Yes, any miner can do this.
Nothing stops miners from ignoring all TXes and just issuing empty blocks. But if many miners would do that, people will set their TX fees to higher values and there will be someone to collect those fees :)
Also users may migrate from pools that do bad things.

Even empty blocks are useful to make blockchain longer and more secure.

1. 350-380 MH/s per dual-chip Spartan6 board at ~20W.
2. $560
3. Not really a good deal because you'll lose lots of time for manufacturing the PCB and collecting all the components.
Also you should remember that soldering BGA chips is not a task for newbies.

Deepbit offers optional permanent bitcoin address lock.
E-mail address can't be changed too.

No, but it's much easier to visit than any european country (well, except for january because I'm busy now).

Is there a way to save "Don't use smileys" setting instead of opening Additional Options and checking it each time ?

What's the price for upgrading from "Donator" to "VIP" - 40 BTC or 50 BTC ? :)

It's clearly mentioned on the main page - proportional fee is 3%.

Tails не видел ни разу. Ну OpenSSL-то там должен же быть, наверное ? В нём есть приличные алгоритмы.

Да, это удобно, только 6%+ комиссия мне не нравится

Для бэкапов во всякие почты я бы использовал внешнее шифрование.
TrueCrypt как надёжное или OpenSSL как везде доступное.

"e-mail notification on idle" parameter is incorrect in this table.
We have e-mail notifications when no getwork requests are received from user's miner for some time.

"Formation date" is 24.02.2011

Hmm, that "effective fee" is a nice idea, thanks for the hint !
Now I can advertise my fees as twice lower :)

Finally a good place for meetup :)

Does it means that you are getting 320 MH/s per chip ?

I checked the Google spreadsheet and everything was fine there.

Ok, but what's the point of making knowingly inaccurate one ?
I mean, why throw out a top3 pool and top GPU miner from the list ?

So they would allow entry if he didn't said anything about bitcoins, but just not having cash ?
Yes, you can say "USA customs don't account bitcoins as convertible currency", but you CAN'T say that wasn't allowed to enter because he mentioned bitcoins.

Oh, you were talking about power, it makes sense then.
Actually the more important is the low-voltage supply. ATX PSU can only provide most of it's power as 12 V and FPGAs need something around 1.2V, so additional regulators are required. But using one 1.2 regulator for many boards will require expensive high-current connectors, so multiple chips per board would be effective solution (of course if you won't need to replace bad/faulty chips :)

If you need just one then it's fine, but for larger quantities onboard ethernet controller would be cheaper.

I don't think anyone is going to offer PCI or PCIe solutions at least in 2012 because
1) It will make the board much more complicated.
2) It will require more complex drivers.
3) It will require a computer with enough expansion slots. Mostly dedicated miners are going to use FPGA/ASIC hardware, not your average gamers/overclockers, so it's not like "just add a board", they will need many of them with as small overhead expenses as possible. Also building big farms with only a few boards per case is not space-efficient.

Why place a board inside if one can just connect an arbitrary number of external boards ?
But actually I don't like USB and can expect Ethernet-connectible solutions, may be even with autonomous mode, not requiring a computer at all.

Is this "voting" really serious ?

• "Pools" category is missing BTCguild, one of top3 mining pools.
• "Miner" category is missing poclbm (or GUIminer) - almost the first GPU miner and almost the most popular one
• "Nefario being denied entry to the US after mentioning Bitcoins" - where did you get that info ? The article says that he was not allowed to enter USA because he had not enough cash/funds to live there or failed to prove it.
