Has anyone been successful in GPU and CPU mining at the same time? If I start 2 instances of eth miner, the CPU one crashes while GPU one works fine. I use coinotron for pool mining.

Can you please explain a bit more? Do you mean there is non yet? and I try to register a domain and do that?
It seems that Etherex promised to do so, But I wonder any regular exchanges also plan to do so or not?!

when i run my cpu to mine, my gpu hash rate is decreased by about ~10%

not worth it to let my cpu mine..anyway it was only an old core2duo intel cpu, win7 64bit..

this might help someone here...when i use only 2gb of ddr2 RAM my GPU's can't mine...at 3gb and 4gb my GPU's can mine.

This is the perfect time to buy some more Ether. I have the feeling that in the next few years its price will be a lot higher than what it is right now and it would be a great opportunity to make some profit. 

Ethereum: Public Consensus Versus Economic Consensus
One of the most intriguing topics touched upon during the recent Ethereum DevCon1 conference is how the challenges in public consensus should be addressed.  Achieving a public consensus sounds easy to accomplish on paper, yet the reality is vastly different.  The Ethereum team seems to have a general idea of what challenges they are facing and how they can be addressed.

Okay.  I watched the Devcon Conference, got excited, and wanted to provide some support to the network.  I transferred some ether to one of the sites developed by one of the speakers invited to speak at Devcon.  The project is called "Gnosis."  It's a prediction market D'APP.  As far as I can tell it is a scam.  I bought shares in one of the markets and won but was not paid, answered, or even acknowledged in the site forum.  If Vitalik is so smart, why would he invite these idiots to speak at the conference?  I only wonder how many other affiliates of Vitalik are also scam artists....just beware of making investments into these projects, even if endorsed by Vitalik!

When will the virtual mining beginning ? Proof of stake proof of work? i tried the wallet and other apps but there is still no option for this.

what are the rules for Proof of work/stake? one week before staking? Staking with every wallet? before i invest in a new coin its interesting to know.

When is MIST official release?

Truly beautiful.
