genehacker“We have a published protocol for describing changes to the ride—it’s built on Git3D’s system for marking up and syncing three-dee models of objects; it’s what we used all through the Kodacell days for collaboration. The way you get a ride online is to sync up with our version-server and then instantiate a copy. Then any changes you make get synced back and we instantiate them. Everyone stays in sync, give or take a cou00:30
ybitsounds like a love story00:30

ybitas long as you remember what you skimmed...00:34
kanzurejasonwohlfahrt: yeah if you're serious about it, keep a spreadsheet with a list of the files you've read00:35
ybitwhen skimming, i tend to forget to easily00:35

xp_prghow come a dvd laser cannot be used to do micro fluidic etching on a dvd?15:20
nshbecause the laser only changes the colour of a dye15:29
nsh(according to) http://osdir.com/ml/diybio/2009-11/msg00248.html15:29
nshi wonder if you could formulate a light-activated etchant15:34
tim_xp_prg: in other words, "writable" CDs and DVDs are never etched.  Only 'darkened' by the laser.  Like paper that's charred, but not burnt through.15:34

genehackerblue light activated resin damn16:36
genehackerI didn't even think of that16:36
genehackerblu-ray isn't cheap but HD-DVD is...16:37
genehackerusing a DVD burner as a spin coater sounds like a messy proposition16:38
kanzurefenn: net will be slow for a few moments16:38
fenngotta make the mess somewhere16:38
genehackerusually you do it in a spin coater that closes up16:39
fenndvd drives close16:39
fennalso you could use the setup for dna synthesis16:39
genehackerso you'd spin coat a CD?16:40
fennsome disk shaped substrate16:40
genehackersilicon shaped like a CD?16:40
fennwho said anything about silicon16:40
genehackerwhat would you be spin coating and why?16:41
genehackerwhat material would you be spin coating16:41
fennwhatever cd's are made from, probably16:42
fennmicrofluidics was the initial conversation topic16:42
tim_meh.  why wreck the DVD drive using it to spin coat?  A $2 12v hobby motor (or one salvaged from almost any household gadget) will spin a CD just fine.  Enclose it in a cardboard box. 16:42
fenni could see lots of uses for an automated pattern depositor thingy16:42
fenntim_: the dvd drive already has fine control over speed up to the cd's breaking speed practically16:43
fennand it has a laser that focuses on the surface, position control to 1 micron, et etc16:43
tim_fenn: that laser isn't going to be useful long if you're flinging goop around with the same drive.16:43
fennyeah i havent really figured that out.. maybe some kidn of 'eyelid'16:44
tim_fling the goop with a cheap motor, then place the disc in the drive.16:44
genehackerhow about a plastic box?16:44
fennyou have to make modifications to add the goop anyway16:44
fenntim the dna synthesizer requires 4*number of bases in the sequence16:44
genehackerhmmm...16:44
genehackercyranoacrylate can be vapor depositted on to surfaces..16:45
fennso that many times ptting it in the drive, taking it out, putting in spin coater,... lots of room for error and a pain in the ass16:45
kanzurehttp://www.ksc.re.kr/kcnr/Presentations/30thGNR/30thGNR_MIPark.pdf16:45
fennmuch rather have it completely automated, even if it requires modifications to the drive16:45
tim_sounds like you'd be better off building a custom machine anyway.  It would be challenging to modify a modern CD/DVD drive to cope with random crap being flung around inside it's case.16:46
fenntim_: have you been reading the replab mailing list?16:46
genehackerperhaps by shinning some UV light one could pattern cyranoacrylate on a surface and use it like a photoresist16:46
tim_fenn: nope16:46
fenncyanoacrylate hardens in air though16:47
genehackeryou could do it like you do finger print fuming16:49
genehackerthough one might need some sort of initiator16:50
genehackeranyway if this is for making microfluidics it'd better to go with the shrinky-dink route16:52
genehackerone group was able to get the shrinkage right by shrinking them fast16:52

kanzureQuantumG: i was wondering if you would be willing to help me on a few tasks, actually17:48
QuantumGwhat ya got?17:49
kanzurehttp://adl.serveftp.org/lab/opencascade/solidworks_source_structure.txt17:49
kanzurei've been looking into some DLLs17:49
kanzurei want to use some reverse compilers but i can't seem to find any :)17:49
QuantumGya, they don't exist.. it's still mostly a manual process17:50
QuantumGhow many dlls and how big?17:50
kanzurethat's 5 MBs of function/class _names_17:50
kanzurebut let's say i pick one function and want to twiddle with it a bit17:50
kanzurewtf. *MB17:51
QuantumGload the dll up in IDA.. copy out the asm, convert it to semantics by hand, do the minimum amount of work to get it into C, compile it, patch the DLL in memory to point to your new code (either use a debugger or inject a new DLL into the process) and test a lot to see if your C replaces the function correctly.. then try to make the function easier to read.17:53
kanzureyou're insane :)17:54
kanzurei've never done DLL patching though17:54
kanzureany hints or tutorials or links on that?17:54
QuantumGbut.. if you give me the DLL I'll take a look for ya17:54
kanzureno thanks, there's nothing in particular i want in it17:54
kanzureif you have some tools to do this automatically and clean up common crap, then sure17:55
kanzurehow do you swap out the addresses in the DLL file?17:55
QuantumGya, I don't.  You can try Boomerang ... but I stopped working on it a few years ago, so I don't know what state it is in17:55
QuantumGinsert a jump at the start of the original function to your replacement function17:56

kanzureby "fuck up" i mean change the size and thus fubar everything, all the offsets, etc17:57
QuantumGwell, you overwrite the original 5 bytes of code with the jump17:57
QuantumGso you're not inserting anything17:57
QuantumGway I typically do it is to write a DLL with a init function that patches the original DLL and inject it into the running process17:59
kanzurehow do you inject DLLs into a process?17:59
QuantumGhttp://quantumg.net/injectdll.php17:59
kanzureheh17:59
kanzuresource and everything :) thanks18:00
kanzurewhat's with the random comment spam?18:00
QuantumGno idea, people are dicks18:01
kanzurewonder if this works under wine18:01
QuantumGyou'll need to VirtualProtect the original code of the DLL that you want to overwrite, to make it writable18:02
wrldpc2is there a build of skdb I can point someone to?18:03
QuantumGanother way of getting your DLL into a process (and there are many) is to look at the imports of the main EXE and see if there are any DLLs that are imported with only a few imported functions18:06
QuantumG1 is best18:06
QuantumGthen you just write a wrapper for each function18:06
QuantumGname your DLL the same as the imported DLL (renaming the original DLL if needed) and shove it in the same dir as the EXE18:07

genehackerreally?19:17
genehackerso I want to draw lines to make a gear, I assume it's pretty simple to do such a thing/19:17
kanzurei suggest you do it the way fenn did it for you19:19
kanzurewith a python script to write svg19:19
kanzureand then import it into heekscad and convert to dxf19:19
genehackerok19:19

kanzurewhy are you.. why are you printing this shit otu?21:50
kanzure*out21:50
ybitbecause i don't have a notebook computer21:50
kanzureuh, want one?21:51
ybiti'm supposedly getting one in less than a week so that i can have one while traveling21:51
ybitif that weren't the case, then yes21:52
kanzurei'll give you one if you buy a $40 power adapter for it. 21" screen. P4 dual core (yes it's old)21:52
ybit21" o.O21:52
ybitthat's bigger than my desktop screen21:52
ybitthat's probably still faster than this computer21:53
kanzureit's what i was using all through high school21:53

ybiti've done some stalking awhile ago, so you don't have to21:55
ybitright so if he needs a place, we can fit a roll-away in is what i was told, they doubled checked for me21:55
ybitit's $20 extra per night21:55

kanzureactivation/registration22:00

fennQuantumG: electrorheological fluids work on voltage, not current22:00
kanzureyeah it's a pain in the ass, ybit22:00
QuantumGexample: I had a game that would switch out of full screen every time my mouse moved off the screen with synergy.. I figured out how it worked and why it was doing that.. so rather than patch the binary I just wrote a dll that patched it in memory22:01

genehackerarmor?22:04
fennwell in that case you probably want magnetorheological fluid22:05
fennit works a lot better, no high voltages etc22:05
