Oh, man, you really fucked up.  Here are the packages which depend on upstart, and which would have been removed accordingly when you removed it.


If I were in this situation, I would probably reinstall.  The alternative I would try first would be

1) Boot from a live CD

2) Mount the hard drive

3) chroot into the hard drive

4) apt-get install upstart and the above packages.

But it's not guaranteed to work without a lot more that 3 BTC of effort (or even 20 BTC, at least the way I figure my own time.)

  Like I said, where's the demand?  When everyone and his dog wants bitcoins, the price will rise.  It rose at the start of the Summer in anticipation of it taking off as an alternative medium of exchange.  And that may well happen, but so far it has not, and its adoption will face severe resistance from established powers.  I want it to succeed, I am fascinated by it, but so far I have not seen a convincing use case to drive widespread demand for it and overcome the inevitable establishment resistance.

  What is your contribution?

Suggest you wait a couple of months and reassess then before investing serious money in this project, unless you're just doing it for fun.  A new generation of GPUs is coming out, as well as commercial FPGAs.  The difficulty/price ratio is likely to get harder.

The python-json repository has moved.  The OP should update those instructions.  This is the new way to download that code:

What do you mean, the fundamentals appear sound?  The fundamentals appear awful, to me.  Where's the demand for bitcoin, at this point?

Can you point me at the second tutorial?  I am only aware of the one in the OP.

Hmm, I read carelessly, thought step 13 was the download of pyopencl, since it was the first place it appears in the sequence.  It appears that those instructions are incomplete.   Try downloading it with the command

That won't work, because the output of the find command indicates that the download did not succeed.  Did you complete step 13. from the OP?

Either you're in the wrong directory, or the download didn't succeed.  Send the output of the following command (may take a while to run, as it is crawling your entire filesystem.)


If you followed the instructions in the OP, you might also try   If that runs w/o errors, try Cntrl-a Cntrl-Space a few times until you cycle through.  One of the windows you see in this process will contain the wget pyopencl command.  If the download has finished, run the command , note the directory path it reports,  and follow the instructions from there.

  Tell us the output of

Oh, sounds similar what I was suggesting, yeah.

While the OP's baseless slander of Bitcoinica is definitely beyond the pale, the general concern he raises is valid.  Services like Bitcoinica, MtGox, etc. are completely unregulated and unaudited, which would make any serious financial commitment to them fairly irresponsible.  I think a service like Bitcoinca could allay a lot of fears and get a lot more business (my business, perhaps, anyway) if it submitted to voluntary regular audits from an independent audit service following the Sarbanes-Oxley requirements.  (I know Bitcoinica etc. are not subject to Sarbanes-Oxley by law, I just think it might good for their reputation.)

Multiple hashing rounds are a common way to slow down hashing searches.  The only question to my mind is why bitcoin only used two rounds, since the whole point is to make mining a computationally expensive enterprise.

Just some suggestions on structure.  In order to reach a broad audience, you'll want to give a very high-level overview of how bitcoin looks to an unsophisticated end-user, then cover the politics, economics and ideology, then the applications, and last the crypto and other protocol details for reference.  Putting the theory first will drive most potential readers away.

 Definitely worth the trouble to take a look.  It is like stumbling into the marketplace in a Hollywood libertarian dystopia.  Oh, and don't forget to take a look at the forum there.

Hitler actually came before the internets.  Little known fact.

Bwahahah.

I can log in.

Remember, it's just speculation.  I have zero evidence that this is going on.  I'm putting it out there as much to see whether it stands up to scrutiny as anything else.
