Errrm... So today I decided to investigate the performance issues of my block explorer.
You know how some pages take literally ages to load, eg. the one for the richest address?

Although the poor VPS has only 590MB available RAM (with another 1GB as swap), the bottleneck is actually the CPU...

So I sifted through the bitcoin-abe source code for hours, just to stumble upon this: http://gregsramblings.com/2011/02/07/amazon-ec2-micro-instance-cpu-steal/

TL;DR: FUCK YOU AMAZON!

I have yet to decide whether I'll switch to a bigger instance or ditch amazon altogether. Do you have any good VPS provider recommendations? I tried chunkhost for a bit, but my VPS got restarted several times during a one month period, which is unacceptable. The EC2 instance has not had a single unwanted reboot since I started it, quite impressive.

Sux. Still, as you mentioned it is pretty reliable and it will be hard to find something better in that price range.  I've heard a lot of good things about this place lately but never used them so have no clue if good or not.   http://www.dreamhost.com/servers/vps/

Try lowendbox, or get a low-end dedicated. Don't want to give specific recommendations, but delimitervps offers (when it's not sold out) Intel Atom servers for just $5/month (quarterly) and freaking dual Xeons (Core 2's I think) for $20/month, which I have one of. Search lowendbox or webhostingtalk for the coupons. Offset it with a bit of CPU mining (don't think you're going to get $20 a month, but it's something.)

Others that I can recommend (mostly unmanaged):
ramhost.us (if they're not sold out)
ramnode
buyvm.net (has great storage servers)

PLEASE don't mine on VPSes (except on-demand instances such as amazon or digitalocean). Recipe to get you kicked from your webhost, and violates every TOS imaginable. With a dedicated, it's yours, so no one cares.

Thanks for the list! Any of them accepting BTC?

I've rewritten the code to actually allow consecutive PoS blocks, but only give non-zero trust to the first one. Also, if my math is correct, YAC is supposed to have 144 PoS blocks/day (10 minute interval), not 720.

I didn't know PoS had a 10 minute target.  I thought the 1 minute block target was for both PoW and PoS (1440 / 2 (half PoS, half PoW) = 720 blocks per day).  I get up to 10 PoS blocks per day - does this mean I'm actually am getting about 7% of the PoS blocks for that day?

If I'm understanding your last post correctly - does this mean (the change to the block trust) that we shouldn't see a difference in the way transactions are being minted currently?  Basically seemly other then the wallet update?

Yeah, nothing changes for the user. Only the trust value for block is calculated differently to try to reduce orphaning.
I'll try to do some graphs on PoS block interval or something soon.

The only web hosting that I know that accepts BTC is Namecheap.
They have some VPS offerings here, I have used them before and they are stable (but not that cheap).
https://www.namecheap.com/hosting/vps.aspx

You can also check oneprovider.com and ovh.com for cheap dedicated servers. Have used both of them.

Probably lost the link, is there a graph of PoS blocks generation? It'll be interesting to look at after the fork.

The last 2 graphs here:
http://explorer.yacoin.org/graphs.htm

I even prepared a PoS block interval graph, but it's not live yet (soon).

when will craptsy return our coins?

[unvoid]

when will craptsy return our coins?

When YAC will be worth it. Currently daily volume on YAC is so little that they don't want to spend their money to pay extra to YAC service/support only because YAC community want it.

No earnings for exchange = no coin on exchange. It's simple as that.

lol yac is still one of the most profitable CPU mining coin today imho, anyway, I was wondering the same about craptsy, I twitted bigvern few days ago but still no answers, in my dashboard I can still see my YAC, but if I click on balance: https://www.cryptsy.com/users/balances#YAC they are not on the list anymore.

BTW, the deposit wallet is still there, they should just give us the chance to withdraw them somehow.

[aso118]

Cryptsy removes coins that have reversed transactions.  After block 420,000 this issue should be resolved and they should return the coin permanently.

[BitzMD]

ya coin is s till aorund

[nesic1]

they give me good idea, build exchange, people transfer money to it and you then just lock their coins, nice going, i purchase yac with ltc on craptsy and 2 days after purchase i cant withdraw or exchange since yac balance is frosen, so fu*k you craptsy

well, it's not their problem that the yac network is having security issues, tbh.

What kind of problem?

I'm still CPU mining YAC and selling on bter without any apparent problem.

easy double-spending with proof-of-stake. solved with the lastest update which will kick in around 11th feb, so i expect exchanges to re-enable trading then.

off-topic: the updater process on my block explorer crashed in unclean fashion somehow, so it's now stuck on block 398692    until the rescan finishes (like 20% as of now). it uses a lot of resources, so the explorer runs kinda slow now. i also attempted to fix it so it should not happen again.

[sairon]

not so funny fun fact: so far we had 10772 orphaned valid blocks. that amounts to ~7.5 days of lost work.

[bitdwarf]

I think there were a lot at the start, when difficulty was low, but I may be mistaken.

Yes, but I don't seem to have those in my DB. The first orphan is at height 66448 with date "Sun May 19 21:20:41 CEST 2013" - so it's 11 days after the start.
