Eveofwar is right, it's calculated from block shares and difficulty from the time of the block.

Yes, current block rate is pretty weird, I hope it gets better soon :-).

Thralen: You can pick block stats in XLS from there: https://bitcointalk.org/index.php?topic=48889.0 It cointains around 8000 rounds from my pool. Its not up to date, but enough to do the stats.

But I can save your time telling you there's no reason to have a bad luck on diff change. But it's your time and thus your choice .

eleuthria - lol :-)

Thralen - No, there's no reason to have "bad luck" when new difficulty come. Your observation is done from very small data sample. I remember that few months ago it looked that exactly the oposite is happening - pool has been finding many blocks after many difficulty changes with the luck like difficulty didn't changed :-).

Yes, having a lot of multi hours blocks in the line and in the time of difficulty change looks "fishy", but there's nothing wrong with the pool. Pool algorithm even dont care about difficulty change, so there's no space for some bugs in the code.

Bitcoinica is hedging itself on mtgox trading 50BTC "blocks". Of course it can be any other bot or trader, but I see bitcoinica as the most likely source.

I enjoyed his skepticism because he's watching on bitcoin from the view of "normal people". We have to leave our bitcoin cave if we want to make it successful - this was his message to us as I understood it.

Average hashrate is calculated from submitted shares in last 10 rounds. It can be explained by some connection issues or if your miner was offline for some time. Did you have some connection issues today?

Looks like cgminer messed the parsing of URL, for some unknown reason. Port 8332 is "getwork" api, ports 8401-8410 are for LP broadcasts. That HTTP header for LP in getwork response is providing full URL for 8404 port. Can you report that to cgminer author?

giszmo: Great summary! :-)

Thank you for organizing the conference, it was amazing experience for me. I met a lot of people from this forum and also a people who helped me to build or improve the pool.

I also appreciated speakers who express some criticism and talked about problems. Sometimes it's absolutely necessary to leave our Bitcoin cave and look around for different opinion of people and find some new inspiration.

During those three days I made around 10 of real-world bitcoin payments. I found it very easy and convenient. Bitcoin payments are much faster than credit cards and even than cash. I went to the local market after the conference and found that I forgot to withdraw cash, because I paid almost everything with bitcoins in last days. I hope they'll accept Bitcoins soon so I don't need to find ATM :-).

I'm also pretty happy for that experience with wifi in Hard Rock Cafe. Obviously not all wifi routers are capable to download blockchain for 50 people at the same time ;-). It was definitely mistake of Cafe staff, because we asked them for fixing wifi a day ago, but we can think about some alternative solutions for situations like this (support sending transactions over sms or over QR code, for example?).

Btw is there any "recommended minimal price" for 1000 retweets? I have no idea what price can motivate some people to retweet some of my ad. Some stats or at least recommendation would be good, like Google ads are providing :-).

evoorhees, firstly I stopped reading after second paragraph with a feeling like "oh, yet another tool for spammers". Then I had a discussion on the conference and one of my friend explained me the basic idea (exactly what's on the end on your initial post ;-) ) and I changed my mind. Yes, this is really pretty cool, I especially like that self-balancing mechanism which prevents retweeters to spam bullshits, because otherwise people will stop following them.

I'm not interested in FZB because of profit, but I think I'll still retweet something if I'll see that information useful, because I feel that Bitcoin community is lacking some information about new services. I personally didn't know about a lot of cool projects before the conference (and my misunderstanding of the FZB idea is pretty good example).

Just one "feature request". Can you remove that "#Retweet4Bitcoin #FeedZeBirds ChkStatus@ FeedZeBirds.com/l86gh" on the end of every message? Or maybe leave just a "#FeedZeBirds". Not only because long text is cutting message length a lot, but I feel people can be much more critical about that particular retweet when they'll feel that it is "for profit". It can hurt not only the retweeter, but even the message credibility itself. For now I'll probably just pick the interesting tweets and will post them by myself.

Hello,

I'm working on another alternative client Electrum, which has basically same goals like your implementation, but for desktop client (at this moment). I like your job, except this:


Is there any reason why to use some Java-specific protocol? I'm solving "ideal way how to do universal network layer" right now and thinking about some universal "Bitcoin client API" too, but I prefer platform independent protocol. I didn't found any format specification on BCCAPI (is there any?) and I'm too lazy to read Java sources (because I'm not a Java developer), but do you think there's some room for cooperation on making this protocol more universal, not Java-oriented?

I was talking with this guy in the colosseum pizzeria, he's from some economic newspaper and he was interested mainly in the mining. I tried to explain him economic aspect of the mining and about auto-regulation of the network. He looked like he catched it, however i don't know what he's thinking about bitcoin overall...


I was surprised too. It looks like pretty smart camouflage, like Potemkin's village

I can recommend pizzeria colosseum,it's very close to those pubs above and probably better for talking.and they have good wine:).they have open only to 23:30,but it's probably enough for a dinner.

I'll probably go there for a dinner and then move to brmlab(hackerspace)

genjix, give my regards to Pavol, now I finally understand why is brmlab mentioned in conference program ;-). That "after conference event" is probably also (periodic) brmlab's Bitcoin seminar planned to beginning of the next week, it will be great to have you on the board :-).

I just returned from short pub session with Mitch (wordly), Tony from bit-pay and few other guys who are already in Prague. Firstly, casascius coins are really nice and everybody wanted them too! Too sad that two people convinced me and I sold some of coins to them. Poor slush. Good thing is that I sold them for bitcoins using Bitcoin wallet on Android, my first real face2face transaction using mobile phones. It was smoother and faster than I expected!

Then, I finally saw some of prepared (and still secret) projects using bitcoin and I must see - really cool! I laughted a lot especially because of p***coin.

Now I have no doubts that conference will be wonderful event.

Litt, thank you a lot! You actually bought me a bottle of wine instead of a glass ;-).

Today my connection to bitcoincharts freezed without raising any exception. I'll need to elaborate and then I'll release fixed version. I'm also learning Qt (for working on electrum client) so I'm considering to do small homework and remake SC bridge into small app with tray icon instead of weird hacker's tool for commandline.

I think there will be few people selling them ;-). Only depends on amount, mine is limited to few hundreds USD (actually I'm selling mtgoxusd traded time ago for higher than current price, I don't want to sell at current price as I'm a bull).

Exactly. There's drop from ~60k nodes (all time history of charts) to ~40k nodes. Many people are saying that it's an indicator for bitcoin population and decreasing nodes == bitcoin rejection.

OT: I must say that I don't think so. From my neighborhood I'm the only one person who's using official client on my personal computer and it's mostly just because it's configured as "trusted node" for pool :-). Other people around me are starting to use web wallets because they have many benefits for common users (like instant access from everywhere) and also because maintaining full blockchain on personal computers and notebooks is simply annoying. Thanks to this, I believe that although count of bitcoin nodes is slightly decreasing, bitcoin population is still increasing, they just don't run official client, thus they're off the statistics.

Totally OT: As maintaining blockchain is going to be harder and harder, I believe that people will switch to lightweight clients like electrum - clients which don't handle even blockheaders, just private keys. It's great way to be almost completely safe (in contrary of web wallets) and not burn own computer while receiving transaction only once a week.
