2016-04-15 04:01 <wpwrak> grmbl. my server (and thus all my mail, anelok.com, etc.) is down for hours. now i find out that support isn't even quite sure how to check its status. i wonder in what sort of dungeon they may be keeping it ...
2016-04-15 04:11 <whitequark> what host?
2016-04-15 04:13 <wpwrak> almesberger.net aka anelok.com / anelok.pw and a few other names that aren't in common use. a dedicated server at amhosting.
2016-04-15 04:13 <whitequark> hm, never heard of that
2016-04-15 04:13 <whitequark> wpwrak: DocScrutinizer51: some improvement to solvespace rendering: http://fehu.whitequark.org/files/tmp/hiddenline.gif
2016-04-15 04:13 <whitequark> (and of course it can be exported to PDF just as it is on the screen)
2016-04-15 04:14 <wpwrak> (solvespace) cute :)
2016-04-15 04:14 <whitequark> improves legibility quite a bit and of course lets me export decent-ish shop drawings
2016-04-15 04:14 <whitequark> i'm nearing the point where the shop won't reject them outright and insist on redoing everything themselves in solidworks :p
2016-04-15 04:15 <wpwrak> do you have automatic measurements, like i do in fped ? i.e., measurements that are attached to model features and are updated when the construction / parameters change(s) ?
2016-04-15 04:15 <whitequark> sure
2016-04-15 04:15 <whitequark> reference dimensions
2016-04-15 04:15 <wpwrak> kewl
2016-04-15 04:15 <whitequark> they work just like regular parametric dimensions, but the direction of information flow is reversed
2016-04-15 04:16 <whitequark> right now it's not always convenient to use them though since they can only be attached to "entities"
2016-04-15 04:16 <whitequark> i.e. a curve that was explicitly drawn or derived from another curve during extrusion or lathe operation
2016-04-15 04:16 <whitequark> as opposed to attaching them to arbitrary points of interest on the geometry
2016-04-15 04:17 <whitequark> at some point i would like to derive entities from geometry, but this requires a much tigher integration of the NURBS engine with the solver
2016-04-15 04:17 <whitequark> right now the solver and the entity system lives in one corner and the NURBS engine is completely independent from it
2016-04-15 04:18 <whitequark> (and there's also a mesh engine, for tricky cases where NURBS engine does a stupid thing)
2016-04-15 04:18 <whitequark> and of course you cannot reasonably feed back the triangle mesh into the solver
2016-04-15 04:19 <whitequark> there's also that dream of not using opencascade that i have...
2016-04-15 04:20 <whitequark> currently the plan is to pluck the algorithms from opencascade, without dragging all the millions of LOC of horribleness with them
2016-04-15 04:20 <whitequark> but it'll take many months
2016-04-15 04:21 <wpwrak> pheew. that might indeed be quite a bit of work
2016-04-15 04:21 <whitequark> it's actually less work than it might look at first
2016-04-15 04:21 <whitequark> but it's a lot
2016-04-15 04:22 <whitequark> fortunately, we (m-labs) have hired a rather talented graphics programmer
2016-04-15 04:22 <whitequark> who has done the feature above and many more
2016-04-15 04:23 <whitequark> he's already done some things i haven't really considered possible
2016-04-15 04:23 <wpwrak> does the solver also work in 3D or only in 2D ? e.g., could you have it find, say, a point or pair of points that has given distances a, b, and c from three points A, B, C in space ?
2016-04-15 04:23 <whitequark> 3d
2016-04-15 04:23 <whitequark> when you work in workplane it actually uses the 3d equations for everything, but locks one of the coordinates
2016-04-15 04:23 <wpwrak> (m-labs) aah, that's how you ended up in hkg of all places :)
2016-04-15 04:23 <whitequark> (or uses a more complex equation if the workplane is not parallel to axes)
2016-04-15 04:24 <wpwrak> (3d) nice !
2016-04-15 04:24 <whitequark> well, i also considered jane street
2016-04-15 04:24 <whitequark> yeah, the author of solvespace wrote a 2d solver previously and he was dissatisfied with it
2016-04-15 04:24 <whitequark> which is how solvespace was born
2016-04-15 04:25 <whitequark> you can actually mix and match working in 3d and workplane quite easily
2016-04-15 04:25 <whitequark> e.g. you can draw a profile for extrusion in workplane but have construction lines in 3d in the same group
2016-04-15 04:25 <whitequark> it's very unobtrustive
2016-04-15 04:27 <wpwrak> sounds good. one of these days i really need to give it a spin.
2016-04-15 04:27 <whitequark> you do :)
2016-04-15 04:28 <wpwrak> hm,, still no sign of my poor little server :( support said the case was escalated to the admins as "emergency". of course, for all i know, that may be the base level ...
2016-04-15 04:28 wej has joined #qi-hardware
2016-04-15 04:33 <wpwrak> "emergency" = goes right to the trash folder; "global zombie apocalypse" = ignore; "nearby supernova explosion" = read and delete, taking no further action; "galactic collision" = send standard excuse from the BOFH files; "universe collapses into strange matter" = send customized excuse; "continuum underlying the time-space continua of the multiverses collapses" = turn it off then on again. etc.

2016-04-15 05:03 <whitequark> granted, galactic collisions are incredibly mild events
2016-04-15 05:07 <wpwrak> in terms of overall consequences or in terms of urgency ? :)
2016-04-15 05:13 <wpwrak> hmm, the joy of having an old server: "After looking at your server it appears to have a hardware failure that will not be able to be fixed until tomorrow morning due to getting the necessary parts."
2016-04-15 05:13 <wpwrak> guess the museum store isn't open 24/7.
2016-04-15 05:14 <wpwrak> let's hope it's just the power supply or such, not the disk.
2016-04-15 05:16 <whitequark> did you make backups?
2016-04-15 05:17 <wpwrak> the really critical stuff is duplicated, but scattered over numerous places.
2016-04-15 05:18 <wpwrak> also, if they set up a new machine, some of the truly ancient things (sendmail.cf and such) may need redoing
2016-04-15 05:19 <whitequark> i just roll encrypted backups onto amazon glacier every night
2016-04-15 05:19 <whitequark> it costs me like... 78 cents per month
2016-04-15 05:19 <whitequark> i don't know why amazon bothers to charge my card. i'm pretty sure the payment processor fees are larger than that
2016-04-15 05:25 <wpwrak> hmm, that looks interesting indeed. so you keep ">= 50%" (adjust for compression) of your disk free, tar.foo everything up, then push the tar.foo to amazon ?
2016-04-15 05:25 <whitequark> I use duplicity, which handles incremental backups
2016-04-15 05:25 <whitequark> and encryption
2016-04-15 05:26 <whitequark> but yeah, you do need some free space. of course duplicity is smart enough to not back up /tmp and other such caches
2016-04-15 05:26 <whitequark> like /var/cache/apt/archives :)
2016-04-15 05:26 <wpwrak> (duplicity) ah, i guess this may come in handy: https://sedden.github.io/blog/2015/11/11/backup-to-amazon-s3-glacier-with-duplicity/

2016-04-15 08:15 <eintopf> so argentinia has three
2016-04-15 08:15 <eintopf> one ractor is named "Atucha 2/Kirchner"
2016-04-15 08:15 <eintopf> isn't that the (old) president?

2016-04-15 08:16 <eintopf> ahh
2016-04-15 08:16 <eintopf> I hope we have a reactor named "merkel"
2016-04-15 08:25 <wpwrak> Chermany I
2016-04-15 08:27 <eintopf> wpwrak: with new president, do you think argentinia gets better times
2016-04-15 08:27 <eintopf> but maybe the current times are already good
2016-04-15 08:31 <wpwrak> oh yes, i'm rather optimistic about the future
2016-04-15 08:32 <eintopf> cool
2016-04-15 08:33 <wpwrak> but this year will still be bad for most people. worse than last. but the government is making sound economical decisions. it'll take a while until they produce improvements, and until then they make things worse. e.g., energy and transportation prices went up a lot
2016-04-15 08:34 <wpwrak> but they used to be absurdly low, kept that way with enormous subsidies. money that basically came from inflation.
2016-04-15 08:35 <eintopf> ah ok.
2016-04-15 08:36 <eintopf> if you asking me, I am for "wpwrak for president"
2016-04-15 08:36 <eintopf> :-)
2016-04-15 08:36 <wpwrak> naw, now i we have a government where i don't think every day that i could do a better job than them :)
2016-04-15 08:37 <wpwrak> the last one acted a bit like beavis and butthead, so ...
2016-04-15 08:39 <eintopf> I am too young to know "beavis and butthead", I know them and also saw them inside tv
2016-04-15 08:39 <eintopf> but didn't listen to it
2016-04-15 08:39 <eintopf> because, too young. I played gameboy that time
2016-04-15 08:41 <wpwrak> that's more wholesome content :)
2016-04-15 08:46 <wpwrak> anyway, the evil day-star is about to rise. time to crawl to bed.
2016-04-15 08:48 <eintopf> ok

2016-04-15 22:41 <roh> which one... qi-hw?
2016-04-15 22:41 <roh> s/be/he
2016-04-15 22:43 <wpwrak> naw, almesberger.net aka anelok.com, etc.
2016-04-15 22:43 <wpwrak> so my mails are now being queued at the respective senders, etc.
2016-04-15 22:45 <wpwrak> since the box will be all-new, i guess i should drop that ancient sendmail.cf as well. it has served me well over the last, uh, ~25 years, but sometimes it's just time for a new beginning.
2016-04-15 22:47 <wpwrak> what's the current best choice for MTAs if you don't need fancy or historical ? (UUCP, remember%the.old@days.foo, and all that)
2016-04-15 22:48 <wpwrak> well, s/best/lazy admin's/ :)
2016-04-15 23:15 <roh> wpwrak: postfix or exim
2016-04-15 23:16 <wpwrak> for maximizing laziness, which is better ?
2016-04-15 23:16 <roh> i guess it doesnt matter much as long as you use the distro foo
2016-04-15 23:17 <wpwrak> kewl. so let's see which has the best quick start guide ...
2016-04-15 23:17 <roh> which one? ubuntu/debian? go with what it gives you by default (which is either exim or postfix)
2016-04-15 23:19 <wpwrak> ubuntu server. dunno what it has as default, if any
2016-04-15 23:21 <wpwrak> hmm, this sounds useful: http://www.nmmm.nu/postfix.htm
