One reason why I dump all my CPU hashes here is I find the coin owner humble and willing to listen to others and seems to have no quarrels with the rest unlike the rest of the coins which seemed to be created out to spite each other.  Some hiccups here and there but seemed to be ironed out with the help of the owner.

Guys, here's a context diff for few % faster implementation of scrypt.c:

You can use this code for other SCRYPT based coins as well. There's quite a bit of opportunity for further optimization, especially on the 64-bit systems, but I just don't have time to do it now. If somebody uses a Visual Studio compilers for Windows, the equivalent of "bswap_32" is "_byteswap_ulong". Have fun.

I don't know why everyone is getting this number of orphans. I only got 45% orphans since 3:05AM GMT.

Daemon at a Public IP address with 19 peers connected currently.
Well it stops at  8 connections for me.
only orphans

also the network latency seems to be an issue, if you are in Europe you're apparently screwed..

I am also in Europe. In the farthest possible place.

Fiat no more.

Tried applying this to commit a8a1f3f8d4f1d3d891c049cd3d3b88e6960d9ca6 version of scrypt.c from ArtForz cpuminer and failed.  I can see what you're doing here, when I'm less sleepy I'll patch this in by hand.

I just checked in code to lock in block 4032 after diff change.
Please grab latest source. Windows client coming soon.

Windows client here: https://github.com/downloads/coblee/litecoin/litecoin-windows-client-40101.zip

Everyone please update.

Unfortunately twobits is asleep and can't help me build a windows daemon. And I only trust him to do that right now.
So for those running on the daemon, you can stay with your current binary. As long as enough people are running the new build, we should be good against an attack. Thanks.

First they ignore you, then they laugh at you, then they keep laughing, then they start choking on their laughter, and then they go and catch their breath. Then they start laughing even more.

does it help to play with the -s factor? I tried lower values but did not notice a difference.

what happened to the idea of a super node for everybody to connect to? my ip is 85.181.140.125:9333 in case anyone would like to connect.  Grin

Compiled and running the 40101 daemon on linux.  Smiley

phelix - setting -s below 3 was very useful before the 4032 block since we were seeing a new block about every 3-4 seconds, so the default 5 second scan time would cause an unnecessary number of stales/orphans, but with the difficulty increase they're not being generated nearly as fast(I think the diffculty went up 400% or so at 4032?)

If you don't want to get wiped out by a 51% attack, you should update. Just stop and the start the new client. You will be down just a few seconds.

Yep, I don't wanna mess you up too bad. That's one of my pool killers, that was a single thread from 1 EC2 jumping across various ports.
that's the spirit

hope it is not you messing with deepbit and slush?

So how often are you going to lock in blocks?  Every retarget will get a bit out of control I'm thinking.

I will lock in the next retarget 6048 and then I will go to sleep and maybe another lock in when I wake up. We'll see. Once the difficulty catches up to the network, it would be harder for us to get attacked.

probably phelix which I added with connect=

also I got 16 orphans and no blocks  Sad
