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. James

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

I do understand.
Clearly you do not. Please just try just this out: #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? 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

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

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.

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.

@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..

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

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.
