wpwrakor cylindrical ? like this critter: http://www.digikey.com/product-detail/en/keystone-electronics/5203/36-5203-ND/31636700:03
wpwrakmay be a bit costly on the gfx, i guess00:04
whitequarknope, and has nothing to do with gfx00:06
whitequarkwe don't have lofting because the NURBS backend doesn't support it00:06
wpwrakah, pity. well, a minor cosmetic detail at this point.00:09
wpwrakwhitequark: hmm .. can i use the length of an arc as constraint ? without having to manually calculate the radius ? i.e., for an FPC on a display module, i basically have the real-life constraint  FPC_on_module + pi * bend_radius + FPC_to_connector = 36 mm  (or similar)20:46
wpwrakhaving to manage a sum of length isn't so bad, but manually converting the radius is kinda inconvenient. any nice way to do this ?20:47
whitequarkwpwrak: yes, you can20:50
whitequarkfirst, constrain a line to have the same length as the arc20:50
whitequarkthen use construction as usual20:50
wpwrakoh :)20:50
wpwrakkewl20:51
wpwraki guess i couldn't do that for the whole cable (line + arc + line) , could i ?20:52
whitequarknope but you could do three vertical lines...20:53
whitequarkthere's , of course20:53
whitequarkhttps://github.com/solvespace/solvespace/issues/7720:53
wpwrakyup :)20:56
wpwrakbut the sequence of lines also worked. amazing ! the solver can be surprisingly robust. as long as i don't bump into a chirality trap, it behaves really well20:57
whitequarkyup20:58
whitequarkand we're going to make the solver even better20:58
whitequarkright now it can choke on really large sketches, but integrating Eigen should solve that20:59
whitequark(solve, geddit)20:59
wpwrakkewl21:02
wpwrakhmm, color selection is confusing. first, the color chooser overlay is hard to distinguish from the dialog it overlays. second, it seems that i can only choose by rgb value, not by clicking on a color or moving around in the huw (?) etc. area21:04
whitequarkwpwrak: hum.21:07
whitequarkdid that break *again*? :/21:07
wpwrakmeh. sometimes it seems to take the palette field i right-click on. but not always.21:07
wpwrak;-)21:07
whitequarkARGH21:07
whitequarkit did21:07
wpwrak:)21:07
whitequarkplease file a bug about it, gtk is acting up...21:08
whitequarkI swear I fixed this like three times already21:08
wpwrakfor all i comment on, please keep always in mind that i'm at the version before the gtkmm 3.22 requirement. so i'll eventually complain about things you've already fixed.21:09
whitequarkyeah I just checked that one on master21:17
wpwrakfresh bug: https://github.com/solvespace/solvespace/issues/15421:17
wpwrakregarding the DISPLAY_TEXTWND, what shall we do ? i looked around a little for anything obvious that would cause the window to disappear right after opening it, but couldn't find anything. in any case, this doesn't seem to cause any other issue (crash or such), and once i get it to stay, it seems to behave normally21:19
whitequarkwpwrak: can you override https://developer.gnome.org/gtkmm/3.22/classGtk_1_1Widget.html#a7697fa829dc749a19347d27f9c7f5c6621:22
whitequarkthen uhhh print the event in gdb or something21:22
whitequarkthe window doesn't like *Something*21:22
wpwrakbtw, here's the OLED module: https://gitlab.com/anelok/anelok/blob/master/me4/oled.slvs21:23
whitequarkoh, that's not a raw sketch...21:39
whitequarkwpwrak: neat21:40
whitequarkbtw, have you appreciated the stippled hidden line mode yet?21:40
wpwrakyes, that one is quite nice. didn't need it here, but i found it useful when experimenting with unions and differences.21:42
whitequarkwpwrak: that one took quite a lot of effort to get right :D22:54
DocScrutinizer05damn, https://gitlab.com/anelok/anelok/blob/master/me4/oled.slvs again leaves me with a red screen, though I "solved" that for other gitlab crap already23:19
wpwraknaw, i found one bug and learned quite a bit about how far i can take the solver. so that's a good result, considering the invaluable resource of free whitequark advice :)23:19
wpwrakDocScrutinizer05: you need solvespace to visualize it23:20
DocScrutinizer05meh, obviously konqueror tries to load it23:20
whitequarkDocScrutinizer05: unfortunately solvespace files don't have any leading 0-s23:21
DocScrutinizer05but it gives me the usual red screen from that friggin progress bar, just here it doesn't vanish on ptressing F523:21
whitequarkso all kinds of crap try to treat them as text23:21
wpwrakvaliantly, the neanderthal raises his stick, threatening the approaching tanks ;-)23:21
whitequarklol23:21
DocScrutinizer05lol, don't get me started about chromium23:22
Action: whitequark gives DocScrutinizer05 a wget23:23
whitequarkan elegant weapon, for a more civilized age23:23
DocScrutinizer05I just killed a chromium process that aze 3.2GB of RAM23:23
whitequarkI literally have that as a cronjob23:23
DocScrutinizer05ate*23:23
whitequarkfor some reason chromium leaks *GPU memory* on my machine, with disastrous results23:23
whitequarkI haven't even previously considered that as possible23:24
DocScrutinizer05seems same here23:24
wpwrak"aze", pronounced "assed"23:24
whitequarkwas it the --type=gpu-process one?23:24
DocScrutinizer05when I killed the process, it shown a "sorry this page had an error displaying" OWTTE in the window and offered to reload it23:25
DocScrutinizer05can't tell anymore23:25
whitequarkthen not23:25
wpwrakchromium error messages tend to be almost uniquely unhelpful. almost, because the web pages they link to are a few notches worse23:26
whitequarkbtw did you know you can type "badidea" at any chromium error screen to bypass it23:26
whitequarkeven the unbypassable ones23:26
wpwrak;-))23:27
whitequarkthere's a joke about software somewhere here but I'm too sad to make it23:27
DocScrutinizer05http://wstaw.org/m/2017/01/13/plasma-desktopM17764.png  which happily grew from 61MB to 63MB while I just watched it23:28
DocScrutinizer0566MB23:29
whitequarkI see you also have systemd there23:29
DocScrutinizer05http://wstaw.org/m/2017/01/13/plasma-desktopj17764.png23:30
DocScrutinizer05yeah, could puke over the Alps about that23:31
DocScrutinizer05at least you can't blame me I'm a hater not knowing what he loves to hate23:31
DocScrutinizer05I hate systemd *be3cause* it's on my system23:32
DocScrutinizer05if there was an option to not have it, I'd absolutely ignore the whole pile of shit23:33
wpwrakrepent, and install devuan :)23:38
DocScrutinizer05http://wstaw.org/m/2017/01/13/plasma-desktopC17764.png  http://wstaw.org/m/2017/01/13/plasma-desktopd17764.png is the culprit23:42
DocScrutinizer05wpwrak: even devuan can't provide a desktop like gnome or kde without systemd anymore23:42
DocScrutinizer05anyway this chromium crap memleaks like med - and I thought that was just konqueror that has this problem, but actually konqueror doesn't memleak much, it just leaves "zombies" for each window you close23:46
DocScrutinizer05like mad, not med23:46
