NXT :: descendant of Bitcoin - Updated Information

[xibeijan]

I agree.  What's wrong with keeping it simple and using NXT?

Standard (http://en.wikipedia.org/wiki/ISO_4217) forces usage of "X??" notation AFAIK.

Not all standards need to be followed.  Does bitcoin follow this standard?

I noticed that my local copy of Nxt runs much more stable than one on VPS (88.198.210.245). I suspect this is because my local computer has much more memory available. If ur node has more than 256 Mb RAM then use the following command to launch Nxt:

Code:

java -Xms512m -Xmx1024m -cp Nxt.zip Nxt IP_ADDRESS

-Xms and -Xmx make Java VM to use more memory. Notice there is no space between "-Xms" and "512m". U can set other values instead of 512 and 1024.

Mine is only using 76mb

Does it run stable?

Anyway, Nxt looks like it has a lot of potential.  So, hats off to the developer.

I think the decentralised exchange will be challenging.  Is the developer confident he/she can actually do this?

well the latest version kept getting stuck so I reverted to V0.2.3 which was the only one I had in my bin. Its running very well actually.

My point though was that it still only uses a small amount of memory even when I start it with your suggestion above.


I did test the latest version like that but it carried on stalling while downloading the blockchain.

Its now using 34mb and running like a charm.

The memory usage seems to be slowly creeping up. Its now at 118mb.

ive been using 0.2.3 with no issues but when tried 0.2.9 it locks up on block 133 with a

Looks like Nxt client crashes coz of memory leak.

[nexern]

is there any need for a blockexplorer with some additional statistics about fees, mining etc. or will this be included into the client soon?
if it makes sense, i can built one.

Relaunch, it may pass 133th block on other attempt.

I get too many NullPointers...

That would be great if u created a blockexplorer! Look at the sources of my Nxt Slot Machine, it scans the whole blockchain - https://bitcointalk.org/index.php?topic=346189.msg3712354#msg3712354. This can help a bit.

Third block, 273 transaction fees
Got less bugs on mac, only problem was configuring the time to fit close to most peers, i suggest using the USA time, seems more close than the EU time.

I think it's memory issue. It failed to reserve a chunk of RAM for an object and now throws NullPointer exceptions. I've seen similar effect.

It uses UTC time adjusted by timezone.

How much memory is it allocated by default?

[Noitev]

Nice job Come-From-Beyond on the slot machine.

If without "-Xmx" option then 64-256 Mb.

[klee]

I think every time I have an unconfirmed I get a NullPointer..and the fee is gone!
If I get fees I don't even see them as unconfirmed at all (and I do get some fees)..

Thx, I made it mainly to test how transactions r propagated on the network. Unfortunatelly, almost noone plays it.
