N = 36*10+1;
It's "signals" arrays length (don't like any dynamical memory allocation anywhere).
Those code representing 36 blocks sliding window and i simply want to see period as long as 10 windows.
N can be any value (not 36 dividible may cause some problems in this code, but it's only quick overwiev)
You should mention about astatism of diff recalc.
It's relative, so algorithm don't know what difficulty need to set for hashrate, it even don't know exactly hashrate.
Algorithm operates on how need to multiply current difficulty to get target block time with assumption(maybe aprove through probability theory),
that block time reverse proportional to hashrate with same difficulty and most important - that blocktime proportional to
difficulty with same hashrate. And all of coefficients of proportions is unknown and more, random (with distribution law
depending on the hash distribution law). And i use very symplified model of most probable average time (think it's "Expected value" in english terms).
Take it from LTC calculator as i remember.
If you take in account astatism, and tests show that blocktime stabilise on 10 mins after hashrate change and hold both ways, i'm calm.
And yes, catcoin never been anonimous, but i'm about logo design. My "serious cat" not a cake too.
I'm explain. Actual logo on my opinion has expected standart advertisment design. If you think about
food or traveling company logo it's what first come to mind - light offce mainstream style. And "old" anime-style
(not fan of anime, only like "ghost in the shell" for it's cyberpunk setting and not very simple plot) kitten was what you
never expect from currency, somehow original(in this place) and rememberable. It was cute and not serious,
it was attracting, something which "CATcoin" name can be accosiated. Posche - you imagine porsche 911 design. Bmw - you remember
double front grill and sign. Microsoft - you remember windows logo. Bitcoin - BTC. It's about associations.
If those gray kitten has no name and story behind it it's the best logo. Still offer gray kitten on mars surface.

I discovered if I close my wallet, and start it up again, the problem returns. The wallet stalls endlessly and will not sync. I can keep up using the delete and rebuild method, but there is a bug in the wallet system that would be nice to be fixed. Developers please take note. Thanks.

I think you're fine, it's just an hour behind because no block has been found since, which is a problem, but not with the wallet. If you want to make sure, check http://catchain.info/chain/Catcoin and see if your wallet has the same block. It shows 2 hours behind for me too, which is true, we're not even close to 10 minute blocks.

I'm worry about those waves on diff vs block number graph. I think there is a problem.

Is actual algorithm use average diff as good as blocktime?
If it use average without construction such as red_line_in_code_above
it will have diff spikes and hollows.
Correct it immediately if it's so. We will be anough with sliding window,
no need to invent bicycles with 12% and other excesses to diff recalc
algorithm and imagine yourself gods of cryptoworld.
And where is old logo? It was much better than actual.
Actual one have lack of one thing (it can be called idea byt in is not fully correct).
I don't know how to say about it, try to ask artists. Those thing, which make you
recognise product in mass. Like doge on dogecoin sign, like BTC on bitcoin logo,
Like double front grille in BMW.

My wallet has been like this for daysss. Any idea what is wrong? I copied the conf. file to roaming, so now it is in both places, right? Thanks for the help.
Try deleting you blockchain and redownloading it. You can do this by deleting most all the dat files in %appdata%\CatCoin. DO NOT DELETE WALLET.DAT MAKE A BACKUP OF IT WHILE YOU'RE IN THE FOLDER AND KEEP IT SOMEWHERE SAFE.
Your advise worked. Thank-you very much. Do just as he says, including .dats in the folders, but not the wallet.dat, and it fixes the stall forever problem. It does a fresh rebuild, but does not take that long.

I think coinium has F*&KED again as after they fixed the first fork problem, I have been mining with 1M/hash and have earned 0.2 in a WHOLE DAY
We haven't had no blocks. Without blocks there can be no chain fork.
Oh right I thought we were finding them, but oh ok cheers.

glad it works!Don't suppose you could also fix the wallet links on the front page when you get a chance? Seems they're still linking to the old wallets.
We might be seeing somewhat of an influx of new miners and traders soon now that the coin is somewhat functional again and we're getting a little attention now, so I think it'd be wise to ensure that at the very least the wallet links are pointing in the right direction.
Updated. It's pretty straightforward -- it's hosted on GitHub Pages at https://github.com/catcoins/catcoins.github.io

GRAVITY WELL MAKES THAT MUCH HARDER.
The community in the long run is the life of the coin. Every coin has proved this principle. The more black magic there is in the code, the less the community is able to adapt and participate. This effectively kills the coin or makes it the province of established owners of the old system. SEE New York City HEARINGS. They don't understand it. They are afraid of it. They can't even compromise because it is all technowizardry to them. And yeah they're also trying to own it.
