| 04:01.43 | 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 ... |
| 04:11.46 | whitequark | what host? |
| 04:13.12 | wpwrak | almesberger.net aka anelok.com / anelok.pw and a few other names that aren't in common use. a dedicated server at amhosting. |
| 04:13.20 | whitequark | hm, never heard of that |
| 04:13.31 | whitequark | wpwrak: DocScrutinizer51: some improvement to solvespace rendering: http://fehu.whitequark.org/files/tmp/hiddenline.gif |
| 04:13.43 | whitequark | (and of course it can be exported to PDF just as it is on the screen) |
| 04:14.02 | wpwrak | (solvespace) cute :) |
| 04:14.25 | whitequark | improves legibility quite a bit and of course lets me export decent-ish shop drawings |
| 04:14.43 | whitequark | i'm nearing the point where the shop won't reject them outright and insist on redoing everything themselves in solidworks :p |
| 04:15.26 | 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) ? |
| 04:15.33 | whitequark | sure |
| 04:15.38 | whitequark | reference dimensions |
| 04:15.38 | wpwrak | kewl |
| 04:15.55 | whitequark | they work just like regular parametric dimensions, but the direction of information flow is reversed |
| 04:16.25 | whitequark | right now it's not always convenient to use them though since they can only be attached to "entities" |
| 04:16.48 | whitequark | i.e. a curve that was explicitly drawn or derived from another curve during extrusion or lathe operation |
| 04:16.59 | whitequark | as opposed to attaching them to arbitrary points of interest on the geometry |
| 04:17.31 | 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 |
| 04:17.48 | whitequark | right now the solver and the entity system lives in one corner and the NURBS engine is completely independent from it |
| 04:18.05 | whitequark | (and there's also a mesh engine, for tricky cases where NURBS engine does a stupid thing) |
| 04:18.19 | whitequark | and of course you cannot reasonably feed back the triangle mesh into the solver |
| 04:19.42 | whitequark | there's also that dream of not using opencascade that i have... |
| 04:20.02 | whitequark | currently the plan is to pluck the algorithms from opencascade, without dragging all the millions of LOC of horribleness with them |
| 04:20.09 | whitequark | but it'll take many months |
| 04:21.27 | wpwrak | pheew. that might indeed be quite a bit of work |
| 04:21.41 | whitequark | it's actually less work than it might look at first |
| 04:21.44 | whitequark | but it's a lot |
| 04:22.18 | whitequark | fortunately, we (m-labs) have hired a rather talented graphics programmer |
| 04:22.23 | whitequark | who has done the feature above and many more |
| 04:23.05 | whitequark | he's already done some things i haven't really considered possible |
| 04:23.13 | 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 ? |
| 04:23.16 | whitequark | 3d |
| 04:23.42 | whitequark | when you work in workplane it actually uses the 3d equations for everything, but locks one of the coordinates |
| 04:23.59 | whitequark | (or uses a more complex equation if the workplane is not parallel to axes) |
| 04:23.59 | wpwrak | (m-labs) aah, that's how you ended up in hkg of all places :) |
| 04:24.13 | wpwrak | (3d) nice ! |
| 04:24.14 | whitequark | well, i also considered jane street |
| 04:24.46 | whitequark | yeah, the author of solvespace wrote a 2d solver previously and he was dissatisfied with it |
| 04:24.50 | whitequark | which is how solvespace was born |
| 04:25.09 | whitequark | you can actually mix and match working in 3d and workplane quite easily |
| 04:25.30 | whitequark | e.g. you can draw a profile for extrusion in workplane but have construction lines in 3d in the same group |
| 04:25.38 | whitequark | it's very unobtrustive |
| 04:27.16 | wpwrak | sounds good. one of these days i really need to give it a spin. |
| 04:27.28 | whitequark | you do :) |
| 04:28.34 | 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 ... |
| 04:28.54 | *** join/#qi-hardware wej (~j@2a00:1768:2001:7:1::3e) |
| 04:33.23 | 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. |
| 04:53.31 | *** join/#qi-hardware sb0 (~lekernel@123202036228.ctinets.com) |
| 05:03.57 | whitequark | granted, galactic collisions are incredibly mild events |
| 05:07.21 | wpwrak | in terms of overall consequences or in terms of urgency ? :) |
| 05:13.21 | 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." |
| 05:13.40 | wpwrak | guess the museum store isn't open 24/7. |
| 05:14.25 | wpwrak | let's hope it's just the power supply or such, not the disk. |
| 05:16.00 | whitequark | did you make backups? |
| 05:17.37 | wpwrak | the really critical stuff is duplicated, but scattered over numerous places. |
| 05:18.17 | wpwrak | also, if they set up a new machine, some of the truly ancient things (sendmail.cf and such) may need redoing |
| 05:19.01 | whitequark | i just roll encrypted backups onto amazon glacier every night |
| 05:19.10 | whitequark | it costs me like... 78 cents per month |
| 05:19.36 | whitequark | i don't know why amazon bothers to charge my card. i'm pretty sure the payment processor fees are larger than that |
| 05:25.11 | 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 ? |
| 05:25.29 | whitequark | I use duplicity, which handles incremental backups |
| 05:25.36 | whitequark | and encryption |
| 05:26.18 | whitequark | but yeah, you do need some free space. of course duplicity is smart enough to not back up /tmp and other such caches |
| 05:26.27 | whitequark | like /var/cache/apt/archives :) |
| 05:26.54 | 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/ |
| 05:27.22 | whitequark | yeah |
| 05:28.12 | wpwrak | kewl. i'll look into this once my server has risen from the ashes again. |

| 08:31.49 | wpwrak | oh yes, i'm rather optimistic about the future |
| 08:32.24 | eintopf | cool |
| 08:33.30 | 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 |
| 08:34.50 | wpwrak | but they used to be absurdly low, kept that way with enormous subsidies. money that basically came from inflation. |
| 08:35.56 | eintopf | ah ok. |
| 08:36.07 | eintopf | if you asking me, I am for "wpwrak for president" |

| 23:17.08 | wpwrak | kewl. so let's see which has the best quick start guide ... |
| 23:17.08 | roh | which one? ubuntu/debian? go with what it gives you by default (which is either exim or postfix) |
