1  Alternate cryptocurrencies / Mining (Altcoins) / OSX Mac/Hackintosh ethereum miner CUDA build on: February 06, 2018, 11:02:55 PM
Just went through the process of building ethminer with Cuda for OSX - it appear simple but devil in the details, its very frustrating... I spent way too much time on it, but finally it works! No more idle time for Nvidia on mac!

Hope it will save somebody a lot of time and frustration who is up for same challenge. It's a Genoil/chfast one:

For some evil reason lol they provide Mac build but it crashes in OpenCL and not compiled for Cuda at all. You need build 0.12. It works for opencl only, but speed is a disaster - ~2mh on 1070. Newer builds not working on OSX at all.

So what I did - 10.13 High sierra, latest Nvidia web drivers, latest Cuda 387.128, lots of pain and suffering and build is here:

To run in Cuda Mode for example on ethermine pool:

./ethminer --farm-recheck 200 -U -S -FS -O 0xYOURETHADDRESS

you can try OpenCL as well (-G instead of -U, but its horribly slow)

1070 getting 26.33 Mh/s, not that bad.

One more thing - for some reason 3gb cards work on Linux version, but on Mac - nope, dont even try, you'll get memory allocation error.

2  Alternate cryptocurrencies / Altcoin Discussion / DAICO - what are your thoughts about it? on: January 30, 2018, 05:56:33 PM
I cant find relevant discussion by searching, so sorry if it's duplicate...

Vitalik recently posted his thoughts on "improving" ICO model by combining it with some DAO features:

I have really mixed feelings about this one. It may work well if amount of participants in said DAICO is very large, otherwise future of the project can be and will be heavily manipulated. It's common practice in conventional investment models when people "buying in" into board seats, bribe/make alliance with other board members and do whatever they want with company otherwise.

Would love to hear your thoughts about it. Thank you.
3  Bitcoin / Project Development / Looking for cybersecurity experts to collaborate on a project and beta testers on: January 28, 2018, 04:25:57 PM
If you have time to spare, verifiable experience and references, please PM me.

Experience with mitigation of DDoS attacks and other cyber threats is a big plus. Diversity of experiences with various environments and systems would be the best.

Please also drop me a line if you would be interested in becoming a beta tester of cyber threat protection system.

Thank you!

The London gold fix, the benchmark used by miners, jewelers and central banks to value the metal, may have been manipulated for a decade by the banks setting it, researchers say.

I suppose it is time for gold and banks to be declared illegal!

Some HSBC customers have been prevented from withdrawing large amounts of cash because they could not provide evidence of why they wanted it, the BBC has learnt.

That is why we need bitcoin

4000£ a large withdrawal lol, it isn't even enough to buy a proper oled tv  Cheesy
10  Other / Off-topic / Why it is difficult for bitcoin to become mainstream on: December 27, 2013, 05:43:11 PM
You underestimate the idiocy of people

Once in class we wrote a paper with the school laptops. The laptop had a intel inside sticker what was curved on one of the corners so it hit my arm arm all the time annoingly. I was taking ut off and the teacher said:"Stop! It is there for a reason. The computer might not work without it. Im pretty sure the principal wont like it if we take it off without asking." Really wanted to take it off. But didnt want detention (yeah she threatened me with detention if i took it off.)

And you expect these people to use bitcoin?  No way they can understand it.

The good thing? We don't need them. Its their fault if they don't want to learn how to use it.

12  Economy / Speculation / To me this looks like an inverse bubble on: July 05, 2013, 07:24:14 PM
In a bubble people race to buy because price is increasing faster and faster and thus they want to get in and profit.

Now? The same, people race to sell so they can buy later at a cheaper price, everyone of course hoping to buy at the lowest price.

To me this is a bubble too, eventually it will pop and people will stop selling. Then people will start to buy again as fast as possible before price increase too much. Ye well, except of course the one who apply the "buy high sell low"tactic  Cheesy

Or maybe i'm wrong and price will drop to 0  Smiley

14  Economy / Speculation / To who whined about early adopters that bought cheap coins: now coins are cheap on: April 13, 2013, 10:02:03 AM
So in the past weeks i was reading about people that were like "omg early adopters bought cheap coins, while we can buy them only at 250, it is unfair"

Yeah well, now they are at 100, and some days ago even lower. If what you say is not epic trolling, then NOW is the time to buy.  Smiley Or you will come back when bitcoin will be at 500 crying "too high!" ?

16  Economy / Service Discussion / To wallet user: do you have a backup of the wallet? on: April 05, 2013, 02:45:58 PM
I'm curious to know how many people have a backup of their wallet and how many do not and trust it to not disappear or else they lose everything...
17  Bitcoin / Bitcoin Discussion / My thoughts about the blocksize thing on: February 21, 2013, 04:33:45 PM
Since everyone and his dog is openin thread about that, i'll hop on the bandwagon too  Cheesy

But my doubt is another one, right now, with the 1MB limit, the blockchain at max can grow of like 55GB per year. If we have the necessity to increase the block size, this mean that every block is already 1MB and that in a year the blockchain will be like 60GB.
If we double the blocksize, it will be 110GB per year. In 4 years it will be like 440GB. With the current limit, 220GB, still a lot

I am not against increasing the blocksize, if we have lot of transactions, it must be done. Also more transactions per block means more fees for the miners, after all it is not expensive to make a 1mb or a 2mb block, but a 2mb block will have more transactions. Yes, the 1mb block would have less transactions but with higher fees but i think the 2mb block in total would have more fees.

And as i said, having a blockchain of 220 or 440gb is not a big difference, it is a huge chain anyway. The problem is that it is huge, even with the current limit. A bit too huge.
18  Bitcoin / Bitcoin Discussion / "change" addresses and paper-wallet on: February 19, 2013, 05:21:01 PM
I was thinking how the "change addresses" thing will cause problems eventually. Why? Well because 99% or more of bitcoin users do not know about that, they think that if they have BTC in the address A and they spend some of them, then they will just have less btc in address A. They make a paperwallet, backup, or whatelse and meanwhile use it.
Then when one day they will use the paperwallet they will notice that the btc are no more in that address but in a new one due to how the "change" works.
Or not?
19  Economy / Service Discussion / Wurm Online and CoinLab, making ingame money via mining on: November 03, 2012, 04:55:16 PM
I remember some months ago reading about CoinLab and about their idea of involving games and gamers to use their gpu to make ingame money. But i never read that they really did this!

It is from June. They did it  Cheesy

Yes, probably mining bitcoins for ourself and then selling them for $/€ or directly ingame money is much better, but still, it's not a bad idea.

Too bad in a month it will die, ASICs are coming  Cheesy
20  Bitcoin / Mining speculation / The BFL driver page on: September 16, 2012, 08:07:27 PM
I don't know where to open this so i put this here

In the BFL website driver page we can find

Computational research
Medical imaging
Packet integrity verification
Generic fingerprinting engine

and in the homepage
Butterfly Labs manufactures a line of high speed encryption processors for use in research, telecommunication and security applications.

Yeah well, nice but...erh... problem: BFL so far only make bitcoin mining hardware. As far as i know nothing else. Medical imaging? Computational research? Lol? Why putting links that just bring you back to the driver page for these things?
