anyone know how to un-enet-range-coder-ify a hex network dump? afaict it's not really possible from a partial dump? But either way, you'll need to manually compile something that uses the enet range coder from the library itself. The interface is exposed in enet.h iirc. Not exported in the python bindings though. |
| 10:14:02 | notafile | thought you were here before wow |

| 10:14:41 | notafile | it's a giant macro soup with macros in macros |
| 10:14:51 | Altafen#6776 | thats what i was afraid of |
| 10:15:20 | notafile | someone didn't know about that compilers inlinine functions or something |

hm, I'm getting CORS error, I wonder what's up with that wow I'm an idiot. The request to walladge.net was blocked by uMatrix |

thats what i was afraid of I think another thing here is that the range coder uses the data sent over the connection to dynamically change the encoding |
| 12:23:41 | notafile | so you need to listen to a stream from the start |
| 12:24:03 | Altafen#6776 | yeah |
| 12:24:05 | notafile | probably easiest to do the logging from inside the server... |
| 12:24:08 | Altafen#6776 | had a few ideas |
| 12:25:26 | notafile | you could keep logs in a file and then rotate it say every 5min |
| 12:25:26 | Altafen#6776 | log inside server (to ramdisk), and make sure it flushes before processing anything
use iptables TEE or something to send packets to a duplicate server which only does logging |
| 12:26:39 | notafile | well you really only need logs for when it crashes right |
| 12:27:12 | notafile | any coredumps so far btw? |
| 12:27:46 | Altafen#6776 | nope |
| 12:34:54 |  Sonicscream | Da heck is a range coder |
| 12:36:33 | Sonicscream | Lossless data compression? |
| 12:38:02 | Sonicscream | Yet another thing I've never heard of. 😂 |
| 12:43:52 | notafile | it's a variant of arithmetic coding |
| 12:44:28 | notafile | wikipedia has a great explanation |
| 12:45:22 | notafile | it's a really neat concept |
| 12:53:55 | notafile | the full name of the enet coder is a PPM(2) adaptive range coder. I somewhat understand these things on my own but the full combination especially with the code breaks my brain. |
| 12:54:51 | notafile | PPM(2) basically just means that it predicts the probability of the next symbol based on the previous two |
| 12:57:02 | notafile | that prediction is then used for the range coding |
| 12:58:39 | notafile | (I assume) |
