Time Nick Message
00:01 [scs] rgs__: mmm..
00:01 rgs__: creo que ahora funciona todo, en realidad
00:03 rgs__: lo que no sé es dónde poner aquella función que me diste, function irc(){ screen -D -R;}
00:05 rgs__: porque en el caso de zatoichi vi que el .bashrc está linkeado a otra parte... supongo que podría mandar a la mierda el link y hacer mi propio .bashrc
00:07 rgs__ [scs]: aver
00:07 [scs]: .bashrc.local
00:08 [scs]: LibreOffice es la suite de oficina que te mostro EG?
00:10 [cronos] rgs__: Symphony, es de IBM
00:11 rgs__: entre paréntesis ya se comenzó el programa de software libre en Itaipú
00:12 rgs__: estoy con algunos informáticos de Itaipú en un curso de gestión de proyectos y son algo linuxeros los tipos
00:13 rgs__: creo que por el tema de la particularidad de la tecnología de usina, y su contacto con brasileros, son algo avanzados
00:13 rgs__ [cronos]: vi lo de itaipu + SL
00:14 crodas: fantastico
00:14 [cronos]: ^
00:14 [cronos] rgs__: hablame nomás a [scs], le puse hilight también desde acá
00:14 rgs__ [scs]: ok
00:14 -> dormir
00:15 [cronos] rgs__: que descanses profesor, mañana es feriado acá, así que hoy salimos con Bacco

15:10 rgs__ morganya: hi ho
15:11 morganya: we have a long awaited conversation pending :)
15:13 morganya rgs__: hi! yes, sorry. The hotel internet went out on Monday so I wasn't able to chat then.
15:15 (seemed to happen a lot in Peru!)
15:17 rgs__ morganya: np, so you would be kind enough to set us both on context of what was pending of discussion?
15:19 morganya rgs__: sure. :) I've been doing a bit of number-crunching on the Inventario data and would be happy to do the same for the server logs, if there's a way to scrape them ... you were saying they were pretty incomplete in some ways (the XO doesn't log a lot of data) but I think they could still be interesting.
15:19 rgs__ morganya: server logs == journal backups ?
15:20 morganya rgs__, bernie: for the Inventario data, Bernie was suspecting that there were more boys breaking laptops than girls ... if you divide it out by breakage type, all the numbers are pretty close except for screen breakages, interestingly.
15:20 rgs__ morganya: what type of questions are we trying to answer? Or what type of data (or activities) are we looking for?
15:20 morganya rgs__: ah, sorry -- server logs = journal backups and/or internet downloads
15:20 rgs__ morganya: well.. it follows conventional wisdom.. girls are much more caring than boys!
15:21 morganya: internet usage patterns are kind of easy cause we have the (Squid) proxy logs
15:21 morganya though it isn't nearly as bad as Bernie suspected. :)
15:22 for the journal backups, it depends on exactly what data is there, but frequency of use of different activities during/after school would be one good one that has been hard to get from self-reports.
15:22 rgs__ morganya: journal backups provide some meta info but it ain't as rich as it could be... once I did some analysis on what activities were used the most but my method for calculating this was very naive
15:22 morganya (of course, plenty of kids erase their journal, but it's still something ...)
15:23 rgs__ morganya: let me see if I get the question you are trying to answer.. which activities are used during school time vs home time?
15:24 morganya for the internet patterns, one ofmy overarching goals is to deconstruct "games" -- in academic and journalistic circles, "games" has come to be a proxy for "time-wasting," but as part of this work I would really like to enrich this definition by analyzing different types of games. Internet may not seem like a good proxy for this but when so many games are downloaded ...
15:25 I have qualitative data on use patterns but I would like to triangulate with some quant data on what games get downloaded and what sites are most popular.
15:26 for the internet logs, I'm also interested in what sites overall are most popular -- a kind of pop-culture analysis into students' use.
15:26 rgs__ morganya: we've got abundant logs to do that type of number crunching
15:26 morganya: so, lets wrap up a plan for the internet usage analysis and lets move to Journal analysis afterwards, sounds good?
15:26 morganya for the journals, yeah, what activities are used in school time vs. home time is a good way to put it. :) I may have others -- often with a dataset I kind of play around making different graphs and seeing what data I can extract from it and generate new questions that way ...
15:27 sure!
15:27 rgs__ morganya: yikes, I am speaking with the next Malcom Gladwell!
15:27 :p
15:27 morganya (my ideas for the journals are more vague anyway because I'm less sure about what info is there ...)
15:27 rgs__ hopes Morgan likes Malcom G. and takes it as a compliment
15:27 morganya ha, I wish! :)
15:27 yes, very much :)
15:27 rgs__ morganya: so, no rocket science for the internet logs:
15:28 morganya: you need
15:28 1) permission from pyedu to access them (trivial)
15:28 2) with a bunch [B2) with a few lines of Ruby/Python
15:28 we'll be able to toss the data into a DB and run a few queries
15:29 and then you'll have to do some hand classification
15:29 morganya rgs__: yeah
15:29 rgs__ (i.e.: this set of URLs are math games, etc.)
15:29 morganya: sounds correct? Am I missing something?
15:29 morganya rgs__: that sounds about right!
15:29 rgs__ morganya: [scs] should be able to answer #1
15:29 [scs]: ^
15:30 morganya: I suspect they'll want there name on your Pulitzer-winning reports
15:30 morganya ha, of course :)
15:30 rgs__ *their
15:30 morganya: I still have access to school servers, so once we've got [scs]' blessing we can start parsing & crunching the logs
15:31 [scs]: ^
15:31 morganya I should send you some of the breakage graphs, if you're interested, too ... I'm hoping to draw up a document that PyEduca would be interested in publishing about it.
15:31 rgs__: awesome. :) thank you for your help.
15:31 rgs__ morganya: and that wont get OLPC pissed off (again) !
15:31 morganya yeah :(
15:31 rgs__ morganya: haven't done anything yet, but you are welcome
15:31 morganya I certainly hope not!!!
15:32 (not my intention at all, anyway ;))
15:32 rgs__ morganya: so I'll let you reach scs and wake him up from his crazy party of yesterday
15:32 morganya haha :)
15:32 rgs__ morganya: in parallel we can discuss the Journal
15:32 morganya I'll chat with him later today
15:32 (since it's a holiday, I'm actually typing from bed :P)
15:32 rgs__ morganya: so, about the anatomy of Journal entries
15:33 morganya: (happy you - I am working hard from Trento's University visitor's office :p )
15:33 morganya hehe
15:33 rgs__ morganya: each entry has a metadata file associated
15:33 morganya: which is basically a hash serialized in JSON format (that is, trivially parseable since JSON just rocks and its the best serialization format ever)
15:33 bernie: ^
15:34 morganya: let me fetch an entry so we can disect each key/value pair
15:34 morganya ok
15:35 rgs__ morganya: we've got the following fields (all of them, mostly, self-descriptive):
15:35 activity activity_id buddies checksum description icon-color keep mime_type mtime preview progress timestamp title title_set_by_user uid
15:35 morganya: things that those values tell us:
15:35 1) what (activity)
15:36 2) when
15:36 morganya ooh! sharing data would be *fascinating* too!
15:36 (if that's what buddies is)
15:36 rgs__ 3) who (used alone or collaborating with others)
15:36 4) did he set a title or he didn't
15:36 5) ...
15:36 morganya: (yup - that is what buddies is AFAIK)
15:36 morganya what is progress?
15:36 rgs__ morganya: I suspect its a field use for downloaded stuff
15:37 morganya keep = whether it was saved?
15:37 ah yes
15:37 and timestamp would be the last time it was touched? or last saved? or created?
15:38 ah, there's timestamp and mtime
15:39 so mtime is probably last modified, and timestamp is one of the other two (maybe = ctime)
15:40 rgs__ morganya: thinks so (keep == saved)
15:40 morganya: sorry - gotta run . can we resume this later? :( (sorry sorry)
15:40 morganya sure!
15:40 this was already very helpful. thanks!

19:00 rgs__ morganya: i am back
19:01 morganya rgs__: hi!
19:02 [scs] is sitting nearby at Carla's house, reading, Marx&Engels
19:04 op, actually, it's Weber
19:11 rgs__ morganya: Weber is cool, although I know him superficially
19:11 morganya: great activity for a Holiday though
19:11 morganya: I am planning on getting Noam Chomsky's latest book (Hopes and Prospects)
19:11 morganya: sigh.. got to get a shower now because there is a party I have to join from the students here in the dorm of the University of Trento
19:12 morganya rgs__: I haven't seen that one yet myself!
19:12 rgs__ morganya: so.. can you drop me a line (rgs AT rieder.net.py) with questions about the fields on the metada of Journal entries?
19:12 morganya: and how/what you'd like to deduce of them
19:12 morganya: I work much better asyncronously (via email) :p
19:12 morganya: and sorry for so much latency in our conversations
19:15 morganya rgs__: no problem! I often work better that way myself. Easier to remind myself of the context of a conversation. :)
19:17 rgs__ morganya: nice! I'll wait for your lines then
