@rob: It seems that I am installing logic in a .jar ;-)

seriously, i don't feel like relearning how to copy and paste stuff and in what direction <del> works just to feel superior for no reason

@t.b.: fresh air, what is that?

you only have to understand your own TeX long enough to finish your answer :)

Because that math is ugly and mostly inaccurate?

Ah, it's week-end again, so the chat becomes @Asaf's Kitchen Show™

@JM It's always hard to tell seriousness from irony online. If the latter: I guess you're hanging out too much with mathematicians :p

@Ramana: That's because you decided to multitask instead of thinking about what I said

@robjohn: Even my students don't call me "Dr. Spivey." :)

@MikeSpivey re: keeping you sharp. Maybe you had this post by Matt E in mind?

robjohn

Oct 20, 2011 19:01

But since it helps students learn, and doesn't make them wait until the next section to be corrected, I will live with the guilt

robjohn

Oct 20, 2011 18:59

some cases it needs to get some information about the substitution from the user (in the form of a multiple choice question about which is the proper form they were thinking of)

Asaf Karagila

Oct 20, 2011 18:54

That is they build proofs and it tells them what is wrong, or is it some multiple choice kind of thing?

@Ramana: I currently write software to teach logic to students at UCLA, and it is also used in about a dozen other schools.

Anyway, I'm gonna make JM soooooo jealous.

@robjohn: I'm always glad to mess up somebody's attempt at a post so that they can write a better second attempt. :)

As long as you post helpful and interesting stuff, you could be single-celled for all I care.

I've seen that question, but I've yet to see a blog look anywhere near as good as MSE.

There are so many lazy questions here recently. Many of them are simply answered by entering the title into Google...

Too much thought for a problem with so little scope. I don't know if I can use the result anywhere else. Maybe if I were an economist.

no, I haven't entered an email address in my bio, so my gravatar depends on my IP address. My provider changes it every 12 hours or so, hence I'm looking differently from time to time :)

oh, I didn't realize in a math chat I might be a bit ambiguous calling the characters "completely one-dimensional"...

I love writing proofs on this site for things that I don't know and have to come up with them on the spot. Especially when I am correct.

I have an interesting Mario Kart question I'll post sometime (involves permutation matrices as well) :)

@JM: You have deleted two whole characters from Isaac's old post? Incredible! :P
