Guess digbtc is just massively unlucky. Estimated network hashrate is ~95Gh/s and the last 60 blocks were ~120s/block average -> another 30% or so diff decrease at block 19200 (= in about 2h or so at current hashrate).

ITT: people think mining 6 1-minute blocks in a row is as difficult as mining 6 10-hours blocks in a row
Unless I missed something, then that's correct, but only if you interpret it in a certain way.
With the same relative hashpower vs. the rest of the network, over the same # of blocks, chances of finding X blocks in a row are the same, doesn't matter if avg. time/block is 10 seconds or 10 days.
But... wouldn't a theoretical attacker care more about how much time it takes to get a successful double-spend instead of how many blocks?

Similar things are possible with BTC so not sure of the relevance to only SC? Things need to be done to ensure network balance, both SC and BTC are powerless in that regard. Howeer like I said SCGuild is concerned with such things and I'm sure he would realize he would face consequences if he attacked peoples investments. Other pools, who knows, there has been open talk from people like LukeJR (elegius owner) to run malicious attacks on IXCoin. So obviously this kind of behaviour isn't unheard of when it comes to pools.
No, they're not. Do the math.

They don't even have to turn off mining
1. Pull a mining cartel attack and fork the chain when another miner finds a block.
2. Start fucking with block timestamps.
3. Huh.
4. Near-infinite number of blocks!

If you had ever looked at the ugly state the Bitcoin code is in (and the inherent issues in it) you wouldn't be thinking it's fit enough to run millions of dollars worth of transactions a day.
Where did I say that?
Quote from: CoinHunter
It's like someone turned in a highschool assignment and everyone else went "well that works" and off they went.
Which pretty much describes the "development" style of Satoshi and other early devs.
Quote from: CoinHunter
I mean, which "designer" decided to start dumping GUI and other settings in wallet.dat ?
I'd have to check the commit logs, but I noticed that long ago and just shrugged, as compared to other *cough* "tiny issues" that's a pretty trivial one.
Quote from: CoinHunter
Do they know there is a .conf file for this?
No, I'm pretty sure the core devs never noticed there was one. Or was that a rhetoric question?
Quote from: CoinHunter
Where is at least some attempt at backing up wallet.dat's which are worth tens of thousands?
./bitcoind backupwallet filename_to_save_backup_as.
Quote from: CoinHunter
Is it really the mantra that if the power goes off and your wallet.dat was being written to that it's your fault for not running some sort of sophisticated backup system for it?
If your system corrupts a transactional BDB database on power loss, it is broken. And no amount of trickery gets you 100% around OSes/ddisks lying about flushing buffers.
Quote from: CoinHunter
Is it that hard to always have a backup file there (a single copy command) ?
Actually, yes. Backing up a live journalled DB properly is not trivial (the current backupwallet cheats by waiting for all accesses to stop, then flushing the logs and backing up the main datastore).
Quote from: CoinHunter
These type of things are standard for bulletproof applications that customers have to use, anyone with experience in the industry would see it in a second.
Wow, really? *rollseyes*
Quote from: CoinHunter
This is only the tip of the iceberg.
Yep, as you addressed only current user-visible issues but ZERO of the major issues in the core.
Quote from: CoinHunter
I have to laugh at the trolls who can't program and don't understand how awful the situation is for BTC at the moment.
Agreed.
Quote from: CoinHunter
Satoshi had some great ideas, but he wasn't a good programmer, and since he left barely anything has been done with the code.
Agreed on the part about satoshi, but there's been pretty constant improvement
Quote from: CoinHunter
The client has stagnated, badly and nearly no one wants to touch it.
Yep.
Quote from: CoinHunter
So keep the false worship up and let's see how deep people like you can keep digging the Bitcoin hole.
What false worship? Stop making shit up. I'm saying the current devs are doing pretty well at trying to sort out the mess and get a maintainable codebase instead of adding cosmetic changes and calling them "great improvements".

BTW, have you figured out the tiny problem that SCs (and i0s, and soon IXs) difficulty adjustment algo creates when faced with a attacker with majority hashpower yet?
266  Alternate cryptocurrencies / Altcoin Discussion / Re: [ANNOUNCE] SolidCoin - new and improved block chain. Secure from pools on: August 30, 2011, 09:05:05 PM
Yeah, unit tests, test suites, ... who needs that shit for a network handling $M of transactions daily? Just focus on adding features to the GUI! *facepalm*
267  Alternate cryptocurrencies / Altcoin Discussion / Re: [ANNOUNCE] SolidCoin - new and improved block chain. Secure from pools on: August 30, 2011, 08:59:15 PM
Just a small hint, the new diff algo makes a 51% attack *really* profitable, I'll leave it to you to figure out why.

Pretty sure I fried one of those with 4*HD5770 (stock V, OCed to ~1000/300).
Replaced it with a AeroCool E85-700 (HEC-700TE relabel).

I really liked the first part of this one: https://github.com/ixcoin/ixcoin/commit/a489c4b0a4bf57a4c8807995cf806fd666760135
270  Alternate cryptocurrencies / Altcoin Discussion / Re: New Ixcoin fork -> I0coin on: August 29, 2011, 09:27:13 PM
Yes. Solo it only reports 1 accepted/rejected when it finds a block (or finds a stale block solution...).
271  Alternate cryptocurrencies / Altcoin Discussion / Re: New Ixcoin fork -> I0coin on: August 29, 2011, 08:31:04 PM
Gui client works fine for solo mining if you start it with -server or put server=1 in your i0coin.conf (don't forget to also set rpcuser and rpcpassword)
just tested the new i0coind on win7, also works
272  Alternate cryptocurrencies / Altcoin Discussion / Re: New Ixcoin fork -> I0coin on: August 29, 2011, 08:26:50 PM
Hmm, tested the gui client in win7 here, works fine except for some weird graphics glitch in the background of the toolbar area.
273  Alternate cryptocurrencies / Altcoin Discussion / Re: New Ixcoin fork -> I0coin on: August 29, 2011, 08:21:28 PM
Hmmm... wild guess... it might not be showing unconfirmed rewards? (stopped mining @ bitparking ~block 15300)
274  Alternate cryptocurrencies / Altcoin Discussion / Re: New Ixcoin fork -> I0coin on: August 29, 2011, 08:17:11 PM
Hmmm, on "bitparking pool seems unlucky"...
Blocks Found   24
Balance   1269.575216314
275  Alternate cryptocurrencies / Altcoin Discussion / Re: New Ixcoin fork -> I0coin on: August 29, 2011, 08:09:12 PM
Okay, here's the gist of the new retargeting rules.

target time per block is 90 seconds.
difficulty is adjusted every 120 blocks (= 3h nominal).
upward difficulty adjustment is roughly:
 +11% if avg time/block over the last 120 blocks was < 30s
 +6% if avg time/block over the last 120 blocks was < 60s
 +3% if avg time/block over the last 120 blocks was < 90s
downward adjustment if time/block is > 90s is proportional and limited to /4.
= the same limiting algo as solidcoin, just over 120 instead of 240 blocks.
276  Alternate cryptocurrencies / Altcoin Discussion / Re: New Ixcoin fork -> I0coin on: August 29, 2011, 06:10:40 PM
Okay it appears my old wallet with 50 i0coins does not seem to confirm with the block chain. But when I create a diff i0coin address with same wallet file in the folder and run the my miners on it it confirms.

Any ideas?
You old wallet does not confirm? what does that mean?
If it's a send stuck at 0/unconfirmed it should confirm eventually.
If it's a receive stuck at 0/unconfirmed... it'll probably be stuck at 0/unconfirmed until the user that sent it upgrades (detailed reason: a client will only resend a transaction after it has seen a new block not containing the tx. old clients don't see any new blocks -> they won't resend tx.)
277  Alternate cryptocurrencies / Altcoin Discussion / Re: New Ixcoin fork -> I0coin on: August 29, 2011, 05:19:34 PM
Hmm, tried restarting the client? You might've gotten a bit unlucky and only connected to nodes running the old version (which doesn't pass along the new-rules blocks).
278  Alternate cryptocurrencies / Altcoin Discussion / Re: New Ixcoin fork -> I0coin on: August 29, 2011, 05:15:23 PM
I installed the new Windows client but it's still showing a difficulty of like 16K or so.  And Help->About still says 0.3.25beta IIRC (I'm at work now, so I'm going by memory).  Am I still running the old version?
Installed? it's just a zip containing the client and daemon exes.

280  Alternate cryptocurrencies / Altcoin Discussion / Re: New Ixcoin fork -> I0coin on: August 29, 2011, 02:31:31 PM
Yep. existing wallets should work fine, same for existing blk001/blkindex and... really... everything.
