This is childish. Bitcoinwisdom is supposed to give neutral access to available data without any own interpretation or own judgment. If you personally don't want to see the MtGox prices then just don't look at them, click somewhere else, problem solved.

I can confirm this works.

bitcoinwisdom stopped working for me. Can anybody tell me what happened on bitfinex?

I had a short that should close at 690 and a bunch of buy orders immediately below that to go long again. Now I logged in and saw "Position #xxxxx closed @ 500.0 on wallet trading" WTF 500 I had buy orders at 690! I made a nice profit due to my short closing at 500 instead of 690 and my longs not executing which probably saved me from a margin call so now I am up 30% on my account instead of being broke, so I won't complain, but wtf has happened? Does anybody have a price chart of trades that happened on bitfinex?

I read somewhere in the bitcoinwisdom thread that bitfinex API now always returns bitfinex and bitstamp combined orderbook and volume, so its always more than bitstamp alone.

I had some more time today and tracked it down even further, actually its only the barrier=0 mount option that affects this huge slowness/speedup, I have changed my mount options back to the dafault data=ordered again (undid my changes using tune2fs and removing the boot parameter) and the only mount option remaining that makes the difference between 1 minute and 1 second is barrier=0

No, this is not true.


This was me just placing a buy 0.01111 @ 1000:

12:35:25 924.8798 0.01111
(time zone is CET)

it filled at 924.8798 and was reported correctly in the trades stream. If gox were as broken as you claim then goxtool (and probably also bitcoinwisdom and clarkmoody and others) would be completely unusable because they must use the trade messages to clean up any potential crossed-book conditions which often occur on gox due to occasionally missing depth messages.

All headlines about financial events are always composed in the following manner:

<something just happened> [as|after|despite] <something unrelated that happened at the same time>

The second part after the "as" is chosen randomly. Its sole purpose is to make it appear as if they were able to understand or explain what is going on. You will not find a single news source that would ever publish an article about a currency or commodity or stock rising or falling without the obligatory "as"-clause attached to it in the headline, no matter how absurd it may seem:

"Bitcoin drops as emerging market concerns ease"
"Bitcoin drops as Fed is cutting stimulus further"
"Bitcoin drops after disappointing Apple report"
"Bitcoin drops despite disappointing Apple report"
"Bitcoin drops as Google Doodle celebrates Year of the Horse"
"Bitcoin drops despite 6-time All-Star Lance Berkman announcing retirement"
"Bitcoin drops as Justin Bieber is charged with Toronto limo driver assault"

"Bitcoin rallies as emerging market concerns ease"
"Bitcoin rallies despite Fed cutting stimulus further"
"Bitcoin rallies after disappointing Apple report"
"Bitcoin rallies despite disappointing Apple report"
"Bitcoin rallies as Google Doodle celebrates Year of the Horse"
"Bitcoin rallies as 6-time All-Star Lance Berkman announces retirement"
"Bitcoin rallies as Justin Bieber is charged with Toronto limo driver assault"

I am suddenly experiencing extreme problems with MultiBit freezing while causing extreme Disk-IO for at least a minute until it becomes responsible again.

* Open MultiBit and wait: after 20 seconds or so it will start showing high disk-IO for one minute.
* Open MultiBit and immediately close it again: writes "saving walllet" to title bar and is frozen for a whole minute before it closes.
* Open MultiBit, click send and then click new: frozen for 1 minute with high disk io. Enter address and amount, click send: frozen for another minute, enter wallet password: frozen for another minute. First confirmation arrives: frozen for another minute.

I previously had this wallet on my old ThinkPad Pentium-M, 1.3GHz with 500MB RAM and extremely slow HDD (and btrfs!) without any problems. Now I have a 6 core AMD machine 6*3.5GHz and SATA3 HDD (ext4), running Kubuntu 12.04, completely fresh install, only 5 days old, installed latest MultiBit, opened same wallet file and these problems began. I already tried resetting the block chain (this went astonishingly fast compared to my old Laptop) but its still showing these symptoms. I tried to preload libeatmydata.so to disable fsync() but it makes no difference.

What could be causing this? It became essentially unusable. How can I help debugging or solving this problem?


Edit:
Found it. It seems MultiBit is doing something that completely overwhelms the journaling mechanism of ext4. Now I followed these instructions: http://blog.smartlogicsolutions.com/2009/06/04/mount-options-to-improve-ext4-file-system-performance/  (and also the one in the comments regarding the change to the grub config before rebooting), now my mount options are (data=writeback,barrier=0,commit=600,noatime,nobh,errors=remount-ro) and the time went down from 1 minute to 1 second!

Then it would almost look like linear anyways, so actually the linear scale would not be needed at all, it can be removed ;-)

There is only one authority that could ever be allowed to issue stuff like passports or certifications or hold elections and publish the results and this is the block chain!

The Tor project is rewarding long running nodes the "entry guard" status and once a node is elected and promoted to that status its recorded in their golbal consensus. their consensus is a fixed centralized consortium of servers run by the Tor project. We have a global consensus too, if we had the equivalent of "entry guards" it would be recorded in the block chain.

How about this: proof-of-uptime: instead of proving a sacrifice how about rewarding long running nodes or nodes that have relayed a lot of transactions for a long time with colored Satoshis to a dedicated address of this node. Upon connect the node would would sign a response to a challenge with this key/address and the other node can then look up the "trust"-level and the age of this address in the block chain.

This is only an idea. It still has to be refined, for example the SPV client needs to query all these proof-of-uptime tx for a new node (and check them against the block headers) if it has not yet seen this same node before, etc. but this is the general way I would like to see such kinds of problems be approached and not the cheap way of asking a central authority to do it for us. If we wanted a central authority we could ask the foundation to run a server for us and would not need the block chain anymore at all. Then we would have invented PayPal.org.

We are making a lot of propaganda of how useful a global decentralized trustworthy ledger is and how all kinds of important stuff can be recorded and certified there because we have finally solved the consensus problem and now we have something important that needs to be recorded or certified in a secure and trustworthy manner and the first thing Mike comes up with is invoking the government to do it for us instead of using our own cool new technology of global consensus.

Looks like Mike Hearn wants to solve the double spend problem. Maybe someone should tell him that its already solved.

This is not possible. Its not even possible to **define** this problem because you cannot come up with a definition for "actor" or "controlled". And its not needed anyways because Satoshi invented the block chain.

The problem is you need only 4 and not 10000 because Android Wallet and MultiBit connect to only 4 nodes. Someone who wants (and is technically skilled enough) to rip of people with fake nodes during large zero confirmation cash transactions (what a stupid example anyways, who on earth is doing large cash-for-bitcoin transactions with zero confirmation anyways?) can easily have 3 (or 7 or 11) friends in his gang with (anonymous!) passports to help him.

This idea is so ridiculous.

And on top of that the most dangerous and most likely enemy, the government itself, can easily fake 100,000s of passports.

Proof of work is done by miners, the problem does not exist in the frst place, thats why global consensus is established by the miners, thats what confirmations are meant for.

Yes, this is new, the tick marks are correct but not the labels. BTW it should not be called "Normal", it should be called "Linear" and the default for new users should be logarithmic since this is the only scale that actually makes sense for such kind of data.

ClarkMoody is actually grouping it wrong, see for example how goxtool (the reference for MtGox) does it. On both sides it should be summed up from the top of the book down¹ to (and including) the round level, this would then also be the same value you could read from a cumulative depth chart where it is summed up to and including that price. This means the number always represents the amount to buy (or sell) to break this price, its perfectly symmetrical.

¹) Note that on the ask side "down" (deeper into the book) actually means the prices become higher, therefore the inverse sort order and usage of the next higher round price.

Hat sich erledigt (zumindest für mich), hab nun 830€ (Euro) aufgewendet für zwei komplette AMD FX-6300 basierte Systeme mitsamt 22 Zoll und Tastatur und win7 Lizenz. Schade (und irgendwie seltsam) daß dieser Markt in Europa noch komplett unerschlossen ist. Wär jetzt 2005 und hätt ich die Möglichkeiten noch wie damals würd ichs selber versuchen.

What has a small illegal marketplace for contraband to do with registered bitcoin exchanges and payment processors? You still did not answer my question why you classify stuff like sheepmarketplace as a risk for ordinary bitcoin users or why it would be relevant at all?

And Google already has well tested and thoroughly peer reviewed Bitcoin wallet code for the Android Platform which they could integrate in any of their Apps while Apple still has absolutely nothing of that sort.

In what way is SheepMarketplace a risk to the bitcoin user (or a risk to anybody at all except the users of SheepMarketplace itself)?
