| 11:26.32 | d-lo | _sushi_: I would say 'some value'. It would be much more useful if you tied in some of the brlcad libs and made a .g directly instead of forcing users to perform an additional conversion step. |
| 11:27.34 | _sushi_ | Then it wouldn't work without BRL-CAD |
| 11:27.47 | _sushi_ | Can you link GPL code with LGPL libraries? |
| 11:27.53 | _sushi_ | I guess yes... |
| 11:28.19 | d-lo | You can use LGPL libs in a GPL project... just not the otherway around. |
| 11:28.23 | _sushi_ | d-lo: the user can load an ascii file |
| 11:29.03 | _sushi_ | File -> Import -> ASCII Database |
| 11:29.42 | d-lo | correct, however if your code is already generating the required memory structs, then it would be super easy to make hex an MGED command and forego the import completely. Just my $0.02 |
| 11:30.24 | _sushi_ | Yes but they won't take it because it's GPL |
| 11:30.30 | _sushi_ | and I won't make my code LGPL |
| 11:30.45 | d-lo | Where does it say its GPL? I saw no lisence anywhere.... |
| 11:31.46 | d-lo | If it is GPL, you might wanna update the hex.c on the wiki. |
| 11:32.15 | _sushi_ | Ah I didn't do svn update on my home computer and then automatically rsynced old version without the GPL header again |
| 11:32.33 | _sushi_ | Now it's fixed |
| 11:33.01 | d-lo | okay. Mind if I ask why you 'won't make your code LGPL' ? |
| 11:33.11 | d-lo | Not to pressure, just curios. |
| 11:33.15 | d-lo | curious. |
| 11:33.18 | _sushi_ | Because I am giving it for free |
| 11:33.48 | _sushi_ | I want people to behave fair that means if I give it for free they should give their code for free too |
| 11:33.54 | _sushi_ | GPL requires that, LGPL doesn't |
| 11:34.30 | d-lo | Okie, thanks! |

| 12:27.38 | d-lo | _sushi_: I am reading up on Ronja. Personally, I think its pretty damned cool. But I have a question: Is range directly proportional to lense width? |
| 12:28.57 | archivist | no gain |
| 12:29.32 | archivist | width for a good lens will be proportional to gain though |
| 12:29.33 | _sushi_ | d-lo: thanks |
| 12:30.23 | _sushi_ | d-lo: right. Range is proportional to the square root of the signal strength. And signal strength is proportional to square of lens width. |
| 12:30.33 | _sushi_ | d-lo: this is however a simplification, assuming clear air |
| 12:31.36 | _sushi_ | Ronja is supposed to work in light fog, which has additional exponential relation between path travelled and attenuation |
| 12:32.25 | _sushi_ | We are talking about transmitter lens here. |
| 12:32.44 | _sushi_ | With receiver is more complicated because larger lens constitutes a large "window" that allows ambient light on the detector |
| 12:32.54 | _sushi_ | And ambient light creates noise, except in the night. |
| 12:33.15 | d-lo | heh, well that makes sense :) |
| 12:33.41 | _sushi_ | Now a larger receiver lens often has a different focal length or even may need a larger photodiode to accomodate for more blurry focus |
| 12:33.45 | _sushi_ | and then things go very complicate |
| 12:33.53 | _sushi_ | and it has to be measured using a bench |
| 12:34.19 | archivist | mirror lens could be better |
| 12:34.24 | _sushi_ | right |
| 12:34.32 | _sushi_ | the best would be large astronimical mirror |
| 12:35.03 | _sushi_ | unfortunately they are extremely expensive |
| 12:36.02 | _sushi_ | An increase in range can be also achieved by making the receiver tube longer |
| 12:36.17 | _sushi_ | That needs lens with less dioptries and they tend to have sharper image |
| 12:36.28 | _sushi_ | And longer tube means relatively less ambient light for the photodiode |
| 12:36.45 | _sushi_ | But it's impractical to have a long tube on the roof |
| 12:38.36 | d-lo | How proactical is it to have a squared off 'u' tube with mirrors at 45 degree angles inside? Cuts down on the spaced used on the roof.... |
| 12:38.51 | d-lo | Holy Bad Spelling Batman.... |
| 12:39.14 | _sushi_ | I once already thought about that |
| 12:39.18 | _sushi_ | I think it might be a practical idea |
| 12:39.37 | _sushi_ | Modern float glass mirror have very good quality regarding garage quality usage |
| 12:39.55 | _sushi_ | You could point horizontally by simply turning the pipe |
| 12:40.03 | _sushi_ | And vertically by tilting the mirror inside |
| 12:40.19 | _sushi_ | On roof you often have an access to a wall or chimney |
| 12:40.42 | _sushi_ | You could mount this even on an aerial mast |
| 12:42.23 | brlcad | some would argue that your code derives additional value of itself when it is used by others, so imposing on someone else's license makes for an unfair exchange |
| 12:42.33 | brlcad | it'd only be fair if you also used their code in yours (in which case there is no practical lgpl/gpl difference) |
| 12:43.18 | brlcad | by someone using a code, that code benefits by reuse, publicity, affirmation, etc |
| 12:43.48 | brlcad | to claim it's unfair is dubious at best |
| 12:44.10 | d-lo | _sushi_: What about having the lense focus the beam into fiber optics? |
| 12:44.42 | _sushi_ | d-lo: why? |
| 12:45.04 | d-lo | does that achieve a 'longer tube length? |
| 12:45.25 | _sushi_ | the length of the fibre doesn't count |
| 12:46.02 | d-lo | kk |
| 12:46.09 | _sushi_ | THe advantage comes from the fact that the ambient light dissipates with square of the distance from the viewing port |
| 12:46.23 | _sushi_ | And if it is captured into a fibre it just runs along the fibre and doesn't dissipate anymore |
| 12:46.47 | d-lo | So having a 'W' shaped tube would be even better than a 'U' or an 'N' |
| 12:47.29 | _sushi_ | Aha I thought you were talking about one vertical pipe with a 90 degree mirror on the top |
| 12:48.03 | _sushi_ | Well W would be better yes but it would also have to be thicker |
| 12:48.28 | d-lo | No, several bends so as to minimize the 'long tube on the roof' issue. |
| 12:48.40 | d-lo | mornin brlcad ! |
| 12:49.33 | brlcad | 'lo lo |
