I have an unusual configuration: on my headless gateway there is bitcoind running and on my desktop standart bitcoin is running (both Linux OpenSuSE, gateway 11.1, desktop 11.3, bitcoin 0.3.12 both). TCP port 8333 forwarded on gateway to the desktop (so gateway client can’t has incoming connections). I don’t know […]

A thought has occurred to me that bitcoins client is released under mit which allows for closed source clients that would give someone an advantage over everyone by modifying the client and not releasing the code. If we changed to GPL this would force anyone who created a modified client […]

DB_PRIVATE enables a few optimizations by making the assumption that only one process will access the db4 database.  Notably, this flag enables db4 to use pthreads-style mutex locking rather than heavy, operating-system-provided flock and shared memory.  Ref: DB_ENV->open documentation. The general motivation is that db4 databases can be safely accessed […]

Quote from: teknohog on September 09, 2010, 19:32:05 Since the function CallCPUID function contains x86 assembler, it breaks the build on other architectures. I’ve changed line 2770 in main.cpp to #if defined(__GNUC__) && defined(CRYPTOPP_X86_ASM_AVAILABLE) to make it compile again, at least on ARM. Added in SVN rev 152 Related posts: […]

I think I know what happened.  Doubleclick on the generated transaction.  It probably has a sub-0.01 transaction fee in it. Someone has been paying a 0.00000010 transaction fee.  I don’t think you can even set that with -paytxfee, I think you’d have to modify the code to do it.  Your […]

If you send your entire balance, then you won’t have enough left to pay any fee. You could send 49.99. […] I think I know what happened.  Doubleclick on the generated transaction.  It probably has a sub-0.01 transaction fee in it. Someone has been paying a 0.00000010 transaction fee.  I […]

If you send your entire balance, then you won’t have enough left to pay any fee. You could send 49.99. I don’t know why that’s happening. There shouldn’t be a fee for any non-combined transaction. What version is the one where this happened?  Release build, or built it yourself?  Which […]

SVN rev 150 has some code to try to auto-detect whether to use 4-way SSE2.  We need this because it’s only faster on certain newer CPUs that have 128-bit SSE2 and not ones with 64-bit SSE2. It uses the CPUID instruction to get the CPU brand, family, model number and […]
