Does luke-jr have a history as altcoin analyser? His post is very short...
-edit- The hero member obviously means he has contributed some things and the projects in his sig suggest he's a good dev. Just saying I doubt his analysis was thorough.

I've gone thru the code too and I didn't see any obvious bug, but I'm neither a cryptocoder nor I code in C++, so I'd love to get specific pointers to any flaws (and to learn from them!)

Botnet operators don't care about electricity costs.
At current difficulty, it would take a botnet of ridiculous proportions to make much YAC at this point.
Now that we're crossing the threshold where difficulty is high enough to warrant shutting down Xeon-based servers, even at very low power prices ($0.065/kWh over here), I believe the cat is probably out of the bag regarding whether GPU mining of Yacoin is occurring. Just examine the current difficulty and block rates, and work out what the hash rate is even after power prices start swamping even high-power-efficiency Xeon servers. Sure, there's going to be some small amount of people who have free power (as in, "free to them"), but I doubt it accounts for anywhere close to the apparent network hash rate at the present time.
After GPU mining becomes economic, I'd like to call for everyone that experimented with scrypt+chacha/kekkac modifications to cgminer to post their modified source. I doubt it'll be useful for any more alt-coin copypasta launches in the future. Just like what happened when Amazon become uneconomic to mine with and everyone started posting details in this thread about their Amazon-hosted server farms, it would be even far more interesting (at least to me) to see what everyone's approaches to implementing scrypt+chacha/kekkac in OpenCL was. As has been pointed out, it's not a trivial copy'n'paste. But it's also not catastrophically difficult for anyone with decent amounts of OpenCL experience.
Anyone willing to post GPU hash rates for Yacoin at least, prior to it becoming uneconomic? That should at least dispell the myth that N=32 somehow made CPU's faster than GPU's for mining YAC. N=64 in another couple days isn't going to change the GPU vs. CPU performance ratio all that much, and as Taco pointed out earlier, GPU's are still going to have the edge at N>1024.

Any guide on compiling minerd (scrypt-jane) for Ubuntu 64 bit and CPU Athlon64 x2 ? I installed Ubuntu 12.04 few hours ago so surely missing a lot of dependencies there.
Crude tip, but it tends to work: whenever it says whatever.h is missing, do "apt-file search whatever.h", then look for a package named libwhatever-dev

Haven't you dumped all your YAC? I think you did so how about moving to some other altcoin now and leaving those still interested in YAC alone?

Already did, yep. Just warning people. I've moved on since.
A post and my reply from a different thread is below. Probably it's more relevant in this thread than over there:
I think what's going to happen is that when GPU mining of Yacoin no longer appears economical, multiple people are going to post their modified cgminer source. Exactly like what happened when Amazon EC2 become uneconomical, we all started sharing lots of details about our Amazon-hosted Yacoin mining server farms and Vycid even posted a detailed howto showing one of several methods (perhaps not the most efficient or expedient method) to do it.
Expect the same type of information sharing to occur when GPU mining of Yacoin becomes uneconomical, since it's likely everyone thinks there isn't going to be additional scrypt+chacha/kekkac based alt-coins released so there won't be any advantage in keeping the modified cgminer source secret. At that point everyone will be after bragging rights, saying, "Hey, I was one of the first to get cgminer going on Yacoin just X hours after the coin launched, here's my modified source!"
At that point it's going to be interesting to examine the different various approaches each person took to porting scrypt+chacha/kekkac to cgminer. I'll find it most interesting to see and compare everyone's approaches indeed.
Such a niave little boy...Both FTC and CNC are doing poorly, but this one will do better, because it can only be mined by CPU, which costs considerably more them GPU mining. Why would anyone want to make more profit, mining a real, already tested coin, like LTC. That's just silly

Incrementing N will lead to immediate hashing speed decrease. Difficulty will reflect these speed changes (i.e. difficulty will decrease after N++) with lags. As soon as block reward depends on difficulty the reward will increase also and more miners will be motivated to join after N++. It's not easy to predict now but we can be sure that some waves will happen on each N++ event.
when will this event be?

Nice tweet by coinmovers about YaCoin.
"Yacoin is one of the few coins with character and a purpose for existing. Mining is preferable to buying at this time. It is CPU only."

Congratulations to all the community for bringing this nice project all the way to this point.
But remember, the objective is to allow people to use YAC as a fast and secure cryptocurrency for trading goods and services. Let's keep working on that.

All should focus efforts on getting YaCoin used to buy and sell goods and services. Has anyone setup of bounty for this?
