I use Emacs' org-mode for data science and for math courses. With Babel you can evaluate code and see the results in-line, with syntax highlighting. I don't use code completion myself but I'm confident it's available. With LaTeX preview, you can see mathematical formulae pre-rendered, again in-page.

You can then export from org-mode to LaTex, defining all the relevant settings at the top of the page.

Also, I wonder if someone will hook Spec up to DevCards directly for automatic UI testing. Seems like the logical next step, instead of manually putting the generated tests into DevCards.

Laphman has reminisced in a few of his essays about growing up in his august family in San Francisco - wonderful memories, windows into bygone eras. The pleasure of reading his essays, as for the magazine itself, lies in the prose itself even more than the ideas.

Someday I'll buy all the back issues.

No, an elephant needs a larger brain to run its larger body. Humans have enough brains to run our bodies, plus "extra" with which to think, in a manner of speaking.

I've always thought the metabolic needs must have been just as driving (specifically, being carnivores). Note: not a dig at vegetarians, we're talking about long before the proliferation of tofu and quinoa.

Fantastic, happy to see this development. I keep a list of people/Patreons to support, and Kalid has been on it for a long time

Really appreciate it, thank you.

Thanks for the reviews, that's quite helpful. I'm taking Andrew Ng's course again, and really enjoying it. I understood most of it the first time, but having linear algebra and calculus is a huge help this time around.

Thanks for this article - very clear, well-motivated, and concise. I'm saving this for myself and others.

Here's a good (and fun) column on how Ms. Kondo helps many people overcome cognitive biases.

No, I (and presumably the other posters) can tell the difference - I just disagree on the morality, partly because I think the legal aspects are related to the moral aspects.

The guy purchased the right to the house once the current owner dies, but you believe it's immoral for her to continue living in it, or renting it out, or loaning it to friends, while she is alive. I think it's immoral to demand the house while she's alive, since that wasn't the deal.

Sometimes legality and morality are widely separated, but here they seem related.

"Biohack" is pretty common - although that term also means, e.g, implanting magnets in your fingers.
