I complete agree with your case analysis, but disagree with the conclusion that the code needs to be runnable for it to be useful -- I thought this was the point of the discussion at hand? In most situations, having source code, even if i

I agree with the case analysis, but disagree with the implication that the code needs to be runnable (which is seems to be the point of the discussion at hand). In many cases having source code, even if it no longer runs, should be suffi

To throw in one more data point: several years ago I wrote a simulator for a paper, it involves tracking large numbers of particles bouncing through a 2D space with different geometries. There's a front end, in PLT Scheme, and a backe

This is not clear at all. It depends on the "result" in question. If I wrote a paper describing a super numerical algorithm for inverting matrices, and no one is able to replicate the superior performance of my algorithm despite

This. I absolutely agree there needs to be more transparency, and scientific code should be as open as possible. But this should not replace replication.

Reminds me of this: https://en.wikipedia.org/wiki/Rejecta_Mathematica which sadly did not last.

And I've wondered if the blurring of the line between research and product development at the likes of Google and Facebook (MS Research seems to still be an exception) is because they feel they have less breathing space?

Oh, how I wish I still had my SE/30. Looking back through rose-tinted glasses, still the machine I had the most fun using. (Partly because of the machine, partly because everything I did on a computer back then was fun.) Anyway, good

The making of slides (or sentences in a paper) gets easier with practice. The advisor or collaborator or you yourself being too busy is, unfortunately, not something that gets better with time. The most important thing is learning to say

Ditto! I also try to never tell the kids "don't ask that question." Though very often I do need to answer with "I don't know, but let's find out if anyone does," then research it later. And occasionally,

I think this is in general quite insightful, but I want to pick one nit (in reaction to "A professor doesn't tell you when to..."): having advised a number of PhD students (in applied math), I think one of the most important

Came here to post this! I don't know much about architecture, but found both well worth visiting. Taliesin West is in Scottsdale, northeast of Phoenix. Arcosanti a bit farther north of Phoenix, but on the way to destinations north

For anyone who wants to know more about Courant’s life, the people he crossed paths with (which include some of the great mathematicians of the 20th C), and how NYU came to have the Courant Institute, Constance Reid’s biography is and nice

That was beautifully said. Thank you for sharing. Alas, gems like this is also why I'm addicted to HN.

Exactly. This idea has merit and is worth thinking about. But in much of the Sun Belt, with some of the worst-hit states, it's going to be pretty hard to do until October or so: if it's not temp + humidity, it's sheer temp

This is in part cultural. In UK, much of Asia, and continental Europe, students specialize earlier. On average, most degree programs (and especially professional degrees like MD) take longer in the US system. Not saying this is necessari

Oh, I completely agree with that. One of the issues, especially at large public universities, is that many faculty members who are perfectly effective in person have difficulties with the technology. Asking them to split attention on top

Those are nice points; I quite agree there are things one can do to engage people over Zoom etc. But it's less spontaneous and takes more prior planning. Also, many students simply do not want to ask a question in front of their peer

Oh absolutely, there are many differences between in person and online, and (as you said) the size of the audience definitely matters. Part of the job of instructors is to work the crowd, and in that sense it is not different from any othe

There are practical difficulties in having some students in the classroom and some students online: it's hard for a single instructor to split attention that way, unless they have some help (e.g., a student assistant) in the classroom.

Re cameras, mine is the opposite: a colleague in a different department was told one cannot require that cameras be one. Most students do not volunteer to turn them on, and very few leave their microphones on. No feedback this way either.

I teach mathematics at a large R1 state university. His comments echo my experience. Online is really different, both for the instructor AND for the student. Most instructors don't know how to teach online, and most students (even v

Exactly. Getting a PhD means 1. taking some advanced math classes 2. hanging around some like-minded people for a few years 3. solving a problem or two, big enough to add up to a dissertation 4. publish, with professional help on learning

Absolutely. I guess I was trying to say (not very clearly) that ScmUtils was the only other example I know of that "ran with it." Though SICM is relatively well known at this point, I suspect ScmUtils is not very widely used.

I don't think Julia is (or has ever claimed to be) the first system to make extensive use of multiple dispatch. But it seems to be first one to have gotten attention, if not widespread adoption, from the broader community beyond its f

As much as I love Gould's recordings, this one made me hear something new. Thank you!

My impression is that dropping Scheme is something that some students have demanded for a long time, maybe even since the beginning. Back when I took 6.001 (in the 90s) there were certainly fellow Course 6ers who'd rather learn more &
