| kanzure | papers, mostly | 16:49 |
| ybit | i didn't know there was an open-rtms list | 16:49 |
| kanzure | on the sourceforge mailing list for open-rtms there has been some recent discussion if you're interested | 16:49 |
| kanzure | oh :) | 16:49 |
| kanzure | http://open-rtms.sf.net/ | 16:49 |
| kanzure | something about needing to set up a line integral framework for getting the right coil designs | 16:49 |

| genehacker | why? | 19:09 |
| kanzure | would you like to? | 19:09 |
| genehacker | yes | 19:09 |
| genehacker | very much so | 19:09 |
| genehacker | why? | 19:09 |
| kanzure | http://superkuh.stumbleupon.com/ has the link on the front page | 19:09 |
| genehacker | ah yes superkuh | 19:10 |
| kanzure | hm? | 19:10 |
| kanzure | did I introduce you to him or tell you about him yet? | 19:11 |
| genehacker | you did | 19:11 |
| genehacker | I think I found his brain scan on youtube | 19:11 |
| kanzure | yep. | 19:12 |
| genehacker | now as you were saying | 19:12 |
| genehacker | you want to do some ECM? | 19:12 |
| kanzure | not right now | 19:13 |
| kanzure | I just saw the link and thought you'd like to know | 19:13 |
| genehacker | ok | 19:13 |
| genehacker | so I've been reading about the filter | 19:13 |
| genehacker | how it works and all | 19:13 |
| genehacker | it works by something called the tubular pinch effect | 19:14 |
| genehacker | particle flow in a pipe is interesting | 19:16 |
| kanzure | links please | 19:17 |
| genehacker | http://www.google.com/search?q=tubular+pinch+effect&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a | 19:17 |
| kanzure | well, no, what about the link to where you learned about tubular pinch effects? | 19:18 |
| genehacker | http://www.google.com/url?sa=t&source=web&ct=res&cd=7&url=http%3A%2F%2Flinkinghub.elsevier.com%2Fretrieve%2Fpii%2FS0021967307009776&ei=qQ19Sdn4EJGYsAPFu-Uu&usg=AFQjCNFUx54o10D-9GOq0Ar8iAUUD4xOfg&sig2=iZtR70kjGo09forZffUo6g | 19:18 |
| genehacker | it's really annoying though, some of the papers that explain the tubular pinch effect aren't free | 19:19 |
| kanzure | aren't you on the UT network? | 19:19 |
| genehacker | yeah | 19:19 |
| kanzure | if you find one that isn't free, just tell me | 19:19 |
| kanzure | it turns out that I can only access some of the content that UT can, | 19:20 |
| kanzure | but if I ssh into the mechanical engineering dept computers, | 19:20 |
| genehacker | heh | 19:20 |
| kanzure | I can get papers that are otherwise restricted | 19:20 |
| kanzure | which is retarded and dumb. but whatever. | 19:20 |
| genehacker | http://journals.cambridge.org/action/displayAbstract?fromPage=online&aid=387130 | 19:20 |
| kanzure | need it? | 19:20 |
| genehacker | yeah maybe | 19:20 |
| genehacker | I need the maths | 19:21 |
| kanzure | huh, that's a highly relevant paper | 19:21 |
| genehacker | that describe how the tubular pinch effect works | 19:21 |
| genehacker | so I can test this idea I have | 19:22 |
| genehacker | for a new filter design | 19:22 |
| kanzure3 | http://www.springerlink.com/content/g28838p5642g4312/fulltext.pdf | 19:22 |

| kanzure3 | desc: http://www.springerlink.com/content/g28838p5642g4312/ | 19:22 |

| kanzure | was it amputated? | 19:28 |
| nsh | state of being without credentials to an journal access proxy | 19:28 |
| kanzure | you know how to steal access, right? | 19:28 |
| nsh | enlighten | 19:29 |
| kanzure | there are ezproxy password trading rings on the warez forums | 19:29 |
| nsh | ah | 19:29 |
| kanzure | http://ezproxy.lib.utexas.edu/login?url=http://nature.com/ but you'd need a login/pass | 19:29 |
| * nsh nods | 19:29 | |
| kanzure | some computers are infected by keyloggers, so that information is sometimes captured and sent along to the warez folks. | 19:30 |
| nsh | i get the picture :-) | 19:30 |
| nsh | these warez forums you speak of... | 19:30 |
| genehacker | http://arxiv.org/abs/0811.1632 | 19:30 |
| genehacker | new paper is new | 19:30 |
| genehacker | heh, looks like we don't know how the tubular pinch effect works | 19:31 |
| kanzure | time for some simulations. | 19:31 |
| genehacker | of? | 19:32 |
| kanzure | of the effect? | 19:32 |
| kanzure | nsh: hm. | 19:32 |
| genehacker | that's why I want the math | 19:33 |
| kanzure | you should look for the experiments and then see what mathematical models they were using that 'almost worked' | 19:33 |
| kanzure | and then see how much they were off- it might have been by a delta, by an offset, etc.. | 19:34 |
| kanzure | nsh: http://heybryan.org/docs/ there's a txt file in here about that, warez_boards.txt maybe IIRC | 19:34 |
| nsh | thanks | 19:34 |
| kanzure | "Stupid shopping list.. turning food into work. Grr." - Homer. | 19:37 |
| genehacker | yeah | 19:37 |
| nsh | kanzure, check this too: http://forum.darkc0de.com/index.php?action=vthread&forum=6&topic=5455 | 19:38 |
| nsh | ( Posted: 31 Oct 2008 06:13 ) | 19:38 |
| nsh | i would script that list to check for 404's | 19:38 |
| nsh | weed them out | 19:38 |
| kanzure | whati s it? | 19:38 |
| nsh | actually, you could automate a spidering of warez boards... | 19:38 |
| kanzure | I'm not at my browser at the moment | 19:38 |
| kanzure | yeah | 19:38 |
| kanzure | yep, that's the idea | 19:38 |
| nsh | oh, big list of above | 19:38 |
| nsh | *of the above | 19:38 |
| kanzure | http://heybryan.org/projects/autoscholar/ might also benefit from an abstraction layer like that | 19:39 |
| nsh | what i'd do is run queries on random couplets from previous lists | 19:39 |
| nsh | to bring up results with other people's lists | 19:39 |
| nsh | then add them to the heap and re-prune via 404 checking | 19:39 |
| nsh | rinse lather repeat | 19:40 |
| kanzure | it's not quite as easy as 404, it's login invalid of course | 19:40 |
| kanzure | if HTTP 404 response was given that'd be awesome, but nobody ever keeps to the standard.. | 19:40 |
| nsh | sure, all the typical error codes | 19:40 |
| nsh | right | 19:40 |
| kanzure | bah, if people respected error codes :( | 19:40 |
| nsh | you can also fingerprint the sites to some degree each run | 19:40 |
| nsh | then make a simple metric for fingerprint identity on subsequent runs | 19:40 |
| kanzure | wget cna do the login, btw. | 19:40 |
| nsh | in case the domain gets turned into something crap | 19:40 |
| nsh | aye | 19:41 |
| kanzure | ezproxy is consistent across the sites, so it's not a big challenge or anything | 19:41 |
| kanzure | so they usually find out about an account being compromised, actually | 19:41 |
| kanzure | but that's probably because the usage behavior is all weird and such | 19:41 |
| kanzure | but | 19:41 |
| kanzure | if there's a way to hide this | 19:41 |
| kanzure | by properly load balancing each site | 19:41 |
| nsh | hmm | 19:41 |
| kanzure | then that might be worth investigating. | 19:42 |
| nsh | not sure what advantage you'd get over hit-and-run | 19:42 |
| nsh | but worth a look maybe | 19:42 |
| kanzure | many people hit-and-run == bad | 19:42 |
| nsh | true | 19:42 |
| kanzure | because then the account is locked down | 19:42 |
| nsh | depends on the frequency of new login captures | 19:42 |
| nsh | i tell you what though... | 19:42 |
| kanzure | I've never been able to figure out the real source of the new logins | 19:42 |
| nsh | a vulnerability in ezproxy would be the motherload | 19:42 |
| kanzure | it's always supplied by a few key individuals, but I also know that these people aren't running the botnets | 19:42 |
| kanzure | hm | 19:43 |
| kanzure | what server is it running on? | 19:43 |
| nsh | well, i meant the software in general on different institutions servers | 19:43 |
| nsh | though it's probably quite locked down | 19:43 |
| kanzure | yes, ezproxy is standardized | 19:43 |
| kanzure | some supplier got the big check :) | 19:43 |
| nsh | aye | 19:43 |
| nsh | hrmm | 19:44 |
| nsh | usually the usernames are quite formulaic | 19:44 |
| nsh | i wonder what could be done with dictionary attacks against usernames | 19:45 |

| kanzure3 | heh' | 20:19 |
| kanzure3 | I fail :( | 20:19 |
| nsh | i though i'd offended you with viscosity :-) | 20:19 |
| genehacker | I still don't get it | 20:20 |
| genehacker | how do I determine the renoyld's number of something | 20:20 |
| genehacker | or make sure that it is low | 20:20 |
| kanzure3 | http://esciencenews.com/articles/2009/01/25/rewrite.textbooks.transcription.bidirectional | 20:20 |
| kanzure3 | genehacker: you just need to make sure that (QD)/(vA) is low, where v = kinematic velocity (m^2/sec) | 20:21 |
| kanzure3 | A = cross-sectional area | 20:21 |
| kanzure3 | Q = volumetric flow rate (m^3/sec) | 20:21 |
| kanzure3 | D = diameter (m) | 20:21 |
| kanzure3 | uh, obviously, area = m^2 | 20:21 |
| kanzure3 | oops | 20:22 |
| kanzure3 | k = kinematic viscosity | 20:22 |
| kanzure3 | erm | 20:22 |
| kanzure3 | v = kinematic viscosity, http://en.wikipedia.org/wiki/Kinematic_viscosity | 20:22 |
| genehacker | what's cross sectional area in this case? | 20:22 |
| kanzure3 | dunno, what did you set it as in your model? | 20:22 |
| kanzure3 | in the CAD model | 20:22 |
| genehacker | why is it different than diameter? | 20:23 |
| kanzure3 | "generally include the fluid properties of density and viscosity, plus a velocity and a characteristic length or characteristic dimension. This dimension is a matter of convention - for example a radius or diameter are equally valid for spheres or circles, but one is chosen by convention. For flow in a pipe or a sphere moving in a fluid the diameter is generally used today. Other shapes (such as rectangular pipes or non-spherical objects) have an equivalent diameter defined. For fluids of variable density (e.g. compressible gases) or variable viscosity (non-Newtonian fluids) special rules apply. The velocity may also be a matter of convention in some circumstances, notably stirred vessels." | 20:24 |
| kanzure3 | "by convention" wtf type of answer is that | 20:25 |
| genehacker | I'll figure it out later | 20:25 |
| genehacker | it's homework time | 20:25 |

| ybit | Removing heybryan.org/~bbishop/docs/open-rtms/index.html?C=S;O=D since it should be rejected. | 22:25 |
| kanzure | since what? :p | 22:25 |
| ybit | wget -A pdf -r http://heybryan.org/~bbishop/docs/open-rtms/ | 22:26 |
| ybit | oooh | 22:26 |
| ybit | well | 22:26 |
| ybit | -r explains everything | 22:26 |
| ybit | no l1 | 22:27 |
| kanzure | wget -m -np | 22:27 |
| fenn | -r shouldnt repetitively get the same file over and over unless there's a cyclic symlink | 22:27 |
| fenn | for most situations i like wget -rk -np -nc | 22:27 |
| kanzure | nc? | 22:27 |
| kanzure | k? | 22:27 |
| fenn | -nc for interrupted downloads | 22:27 |
| fenn | -k converts links to work on a local copy (otherwise they point to the original site) | 22:28 |
| kanzure | ah right, I was complaining about that with my transhumantech mirror | 22:28 |
| fenn | you were trying to do something weird | 22:28 |
| kanzure | -m for mirroring :) | 22:28 |
| kanzure | well, yes, true | 22:28 |
| ybit | [22:22] <fenn> -r shouldnt repetitively get the same file over and over unless there's a cyclic symlink | 22:29 |
| ybit | huh | 22:29 |
| ybit | wonder why it was doing over and over then | 22:29 |
| kanzure | I think it's because index.html might link to itself or something .. | 22:29 |
| kanzure | erm, wait | 22:29 |
| kanzure | I mean, if index.html was not the .htaccess' index file. | 22:29 |
| kanzure | but that shouldn't be the case there.. | 22:29 |
| ybit | welp, gots to run. i'll figure it out in the morn. | 22:31 |
| ybit | and kanzure, i will read your never-ending response on the russian OS thread and get back with you | 22:32 |
| ybit | ..tomorrow | 22:32 |
| ybit | hold the fort down | 22:32 |
