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 ...
<whitequark>
what host?
<wpwrak>
almesberger.net aka anelok.com / anelok.pw and a few other names that aren't in common use. a dedicated server at amhosting.
<whitequark>
(and of course it can be exported to PDF just as it is on the screen)
<wpwrak>
(solvespace) cute :)
<whitequark>
improves legibility quite a bit and of course lets me export decent-ish shop drawings
<whitequark>
i'm nearing the point where the shop won't reject them outright and insist on redoing everything themselves in solidworks :p
<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) ?
<whitequark>
sure
<whitequark>
reference dimensions
<wpwrak>
kewl
<whitequark>
they work just like regular parametric dimensions, but the direction of information flow is reversed
<whitequark>
right now it's not always convenient to use them though since they can only be attached to "entities"
<whitequark>
i.e. a curve that was explicitly drawn or derived from another curve during extrusion or lathe operation
<whitequark>
as opposed to attaching them to arbitrary points of interest on the geometry
<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
<whitequark>
right now the solver and the entity system lives in one corner and the NURBS engine is completely independent from it
<whitequark>
(and there's also a mesh engine, for tricky cases where NURBS engine does a stupid thing)
<whitequark>
and of course you cannot reasonably feed back the triangle mesh into the solver
<whitequark>
there's also that dream of not using opencascade that i have...
<whitequark>
currently the plan is to pluck the algorithms from opencascade, without dragging all the millions of LOC of horribleness with them
<whitequark>
but it'll take many months
<wpwrak>
pheew. that might indeed be quite a bit of work
<whitequark>
it's actually less work than it might look at first
<whitequark>
but it's a lot
<whitequark>
fortunately, we (m-labs) have hired a rather talented graphics programmer
<whitequark>
who has done the feature above and many more
<whitequark>
he's already done some things i haven't really considered possible
<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 ?
<whitequark>
3d
<whitequark>
when you work in workplane it actually uses the 3d equations for everything, but locks one of the coordinates
<wpwrak>
(m-labs) aah, that's how you ended up in hkg of all places :)
<whitequark>
(or uses a more complex equation if the workplane is not parallel to axes)
<wpwrak>
(3d) nice !
<whitequark>
well, i also considered jane street
<whitequark>
yeah, the author of solvespace wrote a 2d solver previously and he was dissatisfied with it
<whitequark>
which is how solvespace was born
<whitequark>
you can actually mix and match working in 3d and workplane quite easily
<whitequark>
e.g. you can draw a profile for extrusion in workplane but have construction lines in 3d in the same group
<whitequark>
it's very unobtrustive
<wpwrak>
sounds good. one of these days i really need to give it a spin.
<whitequark>
you do :)
<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 ...
wej has joined #qi-hardware
<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.

<whitequark>
granted, galactic collisions are incredibly mild events
<wpwrak>
in terms of overall consequences or in terms of urgency ? :)
<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."
<wpwrak>
guess the museum store isn't open 24/7.
<wpwrak>
let's hope it's just the power supply or such, not the disk.
<whitequark>
did you make backups?
<wpwrak>
the really critical stuff is duplicated, but scattered over numerous places.
<wpwrak>
also, if they set up a new machine, some of the truly ancient things (sendmail.cf and such) may need redoing
<whitequark>
i just roll encrypted backups onto amazon glacier every night
<whitequark>
it costs me like... 78 cents per month
<whitequark>
i don't know why amazon bothers to charge my card. i'm pretty sure the payment processor fees are larger than that
<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 ?
<whitequark>
I use duplicity, which handles incremental backups
<whitequark>
and encryption
<whitequark>
but yeah, you do need some free space. of course duplicity is smart enough to not back up /tmp and other such caches
<eintopf>
wpwrak: with new president, do you think argentinia gets better times
<eintopf>
but maybe the current times are already good
<wpwrak>
oh yes, i'm rather optimistic about the future
<eintopf>
cool
<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
<wpwrak>
but they used to be absurdly low, kept that way with enormous subsidies. money that basically came from inflation.
<eintopf>
ah ok.
<eintopf>
if you asking me, I am for "wpwrak for president"
<eintopf>
:-)
<wpwrak>
naw, now i we have a government where i don't think every day that i could do a better job than them :)
<wpwrak>
the last one acted a bit like beavis and butthead, so ...
<eintopf>
I am too young to know "beavis and butthead", I know them and also saw them inside tv
<eintopf>
but didn't listen to it
<eintopf>
because, too young. I played gameboy that time
<wpwrak>
that's more wholesome content :)
<wpwrak>
anyway, the evil day-star is about to rise. time to crawl to bed.
<eintopf>
ok
<eintopf>
good night

<wpwrak>
hmm, server is more sick that they expected. it'll be new hardware then ...
<roh>
be wpwrak
<roh>
which one... qi-hw?
<roh>
s/be/he
<wpwrak>
naw, almesberger.net aka anelok.com, etc.
<wpwrak>
so my mails are now being queued at the respective senders, etc.
<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.
<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)
<wpwrak>
well, s/best/lazy admin's/ :)
<roh>
wpwrak: postfix or exim
<wpwrak>
for maximizing laziness, which is better ?
<roh>
i guess it doesnt matter much as long as you use the distro foo
<wpwrak>
kewl. so let's see which has the best quick start guide ...
<roh>
which one? ubuntu/debian? go with what it gives you by default (which is either exim or postfix)
<wpwrak>
ubuntu server. dunno what it has as default, if any
