Could anyone share an up-to-date addnode list?

Dedicated high-speed one in the signature.

Could anyone share an up-to-date addnode list?

Two nodes I'm running:

addnode=85.168.249.60
addnode=188.165.216.59

I have two others but they are already maxed out, 300/300 connections. The second one has a 1000 limit.

Raising the limit of incoming connections to 1000 may crash your node eventually. If you really want to do that, you need to increase the maximum number of open file descriptors first. This command will try to increase that to 2048 on Linux:

Code:

ulimit -n 2048

Now you can run "ulimit -n" to check that the new setting is taking effect. If it's not working, there may be a limit configured in /etc/security/limits.conf.

I did some more research into this and using "ulimit -n 2048" won't fix things. The problem is that glibc's select() implementation only support 1024 file descriptors. That's hard-coded into the system header files. There are some #undef and #define hacks around that but they don't seem to be safe. It's probably best to stay below 1000 connections. I'm running a node with maxconnections=750.

At the current rate of 0.5 USD / XPM, I don't think that any (legitimate) VPS farm could ROI without speculating on a huge rise in USD/BTC price. Only "free CPU power" diverted from exploited machines could see profits from XPM today.

Anyway, we'll see if it leads either to a decrease in difficulty, or if the exchange rate goes back to 0.6+ in the following days. There is the current upward trend of USD/BTC, but currently besides hobbyists and a couple of fortunate hardware holders, I don't think this rate + diff is sustainable in the long run.

tl;dr: XPM is cool and hopefully here to stay, but not quite profitable to "mine" currently IMHO

you are right, let's hope the big dumping is done now...

Does primecoin still produce a block per minute?  Seems like less, though maybe that just because the computing power soo slanted towards those with huge server farms, botnets and 100s of VPS droplets

It's usually more than a block a minute because it takes the difficulty algorithm time to catch up to the faster miners people are writing. You can see that here:

http://192.241.170.170/

One block a minute is 1440 blocks a day, it's usually higher than that.

A lot of people are paying for a month at a time up front so there is no incentive for them to stop until their month runs out or a more profitable cpu coin comes along. I get the impression there is a lot of bot netting going on now as well, mostly using ypool as is makes it easier to get the coins. They of course are happy to sell at any price.

Maybe our users are not aware of what products/services are available through Coin Payments, looks like pr0d1gy decided to delist XPM and PPC from Coin Payments for now.

https://bitcointalk.org/index.php?topic=285619.0

I feel having support of the first multi-currency payment processor is important, not just for our sake, but also for a healthy competitive currency market in general. So please let Coin Payments know that our community is really active and interested in using their service, so hopefully they can reconsider this unfortunate decision to desupport two of the most innovative currencies both in the top ten market cap ranking.

You can leave your feedback in the above thread or PM pr0d1gy.

Avast blocks the site. Sigh.

[Lauda]

As always, and no response regarding the matter..

[EskimoBob]

Sadly, this turned in to the "mining is pointless for small guys" really fast. This sucks.

It depends on what the point is. If you want to make a quick buck, I'm sure there are better ways than volunteering in a math experiment.

Now there is a vote on which currency to add back.

As of 9/1 we will be removing the follow coins:
PPC - WDC - XMP

Why?
Due to the lack of transactions

In my opinion, the useful thing to do is not to write them and just ask that they leave it there, but rather (or also) to improve on what is the primary cause.

It seems almost all discussions about primecoin are about mining, and the technical aspects of it not even the mathematical implications behind. A lot of "I get X blocks with a xeon XYZ", "I did not get any block since 2 days, is it working?", "I finally got a block, I can confirm there is a lot of variance", "how do you compile on ubuntu XYZ?", over and over again.

I am convinced that it would be beneficial for the coin that there would be somehow a community of users behind, not only a community of miners. Some more services need to be set up, primecoin-specific (even better) or not, but the total lack of widening in discussions is a bit worrying for the future of the coin. At least as price is concerned, if these aspects do not improve, I'm not seeing the coin going anywhere.

This is normal, the coin is in its accumulation stage.  That will drecrease as the difficulty increases

Is there anywhere I can buy something with primecoins? Chicken and egg situation I think.

Didn't know you could buy games with XPM!
Thinking of Devil May Cry, I loved the anime
