Calma lá rapaz.
Esse miner USB aí, corrijam-me os especialistas na mineração, é só para mineração PoW em SHA256, método de criptografia usado no Bitcoin.
No Litecoin temos um outro cenário, onde ele está com o PoW em Scrypt, outro método de criptografia usado no Litecoin, que assim sendo, tu precisa de mineradores específicos para Scrypt.

A BF eu não sei, mas Satoshi já havia previsto o pruning do database, o que significa que as transações gastas não permaneceriam eternamente no blockchain.
O cliente referencia (bitcoin-qt) implementou parcialmente o pruning na versão 0.8, o problema é que se a rede toda começar a usar um blockchain reduzido então não será mais possível ter um histórico confiável de todas as transações, teriamos apenas as transações e address com saldo disponível, mas somente alguns poucos nodes teriam o histórico completo.

É uma faca de dois gumes, ou temos um blockchain gigante, ou reduzimos a confiabilidade delegando o histórico a alguns poucos super-nodes.

A escalabilidade é um desafio imenso.

Bem, é inveitável que o blockchain atinja um tamanho enorme a ponto de ficar inviável um computador comum de suportar, não só o tamanho do arquivo em si, mas também a lentidão que vai ser ler todo o blockchain antes de abrir o QT. Isso num cenário atual, claro que a tecnologia pode mudar e o preço dela também, mas não dá pra contar com a sorte. Uma adoção em massa do Bitcoin mais alguns anos de uso e teríamos um enorme problema, talvez não só no blockchain, mas no tamanho dos blocos também.

Finished playing Castlevania: Lords of Shadow. The history starts good, the middle sucks, the final is OK.
The gameplay is not too much evolutive, you'll find yourself ding the same cmobo a lot of times.
And god, the "Forgotten One" is a ridiculous boss. It forces you to do aerial combos(what you simply don't have), secondary weapons doesn't work against him and there's no health and magic recharge before him after the first battle. They simply tried to make him a difficult boss, but it became an annoying boss, since you have 30 ground combos and only 2 aerial combos.
I hope that the second game that will come soon is better, but doesn't lose the essence of a Castlevania game.

Pois é, bem mais ou menos, foi dito quase nada, até parece que essas 48h foram 4h.

Só falta as grandes mídias como Forbes fazerem bom uso do senso e fazer um artigo como esse.

I watched some of it. Pretty fun. I play Dota 2 sometimes but I'm not too much into it.

I would try playing it online(I played only the training), but my internet connection seens more like a sine function, sometimes my ping is X, other times it gets to X+300.

Vamos ver se a opção de pagamento vai funcionar bem aqui no Brasil.
Pena que já comprei um notebook recentemente, quem sabe compre algum acessório de lá só pra testar.

Oh my god, did anyone here that the dota 2 international 2014 will be streamed on espn. Jesus that is massive.

Ofc, the prize pool is the biggest ever saw on e-sports. Valve is swimming in money from the "Compendium" thing.

Recently started playing Castlevania: Lords of Shadow.

It has a mix of God of War + Shadow of Colossus + Prince of Persia,  the only thing that I'm not very happy with the game is the autoplace cameras. This shit ALWAYS give the worst position to see the where are your enemies.

Anyway, I already found someone that will buy it to me, just waiting to get the code now.

I can buy a gift code after the login, but since in the local currency it costs a lot and I got a few bitcents, I prefer to someone out there to buy to me.

I know that I already bought that, but this time is for a friend of mine.
No accounts, you will buy a minecraft gift code direct from their site.

Name your price.

Any thoughts on the third place game?

Thinking Brazil has lost all heart and will lose this game too

Netherlands said that this game is unecessary.
They are not going to play really well, so Brazil haves a chance to win this, even better with Thiago Silva's return to take a better control on the defense.
696  Economy / Services / Re: WE PAY FOR SIGNATURE EVEN MORE. UP TO 0.0016 BTCs PER POST. W on: July 11, 2014, 02:53:06 PM
I just hope that "soon" means less than a week.
This guy is already 4 days late.

Is UpDown truly a BTC Foundation Member?

Escrow or upfront payment?
Newbie never seen guy making a campaign, too much risk on it to take.

Well, since I already lost a day and I'm not realy that active on the forum I'll pass and wait the monthly payout.
I would probably be between 12~18 posts on 17 July.

OK so, since bitcoininformation joined I feel a bit better about joining it, since he rates all those ads.
But a few informations before I even try to join it:
You are going to pay monthly, but requires a minimum 25 posts per week?
