That's awesome. Thanks. This should be added to the OP maybe along with that blog's link for information or in Ziggy's own words. Well the link is straight to the github source for the QT-wallet for ultracoin. I just modified it to spit out dates when the N-factor changes instead of checking the current date against the start time to get the current N-factor. Hopefully bumface or ziggy909 can verify its accuracy. EDIT: the blog post from my first calculation by hand is http://www.holynerdvana.com/2014/02/everything-you-wanted-to-know-about.html?showComment=1392690143408#c7446463924638643266 which did provide a lot of useful information.

Some of the things that I think bumface/ziggy needs to do from my point of view:

1. Explain more about the N-factor. MANY people does not know about this.

We need to know the dates of when the N-factor changes for UTC and what that implies.
It's a BIG part of UTC so I don't understand how this is not explained on the OP from day 1.
bumface, you told me you'll speak to ziggy about this 3 days ago? What happened?

I'll post my N-factor timetable again, derived from the code in https://github.com/ziggy909/ultracoin/blob/master/src/main.cpp starting at line 994. I made a little javascript loop with the same calculations starting with Ultracoins sj-time.

Code:

var sjtime = 1388361600;
var Ntime;
var l = 0;
var seconds = 0;
var s = 0;
var n = 0;
var N = 0;
var last = 8; // no output until N=9

while (seconds < 12884901888)
{
    seconds += 1;
    s = seconds;
    l = 0;
    n = 0;
    N = 0;

    while ((s >> 1) > 3)
    {
      l += 1;
      s >>= 1;
    }

    s &= 3;
    n = (l * 170 + s * 25 - 2320) / 100;
    if (n < 0) n = 0;
    N = Math.floor(n);

    if (N > last)
    {
    last = N;
    Ntime = new Date(sjtime*1000 + seconds*1000);
    //print("N-Factor :" + N + " significant digits :" + l + " leftovers :" + s + " raw N :" + n + " Seconds from start :" + seconds);
    print("N-Factor :" + N + " Date :" + Ntime.toUTCString());
    }
}

This is the output (i used a javascript console bookmarklet in firefox, it shut down the script before it got past N-factor 17)

Code:

N-Factor :9    Date :Thu, 23 Jan 2014 06:32:32 GMT
N-Factor :10   Date :Sun, 16 Feb 2014 13:05:04 GMT
N-Factor :11   Date :Fri, 28 Feb 2014 16:21:20 GMT
N-Factor :12   Date :Sun, 06 Apr 2014 02:10:08 GMT
N-Factor :13   Date :Sat, 24 May 2014 15:15:12 GMT
N-Factor :14   Date :Sat, 12 Jul 2014 04:20:16 GMT
N-Factor :15   Date :Thu, 22 Jan 2015 08:40:32 GMT
N-Factor :16   Date :Wed, 29 Apr 2015 10:50:40 GMT
N-Factor :17   Date :Sun, 14 Feb 2016 17:21:04 GMT

The next N-factor increase should be on the 28th of this month.

Here is my best guess for N-factor change dates for Ultracoin using http://www.holynerdvana.com/2014/02/everything-you-wanted-to-know-about.html?showComment=1392690143408#c7446463924638643266 this link for scrypt-jane time and then using Ultracoins sj-time + the starting offset for each level and converting from unix timestamp to a readable date.

#EDIT: this seems to match up with peoples hashrate dropping on the 16th so i think its about right.
#EDIT 2: looking more closely at the memory req re-did that section of the chart.

Code:

If it is supposed to be Feb 1st 20:00 UTC then we have about 16h 45m to go. If its another timezone, then it starts when it starts.

Quote from: Stinky_Pete on February 01, 2014, 02:04:02 AM Countdown states "Countdown ends 02/01/2014 - 20:00:00" which is what it has always been. It ends on 1st Feb at 20:00 UTC Your profile shows you at UTC, for the rest of us that are somewhere else we see a different amount of time left before launch.

It seems the countdown does not have a timezone set, so what it shows is based on local time for whomever is looking at it. -Side note, I can't believe I've been here for 3 years without posting...
