NXT :: descendant of Bitcoin - Updated Information

[jl777]

Just adding.

James - you do understand that 0.1 and 0.01 *cannot be represented in binary floating point* don't you (no matter how many bits you have)?

If you care to *read* what I linked for you the problems can (and will) occur even when you are just doing simple operations.

Anyway - you have been warned but clearly are not interested in *learning* anything about serious software engineering so I give up and would recommend *no-one* to consider your software as anything other than a prototype.

I do understand. Also, I am writing an alpha version right now for DOGE. I am far more concerned about problems regarding multisig transactions than computational dust.

If the end result is the same, what does it matter that 0.1 wasnt perfectly represented? I think I will put in the int64_t stuff and have it cross check the double precision and see if there is ever any error. Would that be acceptable engineering practice for you? I thought engineering is about understanding the problem and making decisions about tradeoffs that still solves the requirements. I dont want to overengineer, but since you are so concerned, we can run both number systems in parallel and we can see if it is ever off by one satoshi.

Announcing the first online NXT Wallet

https://wallet.mynxt.info

Features:

- Easy to use
- Access your NXT from anywhere
- Responsive layout: works in PC/Mac, Tablets and Phones
- Send/Receive NXT
- See your balance in NXT, USD and BTC

Is it safe?

We made it as secure as possible, keeping in mind that as we all know nothing in the online world can be claimed to be 100% secure.

If you want the details: All accounts are 50 random generated characters long, we use AES256 to encrypt each account address twice (once using a site-wide key and once using your master password). We also only accept SSL connections and hash all passwords (salted).

There have been discussions on the main NXT Bitcointalk thread around possibly making it even safer by doing the encryption/decryption of the account on the client side (as opposed to the server side) and we are looking into this.

Launch Promo

To make things more exciting, as a launch promotion we are giving away NXT in the following way:

• The first 100 people to create an account at https://wallet.mynxt.info and post their NXT account ID (from the mynxt.info wallet) here: https://bitcointalk.org/index.php?topic=477526.new#new will get 10 NXT.
• In addition, ONE of these 100 people will get a grand prize of 1000 NXT. The winner of the grand prize will be determined by the last 2 digits of the NXT Block ID of height 75000 (you can check the latest blocks here: http://www.mynxt.info/blockexplorer/)

Promo status report: We already have over 50 users participating in the promo, and I gave 10 NXT to the first 20 already (will send the rest today).

Block 75000 (for the grand prize) should be forged sometime around Monday or Tuesday.

[abuelau]

There is lack of support for people that want to use and implement NXT, that way we miss opportunities.

Apparently implementing NXT is not that straight forward, look at cryptsy, mintpal, atomic-trader, etc… none of them succeed without any help to implement NXT.

We cannot expect mass adoption if above persist, and nobody steps forward to either make some kind of procedure or help people out.

Another remark is that I have the impression interest in NXT is decreasing in favor of new alt-coins/clones.

How can we reestablish interest in NXT?

People won't know what hit them come April. I'll make a prediction (all in good fun) -- NXT @ $1 USD by 31 May.

Just seeing Wesley's new client and the new Nxt wallet have been fantastic additions, we have atomic trade, 0.8.0 is coming... there's been a lot of good news lately. Things are looking up!

Yes, I share this view. I think we may be in the eye of the storm right now

[CIYAM]

I do understand.

Clearly you do not.

Please just try just this out:

Code:

#define test( v1, op, v2 ) if( v1 op v2 ) printf( #v1 " " #op " " #v2 "\n" )

#include <stdio.h>
#include <math.h>

int main( )
{
   volatile double a, b, c;
   char buf[ 50 ];

   a = 13.06;
   b = 0.54;
   sprintf( buf, "%lf", a + b );
   c = atof( buf );

   printf( "a = %lf, b = %lf, c = %lf\n", a, b, c );        

   test( c, >, 13.60 );
   test( c, ==, 13.60 );
   test( c, <, 13.60 );
   test( a + b, >, 13.60 );
   test( a + b, ==, 13.60 );
   test( a + b, <, 13.60 );

   return 0;
}

When is the AE going to be fully functional?

When we r satisfied with how AE works.

Think this goes toghetter with client release, no sence to release AE when avarage Joe cant use it.

Community decides when to release AE, when it is tested enough.

the community shouldn't overreacting if devs are silent for a while or another clon appears.
atm there is only btc and ethereum to measure with. emunie is broken and i don't see any
other coin/platform atm able to deaccelerate nxt. ethereum needs the whole year to go online
so we have enough time to built the best tools infront of these competitor. it is true that we
have many loose ends now but we can link them quicker than others because they are already
there while others still in design phase.

and here is my very subjective prediction: nxt -> +3.71 USD latest until 15.08.2014

I hope so. Then I can pay my debt to the bank and will be free. 

Epic win.

Care to elaborate how you arrive the value +3.71 usd

[CIYAM]

For those interested the output of the little program I posted just before is this:

Code:

a = 13.060000, b = 0.540000, c = 13.600000
c == 13.60
a + b > 13.60

Now all we how done here is to "add" two numbers together and then compare and *bam* we are in trouble.

This was locked by an administrator. You cannot unlock it

Ha? Why would an administrator lock the topic. And I didn't even get any notifications..

[BitcoinForumator]

Looking at the top of the top NXT accounts, those with the biggest holdings. I see almost no movement of NXT and i'm thinking what are they're thinking.

What good is it if you have millions and millions if NXT in the end will be worth less than if you did something with those millions and bought something that would actually help NXT?

Isn't it better to start thinking in terms of maybe you should do something with that money because in the end 20M will be worth more than 50M because those 30M spent made a huge positive difference.

guys,

i am getting these errors .. any reason?  (but my client is working).

Just start another thread.

Also - why sell NXT on exchanges to bag holders. It's better to sell those NXT in exchange for services that help NXT. Bag holders = stagnant economy. Workers = active economy.

[wesleyh]

@CFB and others, would it be good if assets listed on exchange were somehow grouped? To bring order to the chaos. Some generic groups such as "currency", "ipo", etc..

[Eadeqa]

I do understand. Also, I am writing an alpha version right now for DOGE. I am far more concerned about problems regarding multisig transactions than computational dust.
James

This is really weird. You ask  people to check your code, and then you just go on and on not even try to understanding the problem

[nexern]

@CFB and others, would it be good if assets listed on exchange were somehow grouped? To bring order to the chaos. Some generic groups such as "currency", "ipo", etc..

yes, i have proposed to add some more fields like category some weeks ago also (also an url field to link to additional asset descriptions) but the best solution is to add this on client side.
this way the user can tag/categorize the assets individually.

ps: like bond/currency/mining contract/loan/crowd funding etc.
