I have personally built a reprap and mendel, not bad for 3d printing but I need to calibrate it once in a while to get it to print well. Fans in your room will affect the plastic build too, so make sure you keep the room air condition/wind/temperature in a "stable state".

Thanks for your prompt response. I'm quite positive that the one bounty I received was for #29 and followed up on #31. The reason why I remembered this is because it was one of the first few BTC I received, thanks for that! Then, I spent more time debugging the site and posted more bug report. Btcx was busy since and I did not hear back from him. Now that I know the site is still in progress, I will try and report more bugs.

Since those bugs posted was found quite some time ago, I'm not sure if it has been fixed already but I'm sure I have tried many times to find and was able to reproduce the bug that time.

I have just pm you my btc address, you may send my bounty there, thanks again.

Hi, can you please send my bounty reward to my btc address? 
I only received my first reward on #29 and #31
I have posted several other bugs report at #33 #35 #38 and btcx acknowledge the find on #34 but he went to bitcoin meeting and was out of contact since.

Dargo, I see that you are in charge of this now, should I send you my btc address or you guys have it on file? Thank you.

Thanks, I hope you keep your word and just end with your period there. Please don't continue this and just take care of your own thread instead of posting over people's thread to advertise yourself. I do appreciate your cooperation. Thanks.

mah87, nice try in trying to get people to buy from you  
If you have not contacted me at all, don't go around and start calling scam in hope to lure traffic to your end.
Try and play fairly. If you can provide a proof of our conversation and how I am trying to scam, please do so. Good luck.

Thank you. It was nice dealing with you too. Fast and quick once we get to know each other 
The warning on my profile is posted by a scammer. He got reported and the untrusted feedback from him is now removed by bitcointalk admin.
Let me know if you need more btc. Thanks!

Thanks for the notice, it will help other forum members from being scammed.
I also had another known scammer (D35TR0Y3R) who post in my thread just before. I reported and the mod remove his thread from here; however, his negative feedback still remains in my trust profile. Is there a way to remove this?

Thanks for your support. I don't mind if people copy my titles, I can't stop them from doing it.
Just dealt with blacksterchrome
Great communication and thanks for trusting me with your ripples. Please leave me feedback when you have time. Thank you.

Hello, I know there are some threads here and there to buy your ripples and you can sell your ripples at other exchangers, but if you want quick, smooth transaction. You can sell your ripples to me, I need some ripples for testing purposes. If you have not dealt with me before, we can do escrow with John k if you wish.

Not sure if it will go down that fast within an hour. If it is down for half a day or something, it would have cause more panic selling and the price may go below $100. Looks like some attackers are taking advantage of this, attack site, cause panic, , buy low, sell high, profit.

I am a web developer and I actually had one planned up. However, I put the project on hold because I'm thinking it could lead to a lot of "self promotion", people submitting their ad/affiliate/spam site that doesn't have much value to user. They simply need to accept bitcoin payment so they can add themselves to the list. The moderation part need a lot of work and I'm still deciding the best way to do it.

No problem, hope everything is going fine there. Let me know when you have gone through post #35.

* Found another 2 bugs (related to Two-Factor Authentication).

- Bug 1:
To reproduce - Set a two-factor authentication for login using a password. Log out and try login in without the authentication, you will not be able to login. Now try logging in with the authentication. After logged in, you will see on top right under your username - 1 bad login since... If you click on that, the grey background shows up weirdly, it is overlapping the top menu bar.
To fix it - This is a css issue. The padding you have as
#user-menu .dropdown-toggle {
    padding: 14px 8px;
}
did not account for the extra bad login line so the grey background overlaps the top menu bar. To fix this, simply add a max-height: 38px; or code the background differently.

- Bug 2:
To reproduce -  Setup a  two-factor authentication. Will see an extra space typo in email.
To fix it - fix "You have updated your  two-factor setting on your account.  The IP recorded was " the extra space after "You have updated your" and the space before "The IP recorded. The same goes for "You have updated your  secret two-factor setting", "You have updated your  trade two-factor setting" etc

Found another 2 bugs. Had these two bugs before and spent a long time to find out how to reproduce it. Let me know if you need more info. You have my btc address 

Bug 1
To reproduce: When you have low in USD fund, buy BTC that is higher than your fund and switch the option to buy at market rate.
Bug: The system will let you proceed anyway and created an order id, however when you check the order, it is cancelled right away. You may check Order OV6OYZ-JSLCK-3DXH6O
Proposed solution: System should not waste the resource to create id if the user clearly does not have fund to complete the order. System can check the current market rate and do a calculation, compare it against user's fund and decide if a new order should be created.

Bug 2
To reproduce: From bug 1, after the system created the ID and a successful green message pop up and disappear. Try to buy btc using market or limit (set your own or auto).
Bug: You will see if you have insufficient fund, the system will show a pink box with no text it there, it is just an empty pink error box. If you navigate to another link, or if you log out and log in again. You will not be able to see the error message. Also, when you try to sell BTC after producing this bug, you will not see a success message, you will just see the pink box.
Proposed solution: Fix bug 1 and go from there. Looks like some id got missing and the message could not be displayed into the correct div.

Thanks. I have pm you by bitcoin address, please send the reward there.

I have mess around with a site a little and believe I may have found something and crashed the login module?

To reproduce the bug, using Account 1, under settings, change the email to the email of account 2. Before activating it, cancel the email change using the button provided under the settings page. Then change the email to email of account 2 again.

Bug: You will see that under settings of account 1, the username is blank and the email disappeared too. When I tried to logout, I was unable to. The error message was "Failed to logout".

I tried using another browser to login account 1 and account 2, both are showing:

500

Application Error

An application error has occurred.

So, I believed I may have caused that to happen because I tried it right away.

Proposed solution: I believed that when a user set to change their email and cancel, the system did not actually cancel the request. It just hides the confirmation (count down) dialog box but still wait for 8 hours before it actually expires. So, when user request for another email change, something weird happen.

Let me know if you need more info. Thanks.

That could be why. But there could be a potential issue.

1) User who forgot their password before they activate are stuck.
Workaround:
When they provide the right username & password combination but wrong confirmation code, have the error message such as
- error message: Invalid username and password combination, click here to reset your password or wait x hours to register again.
- solution: Make it posibble to reset password before activation. Gives clear instruction how to proceed if you do not offer password reset before activation. (i.e, let them know how long to wait before they can register using same email & username)

When they provide invalid or expired confirmation code, have the error message such as
- error message: Invalid activation key or signup has expired. You may register using the same email again.
- solution: Let them know more clearly what can they do in this case. If your database still store their info, offer a link to resend new activation code. If not, let them know they should register again.

In my case, I'm not sure if I have my username/password combination incorrect. I have not activated the account yet and when I tried to sign in, I get the following error:
Invalid activation key or signup has expired.
I don't think the signup expired yet since it's only been a short while. I also got the activation code from email. So, I think I should havve wrong credential info. The system should be clear on this.

Please let me know how can I proceed now. Thanks!

1) Not receiving Forgot Username reminder email.
2) Not receiving Forgot Password reset email.

Checked spam folder, was not there. Did receive the activation email during signup.
Email Platform: Gmail


P.S: Please trigger a reset password email to me. Thanks.

Think of it this way, you are "part of a bank" and you won't be able to get an accurate balance of your wallet because you have not received the transaction block yet. The wallet synchronize all the transaction happening when bitcoin started, so it will take time for it to catch up to your recent transaction.

I understand what you are trying to express. You are saying that we can use this calculation to solve something meaningful that would be beneficial to the society, something like finding large prime number, or that "special" number that can be used for enhancing cryptography securities, encryption and so on. They may not be a way now but people may come up with something in the future.

You can do it through exchangezone, they currently don't have fees imposed but may require photo id validation before you can start trading.
