901  Economy / Gambling / Re: This is why you shouldn't use martingale on: April 23, 2014, 12:05:00 AM
Has anyone successfully used a half martingale approach to their gambling? You take the martingale and cut it in half effectively doubling your longevity.

Not that I know of. Doesn't really work out because most people don't have enough money (and the house limit) to afford really long and unlucky streaks. The only way is to possibly have a 1 satoshi starting bet which would mean you'd survive something like ~ 23 losses in a row with a 1+ BTC deposit. But it would take you an eternity to actually make much profit.
902  Bitcoin / Bitcoin Discussion / Re: Which Bitcoin Client do you use and why ? on: April 22, 2014, 11:41:45 PM
Multibit vs. Electrum...which are you guys preferring?  Any major reasons? 

Electrum - primarily for the fact that it can sign transactions offline so I can use it as my cold storage software rather than Armory which means I would have to download the whole blockchain on the broadcasting computer. Multibit AFAIK doesn't offer the option of signing transactions offline.
903  Bitcoin / Bitcoin Discussion / Re: Why won't Riot games accept Bitcoin on: April 22, 2014, 11:34:51 PM
Put yourself in a 15 year old's position - you have no credit card so can't pay for RP with Paypal or Moneybookers, however you do have some cash and could buy some Bitcoin. Send to Riot, get the RP, everyone's happy.

I don't know about you - but where would a 15 yr old kid go buy some BTC with cash, kids at that age can't even drive so I'm pretty sure their parents would be more willing to either pay for it with their CC or just buy them an RP card. If anything it'd be easier for someone to buy a card than buy BTC and just use that. Anyways, not to mention - much of Riot's userbase doesn't know/use Bitcoin so it wouldn't really be adding anything for them.
904  Bitcoin / Electrum / Re: [ANNOUNCE] Electrum - Lightweight Bitcoin Client on: April 22, 2014, 10:26:12 AM
Can anyone help me out here... I have an Electrum wallet on Debian (1.7.3) and today it just refused to connect to any sever, is this version obsolete now or something?

As far as I know this version is completely up to date at the moment. Have you given it time to generate all the cert files?
905  Economy / Services / Re: Looking for someone to help me set up oclvanitygen. on: April 22, 2014, 09:10:53 AM
so just copy and paste then? I've also got a crash when i use oclvanitygen.exe -i -P 04FA53359D811463B6698E7AB54BF228E016497A960078B...B1EFBF82CC7E741A2FC36B17 1(prefix)

First off, it appears to me that you're not using sam7's version but rather the one 'Lifeboat' oclvanitygen edition. My advice would be to try sam7's from the link I posted and see if that does anything. How are the drivers for your GPU - are they up to date?
906  Alternate cryptocurrencies / Altcoin Discussion / Re: New Coin Concept: proof of work in fix time (defeating ASIC) on: April 22, 2014, 08:58:57 AM
Ideas are cheap. I keep seeing more and more alt-coins with different hash algorithms in the hope of defeating ASIC.

If I may ask, what exactly are you trying to achieve by negating the advantages that ASIC mining has over CPU/GPU mining? And in what way would that benefit Bitcoin?
907  Economy / Service Announcements / Re: [ANN] bitaddress.org Safe JavaScript Bitcoin address/private key on: April 22, 2014, 08:53:10 AM
I have a noob question:

When I save the website to a file and open that file in my browser in offline mode, I don't see the "initial mouse screen" anymore. It goes straight to the main website. Why?

However, I still get the green dots when I mouse move on the regular page. But I get no initial page that prompts me to move the mouse.

What should I do about this?

Did you save the file as 'Webpage HTML only' and if so which browser are you using?

Compressed keys take up less space in the blockchain, therefore the transaction can be smaller. There is a detailed explanation on how this works.

As an example, you have a bunch of unspent outputs on a bunch of different non-compressed addresses, which if you send them all in a transaction will take up 2000 bytes. Had those exact same unspent outputs been on compressed addresses, the transaction size would be about half the size, or 1000 bytes.

Transaction fees are based on the size of the transaction, not on the amount.

More info in the following links:
https://www.google.com.ph/search?q=compressed+bitcoin+keys
http://bitcoin.stackexchange.com/questions/3059/what-is-a-compressed-bitcoin-key
https://bitcointalk.org/index.php?topic=129652

Thanks, I've been using compressed keys for a while on that basis but I wasn't exactly too sure whether it was right. On the topic of fees (a bit off-topic again) have they been reduced to 0.00001 from 0.0001 and if so has this change been accepted by both the nodes and the miners?
908  Economy / Services / Re: Looking for someone to help me set up oclvanitygen. on: April 22, 2014, 08:50:36 AM
well firstly, i have a hd 6950 and i know it's only using the CPU because it's stuck at a speed of 600Kkeys/sec instead of 20mkeys per sec

Well not to be rude, but are you sure you are using oclvanitygen from the package created by sam7 (https://bitcointalk.org/index.php?topic=25804)? Make sure it's oclvanitygen (not vanitygen and not oclvanityminer).

And have you made sure to use this format?

Code:
$ ./vanitygen -P 041d2e778ae6d9124736df131cd22d3a2483f336c55156d87a84c4bdc6d89f8518e33de85ae0f907a7128c476281bc8cc7742b43a54ccc2c7824dc4c4a438a7fbc 1Boat
909  Economy / Services / Re: Looking for someone to help me set up oclvanitygen. on: April 22, 2014, 08:19:05 AM
I have a public key, and oclvanitygen does not seem to use my gpu, only my CPU to look for the keys

What GPU do you have and how do you know it's only using the CPU?
910  Economy / Services / Re: Looking for someone to help me set up oclvanitygen. on: April 22, 2014, 07:19:38 AM
Hello, I am looking for someone to help troubleshoot my computer and start mining for vanity addresses.

What exactly is the problem? Are you mining vanity addresses for yourself or mining for a pool?
911  Economy / Scam Accusations / Re: 999Dice is a scam on: April 22, 2014, 07:15:49 AM
I have never been scammed from the site and I have been paid out when I won. Not sure what else I can say. I am up .11 BTC on the site. Granted that's not much but no reason for me to bash the site. I actually support the site and as far as previous claims, I cannot dispute that as I am new here, but if you would point me to links then I will go on my way and read them. If there is a connection and someone scammed someone then shame on them.

The admin at the site has answered all of the questions I have asked. I can't say anything negative at all about 999dice.

Your word doesn't really mean much considering that you are a new account (literally created today) which could very easily be a sockpuppet for the 999dice admin. Unless the admin would be willing to come back and properly address the issues raised, there is no reason to believe that the status quo has changed and that suddenly the site is legitimate.
912  Economy / Trading Discussion / Re: Transferring bitcoins from blockchain to paypal on: April 22, 2014, 07:08:10 AM
You'd either have to trade your BTC for PP (be careful there are many scammers on this site so please only work with well known & trusted members) or you could use something like localbitcoins to trade with someone for a bank transfer which you could then add to your PP. But if you're looking for a direct way from BTC to PP you're not going to find it - PP is completely against BTC and at the moment has no plans to support it in any way.
913  Other / Off-topic / Re: heartbleed bug on: April 22, 2014, 07:04:05 AM
The heartbleed bug isn't exactly easy to understand (from a technical perspective) but in layman's terms it was a flaw in OpenSSL (which is used widely) that enabled attackers to gain access to 64kB of memory with each 'heartbeat' which allowed theft of servers' private keys and users' session cookies and passwords. Hence the suggestion to change your password - as it may be compromised.
914  Economy / Digital goods / Re: How much these domain names worth on: April 22, 2014, 06:55:59 AM
Not to repeat the same things as everyone else - but those domains are also extremely niche (in that only bitcoin'ers will use them) and given that there are probably better domain names to suit a business/startup than what you have.
915  Economy / Service Announcements / Re: [ANN] bitaddress.org Safe JavaScript Bitcoin address/private key on: April 22, 2014, 06:53:36 AM
I just went there, just now.

bitaddress.org

After the mouse and keyboard random input, the easiest way to generate compressed keys is to go to the Bulk Wallet tab, and click on Compressed Addresses, then hit Generate.

Compressed private keys begin with the letters K or L.

Personally, I prefer using vanitygen to create a lot of keys, its much faster than the javascript version.

Ah ok, thanks. A bit off-topic but I've heard that compressed keys may lead to smaller tx sizes and hence helps to reduce possible fees and blockchain block? Is this true and if so why?
916  Economy / Service Announcements / Re: [ANN] bitaddress.org Safe JavaScript Bitcoin address/private key on: April 22, 2014, 06:25:54 AM
Sorry if this has been asked before - but is this capable of producing compressed private keys and if so how would one go about it?
917  Economy / Service Discussion / Re: Vault of Satoshi Launches Full Proof of Solvency (Not Just an Audit) on: April 22, 2014, 12:57:59 AM
Of course it does.

1 cold wallet = Only takes one security incident, one private key stolen, all funds gone.
10 cold wallets = Needs 10 security incidents to lose everything, otherwise one breach only loses 10%.

Naturally the 10 cold wallets need to be stored separately and in different manners in order to be effective.

Same goes with the hot wallet.  One flaw in the app or servers and the entire thing could be drained.  Multiple hot wallets on separate servers with very different access methods will make it much more difficult for a hacker to take all of the hot balance.  More likely they'd go for the first one they could get and after that Vault would know and shut the rest down.

The thing is - if it truly is an air gapped cold storage system it is extremely difficult for someone to actual get hold of the private keys. Setting up 10 different cold storage systems is a lot of effort and wouldn't really achieve that much as if you had a flaw in one you'd have that same flaw in all of them.

The whole purpose of a hot wallet is not to have all your coins in there so that if it is stolen it isn't such a big deal. Trust me - having many different hot wallets which different access methods is not exactly easy to manage nor is it that cost effective. Honestly, they'd be better off getting lots of pen-testing done and keeping admin accounts away rather than trying to split up their wallets.
918  Other / Beginners & Help / Re: Is there any BTC bank? on: April 21, 2014, 12:31:05 PM
Why would there be a bank... Is it really that hard to secure your wallet with a password of sufficient entropy that you can remember? Not to mention, a conventional bank would ruin the anonymity part of Bitcoin and  much of the decentralization purpose.
919  Economy / Economics / Re: What happens to the price if mass acceptance is not achieved? on: April 21, 2014, 12:25:45 PM
First off there is no black and white definition of 'mass acceptance', how will anyone even know when we have/have not achieved 'mass acceptance'? On the assumption that somehow everyone is in agreement as to what defines mass acceptance, I'd say we attain some degree of stability with the possibility of climbing higher on the basis of hope for greater acceptance and merchant/consumer integration.
920  Bitcoin / Bitcoin Technical Support / Re: Prove offline transactions to customers? on: April 21, 2014, 12:21:02 PM
I'm trying to develop a bitcoin app in which a customer will send me some funds, I will then move them around from one account to another and send it back to them.
To save on transaction fees I want to us the 'move' command for in-house transfers but when I do so I'm only provided with a True or False value rather than a transaction id.

My question is - When the funds are moved will this be this visible in the blockchain (blockchain.info in particular) and if not then how can I prove to my customers that the 'movements' took place and I'm not just lying to them?

Thanks in advance for any input Smiley

Unless I'm deeply mistaken the only way you can move funds between different addresses is to broadcast a transaction and have it confirmed in a block like everyone else (meaning you can't avoid fees unfortunately). As addresses are considered separate and your wallet is simply a conglomeration of addresses I don't think there is a function to move BTC between addresses in the same wallet. Obviously if you have a standard tx it will be visible on any blockchain explorer.
