A stream of completely random bytes cannot be compressed meaningfully. One might add: "By Definition" All lossless compression schemes rely on the input data using more than one bit of data per actual "bit" of information; Lossy compression schemes (eg, JPEG, MPEG) rely on the assumption that you can throw away some real information without anyone really noticing... |

| Elaborate please ? | 01/01/70 00:00 | |
| Ram compression | 01/01/70 00:00 | |
| What kind of data are we looking at ? | 01/01/70 00:00 | |
| Further elaboration | 01/01/70 00:00 | |

| Extra bytes | 01/01/70 00:00 | |
| In that case ... | 01/01/70 00:00 | |
| Yes it can | 01/01/70 00:00 | |

| Hang on a minute | 01/01/70 00:00 | |
| Information vs. Meaning | 01/01/70 00:00 | |
| How about helping rather than ridiculing | 01/01/70 00:00 | |
| NOT ridiculing | 01/01/70 00:00 | |
| syntax error | 01/01/70 00:00 | |
| a loony replies,its all in the entropy. | 01/01/70 00:00 | |
| sparse data | 01/01/70 00:00 | |
| Run-length encoding? | 01/01/70 00:00 | |
| proper run length coding | 01/01/70 00:00 | |
| But how do you know... | 01/01/70 00:00 | |
| slight mistake | 01/01/70 00:00 | |
| By definition! | 01/01/70 00:00 | |
| go outside the box | 01/01/70 00:00 | |
| Or more RAM | 01/01/70 00:00 | |
if 256 byte not sufficient | 01/01/70 00:00 |
