Progress update for today. I've found the issue with validation. I *am* generating the same stream of random numbers from the random number generator I'm using from C++'s standard library on linux and the other platforms.

The bug ended up being that the standard library shuffle operation I'm using to randomly shuffle the training images is implemented differently on linux vs OSX vs windows, which is resulting in the different output.

Looks like I need to implement my own random shuffle algorithm so I know it's doing the same thing across all the OSes. Strange thing was that originally I was getting the same answers on all of them (maybe an update to the Linux OS changed the shuffle implementation).

Should have updated apps out tomorrow which should put this issue to rest!

The assimilator is also almost complete, which will let me generate a steady stream of workunits.

Thanks!

I have two questions:
- Are you going do release source code of this new app after you fix all issues which are discovered now?
- What is expected lifetime for this new app? Will it be a relatively short project, or are you going to keep this new app up for years?

Hi Daniel,

1. Source code is already on github actually (although definitely under a lot of development):

https://github.com/travisdesell/exact

2. I expect for this (and variants of it) once working to see a lot of use for quite a few years. This will drive wildlife@home and some other interesting computer science research.

Thanks. Could you create new post in "Webpage and Application Code Discussion" with link to source for this new app and pin it? There are posts for other apps there, and it will be easy to to find it in the future when someone will need it.
