Bump...  The source code was released, so I don't see anything wrong with giving the reward out now.

Is the source compilable on nVidia and AMD GPUs? Who released it?

Pretty sure there using this http://wiki.solidcoin.info/wiki/Reaper

I'm assuming this was released by mrtlt (sp?). I will find him on IRC and give him the rewards.

Otherwise, the leap in logic is as ridiculous as suggesting you may as well molest toddlers if, after having slept with your 16 year old girlfriend at age 18, you've already crossed the line anyway.

I pulled the latest source from Bitcoin and also checked in a bunch of fixes to address the "Address Spam DoS" bug. The fix I put in is temporary. I'm working on a real fix, but it's going to take some time. It's really late now, so I'm going to get some sleep.

Unfortunately, I have not had the time to build any binaries. So you will need to grab it from source.

They just sent me an email that SIGNIFICANTLY MORE than 25 people have ordered one at $15,000 each, and they will honor all these [legally probably non-binding] commitments. So, you can give it a shot and try to order one on their order website. If it still says $15,000, chances are, you'll be in.

Just think, it only takes 500 of these (or 200 rig boxes) to match the current network hashrate of 10thash/s. With all the BFL rigboxes and LC C200s coming online in a few months, difficulty is about to explode. My previous calculation of 1 year breakeven at this lower price will be way off if difficulty explodes.

Coblee. If you're working on something can you at least let us know? I'm starting to think that litecoin has been abandoned.

I've been working on putting p2pool in the client, but I'm no longer sure if there's enough demand for that. Let me open this up. What do people think needs to be improved with Litecoin?

Why would value plummet, if the practical usefulness of the txn medium for users remains unaffected? Will the silk road users refuse to buy drugs using coins controlled by a 51%? Should speculators anticipate this mass protest and sell? Is there an economic logic behind this, or is it just the conventional wisdom?

Because this miner can choose to not process your transactions. So if you get paid in bitcoins, you may not be able to spend them! The decentralized appeal of bitcoin will be destroyed if one entity can control what/when transactions can go into blocks. They are currently already not including any transactions into their blocks.

The guys asked for it. He's a thief and comes here to brag about it and asks for advice to further steal from his company. And he's stupid enough to use a username that gives away his real name. Seriously?

Not a big deal if you are using the system to make send payments or speculate. However, if you are currently mining, it is a big deal.  It is a matter of time before this guy/group or someone like this guy/group chooses to exclude blocks found by other miners.  All they need is 51%. The days of profitable, independent mining are numbered.

I hope these people are also ASIC manufacturers because that would be really funny.

1) Sell a bunch of expensive mining hardware to lone miners to recoup development costs.
2) Maintain a dominant residual share of this hardware.
3) Use the dominant share to shut out all the suckers who purchased mining equipment from you.
4) You have all newly mined coins and revenue from equipment sales. Your customers have worthless hardware.


If they invested a lot of money into getting such a big hashrate, it would be extremely stupid of them to perform this kind of 51% attack. Sure they will get all the mined coins, but bitcoin prices will plummet when this kind of attack becomes successful. Because then that means one entity has total control of the coin. If they indeed manage to get 51% of the network, it would be far more profitable for them to mine normally and stay hidden and mine the majority of the coins.

When you sign up using the form, you don't put down the deposit right away. When they get back to you with the escrow detail, then they will ask you to put down the deposit. I assume at that point, they will let you know whether or not you are one of the first 25 and you can decide then if you actually want to go through with the order.

When I do these kind of calculations, I try not to take price into consideration by comparing this miner with buying bitcoins. With $30k now, I can buy 6000 bitcoins today at the $5/btc price right now. According to http://www.alloscomp.com/bitcoin/calculator.php at current difficulty (1496978.59503), 20 GHash/s earns you ฿408.51. Let's also assume difficulty stays constant. So from July to December, you will earn ฿2043 (5 * ฿408.51), then mining reward halves and you only make ฿204.25 a month. So it will take an additional 19+ months (19 * ฿204.25) to make back the remaining ฿3957. So at least 24 months to breakeven.

If I had ฿6000 bitcoins today, would I use that to buy this miner? ROI is 24 months at the optimistic low end (where difficulty stays constant, 0% pool fees, and free electricity). If difficulty increases 1% a month, ROI increases to 30 months. At 2%, 39 months. At 3%, 64 months. At 4%, you would never make back your initial investment. The answer is an easy no. Warranty is only 90 days, yet you need at least 2 years to make back the money. If the hardware breaks down after a year, you are SOL.

Here's an updated calculation based on the updated price. The unit is guaranteed to deliver by 7/31/12 and the cost is $15,000 or ฿3000. Assuming difficulty is 1,496,979 and doesn't change and mining rewards halves on 12/10/12. And lastly assume no power cost.
MonthBitcoins Mined
08/12฿410
09/12฿410
10/12฿410
11/12฿410
12/12฿273
01/13฿205
02/13฿205
03/13฿205
04/13฿205
05/13฿205
06/13฿205
So you will make back your ฿3000 by around June of next year. Breakeven is ~10.5 months assuming no power costs and difficulty stays constant.

i was going to buy the camera myself when it was first introduced.
How many MP is it?

It's only 1080x1080. So 1 megapixel if you think of it in terms of a normal camera.
714  Bitcoin / Hardware / Re: Taking Lytro pictures of my FPGAs on: March 10, 2012, 07:22:52 PM
Holy crap, so awesome. I heard about these on the radio, but really wanted to actually see a picture. So cool that the first one I saw was of an X6500!

Thanks!

Can I post a link to this on fpgamining.com, or even better, embed it?

Yes, of course. Click on the Lytro logo and you'll see a way to embed it.

Ok, thanks! It'll be a part of our new "Gallery." Actually, embedding it would require some shoe-horning into the site template, so I think I'll just post a fixed-focus shot of it, then link to lytro.com for the real thing.

Thanks again! I'll post a link when the site goes live. Cheesy

If you want, I can take some more shots of it. Let me know what kind of shots you want.

Please send your donations there. I will send the private key to the the person that delivers the source code.

sir, with great pleasure I watched the pictures
do you accept and appreciate donations for great posts?

Sure. Thanks.
