I also had been mining, but when looking at this, I think to continue no longer.
Once you get home, to stop the mining program.

Someone has a little too much CPU power on their hands...

Headline tomorrow: Steem goes viral in China

Been mostly supercomputing and rabbit since I started mining a couple of weeks ago.

Makes you wonder if that is some kind of bot net.

Did we just discover Craig Wright's supercomputer?

Wow I just checked my time to produce a block.  It went from 1100-2200 to 18000-36000 minutes.  So min 12.5 weeks to find a block now.

Or someone has developed a GPU miner and keeping it for themselves

Have been mining on a decent Xeon rig at about 41k/h/s for ~ 2 weeks. Haven't got close to a block. Agree devs should cycle through the lineup somehow to avoid centralization. The last thing we want is another Bitcoin-esque mining cartel... Just pick randomly from everyone that meets the minimum hash/latency and try to ensure as much as possible unique miners are selected via account names, ip addresses, etc.

Btw, there is no point for @supercomputing to add any more resources into Steem mining when he already dominates the queue because it is not possible to mine more than 1 block every 63 seconds anyway.

It is somebody he found a vulnerability on POW mining and exploited it.
In fact @arhag has discovered it and has already informed the devs.
There is already a fix ready on github that will take effect on the next hardfork  https://github.com/steemit/steem/issues/256

You can see more details on channel #mining at https://steemit.chat/

At least supercomputing is not hiding this, so prob not immediate risk.  Don't the witnesses provide the price feeds?

good job @alphabeta.  I will notify those I know about it.  This post will probably get some upvotes.  Like i said--good job ;)

Of course the devs care about this. Apparently this guy has discovered a "loophole" in the mining algorithm that enables him to outmine everyone else. @abit or @arhag can explain the technicals if they want, but anyway they already see a fix so the loophole will be closed.

What's cool about this is that it means some very smart minds are looking at the algorithm, which will only help it grow stronger. 

Hats off to mr. supercomputing :)

It's not viable for supercomputing to continue mining with rewards that can only be cashed out over 104 weeks. Most likely some rented AWS server.

And now Miner-witness queue  list is 123 long. But two weeks ago list was max 105 long. I very sad with mining. My cpu power go nowhere :\
