Monetary System / Mint Worker used up 100% of CPU on Macbook Pro
« on: January 12, 2015, 12:49:49 pm »
As the title says: running the Mint Worker on Macbook Pro makes java used up at least 100% of the CPU power eventhough the property nxt.mint.threadPoolSize is set to 1.

Macbook Spec:
Code: [Select]
Processor Name : Intel Core i7
Processor Speed : 2.4 GHz
Number of Processors : 1
Total Number of Cores : 4
L2 Cache (per Core) : 256 KB
L3 Cache : 6 MB
Memory : 8 GB

On my PC with 4 cores, the % of CPU usage corresponds correctly to the value set for threadPoolSize property. e.g: 1 = 25% to 30%, 2 = 50%, 3 = 75%, 4 = 100%.

Any idea why this is the case?

Java version:
Code: [Select]
java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)

Nxt Monetary System Helpdesk / FAQ - Minting

Frequently Asked Questions about Minting

This section is created to help people get some basic information about Minting currency units (a.k.a coins) issued within the NXT Monetary System. Please review and provide answers, or corrections thereof, in Layman's terms.

Q: What is minting?
A: It is the process of obtaining new coins by means of letting your computer do some calculations.

Q: So, I get coins while my computer does all the work?
A: Yep.

Q: Does that make me a pimp to my computer? :D
A: You can see it that way, if you like.

Q: Can I mint any coins created by the NXT Monetary System?
A: Not all coins. Only coins of type "Mintable" can be minted. It is indicated with the paper money symbol on the Currencies page. Some examples of mintable coins are ELEMS and EGOLD.

Q: Great, I want to start minting now. What do I need?
A: An account with some NXT in it and a client. Get started with NXT: http://nxt.org/get-started

Q: I don't have any NXT. Can I still mint?
A: Nope. It costs NXT to mint. Ask around for some NXT :D

Q: I noticed that my account cannot Forge because it says that my effective balance is 0 and something about 1440 block confirmations. But I do have some NXT in my account? What gives? Does it mean that I cannot mint?
A: It takes approximately a day after creating and announcing an account to get 1440 block confirmations. But worry not, you can start minting right away! :)

Q: Can I mint and forge at the same time?
A: Sure, minting and forging are completely independent. (thx, Lyaffe)

Q: Can I mint with one account and forge with another account at the same time?
A: Yes, you can. You can also forge with multiple accounts while minting with multiple account. (thx, Lyaffe)

.. this is an ongoing list of Q&A ..

UNITY / The current state of the TOKEN asset
« on: December 08, 2014, 02:45:04 pm »
Dear James,

I've bought TOKEN a while ago and it seems that I've missed the announcement on BTT, Sept 28th, about the conversion of this asset into SuperNET.
Redeem TOKEN for SuperNET
If you have TOKEN on NXT AE, send it to: NXT-7Y5B-J8LQ-SL5P-3ULFL (alias: RedeemTOKEN)
It will be converted to SuperNET and sent back to your account within 24 hours. It is done via a manual process run by valarmg
source: https://bitcointalk.org/index.php?topic=762346

The question is now, what should I do with this asset? The last transaction on the abovementioned account is a message from someone who is asking where his/her SuperNET assets are apparently after they are sent for conversion. I wouldn't want to just send my TOKEN there now, would I?

Has TOKEN lost its value and become a vapor-asset and should I just accept that my NXT is lost with this asset?
Or is there any other way for me, and other TOKEN asset hodlers for that matter, to somehow have TOKENs converted into SuperNET (or even better UNITY) and regain its value?

Thanks in advance.


General / Account with negative balance, and it isn't the Genesis
« on: May 18, 2014, 12:42:11 pm »

It isn't the Genesis account. So, what's the deal with that? How is it possible?

Nxt General Discussion / Ideas for the NRS Asset Exchange
« on: May 13, 2014, 04:27:21 pm »
Currently, there is a warning on top of the page when duplicate asset name(s) is/are found. This is a really good move by the developers.
Warning: There is 1 other asset with the same name in the asset exchange. Please make sure you choose the right one. Look at the account and asset id for confirmation.
Maybe it is also an idea to show similar warning when ambiguous/similar asset names are found as well?

This is practically achievable by measuring the difference between two strings; it can be as simple as Regular Expression comparison or a more complex comparison e.g. by using the Levenshtein distance.

Here is an implementation I use to get the Levensthein Distance leveraging the StringUtils from the Apache Common Lang library:
Code: [Select]
 * Returns the Levenshtein distance between two Strings.
 * Greater number means that the two strings are more likely to be different. 
public double getLevenshteinDistance(String string1, String string2) {
    if (string1 == null || string2 == null) {
        return 0.0;
    // We can pre-process the Strings here (or outside this method) before comparing them
    // For example to ignore case sensitivity or a certain set of characters/symbols, etc
    // string1 = filterString(string1);
    // string2 = filterString(string2);

    // If the greater length of the two strings is equal to zero then 
    int longestStringLength = Math.max(string1.length(), string2.length());
    if (longestStringLength == 0) {
        return 1.0;

    int distance = org.apache.commons.lang.StringUtils.getLevenshteinDistance(string1, string2);

    return (longestStringLength - distance) / (double) longestStringLength;
On a side note, this method can be quite expensive.

Another idea I have in mind is to have some kind of Trollbox (by integrating the current NXT Messaging system) at the top of the Asset page so people can comment on the Asset. Perhaps, attaching the Asset Id at the beginning can be used to classify messages belonging to an asset. e.g.:
@asset18128686802152832026 This is a message sent to the Nxttycoin trollbox

So, what do you guys think?

I also really support the idea of having some kind of official addons system for the NRS so people can customize and personalize their clients according to their need. This is also to allow the horizontal development of the NRS; people an develop addons they deem to be useful (or not at all!) while core NXT developers can still focus on the main functionality of the NXT protocol.
