I think they may be referring to a random string of _ASCII characters_. That would be subject to compression because it is not random at the bit level. But 100:1? I have no idea how to achieve that. Marc de Piolenc Declan McCullagh wrote:
What exactly is random data? Does it have to appear to be random? Does it have to pass some set of statistical tests to be random? If a string
I'm naturally skeptical of this claim (until I can verify it for myself), but I do not believe the claim is "we can encode random data at 100:1." They seem to be talking about 100:1 lossless compression of real-world data, which is generally not random.
