| nmz787_i | hmm, someone is complaining about the wireless version, apparently it has a wire connecting the two earbuds and it annoyingly brushed his shirt collar | 10:18 |

| nmz787_i | strange that their images feature people NOT wearing the earbuds | 10:20 |
| kanzure | delinquentme: by asking a lawyer that you pay | 10:27 |
| nmz787_i | hmm, the BRL-CAD website could be a bit more easier to navigate... just found a model repository! http://more.brlcad.org/ | 10:36 |
| sandeep_ | how should one store a combination Ph electrode (sealed & KCl Gel filled) ? with the same KCl solution filled inside the electrode or with a Ph4 buffer or a mixture of both and in what proportion ? | 10:36 |
| nmz787_i | with... 9 models in total it seems? | 10:36 |
| kanzure | most of their military equipment models are top secret and off limits :/ | 10:37 |
| sandeep_ | i have read recommendation for all the three methods online . but which one should be the best ? | 10:37 |
| nmz787_i | sandeep_: "If you do not have electrode storage solution use pH 4 buffer solution. If you have neither electrode storage solution or pH 4 buffer solution you can use pH 7 buffer solution for a short time" | 10:37 |
| fenn | kanzure do you know what happened to the "national cad model repository" or whatever it was called | 10:37 |
| fenn | we had a copy at one point but i forget what happened to it | 10:38 |
| fenn | and then the site went down forever | 10:38 |
| kanzure | predis lost funding for it maybe | 10:38 |
| nmz787_i | sandeep_: ftp://ftp.pasco.com/training/kisd/PASCO%20Training%20Jan%2027%202014/General%20resources/pH%20storage%20solution%20recipe.pdf | 10:38 |
| kanzure | paredis? | 10:38 |
| fenn | i mean, is there still a copy in your possession | 10:39 |
| nmz787_i | that PDF was over-rated: "Add 1g potassium chloride (KCl) per 100mL pH 4 buffer solution. Serve in pH electrode storage bottles" | 10:39 |
| kanzure | oh, probably | 10:39 |
| sandeep_ | nmz787_i, i can order the electrolyte (3.3 M KCl in my case) , however i would like to understand what should be used and why ? | 10:39 |
| fenn | oh btw i downloaded the bitcointalk warc, on gnusha | 10:40 |
| kanzure | the >80 gigabyte archive? | 10:40 |
| nmz787_i | "or a 50:50 mixture of 4 M potassium chloride and pH 4 standard buffer" | 10:40 |
| nmz787_i | sandeep_: probably has to do with giving the glass the best condition for A) not degrading B) not clogging with precipitate | 10:40 |
| nmz787_i | where B) can also include preventing biofilm clogs | 10:41 |
| nmz787_i | probably | 10:41 |
| fenn | nmz787_i: i think the brlcad repository was a google summer of code project | 10:41 |
| nmz787_i | kanzure: you have 80GB of CAD models? | 10:41 |
| nmz787_i | kanzure: what format? | 10:41 |
| fenn | no, the bitcointalk archive is 80GB | 10:41 |
| nmz787_i | sandeep_: "KCl and pH 4 buffer provide good conditions for mold to grow. To prevent mold from growing in storage solutions, use up to 4% of sodium benzoate or azide in the reference fill and storage solutions" | 10:41 |
| fenn | the cad models were like 4GB | 10:41 |
| nmz787_i | sodium azide is great shit for preventing growth | 10:42 |
| fenn | also it's explosive yay! | 10:42 |
| fenn | and a severe poison yay! | 10:43 |
| nmz787_i | well that's why it keeps yer chems clean! | 10:43 |
| sandeep_ | nmz787_i, why not only KCl and Sodium benzoate ? what role is Ph4 solution playing here ? | 10:44 |
| kanzure | fenn: here's some step files of weapons https://github.com/maduce/defcad-repo | 10:47 |
| kanzure | https://raw.githubusercontent.com/maduce/defcad-repo/master/Firearms/Double_Barrel_Derringer-PaulNoiseLess/Renders/render2.jpg | 10:47 |
| kanzure | osnap that might actually be fucking data be careful | 10:47 |
| fenn | kanzure: i seriously dislike those guys | 10:47 |
| nmz787_i | sandeep_: the glass seems to work better at acidic pH | 10:48 |
| kanzure | well who else is giving you heaps of data | 10:48 |
| fenn | oh wait i thought that was "defense distributed" | 10:48 |
| nmz787_i | sandeep_: "Most electrodes used today are combination electrodes, that is they have a glass pH electrode and a reference electrode in one body. Glass electrodes perform best when stored in slightly acidic solutions, pH 4 buffer is a good choice. Reference electrodes perform best when stored in the same electrolyte that is immediately inside the reference junction, typically saturated KCl. An optimal storage solution for | 10:49 |
| nmz787_i | combination electrodes is pH 4 buffer (clear not pink) with 225 grams of KCl per liter. Table salt, NaCl, can be used if KCl is not readily available. Distilled or deionized water should never be used as a storage solution unless you like buying new pH electrodes." | 10:49 |
| nmz787_i | "Should my lab electrode be a sealed or refillable electrode? When properly used neither design is inherently more accurate than the other. Sealed electrodes are convenient and suitable for most applications. Refillable electrodes allow the user to fill the reference cell with the solution of their choice, possibly improving the performance compared to a standard KCl electrolyte. The reference electrolyte in the refillable design | 10:50 |
| nmz787_i | can be recharged when it becomes depleted extending the electrodes life. It is a question of convenience vs versatility" | 10:50 |
| nmz787_i | that repo sucks though because it is 'compiled' right? being STL files inside | 10:51 |
| fenn | kanzure some of these things i'm not even sure how it works https://github.com/maduce/defcad-repo/blob/master/Firearms/22_Electric_v5-Proteus/Renders/render3.png | 10:51 |
| nmz787_i | oh I guess some are igs files, which is source right? | 10:52 |
| kanzure | jrayhawk is our resident weapons person, he will arrange a demonstration | 10:52 |
| fenn | it looks like a terrible chunky handgrip and a 1 inch plastic barrel | 10:52 |
| kanzure | step files are sort of like source depending on how pleasant the developers of that particular step exporter were.... sometimes they will just dump stuff into bags of triangles rather than cleanly-designed parametric geometrical part stuff.... | 10:52 |
| fenn | step is not source because no cad program uses it as the native format | 10:53 |
| fenn | it's literally an exchange format | 10:53 |
| sandeep_ | nmz787_i, " combination electrodes is pH 4 buffer" no its not , it is a combination of two chambers one filled with KCl and other with a Ph 7 buffer (+ a little kCl) | 10:54 |
| kanzure | oh right, you can't represent boolean intersactions other than actually performing those intersections before serializing to step | 10:54 |
| kanzure | yes, sorry | 10:54 |
| nmz787_i | https://dl.dropboxusercontent.com/u/32346798/OpenSourceCad.pdf | 10:55 |
| fenn | a wild pdf appeared! | 10:55 |
| kanzure | nmz787: i know you're on a quest for working open source cad and basically you will not find anything | 10:55 |
| nmz787_i | sandeep_: the two-parts are not exposed to the outside world though I think, one may be inside the other... so you only have 1 choice for storage | 10:56 |
| kanzure | nmz787: i'm sorry that i have not completely written an open source cad kernel with nurbs and parametric awesomeness but it's really hard and lolcad is only partially complete | 10:56 |
| nmz787_i | sandeep_: even if two distinct membranes were exposed... how would you partition the buffer so the correct storage buffer was only on the correct side of the electrode | 10:56 |
| kanzure | verbnurbs is so far the best implementation i have seen, even though it's a pile of javascript | 10:56 |
| sandeep_ | nmz787_i, exactly , that is my question | 10:57 |
| kanzure | and cadquery the best api | 10:57 |

| sandeep_ | nmz787_i, that is the reason i wanted to know what one should use Kcl , Ph4 buffer or a mix of both | 10:58 |
| * nmz787_i turtle graphics for CAD 2015! | 10:58 | |
| nmz787_i | sandeep_: those links and quotes all had the answer to that | 10:58 |
| nmz787_i | they all said a mix, along with some biocide | 10:58 |
| nmz787_i | if you have it | 10:58 |
| nmz787_i | and care about your electrode | 10:59 |
| sandeep_ | nmz787_i, mix in what proportion ? different sources mention different things | 10:59 |
| nmz787_i | so find the commonality | 11:00 |
| nmz787_i | they were all pretty similar | 11:00 |
| sandeep_ | this one is from vernier "Store the electrode in a buffer pH-4/KCl | 11:02 |
| sandeep_ | storage solution in the storage bottle. The pH Electrode is shipped in this solution. | 11:02 |
| sandeep_ | Vernier sells 500 mL bottles of replacemen | 11:02 |
| sandeep_ | t pH Storage Solution (order code PH- | 11:02 |
| sandeep_ | SS), or you can prepare additional storage solution by adding 10 g of solid potassium | 11:02 |
| nmz787_i | sandeep_: any differences are likely because of availability of reagents, or specific type of electrode... if you don't know if your electrode is special, it probably is what most other people commonly use | 11:02 |
| sandeep_ | chloride (KCl) to 100 mL of buffer pH-4 solution. " | 11:02 |
| sandeep_ | nmz787_i, the electrode is gel filled and its pretty common and dirt cheap as compared to other types except that every one has their own story for storing the electrode | 11:03 |
| nmz787_i | they all work on the same general principal though | 11:04 |
| nmz787_i | so they will share a lot of similarities | 11:05 |
| nmz787_i | I wonder if ion-torrent proton-transistor tech will ever make it to common pH meters | 11:05 |

| kanzure | juri_: you should remove the "escad" stuff, it tricked nmz787 into not doing haskell things | 11:48 |
| kanzure | if anything the "escad" stuff should be a separate library | 11:48 |
| kanzure | kragen: freecad's python api is okayish i guess, but really if you want a wrapper around opencascade you should just use pythonocc for now | 11:48 |
| juri_ | it's the primary interface, from how u use it. that said, i'm engaged in a dialog with several reprappers about changing the language. | 11:49 |
| juri_ | s/u/I/ | 11:49 |
| kanzure | kragen: the problem with opencascade is that it's a few million lines of poorly tested source code from the 80s written in russian, french and sometimes english, with variable names like "aMPBLPB" and "aMPBLI" | 11:50 |
| kanzure | juri_: that's so stupid. look, cad does not require the invention of a new language. | 11:50 |
| juri_ | kanzure: i'm needing a way to express constraints. | 11:51 |
| kanzure | steal everything from brlcad's constraint solving engine | 11:51 |
| kanzure | and from gecode | 11:51 |
| kanzure | (gecode is not gcode) | 11:51 |
| kanzure | by steal i mean "use that as a dependency" | 11:52 |
| kanzure | and not "reinvent the wheel" | 11:52 |
| kragen | every program is the invention of a new language | 11:53 |
| kragen | or several | 11:53 |
| juri_ | it's still a long term problem, at the moment, i'm just fixing bugs. | 11:53 |
| kanzure | kragen: please, what's wrong with just providing a library and providing bindings into whatever languages | 11:53 |
| kanzure | kragen: cad is a hard enough problem, you don't need to couple it into language design problems as well | 11:53 |
| kragen | you probably haven't seen the peter deutssch talk on this | 11:54 |
| kragen | which was a pretty challenging conceptualization when I first saw it | 11:55 |
| kragen | but it's grown on me | 11:55 |
| kanzure | "lots of language design" is not going to help you construct a nurbs intersection algorithm, you reach that point pretty quickly with basically any available programming language | 11:55 |
| kanzure | if you want to make languages, fine, go do it, but don't lie to me and tell me you're writing surface intersection algorithms | 11:55 |
| kanzure | and don't lie to your users | 11:56 |
| kragen | a program is a language whose sentences are the valid runtime states of memory, and whose semantics are transformations between those states | 11:57 |
| kanzure | openscad's language does not actually help you implement a cad engine | 11:57 |
| kragen | I can't tell if you hadn't seen my last message when you wrote that or just didn't understand it | 11:58 |
| kanzure | so there's no other possible alternative whatsoever? haha | 11:59 |
| kragen | but it is probably sort of hopeless because it took me watching Peter Deutsch talk for most of an hour and then thinking about it for months to understand this point of view, and not only is he better at expressing himself than I am | 12:00 |
| juri_ | kragen: url? | 12:00 |
| kanzure | can you show me how openscad's shitty attempt at a language (for example, it didn't have variables or conditionals for a long time) helps with surface intersection algorihtms | 12:00 |
| kanzure | *algorithms | 12:00 |
| kanzure | as far as i know, nobody has even implemented cad in openscad's language, so you are totally full of shit and wasting my time | 12:01 |
| kragen | but he wasn't trying to confront a hostile audience, and he put a lot more time into it than I have | 12:01 |
| kragen | kanzure: if you are going to put effort into making yourself more ignorant I cannot stop you | 12:01 |
| kanzure | please, i've been reading the openscad mailing list and following their commits for a few years now | 12:01 |
| kanzure | i would not say i am ignorant on this topic | 12:01 |
| kragen | you have completely failed to understand what I am saying, and so you're going off on an irrelevant tangent | 12:02 |

| kanzure | "every program is the invention of a new language" is not the topic | 12:02 |
| kragen | juri_: I am trying to find it but this wa a few years sback | 12:02 |
| fenn | reminds me of the terrible pre-behaviorist theories of neuroscience | 12:03 |
| fenn | "everything is language!" | 12:03 |
| kanzure | fenn: i wonder if that argument would still be used if openscad, for whatever insane reason, also implemented a kernel | 12:05 |
| kanzure | i mean an operating system kernel | 12:05 |
| -!- shubhamgoyal [~shubhamgo@118.189.209.93] has joined ##hplusroadmap | 12:05 | |
| fenn | what argument | 12:05 |
| kragen | yeah, it turns out that "everything is langauge" works better for linguistic machines like computers than for neuroscience | 12:05 |
| kanzure | just because "everything is language" wont help you find those stolen battle station plans | 12:06 |
| fenn | kragen: it's a worthless model, it doesn't tell you anything you didn't already know | 12:06 |
| kragen | in a sense neither does mathematics | 12:06 |

| the8thbit|work | Hello. I'm trying to mess with openworm, and was directed here from #machinelearning. | 12:18 |
| delinquentme | pH = pKa + log_10( 0.025 / 0.0025 ) | 12:18 |
| delinquentme | / subtract pKa both sides | 12:18 |
| delinquentme | pH - pKa = log_10( 0.025 / 0.0025 ) | 12:18 |

| delinquentme | / divide by -1 | 12:18 |
| delinquentme | pka = ( log_10 ( a- / HA) -pH ) | 12:18 |
| delinquentme | where'd I go wrong nmz787_i1 | 12:18 |
| the8thbit|work | I have NEURON installed on my target machine, but without GUI tools or python. How do I import the openworm connectome? | 12:19 |
| the8thbit|work | My goal is to install openworm on an embedded device, use solar as the 'nose' input, and modified servos for motion | 12:19 |
| delinquentme | install them | 12:20 |
| delinquentme | or get permissions to install them. | 12:20 |
| Viper168 | have you considered the dangers of unleashing robot worms on society? | 12:21 |
| the8thbit|work | Viper168: Yes, in fact, the social dangers are my primary motivation. I'm a mad scientist | 12:21 |
| the8thbit|work | delinquentme: that is not helpful | 12:21 |
| Viper168 | pandora doesn;t go backin the box man | 12:22 |
| Viper168 | *back in | 12:22 |
| kanzure | Viper168: that's off topic | 12:22 |
| kanzure | the8thbit|work: try bugging archels, he might know | 12:22 |
| kanzure | archels: ping | 12:22 |
| Viper168 | the best things in life usually are | 12:22 |
| the8thbit|work | kanzure: honestly, questions about robot worm ethics seems more on topic for something called ##hplusroadmap than my original question | 12:23 |
| kanzure | bullshit | 12:23 |
| kanzure | NEURON is like 100x more on topic | 12:23 |
| delinquentme | the8thbit|work, kanz want to unleash pandoras box thats why offtopic | 12:23 |
| delinquentme | the8thbit|work, install it once on a VM | 12:23 |
| kanzure | the8thbit|work: here are things that are on-topic in here http://diyhpl.us/wiki/declaration | 12:23 |
| the8thbit|work | kanzure: fiiiiiiiiiine I'm on topic sheesh | 12:24 |
| the8thbit|work | delinquentme: Install neuron in a vm? Why? | 12:25 |
| delinquentme | or if the UI is web based enable access to the machine from outside | 12:25 |
| kanzure | i don't think delinquentme has actually used NEURON | 12:25 |
| delinquentme | you're not installing it locally for some reason | 12:25 |
| delinquentme | be that sanitization or whatever | 12:25 |
| delinquentme | install it once in sandbox ( VM ) | 12:26 |
| the8thbit|work | delinquentme: I'm not installing it locally because the target device does not have a c compiler | 12:26 |
| delinquentme | .... | 12:26 |
| the8thbit|work | so I need to cross compile it | 12:26 |
| kanzure | wait, NEURON is java? | 12:26 |
| kanzure | so you'll have to use jython haha | 12:26 |
| the8thbit|work | delinquentme: I'm not too worried about breaking things. I can always just wipe the file system and follow the docs I wrote to get it back to how it is now if I need to... though I dont understand how NEURON would cause me to need to do that | 12:27 |
| kanzure | anyway this is how you load things https://github.com/pgleeson/TestArea/blob/master/pythonnC/Ex6_LoadCells.py | 12:27 |
| the8thbit|work | kanzure: NEURON is C with an optional python module | 12:27 |
| kanzure | ah, neuroconstruct is java, though | 12:28 |
| kanzure | i see | 12:28 |
| the8thbit|work | Ahh, yeah | 12:28 |
| kanzure | the8thbit|work: you might have to wait a bit for archels | 12:28 |
| the8thbit|work | I dont really understand what neuroconstruct _is_ other than that its some kind of GUI tool for reading and manipulating neuroML files? | 12:28 |
| the8thbit|work | Something tells me I DONT need neuroconstruct on the target machine, though. Which would be a good thing to avoid. | 12:29 |
| kanzure | "what do you mean not all robots have the jvm?" | 12:30 |
| nmz787_i1 | the8thbit|work: have you seen this https://github.com/openworm/OpenWorm/wiki/Neuron-Simulation-Engine-Tutorial#running-a-simple-simulation | 12:33 |
| the8thbit|work | nmz787_i1: Thats basically a NEURON hello world. It doesn't load in openworm | 12:34 |
| nmz787_i1 | delinquentme: not sure, but ph and pka stuff is all over the nets, simple equations so I think you just need to debug a bit to get what you want. I also don't know what you want | 12:34 |
| nmz787_i1 | the8thbit|work: sorry I am just googling things | 12:35 |
| nmz787_i1 | the8thbit|work: I don't know the software at all | 12:36 |
| the8thbit|work | nmz787_il: you're good, I appreciate the effort :) | 12:36 |
| nmz787_i1 | found a ref to a lego robot using it here supposedly | 12:36 |

| nmz787_i1 | I guess they're talking about that or http://www.oreilly.com/biocoder/issues/BioCoderFall2014.pdf | 12:37 |
| the8thbit|work | yes it does work! | 12:37 |
| kanzure | openworm used to be on irc until they decided they preferred looking at their faces on google hangout | 12:37 |
| the8thbit|work | I'm not the first person to try to put a worm brain in a robot body tho :( | 12:37 |
| the8thbit|work | oh well, I can be the second | 12:38 |
| the8thbit|work | kanzure: well thats fucking stupid :( | 12:38 |
| the8thbit|work | irc > google | 12:38 |
| kanzure | have you used NEURON in the past? | 12:38 |
| nmz787_i1 | ahh the fall one | 12:39 |
| fenn | the8thbit|work: instead of cutting off the pig's feet why not just install debian on a small low-power ARM computer like for example any smartphone | 12:39 |
| the8thbit|work | fenn: the... pigs feet? | 12:39 |
| fenn | well, anything with java is a pig, obviously | 12:39 |
| nmz787_i1 | my farmer was pissed the butcher didn't return the feet | 12:39 |
| nmz787_i1 | oh, wait, that was the ears | 12:39 |
| nmz787_i1 | the8thbit|work: lego mindstorms is useful though... it was probably my first example of non-game programming that interested me | 12:40 |
| the8thbit|work | fenn: This device was given to me on loan from my workplace. The hardware, kernel variant, and OS ecosystem are all custom built internally. Part of the reason I'm doing this is to familiarize myself with their systems and to impress my boss so that he hopefully moves me into a cooler position | 12:40 |
| fenn | the8thbit|work: cnrun is a "NeuroML-capable neuronal network simulator" with minimal dependencies | 12:41 |
| the8thbit|work | fenn: Is that just an alternative to NEURON? | 12:42 |
| fenn | looks like NEURON is an entire package of tools as well as an API | 12:45 |
| kanzure | yes, it's also a gui | 12:45 |
| kanzure | and.... many other things. | 12:45 |
| nmz787_i1 | ordered a 128GB SSD last night for $63 shipped, 42mm long! (for a C720 chromebook) | 12:47 |
| bkero | Mmm, those | 12:47 |
| nmz787_i1 | when was the first USB flash drive released? | 12:47 |
| fenn | the8thbit|work: there are at least 3 domains you need to be familiar with, the software stack involved in NEURON, the software stack of your particular robot, and actual neuroscience (so you can understand what openworm is doing) | 12:48 |
| fenn | it's going to be easier to learn them separately than all at once | 12:48 |
| kanzure | he's just looking for the exact api call | 12:51 |
| kanzure | or file loading mechanism | 12:52 |
| the8thbit|work | ^ | 12:56 |
| kragen | nmz787_i1: maybe around the time of the Diamond Rio? | 12:56 |
| kragen | although it carefully did not function as a flash drive when it came to being able to read it, because of audio laws | 12:56 |
| the8thbit|work | fenn: I'm not looking to do anything fancy with neuron, just pull in the existing connectome for openworm | 12:56 |
| nmz787_i1 | I had a flash-drive based MP3 player that also functioned as a drive... I think I had a 128MB version | 13:01 |
| nmz787_i1 | that was in 2001 probably that I got it | 13:01 |
| nmz787_i1 | MuVo I think it was | 13:01 |
| the8thbit|work | nmz787: I think my first flash drive was 64mb | 13:02 |
| nmz787_i1 | yea Creative MuVo | 13:02 |
| nmz787_i1 | if not for cell phones, I would probably still prefer that to an iPod type | 13:02 |

| nmz787_i1 | PCMCIA seems like a bit of a waste, since it's only about half the size of a 1.44MB diskette... though PCI interface would increase speed performance | 13:11 |
| fenn | but it's random access so a zillion times faster for some tasks | 13:11 |
| fenn | also solid state so more reliable | 13:11 |

| nmz787_i1 | uh, it was part of the question | 13:16 |
| fenn | fine whatever | 13:16 |
| nmz787_i1 | I mean, I enjoy the further backstory | 13:16 |
| nmz787_i1 | I wonder if anyone ever developed or even just prototyped a diskette-based flash drive... like the 3.5mm to audio tape converters they sell for cars | 13:19 |

| kragen | PCMCIA and CompactFlash (same pinout, different form factor) are still somewhat alive | 13:23 |
| fenn | some PIC microcontrollers still use EPROM and must be "flashed" with UV to erase the memory | 13:24 |
| kragen | nmz787_i1: I understand that some current USB drives actually implement VFAT in software, which is pretty similar ((albeit at a different lecvel) to a diskette-based flassh drive | 13:24 |

| kragen | a diskette-based flash drive would suffer from those limitations and also the 1.44MB capacity limit | 13:26 |
| fenn | seems like one-time-programmable "vaporize a wire" type memories would last a long time, for archival purposes | 13:27 |
| nmz787_i1 | kragen: sure it could be limited to 1.44 MB, or have a microswitch on the edge to cycle through multiple disk images stored within | 13:28 |
| nmz787_i1 | I just think it would be cool | 13:28 |
| nmz787_i1 | not practical, unless you were dealing with legacy/old equipment | 13:28 |

Students can purchase a fully-featured edu license for under $140, so if you are still in the academia, it would be foolish not to go for it. For mere mortals, there is a heftier price tag attached - $750 - so it's a more difficult call. Still, it's a ... | 23:00 |
| nmz787 | ... mature and user-friendly tool that runs well even on low-end systems, and it's just done well - so you probably won't regret it." | 23:00 |
| nmz787 | "Now, if Rhino is priced outside your league, many people in the community are also fond of Alibre Design PE, which sells for about $100. Or, if you prefer not to spend any money at all, and can live with a somewhat clunky app, then FreeCAD looks fairly OK for simpler work." | 23:00 |
| nmz787 | "Last but not least, cash-strapped DIYers may also want to check out one of the "demo" editions of commercial CAD tools. For example, Creo Elements has a modest limit of 60 parts per document, but otherwise, should do the trick." | 23:01 |

| nmz787 | "McNeel Rhino 5.0 also supports polygon meshes and point clouds for a complete coverage of geometric data types. With its unparalleled modeling power McNeel Rhino 5.0 lets you focus on designing, not on cumbersome modeling workarounds." | 23:02 |
