You're right, I was curious whether it was just me you played the insane game of "pretend what they said is fallacious then when they explain why they're wrong call them an astroturfer".

It's not worth it reasoning with this guy. I had a very similar situation with this guy. I asked him "are you claiming X", which he said was a strawman, then refused to explain what he was claiming and called me a sockpuppet.

lappa··on FoldingCoin
>Actually non of the money goes towards protein folding, its the power of the folders that does. All of the FLDC (money) goes directly to those that fold.

What else could you possible think I meant when I said the money goes towards protein folding?

>Other blockchains require a lot of maintenance and patches, we do not. Almost no overhead

You have the Bitcoin blockchain as overhead and you have the security of the Bitcoin blockchain, however you have created a speculative asset that is Bitcoin plus a mandatory tax for protein folding.

lappa··on FoldingCoin
You didn't really address why you think the miners are there for a reason, you just asserted it.

Realistically, what you have done here is made a centralized currency in which you issue new coins for yourself then we trust you donate the coins to protein folding.

We can already donate to protein folding with Bitcoin so I don't see much use in making an altcoin that does it in a less useful way.

lappa··on FoldingCoin
Your lack of an IPO doesn't imply pump and dump. Making an altcoin that is deceptive and speculative.

"Mine Medicine, Not Hashes" implies that this is somehow useful for medicine. It really is just a pump and dump where a portion of the money goes to protein folding.

lappa··on FoldingCoin
And the method for getting there is scamming people with a pump and dump coin (that will almost certainly not accomplish what I mentioned).
lappa··on FoldingCoin
Mentioned this in my first post. Basically the currency is a speculative asset that doesn't do anything for DNA folding since the amount you lose from monetary supply increase is could just be donated through bitcoin to DNA folding.
lappa··on FoldingCoin
Being difficult to compute and easy to verify doesn't meet the full criteria for being a secure hashing function.

>As you mentioned, this is a good thing. And as far as the effects on the currency go, this doesn't seem any different from Bitcoin miners moving from CPUs to GPUs to ASICs.

The optimization "problem" is a problem because it can wipe out the currency. The transition to better hardware was gradual, while a software optimization could literally make one persons CPU more efficient than the rest of the world combined.

>Protein folding / structure prediction is NP-complete, so seems unlikely.

While it may be difficult to actually fold the protein, folding the protein such that it breaks one of the assumptions I listed may be trivial.

If we could simply use NP-hard proven problems as hash functions, we would.

lappa··on FoldingCoin
The reason SHA256 was chosen is that it is a hash function. Hash functions are meant to be easy to calculate but difficult or near impossible to reverse and near impossible to optimize.

MD2 was designed by cryptographers and has tons of research regarding it's security. It is now broken.

Protein folding basically has no research regarding it's security as a hash function, because it isn't designed as a hash function.

Protein folding almost certainly has a large optimization problem, an attacker likely could find ways to increase his mining power by orders of magnitude. If the currency became valueable, it is inevitable that someone would make solving this problem constant time.

Now, is making protein folding more a efficient a good thing? Absolutely! But the only way it can be made more efficient is by making this currency useless.

Essentially, the only way this currency can be useful to DNA folding is if the currency becomes useless for securing money.

Edit: It appears that foldingcoin is on top of the bitcoin blockchain so miners aren't even there for consensus. They are simply creating a speculative asset that has an increasing monetary supply that equates to donations to protein folding. The miners are completely unnecessary for security.

lappa··on LSD: The Geek's Wonder Drug? (2006)
Questions aren't assertions, and one of the requirements for straw man is asserting you hold a position.

I'm done with this discussion at this point. I don't think you really have a concrete claim regarding the topic and you are avoiding creating one by derailing the conversation by arguing my question is fallacious.

lappa··on LSD: The Geek's Wonder Drug? (2006)
There is no strawman because I was asking a question about your position, not asserting that you held a certain position.

Please, if your position isn't what I asked, state what it is.

lappa··on LSD: The Geek's Wonder Drug? (2006)
What about that is straw man? I don't think you have a full understanding of the fallacy. The wikipedia definition is

"A straw man is a common type of argument and is an informal fallacy based on the misrepresentation of an opponent's argument."

I haven't misrepresented your argument in any way since I haven't represented your argument in any way. I never claimed you claimed anything. It isn't fallacious to ask someone to clarify an argument.

You didn't explicitly state your argument (or anything of substance), so I asked what you were actually trying to claim.

Lemme know what part of my statement was a strawman.
lappa··on First U.S. Bitcoin Exchange Set to Open
The way Coinbase words it, they may be only insuring 3% of your funds. The online wallet is insured[1], but there may only be 3% online[2] meaning a malicious employee or just a mistake leading to their cold wallet being lost probably isn't protected.

Are you proposing that one should do any drug without skepticism after reading a wired article about it?

Is there a shortage of cruise ships? Perhaps cruise ships require many man hours and not-abundant resources to make. Perhaps software engineers require many man hours to make and intelligent people with a passion for computer science is a scarce resource.

We can say "there is a food shortage" because a certain amount of food is necessary for a society to survive. The same can't be said of software developers.

Also, if you argue a high price means it is scarce, does that mean there is a shortage of hedge fund managers and CEOs?

lappa··on Bad Microsoft
There isn't a STEM shortage, STEMs are just expensive. If you don't have enough STEMs you can steal them from another company by paying more. If your company cannot afford the labor it will die, STEM or not.

lappa··on Riecoin breaks world record for prime sextuplets, twice [pdf]
This scamcoin is uninteresting. Bitcoin has come up with the smallest sha2 hashes (which is also pretty uninteresting). The hope behind Riecoin is that some breakthrough may come about for finding prime sextuplets. The hope for Bitcoin is that no breakthrough will come about for finding small sha256 values.

Basically the purpose for Riecoins PoW is to be broken which doesn't make invest from the perspective of someone using it as a currency.

I would hope Mozilla's ethics prevent them from promoting scams by accepting Dogecoin.
lappa··on Could Ebola vaccine delay be due to an intellectual property spat?
Thanks for the correction. Anyways, at least tripling foreign aid (maybe multiplying it by 10-100) is something that would be controversial.
lappa··on Could Ebola vaccine delay be due to an intellectual property spat?
$48million is a few cents per person.

The US private R&D spending is over $100billion. Spending $3000 per person on what would be mostly foreign aid (7bn vs 300mn people) would be controversial.

lappa··on Some ideas for native Bitcoin apps
Micropayment channels don't offer the flexibility of plain micropayments. Sure I can get $0.0001 from you a certain number of times, but I have to wait until I have a certain amount paid for it to worth it for me to make a transaction.

Micropayments that aren't channels will be possible when fees are lower.

lappa··on Could Ebola vaccine delay be due to an intellectual property spat?
How do you propose having all of humanity fund it? A country could pay for it with their tax dollars, but then it is only a subset of the world having their paycheck decreased in order to help the entirety of humanity.

You need a certain amount of wealth in the country to be able to fund all this research and the US probably could afford it, but since were not going to use patents, taxpayers may become upset that a large portion of their tax dollars are going to foreign aid rather than domestic aid.
