We have the greatest developer, for a little while longer
https://bitcointalksearch.org/topic/m.6024236

Anyone know if BCNext will give a contract to another great developer after April 5?

Hi,

I'm running http://crypto-coins-table.com

If you have additional information NXT please update here:

http://crypto-coins-table.com/index.php?var_action=coin_details&coin_id=NXT

thanks

Its acting all wonky.
It shows I have assets, then it disappears, then reappears.
I will just code and check back later, hopefully the network will have settled down by then

The latest NRS that was released today nuked testnet. Jean Luc announced this. We need to start from scratch.

I need test nxt also: 4PZP-Z76P-BKPR-DV4LL

(that's the new address format)

Old format: 13351022221574887413

+1 Where can I donate for this?

I need lots of textNXT, it seems testnet has gone back in time

thx, i understand

HUGE BUYS!! 

I'm afraid it is  

It is not for transactions in nodecoin
It is for earning nodecoins in a pool
if three people share 1 nodecoin, and I used satoshi as base

.33333333 is the approximation that you would get using integer
.000000003333333333.... is the error rate in this case

Each allocation gets more errors.

With doubles, the error is much less than .000000003333333333 on average, usually .00000000000001

Do you rather get 000000003333333333 error or 00000000000001 error?

James

Ah, thanks for the clarification.

And just while I have you here, you both did an marvelous job on the conference (have been following you over facebook etz.) !

Another superstition?
Java is turing complete, so it can be turned into any other turing complete language
How can the language being used be such an issue. Is Sun's JRE full of bugs?

@jl777
why nodecoin don't use (or need) a minimal base unit like satoshi for bitcoin? If a minimal base unit would be use for nodecoin, then exact integer arithmetic could be use.

Because for accumulating a large dynamic range of fractions, both fixed point and floating point have imprecision
I prefer to trust Intel silicon, than some code library to do math. I also dont like to use external libraries if I dont have to. The more of the code I am familiar with, the more familiar I am with the code. That allows me to debug better

You can test this for yourself. Sum a large number of random fractions using doubles and 64 bit ints. Tell me what gets better error rate.

James

Java my worst nightmare.  Never using this coin as soon as you said java just no. never for me.

Why don't you just eliminate all this unprecise floating point arithmetic, and use fixed point instead. There are a lot of classes that do this in C, C++ and ObjC.

It should be math thing, but it becomes superstition
superstition not always good, even if it is good in some cases
math is math, you shouldnt be able to argue with math using superstition

error rate of representing 1/3 using 64 bit integer will depend on the least common denominator you use.
with floating point, the hardware deals with that

Now add 1/3, and a bunch of other fractions and some that are not fractions. With integer, did you use the right multiplier? Was the error rate better than floating point? Maybe it was, but unless you really know the dynamic range of your input numbers, odds are the error rate is better with floating point.

So to give people the most accurate allocation of nodecoins, I decided to use floating point and make sure I didnt make any errors. Any 64 bit integer implementation would at best approach the accuracy of using 64 bit floating point, in this use case.

You have to analyze each use case to know which is better to use. All things being equal, use integers.

Now, the financial guys say, divide 100 pennies three ways -> 33 + 33 + 34 = 100
They are happy that it is exact. However, I feel that is unfair as one of the three got an extra penny
For this, I am taking all this heat. But I cannot code any other way. I have to write what feels right to me.

James

Note that is testnet version. And linux version can be done, but I don't use java for my client tho.
