your login and your new bitcoin address - i'll test it and send you the e-mail.

So does this mean that everyone needs to confirm there bitcoin address and do the email confirmation thing?
Yes, you can set the same address as before (or a new one), but you need to confirm it via the link in e-mail mesage. Sorry for this, but I need it for your own safety so noone except you can take your money.

No. Can you please try again and if it's not working - send me a PM with your login ?

Hi. I'm new to the pool as I just started some days ago.
First of all, thanks to keep safe the accounts. I have the same problem as when I enter new address I don´t receive any email and can´t do confirmation. Should I send you a PM?
Regards.

I have two deepbit accounts.The new security solution worked fine for the first. Not working at all for the second. Tried with firefox and internet explorer, emptied cache, clicked on confirm  link from e-mail client and tried to paste it to the address field in the browser, the adress to which funds are to be sent is still blank. Probably just a minor flaw in the code that Tycho made.

But people, be patient. Tycho has responded to this security breach issue very promptly, and he's attempting to fix it, if he was an ass he could probably just have ignored it all. Other pool owners would perhaps just have said: "Sorry, it is your responsibility to keep a strong password".

I sent Tycho an e-mail regarding the problems with my account, and also suggest that he implements https when having the time. http-passwords are sent unencrypted, so anyone listenting to your network traffic can see it. However making e-mail verifications for changing the workers-address will likely prevent anyone having access to your account from changing the recieving bitcoin address.

Please consider enabling TLS for the login/registration page. This would be a nice increase in security. Enabling HTTPS will help to prevent (but not completely stop) others from "sniffing" traffic. At least the login credentials would not be in clear text. As a network security admin I can tell you it is trivial to capture packets on a local network. Some people may not have the ability to be on a private network when logging into their account. If you sign in using a school network, the network at your place of work, or from the local coffee shop you could be exposing information that can be used to gain access to your account. I can only think of good reasons to enable TLS and only bad ones for not.

Cheers.

Tycho, very good decision to give the stolen BTCs to the victims!
another good decision is the email confirmation for changing the wallet address
 and a future one will be to implement https like mtgox Wink
well done mate, that is why your pool is the best Wink

Another thing that came to mind,
since logout is not implemented to site (at least easily)
then if someone left the pc without performing logout and someone else get inside...
you understand, no hacking is needed Wink
