I don't see updates in my graph since yesterday... Something is wrong?

Yeah, the eu server keeps dropping and we are jumping around with coin diffs every couple of seconds.

Pretty sure these issues are unrelated. coinGeek renders the graphs in order of accepted shares from his own database compiled from the allusers table (which is still updating here: http://www.middlecoin.com/allusers.html). The growth of the pool has made it harder for his hardware to keep up and lower hashrate users might not get updated graphs as often. Use the allusers table or one of the monitoring tools in this thread.

Do we even need a fork now that the coin is alive again?
Absolutely.  The coin's never been 'dead' Wink but absolutely can use some fine tuning.  The testnet's adjusting up and down nicely - I'm glad my double-moving average suggestion didn't make the cut.  Grin

What did "make the cut"? The twin moving average seemed like a good idea to me.

difficulty went. up...

Because price is going up...
104  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] Catcoin - Scrypt meow! on: January 22, 2014, 06:15:46 PM
I don't think there is much to worry about. The CAT is out of the bag. It has entered the public consciousness and is linked to DOGE by virtue of the Daily Beast article.

It might be a good idea to postpone any fork until the price and volume stabilizes. Investors are jumpy creatures.

How will price and volume stabilize if minting and delivery do not?

Good question. At this price the profitability is decent even at 60+ difficulty, which is why the last 36 blocks only took 6 hours. The next diff will still be right around 60 again, and as long as the price stays up tx times will stay reasonable.
105  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] Catcoin - Scrypt meow! on: January 21, 2014, 09:56:31 PM
Just tossing an idea out there... does anyone think it's feasible to use coin hoppers as protection against extremely long block times, by lowering the difficulty if a block has not been found for a long time?

For example, the difficulty could drop by 10% if no new blocks are found after 30 minutes, and 10% every 10 minutes after that, resulting in a 35% drop after an hour and 65% drop after 2 hours.

Since a block is normally found every 10 minutes, this would only kick in in cases of bad luck or most of the hash leaving the network; the base difficulty would readjust way down after 36 blocks if the nethash was low enough to kick this off several times.
106  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] Catcoin - Scrypt meow! on: January 18, 2014, 03:14:32 AM
   float refDiff = ( getDifficulty(nHeight - 36 ) +
        getDifficulty( nHeight - 36*2 ) +    
        getDifficulty( nHeight - 36*3 ) +    
        getDifficulty( nHeight - 36*4 ) +    
        getDifficulty( nHeight - 36*5 ) +    
        getDifficulty( nHeight - 36*6 ) +    
        getDifficulty( nHeight - 36*7 ) +    
        getDifficulty( nHeight - 36*8 ) ) / 8;
    float currDiff = getDifficulty( nHeight );
    if( currDiff < refDiff ) nSubsidy *= currDiff / refDiff;
    return nSubsidy + nFees;


Although I understand the reasons to implement some anti-hopper protection, one thing makes me doubt that this solution will work.

Let's say that the difficulty stabilized by some means. Then due to the market situation the coin price drops significantly enough to make cats mining less profitable than other coins. So people would switch to another coins. Eventually the diff goes down and these who stay mine cats will get decreased rewards for quite while. Then, when the correcting factor will be close to 1, the coin could become attractive again, so miners come back and mine at rate 50 coins a block at low, but growing difficulty until it becomes unprofitable again. And the story repeats.

The market reacts much much slower than difficulty change. Those oscillating wont be as obvious.

Up until today I was under the impression I could really pull it off, but since the diff increase today I'm having serious doubts. I'm making around 530Kh/s ...  so its obvious my balance will drop considerably.

No, its not obvious. The higher difficulty means more variability, but the long-term payout should be EXACTLY the same.

My question to you all, specially to those of you who have low hashpower ... However, power bill isn't getting any cheaper, but my hashrate isn't enough anymore.

There is no such thing as "enough" hashpower.  Grin

Do you think ivesting in a couple of 280x/7950 would make it any different right now?

Yes, you will double your earnings by adding one 7950. But again, pool difficulty has no effect on payout. ROI on a 7950 is just a couple months right now.
108  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] Catcoin - Scrypt meow! on: January 17, 2014, 04:38:39 PM
So this probably means that the block reward will not be constantly 50 cat per block ?
Isn't the "new technology" just an average of the last n block interval s / 600 multiplied by the current subsidy ? Or something like that ?

I personally am against the modification of the block reward in any way shape or form. I feel that fundamentally alters the coin, no matter how trivial. In my books, block reward and block time are completely off limits. But hey, this coin belongs to the community, so we will do what the community asks. If that includes changing the block reward, so be it, though my gut feeling says that the large percentage of the community will disagree with that action.

Some of our team is less concerned than I am about such changes, and it has consumed considerable amounts of our resources time wise discussing this very issue. What does the community think? What do you guys want to see in this coin improvements wise? How far are we willing to go? Are there variables that are absolutely off limits?

Agreed.

Personally I'm for maintaining the scrypt bitcoin that this coin was originally marketed on.

Yes.

Personally speaking, an SMA or SWA provides exactly the behavior I think will solve our issues.

I'm sure that this solution will make the coin far more stable if the average accounts for a long enough period. If the goal is long-term stability then the average should look at the last 2 weeks (2016 blocks). I think the current 36 block retarget time is good, although with a moving average the retarget time is less critical.

But, whatever the specs are, the moving average has to be done for CAT to survive longterm. Even a 36-block average with a retarget after every block would be much better than the current specs.

actually all would make sense if H20 start replying on his own topic...

Sleeping on his own sucess... But sucess will not last forever...

Good comunication is the key... not the shity 140 char twitter crap..

LPC

Key to what? Pool growth? Good payouts? Doesn't seem to be a problem with either of those...
110  Alternate cryptocurrencies / Pools (Altcoins) / Re: [ANN] profit switching auto-exchanging pool - middlecoin.com on: January 14, 2014, 01:37:38 AM
Just starting to mine again here.

Do we need to have modded cgminer or standart 3.7.2 works just fine ?

Thanks !

3.7.2 _should_ work fine on middlecoin (the disconnect issues have been resolved serverside), but I use 3.1.1 which never really had the issue in the fist place.
111  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] Catcoin - Scrypt meow! on: January 11, 2014, 07:38:07 PM
Installing new card drivers now. Tense moment as I see whether my PSU can handle two high powered cards.  Undecided

I'm trying to get a new gpu aswell to help with the hash rate, don't know if I should get a 7950, a 280x or a 290, kind of tight on money right now and although it's an investiment with return so I don't know how should I handle this ..

Well, I have it working alongside my GTX 670 now.

The R9 280x provides nice bang for buck, but it runs pretty hot. It's fine though, as they can take the heat, but when it gets to max temp I drop from 700mhash/sec to 635mhash/sec, so realistically to get max performance I'll need to watercool it. It's a bit annoying that I bought the best performing/cheapest R9 280x that I could find, because I'll have to buy a Universal GPU waterblock to cool it now, as it's a non-reference board. Oh well. It'll still be way better than the stock air cooler. A decent 240 radiator should keep it running at 700mhash.  Smiley
 
Nullu have you tried a volt modded bios?  I dropped the core voltage on both of my 280x from 1.2v to 1.1v.  Temps went from 80c down to 70c. it is a surprisingly easy procedure.

Do I have to flash my bios? I'm reluctant to do anything that could cause me to brick my motherboard. Someone suggested I try MSI Afterburner to undervolt.

Do that, i use afterburner to undervolt too.

+1 on Afterburner. I use it to undervolt, and also to control fanspeeds automatically and monitor everything. Best tool I've found so far.
112  Alternate cryptocurrencies / Pools (Altcoins) / Re: [ANN] profit switching auto-exchanging pool - middlecoin.com on: January 09, 2014, 08:57:21 PM
My 290 ran at 96C when mining at 820kH/s (the highest stable I could get, but then again my card seems to be a crappy one. Driver crashes alot when i stop mining and restart etc.)
Now it runs at 65C with watercooling and the same 820kH/s. If i increase intesnity the kH/s decreases. Sux...

I think there is a ton of variance in the power / heat attributes for R9 290 cards.

I have two sapphire 290's. Both hash very stable at 875Kh/s with the exact same settings, but the first runs at 73C at 60% fan while the second goes over 95C even with 75% fan, which forces me to run the fan at 90% and temps are still 88C. So

290 #1:  73C at 60% fan
290 #2:  88C at 90% fan

To make it an apples to apples comparison

290 #1:  62C at 90% fan
290 #2:  88C at 90% fan


You need to crack that open and reapply thermal paste (unless they aren't getting the same amount of airflow, that's critical too).
113  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] Catcoin - Scrypt meow! on: January 09, 2014, 08:49:46 PM
The network hash prediction is quite big right now, for some reason, Coinium is finding blocks WAY quicker than they should. like every 2 minutes, so I believe that's artificially inflating the estimated hash rate, we can only hope that trend stops or the next diff is really going to suck......


http://cat.coinium.org/index.php?page=statistics&action=blocks

http://catcoins.biz/charts/

Coinium got lucky for 3 blocks, but there were a total of 7 blocks found in 15 minutes.

That luck looks like it run out, no blocks for 25 minutes. We are just under 5 hours since retarget, so even if we find 12 more in 30 minutes the diff will only go to 65.

Based on the overall rate for this period (5 blocks/hour = 12 minutes per block), the diff will go down by 20% to 49.6, which would be nice for a change.

Raaahhhrg! What's happening to me?

I'm not at home so I can't check what's going on my puter... Why would I suddenly get all my hashing rejected??

I've seen wireless routers do this, might need to reset your internet connection.

Also, why don't you use Teamviewer or Chrome Remote Desktop to access your miner(s) remotely?
115  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] Catcoin - Scrypt meow! on: January 09, 2014, 06:59:40 PM
The pools are holding strong above 200 MH/s, which is nice to see. SOMEONE is still throwing GH/s levels of hash at CAT though, because we are already half-way to the next retarget. It's not hashcows, multipool, or middlecoin.
116  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] Catcoin - Scrypt meow! on: January 09, 2014, 05:41:52 PM
60minutes of famous
16hours wait it again


We actually hit the last 10 blocks (all dif 59.5) in just over 10 minutes each. The net hash hasn't completely disappeared, so we might get to a retarget in under 10 hours... which would put the diff at a very nice 35.7.
117  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] Catcoin - Scrypt meow! on: January 09, 2014, 04:01:05 PM
Looks like diffi will end in an disaster one more time.
Weather price goes up to a level miner stay mining on current diffi or it will die because
during unprofitably time transactions are too low and investors get rid off the CAT


No it won't actually. We're only getting an extra 500 MH currently from somewhere, down from 4 GH two days ago and 1.5 GH yesterday. Whoever is behind it is holding back. Also next diff estimate is 37.9 which is fucking perfect for us to get back in the game. Let's hope that goes through.

EDIT: looks like new diff might be 59, sure it's not 37, but at least it's not fucking 80 again.

It's 59.5, which isn't terrible if we can keep enough hash around to keep it over 35 the next change.
118  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] Catcoin - Scrypt meow! on: January 09, 2014, 02:37:36 PM
Network is estimated at 390 MHash right now. We shall see if middlecoin shows up to the party (that's who I think is behind those spikes, FYI)
390? more like 150 Mh/s no?

We got 9 blocks in 35 minutes, that's a lot more than 150 MH/s

Middlecoin is bouncing between LTC, DOGE, and something at 12.94 diff (848K). No CAT so far.
119  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] Catcoin - Scrypt meow! on: January 09, 2014, 01:56:10 PM
Get ready for the mass to jump back in in 2 blocks.... :X

One more... Difficulty IS limited to 1/4 on drops, right? I've never actually seen it happen, just wanted to confirm. That means we are going to 19.73.
120  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] Catcoin - Scrypt meow! on: January 09, 2014, 01:07:27 AM
So to resume everything, we should keep working on enhancing the coin with a long term plan, which would advertising plan, pushing the coin to as services as possible, getting media recognition (I tried to writte a wikipedia page but there are no "good" references that I could use) this can be easly done, by tiping webmagazines and techsites and stuff like that, just make sure you writte something that may get their attention and make them writte a whole artical about it. Short term would be fixing the coin parameters to solve the issues we are having and with the Difficulty and the most obvious solution for me is to reduce the maximum change factor from x4 to something more realistic (if it is possble code wise but I think it is)


This is pretty much spot on. I think having the diff adjust after every block is a good idea, but basing the next diff on the last 36 blocks does not provide enough protection against 10+ GH/s pools, which right now can find 36 blocks in a matter of minutes and still leave us with high diffs. Using a full 2016 block average as the basis for the adjustment (or limiting each block's diff change to about 1%) would provide better  long-term stability, which is really what we are looking for.
