Yep, it's still working great over a year later

There were at least 14 I can think of off-hand.

This suggests a broken jansson install - please find your jansson.pc file and PM me a copy (it should be small and plaintext) so I can add a workaround.

Unfortunately, I don't know any way to get useful information from Windows.

Last 3 trolls seem to be missing the fact that the bet deadline was at the end of April 1, not the start of it.

Forgot to push the tags to GitHub, sorry. Should be there now.

It began as a fork of cgminer (a CPU/GPU miner), but not to be confused with the current cgminer, which has become a fork of BFGMiner for trolling reasons.

Do older versions work? Can you run:

Yes, I can honestly deny that.
While I was vaguely aware there were bets going on, I don't and still have no reason to care about their terms or outcome.
If I were doing it to influence a bet, I would have posted it immediately, instead of as an afterthought 20 minutes after I posted them to my BFL-hosted blog.

Whether I did or not, is not my problem. I have every right to post pictures of my device Josh took for me.

To actually answer your question, requires a great deal of defining: what is considered "proof of ownership" and what is the deadline? In the context of the bet (which I had/have nothing to do with), it seems "proof of ownership" was defined as "credible pictures" - so I would say that part is true; it also defines the deadline as the end of the day of April 1st, which my post was certainly before.
But again, this has nothing to do with me. I don't see how accepting my paid-for hardware, or posting pictures of it taken by BFL, makes me in any way a party to the bet or somehow a "scammer". That is complete nonsense.

You say that as if there's any reasonable doubt that BFL is legit, which there never has been.

Core dumps and/or backtraces would be very helpful to debugging any crashes. Did the 2.99.x versions work stable for those experiencing this?

I've not experienced any crashing myself, but it does seem there are conditions where the SC devices have begun to stop hashing (which IMO is much more annoying than a crash), so I definitely need to put a focus on just fixing stuff for 3.0.1.

The getblocktemplate wiki page has a long list of pools, though perhaps it should be merged into the pool comparison page.

All I did was accept a device I paid for a long time ago.
Trying to make me the bad guy here just discredits you even more, and exposes how your bias is the only basis for your argument.

In case you're claiming the risk of "51% attacks" is FUD, let me assure you it isn't.
If there were no risk, then you might as well be using PayPal.

This is obviously another poorly defined bet, yes.
While the first batch is pretty well-defined by BFL, the bet fails to mention whether it needs to begin shipping by July 1, or be completely 100% shipped.
In the latter case, it also fails to define how the answer is to be determined - did BFL agree to disclose when the first batch is 100% shipped? If not, it would seem the former (first batch has begun shipping) must be the case. But this should be explicit.
In the case of "first batch begun shipping", does that include my order (which is obviously pre-first batch) or not? IMO, it shouldn't - but again, this should be explicit.

Now what I'm wondering is... why are people betting on poorly-defined bets?

This is part of the "free market sorting it out":
Having a single entity with blind control over even 25% of the network blocks is a threat that devalues everyone's bitcoins (including their own).
Therefore, it makes economic sense for BTCGuild to try to deter this from occurring.

Too bad they won't allow miners to audit their block data by supporting GBT.

Thank you all for participating. BFGMiner 3.0 has been released with two winners.

First place goes to wizkid057 with "St. Barbara's Faithfully Glorified Mining Initiative Naturally Exceeding Rivals" (400 TBC / 0.67108864 BTC)
Second place goes to mrb with "basically a freaking good miner" (200 TBC / 0.33554432 BTC)

It's not the same bet. One customer is not "customers" - and it wasn't within 10%.

NEW VERSION 3.0.0, APRIL 5 2013

Please note that libcurl 7.29.0 has a socket leak with request failures, which can lead to BFGMiner running out of file descriptors and/or crashing if you have a dead pool! All older and newer versions of libcurl should be fine.

Also note that if you are compiling from git yourself, you must manually run configure after autogen.sh - it is no longer run automatically to be consistent with how every other software package does this.

2.10.6 is also released and promoted to stable. Note it does not support ASICs.

Human readable changelog:

• New device driver for ASIC devices, including both Butterfly Labs' BitForce SC and Avalon.
• Enhanced device driver API, enabling devices to asynchronously handle multiple slave processors. Use --show-processors to view each individually (not yet supported for Avalon).
• You can now use --request-diff <difficulty> to ask for a specific share target from pools that support BIP 23 GBT Basic Pool Extensions.
• Support for submitting found blocks to a local Bitcoin GBT server (bitcoind or Bitcoin-Qt with -server flag): just append #allblocks to the end of your bitcoind's URI.
• Stratum connection resuming support - if you lose an active stratum connection, BFGMiner will attempt to resubmit any lost shares when it reconnects.
• Android target support. You will have to compile it yourself, but it should just work - no patching needed.
• New Python RPC client example from Christian Berendt.
