New feature... Timezone support.  ;-)  Set your timezone in your account settings.

Cool, thanks for that, my head only seems to work in NZST or UTC (GMT).  I am getting old

No worries, glad I could assist.  One side note... you may see some changes immediately, and others will take a few minutes to fall out of the cache.

Anywhere you find it not working after ~15 minutes, please let me know and I'll see what I can do.

Cheers.

This came in via PM today:  (hope the author doesn't mind my posting this... doesn't seem sensitive at all)

Hey, burnside!

I've been mining at your pool and I wanted to make two suggestions.

Maybe you could add a record of how many shares and ltc earned on each block on the block stats page.

Second, a stat showing how many blocks you've found total. Maybe put a top block finders list on the pool stats page even? Hey that's 3 suggestions!

If I think of some more I'll send them your way!

Thanks for the pool btw, I like it. I don't know why but I seem to have problems with some of the other ones but yours works well for me.

Shares and ltc earned on the block page is now working.  I noticed in the process of doing this that the estimate that shows up in the header/title bar is calculated using proportional per round equations, not pplns 500,000.  I'm going to have to fix that sooner or later.  Simplecoin is definitely buggy out of the box.   

Blocks found total on the pool stats page is also now working. 

Great suggestions, thanks!

What mods did you make to pushpoold?

Is there a git repo I could pull them from? I run a private pool and would love to lower the stales

I'm hoping you just missed this. The irony of using an open source pool daemon, open source web front end for an open source crypto currency but keeping your modifications private would be too thick.

haha, yes, that would be quite ironic!

And I apologize, the patch is actually to litecoind, I believe it's available elsewhere here on the forum, but here's a patchfile for the latest version from coblee:

Ironic perhaps, but totally allowable.

I know it is a side topic, but the GPL does not require you to release modifications that you make, even if you use it commercially.  As long as if you sell the modified code you include the source you are good, and even then, the party that you sell it to is not obliged to release it.

Yup, definitely allowable and legal, however, to not share is not so much in the spirit of community and collaboration.

Still, I won't likely be giving up the source to the site quite so easily. Simplecoin v5 is riddled with issues and add to that the bitcoin=>litecoin conversion... it's definitely a lot of work getting it functional.  I have a ton of respect for pooler and the ozcoin guys, they have some really nice polished pools.

Added time to retarget (time until next difficulty change) to the stats page.

You may have noticed some strangeness in the block payouts the last couple days.

Two days ago I noticed the pool wallet had lost 50 LTC, and discovered another simplecoin bug where it was paying for orphans.  (not a good thing for a PPLNS zero fee pool!)  I tried to fix it and ended up instead breaking things worse.  It started paying out all blocks found instantly.    So it was doing that most of the day yesterday, not a huge deal.

Tried to fix it last night though, and broke it in the opposite direction.  I did an SQL query with txid = '' that should have been txid IS NULL.  So for the last 8 hours or so it wasn't paying out at all.   

This morning I fixed that.  The first cron run after I fixed it paid out all the blocks properly and things are good so far.    I think we should be stable from here on out.

Cheers.

How does one change their pin?

How does one change their pin?

Can't right now... lemme look into it.  Might not be all that hard to add to simplecoin.

Ok, you should be able to change your pin now from the account details page, just below the password change section.

Cheers.

I wondered what was going on, saw a bunch of stuff all go completed at once. Was that part of what was going on?

Yeah, that was the part where it was paying all blocks found instantly.  heh.  That wasn't a huge issue because we didn't get any orphans during that time. 

Simplecoin has a few fundamental logic flaws in how it was connecting up generate and immature blocks with the database of winning shares.  To assign a transaction id to a winning share block it was looping through the transaction log oldest to newest and connecting up to the newest winning share from the database.  It also didn't have any checking to see if a winning share already had a transaction id before overwriting it.  What this meant was that if there was more than one generate block in the time between cron runs, it would assign the wrong transaction ids to the wrong winning share blocks.  Since it tracks the confirms by transaction id, this was resulting in orphan blocks getting paid out occasionally, confirm counts being wrong, etc.

I fixed it by reversing the iteration on the transaction log to loop newest to oldest, and inserted checking for if a winning share block already had a transaction id assigned.  Cleaned it up nicely. 

This particular bug doesn't surprise me much.  It's only an issue when you're solving blocks rapidly.  Not really something that you have to deal with in BTC very often.

Hope that all makes sense!

Cheers.

That is good but I should have been more clear. I do not know my pin so cannot withdraw. PMing you now.

Ahhh!  haha.  yes, for those issues just PM me.  We'll figure something out.

Glad to see the pool chugging along nicely. Keep up the good work and let's get some blocks!

I tried this pool for the first time with both Reaper and cgminer, neither could connect to server ltc.kattare.com

Anyone else run into this recently? Is the server up? Or do I just have no idea what I'm doing.

The exact same cgminer works fine with my 5870s on deepbit for BTC, so not sure what is going on.

Things seem to be chugging along smoothly.  Did you make the necessary config changes to use scrypt instead of sha256?

I have example reaper configs posted on the getting started page.  Just make sure you're on the 13 beta.

Cheers.

[burnside]

On what 13 beta?

From my getting started page: "Track down and install reaper version 13b4 or higher.  (Wiki http://wiki.solidcoin.info/wiki/Reaper)"

Soon as I make the transition to cgminer myself, I'll add it to the getting started page. 

Cheers.
