Haven't you ever hired someone to do images or a website only to find later that they ripped off the images / the site ?

Check out http://www.devtome.com/doku.php?id=cpu_mining

So far is has been working pretty well and is surprisingly popular. It does not need powerful expensive machines even, a Raspberry Pi or a Beaglebone could do it nicely...

The form of "CPU mining" described at http://www.devtome.com/doku.php?id=cpu_mining is turning out to be surprisingly popular, maybe partly because it is not about how many zombies you have in your botnet nor even how many cores your machine has... (A Raspberry Pi would work just fine...)

Basically it is not about sheer power, especially not calculations that can be done by masses of parallel processors. Instead it is all about making decisions, handling branches and changes of situation, the kind of stuff CPUs, especially CPUs with a human behind them adjusting their tactics and strategies, are best at; so running a million zombies would take too much human intervention.

Well supposedly namecoin was never much use to start with because names were so cheap that basically everyone's name was already taken almost before anyone had heard of the thing?

Are there any usernames from this forum that weren't squatted, for example?

Though maybe the whole point of this "bug" was precisely to get to see what names were wanted then grab them?

Starting over doesn't seem likely to be helpful since squatters scripts will collide all over each other in the first few moments after the fix grabbing every name than anyone ever wanted...

Back when they were doing margins on margins maybe it seemed a potentially useful margin to be able to run six boards if that turned out to be what it would take to meet their target number of hashes per second per unit...

Are you conflating initial distribution of your currency with the ongoing and very not-profitable business of securing your currency?

Remember that mining is ultimately a race to the bottom, it is, by design, the type of business in which profit will be almost non-existent because if you try to remove something to take as profit you are crippling your own ability to compete with competitors who don't need as much profit or who have cheaper labour/power or whatever.

So first off, totalyl separate the matter of securing the blockchain from the matter of who gets how many of the currency in the first place.

You want something like ASIC for securing the coin, because securing the coin is damn close to zero profit, the only reason there are any transaction fees at all are not so that there will be profit to lure people into mining but more so that there will be a budget out of which people can try to secure the damn coin hopefully without so much parasitical freeloading, also known as profit-taking, that the parasites take so mcuh as what they consider their "entitlement" of "profit" that there is nothing left to actually secure the damn coin.

Mining is not meant to be profitable, it is meant to be feasible, that is, people who can get really good prices on power and parts and support and bandwidth should be able to "afford" to mine, hopefully without having to skip any meals to keep the miners running.

So just totally forget about mining as a source of income for anyone. Focus on who do the coins created originally get given out to originally.

For one thing you can then hopefully see that it would be better to give out actual bitcoins than to make up some new coin, because some new coin is less likely to have enough transaction fees going on to finance the securing of the blockchain. SO ideally you want a coin that, like bitcoin, already has lots of transactions going on, so that there is some hope that securing the chain can be doing not by giving way new coins created out of thin air but, rather, by people who want transactions done paying to have their transactions processed.

Giving away money is a totally separate concern. It should be none of the miners business who you give away your money to, who ever wants to give money to someone should simply pay their transaction fee like anyone else to have some of their money be transferred to someone else.

Maybe you would be best off using Ripple source code instead of Bitcoin as your basis to build from, because with RIpple type approach you do not have that insanely huge expense involved in securing your currency. YOu can simply print a hundred billion coins and give them away to anyone you wish, whether by having them solve captchas or give you blowjobs or however else you'd like to choose who to give the stuff to.

Well, that escalated quickly. But seriously, Who would give you their exact Order number and other private infos? After what BFL  did regarding forced refunds for too loudly voiced opinions?

No one's going to force refund anyone, you have my word, and I have never lied to anyone here. He is not a customer.

Careful, he will say you force refunded him just to smear your name, provide zero proof of this happening, and then the loonies on this thread will try to lynch you.

Since you did not quote anything of my last post regarding your inquiry I gather you were satisfied with it?

Sure, I have a feeling you didn't quote Sam's entire response though. (Sorry for nitpicking Smiley)
Of course I left some things out. His quote of the (copy pasted with huge letters) terms of service and bullshit regarding them reserving my place in the queue while I "funded" the remaining VAT and this little marvel:
"When looking at the entire picture of this order I find that there are no grounds for you to demand any form of compensation at all and as such we will not offer any form of compensation in this case."

Oh great you left out the part that this is just you, instead letting people imagine it is a general blanket thing applying to everyone. Nice trolling.

No one has confirmed a tracking number past a day 2 order yet. 

I have, my previous post. I am not day one nor day two, but paid on the 4th, and I got my tracking number now though its stage is only that the label has been printed the item is ready for UPS to go pick it up.

2331  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [DVC]DevCoin - Official Thread - Moderated on: October 14, 2013, 03:22:10 PM
Well to me GeistGeld is the most urgent one, as that cannot even run on a machine with less than 8 gigs of RAM. Plus, all of the merged coins except DeVCoin and NaMeCoin are pretty simple as they are pretty much cut-and-paste coins. So others would be quicker to do too so might as well be gotten out of the way first maybe. GRouPcoin and CoiLedCoin aren't even on an exchange at all yet, so worrying about DeVCoin potentially being dropped from an exchange that a lot of folks seem pretty sure is run by a repeat-offending scammer, while it is still on Vircurex and I think even on at least one other exchange, doesn't really seem all that urgent. At least DeVCoin is still on a merged mining pool, GRouPcoin might end up being dropped from the one merged mining pool that it is on if it does not get picked up by any exchanges.

So it does not really seem the most urgently in need of work right now. If I had any time to try to upgrade a coin I'd do GeistGeld because it is an even worse memory hog than I0Coin was. Then I'd maybe do CoiLedCoin, since maybe if it got updated one or more pools and/or exchanges might pick it up...

And yes Unthinkingbit is the developer, he offered bounties for help learning how to make the coin he wanted to make and that is how I got involved.

Mine is in the six hundreds and paid the 4th so I hope I will hear something about mine before you folk from the 20th and onward get yours...

2333  Alternate cryptocurrencies / Announcements (Altcoins) / Re: GRouPcoin on: October 14, 2013, 12:25:56 PM
Use I0Coin. It has the memory usage fixes all the merged mined coins need plus is based on quite recent bitcoin code. Its the only one that makes sense to use.

2334  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [DVC]DevCoin - Official Thread - Moderated on: October 14, 2013, 12:23:25 PM
I'd be up for offering some DVC towards a bounty to get the code fixed.  However, I don't really know what is wrong with it and I'm not a coder.  Who can help?

The code is based on bitcoin 0.3.  Right now, we are at bitcoin 0.8.  We need to catch up the code so it does not crash.

Ugh, that sounds like fun. Ok, I too will put in some DVC, 1 million of them, towards this bounty of updating the code.

I need some guidance I'm beginning to look at the src. Can I not just look at maybe taking a new snapshot from the latest say Namecoin which is also merge mined, or just take the latest bitcoin and add merge mining capabilities and change the settings to match devcoin settings instead of going in adding patches? Are there other specific devcoin patches (and or what reason)?

Does it make sense to essentially start the codebase from the fresh fork(either from nmc or btc), match the settings up and be done?

Jag

Use I0Coin as base. It is pointless to do an "update" without fixing the memory usage problem that all merged mined coins except I0Coin still have.

Probably one would want to work closely with Unthinkingbit too as there were lots of little gotchas all over the place, where costants were hard coded that have to change for DeVCoin due to DeVCoin being so wildly out of line with other coins in terms of how much a single coin is worth. Most clones don't really seem to care about the relatively minor changs in how much spammers really have to pay to spam a chain but with devcoins being a thousand times less valuable per coin than other coins those tiny fees become significant enough to need tuning to prevent spammers being able to afford a thousand times as many spam-transactions. Lots of little stuff like that.

Maybe start by making a "diff" between DeVCoin source code and the exact version of bitcoin we built it from, to see each and every little way in which bitcoin was changed to make devcoin... Then go make all those changes to the latest I0Coin...

2335  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [DVC]DevCoin - Official Thread - Moderated on: October 14, 2013, 12:15:16 PM
DeVCoin is not as different from other coins as NaMeCoin is, but it is way up there, it is NOT just a copy/paste clone with a couple of constants changed or even with a different algorithm for adjusting difficulty; it has the entire receiver files handling system and all the dividing up of the coins to the addresses listed in the receivers file, plus all the minumums and maximums and default fees for different things that cause fees and so on are also different.

2336  Alternate cryptocurrencies / Altcoin Discussion / Re: Ixcoin TODO on: October 14, 2013, 12:11:27 PM
Bitcoin itself did not have encrypted wallet back when Ixcoin was created.

The codebase to update from is the I0Coin code, because it would be stupid to upgrade without fixing the massive-RAM-use problem that all the merged coins except I0Coin still have.

2337  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [DVC]DevCoin - Official Thread - Moderated on: October 14, 2013, 12:05:35 AM
From the start the GUI would never mine because of some kind of problem with multithreading, maybe because the libcurl or whatever we use to go get the receiver files is not thread-safe or something, we never did figure out exactly why mining would not work, instead we simply disabled mining in the GUI version, you have to use the daemon to mine.

That is the only multithreading "issue" I know of; could it be that RS has been hacking at it trying to get mining to work in the GUI or something?

I have no problem with devcoind crashing, some other coins I have made wrappers for to fire them up again when they crash, I have never bothered with devcoind because it never crashes. So I don't know what version he is running, from where, but it sounds like it isn't the version I have been running.

I have been running BLT and AMU devices on Fedora Core 17 using cgminer 3.2.0 but even a fresh clone of the github repo, which builds as 3.5.0, does not work for my AMU devices. It detects my BLTs but not the AMUs. I for now I have had to go back to using the old 3.2.0.

(I even tried bfgminer again, but a git pull of that to get its latest code results in one that wont' detect my BLTs as well as not detecting  my AMUs so for me bfgminer is still looking less useful than cgminer because at least the ancient 3.2.0 of cgminer will run my eruptors and lancelots.

I would like to be able to update though. Does anyone know why more-recent versions than 3.2.0 do not work?
