Just something to file away in the back of your mind with poolpicker is that the earnings they show are before fees etc.  Also you should keep in mind that if the pool pays out in something like BTC and you still have to exchange it for other coin then your going to have yet more fees involved.  I know a lot of folks are after the BTC so it isn't a big deal, but for those who are acquiring other coins this adds up pretty fast.  

When I tested zpool I didn't feel my earnings were quite where I expected them to be, and I still had to exchange coin so the cost added up.  I felt like I was getting decent results with multipool.us, BUT again you end up acquiring lots of different coins that you may not need or desire so your back to sending off to exchanges and going through that.  Again overhead of time and cost.  

I am currently using Prohashing.com and they seem to be working well.  I was turned off by the higher fees, but I feel that is offset by the fact I can have them pay me in any coin I want, and the dashboard features and support have been decent so far.  I am always on the lookout for better opportunities of course, but after discovering that poolpicker is showing gross earnings, and not net and the fact my own experience didn't seem to net what I was expecting I am a lot more cautious with poolpickers recommendations now.  

I would recommend everyone give each of the pools a try over a couple of days and see what you get.  You might have a different experience than I did.  For now I am hanging around at Prohashing with my A2 and still trying to buy a Titan.  

*Profitability calculator*
Our profitability calculator aims to be a global database of mining hardware with records of mining performance as well as past and expected future earnings. This database is open to public and anybody can submit the performance of their hardware: https://www.nicehash.com/index.jsp?p=calc

*New miners page*
We understand that monitoring the performance and profitability of your mining rigs is a vital and essential feature. Therefore we improved the miners page. The new mines page aggregates data from all algorithms and both locations into single, comprehensive page. No more drop-downs and confusions with locations and algorithms!

*GPU Farm rental*
The core feature of NiceHash is to offer on-demand hashing power rental service. However due to the complex nature of hashing rental system some algorithms are not supported. To cover the full range of our customers needs, NiceHash also provides the ability to rent physical GPU miners through our certified third-party GPU farm providers: https://www.nicehash.com/index.jsp?p=gpufarmrental

Okay, let this be all for this anniversary . We would like to thank you all very much for being our customers. We'll work hard to furthermore improve NiceHash, release new features and make it one of the best cryptocurency mining places.

Yep, there are errors, sometimes every new release brings new friends ones  

You'll have to fix them one by one. It's worth it because in the process of fixing you'll learn a lot of new stuff

Maybe one day I'll make PR on github.

I suggest you also have xcode, macports/homebrew?

btw, my first builds I did on OS X 10.10 too, now I've upgraded to 10.11, and basically nothing changed.

So we have two new block explorers:

http://europecoin.blockexplorers.net/
http://gsmcoin.blockexplorers.net/

Please announce them on the specific threads.

anybody knows what is the problem I have that more than 1 time today and I did not get any stake after 67000
Regards;

Updating the staking algorithm to PoSP.

With PoSP (PoS participation) only wallets that are open and staking actually earn any stakes, so if you never open your wallet you never earn any stake interest. Or increase to 2.5X for people staking 24/7.
