1  Bitcoin / Pools / Re: mining.BitcoinAffiliatenetwork.com - we're giving away 1 Antminer S3 every day! on: August 19, 2014, 06:26:45 AM
I registered a new account at https://mining.bitcoinaffiliatenetwork.com/.  I got the email, followed the link, it said that it was successful and to log in.  Trying to log in doesn't work.  I get a very brief message that a token expired and try again.  Many tries later I figured I wasn't typing fast enough and used paste.  Still no joy.  So I sent an email.  Except that failed also.

Running a mining pool is complicated.  I have to wonder about a pool who's web page will not even work.

The mathematical probability of hitting 2 blocks in the 99th cumitive distribution factor is astronomical, roughly the same as hitting 2 at <1, not quite the same as the 99th is infinite since 100% can never be achieved.

I'm not really sure what you mean, but by definition the lower tail 0.99 CDF occurs when an event is expected to occur one time in 100.

If that's for one block, it will require total work of 4.60517 times the network difficulty. If it's for two blocks, it will require total work of 6.638352 times the network difficulty.

In the first case we would expect this to happen once in one hundred blocks; in the second case once in two hundred blocks.

That's not even close to infinite.

Actually it is multiplicative not additive.  Thus it is one in 10,000.  Which if you extrapilate out at the same difficulty means it should happen about once in 25 months.  I.E. hardly a once in the life of the universe event.

No, it's not. By definition, a CDF of 0.99 is a one in a hundred occurrence, whether the event involves one block or 10 blocks or a thousand blocks. 

We are not discussing one event.  We are discussing 2 events and now a third.  Yes a CDF of 0.99 is one in a hundred.  However the chance of 2 CDF 0.99 events occurring back to back is one in Ten Thousand.  The site does not calculate the CDF of multiple blocks.

About 30% of users currently have problems connecting to the mining server. I'm looking into it.

And we're back. Data center got it fixed. Apologies to the ones who got disconnected there.

This seems to be happening a lot lately.  Is it going to be an ongoing problem?

Some change made about 3 days ago has broken the update script in firefox.  The page now loads and shows the loading box but never loads so the orderbook and transactions never show up.  This is probably the same problem several others have noted.

While I would agree the batch 1 Jup's were worthwhile to the original buyer if they spent USD on them, 60 day estimated payback covers almost 6 difficulty changes.  Its hard enough estimating two changes out.  When HashFast delivers you will see that 60-day ROI turn into infinity.

Just currious.  How many PetaHashes do you expect and when do you figure they will finally ship?

write error could mean the beaglebone storage is full or corrupted.

Now the problem.  I shut the full speed unit down for a few minutes to change locations and when I restarted it cgminer fails to start.  The bone boots and I can tty into it.  I can try to manually start cgminer and I get a "cgminer failed to start: Write Error".

I'm not able to find the string 'Write Error' (without caps as well) in cgminer source code.
Is it the exact error msg you get ?

If so I guess your issue is located somewhere in the OS.
Anything useful in the log file ?

*Note: journalctl is the replacement for a "less /var/log/syslog"
http://www.freedesktop.org/software/systemd/man/journalctl.html

I have not gotten a result from journalctl.  Probably because it is not in the path and I don't know where to find it.

I haven't messed with a Unix system for 30 years so I am a little rusty.  :-)  I would be more at home in JCL.  I guess in the morning I will have to go find a good Linux book.

Trouble shooting wise.

Make sure all the power cables are correctly attached.
Do a hard reset on the device:

The cables are correctly attached (powering down wouldn't have changed them in any case)

I did a hard reset then ran through all the various firmwares before I posted.

Lastly, If you can isolate the bad board, then you can just return that bad board for an RMA and the miner can continue mining, you don't have to lose the entire miner and 480Gh/s just for one bad board.

I have isolated the bad board.  Being able to RMA a single board changes things somewhat.  I will probably do that after the next difficulty increase.

I am not sure this is the right place for this but this seems to be a catch all thread so here goes.

I have 2 late October Jupiters.  One I was able to get to 550 with all cores running under 98.1 beta.  The other has 2 cores on one board that will not work until 73C or 74C and as soon as they start the whole board shuts down (I assume thermal shutdown) so it only works at around 480.

I was living with that (not economically feasible to give up 480 hashes for 2 weeks to rma the thing just to maybe get another 60 or so).

Now the problem.  I shut the full speed unit down for a few minutes to change locations and when I restarted it cgminer fails to start.  The bone boots and I can tty into it.  I can try to manually start cgminer and I get a "cgminer failed to start: Write Error".

I tried changing firmware.  Cgminer will run on 98 but not on anything after and on 98 I have all die 0s dead.

Anyone have any clues?

12  Other / Beginners & Help / KnCJupiter API hooks to control fan speed on: November 09, 2013, 01:46:54 AM
I am looking for someone familiar with the beaglebone and ASIC module API with reference to controlling fan speed through software.  The fans on my units are all 4 pin and on 4 pin connectors so I have some hope that they can be controlled with a script running on the beaglebone.

If anyone has a reference for the API and can help me out I would appreciate it.
