Good to hear! Please say hi to everyone. I used to hang out in the group back when it was still at Tech^2.

Looks like MIT Scheme (on which the ScmUtils system runs) still gets some regular maintainence releases, though I don't know how active development is these days: https://www.gnu.org/software/mit-scheme/ htt

I didn't grow up in the Bronx, but did live there. I remember the one Barnes & Noble (fondly) and am glad to hear this news.

So was I, something more like this: http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.32.... Still, I thought it was a nice post.

I like my 2018 MBP. I even like the keyboard. The touch bar is kinda "meh," but I think it's more a software issue than hardware: Apple's interface guidelines make no sense to me. Why can't developers use it to g

Not a biologist, but I'd imagine that's because we currently can answer "is this DNA likely the same as that other DNA" with some degree of reliability, but anything more (except for some very specific diseases) is still

I got rid of Netflix DVD by mail only because I'm lucky (I think) to still have a locally owned and operated video rental store on my way to and from work.

Seems like AYBABTME is talking about constrained optimization, whereas you are speaking of "constraints" in a different context, i.e., this paper ( https://dspace.mit.edu/handle/1721.1/6255 ) by Stallman a

No, not quite. Roughly speaking, he's asking about the computational complexity of solving problems (producing proofs of statements in first-order predicate logic) with a given bound N on the size of the solution. This is computable

Agreed this would be the case. I read it for the first time as an adult, and thought it well written. Around the same time I re-read the original Foundation trilogy, which I hadn't touched since high school, and was disappointed by t

Oh gosh, packrats are such a PIA. They seem to love garages when they can get in -- I guess no snakes, no birds of prey, no bobcats, etc. And this thing about chewing wires in cars.

I've been hoping for something like this for some time (and have thought Apple might be moving in that direction with the Touch Bar etc). It may just be the way I type, and I may well be in a minority, but I'd much prefer a confi

I assumed that he was talking about the possible point groups in 2d (since his demo was a slide). In 2d lattices, the possible point groups are cyclic groups of order 2,3,4,6. Cyclic groups of order 5 cannot occur; one consequence is that

Flip side of this: if there is a teacher / professor who's made a difference in your life, and you have the means & the opportunity to do so, drop by and say hi. As someone who's been teaching for a little while, it is t

I work in an academic setting. If I had the choice I'd prefer Python (or even Julia), but frequently Matlab is what's appropriate in a lower-division STEM (non-CS) course because it's what many engineers are used to and teac

In my experience one can pretty much just copy and paste, and most things work (though likely not 100%). There are two ways in which Octave still falls short: (1) Matlab is faster, as it has (I believe) JIT compilation whereas Octave doesn

I got my email address when I started college, in the early 90s. You didn't use it much except to communicate with people you knew in real life. It replaced letter-writing, certainly, but otherwise not a huge change. During college y

In the US you find both. More commonly CS came from electrical engineering, but you do find some departments that started as part of mathematics. In any case, as other commenters said, early "computer scientists" often came from

I agree with everything you say. Just want to add that SICP had a context: it was designed to be an introductory computer science course designed for university engineering students (including CS), almost all of whom take calulus in their

All good points, but there are a couple mistakes I often see people (not just beginners) make that did not get mentioned: 1. State the problem (and convince the audience it matters) before rushing to present a solution. 2. Know the backgrou

Perhaps. Presenting overly complex & technical information happens a lot, but I think there are other explanations. Wanting to impress one's peers, for example. After all, the last 10% technical detail is often where one spent 9

First time I saw this thing was on a drive from Southern Arizona to San Diego. (There really aren’t that many reasons to be out there.) The pyramid is clearly visible from the Interstate. I remember thinking: “WTF is this doing here?” It wa
