fennsplicer you're going to be in berkeley?00:47
splicerno, that's meredith00:47
splicerI showed that to a friend who is something of an authority in local hacker culture. His comment was "So, you're pissing in the meme pool now? Congratulations"00:51
splicerActually it was the same guy who pointed me to iGEM in the first place, it was alway associated to hacker culture for me... we don't really have the DIY/maker culture.01:13
splicerhere DIY is more associated to growing your own vegetables and that sort of thing.01:13

patrickmclarenyeah I'll definitely add something about the 2500 members16:19
pmetzgerah. if you are around: my advice, if you're doing something that parses a complicated grammar, is to use the tools people make available for that. I think ANTLR will generate python code at this point...16:20

-!- uniqanomaly [~ua@dynamic-78-8-80-226.ssp.dialog.net.pl] has joined #hplusroadmap16:58
pmetzgerthat seems like overkill.17:00
pmetzgertwo users on the box, just set the thing globally writable.17:00
pmetzgerchmod -R ugo+rwX the directory.17:00
gnushathe end state is what i want.. the situation is different (say, more than two users)17:00
pmetzgerI don't see how acls will help...17:00
pmetzgerwhat is your precise application?17:00
gnushaalso when you add files into it the files do not inherit the samee    permissions17:00
gnushapermission inheritance between different users that don't understand permission models17:01
pmetzgerwhat is the exact application?17:01
gnushago away17:01
jrayhawkACLs are the best way. There's also cron-based permissions fixing and wacky inotify solutions.17:01
pmetzgergo away?17:01
gnushacron seems lame for this17:02
pmetzgeracls are rarely the best solution for anything.17:02
pmetzgerinotify is probably overkill. cron every minute seems like it would probably work fine.17:02
pmetzgerbut the real question is what is being done.17:02
pmetzgerthough if you would really prefer that I leave, just confirm and I'll go.17:03
pmetzgereh, I'll just assume you meant it. bye.17:03
-!- pmetzger [~pmetzger@69.86.203.77] has quit [Quit: Leaving]17:04
jrayhawkThere are lamer approaches. For instance, you can use a filesystem that doesn't support GIDs and mount it to a specific GID and umask.17:04
gnushawhat's up with pmetzger?17:06
jrayhawkhe's been spurned :(17:07
jrayhawkI also like forcing people to use git for object storage.17:08
jrayhawkBut the feasibility of that depends on your usage model.17:09
gnushathis is one of those hopeless situations where you'd orgasm if you could even get them to use cvs17:09
gnushabut instead they are using shared ftp accounts on random shared file hosts or something17:10
gnushafor software development.17:10
jrayhawkaaaaaaa17:10
jrayhawkYou could set up inotify to git commit every time they close a filehandle.17:11

jrayhawkIs there a particular reason they're not using version control?17:15
gnushaincompetence17:15
jrayhawkTortoiseGit and TortoiseSVN, while a pain to set up, are fairly easy to use on Windows if it helps.17:16
gnushait took me over 1.5 years to get a professor to use tortoisesvn17:16
gnusha(but then he learned to love it)17:16
jrayhawkSpeaking of painful learning curves, is that Ikiwiki stuff working out for you?17:17

kanzurepack vs. code21:51
kanzureit's a tough decision21:51
fennIranian President Mahmoud Ahmadinejad inaugurated a new policy on Tuesday to encourage population growth21:53
fenn$950 per kid21:54
fenn+ $95/ye for 18 years21:54
fenn"Parents will also be expected to pay matching funds into the accounts."21:55
fenndont really get the last line21:55
fennpack now, then write code and remember what you forgot to pack21:56
fennif you brought my bathroom stuff and socks it would make me happy21:57
fenncontact lenses in there somewhere would be useful21:57
kanzureweirdest thing happened the other day21:58
kanzuremom wanted me to bring over some dirty laundry when i visited21:58
kanzureso i did.. and she found a contact lense case in the collection21:58
kanzureand she thought i was hiding some sort of affair with a woman21:59
kanzure(or a guy :-/)21:59
kanzurei didn't know they were yours21:59
fennlol21:59
fenngood thing i didnt leave my lipstick in there too21:59
fennmy new room came with a bulk package of condoms22:00
kanzurebulk package?22:00
fennwell, 2422:00
kanzureis that bulk?22:00
fenni dunno22:00
kanzuregod we're lame22:01
fenni wish i'd known you were leaving earlier so i could guilt you into bringing more stuff22:02
kanzureit was a last minute ticket purchase22:02
fenndo you still hang out at the fabratory much?22:02
kanzurei thought i was leaving early july22:02
kanzurenot during the summer22:02
kanzureway, way too hot22:02
kanzurebut i do have a key and i do hang there every once in a while22:03
fennare the fishtubs still reasonably accessible? last i saw they were on top of one of the rooms22:03
kanzurethey are still there22:04
kanzurethey are quasi-reasonably accessible with a ladder22:04
kanzuredave has hextatic22:04
fenni want to get some of the electronics (lithium batteries, sensor chips, misc components) before mid august22:05
fennthose big lithium batteries are either expensive or take randint()%5 months to arrive from china22:06

kanzurei know, i know22:11
kanzureit's terrible22:11
kanzurebut the wrapper will make it look nice and pretty22:12
fennkanzure: for step.py to ever be useful it's going to need an API definition22:12
kanzureyes22:12
kanzuretake a look at test_sphere()22:12
kanzureall that stuff is going to be abstracted away from the user22:12
kanzuremost of it is just metadata22:12
kanzurethe real beans are the product_definition_shape and advanced_brep_shape_representation entities22:13
kanzureoh wait, s/product_definition_shape/shape_definition_representation/22:14
fenndid you just massage the express file into python with vim?22:14
kanzureyes and no22:14
kanzureit's been quite an experience of random bullshitting of all sorts22:15
kanzureat one point i was writing a python file to read the file python and interject code in particular places O_O22:15
kanzurewhich is of course   the wrong thingg   to do22:15
kanzure*which is of ccccourse the wwwrong thingggg to do22:15
kanzurewtf22:15
kanzure;sdfkljadjkl;adfjkfasdjkl;fasdjk22:15
fennheh negative zero22:15
fennthat's double plus fantastic22:15
ybitkanzure: adl.serveftp.org is down ftr..22:15
kanzureybit: yes i know :(22:16
kanzureheh i have a phd student at the uni to go check out the server tomorrow22:18
kanzureso we'll see what's up.22:19
kanzurefenn: Level2API.py is pretty lame22:19
kanzurehttp://designfiles.org/~bryan/csg.py is way too basic22:19
kanzureoh that's right, the server is down >_<22:19
kanzureuh, well anyway, we need a good API structure for this22:20
kanzurewhile you're espousing on how to make it not suck, maybe i can go pack your socks?22:20
kanzureheh22:20
fennoh, i dont know that much about how STEP actually works, because i never got to read the real documentation22:21
kanzureno no i mean the abstract CAD-like API22:21
fenni just know there's 13 different ways of specifying a spline22:21
fennso this is inherently confusing22:21
fenni think something like asciidoc generated from docstrings would be a good route for making documentation22:21
kanzurefor making geometric primitives, sketches, fusions, intersections, ..22:22
fennor sphinx(?)22:22
kanzurenobody should ever have to see the stuff in step.py22:22
kanzurebut rather see stuff like "class Sphere" and "class Edge"22:22
fennhm, i guess22:22
kanzureand that namespace and API full of easy-to-use constructs is what i'm wondering about22:22
kanzurepeople are welcome to use the step.py stuff i guess but honestly they are insane22:22
fenni agree most of the boilerplate stuff should be automatic22:23
kanzureyeah, hide that in a few __init__s or something22:23
kanzurebut a weird idea hit me- what about a sphere.fuse(box) where sphere is in one context (metric units) and the other is in imperial buttloads?22:23
kanzureso maybe i'll do some unit conversion magic somewhere22:23
fenner, is that even possible? fuse?22:24
kanzureheekscad has a "fuse"22:24
fennright, that's opencascade tho22:24
kanzureand solidworks and just about everything else22:24
kanzurefuse would just mean delete the surfaces that are occluded by the intersection and stitch the surfaces at the intersection edges, or something22:25

fennSMOP22:28
kanzuresmop?22:28
kanzurefenn: this isn't step import22:28
kanzurethis is step export22:28
fenni know, but you cant specify 'fuse these together' in a step file22:30
kanzureright, you have to evaluate that command22:30
kanzurewhich i think is OK to include in an API that is wrapping around all these step-specific bullshit classes22:31
kanzurebut maybe, i agree, is not the first/primary goal to accomplish22:31
fennsimple matter of programming: used ironically to imply that a difficult problem can be easily solved because a program can be written to do it; the irony is that it is very clear that writing such a program will be a great deal of work. “It's easy to enhance a FORTRAN compiler to compile COBOL as well; it's just a SMOP.”22:32
