cpu-miner.c:43: error: ‘SCHED_IDLE’ undeclared (first use in this function)

Your OS needs to update /usr/include/sched.h to include this definition.

If you add
   #include <linux/sched.h>

does it fix the problem for you?

1842  Bitcoin / Development & Technical Discussion / Re: Who pays transaction fees on: June 14, 2011, 02:27:21 AM

RE microtransactions:  this is a FAQ.  It is even in satoshi's original paper and crypto postings.  Bitcoin was never intended to be a useful microtransaction network.  Bitcoin is not optimal for microtransactions, and probably never will be.

RE fees:  the rapid increase in value caught everyone by surprise.  Months ago, we were dealing with "penny flooding" on the network.  Now, 0.01 BTC is a non-trivial amount.

Right now we are releasing new versions of the software as fast as possible, trying to fight the biggest fires ("triage") impacting users on the network.  We know fees need work, and there are already pull requests trying to deal with this:  https://github.com/bitcoin/bitcoin/pull/289

Longer term, we want the community to participate in a discussion about how to best balance (a) rapidly changing bitcoin value with (b) protecting the network.

Right now most transactions do not require a fee, but the default client requires a fee in a few situations:

1. Transactions smaller than 0.01 BTC
2. Transactions whose byte size larger than the 27k free transaction area (very rare)

So, to answer the question "why not make it easy to ignore fees?" is really unspending is very difficult.  If it's just a checkbox for users, a lot of users will uncheck it, their transactions will not get relayed or confirmed, and their coins are simply lost in limbo: never confirming, and no way[1] to recover.

Losing coins is a horrible user experience, far worse than having to pay 0.0005 BTC.

But we are open to all suggestions about transaction fees.  You just have to understand the "unspend" problem in its entirety, and the support nightmare that goes along with it.

     Jeff




[1] Technically, this is not really true.  You can "unspend" by restoring a wallet backup or some other esoteric means, but this is not something within the reach of your average user.

1844  Bitcoin / Development & Technical Discussion / Re: [PULL] Wallet Private Key Encryption on: June 14, 2011, 12:02:07 AM

Hoping to make this a priority for the next release.

Review requested!  https://github.com/bitcoin/bitcoin/pull/232

1845  Bitcoin / Bitcoin Discussion / [ANN] Bitcoin version 0.3.23 released on: June 13, 2011, 11:44:21 PM
Win32, Linux, MacOSX and source releases for bitcoin v0.3.23 have been uploaded to
https://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.3.23/

This is another quick bugfix release, trying to deal with the influx of new bitcoin users.

Priority for next version:  wallet encryption

Main items of note:

  • P2P connect-to-node logic changed to reduce timeout a bit.  The network saw a huge influx of new users, who do not permit incoming connections.  This change is a short-term hack, to more quickly hunt for useful P2P connections.  Better "leaf node" logic is in the works, but this should let us limp along until then.  One may use -upnp to properly forward ports, and help the network.
  • Transaction fee reduced to 0.0005 for new transactions (see note below)
  • Client will relay transactions with fees as low as 0.0001 BTC (see note below)

NOTE:  There has been some fee confusion recently.  Free transactions are supported and relayed as they always have been, according to special anti-spam rules.  See https://en.bitcoin.it/wiki/Transaction_fees for details.

Full git changelog:

Dean Lee (1):
      Updated Chinese Simp translation

Doug Huff (3):
      Fix rfc1918 and rfc3927 compliance for ignoring non-internet-routable host
      Add common temp files to .gitignore.
      Demystify a few magic numbers.

Han Lin Yap (2):
      Added Swedish translation
      Remove unused variable

Jeff Garzik (4):
      Bump version to 0.3.23.
      Reduce minimum TX fee for new transactions, to 0.0005.
      Lower minimum relay TX fee to 0.0001 (from 0.0005) BTC.
      Add minimal release process docs.

Matt Corallo (1):
      Fix CPU Usage bug when using -nolisten and have no connections.

Nils Schneider (1):
      create keypool in LoadWallet()

Pieter Wuille (3):
      Update transactions already in the wallet when rescanning.
      Fix for small change outputs
      Faster timeout when connecting

There were no changes between -rc1 and -final.
1846  Bitcoin / Mining / Re: pushpool - open source pool software on: June 13, 2011, 11:21:38 PM
for example, multiple pushpools and multiple bitcoind?  multiple pushpools and one bitcoind?  other? 

Multiple pushpoold's and multiple bitcoind's.  The only question is about database scaling...

      If this token and others are legitimate, please use m4_pattern_allow.

Any suggestion?

Standard advice -- your autotools installation is old or broken.  Use release tarball.

1848  Bitcoin / Bitcoin Discussion / Re: Jacob Appelbaum: "Bitcoin Prediction: Major bugs in the near future ..." on: June 13, 2011, 05:02:42 PM
Do you agree that transactions are not safe if not included in the block chain?

*facepalm*

This is stated in satoshi's original paper, and should be patently obvious to anyone.  Block chain confirmations equal transaction security.

Quote from: kjj
Section 5, Conclusion.  You don't understand any of the important decisions that went into the design of bitcoin.  Either that or you are a very special kind of troll.

Pretty much.  The vast majority of this stuff is covered in satoshi's original paper, the wiki or FAQs -- all of which are easily accessible.

1849  Bitcoin / Bitcoin Discussion / Re: My summary of recent events on: June 13, 2011, 07:21:40 AM
There is also -upnp option...

Cool. What's stopping it from being default?

It's open for discussion...  some people want it default.  Others are concerned about bitcoin opening a port on a firewall by default, a potential security issue, they claim.

Input is welcome, particularly examples of popular, in-the-field software using UPNP by default.

Does switching from a newer version to a previous version mess up the wallet.dat file?

Probably not, we've taken steps to make sure that works.  But if you jump back too far in time, that could create a problem.

Quote
Is it possible that the previous version might have not handled full precision transactions properly?

Define previous version.  All recent versions handle full precision correctly, though the UI might not display it or other cosmetic details like that.

1852  Bitcoin / Development & Technical Discussion / Re: [ANN] Bitcoin v0.3.23 release candidate available on: June 13, 2011, 04:09:46 AM
There will be a lot of fee-related UI changes in the next version.  Matt C already has a 'better fee UI' pull request at github.

This version is just to triage the P2P network, until we get to that awesome, big next version with wallet encryption and other useful things.

The point of v0.3.23 is to release it fast, fast, fast...

So people: test, test, test!  Smiley

1853  Bitcoin / Bitcoin Discussion / Re: [WTF] MtGox moving ~432k BTC (4 to 12 million $) to a single address ! on: June 13, 2011, 03:43:58 AM
If no one invests in making their marketplace or site bitcoin capable because all they see is insane paranoid scheziophrenics who believe the government wiretapped their bathroom to steal their bitcoins then how is it ever going to get popular support? I want bitcoin to succeed, it's an excellent idea but currently the community seems to be really trying to destroy it (announcing they're going to use it for tax evasion, purchasing drugs, government conspiracies and such like).

We're working on a forum reboot, switching the current mess for a more business-professional one at weusecoins.

As the "official" bitcoin forum, this is just an embarrassment.

1854  Bitcoin / Development & Technical Discussion / Re: [ANN] Bitcoin v0.3.23 release candidate available on: June 13, 2011, 12:31:05 AM
Why does it still say "Fee 0.01 recommended"? (under settings->options)

Hum... good question...

1855  Bitcoin / Bitcoin Discussion / Re: My summary of recent events on: June 13, 2011, 12:18:21 AM
The last few weeks have been interesting ... and I'm sure every week will bring more interesting news.

This is my own subjective summary of recent events, and a bit more.

RE speeding up client:  -dnsseed does the same thing as manually grabbing fallback nodes.

1856  Bitcoin / Bitcoin Discussion / Re: mtgox might just kill Bitcoins chances of success on: June 13, 2011, 12:16:11 AM

Bitcoin is tiny, and will be for a while yet.

That means, necessarily, that one bored VC or trader can create a major move in the market.

Volatility is a given when it's young.

1857  Bitcoin / Pools / Re: SOLVED [Bitcoins.lc] Issue with invalid shares (10 BTC bounty) on: June 12, 2011, 06:45:50 PM

Oh.  This is an old and well known problem.  Nothing to do with pushpool at all.

luke-jr worked around it in bitcoind with http://luke.dashjr.org/programs/bitcoin/w/bitcoind/luke-jr.git/shortlog/refs/heads/getwork_dedupe but there are other options for varying the coinbase as well.

1858  Bitcoin / Development & Technical Discussion / Re: [ANN] Bitcoin v0.3.23 release candidate available on: June 12, 2011, 06:41:04 PM
But for example in 3.22 when trying to send a very low priority tx, you were forced to pay a fee. Do you now have the option to not send with a fee even though it will likely take a long time to be confirmed?

No, you have to hack the client in order to send spam.

In the future, people are considering a checkbox to avoid the recommended fee.

With over 50% of the hashing power, you decide what is the rules.

*facepalm*  Wrong.  If major miners deviate from what the rest of the network accepts, then they are simply self-selecting themselves away from their client population.

If 80% of the hash power suddenly decides to start minting 100 BTC per block, that does not imply that clients will follow their lead.

The entire community, including holders of bitcoin, must decide on major network changes.
