Is this site open source? What's it written in?
The site itself is not opensource and written using django as the main web framework. I forked bitcoind to implement some custom rpc-commands, this fork is of course publicly available at github: https://github.com/TripleSpeeder/bitcoin.

How many addresses can you handle?
Currently i have a limit of 800 characters for Address input for each agent, which should be enough for 20 Addresses. But this is just an arbitrary limit, if there is demand i can increase it.

*bump*

Finally txt4coins is fully functional again!

Following the good old "eat your own dogfood"-rule payments are now handled by www.bitcoinmonitor.net.

Price has been updated to 0.035 BTC!

This sound good! Is there any source code example I can see on how to use this service?
Good point - I will add some usage examples to the support section soon.
426  Bitcoin / Project Development / [Announce] bitcoinmonitor.net - Free professional notification/payment service on: February 16, 2012, 07:48:56 PM
bitcoinmonitor.net will shutdown.

I hope to have it running 2-3 more days, but circumstances are out my control. So right now there is nothing I can do about it, and it seems unlikely that it will be back up soon.


Original post from 2012-02-16:

Ever since the ugly end of bitcoinnotify.com last december I was thinking about implementing a better notification service myself, including a secure, easy-to-use payment service. This idea kept bugging me, so over Christmas holidays i started working on it. Now, after many hours spent thinking, coding, learning and testing I think it's time for a public announcement!

http://www.bitcoinmonitor.net

Of course I know there are other services already existing, but it seems many of them offer notifications as a kind of add-on to other stuff, not really focusing on providing a decent user experience. And in general it never hurts to have a choice - especially for the area of providing payment services I consider it absolutely necessary to have multiple choices which could even be used in parallel for added security/reliability.

Important: The notification service will stay free for everybody. Of course i need to think about covering the costs for server and traffic, but this will not be done by charging the average user. One idea which might have potential is embedding advertisement into the notifications, or offering complete payment integration modules for the well-known shop systems - but this is not decided yet.

Major goals I had in mind when working on this site:
  • Usability:
    To make it easy also for non-techies to understand how the site works I introduced the concept of agents. Of course usability is a subjective matter, so if you have any improvement suggestions let me know.
  • Control:
    Full notification history - You can track each and every single notification in your dashboard, including status e.g. on the response of http callback. API access is quite high on my TODO-list, which will make it possible to setup and manage your agents via json-based http API. Also a retry-strategy for failed notifications is clearly defined.
  • Speed:
    The main point in providing payment notifications is to have them as fast as possible. So the whole architecure is event-driven - no polling anywhere.
  • Stability:
    Use existing, rock-stable frameworks and tools whenever possible. This means: Mysql and django for the core, celery and rabbitmq for task handling, YAML css framework for the layout. Especially bitcoinmonitor.net does NOT require any additional tool/database/whatever to interact with the bitcoin network. It is just a stock bitcoind with small patches applied to trigger on new unconfirmed transactions/blocks and allow retrieving of arbitraty transaction information.
  • Scalability:
    Direct benefit of using existing technology versus NIH-syndrome is scalability. If necessary each component can be moved to it's own hardware, made redundant or be load-balanced.

This is the initial public launch (well, few days ago I posted it on G+ ;-), so the site is still considered in betaphase and is not yet finished.
The layout and design is really just the default YAML template and definitely needs some beautification and improvements. The list of right now available notifications is rather short. Content and texts are probably rather clumsy. API access is only half-way done and not yet available to the public.

tl;dr:
Please checkout http://www.bitcoinmonitor.net and let me know what you think!

428  Economy / Marketplace / bitcoinnotify finally down? on: December 13, 2011, 12:53:37 PM
At least since monday morning https://bitcoinnotify.com/ seems to be down.

Somehow I expected it after following the various not-amusing threads about it's selling. Still I would have preferred to get at least a short warning to all registereed users that it will go down instead of just nothing,  not even a post here in the forum Angry

Maybe the new owner (whoever that is right now as the last thread has been deleted: https://bitcointalk.org/index.php?topic=53297.0) can shed some light on the situation? Will it come back or is it down for the foreseeable future?  (Anyway i started working on my own implementation already ;-))
429  Bitcoin / Development & Technical Discussion / Re: Problems trying to build bitcoin-qt.exe (skycoin-qt.exe) on: December 09, 2011, 10:32:56 AM
Wow.
Yesterday i cloned bitcoin from github to try a small change on the rpc commands.
Typed "make -f makefile.unix".
2 minutes later i had shiny self-compiled bitcoind.exe sitting on my disk. I could not imagine it is such a hassle to get it compiling on windows? *shakes head*
(Okay, i have to admit i did not try to compile the gui version yet)
430  Bitcoin / Development & Technical Discussion / Re: gettransaction for non-wallet transactions? on: December 08, 2011, 09:44:31 PM
Cool, got it working :-)

CMerkleTx is the class to use:
Code:
// construct COutPoint to satisfy ReadFromDisk method
COutPoint dummyOutp(hash, 0);
CMerkleTx mtx;
mtx.ReadFromDisk(dummyOutp);
mtx.SetMerkleBranch(NULL);
Passing NULL into SetMerkleBranch actually triggers reading/loading it from the transactionDB. Spent some time thinking how to obtain a CBlock* untill i realized that  Roll Eyes

Wrapped this up in some rpc glue code and got my shiny new "getanytransaction" rpc command running  Grin

Thanks for your help!

Edit:
In case someone finds this usefull - the code is on github: https://github.com/TripleSpeeder/bitcoin

431  Bitcoin / Development & Technical Discussion / Re: gettransaction for non-wallet transactions? on: December 08, 2011, 04:13:53 PM
It sounds like you have a tx hash and you want to retrieve the tx.  Yes, that should be an easy modification to bitcoind.

Yes, that's what i want to do.

Glancing at the code the current implementation is completely wallet-centric. GetTransaction() from main.cpp walks through all wallets and calls wallet->getTransaction(), and also returns wallet-specific CWalletTx object. So it does not really look like a trivial patch :-/

Is there already a patch existing somewhere providing this feature? Alternatively any hints where i should start doing my own patch are welcome ;-)
432  Bitcoin / Development & Technical Discussion / gettransaction for non-wallet transactions? on: December 07, 2011, 11:55:21 AM
Hi,

I understand that the gettransactions command only will return transactions concerning the users wallet. Is there a way to query bitcoind for any transaction, independent of the users wallet?

Thanks!

kann man auch sms empfangen?

Nein, hab ich auch bisher nicht geplant. Aber eigentlich eine interessante Idee...

Wanted to check it out, but seems to be down  Sad
437  Bitcoin / Project Development / Re: BitcoinNotify for sale on: November 11, 2011, 09:12:14 AM
This is really bad news. The service was working really good so far (using it for txt4coins.net). I hope someone will buy and continue soon.
438  Bitcoin / Development & Technical Discussion / Re: Bitcoin v0.4.0 (Linux) stale connections handling on: October 27, 2011, 09:13:01 PM
I stand corrected.
Just did the following: Start up client, wait until ~150 connections are there, disconnect & reconnect router.
=> Client starts loosing connections and stays down at 8.

Sorry for being ignorant  Wink
439  Bitcoin / Development & Technical Discussion / Re: Bitcoin v0.4.0 (Linux) stale connections handling on: October 26, 2011, 01:32:35 PM
I had linux client 0.4.0 running overnight for several times and never noticed a decrease in connections (Also getting new IP every 24hours). So indeed this looks more like a problem on your side, not a general issue.
440  Local / Deutsch (German) / Re: txt4coins.net - Betatester gesucht on: October 26, 2011, 07:55:50 AM
Nächstes Feature: SMS Massenversand!

Ab sofort kann man eine Nachricht gleichzeitig an bis zu 50 Empfängernummern schicken. Das geht sowohl über das Formular auf der website als auch über die pay-per-use API. Im Moment wird der Preis einfach als (Anzahl Empfänger * Preis einer SMS) berechnet. Auf meiner Todo-Liste steht aber schon ein Mengenrabattsystem.

Mit diesem Feature rückt das Ende des betatests näher - Technisch sind jetzt alle Funktionen da die ich geplant habe. Jetzt gehts nur noch um Bugfixing und Verbesserung der Website. Ich bin nächste Woche mehr oder weniger offline, also wird die Betaphase sicherlich noch so 3 Wochen dauern.

BTW: There is also an english thread for english discussion  Wink
