I once read that some picture archives are backing up the most important digital images in this way:
- split the image into three monochrome channels (RGB) - print each channel to a B&W silver negative - store the obtained three negatives - silver film if kept properly can last longer than 100 years - to restore the image, scan the three negatives and re-mix in a photo editor
The assumption is that the technology to scan a film negative will still be there.
Last time I looked at it, Gimp could not work with 16-bit TIFF files (it could open them, but then converting to 8-bit). This was Gimp's big shortcoming as far as serious photo editing is concerned. Perhaps the situation changed.
The bit about "normal" referring to the perspective similar for human eye is a common misconception. It has to do with lens design, not human eye: lenses shorter than "normal" are called wide angle, lenses longer than normal - telephoto.
A normal lens is a lens whose focal length is roughly equal to the length of diagonal of the imaging surface onto which it's designed to project.
But regardless of this issue, the angle of view (determined by the focal lens) has little to do with privacy. The resolution of the pictures is more important. They can "zoom in" digitally as long as the resolution allows, not necessarily optically.
I, for one, welcome this, because...

Nero using alternative API for burning

NeroLinux vs. K3b

It is worthwile to point out that NeroLinux has its own API for directly talking to the burning hardware (well, that is, the kernel interfaces). All Linux CD/DVD burning GUIs that I know of are based around the `cdrecord' package and the like (cdrdao, dvd+rw-tools, etc.). This means that all of the GUI Linux burning software are only different in the GUI part: they don't talk to the burner directly, but use a common set of tools to do the actual burning.
NeroLinux is *really* different from them in that it has its own kernel-level routines and does not rely on cdrtools and friends. While this in it self is not necessarily an advantage, I welcome the appearance of NeroLinux as a *real* alternative to the open-source burning software.
It seems like most people are missing what I think is the main point of the article: it yet again demonstrates the business nature of organized religion, and Catholic church is right on top of it.
I betcha they don't pay taxes on that ISP venture either...

I must suck at maths. ;^)
