I am currently trying to get it running on my raspy, but when I access the frontend I get: java.lang.NullPointerException

I can click the message away but after unlocking everything is empty, no blocks, no transactions and so on.

This is due to corrupted files. Delete *.nxt and do it again.

Hmmm, can you? I never tried that. I assumed it had to be a IP address not a FQDN

yeah, it'll work. but the IP resolved by the dynamic dns must still be visible to the world, must not be behind NAT/router.

Are you sure? I just tried it here using both IP address and host name and came up with two different hallmarks:

fddcda69eeca58e5d783ad1032d080d2758a4e427881b6a4a6fe43d9e7f4ac34140063686970686 56164732e676f74646e732e636f6d640000008a2d33015cd65b85d9388aa2235ac84e33a833cdda e1c954db12edb44374c470cef372b2066cf8da20d7e96f7fad1523e76a1dab2cd36259aaa3673b2 6ad668691c19369a9

fddcda69eeca58e5d783ad1032d080d2758a4e427881b6a4a6fe43d9e7f4ac340d0032342e31333 12e3137322e3334640000008a2d33010a7def9f4266dc3061fb9c6d41a1651b164d28b1a9b6832a cfdeb8f46145d7780a4abfd5766127515b588492b557b8e19c2bce24b4e93bec79fa2c250a06336 203

Clearly the data inputted in the fields if different, but would both hallmarks still be vaild?

And it could be behind a NAT as long as the ports are open/forwarded.

put domain in myaddress in web.xml and put hallmark you generated against that domain.

then sign up at dynamic dns service provider, and have it resolve your domain to your dynamic ip.

both hallmarks are valid, but what you put in myaddress parameter must coincide with the hallmark.

Thanks that totally makes sense!

When I last looked (probably v0.4.0), it appeared that the code sent to a set of nodes sequentially, which could presumably be very fast or very slow (depending on the connect/read timeouts configured, and the state of the other nodes at the time). Is there any reason why this can't be done as parallel tasks?

Yes, parallelization is more sophisticated. Current implementation is called Nxt Reference Software. We could optimize networking by using binary protocol instead of JSON, but this would increase entry barrier for newbie programmers. The same is applied to other parts of NRS.

Maybe it would be good to have 2 types of protocols JSON for local communication
and binary for remote communication or maybe use
data compression while sending data.
For example you or the developer that would continue work on the project
could create a procedure or library to convert JSON data to binary data.
What are your thoughts about this?!

Using portforward, a dyn DNS service and updating hallmark and address in the config on every IP change should work... Inconvenient, but doable.

Nope, no need. As I just learned, create the hallmark using your Dyn DNS service host name and put that hallmark along with the hostname (not IP) into web.xml, not the IP address.

there is no need to update hallmark and address on every ip change,
you generate hallmark against a domain, you put domain as myaddress and that hallmark into config, that's all.

im not getting any connections. i probably should update my "wellKnownPeers" parameter in web.xml right? if so can anyone tell me a couple of good strong nodes to set "wellKnownPeers" with?

I proposed similar way but BCNext said that everything must be as simple as possible. He even refused to add gzip compression.

Omg I actually expected an arguement. This is a critic from a programming tutor and not a software evaluator. (hope not!) And I am sure he is really not familiar with crypto code especially bitcoin refrence client or he wouldnt criticise magically appearing numbers!

Will take me a while to climb up again, But where is a will, there is a way...

I just did a fresh install of my pack, using my instructions, and it worked. The included blockchain is healthy.

So I assume you messed up your chain files somehow. A dirty shutdown of the server can be enough for this to happen. Do it only by SIGINT/Ctrl+C and wait until it is shut down.

As a solution for now, just do "rm blocks* transactions*" and get fresh files.

Anyone else able to navigate to any thread on https://nextcoin.org? Specifically one about the Windows client? Is the site under ddos too? Supposed to be on CloudFlare but it's still not working for me.

Is it worth to run a node with around 1000 Nxt? Will I be able to forge anything thats worth it?

Yes, u'll be earning 0.0001% of all fees.

Another way of saying this is that if you run a forging node with 1000 NXT, you will earn only 1 NXT for every 1 million NXTs that are charged as fees. Thus you will "double" your 1000 NXT initial forging stake only when THE ENTIRE AMOUNT OF AVAILABLE NXT has cycled through once not as transactions, but FEES.

Maybe it's just me, but I gotta say that forging does not seem to be a very good motivation for running a node.

Yep, you should just buy $1000s of dollars of specialized equipment that can never be used for anything else and consumes a ton of power and mine bitcoins.

Ha ha ha. Here's some reading material for you:

http://www.drdouggreen.com/wp-content/Propaganda.pdf
http://www.truth-out.org/news/item/1964:fourteen-propaganda-techniques-fox-news-uses-to-brainwash-americans

Comparing something bad with something worse doesn't make the original thing less bad.

NXT nodes are needed to make NXT strong. Those nodes are only going to be stood up by people motivated to do so. I repeat my contention that forging does not seen to be a strong motivator for setting up NXT nodes when examined closely. This could be a problem. This forum exists to address to problems.

Me going out and buying Bitcoin ASICs as you suggest does not address the problem I identify. Keep thinking, maybe you can come up with a better idea.

This was sort of tounge-in-cheek. One could easily create a NXT pool similar to other currencies. Everyone pools their NXT together into one account to increase what they could forage alone. Requires extreme trust in the pool operator however.

Interesting idea. However, I believe it will be low cost of many, many Raspberry Pis and not the high motivation of many, many forgers that will ultimately make the NXT network a viable one.
