[16:47] <edmoore> rjharrison: at some point
[16:47] <edmoore> we're keen but don't have a firm date
[16:47] <edmoore> this weekend if it's ok
[16:50] <Laurenceb> hi ed
[16:50] <edmoore> yo
[16:50] <Laurenceb> ed, if I have inline asm with gcc
[16:51] <Laurenceb> what assembles the asm?
[16:51] <edmoore> the assembler
[16:51] <Laurenceb> built into gcc?
[16:52] <edmoore> yeah
[16:52] <edmoore> gcc is both the compiler and the assembler
[16:52] <edmoore> it's a whole mish mash of stuff, but basically .c goes in at one end and hex comes out the other
[16:52] <edmoore> so compiler does c -> assembler, and assembler does assembly -> hex
[16:53] <edmoore> going to dive into the bath, bbiab
[16:53] <Laurenceb> cya, thanx
[17:01] <rjharrison> sorry afk
[17:02] <rjharrison> Cool I'll keep an eye out towards the end of the week to c what the weather is doing

[18:52] <rjharrison> Evening all
[18:52] <rjharrison> It's been a bit quiet on here the last 24 hrs
[18:53] <rjharrison> Obv. we need a nice launch to stimulate everyone
[18:55] <rjharrison> I'm going to be about 4 weeks away based on current progress. Won't have much more to offer on top of the last launch only a more improved beacon. It will have internal and external temperature on it which should throw some light on how cold it gets inside the box
[19:01] edmoore (n=edmoore@pomegranate.chu.cam.ac.uk) joined #highaltitude.
[19:01] <akawaka> what kind of beacon is it?
[19:02] <rjharrison> Oh just a gps with a transmitter sending cw on 434.075
[19:04] <jcoxon> evening rjharrison
[19:47] <Hiena> Any C expert here?
[19:50] <Hiena> I'm working on an almost GPL project, one of the member the end users, is kind of "untrusted" one. And i really don't want to get ripped from my work, so i need to watermark the binary files. Any idea?
[19:53] edmoore (n=edmoore@pomegranate.chu.cam.ac.uk) left irc:
[20:01] <akawaka> Hiena: is it a large codebase
[20:01] <akawaka> your biggest problem is going to be hiding it
[20:01] <Hiena> Nop. It will be a few hundrek kB source.
[20:04] <Hiena> I need an idea, how i could point a fragments of datas to be compile a string. He is an idiot to code, but he has an urge to get easily the fame.
[20:08] <akawaka> well, you could just do: volatile unsigned char data[] = { 0x44, 0x55, etc }
[20:08] <akawaka> with a random, say 32-byte string
[20:09] <akawaka> put it in some of the files and you should be able to find it in a hexdump
[20:28] <Ei5GTB> rjharrison, you could all help me cut the red tape to get a balloon off the ground in EI
