No it doesn't. Driver manages the video card memory. On a 4GB card you can make
a single 4gb allocation and when the memory runs out it runs out, allocation
fails. No memory goes in and out of the card without explicitly asking the
driver to do so.

With Windows 7 the video driver does not see the video card memory. Windows
implements a swap on the video card and swaps video memory in and out to system
memory behind your back. You can over commit the card. Maximum allocation is
~1gb even when the card has 4gb, if you use too much memory performance drops
suddenly. General graphic performance can be half that of Windows XP in some
situations and when swapping performance can drop to under 10% of the full
performance.

virtualbox question

2010-05-15 Thread sara fink
I installed gentoo in virtualbox. My problem is that with the livecd it
builds a filesystem partition that is very small and I don't have control on
the size. If I want to add stuff there, the space is very limited. 119mb
for /.
If I want to add modules to the kernel they need to sit under / , kernel
compilation same thing.  the /usr/src/linux is 330mb. So kernel
recompilation is out of question because it will fail with no space left.

Is there any way to increase the size of / ? or other solutions?

I am opened to new ideas.

2 options out of the top of my head:

1. a temporary fix: you can turn /usr/src into a symlink to another 
partition.


2. a permanent fix: create another (much larger) partition, and copy the 
original root partition to this new partition. find how to do this copy 
while the guest system is NOT running, and find how to tell virtualbox 
to use the new partition.

On a more fundamental level, why was Sara limited to the live CD, seeing 
that the download of the full gentoo CD is just as free as the live one? 
If the purpose of the virtual installation is more than a temporary 
experiment (which is what live versions are mostly for) might it be 
worthwhile to download the full version and do it right?

 I am opened to new ideas. 
It's been a while since I used Gentoo livecd, but what you describe sounds
very strange. If there is a small partition created by Gentoo install
process,
it's going to be /boot, which is meant only to store kernels and grub stuff.
If for some reason you really ended up with such a small / on hard drive,
you can always boot off of the live CD again, and use parted to resize it.

In general, if you want to get a real feel for what Gentoo is like, you are
better off getting minimal install CD, and following the handbook.

P.S. How is this VirtualBox question?
P.P.S If you want to talk about Gentoo in real-time, I can often be found
on #gentoo-he on irc.freenode.net.

Who is contributing to Open Source development?

2010-05-15 Thread Gabor Szabo
Hi,

do you know about any research on mapping the profile of
people who are contributing to an open source project?

I found an interesting report from 2008:
http://www.redhat.com/about/where-is-open-source/

but I'd like to know are things like correlation to
- country
- GDP / capita of the country
- freedom of speech in the country
- personal income
- living in urban or rural area
- ... (probably a few other things I cant think about now)


Anyone with better Google fu or who remembers
such research, please send me links.

regards
  Gabor

I noticed that Israel was simply not included in the survey. This does
not mean that he situation here is terrible or excellent, just that
the folks at Georgia Tech did not manage to find data that would be
suitable for inclusion, comparable, etc. It is not even clear how hard
they tried - they could have decided that 75 countries presented a
good enough sample.
