I suspected it, and saw it confirmed when I didn't specify number of threads and read the lines in the log file. Nothing new here but thanks for pointing it out anyway  . |

I just downloaded and built cpuminer-1.0.2. I expected to see some improvements thanks to ckolivas' affinity changes (assuming they have made it into the release), but I'm surprised to find I'm getting the same speed: $ grep CFLAGS_value */config.log
cpuminer-1.0.1/config.log:ac_cv_env_CFLAGS_value='-O3 -Wall -msse2'
cpuminer-1.0.2/config.log:ac_cv_env_CFLAGS_value='-O3 -Wall -msse2'
$ tail */my-log
==> cpuminer-1.0.1/my-log <==

$ _ I tried removing the line that specifies 7 threads but that makes no difference (except for the log messages "Binding thread %d to cpu %d"). Am I omitting some step? The CPU is a "Intel(R) Xeon(R) CPU E5420 @2.50GHz". This is the layout of the CPUs/cores: $ grep -E '^processor|^physical|^core.id|^$' /proc/cpuinfo

I think anything requiring "Updates" (Including Windows and certain GNU/Linux distros, most graphical browsers) is inherently insecure.
I ROTFL'd at this. |

I have a friend with several thousand in his wallet (mined from earlier in the year) and he just leaves his laptop on without encryption and carries it around with him around town. I could have easily transferred the BTCs to my wallet while he was in the washroom.
Do it. Then a day or two later, return him the money . He will learn the lesson. |

Anda mira, me lo acabo de topar en el wiki: Further, PayPal has stipulated that trading Bitcoin is against their AUP, since they consider Bitcoin a currency, and currency trading is not allowed. There have been a handful of reported chargeback cases, and several high-profile account freezes by PayPal for bitcoin dealing businesses (bitcoinmorpheus, and coinpal). It is thus strongly recommended to avoid using PayPal for bitcoin transactions. Que traducido, vendría a ser algo como: Además, PayPal ha establecido que intercambiar Bitcoins incumple ¿la política de uso aceptable? ya que consideran que Bitcoin es una divisa, y el intercambio de divisas no está contemplado. Se han dado varios casos de devoluciones y bloqueos de cuentas "high-profile" por intercambio de bitcoins. Por tanto se recomienda encarecidamente evitar el uso de PayPal para el intercambio de Bitcoins. Esto de high profile se me escapa, no tengo cuenta de PayPal y no sé lo que es. |

Also, you can set your frequency governor to ignore niced processes (at least for ondemand and conservative), keeping the CPU speed down when nothing else needs the higher frequency. Works quite well for me.
Ah, didn't know this. Will look into it, thank you! |

[...] power usage and heat generation. Of course they may be issues in their own right. Is there really a demand for this?
I for one would like to have it. I would have been a long time user of BOINC if it weren't for this. |

Unfortunately, there are still lots of idiot investors, lol
When I was 16 I bought some USD while they were high to wait a bit till they rise even more. Since I lost 30% of investment, I had my lesson. Seems not everyone does.
That's because not everyone has ever lost 30% or more. That's just part of the process. I lost 50% after the dot com bubble. |

Is there a reason why you display only so little data?
I couldn't get ahold of MtGox trade history for more than 24 hours back. Bitcoin Charts has that information. Look at their API. |

They are all of the currencies supported by "th", which is TradeHill.

OP,
Take your loss, educate yourself a bit on charting, currency trading and daytrading and maybe try hunting again later when you are better armed.
How on earth would charting and ccy/daytrading have anything to do with BTC? There are zero reliable "levels" in the BTC market, let alone proper margin accounts, instant execution, depth, etc..it doesn't even make sense to get started to pretend that BTC is in any way a "truly" tradeable market outside of hitting buy and sell on mtgox randomly. Charting is about the behaviour of a heterogeneous group of people. It applies to the BTC market. |

Genial , no hay una forma de sacar los BTC por paypal no ? porque por lo que vi Bitcoinmarket ya no lo soporta mas :S Algo leí hoy mismo acerca de que las compraventas de bitcoins con paypal incumplían alguna de las cláusulas del contrato de paypal, por lo que cerraron el grifo. |

What surprised me is that mt. gox, has a limit where you can only sell $1000 dollars a day. If this is true, this would explain partly why the price rose so high, sellers were not able to unload fast enough.
AFAIK MtGox doesn't let you *withdraw* more than $1000 a day, not sell. If the limit was on selling, the big downwards movement of today would have to be explained somehow. There were single sell operations of 1000 or 2000 bitcoins (I don't remember at what price but it's irrelevant, it would have been a minimum of $13k). |

I like how we first had weeks of posts about how prices > 3$-5$ were not a bubble, then had a nuclear explosion of price(TOTALLY NOT A BUBBLE. +3000% in 8 weeks is normal, to-scale behavior!), then had people "out of the mainstream" hop on board when it was peaking, and then the bubble popped (-50% in 5 days is faster than even the mortgage crisis managed, well done...STILL NOT A BUBBLE..oh wait) and people are now showing the classic "bought the top, sweating blood" state.
When they sell their last BTC for an incredibly painfull loss somewhere between -50% and -90% (go for it OP, just imagine your cash value should we return to 1$-3$ permanently!), then we will have bottomed out.
I absolutely love how even the tiny BTC market 1:1 mirrors the "real world" markets in terms of herd behavior.
It's also incredible how you just cannot escape the whole human nature thing regardless of how little or small a market is..and how well this fits in with explaining why not everyone is a Soros/Buffet etc.
+1 to this. |

The current transaction fee is a pain but that will drop soon.
I haven't found much information about fees. Care to explain in a couple of words why do you think fees will drop? Thank you. |

As a user I would expect that total Mhash/s were the sum of the khash/s of all threads—in your example it would be always around 12 Mhash/s (since each thread works at a consistent pace of nearly 3000 khash/s). That's not the case, so I guess the algorithm is different.

After the big downwards movement of some minutes ago, it went up just when it touched $13 as expected. Midterm bullish is still alive ATM.
