Why I Ripped the Same CD 300 Times
Awesome read! It&#x27;s great to see someone faced with tech challenge and not back down. We need more of that.<p>For anyone interested, here are some links to the details of error-correcting codes (ECC) used on CD-ROM:

As an information theorist, I used to be able to point to optical disks as an application of my field, and be like &quot;see all that math is useful for something,&quot; but now I don&#x27;t have anything shiny to point to anymore :(
