12:27 (join) jonrafkind
12:27 Lajla: but it's a serious quaestion, nay?
12:27 eli: Sure it is.
12:27 Lajla: And terribly on-topic, if I do say so myself.
12:27 Lajla: So, why is it trolling?
12:27 eli: One that requires more than some IRC chat.
12:27 eli: One that I'm being paid to teach as part of a course.
12:28 eli: One that takes considerable verbal effort, which will make putting it into short irc sentences pretty hard.
12:28 eli: And finally -- one that could be fitting for #racket-lectures, or more generally #scheme-lectures, or more generally #cs-lectures -- if anyone is crazy enough to do something like that.
12:29 tauntaun is doing just such a crazy thing.
12:29 Lajla: Well, then I at maxed asked a quaestion that was too complicated
12:29 Lajla: not trolling.
12:29 (quit) Demosthenes: Ping timeout: 260 seconds

12:35 eli: Lajla: If you've given people a reasonable grasp of the idea on irc, then the question that you asked me is most definitely trolling.
12:36 eli: tauntaun: on *irc*?  That would be insane, IMO...
12:36 Lajla: eli, why? that I know how it works from some perspective doesn't mean that another one isn't helpful in some way to me.
12:37 bremner: eli: I'll double check my litany of complaints against the latest source and get back to you.
12:37 Lajla: I didn't mean to troll you in any way.
12:40 tauntaun: eli: no, I mean live (you know what I'm referring to.)
12:40 tauntaun: But it's still free of charge.
12:40 eli: bremner: (BTW, in case you missed it in the noise -- there was a comment/question there for you.)
12:40 eli goes back to grading
12:41 bremner: eli: right, my response was "uhh, I'll have to double check"
12:44 eli: Lajla: It means that you already had a good grasp of the subject when you asked the question, yet didn't say that.  Had I actually started to reply to you, I wouldn't have assumed that and therefore I'd waste a good amount of effort for no good reason.  Lucky for me, I could guess what was coming and have avoided the whole wastage.
12:44 eli: tauntaun: Well, my point was that doing that in *irc* would be insane.  In a face-to-face lecture things work out much better, of course.
12:45 eli: bremner: OK.  Just as a reminder, this doesn't include the stuff in tests (which you should be able to just drop).
12:45 bremner: eli: right, good reminder.
12:46 eli: It's probably best if we deal with that too, though it will be harder to do that.
12:46 bremner: yeah, time being precious and all.
12:46 eli: :)
12:48 tauntaun: eli, you must have a done of grading if you've been doing it for two days straight...
12:48 tauntaun: (done->ton)
12:48 eli: tauntaun: Not really, I'm just lazy about it.
12:49 tauntaun: ah...
12:49 eli: I grade too well for my own good, which I usually cover up for by getting help; but this semester my grader seems overwhelmed.
12:49 eli: "too well" = write comments etc that I know most people will not read...
12:49 (quit) sethalves: *.net *.split
12:49 tauntaun: I imagine the test-taker would care about the comments, no?
12:49 tauntaun: (I know my students do.)
12:50 eli: I've been surprised in the past...
12:50 tauntaun: What are you teaching this semester? Same thing as last semester?
12:50 tauntaun: (I'll check barzilay.org.)
12:50 eli: Yeah.
12:50 tauntaun: Year long-course?  Or are you repeating the semester-long course?
12:50 eli: Even when I did it on paper, there were people who wouldn't even bother getting their graded exams back.
12:51 (join) sethalves
12:51 eli: One semester, repeated.
12:51 eli: It's pl.barzilay.org, btw -- which is one of the links I owed you.
12:51 tauntaun: Wow...the NEU undergrads are evidently not as serious as the grad students...
12:52 eli: Nah, I think it's roughly the same as other places -- in the US.
12:53 eli: Or maybe Israel has changed too, and it's just my outdated memory to blame.
12:53 eli: In any case, doing a paperless test improved that, since it's much easier to get and read the comments.
12:57 (quit) sethalves: *.net *.split
12:57 Lajla: eli, why? I personally find it easier to explain mathematical concepts in writing than verbally.
12:57 tauntaun: The Friedman/Wand/Hand book doesn't seem to be downloadable as PDF.  Is it worth buying?
