How to mount ISO images
Stop burning CD/DVD’s right now, unless you really need. This is what you have to do to mount an ISO image from a CD, DVD or floppy. Make sure you have persmissions to mount (start a session as root, run “su”, or use sudo… whatever works for you)
First create a mount point, for instance:
mkdir -p /mnt/iso
Then mount the file in that directory with:
mount -o loop disk1.iso /mnt/iso
That’s all! now the content of the ISO file (the same file structure you would find in a burnt media support) is availabe in your filesystem.
Simply… Bright!

From RGB mix to rainbows, and far beyond to sunset…
Real worth watching… That’s the kind of things that reminds me how beatiful physics is.

Physics for fun
We all spent some minutes/hours/(days?) of our lives doing entertaining mind games in waiting rooms, at the beach, toilet or any place else. Among the most popular are cross words, and math games like sudoku in all it’s variants. Well, that’s fine with those, but why not to go a step further in your brain jogging . Recently I learned about this old Russian book called “Physics for entertainment” by Yakov Perelman , which is now on public domain. Read more of Physics for fun
