And we're off! So far no luck with finding blocks  |

-fprofile-generate, run for a while, make clean, re-compile with -fprofile-use. You'll have to add a SIGTERM signal handler that calls exit(0) to gather profiling info. Otherwise the usual litany of -march=native -mtune=native -O3 -msse4.2 already enumerated in the OP.
This is with gcc 4.6, linux64.
Oh, and I'm not using the latest scrypt.c. That one loses about .4 khash/core. The version before that seemed to work best on i7s.

Just use the artforz cpuminer. The git url is somewhere in the tenebrix spew. I caved and re-enabled hyperthreading, playing with flags some more has me at 3 khash/core now on my i7 920s @ 2.66 ghz. Definitely no hexacore phenom, but still usable. 10khash from a Q9300@2.5ghz too! I'll be charging out of the gate with about 40 khash. Looks like I'm not alone here. Tenebrix hash rate just dropped by 50% according to allchains. Hopefully solidcoin will be sucking up people's resources so the first few retargets are smooth-ish. |

How the hell does one go about "disassembling" a binary to get the source code? As far as I know that's impossible.
Then I suggest you google for "disassembler." It is very much possible, especially if you know what compiler was used to generate the code (most likely gcc on linux and of only a few likely versions). The reverse engineered code, like all machine generated code, is absolutely awful. But once you start "cleaning it up" and re-writing it to be more readable you can get to a good enough state to figure out algorithms. Well, ok, maybe not you or me -- but people with the skills and practice to do this demonstrably exist. Even for code run through an obfuscator. This, by the way, is how many games get "cracked." Binaries get analyzed, decompiled and poked at until the security mechanism is well understood. It is then replaced. |

Took me 3 tries to parse that and I'm still not sure I got it right.
When I read the OP I was all like, "Wait, Bruce Wagner... As in the potential scammer Bruce Wagner? That'll go over well once they google him some."

His point is valid though. Another subsidized netcoin mining period is coming up, and this might be the last one (unless bitcoin implodes).

Half a million infected machines is no script kiddie. That's gotta be the granddaddy of all botnets hitting everyone right now. And good job on the submission, yours is the only pool not being DDoSed into being down.

This is very simple. Bitcoinwatch averages blocks over the last 24 hours. If you have everyone producing 0 blocks (this isn't the case) and reporting that the "Other" pie chart is 100% based on past block rates alone.
This is used to happen during difficulty jumps up. For the 24 hours following the jump in difficulty that chart would compute how much hashing power would be required to get the average # of blocks over 24 hours at current difficulty, compare that to reporting hashing power of the pools and assign the rest to "other." Since the average was hashed at a lower difficulty you'd get these giant "Other" slices showing up every retarget.

It's also an instrumental tool to initiate panic.
I was expecting an artificial price spike due to this. I didn't expect it to be so brief or feeble. |

Too early for another powerdump. Also not sure what this means with a DDoS on major pools in progress.
|
|
|
|

Didn't catch the spike, but considering this is happening at the exact same time as DDoS attacks on the top pools -- well, I had a coin or two remaining. Whomever was trying to manipulate the price up now has them, congratulations.

Got my script all set up (basically a while : do wget litecoin.conf && litecoind ; sleep 59 ; done with the tenebrix miner fired up in the other window ) so I hope to be the first. =)
If I can get to the keyboard around the time it's slated to go live I'll bump down the sleeping.

P.S.:
Perhaps a bit of a touchy subject, so feel free to decline answer, but are you currently a resident of the United States?
Just a bit of less-than-scientific statistics gathering on my part...
Yup, been living in various parts of the US forever. |

Bears make money, bulls make money, but pigs never make money. I keep having to re-learn this lesson.  That said, those probability charts are *STILL* eerily accurate for getting the likely direction of the day's trading. |

I cashed out my bitcoins back in July and have withdrawn about 2/3ds of the money, since then I tried to play with the rest - but only managed to reduce it a bit. I wonder how many people did a similar move. How much cash left MtGox? How much is still there? It is very tempting to be back in the game if you have some cash left at MtGox - that's why this bubble deflation goes very slow. If you were an early investor that decided to cash out - how much did you leave on MtGox just in case?
Only MtGox and Dwolla know how much of the original investment is still in circulation. What is certain beyond all doubt is people aren't depositing enough new money to keep pace with even a small portion of current operating costs. Thankfully 80%+ of the mining power is content to mine-and-hold, if they started cashing out enough to pay for power (never mind hardware) it'd be a bloodbath. |

Meh, Tenebrix is doing well given zero blawg and twitter support, zero prelaunch hype, and a "competitor" that has both.
For the love of Cthulhu, what is it about some certain people and pre-mines?
it's like some kind of deep affront to you guys, on a level that seems to go beyond economic reasoning.
The problems with SC2 are not "premine".
The problems are, in no particular order:
weird chicanery happening to the diff, the "peer to pig" architecture itself, absolutely insane obfuscation going on in the "pig node" part of things, blatant electricity theft, and, perhaps, most of all, the amazing invisible source code.
In fact, given the above, SC2 is probably doing better than it should according to "strong efficient market" kind of reasoning.
You say that, but the shit really didn't start hitting the fan until the 13+ million coin premine was disclosed. That's when SC instantly took a 50% haircut on the exchanges while TBX rallied. At the moment your pig at the through exhibition is less offensive than that of a demonstrated liar, but only $2000 dollars is buying into both combined. Congratulations! |

I think what would be for the best would be to start with a not ridiculously low difficulty... So that people wouldn't join just for mining a quick stash during the first days then leave for the next new ccurrency launch and sit on their Litecoin stash expecting it will eventually be worth something when hypothetical late adopters will join and do the promoting job while mining at 1000 times the starting difficulty.
What if you guess the starting difficulty and are wrong? Then you get no early adopters at all and your chain is completely stillborn. Expect 4 megahash, get 30 kilohash. Then six months until the first still vastly overinflated retarget. No, low difficulty and the pyramiding is the only thing that works. Best you can do is tell everyone you can about it so they have the opportunity to compete on an even footing out the door. After it's established what happens is what happens. The OP is doing this right. Currency hopping is the new pool hopping. I find it funny that less than a day now separates "early adopters" from "late adopters" in many people's eyes. |

 The Invisible Hand, flipping off CoinHunter Tenebrix are roughly at partity with SC on btce for both price and volume. Lots of flipping off to go around for both massively premined scamchains. |

S3052 does a great job on technical analysis (I even follow him on twitter to keep up with all the updates) and yes, he considers other things beside the charts, such as the community thoughts here at this thread. I was just saying that every prediction must be taken with a grain of salt.
Regardless of the bitcoin price, volume in currency is an indicator of how much people are trading. Investing $1000 in June means that I can move around 33 BTC. In October it means that I can move 250 BTC. So the BTC volume should be 7 times higher now, but instead it is more or less the same. Either we have the same amount of people investing 7 times less money, or we have 7 times less people. Either way, I don't believe that we can support $30 prices.
May I suggest an alternate theory? The money the "7 people" invested in June has been collected and used to pay for hardware and power by a small % miners. My estimate is 15-20% cash out, the rest are happy looking rich on paper and/or speculating "long term." The remainder of original investment is being traded by a smaller (but not 7x smaller) group. |

Market is very bullish.
I expect 3$ in the next days.
And yes i said bullish. I can't even imagine the price if the market was bearish...
I can. Called $1.25 as a capitulation point at $5, still thinking it's valid at current price/difficulty. And yeah, Wednesday is almost over with no jump up. Nothing much last Sunday either. I don't have high hopes for Thursday, and weekend effect will kick in after that. As a very wise man once said, "drop em or get raped." |
