Make an ISO Image

To make an ISO from your CD/DVD, place the media in your drive but do not mount it. If it automounts, unmount it.

dd if=/dev/dvd of=dvd.iso # for dvd
dd if=/dev/cdrom of=cd.iso # for cdrom
dd if=/dev/scd0 of=cd.iso # if cdrom is scsi

To make an ISO from files on your hard drive, create a directory which holds the files you want. Then use the mkisofs command.

mkisofs -o /tmp/cd.iso /tmp/directory/

This results in a file called cd.iso in folder /tmp which contains all the files and directories in /tmp/directory/.

Windows

VaporCD can create a copy of a CD on your hard disk and mount it as if it were the real CD:

DVD - Wikipedia, the free encyclopedia

4.7GB = 4.38GB.

Long story short - media companies / salesmen and women claim that 1GB = 1000 MB, 1MB = 1000KB and 1KB = 1000B. Of course we all know that 1GB = 1024 MB, 1MB = 1024KB and 1KB = 1024B.

So, 4.7GB = 4,700,000,000B according to the companies.

But really, 4,700,000,000 / 1024 / 1024 /1024 = 4.377GB

Snippet (programming)

Snippet is a programming term for a small region of re-usable source code or text. Ordinarily, these are formally-defined operative units to incorporate into larger programming modules. Snippets are often used to clarify the meaning of an otherwise "cluttered" function, or to minimize the use of repeated code that is common to other functions.

Snippet management is a feature of some text editors, program source code editors, IDEs, and related software. It allows the user to persist and use snippets in the course of routine edit operations.
