1  Bitcoin / Pools / Re: [1500 TH] p2pool: Decentralized, DoS-resistant, Hop-Proof pool on: October 05, 2017, 09:12:58 AM
If uncles are added then I think the share interval could be reduced even more to (say) 15 seconds.
For what its worth, average time between blocks on the p2pool share chain was 10 seconds once upon a time.

3  Bitcoin / Development & Technical Discussion / Re: Vanitygen: Vanity bitcoin address generator/miner [v0.22] on: August 03, 2016, 08:10:36 AM
but I have an error with the compile:
Code:
make oclvanitygen
cc -ggdb -O3 -Wall   -c -o oclengine.o oclengine.c
oclengine.c: In function ‘vg_ocl_prefix_check’:
oclengine.c:1553:18: warning: variable ‘tablesize’ set but not used [-Wunused-but-set-variable]
  int orig_delta, tablesize;
                  ^
cc oclvanitygen.o oclengine.o pattern.o util.o -o oclvanitygen -ggdb -O3 -Wall -lpcre -lcrypto -lm -lpthread -lOpenCL

So, I tried to run with this command
 /vanitygen-master# ./oclvanitygen -i 1address
Difficulty: 13419245680
Killed
error? nah man!, compiler diagnostic yes(thats a good thing)
As far as i can tell, oclvanitygen should be working for you. Try adding a -S (safe mode) to your command line is about all I can suggest.

LoyceV,
shit man! looks like you've really sodomized your computer now, uhm
I apologise for that LoyceV . I'm not sure how you can return your system
to how it was now. Again sorry about that. Probably best if I shutup now.
8  Bitcoin / Development & Technical Discussion / Re: Vanitygen: Vanity bitcoin address generator/miner [v0.22] on: February 24, 2016, 02:01:50 AM
Install the OpenCL SDK, how that's done will depend on your graphics card, operating system, where you installed stuff, etc.
I've been trying all kinds of things, but didn't get it to work. Same error. Any chance a reinstall with another (which one?) Linux-distribution can make this easier? I expect GPU-vanity will find 1 more character in the same time as CPU-miner, so it would be very nice to get to work.

LoyceV May I see the output of  '' ls -larths /usr/lib*/libOpenCL.so* ```
Depending on the distro the location of that library will be different.
If you do have the library a simple symbolic link may be all that you need
for vanitygens build machinery to find it.

Wait up can someone please tell me again,

`` bitcoinaddresshere/1 `` is that always submit shares at the target and higher?.
`` bitcoinaddresshere/2 `` is that always submit shares double the target and higher?.

Say the sharechain target is 4 000 000 How does one submit only, shares double
that and higher.

Lets grep the source yeah

12  Bitcoin / Bitcoin Technical Support / Re: script to start bitcoind on: December 30, 2015, 02:10:28 AM
but every now and then I log into the server and find its not running, so i then have to restart it and wait for it to sync from where it stopped.

Crunck
I wonder why bitcoind is doing that, It should just keep running. There may be something in the debug.log that
may explain  why bitcoind is crapping out.

Have a look in this directory https://github.com/bitcoin/bitcoin/tree/master/contrib/init. If your rig is using systemd
there is a unit there, so you can start bitcoind through systemctl. Also a couple other scripts for openrc and sysvinit.
check it out man!

19  Bitcoin / Development & Technical Discussion / Re: Vanitygen: Vanity bitcoin address generator/miner [v0.22] on: October 31, 2015, 09:08:53 PM
I downloaded the most recent version from github and tried to install it on my Mac. When I enter the folder and do a 'make' then I got the following error:

pattern.c:32:10: fatal error: 'pcre.h' file not found

Any suggestions?

I'm thinking the missing development header up there "pcre.h"  is in the package pcre
(on my rig i have pcre-8.37).
The PCRE package contains Perl Compatible Regular Expression libraries.
These are useful for implementing regular expression pattern matching using the same
syntax and semantics as Perl 5.

Now - nfi how to get that on a Mac and why thats not on there to begin with(some portability
reason I'm thinking). Maybe a careful observer in here can comment on that.

Its always a good idea to know explicitly whats needed before installing random packages
and sodomizing your rig, so I can't recommend building from source.

Gluck and sorry for the noise.
