So, just to be clear, you're taking issue with the mentality expressed as: “They got dramatic results,” says Hinton. “Their very first results were about as good as the state of the art that had been fine-tuned for 30 years, and it wa

Definitely. My (indirect) point was that scientific computing is a much less competitive area than Go and Rust are targeting. And I can imagine a world where NumPy, R, and Julia are all strong projects. Arguably, lack of commercial support

The extended quotation is: When Hinton’s group tested this model, it had the benefit of something unavailable at the time neural nets were first conceived — super fast GPUs (Graphic Processing Units). Though those chips were designed to ch

True, but unlike Go or Rust, it probably only needs to be better than Matlab to have a successful future.

I took that quote as an example of the resources put into that evaluation: if two students in a lab can quickly get something competitive up and running, then we're likely to do very well if we throw more resources and expertise at the

This isn't quite true. I know of several R packages that I've had to build from source on Linux and I'd be worried about installing on windows (Combinations and Cranvas come to mind). Generally the packages that aim for highe

I didn't know about the JIT mode. Thanks for the specific pointer.

Are you sure you're referring to JIT as opposed to byte-compilation?

AUCTeX mode is great; less well known is CDLaTeX mode, which has a lot of quick abbreviations for mathematical symbols, etc. I'm a huge fan: https://staff.fnwi.uva.nl/c.dominik/Tools/cdlatex/cdlatex.el

I know lots of adults that can't use fractions correctly. I don't know how that fits in with "basic" vs "useless" math, but it doesn't give me much hope for programming (unless, like you said, 'progra

That much grading in that short of a time is bullshit. Sorry that you've had that dumped on you. But you're right, it's not going to pay off to complain about it.

Just want to point out to anyone upset that his lectures and notes have been taken offline: MIT's OCW is typically CC-BY-NC. Anyone is free to share their backup copy of the lectures online as a replacement.

As with most algorithms, there are trade-offs :). An advantage of the poem is that it can be learned by small children. I disagree that your approach can't be mixed up... I'm still trying to figure out what nomth is so I can imple

Yes, like most poems, this is one that you're better off remembering than trying to reconstruct on the fly.

I've had the opposite experience. The mailing lists are friendly and, to the extent that I've seen people involved with the project claim superiority, it's in the very narrow context of scientific computing. (I mean, it'

Not quite native, but you can use Knitr with Julia. Carson Sievert (IA State stats grad student) has written up some slides: http://heike.github.io/stat590f/gadfly/carson-knitr IJulia[1] is probably closest to the

Only loosely related, but I would love to see multiple dispatch come to Julia's macros. I seem to spend a fair bit of each macro switching on the expression's head, and would happily offload that step. (Of course, that might be gr

I'd amend that a little: use a matrix when you're actually calculating statistics (internally to the function). Clean your data so it always fits in a data frame when you load it. Lists are for representing things like data scrape
