Denk doch mal logisch: Die gleiche Software funktioniert auf tausenden von Rechnern in der ganzen Welt. Nur bei dir nicht (vielleicht auch bei ein paar anderen nicht).
Wo liegt nun das Problem? Offenbar bei deiner Konfiguration. Wo genau, kann dir natürlich keiner sagen, der deine Konfiguration nicht genau kennt. Du musst also die Ursache schon selbst suchen, wir können dir nur Tipps geben, wo du suchen könntest. Mein Tipp ist: Beim Programm bitcoin-qt selbst ist der Fehler nicht, da brauchst du nicht zu suchen.

Martingale. Doesn't work.

Nuff said.

Auch wenn ich die altcoins ebenfalls nervig finde, denke ich, dass sie in diesem Forum (in einem angemessenen Unterforum, das gibt es ja) ihren Platz haben. Schließlich geht es hier nicht nur um BTC konkret, sondern auch um die grundsätzlichen Eigenschaften von Cryptowährungen, um das Verhältnis zu staatlich ausgegebenem Geld, um Marktmechanismen usw. Das passt schon.
Etwas weniger marktschreierische Werbung für den nächsten Copycat von irgendeiner scrypt-coin wäre allerdings angenehm.

Don't know - I suspect a browser or networking (firewall) issue.
If you use Internet Explorer you should switch to a really recent version or another browser (firefox or chrome).
Don't know whether internet explorer is properly supported, the Ripple client uses websockets which might not work properly in IE.

Onkel Paul

You can just buy XRP for Bitcoin within ripple :-)
Whether the exchange rate is ok to you probably depends on the amount that you want to buy, though.

Onkel Paul

Please be aware that due to the way in which the forum caches images, the dynamic price tags with btcticker won't work.
Sir Lagsalot, you should probably give the price in $ and state that current exchange rate according to some exchange is being used.

Here's a list

I'm not going to write up "a really good explanation of ripple" on the spot.
The network of validators does not depend on a central server to operate, and thus it is decentralized. However, in the current phase the main validators are operated by ripple labs.
Yet since the various exchanges run their own nodes with validators, they could ensure continued existence of the ripple network and the transaction ledger (I don't know whether they have appropriate UNL settings yet to trust each other).
This is different from the bitcoin p2p approach that is based on lots of mostly anonymous nodes - ripple nodes are not anonymous. But the network is decentralized.

Und was sagt uns das Pattern? Aussterben innerhalb der nächsten 100-200 Millionen Jahre? Könnte ich mit leben

dancupid got scammed by TradeFortress. TradeFortress claims that he was just doing this as a social experiment to show that Ripple sucks, but in fact he was exploiting people who did not understand how the trust system works in Ripple.
dancupid could get rid of the fake bitcoins by sending them back to TradeFortress (they're worthless anyway). Yeah the UI does not make that easy because you can't simply send BTC issued by a specific party, I know. I think it should be possible by sending those 4 BTC to an address that only accepts TradeFortress BTC.

@dancupid: In case you care at all, I can help you get rid of the TradeFortress fake BTC - I'll send you a PM explaining how. If you don't care for Ripple anymore, just igore it.

Onkel Paul

edit: I just found that there's a trade offer on Ripple where you can sell TradeFortress BTC for 0.001 XRP each. So getting rid of them is possible. Whether you want that or not is your personal decision.

Das sieht aber ganz eindeutig nach Netzwerk-Problemen aus.
- Hast du nach den Proxy-Einstellungen geschaut?
- Bist du sicher, dass der Rechner direkte Verbindungen zu den externen Adressen aufnehmen kann? Oder geht das nur über einen Proxy?
- Ist das überhaupt der Rechner, von dem du jetzt aufs Internet zugreifst, oder ein ganz anderer?

Gib mal auf dem Rechner im Browser die Adresse 91.198.22.70 ein (nix gefährliches, das ist die Adresse von dyndns.com, mit der man seine eigene externe IP rausfinden kann). Wenn da "Current IP Address: ..." rauskommt, ist offenbar nur bitcoin-qt betroffen - dann pfuscht irgendein anderes Programm auf dem Rechner dazwischen.

Auf jeden Fall ist das so aus der Ferne ohne genaue Informationen nicht zu diagnostizieren - und es ist ganz sicher überhaupt kein Bitcoin-Problem, sondern ein Netzwerk-Problem...

"Premined" does not make much sense in the context of Ripple, as there is no mining at all.
Yes, all the XRP in existance have been generated at the start. Ripple Labs have been very open about the way this works: They distribute reasonable amounts through giveaways so early adopters can experiment with the system. In the long run, they don't want the price of XRP to rise much (unlike BTC) but to stay low enough that transactions (which need XRP) are both really cheap and still not free to discourage transaction spamming.
They also made clear that they retained or gave to their developers most of the XRP to be sold, thereby generating revenue.

All of this has been asked and answered a number of times already. It would be really great if people read up on available information instead of spreading misinformation.

Onkel Paul

No it isn't.
You normally use the web client that's served from their site, but you don't have to (it's just convenient).
You can download the client and run it from your local computer (if you have a small web server installed) or run it from another web server anywhere. Building the client is a bit complicated, it requires the "grunt" system and node.js, and you need a fairly recent version for that. Don't know exactly which platforms are supported, ubuntu 12.04 LTS (which I use here on this computer) isn't :-(
Second, you need to connect to a ripple server. The default configuration connects to the servers operated by Ripple Labs, but you can connect to any other server instead if you like. At the moment I don't know of other publicly accessible servers though, and I did not set up a server myself, so currently I'm using their servers.

Onkel Paul

Hast du die Firewall geprüft?
Ist eventuell eine Proxy-Einstellung in der Konfiguration gesetzt, dun der Proxy läuft nicht?
Gibt es in debug.log irgendwo einen Eintrag "... addresses found from DNS seeds"?
Bei mir ist "..." meistens 106, das sind die Seed-Bitcoin-Knoten, die von den 4 DNS-Servern geliefert werden.

Onkel Paul

You can calculate for yourself - if a 1 mBTC bet has a 1-in-1000 chance of winning 800 mBTC you'll lose in the long run.
Without going into the details, on average each 1 mBTC gives you a 0.8 mBTC return. The actual chances of winning when you place a given number of bets are calculated a bit differently (you'd need to place almost 700 bets to have a 50/50 chance of winning: 0.999^693 is approximately 0.4999).

As I said, I think it's much more promising to bet on real world events (real betting) than on random numbers (gambling).
Even better is to bet on events that you can influence, but that borders on crime :-)

Onkel Paul

Gambling does not work on the average - nobody has free money to give away (of course, some sites get ad revenue and redistribute part of that to visitors, that's a bit different).
Betting might work a little better - I found that by betting on pretty certain outcomes (i.e. "bitcoin price will be over $50 on December 15") you can still make small gains in the long run - it's better than the interest paid by my bank, but not extraordinary, so I just do it for fun. Betting small amounts on real-world events is a relatively slow process, and I don't think it triggers the "gambling addiction" area of your brain...

If you're not afraid of dealing with Ripple you might check out Computing for Good. Ripple Labs is sponsoring a grid computing effort (World Community Grid) by handing out XRP for WCG points if you join their team - After just a few weeks they are already the biggest WCG team...
Since I was already interested in Ripple and had participated in another grid computing project a while ago I gave it a try, and my measly i3 CPU has already gotten me quite a few mBTC.

Die Reputation von TradeFortress, dem Initiator von ripplescam, ist auch schon ein wenig ramponiert.
Da seine eigenen Aktivitäten ein wenig mit denen von Ripple konkurrierten, kann man sich auch des Verdachts nicht erwehren, dass seine Ziele mit ripplescam nicht so ganz uneigennützig waren...

Onkel Paul

Starting from incorrect assumptions you can come to arbitrary conclusions.
So what?

Onkel Paul

If you really want to do that, you should download the whole blockchain on a computer with a faster network connection and put it onto a memory stick, then use that to give your node a head start.
Downloading the complete blockchain (a bit more than 12 GB) over your 640Kb/s link would take a little less than 2 days if you used the whole bandwidth all the time. In practice, if you let your node fetch blocks from peers it will take quite a bit longer.
Ask yourself whether doing this just out of curiousity is worth the effort and time.

Onkel Paul

It's probably possible but could maybe saturate the link.
Why would you want to do it anyway? For mining, pools are preferrable. Some wallets such as bitcoin-qt require the blockchain to be present, but other such as Multibit don't, so you could use a local wallet without being a full node. I think that would be the best option for a low-bandwidth situation.
