kanzureyashgaroth: so how is jcline doing? i haven't seen him since 200912:36
yashgarothhe's got his own openpcr project going, no comment there12:36
yashgarothhe brought up your dna synth project and I was all 'yes I'm familiar with it'12:37
yashgarothseems to be in an RNAi phase but I'm sure it'll pass12:37
kanzurehe had a microfluidics project a few years back12:37
kanzurehe was doing electrowetting on dielectrics to move droplets around in open atmosphere12:38
yashgarothseemed interested in helping with the open spec project too12:38
kanzurelast i heard he was working for some lab automation startup in san diego?12:40
yashgarothprobably, I'd no idea who he was at the time so it was just general bullshitting...but yes I think he mentioned something about robits12:42
kanzureyeah sorry about forgetting to introduce you to him12:42
yashgarothquite alright; I don't think he'll be at the thing today, but I'm sure we'll encounter each other at the space12:44
kanzurehe used to hang out in here12:44

fennkinda wish he had implemented the recommendation engine. "buy me random crap" isn't even art, just .. defeatist.14:18

fennhuh i wonder if you can buy your own debt http://rollingjubilee.org/#faq15:08
drethelin1I think viewing education as a basic neccesity is one of the worst failings in america15:10
drethelin1also it looks like you can't buy any specific person's debt15:11
fennyeah nobody is "forced into" college15:12
fennbut still, lots of young people are pressured into it, not knowing what they're getting into, essentially being lied to by institutions they're expected to trust15:12
drethelin1they're not exactly lies15:12
drethelin1because the institutions are also fooled15:13
fennthe banks know exactly what they're doing15:13
doclyou sure the pressure to get people educated is a bug not a feature?15:13
drethelin1the very idea that spending tens of thousands of dollars to get a english degree is useful is getting both sides15:13
drethelin1the issue isn't "education" in general15:13
fennwhen they tell you to get a private loan instead of a federal loan, that's in the banks best interest but fucks you over15:13
drethelin1education is the applause light version of what's actually happening15:13
drethelin1you can't argue against "education" just like it's hard to argue against "freedom"15:13
drethelin1but the 4 year college system in the USA is a parody of learning15:14
doclyou're saying that useful education and useless education are being conflated?15:14
docle.g. STEM vs lit15:14
fenni agree, but additionally there are predatory financial practices surrounding the educational system15:14
drethelin1docl, yes15:14
drethelin1also: education is being treated as something with intrinsic value15:15
doclisn't it?15:15
drethelin1it's value is a function of the person and the other choices they make15:15
fenn"intrinsic value" is shaky philosophy15:15
fennhow much is gold worth15:15
drethelin1many (possibly most) people don't need a college degree to live a happy life doing what they want15:15
doclthe point of education is not so much the betterment of the individual (imho) but the spillover benefits for society.15:16
drethelin1docl, that's a reasonable argument for public education in general but not for education as she is played15:16
drethelin1eg there's no good evidence that society is made better off by a bunch of people spending 4 years getting drunk and getting a useless degree15:18
drethelin1or even by learning most of the stuff that is taught in high school15:18
docldepends how they would have spent the 4 years otherwise15:18
drethelin1current curriculums are far more an artifact of what the past thought was high status than what you would create in a vacuum to generate good citizens15:18
drethelin1consider all the mandatory classes you have to take in college to become a "well rounded individual'15:18
* fenn grumbles something about montessori education15:19
doclso, bloatware essentially15:21
drethelin1yeah I guess15:21
doclstuff that gets added, has to be kept for backwards compatibility and so forth, but you would never dream of adding it to a new system if you knew what you were doing.15:23
drethelin1it's worse than that because stuff that got added 100 years ago eventually comes to be valued as a tradition etc.15:24
drethelin1ie, people don't even admit that it's bad15:24
docllike football?15:24
drethelin1football is a good example15:24
fennmarching band15:24
drethelin1Marching band is at least not actively terrible15:24
kanzurei am confused, what are you arguing about15:24
drethelin1we're not15:25
drethelin1we're agreeing15:25
drethelin1which is a bad sign15:25
fennabstinence class? what's actively terrible?15:25
drethelin1there's costs and there's opportunity costs15:25
drethelin1football causes brain injuries etc. as costs15:25
drethelin1marching band doesn't seem to impose costs like that on participants15:25
fennwell, it's one of the more pointless things i've ever done15:26
doclperhaps these things are natural tradeoffs for institutionality, which is in turn beneficial by resolving group coordination problems.15:26
doclcan't just think one dimension on this stuff.15:27
fenni'm interested in your ideas on what "should" be included in an educational curriculum15:27
drethelin1I agree that institutions are valuable for that sort of effect but the problem comes when they calcify out of date values15:27
kanzureis there any actual useful post-grad level courses on opencourseware yet?15:27
fennthe electronics class looked okay15:28
fenni decided the format wasn't for me15:28
-!- rainfrog [~swamp@p5B16EC63.dip.t-dialin.net] has quit [Quit: interacting processing]15:28
kanzurei am just tired of all the intro classes15:28
drethelin1Fenn, depends on if we're talking the equivalent of high school/elementary or if we're talking about college stuff15:28
kanzureyou really only need one "intro to philosoethics" class really15:28
fennintro is a good start15:28
drethelin1I think college stuff is a lot closer to good and would be fine if it wasn't functionally mandatory15:29
kanzurebut why isn't there 900 level optics class on the list15:29
kanzureor, you know, the useful things15:29
drethelin1kanzure, there are a lot more amateurs than knowledgeable people15:29
fennwell, the intro electronics class was actually quite advanced15:29
drethelin1and they need ad revenue15:29
drethelin1or whatever15:29
kanzuredrethelin1: just because i am amateur doesn't mean i don't want all of the classes. fuck off.15:29
fennhttp://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-002-circuits-and-electronics-spring-2007/15:30
kanzureyeah i know about 6.00215:30
drethelin1presumably the worth of uploading any given class is a function of how much effort it takes versus how many people will then use it15:30
drethelin1so if the effort is the same for all kinds of classes the ones with fewer targets will be less uploaded15:30
kanzuredrethelin1: it is practically no effort for me to type transcripts, but for some reason i seem to be the only one that does it15:30
kanzurehttp://diyhpl.us/wiki/transcripts/15:30
kanzurei think everyone else is just an asshole or something15:30
fennalso there are 900 level optics classes http://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-977-ultrafast-optics-spring-2005/15:31
kanzurefenn: most of the content is just psets which is basically useless15:31
kanzureoh i see, lecture notes15:31
fennit's not video lectures?15:31
drethelin1clearly you should go ghost classes15:31
drethelin1and upload transcripts15:31
fennyou have to sign up to take the class to see the content15:31
kanzurebtw optics was just a random example i picked, but it looks like the content is thorough http://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-977-ultrafast-optics-spring-2005/lecture-notes/chapter1.pdf15:31
kanzureyou mean there's videos for this one? i only see lecture noets15:32
kanzurenotes15:32
fenni dont know15:32
fennjust notes would be confusing without context15:32
kanzurewell, notes seem to be more common than videos on ocw15:32
fennthe linked notes looks pretty standalone complete though, practically a textbook15:32
fennalso OCW doesnt need ad revenue15:35
fennit's barely any cost at all to put the course notes up online15:35
fennsince the class is being taught anyway15:36
drethelin1Sure but that's been true for years15:36
drethelin1and it hasn't been happening15:36
fennall OCW does is present a whole curriculum in a standardized format15:36
drethelin1so there must be something that prevents people from doing it15:36
fennit's just a coordination problem15:36
docllots of professors put their notes and lectures online.15:36
fennprofessors have been uploading course notes since the bbs days15:36
fennand copyfight prevents people from aggregating them15:37
docland darknet doesn't care enough?15:38
kanzurewe are the darknet15:38
docloh yeah15:39
fennno, nobody gets "mad propz" for uploading publically available educational content15:39
fennor whatever the motivation of warez groups is15:39
doclbtw found a nice free calculus text: http://www.math.wisc.edu/~keisler/calc.html15:41
fennbleh. how about "how to use mathematica" 10115:41
doclsee the reaction I get? :P15:42
fenncalculus has a reputation that goes far beyond its usefulness15:42
doclhttp://www.indiana.edu/~statmath/math/mma/gettingstarted/printable.pdf maybe15:43
fennwhy are you linking to random math textbooks now?15:43
fennoh i guess i should read the title :P15:44
fennsigh.. /me adds "learn mathematica" to the todo list, right under "learn emacs again"15:45
doclthe calc book starts with the concept of infinitesimals rather than limits. apparently calculus books have been doing it in the wrong order for hundreds of years.15:45
fennalex graveley was trying to come up with a dependency tree for educational content15:46
fennhe basically took the lazy way out and just scraped wikipedia categories15:47

fennchocolate isn't really a substitute for piracetam, is it16:00
fenni do need a good todo list solution though, preferably something ncurses based that is also a calendar and saves in a text based format16:01
fenni've been using calcurse but it has some dumb design decisions. perhaps i could fix it; it is just python after all16:02
kanzureorg-mode, yadda yadda16:02
kanzurehnb used to be nice until it wasn't16:02
fennbut org mode isnt a calendar?16:02
fenntbh i havent read a lot about it16:02
fennthere are a lot of asterisks16:03
fennoh there is a calendar view mode16:03
kanzurei'm pretty sure it's just a cleverly disguised "everything and the kitchen sink" thing16:04

fennby the "vim does that too" corollary16:07
fennwhy should it care about tabs?16:07
kanzureit just means that he writes with tabs (and it's hard to tell on github's html display that they are tabs and not whitespace)16:08
fennmeh16:08
fennas long as i dont have to use tabs i don't care16:08

upgrayedddhey, does anyone mind fetching me this paper from ACM as paperbot is down? http://dl.acm.org/citation.cfm?id=2384723&dl=ACM&coll=DL16:11

delinquentmekanzure, thoughts on instantiating an R script from within ruby vrs js?16:15
delinquentmeor fenn16:15
fenneh? it's just a system call, either way16:17
fennwhichever is most convenient16:17
upgrayedddthere might already be a library out there that makes it easy, like pgfSweave for R scripts in LaTeX16:21

kanzurefenn: wrong.. system calls are generally a bad idea if you're doing web applications like delinquentme is ostensibly working on17:10
kanzurefenn: what he should really do is make a task queue and then build a worker that consumes from the queue in whatever language17:10
kanzurehowever, calling r from latex sounds hilarious17:10
delinquentmeexcept the front end application is instantly using feedback from the R script17:11
delinquentmeacademia likes to look at everything on a computer as homogenous :D17:11
kanzurei would still highly recommend a queue and workers even if the results are streamed in through websockets to the page17:12
kanzureyou would just make these particular tasks very high priority17:12
kanzurethe important thing is to decouple them from page rendering or responding to other http things17:12
delinquentmeso the process is like this: click on google map, draw square via google map api, return lat + longitudes ... send lat + lng to R script to plow through 1 gig of data ... return array of biomes17:13
kanzureyeah that should be completely decoupled from an http request17:14
kanzureyour js should poll an endpoint to ask if it's ready yet17:14
kanzureand that endpoint will wait for the task to finish17:14
kanzurewhen the task is done it should update the db and tell itself where the results are stored17:14
kanzureif the plowing takes a really really long time, then you might also consider sending an email reminder when it's ready17:14
delinquentme=p17:15
delinquentmewere hoping it takes less than 1 second17:15
delinquentmeawesome right?17:15

kanzurewe have a cs.yale.edu person in here? huh17:16
fennoh just make a task queue and build a worker.. right..17:18
kanzuresarcasm?17:19
fennto call a script? i must be missing some context i guess17:19
kanzurewell let's say that his service is using a single http server17:19
kanzureand there's two users17:19
kanzuresuddenly this doubles the memory the http server is using for this mapping operation17:19
kanzureand the server is for http stuff, not number crunching17:19
kanzureso already things sound a bit weird, right?17:20
fennhe should have mentioned the "plow through 1 gig of data" part in the initial question17:21
delinquentmeyeah theres a bit of data17:21
delinquentmeand kanz is right thats a shit load of weight on a server ... especially once we're talking a number of users17:21
kanzurewell, you missed the context a few months ago when he took on an awful rails job17:21
fennsounds like a good educational experience17:22
kanzureso i sorta assumed it was some web application doing things it shouldn't17:22
delinquentmehaha17:22
delinquentmeyeah17:22
delinquentme@ fenn17:22
delinquentmenot you kan!17:22
kanzureit's okay i know you hate me / don't listen to me17:22
delinquentmei mean applications are supposed to do what we want :D17:23
fennanyway i think kanzure's advice makes sense17:23
delinquentmeso maybe an API call to a dedicated crunchy server17:23
kanzuredelinquentme: no17:23
kanzurei mean, that's better than your first solution17:23
kanzurebut let's say you want to use more than one cruncy server17:23
kanzure*crunchy17:23
kanzureand what if you have more than one type of crunching in the future?17:23
fennis delinquentme using heroku? i'm not really versed in how task queues work in general17:24
delinquentmefenn, nah its gonna be EC217:24
kanzurefenn: task queues are very easy to setup17:24
delinquentmewe run crazy shit so ... yeah17:24
delinquentmeheroku wont like us17:24
delinquentmekanzure, tutorial?17:24
kanzuresince fenn likes python i would tell him to install celery and rabbitmq-server17:24
kanzuresudo apt-get install python-celery rabbitmq-server17:25
kanzurein rails-land it's a little less complicated because the queue and the messenger tend to be the same (redis/resque)17:25
kanzureheroku definitely supports both resque and celery17:26
kanzurefenn: http://docs.celeryproject.org/en/latest/userguide/workers.html17:27
fennwow broken phones are cheap cheap17:27
fenna heretofore untapped resource17:27
kanzurethink of all that.. erm. computing power.17:28
fennwell for $20 buy it now/shipped i'm sure i can come up with something to do with it17:29
fennsome of these are $10 but they dont say what's wrong with them17:30
fennapparently the $20 works but needs a battery (another $5)17:30
kanzuredelinquentme: other thing to consider is if crunchy server breaks down or stops performing well. ideally your queue system will account for this and kick workers in the ass.17:31
