FEAD Compressing Compressed Files by 50-75%?

An anonymous reader asks: "I just installed Acrobat Reader and found that it was using FEAD which claims - 'FEAD© Optimizer© significantly reduces the size of application programs on average by 50% (in some cases up to 75%, depending on the specific software), even when they are already compressed with common compression technology like ZIP or CAB.' . It seems that they optimize each application individually at thieir labs. But an average of 50% compression on already compressed binary files seems to be too good to be true. Anyone familiar with how someone may be able to achieve this?"

    It's decompressing the file that's hard.

    You can compress all your files down to a single bit using this patented two step process:

    1. Discard all zeros.
    2. Use one to represent any length sequence of ones.

    This is as reliable a compression scheme as most backups to tape I've ever seen, and you can fit a huge number of files onto a single floppy.

      Thats too easy.

      First, you expand the 1 to the requisite number of 1s:
      1 -> 1111111

      Then, reinsert the 0s:
      1111111 -> 1101101001001

      Thus, 1 -> 1101101001001

      It may be difficult to read, but it sure is easy to FEAD© !!!

    > Similar things could be done for other file types: Removing quotes [...]

    When I have files with lots of quotes in them I reduce the size by using single quotes instead of double quotes.

  7. I have a better algorithm by Skim123 · · Score: 2, Funny

    I have a far superior algorithm in both time and space complexity. Start with 1. Then simply transform it to the requisite number of 1s and 0s, a la 1101101001001. Bah to your two-step process. :-)
