Re: Re: Kickstarter fundraiser for an open source, distributed, P2P worldlet based on OC

My suggestion was meant to encourage some US resident on the list to
start the pledge drive on kickstarter.com. I am not able to do it
because I am not a US resident, but I will be happy to pledge if the
project is started. I can also provide server resources and manpower.
So, any takers?

I have seen pledgie.com, which is very cool and open worldwide. I have
also created an account. However, I am reluctant to start a pledge
drive on pledgie because (besides being much less known) it does not
seem to have the all-or-nothing feature of kickstarter. This feature
is very useful to avoid launching underfunded projects, which are
usually doomed to failure.

I think this project must cost about 15.000 dollars between server and
bandwidth costs, maintenance, publicity and community management for a
year. On kickstarter, no money would be taken from pledgers if the
target funding is not reached. This is a guarantee for those who want
to do the project (no temptation to start without money) and for
donors (the money is only taken if the project is real).

Worlds do not load

Hello people!

I recently downloaded this amazing environment and started to read
about it.

I came across a bugs, though. Whenever I try to load a World taken
from Cobaltworlds.com(Space--> Load Saved from --> Local Dir), the
program either hangs or run as if I hadn't try to load another
world...

I tried this in both PC and Linux OS, same hardware. Here is the
configuration:

P4 <at> 3GHz, 2Gb RAM, Nvidia 6600 GT 512Mb, OpenGL version string: 2.1.2
NVIDIA 256.53, SbLive!.
OSes: 1. Fedora 12, custom-built kernel 2.6.32.14    2. WindowsXP SP3,
freshly installed

Thanks in advance,
Muad'Dib

Re: Worlds do not load

Re: Worlds do not load

Hello,

I saw your messages and I understand now why I can't load the worlds
from cobaltworld.com.

But the world I just created can't be loaded too..

Any idea about that ?

Thanks in advance,

Re: Re: Worlds do not load

Hi Guillaume,

I received the answer below from John Dougan, when I asked the same
question, few months ago. Hope this help.

Best Regards,

Francisco

Re: Re: Worlds do not load

I didn't know about this patches. At night I'll try to load it in an
alpha3 image.

Thank you John

Botched Batch

I'm using Win7 x64. I unzipped C:\Program Files
(x86)\opencobalt-1.0alpha3 and the batch file does nothing. I won't
get to look strongly at the batch file yet, but it would be very
useful to apply some love on 'runs out of the box'.
http://www.opencobalt.org/documentation/user-guide/launching does not
give me direction on hacking the batch file to behave. I could be
doing something wrong, I'll take a look when I'm back from errands.

I'm very interested in this technology, particularly seeing it in
common enough use it turns a Linux Apache MySQL PHP (LAMP) box into
adding a 'C' in there somewhere for Cobalt. In any case, any help on
actually getting the application to fire up would be helpful. Thank
you. :)
